Siegfried Fred Singer (born September 27, 1924) is an Austrian-born American physicist and emeritus professor of environmental science at the University of Virginia. Singer trained as an atmospheric physicist and is known for his work in space research, atmospheric pollution, rocket and satellite technology, his questioning of the link between UV-B and melanoma rates, and that between chlorofluoro compounds and stratospheric ozone loss, his public downplaying of the health risks of passive smoking, and as an advocate for climate change denial. He is the author or editor of several books including Global Effects of Environmental Pollution (1970), The Ocean in Human Affairs (1989), Global Climate Change (1989), The Greenhouse Debate Continued (1992), and Hot Talk, Cold Science (1997). He has also co-authored Unstoppable Global Warming: Every 1,500 Years (2007) with Dennis Avery, and Climate Change Reconsidered (2009) with Craig Idso.

Singer has had a varied career, serving in the armed forces, government, and academia. He designed mines for the U.S. Navy during World War II, before obtaining his Ph.D. in physics from Princeton University in 1948 and working as a scientific liaison officer in the U.S. Embassy in London. He became a leading figure in early space research, was involved in the development of earth observation satellites, and in 1962 established the National Weather Bureau's Satellite Service Center. He was the founding dean of the University of Miami School of Environmental and Planetary Sciences in 1964, and held several government positions, including deputy assistant administrator for the Environmental Protection Agency, and chief scientist for the Department of Transportation. He held a professorship with the University of Virginia from 1971 until 1994, and with George Mason University until 2000.

In 1990 Singer founded the Science & Environmental Policy Project, and in 2006 was named by the Canadian Broadcasting Corporation as one of a minority of scientists said to be creating a stand-off on a consensus on climate change. Singer argues there is no evidence that global warming is attributable to human-caused increases in atmospheric carbon dioxide, and that humanity would benefit if temperatures do rise. He is an opponent of the Kyoto Protocol, and has claimed that climate models are neither based on reality nor evidence. Singer has been accused of rejecting peer-reviewed and independently confirmed scientific evidence in his claims concerning public health and environmental issues.

Early life and education

Singer was born in Vienna, Austria, to a Jewish family, where his father was a jeweler and his mother a homemaker. When the Nazis invaded, the family fled, Singer leaving on a children's transport train with other Jewish children. He ended up in England, where he lived in Northumberland, working for a time as a teenage optician. Several years later he emigrated to Ohio and became an American citizen in 1944. He received a B.E.E. in electrical engineering from Ohio State University in 1943, and an A.M. in physics from Princeton in 1944. He taught physics at Princeton while he worked on his masters and his doctorate, obtaining his Ph.D. there in 1948. His doctoral thesis was titled, "The density spectrum and latitude dependence of extensive cosmic ray air showers." His supervisor was John Archibald Wheeler, and his thesis committee included J. Robert Oppenheimer and Niels Bohr.

Career

1950: United States Navy

After his masters, Singer joined the Armed Forces, working for the United States Navy on mine warfare and countermeasures from 1944 until 1946. While with the Naval Ordnance Laboratory he developed an arithmetic element for an electronic digital calculator that he called an "electronic brain". He was discharged in 1946 and joined the Upper Atmosphere Rocket Program at the Johns Hopkins University Applied Physics Laboratory in Silver Spring, Maryland, working there until 1950. He focused on ozone, cosmic rays, and the ionosphere, all measured using balloons and rockets launched from White Sands, New Mexico, or from ships out at sea. Rachel White Scheuering writes that for one mission to launch a rocket, he sailed with a naval operation to the Arctic, and also conducted rocket launching from ships at the equator.

From 1950 to 1953, he was attached to the U.S. Embassy in London as a scientific liaison officer with the Office of Naval Research, where he studied research programs in Europe into cosmic radiation and nuclear physics. While there, he was one of eight delegates with a background in guided weapons projects to address the Fourth International Congress of Astronautics in Zurich in August 1953, at a time when, as The New York Times reported, most scientists saw space flight as thinly disguised science fiction.

1951: Design of early satellites

Singer's MOUSE satellite, which he designed in the early 1950s.
 
