In 1979, Daniel Brélaz became the world's first green member of a national parliament (in Switzerland).

A green party is a formally organized political party based on the principles of green politics, such as social justice, environmentalism and nonviolence.

Greens believe that these issues are inherently related to one another as a foundation for world peace. Green party platforms typically embrace social-democratic economic policies and form coalitions with other left-wing parties.

Green parties exist in nearly 90 countries around the world; many are members of Global Greens.

Definitions

There are distinctions between "green" parties and "Green" parties. Any party, faction, or politician may be labeled "green" if it emphasizes environmental causes. In contrast, formally organized Green parties may follow a coherent ideology that includes not only environmentalism, but often also other concerns such as social justice, consensus decision-making and nonviolence. Greens believe that these issues are inherently related to one another as a foundation for world peace. The best-known statement of the above Green values is the Four Pillars of the Green Party, adopted by the German Greens in 1979–1980 (but forsaken since). The Global Greens Charter lists six guiding principles which are ecological wisdom, social justice, participatory democracy, nonviolence, sustainability and respect for diversity.

History

Political parties campaigning on a predominantly environmental platform arose in the early 1970s in various parts of the world.

The world's first political parties to campaign on a predominantly environmental platform were the United Tasmania Group contested the April 1972 state election in Tasmania, Australia, and the Values Party of New Zealand, which contested the November 1972 New Zealand general election. Their use of the name 'Green' derived from the 'Green Bans': an Australian movement of building workers who refused to build on sites of cultural and environmental significance.

The first green party in Europe was the Popular Movement for the Environment, founded in 1972 in the Swiss canton of Neuchâtel. The first national green party in Europe was PEOPLE, founded in Britain in February 1973, which eventually turned into the Ecology Party, and then the Green Party. Several other local political groups were founded in beginning of the 1970s and Fons Sprangers was probably the first Green mayor in the world, elected in 1970 in Meer, and active until 2020 for the Flemish Greens. The first political party to use the name "Green" seems to have been the Lower Saxon "Green List for Environmental Protection", founded on 1 September 1977.

The first Green Party to achieve national prominence was the German Green Party, famous for their opposition to nuclear power, as well as an expression of anti-centralist and pacifist values traditional to greens. They were founded in 1980 and have been in coalition governments at state level for some years. They were in federal government with the Social Democratic Party of Germany in a so-called Red-Green alliance from 1998 to 2005. In 2001, they reached an agreement to end reliance on nuclear power in Germany, and agreed to remain in coalition and support the government of Chancellor Gerhard Schröder in the 2001 Afghan War. This put them at odds with many Greens worldwide.

In Finland, in 1995, the Finnish Green Party was the first European Green party to be part of a national Cabinet. Other Green parties that have participated in government at national level include the Groen! (formerly Agalev) and Ecolo in Belgium, The Greens in France and the Green Party in Ireland. In the Netherlands GroenLinks ("GreenLeft") was founded in 1990 from four small left-wing parties and is now a stable faction in the Dutch parliament. The Australian Greens supported a Labor minority government from 2010 to 2013, and have participated in several state governments.

In 2022 Denmark, the Green Party The Alternative has only one Parliament member, having dropped from the previous nine, and five local parliaments members. In 2022 Portugal, the Green Party People-Animals-Nature also has only one Parliament member, having dropped from the previous four, and another in the Madeira Regional Parliament, while its two other Green parties, Partido da Terra and Partido Ecologista "Os Verdes", only have, respectively, two councilpeople and one mayor.

Around the world, individuals have formed many Green parties over the last thirty years. Green parties now exist in most countries with democratic systems: from Canada to Peru; from Norway to South Africa; from Ireland to Mongolia. There is Green representation at national, regional and local levels in many countries around the world.

Most of the Green parties are formed to win elections, and so organize themselves by the presented electoral or political districts. But that does not apply universally: The Green Party of Alaska is organized along bioregional lines to practice bioregional democracy.

Support

Academic research has uncovered striking international consistency in the typical demographic and attitudinal profile of Green party supporters. In particular, Green voters tend to be young, highly educated, disproportionately female, and employed in the social and cultural services (healthcare, teaching, the arts, etc.), whilst also displaying above-average levels of environmentalism and social liberalism, as well as being left-leaning. Additionally, Green parties also tend to attract greater levels of support in countries defined by high levels of economic development and low levels of unemployment, as well as the presence of tangible environmental disputes (such as nuclear power production) and active major party competition on the environmental issue. The former two factors are believed to generate cohorts of voters with enough material security to devote their attention to 'higher' goals such as environmentalism; the latter two help raise the profile of the Green's own policy positions and statements (providing that the major parties do not act so quickly to the rising salience of environmentalism as to usurp the issue entirely and completely preempt the development of a separate ecological party). Their supporters sometimes blame the economical system for the environmental issues neglecting any green free-market liberal capitalist alternatives.

Alliances

Depending on local conditions or issues, platforms and alliances may vary. In line with the goal of democracy, neighboring ecoregions may require different policies or protections.

Green parties are often formed in a given jurisdiction by a coalition of scientific ecologists, community environmentalists, and local (or national) leftist groups or groups concerned with peace or citizens rights.

A Red-Green alliance is an alliance between Green parties and social democratic parties. Such alliances are typically formed for the purpose of elections (mostly in first-past-the-post election systems), or, after elections, for the purpose of forming a government.

Some Greens, such as those in Hawaii, find more effective alliances with more conservative groups (Blue-Green alliance) or indigenous peoples - who seek to prevent disruption of traditional ways of life or to save ecological resources they depend on. Although Greens find much to support in fostering these types of alliances with groups of historically different backgrounds, they also feel strongly about forming diverse communities through encouragement of diversity in social and economic demographics in communities, especially in the United States.

Alliances often highlight strategic differences between participating in parties and advancing the values of the Green movement. For example, Greens became allied with centre-right parties to oust the centre-left ruling Institutional Revolutionary Party of Mexico. Ralph Nader, the 2000 presidential nominee of the U.S. Greens, campaigned with ultra-conservative Pat Buchanan on joint issues such as farm policy and bans on corporate funding of election campaigns, although this "alliance" between Nader and Buchanan was very specifically limited to the purpose of showing that there was broad support for certain specific issues, across the political spectrum.

U.S. Greens grew dramatically throughout 2001. However, stable coalitions (such as that in Germany) tend to be formed between elections with left-wing parties on social issues, and 'the grassroots right' on such issues as irresponsible corporate subsidies and public ethics.

On 13 June 2007, the Irish Green Party, represented by six members of parliament or TDs, agreed to go into a coalition government for the first time in their history, with Fianna Fáil and the Progressive Democrats (the Progressive Democrats later dissolved as a party, though their members remained in parliament). The Green Party held two Cabinet seats, as well as two junior ministries, until their withdrawal from government in January 2011. They lost all of their six seats in the following month's general election, but won two in the 2016 general election, and twelve seats in the 2020 general election, and entered government again in June 2020.

In the Czech Republic, the Green Party was part of the governing coalition, together with the conservative Civic Democratic Party (ODS) and the Christian Democrats (KDU–ČSL) from January 2007 until the government collapsed in March 2009.

Green parties

Africa

Some national Green parties began forming in Africa in the 1980s and 1990s, but they often struggled to gain influence.

Wangari Maathai was perhaps the most prominent and successful member of a Green party in Africa: after founding the Green Belt Movement and the Mazingira Green Party of Kenya, she was elected to the Kenyan Parliament in 2002, became an assistant minister for Environmental and Natural Resources, and won the Nobel Peace Prize in 2004. Other African Green parties that have achieved parliamentary representation include Les Verts Fraternels of Mauritius, and Frank Habineza's Democratic Green Party of Rwanda. In Senegal, Green party leader Haïdar el Ali was appointed Minister for Ecology in 2012.

Asia and Oceania

Australia, Fiji, New Zealand, Papua New Guinea, Vanuatu

See also: Asia Pacific Greens Federation

Green parties have achieved national or state parliamentary representation in New Zealand, Australia and Vanuatu. In New Zealand the Green Party of Aotearoa New Zealand currently holds 10 seats in the New Zealand House of Representatives after the 2020 general election. The Australian Greens hold 10 seats in the Australian Senate and one seat in the Australian House of Representatives. Since 2004, they have received more votes than any other third party in every federal election. They also have representation in the upper and lower houses of state parliaments of five states and in the unicameral chamber of one territory. Greens also hold representative positions in local government across New Zealand and Australia (where a number of local government authorities are controlled by Green councilors). The Greens took the seat of Melbourne from the Australian Labor Party in 2010 with candidate Adam Bandt. This is the first time the Greens have won a Lower House seat at a general election (although they have previously won two seats at by-elections).

Proportional representation in the Australian Senate and in New Zealand has strengthened the position of the Australian Greens and the Green Party of New Zealand and enabled them to participate directly in legislatures and policy-making committees. In countries following British-style 'first past the post' electoral rules, Green parties face barriers to gaining federal or provincial/regional/state seats. The Australian Labor Party's practice of allocating a portion of ALP ticket votes to Australian Greens has helped bring AG candidates into parliament.

In the 2008 ACT election in Australia, the Greens won 15.6% of the vote, winning 4 out of 17 seats. Shane Rattenbury was elected the speaker of the assembly, the first time a Green party member had held such a position in any parliament or assembly in Australia. However, they retained only one seat at the 2012 election in the same territory.

The Green Confederation (Confédération Verte) in Vanuatu won 3 out of 52 seats in the last general election in October 2012. Its most prominent member is Moana Carcasses Kalosil, who became prime minister in March 2013. Carcasses, a Green liberal, does not lead a Green government, but a broad coalition government in which he is the only Green minister.

There is a Papua New Guinea Greens Party, but it does not have any members in Parliament. There was briefly a Green Party in Fiji from 2008 to 2013; as Parliament was suspended by the military regime during this time, the party was not able to take part in any election before all parties were deregistered in 2013.

Lebanon

The Green Party of Lebanon was founded in 2008 as a secular party. Its first president was Philippe Skaff, CEO of Grey Advertising. The party debuted with the May 2010 municipal elections. In 2011, the party became the first political party in Lebanon to elect a female leader when Nada Zaarour was elected its president.

Pakistan, Saudi Arabia

The Green Party of Pakistan was founded in 2002, and the Green Party of Saudi Arabia emerged 2010. However, due to political repression, some South and Southwest Asian Green parties are underground organizations.

Taiwan

The Green Party Taiwan was founded in 1996. It is a small party which have often associated with Democratic Progressive Party, a major political party in Taiwan.

Europe

Belgian and German roots

The first green parties in Europe were founded in the late 1970s, following the rise of environmental awareness and the development of new social movements. Green parties in Belgium first made a breakthrough. Belgium had Green members of parliament elected first in the 1970s, and with seats on the local council, held the balance of power in the city of Liege, so were the first to go into coalition with the ruling party on that council. In 1979 political campaigns and dissident groups feeling underrepresented in west German politics formed a coalition to contest the 1979 elections to the European Parliament.

Although they did not win any seats, the groups in this association formally agreed to become a party and won a breakthrough in the German national elections of 1983. They were not the first Green Party in Europe to have members elected nationally but the impression was created that they had been, because they attracted the most media attention. This was partly due to their charismatic leader Petra Kelly, a German who was of interest to the American media because she had an American step-father. Since its foundation in 1980 and merger with Alliance 90 after the German reunification, Kelly's party, now named Alliance '90/The Greens, has become one of Europe's most important Green parties. It played an important role in the formation of national-level Green parties in other countries such as Spain as well. The forerunner of the Green Party in the United Kingdom was the PEOPLE Party, formed in Coventry in 1972. It changed its name to the Ecology Party in 1973 and the Green Party in 1985.

1984–1989: A new political force

In 1984 Greens agreed a common platform for the European Parliament Elections and the first Green Members of the European Parliament were elected here. Germany, a stronghold of the Green movement, elected seven MEPs; two more came from Belgium and two from the Netherlands. As those eleven MEPs did not entitle the Greens to form a parliamentary group on their own, they concluded an alliance with MEPs from Italy, Denmark, and regionalists from Flanders and Ireland to form the GRAEL (Green Alternative European Link) group, also known as the Rainbow Group. Politically they engaged in the fight against environmental pollution, nuclear energy (1986 saw the Chernobyl disaster), the promotion of animal protection and the campaign against the demolition of Brussels by speculation fuelled by the presence of the European institutions.

Since the 1990s

Indulis Emsis of the Latvian Green Party became Prime Minister of Latvia in 2004, and the world's first green head of government.

After years of co-operation between the national Green parties, they formed a pan-European alliance that unites most European Green parties. The Greens are a party within the European parliament with 46 seats, as of June 2009. It has a long-standing alliance with the European Free Alliance (EFA), an alliance of "stateless nations", such as the Welsh nationalist Plaid Cymru and Scottish National Party. Together European Green Party/EFA have 58 seats and they are the fourth largest party in the European Parliament.

While on many issues European Greens practice the same policies, one issue divides European Green parties: the European Union. Some Green parties, like the Dutch GreenLeft, the Green Party of England and Wales, the Swiss Green Party, the Irish Green Party and the German Alliance '90/The Greens, are pro-European while some, like the Green party in Sweden, are moderately eurosceptic.

Some Green parties have been part of governing coalitions. The first one was the Finnish Green League that entered government in 1995. The Italian Federation of the Greens, the French Greens, the German Alliance '90/The Greens and both Belgian Green parties, the French-speaking Ecolo and the Dutch-speaking Agalev were part of government during the late 1990s. Most successful was the Latvian Green Party, who supplied the Prime Minister of Latvia in 2004. The Swedish Green Party was a long term supporter of the social-democratic minority government until the election 2006 when the social-democratic party lost. The Irish Green Party is currently in government, having entered a coalition with Fianna Fáil and Fine Gael in June 2020, with three cabinet positions. It was previously in a coalition government with Fianna Fáil from 2007 until January 2011 when the party withdrew their support for the ruling coalition.

Raimonds Vējonis, President of Latvia

 

Alexander Van der Bellen, President of Austria

Vējonis (elected 2015) and Van der Bellen (elected 2016) are Europe's first two green heads of state.