Singer was one of the first scientists to urge the launching of earth satellites for scientific observation during the 1950s. In 1951 or 1952 he proposed the MOUSE ("Minimal Orbital Unmanned Satellite, Earth"), a 100 pounds (45 kg) satellite that would contain Geiger counters for measuring cosmic rays, photo cells for scanning the Earth, telemetry electronics for sending data back to Earth, a magnetic data storage device, and rudimentary solar energy cells. Although MOUSE never flew, the Baltimore News Post reported in 1957 that had Singer's arguments about the need for satellites been heeded, the U.S. could have beaten Russia by launching the first earth satellite. He also proposed (along with R. C. Wentworth) that satellite measurement of ultraviolet backscatter could be used as a method to measure atmospheric ozone profiles. This technique was later used on early weather satellites.

1953: University of Maryland

Singer moved back to the United States in 1953, where he took up an associate professorship in physics at the University of Maryland, and at the same time served as the director of the Center for Atmospheric and Space Physics. Scheuering writes that his work involved conducting experiments on rockets and satellites, remote sensing, radiation belts, the magnetosphere, and meteorites. He developed a new method of launching rockets into space: firing them from a high-flying plane, both with and without a pilot. The Navy adopted the idea and Singer supervised the project. He received a White House Special Commendation from President Eisenhower in 1954 for his work.

He became one of 12 board members of the American Astronautical Society, an organization formed in 1954 to represent the country's 300 leading scientists and engineers in the area of guided missiles—he was one of seven members of the board to resign in December 1956 after a series of disputes about the direction and control of the group.

In November 1957 Singer and other scientists at the university successfully designed and fired three new "Oriole" rockets off the Virginia Capes. The rockets weighed less than 25 pounds (11 kg) and could be built for around $2000. Fired from a converted Navy LSM, they could reach an altitude of 50,000 feet (15,000 m) and had a complete telemetry system to send back information on cosmic, ultraviolet and X-rays. Singer said that the firings placed "the exploration of outer space with high altitude rockets on the same basis, cost-wise and effort-wise, as low atmosphere measurements with weather balloons. From now on, we can fire thousands of these rockets all over the world with very little cost."

In February 1958, when he was head of the cosmic ray group of the University of Maryland's physics department, he was congratulated in a telegram to the president of the university from President Eisenhower for his work in satellite research. In April 1958, he was appointed as a consultant to the House Committee on Astronautics and Space Exploration, which was preparing to hold hearings on President Eisenhower's proposal for a new agency to handle space research, and a month later received the Ohio State University's Distinguished Alumnus Award. He became a full professor at Maryland in 1959, and was chosen that year by the United States Junior Chamber of Commerce as one of the country's ten outstanding young men.

In a January 1960 presentation to the American Physical Society, Singer sketched out his vision of what the environment around the earth might consist of, extending up to 40,000 miles (64,000 km) into space. He became known for his early predictions about the properties of the electrical particles trapped around the earth, which were partly verified by later discoveries in satellite experiments. In December 1960, he suggested the existence of a shell of visible dust particles around the earth some 600 to 1,000 miles (1,600 km) in space, beyond which there was a layer of smaller particles, a micrometre or less in diameter, extending 2,000 to 4,000 miles (6,400 km). In March 1961 Singer and another University of Maryland physicist, E. J. Opik, were given a $97,000 grant by NASA to conduct a three-year study of interplanetary gas and dust.

1960: Artificial Phobos hypothesis

In a 1960 Astronautics newsletter, Singer commented on Iosif Shklovsky's hypothesis that the orbit of the Martian moon Phobos suggests that it is hollow, which implies it is of artificial origin. Singer wrote: "My conclusion there is, and here I back Shklovsky, that if the satellite is indeed spiraling inward as deduced from astronomical observation, then there is little alternative to the hypothesis that it is hollow and therefore martian made. The big 'if' lies in the astronomical observations; they may well be in error. Since they are based on several independent sets of measurements taken decades apart by different observers with different instruments, systematic errors may have influenced them." Later measurements confirmed Singer's big "if" caveat: Shklovsky overestimated Phobos' rate of altitude loss due to bad early data. Photographs by probes beginning in 1972 show a natural stony surface with craters. Ufologists continue to present Singer as an unconditional supporter of Shklovsky's artificial Phobos hypothesis.