In Scandinavia, left-wing socialist parties have formed the Nordic Green Left Alliance. These parties have the same ideals as European Greens. However, they do not cooperate with the Global Greens or European Greens, but instead form a combined parliamentary group with the Party of the European Left, which unites communists and post-communists. There is one exception, in 2004 the MEP for Danish Socialist People's Party has left the Nordic Green Left parliamentary group and has joined the Green parliamentary group in the European parliament. The Socialist People's Party is currently an observer at the European Green Party and the Global Greens. Outside of Scandinavia, in 2004, Latvia became the first country in the world to have a Green politician become Head of Government, but in 2006 the Green Party received only 16.71 percent of the vote. In the Estonia 2007 parliamentary elections, the Estonian Greens won 7.1 percent of the vote, and a mandate for six seats in the country's parliament, the Riigikogu. Other significant electoral results for European green parties include Germany's Alliance '90/The Greens in the 2002 federal election and France's Europe Ecology – The Greens in the 2012 legislative election, in which they both won more seats than any other third party.

British MP Caroline Lucas is the UK's first (and, to date, only) green politician elected under the first-past-the-post system.

In some countries Greens have found it difficult to win any representation in the national parliament. Three reasons can be found for this. It includes countries with a first past the post electoral system, such as the United Kingdom. However, despite the first past the post system in the United Kingdom, the Green Party of England and Wales won their first seat in the House of Commons when Caroline Lucas won the seat of Brighton Pavilion in 2010. The Scottish Greens have had success in the devolved Scottish Parliament having recently signed a deal to enter a governing coalition, whilst the Green Party Northern Ireland has had success in the devolved Northern Ireland Assembly and local elections where the first-past-the-post system is not used. In countries where a party with similar ideals is stronger, such as Norway and Denmark, Green parties tend to perform worse. In some Eastern European countries, like Romania, Green parties are still in the process of formation and have therefore not gained enough support. In Poland the Green Party, registered in 2004, won their first three seats in the Sejm in 2019. The Green Party of Bulgaria is a part of the left-wing Coalition for Bulgaria, currently in opposition. It has no parliamentary representation but it did supply one Deputy Minister in the government of Prime Minister Sergey Stanishev from 2005 to 2009.

The European Green Party has worked to support weak Green parties in European countries. Until recently, they were giving support to Green parties in the Mediterranean countries. These Green parties are now making electoral gains, e.g. in Spain, Greece and Republic of Cyprus, or getting organized to do so, e.g. in Malta. Therefore, the EGP is now turning its attention to Eastern Europe – all these countries have Green parties, but in materially poor Eastern Europe the success of Green Parties is patchy except for Hungary, where the local Green party, Politics Can Be Different (LMP), has been elected to parliament and many city councils.

In 2021 Croatian local elections We can! party became the largest political party in the Zagreb Assembly, winning 23 seats in total. Their mayoral candidate Tomislav Tomašević won a landslide victory on 31 May.

Turkey

Greens and the Left Party of the Future is a left-libertarian and green party in Turkey. It was founded on 25 November 2012 as a merger of the Greens Party and the Equality and Democracy Party.

Prominent members include Murat Belge, left-liberal political author and columnist for Taraf; Kutluğ Ataman, filmmaker and contemporary artist; and Ufuk Uras, former Istanbul deputy and president of the Freedom and Solidarity Party.

The party is one of the participants in the Peoples' Democratic Congress, a political initiative instrumental in founding the Peoples' Democratic Party in 2012.

The Greens, along with feminists, left YSGP en masse in 2016, citing its lack of democratic decision making practices. They and a new generation of activists reestablished the Green Party (Yeşiller) in 2020.

North America

As of the 41st general election in Canada, held on May 2, 2011, there was only one federally elected member of the Green Party of Canada in the House of Commons of Canada, its leader Elizabeth May. However, at the dissolution of the 41st Parliament on August 2, 2015, the Green Party of Canada held two seats in the House of Commons, the second seat belonging to formerly Independent MP Bruce Hyer who was elected to the House of Commons as a member of the NDP in 2011. Only May won re-election to the 42nd parliament. There remains no federal representation by the Green Party of the United States in the U.S. Congress. Accordingly, in these countries, Green parties focus on electoral reform. In Mexico, however, the Partido Verde Ecologista, often abbreviated as PVEM, has 17 deputies and four senators in Congress as a result of the 2006 elections. Nevertheless, some of its political practices such as plead in favor of the death penalty in Mexico, led to the European Green Party's withdrawal of recognition of the PVEM as a legitimate green party.

Canada

See also: Green Party of Canada § Provincial parties, List of Green party leaders in Canada, and List of Green politicians who have held office in Canada

The first Green parties in Canada (both federal and provincial) were founded in 1983. The strongest provincial Green parties are the Green Party of British Columbia, the Green Party of Ontario, the Green Party of New Brunswick, and the Green Party of Prince Edward Island which was elected the Official Opposition in the 2019 election. The first ever BC Green MLA was elected in 2013, and in 2017 they helped the minority NDP form government. In 2014 a Green MLA was elected to the New Brunswick legislature, in 2015 a Green MLA was elected to the Prince Edward Island Legislature, and in 2018 Mike Schreiner became the first Green MPP elected to the Ontario provincial legislature. Federally, the Green Party of Canada received 6.49% of the popular vote and a record three seats in Parliament during the 2019 federal election, breaking ground in Atlantic Canada with the election of Jenica Atwin as the first federal Green from outside of British Columbia. This is up from one seat (later two) and 3.91% won in the 2015 federal election. Although Elizabeth May (the leader of the GPC from 2006-2019) was the first elected Member of Parliament, the first seat was gained in the House of Commons on August 30, 2008 when sitting Independent MP Blair Wilson joined the party. As of September 2020, May continues to sit as a Member of Parliament for Saanich-Gulf Islands and has exerted a considerable amount of legislative influence on a number of issues ranging from denying unanimous consent for military intervention in Libya, playing a central role in exposing changes to environmental legislation hidden in the omnibus Budget Bill C-38, to introducing a private member's bill to develop a national strategy on Lyme disease.

In the 2008 Vancouver municipal election, Stuart Mackinnon, a member of the Vancouver Green Party, was elected to the Vancouver Parks Board. Since that time former Green Party of British Columbia leader, and deputy-leader of the federal Green party, Adriane Carr won the Greens' first seat on Vancouver City Council, in 2011 municipal elections.

United States

In the United States, Greens first ran for public office in 1985. Since then, the Green Party of the United States has claimed electoral victories at the municipal, county and state levels. The first U.S. Greens to be elected were David Conley and Frank Koehn in Wisconsin 1986. Each was elected to a position on the County Board of Supervisors in Douglas and Bayfield counties respectively. Keiko Bonk was first elected in 1992 in Hawaii County, becoming Official Chairwoman in 1995. The first Green Party mayor  was Kelly Weaverling, elected in Cordova, AK in 1991.

As of April 2018, 156 Greens held elective office across the US in 19 states. The states with the largest numbers of Green elected officials are California (68), Connecticut (15), and Pennsylvania (15). Titles of offices held include: Alderman, Auditor, Board of Appeals, Board of Finance, Board of Selectmen, Borough Council, Budget Committee, Circuit Court Judge, City Council, Common Council, Community College District Board of Trustees, Community Service Board, Conservation Congress, Constable, County Board of Supervisors, County Supervisor, Fire Commission, Fire District Board, Inspector of Elections, Judge of Elections, Mayor, Neighborhood Council Board, Park District, Parks and Recreation District Board, Library Board, Planning Board, Public Housing Authority Resident Advisory Board, Public Service District, Rent Stabilization Board, Sanitary District Board, School Board, Soil and Water Conservation Board, State Representative, Town Council, Transit District Board, Village Trustee, Water District Board, and Zoning Board of Appeals As of October 2016, 100 Greens held elected office across the US. The first US Green elected to a state legislature was Audie Bock in 1999, to the California State Assembly, followed by John Eder to the Maine House of Representatives in 2002 and 2004 and Richard Carroll to the Arkansas House of Representatives in 2008. While in office in 2003 in the New Jersey General Assembly, incumbent Matt Ahearn made a party switch to Green for the remainder of his term.

The Green Party has contested six U.S.A. presidential elections: in 1996 and 2000 with Ralph Nader for president and Winona LaDuke as vice president, in 2004 with David Cobb for president and Pat LaMarche for vice president, and in 2008 with Cynthia McKinney for president and Rosa Clemente for vice president. In 2000, Nader received more votes for president than any Green Party candidate before or since. Jill Stein ran for president on the Green ticket in 2012 and 2016; the vice-presidential candidates were Cheri Honkala in 2012 and Ajamu Baraka in 2016. Stein, who received over one million votes in the 2016 race, led unsuccessful attempts toward 2016 election recounts in three states: Michigan, Pennsylvania, and Wisconsin.

South America

Brazil

The Brazilian Green Party was constituted after the military dictatorship period and, like other Green Parties around the world, is committed to establishing a set of policies on ensuring social-equity and sustainable development. One of the party's founding members was the journalist and former anti-dictatorship revolutionary Fernando Gabeira, Alfredo Sirkis and Carlos Minc. Among the main items on the Green Party's agenda are federalism, environmentalism, human rights, a form of direct democracy, parliamentarism, welfare, civil liberties, pacifism and marijuana legalization under specific conditions.

Green Party's candidate Marina Silva won 19.33% of the vote in the first round of the 2010 Brazilian presidential election (more than any other third party), taking enough votes from Dilma Rousseff of the incumbent PT to prevent her from achieving the majority of the vote needed to avoid a second round. Success in the legislature amounted to winning 2 more seats for a total of 15 in the Chamber of Deputies and the loss of their only senate seat.

Marina Silva left the party the following year.

In the 2014 presidential election the Green Party's candidate Eduardo Jorge received 0,61% of the vote. He garnered attention for campaigning on a progressive platform supporting policies such as cannabis legalization and the decriminalization of abortion. Because of his perceived eccentricity and spontaneity while participating in the televised debates, Jorge became the subject of several memes on the internet. The party elected 6 federal deputies and 1 senator.

In 2016, the Greens in Congress voted in favour of the impeachment of Dilma Roussef. The party later went on to support president Michel Temer who succeeded her.

For the 2018 presidential election the party formed the coalition United to transform Brazil with the Sustainability Network (REDE), in support of the candidacy of Marina Silva in her third run for the presidency. Eduardo Jorge was chosen as her running mate. Despite faring well in the initial polls, Silva ultimately received 1% of the vote. The party elected 4 federal deputies.

Colombia

In the 1990s, the Oxygen Green Party was created under the leadership of Ingrid Betancourt but dissolved after her infamous kidnapping. Later, the Visionaries Party was created by Antanas Mockus whose ideals earned him the Bogotá Mayoral Office twice. In the 2010 Colombian presidential election a green party has been created under the name Colombian Green Party, with former Bogotá mayor Antanas Mockus being the leader.

Climate change in China

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Climate_change_in_China 

 

Warming stripes of China between 1901-2019

Climate change in China is having major effects on the economy, society and the environment. China is the largest emitter of carbon dioxide, through an energy infrastructure heavily focused on fossil fuels and coal. Also, other industries, such as a burgeoning construction industry and industrial manufacturing contribute heavily to carbon emissions. However, like other developing countries, on a per-capita basis, China's carbon emissions were considerably less than countries like the United States: as of 2016, they were the 51st most per capita emitter. It has also been noted that higher-income countries have outsourced emissions-intensive industries to China. On the basis of cumulative CO₂ emissions measured from 1751 through to 2017, China is responsible for 13% globally and about half of the United State's cumulative emissions.

China is suffering from the negative effects of global warming in agriculture, forestry and water resources, and is expected to continue to see increased impacts. China's government is taking some measures to increase renewable energy, and other decarbonization efforts, vowing to hit peak emissions before 2030 and be carbon neutral by 2060 by adopting “more vigorous policies and measures.”

Greenhouse gas emissions

This section is an excerpt from Greenhouse gas emissions by China.

 

China's Emissions per person are above the world average

Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning in China, including coal-fired power stations, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO_2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for over 27% of global emissions.

Despite having the largest emissions in the world, China's large population means its per person emissions have remained considerably lower than those in the developed world. This corresponds to over 10.1 tonnes CO_2eq emitted per person each year, slightly over the world average and the EU average but significantly lower than the second largest emitter of greenhouse gases, the United States, with its 17.6 tonnes per person. In consumption terms, China emits slightly less, with over 6 tonnes in 2016, slightly above the world average, but less than the EU average (close to 8 tonnes) and less than the United States by more than a half, with close to 18 tonnes per person.^[14][15] Accounting for historic emissions, OECD countries produced four times more CO2 in cumulative emissions than China, due to developed countries' early start in industrialization.

Impacts on the natural environment

China has and will suffer some of the effects of global warming, including sea level rise, glacier retreat and air pollution.

Temperature and weather changes

There has also been an increased occurrence of climate-related disasters such as drought and flood, and the amplitude is growing. These events have grave consequences for productivity when they occur, and also create serious repercussions for the natural environment and infrastructure. This threatens the lives of billions and aggravates poverty.

A study published in 2017, using continuous and coherent severe weather reports from over 500 manned stations from 1961 to 2010, found a significant decreasing trend in severe weather occurrence across China, with the total number of severe weather days that have either thunderstorm, hail and/or damaging wind decreasing about 50% from 1961 to 2010. The reduction in severe weather occurrences correlated strongly with the weakening of the East Asian summer monsoon.

China observed a ground average temperature increase of 0.24℃/decade from 1951 to 2017, exceeding the global rate. The average precipitation of China was 641.3 mm in 2017, 1.8% more than the average precipitation of previous years. There was an annual increase in concentrations of carbon dioxide from 1990 to 2016. The annual mean concentration of atmospheric carbon dioxide, methane, and nitrous oxide at Wanliguan Station were 404.4 ppm, 1907 ppb, and 329.7 ppb separately in 2016, slightly higher than the global mean concentration in 2016.

Sea level rise

Coastal cities such as Guangzhou are vulnerable to sea level rise

The sea level rise was 3.4mm/year from 1980 to 2019 compared to the global average of 3.2mm/year.

China's first National Assessment of Global Climate Change, released in the 2000s by the Ministry of Science and Technology (MOST), states that China already suffers from the environmental impacts of climate change: increase of surface and ocean temperature, rise of sea level. Temperatures in the Tibetan Plateau of China are rising four times faster than anywhere else (data from 2011). Rising sea level is an alarming trend because China has a very long and densely populated coastline, with some of the most economically developed cities such as Shanghai, Tianjin, and Guangzhou situated there. Chinese research has estimated that a one-meter rise in sea level would inundate 92,000 square kilometers of China's coast, thereby displacing 67 million people.

Climate change caused an increase in sea level, threatening to impair the functions of harbors.

Rising sea levels affect China's coastal land.  Cities along the coast such as Shanghai, only 3–5 meters above sea level leaves its 18 million residents vulnerable.  Sea levels in Victoria Harbor in Hong Kong have already risen .12 meters in the last 50 years.

Ecosystems

Climate change increases forest belt limits and frequencies of pests and diseases, decreases frozen earth areas, and threatens to decrease glacial areas in northwest China. The vulnerability of ecosystems may increase due to future climate change. In the years 1970-2016 the occurrence of crop pest and diseases increased 4 times. 22% of that rise are due to climate change. By the year 2100 the occurrence will rise 243% under a low emission scenario and by 460% under a high emissions scenario. China is the biggest producer of wheat and rice in the world. It is in the second place in maize production.

Desertification Control Project, Ningxia China

China is home to 17,300 species of plants and animals: 667 vertebrates, ancient flora and fauna. Due to rising global temperatures, within the next century 20-30% of species will go extinct.

More than one fourth of China is covered by desert, which is growing due to desertification.  Desertification in China destroys farmland, biodiversity, and exacerbates poverty.

Water resources

Climate change decreased total water resources in North China while increasing total water resources in South China. There were more floods, drought, and extreme weather events. There may be a big impact on the spatial and temporal distribution in China's water resources, increasing extreme weather events and natural disasters.

Glacier melting in the Northern Region of China causes flooding in the upper parts of the Yangtze River.  This ruins soil and arable land.  The glacial melting causes lower parts of the Yangtze River to have lower volumes of water, also disrupting farming.

Furthermore, climate change will worsen the uneven distribution of water resources in China. Outstanding rises in temperature would exacerbate evapotranspiration, intensifying the risk of water shortage for agricultural production in the North. Although China's southern region has an abundance of rainfall, most of its water is lost due to flooding. As the Chinese government faces challenges managing its expanding population, increased demand for water to support the nation's economic activity and people will burden the government. In essence, a water shortage is indeed a large concern for the country.

Overfishing and rising ocean temperatures are killing the coral reefs in the South China Sea.  This lowers biodiversity, and negatively affects the fish market economy in China.

Impacts on people

At least 72% of Chinese, American and European respondents to a 2020−2021 European Investment Bank climate survey stated that climate change had an impact on everyday life.

Health impacts

Climate change has a significant impact on the health of Chinese people. The high temperature has caused health risks for some groups of people, such as older people (≥65 years old), outdoor workers, or people living in poverty. In 2019, each person who is older than 65 years had to endure extra 13 days of the heatwave, and 26,800 people died because of the heatwave in 2019.

In the future, the probability rate of malaria transmission will increase 39-140 percent if the temperature increase of 1-2 degrees Celsius in south China.

Economic impacts

According to the IPCC Sixth Assessment Report the country that will pay the highest financial cost if the temperature continue to rise is China. The impacts will include food insecurity, water scarcity, flooding, especially in coastal areas where most of the population lives due to higher than average sea level rise, and more powerful cyclones. At some point part of the country can face wet-bulb temperatures higher than humans and other mammals can tolerate more than six hours.

Agriculture

The negative effects on China's agriculture caused by climate change have appeared. There was an increase in agricultural production instability, severe damages caused by high temperature and drought, and lower production and quality in the prairie. In the near future, climate change may cause negative influences, causing a reduction of output in wheat, rice, and corn, and change the agricultural distribution of production. China is also dealing with agricultural issues due global demands of products such as soybeans. This global demand is causing coupled effects that stretch across oceans which in turn is affecting other countries. Environmental factor#Socioeconomic Drivers

Fishing Industry

Due to overfishing, pollution, global temperature increase, and change in pH to the world's oceans, the South China Sea is suffering from a lack in biodiversity among marine life. Historically, China was the world's largest capture fisheries and aquaculture producer, making the fish market a significant part of the Chinese economy. Due to the environmental impacts, coral reefs in the South China Sea are dying, decreasing the amount of marine life in the South China Sea. Fisheries are not able to catch the amount of fish that was once brought to the fish market, making that part of the economy suffer. The amount of fishing in China is unsustainable, and therefore declining. The fishing industry supplies a significant amount of jobs, exports, and domestic consumption, which will disappear if the fishing industry collapses.

Mitigation and adaptation

In general, the climate policy of China can be described as "underpromise so that it can overdeliver". China sets itself low climate targets that cannot surely prevent a 2 degrees temperature rise, but it mostly achieves and even overachieve its targets. China wants to peak its carbon emissions before 2030 and became carbon neutral by 2070. The president of China declared that his country will stop financing coal power plants abroad. China achieved 9 of its 15 climate targets in the Paris agreement before it was planned to happen. The climate policy of China can become more effective as a result of higher climate ambition of other countries and better cooperation with the USA. In March 2022 China increased its fossil fuel production "amid “growing” fears of global energy shortages and “rising” concerns of an economic slump"

Mitigation approaches

Main article: Greenhouse gas emissions by China § Mitigation

In 2022, China issued its climate targets in the 14th Five-Year Plan. Those include:

Reduce the economy's energy intensity by 13.5%.

Reduce the CO2 intensity of the economy by 18%.

Increase in the share of nonfossil energy to about 20%.

All three targets should be achieved by 2025. The change is in comparison to the numbers for the year 2021.

In the beginning of the year 2022 a government-supported research said China will peak CO2 emissions in the year 2027 at 12.2Gt and reach net zero carbon emissions before 2060 if it will change its development model.

Renewable energy

Ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese government since 1949. The country is the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO₂ emissions per unit of GDP by 20%. On a per-capita basis, it was the world's 51st largest emitter of greenhouse gases in 2016.

China is the world's leading country in electricity production from renewable energy sources, with over triple the generation of the second-ranking country, the United States. 

China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity, and is expected to contribute 43 percent of global renewable capacity growth. China's total renewable energy capacity exceeded 1,000GW in 2021, accounting for 43.5 per cent of the country's total power generation capacity, 10.2 percentage points higher than in 2015. The country aims to have 80 per cent of its total energy mix come from non-fossil fuel sources by 2060, and achieve a combined 1,200GW of solar and wind capacity by 2030.

Energy efficiency

A 2011 report by a project facilitated by World Resources Institute stated that the 11th five-year plan (2005 to 2010), in response to worsening energy intensity in the 2002-2005 period, set a goal of a 20% improvement of energy intensity. The report stated that this goal likely was achieved or nearly achieved. The next five-year plan set a goal of improving energy intensity by 16%. In 2022 China published a plan of energy conservation for the 14th five-year plan (2021 to 2025) with a target of cutting energy consumption per unit of GDP by 13.5% by the year 2025 in comparison to the level of 2020. The plan regards 17 different sectors in the economy. In some sectors 20% - 40% of the capacities are not meeting the standards they need to meet by 2025. This policy expects to benefit the biggest companies who have the possibility to reach the targets.

==== Mitigation examples during the provinces of China, there are various projects held aiming to solve emissions reduction and energy-saving, which is a big step in tackling climate change. Beijing is developing in replacing traditional bulbs with energy-saving light bulbs. Provinces such as Rizhao and Dezhou are promoting solar energy in the building heating system. Besides, Tsinghua University launched a lead on low-carbon city development. The city is currently working with Tsinghua University to improve the urban environment by introducing renewable energy into industries and households. More than 360 Chinese cities have dockless bike-sharing systems that deploy nearly 20 million bicycles that travel an average of 47 million kilometres per day. According to the World Resources Institute report, dockless bike-sharing systems reduced China's GHG emissions by 4.8 million tonnes of CO2 annually.

Adaptation approaches

Pictured here is the conversion of three large rivers in Ningbo, China. The country is taking substantial measures to combat the flash floods predicted to intensify in the future.

China has experienced a seven-fold increase in the frequency of floods since the 1950s, rising every decade. The frequency of extreme rainfall has increased and is predicted to continue to increase in the western and southern parts of China. The country is currently undertaking efforts to reduce the threat of these floods (which have the potential effect of completely destroying vulnerable communities), largely focusing on improving the infrastructure responsible for tracking and maintaining adequate water levels. That being said, the country is promoting the extension of technologies for water allocation and water-saving mechanisms. In the country's National Climate Change Policy Program, one of the goals specifically set out is to enhance the ability to bear the impacts of climate change, as well as to raise the public awareness on climate change. China's National Climate Change Policy states that it will integrate climate change policies into the national development strategy. In China, this national policy comes in the form of its "Five Year Plans for Economic and Social Development". China's Five Year Plans serve as the strategic road maps for the country's development. The goals spelled out in the Five Year Plans are mandatory as government officials are held responsible for meeting the targets.

Policies and legislation

Climate change has not been a priority to China until recently (around 2008), when this issue was brought to a higher platform. Chinese state affairs operate as a central system, not a federal system. For example, the central government makes decisions and the local governments fulfill them. As a result, the local governments receive constraints and are measured by their performance from the central governments. Solving environmental issues such as climate change requires long-term investments in money, resources, and time. It is believed that these efforts will be detrimental to economic growth, which is of particular importance to the promotion of local government executives. This is why local governments have no engagement in addressing this issue.

In China's first NDC submission, key areas were identified for climate change adaptation, including agriculture, water resources, and vulnerable areas. It also mentioned that an adaptation strategy should be implemented through regional strategies. Flooding in cities is being tackled by collecting and recycling rainwater. In 2013, China issued its National Strategy for Climate Change Adaptation and set goals of reducing vulnerability, strengthening monitoring, and raising public awareness. Efforts on implementation have been put in adapting forestry, meteorological management, infrastructure, and risk planning.

The development of technology and economy in China share more responsibility in tackling climate change. After facing the 2011 smog issue, China's government launched an extensive strategy, which is to improve air quality by reducing the growth of coal consumption. Nevertheless, the trade war that involved China as one of the leading participants has resulted in the loss of control of polluting industries, especially in the steel and cement during 2018. Fortunately, nearly 70 multinational and local brands implemented the monitoring data by The Institute of Public & Environmental Affairs (IPE) in China, stimulating nearly 8,000 suppliers approaching regulatory violations.

Paris agreement

The Paris agreement is a legally binding international agreement. Its main goal is to limit global warming to below 1.5 degrees Celsius, compared to pre-industrial levels. The Nationally Determined Contributions (NDCs) are the plans to fight climate change adapted for each country, which outlines specific goals and targets for the upcoming five years to help mitigate the effects of climate change. Every party in the agreement has different targets based on its own historical climate records and country's circumstances and all the targets for each country are stated in their NDC.

China is currently a member of the United Nations Framework Convention on Climate Change, the Paris Agreement. As a part of this agreement it has agreed to the 2016 Nationally Determined Contributions (NDC).

The NDC target regarding the China against climate change and greenhouse gas emissions under the Paris agreement are the following:

• Peak of carbon dioxide emissions around 2030.
• 60% to 65% reduction of Carbon dioxide emission per unit of its gross domestic product (GDP), compared to 2005.
• Increase the forest stock volume by around 4.5 billion cubic meters on the 2005 level.

In the NDC of China there is a list of things that have been achieved by 2014:

• Proactive approach to climate change (for example enhancing mechanisms to effectively defend key areas).

Progress

Climate action tracker (CAT) is an independent scientific analysis that tracks government climate action and measures it against the globally agreed Paris Agreement. Climate action tracker found China actions to be "Highly insufficient".

National carbon trading scheme

The Chinese national carbon trading scheme is an intensity-based trading system for carbon dioxide emissions by China, which started operating in 2021. This emission trading scheme (ETS) creates a carbon market where emitters can buy and sell emission credits. From this scheme, China can limit emissions, but allow economic freedom for emitters to reduce emissions or purchase emission allowances from other emitters. China is the largest emitter of greenhouse gases (GHG) and many major Chinese cities have severe air pollution. The scheme is run by the Ministry of Ecology and Environment, which eventually plans to limit emissions from six of China's top carbon dioxide emitting industries. In 2021 it started with its power plants, and covers 40% of China's emissions, which is 15% of world emissions. China was able to gain experience in drafting and implementation of an ETS plan from the United Nations Framework Convention on Climate Change (UNFCCC), where China was part of the Clean Development Mechanism (CDM). From this experience with carbon markets, and lengthy discussions with the next largest carbon market, the European Union (EU), as well as analysis of small scale pilot markets in major Chinese cities and provinces, China's national ETS is the largest of its kind and will help China achieve its Nationally Determined Contribution (NDC) to the Paris Agreement. In July 2021 permits were being handed out for free rather than auctioned, and the market price per tonne of CO2e was around RMB 50, far less than the EU ETS and the UK ETS.

International cooperation

Main article: Debate over China's economic responsibilities for climate change mitigation

Attitudes of the Chinese government on climate change, specifically regarding the role of China in climate change action, have shifted notably in recent years. Historically, climate change was largely seen as a problem that has been created by and should be solved by industrialized countries; in 2015, China said it supports the "common but differentiated responsibilities" principle, which holds that since China is still developing, its abilities and capacities to reduce emissions are comparatively lower than developed countries', but China became the world's largest emitter of carbon dioxide in 2006 and is now responsible for more than a quarter of the world's overall greenhouse gas emissions. 

In 2018, the government has urged countries to continue to support the Paris agreement, even in the wake of the United States' withdrawal in 2017. In 2020, Chinese leader Xi Jinping announced at the UN General Assembly in New York that his country will end its contribution to global heating and achieve carbon neutrality by 2060 by adopting “more vigorous policies and measures.”

Both internationally and within the People's Republic of China, there has been an ongoing debate over China's economic responsibilities for climate change mitigation. The argument has been made that China has a crucial role to play in keeping global warming under 2 °C, and that this cannot be accomplished unless coal use, which accounts for the majority of China's emissions, falls sharply. President Xi says China will "phase down" coal use from 2026 - and will not build new coal-fired projects abroad - but some governments and campaigners say the plans are not going far enough.

The People's Republic of China is an active participant in the climate change talks and other multilateral environmental negotiations, and claims to take environmental challenges seriously but is pushing for the developed world to help developing countries to a greater extent.

However the Belt and Road Initiative is constructing coal-fired power stations (for example Emba Hunutlu power station in Turkey) thus increasing greenhouse gas emissions from other countries.

China is a part of the United Nations Framework Convention on Climate Change, BASIC Alliance.  This alliance is an international commitment to work in partnership with Brazil, South Africa, and India. BASIC’s international commitments and goals are to be carbon net-zero before 2060, and to help achieve the global goal from the UNFCCC of reducing emissions to 1.5% degrees celsius before pre-industrial levels. In 2021, at the UN General Assembly, Chinese leader Xi Jinping stated that China will no longer fund coal-fired power plants abroad. Xi also repeated the country’s commitment to achieving carbon neutrality by 2060.

Society and culture

Public opinion

According to a study from 2017 conducted by the China Climate Change Communication program, 94% of interviewees supported fulfilling the Paris agreement, 96.8% of interviewees supported international cooperation on global climate change, and more than 70% of interviewees were willing to purchase products environmentally friendly . 98.7% of interviewees supported implementing climate change education at schools. Respondents were most concerned about the air pollution caused by climate change. The investigation included 4025 samples.

The investigation showed that Chinese citizens agreed that they were experiencing climate change and that it was caused by human activities.

Furthermore, most Chinese citizens believe individual action on climate change can help, although the government is still seen as the entity most responsible for dealing with climate change. If the government does take action, fiscal and taxation policies are seen as potentially effective.

Activism

Calculations in 2021 showed that for giving the world a 50% chance of avoiding a temperature rise of 2 degrees or more China should increase its climate commitments by 7%. For a 95% chance it should increase the commitments by 24%. For giving a 50% chance of staying below 1.5 degrees China should increase its commitments by 41%.

Activists such as Howey Ou have done school strikes for climate.

Lunar eclipse

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Lunar_eclipse 

Totality during the lunar eclipse of 21 January 2019. Direct sunlight is being blocked by the Earth, and the only light reaching it is sunlight refracted by Earth's atmosphere, producing a reddish color.

 

Latter phases of the partial lunar eclipse on 17 July 2019 taken from Gloucestershire, United Kingdom

A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit.

The reddish color of totally eclipsed Moon is caused by Earth completely blocking direct sunlight from reaching the Moon, with the only light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish for the same reason that a sunset or sunrise does: the Rayleigh scattering of blue light.

Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, because the Moon's shadow is smaller. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are dimmer than the full Moon.

For the date of the next eclipse, see § Recent and forthcoming lunar eclipses.

Types of lunar eclipse

A schematic diagram of the shadow cast by Earth. Within the umbra, the central region, the planet totally shields direct sunlight. In contrast, within the penumbra, the outer portion, the sunlight is only partially blocked. (Neither the Sun, Moon, and Earth sizes nor the distances between the bodies are to scale.)

 

A total penumbral lunar eclipse dims the Moon in direct proportion to the area of the Sun's disk covered by Earth. This comparison of the Moon (within the southern part of Earth's shadow) during the penumbral lunar eclipse of January 1999 (left) and the Moon outside the shadow (right) shows this slight darkening.

Earth's shadow can be divided into two distinctive parts: the umbra and penumbra. Earth totally occludes direct solar radiation within the umbra, the central region of the shadow. However, since the Sun's diameter appears about one-quarter of Earth's in the lunar sky, the planet only partially blocks direct sunlight within the penumbra, the outer portion of the shadow.

Penumbral lunar eclipse

This occurs when the Moon passes through Earth's penumbra. The penumbra causes a subtle dimming of the lunar surface, which is only visible to the naked eye when about 70% of the Moon's diameter has immersed into Earth's penumbra. A special type of penumbral eclipse is a total penumbral lunar eclipse, during which the Moon lies exclusively within Earth's penumbra. Total penumbral eclipses are rare, and when these occur, the portion of the Moon closest to the umbra may appear slightly darker than the rest of the lunar disk.

Partial lunar eclipse

This occurs when only a portion of the Moon enters Earth's umbra, while a total lunar eclipse occurs when the entire Moon enters the planet's umbra. The Moon's average orbital speed is about 1.03 km/s (2,300 mph), or a little more than its diameter per hour, so totality may last up to nearly 107 minutes. Nevertheless, the total time between the first and the last contacts of the Moon's limb with Earth's shadow is much longer and could last up to 236 minutes.

Total lunar eclipse

This occurs when the moon falls entirely within the earth's umbra. Just prior to complete entry, the brightness of the lunar limb-- the curved edge of the moon still being hit by direct sunlight-- will cause the rest of the moon to appear comparatively dim. The moment the moon enters a complete eclipse, the entire surface will become more or less uniformly bright. Later, as the moon's opposite limb is struck by sunlight, the overall disk will again become obscured. This is because as viewed from the Earth, the brightness of a lunar limb is generally greater than that of the rest of the surface due to reflections from the many surface irregularities within the limb: sunlight striking these irregularities is always reflected back in greater quantities than that striking more central parts, and is why the edges of full moons generally appear brighter than the rest of the lunar surface. This is similar to the effect of velvet fabric over a convex curved surface which to an observer will appear darkest at the center of the curve. It will be true of any planetary body with little or no atmosphere and an irregular cratered surface (e.g., Mercury) when viewed opposite the Sun.

Central lunar eclipse

This is a total lunar eclipse during which the Moon passes through the centre of Earth's shadow, contacting the antisolar point. This type of lunar eclipse is relatively rare.

The relative distance of the Moon from Earth at the time of an eclipse can affect the eclipse's duration. In particular, when the Moon is near apogee, the farthest point from Earth in its orbit, its orbital speed is the slowest. The diameter of Earth's umbra does not decrease appreciably within the changes in the Moon's orbital distance. Thus, the concurrence of a totally eclipsed Moon near apogee will lengthen the duration of totality.

Selenelion

A view of the October 2014 lunar eclipse from Minneapolis, with the setting and partially eclipsed Moon appearing squashed just above the horizon just after sunrise (seen as sunlight shining on the tree in the right image)

A selenelion or selenehelion, also called a horizontal eclipse, occurs where and when both the Sun and an eclipsed Moon can be observed at the same time. The event can only be observed just before sunset or just after sunrise, when both bodies will appear just above opposite horizons at nearly opposite points in the sky. A selenelion occurs during every total lunar eclipse-- it is an experience of the observer, not a planetary event separate from the lunar eclipse itself. Typically, observers on Earth located on high mountain ridges undergoing false sunrise or false sunset at the same moment of a total lunar eclipse will be able to experience it. Although during selenelion the Moon is completely within the Earth's umbra, both it and the Sun can be observed in the sky because atmospheric refraction causes each body to appear higher (i.e., more central) in the sky than its true geometric planetary position.

Timing

As viewed from Earth, the Earth's shadow can be imagined as two concentric circles. As the diagram illustrates, the type of lunar eclipse is defined by the path taken by the Moon as it passes through Earth's shadow. If the Moon passes through the outer circle but does not reach the inner circle, it is a penumbral eclipse; if only a portion of the moon passes through the inner circle, it is a partial eclipse; and if entire Moon passes through the inner circle at some point, it is a total eclipse.

 

Contact points relative to the Earth's umbral and penumbral shadows, here with the Moon near is descending node

The timing of total lunar eclipses is determined by what are known as its "contacts" (moments of contact with Earth's shadow):

P1 (First contact): Beginning of the penumbral eclipse. Earth's penumbra touches the Moon's outer limb.

U1 (Second contact): Beginning of the partial eclipse. Earth's umbra touches the Moon's outer limb.

U2 (Third contact): Beginning of the total eclipse. The Moon's surface is entirely within Earth's umbra.

Greatest eclipse: The peak stage of the total eclipse. The Moon is at its closest to the center of Earth's umbra.

U3 (Fourth contact): End of the total eclipse. The Moon's outer limb exits Earth's umbra.

U4 (Fifth contact): End of the partial eclipse. Earth's umbra leaves the Moon's surface.

P4 (Sixth contact): End of the penumbral eclipse. Earth's penumbra no longer makes contact with the Moon.

Danjon scale

The following scale (the Danjon scale) was devised by André Danjon for rating the overall darkness of lunar eclipses:

L = 0: Very dark eclipse. Moon almost invisible, especially at mid-totality.

L = 1: Dark eclipse, gray or brownish in coloration. Details distinguishable only with difficulty.

L = 2: Deep red or rust-colored eclipse. Very dark central shadow, while outer edge of umbra is relatively bright.

L = 3: Brick-red eclipse. Umbral shadow usually has a bright or yellow rim.

L = 4: Very bright copper-red or orange eclipse. Umbral shadow is bluish and has a very bright rim.

Lunar versus solar eclipse

A solar eclipse occurs in the daytime at new moon, when the Moon is between Earth and the Sun, while a lunar eclipse occurs at night at full moon, when Earth passes between the Sun and the Moon.

 

The Moon does not completely darken as it passes through the umbra because Earth's atmosphere refracts sunlight into the shadow cone.

There is often confusion between a solar eclipse and a lunar eclipse. While both involve interactions between the Sun, Earth, and the Moon, they are very different in their interactions.

Lunar eclipse appearance

In a lunar eclipse, the Moon often passes through two regions of Earth's shadow: an outer penumbra, where direct sunlight is dimmed, and an inner umbra, where indirect and much dimmer sunlight refracted by Earth's atmosphere shines on the Moon, leaving a reddish color. This can be seen in different exposures of a partial lunar eclipse, for example here with exposures of 1/80, 2/5, and 2 seconds.

The Moon does not completely darken as it passes through the umbra because of the refraction of sunlight by Earth's atmosphere into the shadow cone; if Earth had no atmosphere, the Moon would be completely dark during the eclipse. The reddish coloration arises because sunlight reaching the Moon must pass through a long and dense layer of Earth's atmosphere, where it is scattered. Shorter wavelengths are more likely to be scattered by the air molecules and small particles; thus, the longer wavelengths predominate by the time the light rays have penetrated the atmosphere. Human vision perceives this resulting light as red. This is the same effect that causes sunsets and sunrises to turn the sky a reddish color. An alternative way of conceiving this scenario is to realize that, as viewed from the Moon, the Sun would appear to be setting (or rising) behind Earth.

From the Moon, a lunar eclipse would show a ring of reddish-orange light surrounding a silhouetted Earth in the lunar sky.

The amount of refracted light depends on the amount of dust or clouds in the atmosphere; this also controls how much light is scattered. In general, the dustier the atmosphere, the more that other wavelengths of light will be removed (compared to red light), leaving the resulting light a deeper red color. This causes the resulting coppery-red hue of the Moon to vary from one eclipse to the next. Volcanoes are notable for expelling large quantities of dust into the atmosphere, and a large eruption shortly before an eclipse can have a large effect on the resulting color.

Christopher Columbus predicting a lunar eclipse.

Lunar eclipse in culture

Several cultures have myths related to lunar eclipses or allude to the lunar eclipse as being a good or bad omen. The Egyptians saw the eclipse as a sow swallowing the Moon for a short time; other cultures view the eclipse as the Moon being swallowed by other animals, such as a jaguar in Mayan tradition, or a mythical three-legged toad known as Chan Chu in China. Some societies thought it was a demon swallowing the Moon, and that they could chase it away by throwing stones and curses at it. The Ancient Greeks correctly believed the Earth was round and used the shadow from the lunar eclipse as evidence. Some Hindus believe in the importance of bathing in the Ganges River following an eclipse because it will help to achieve salvation.

Inca

Similarly to the Mayans, the Incans believed that lunar eclipses occurred when a jaguar ate the Moon, which is why a blood moon looks red. The Incans also believed that once the jaguar finished eating the Moon, it could come down and devour all the animals on Earth, so they would take spears and shout at the Moon to keep it away.

Mesopotamians

The ancient Mesopotamians believed that a lunar eclipse was when the Moon was being attacked by seven demons. This attack was more than just one on the Moon, however, for the Mesopotamians linked what happened in the sky with what happened on the land, and because the king of Mesopotamia represented the land, the seven demons were thought to be also attacking the king. In order to prevent this attack on the king, the Mesopotamians made someone pretend to be the king so they would be attacked instead of the true king. After the lunar eclipse was over, the substitute king was made to disappear (possibly by poisoning).

Chinese

In some Chinese cultures, people would ring bells to prevent a dragon or other wild animals from biting the Moon. In the 19th century, during a lunar eclipse, the Chinese navy fired its artillery because of this belief. During the Zhou Dynasty (c. 1046–256 BC) in the Book of Songs, the sight of a Red Moon engulfed in darkness was believed to foreshadow famine or disease.

Change to reddish cast

Certain lunar eclipses have been referred to as "blood moons" in popular articles but this is not a scientifically-recognized term. This term has been given two separate, but overlapping, meanings.

The first, and simpler, meaning relates to the reddish color a totally eclipsed Moon takes on to observers on Earth. As sunlight penetrates the atmosphere of Earth, the gaseous layer filters and refracts the rays in such a way that the green to violet wavelengths on the visible spectrum scatter more strongly than the red, thus giving the Moon a reddish cast.

The second meaning of "blood moon" has been derived from this apparent coloration by two fundamentalist Christian pastors, Mark Blitz and John Hagee. They claimed that the 2014–15 "lunar tetrad" of four lunar eclipses coinciding with the feasts of Passover and Tabernacles matched the "moon turning to blood" described in the Book of Joel of the Hebrew Bible. This tetrad was claimed to herald the Second Coming of Christ and the Rapture as described in the Book of Revelation on the date of the first of the eclipses in this sequence on April 15, 2014.

At least two lunar eclipses and as many as five occur every year, although total lunar eclipses are significantly less common. If the date and time of an eclipse is known, the occurrences of upcoming eclipses are predictable using an eclipse cycle, like the saros.

Eclipses occur only during an eclipse season, when the Sun appears to pass near either node of the Moon's orbit.