Time magazine wrote in 1969 that Singer had had a lifelong fascination with Phobos and Mars's second moon, Deimos. He told Time it might be possible to pull Deimos into the Earth's orbit so it could be examined. During an international space symposium in May 1966, attended by space scientists from the United States and Soviet Union, he first proposed that manned landings on the Martian moons would be a logical step after a manned landing on the Earth's moon. He pointed out that the very small sizes of Phobos and Deimos—approximately 14 miles (23 km) and eight miles (13 km) in diameter and sub milli-g surface gravity—would make it easier for a spacecraft to land and take off again.

1962: National Weather Center and University of Miami

In 1962, on leave from the university, Singer was named as the first director of meteorological satellite services for the National Weather Satellite Center, now part of the National Oceanic and Atmospheric Administration, and directed a program for using satellites to forecast the weather. He stayed there until 1964. He told Time magazine in 1969 that he enjoyed moving around. "Each move gave me a completely new perspective," he said. "If I had sat still, I'd probably still be measuring cosmic rays, the subject of my thesis at Princeton. That's what happens to most scientists." When he stepped down as director he received a Department of Commerce Gold Medal Award for Distinguished Federal Service.

In 1964, he became the first dean of the School of Environmental and Planetary Sciences at the University of Miami in 1964, the first school of its kind in the country, dedicated to space-age research. In December 1965, The New York Times reported on a conference Singer hosted in Miami Beach during which five groups of scientists, working independently, presented research identifying what they believed was the remains of a primordial flash that occurred when the universe was born.

1967: Department of Interior and EPA

In 1967 he accepted the position of deputy assistant secretary with the U.S. Department of the Interior, where he was in charge of water quality and research. When the U.S. Environmental Protection Agency was created on 1970, he became its deputy assistant administrator of policy.

1971–1994 University of Virginia

Singer accepted a professorship in Environmental Sciences at the University of Virginia in 1971, a position he held until 1994, where he taught classes on environmental issues such as ozone depletion, acid rain, climate change, population growth, and public policy issues related to oil and energy. In 1987 he took up a two-year post as chief scientist at the Department of Transportation, and in 1989 joined the Institute of Space Science and Technology in Gainesville, Florida where he contributed to a paper on the results from the Interplanetary Dust Experiment using data from the Long Duration Exposure Facility satellite. When he retired from Virginia in 1994, he became Distinguished Research Professor at the Institute for Humane Studies at George Mason University until 2000.

Naomi Oreskes and Erik Conway say that Singer was involved in the Reagan administration's efforts to prevent regulatory action to reduce acid rain.

Consultancies

Singer has worked as a consultant for several government agencies, including the House Select Committee on Space, NASA, the Government Accountability Office, the National Science Foundation, the United States Atomic Energy Commission, National Research Council, the Department of Defense Strategic Defense Initiative, Department of Energy Nuclear Waste Panel, and the Department of the Treasury. Other clients have included the states of Virginia, Alaska, and Pennsylvania. In the private sector he has worked for Mitre Corporation, General Electric, Ford, General Motors; during the late 1970s Singer consulted with Exxon, Shell, Unocal Sun Oil, and ARCO; and Lockheed Martin, Martin–Marietta, McDonnell Douglas, ANSER, and IBM on space research. He has also advised the Independent Institute, the American Council on Science and Health, and the Frontiers of Freedom Institute.

Public debates

Writing

Throughout his academic career Singer has written frequently in the mainstream press, including The New York Times, The Washington Post, and Wall Street Journal, often striking up positions disputing mainstream thinking. His overall position is one of distrust of federal regulations and a strong belief in the efficacy of the free market. He believes in what Rachel White Scheuering calls "free market environmentalism": that market principles and incentives should be sufficient to lead to the protection of the environment and conservation of resources. Regular themes in his articles have been energy, oil embargoes, OPEC, Iran, and rising prices. Throughout the 1970s, for example, he downplayed the idea of an energy crisis and said it was largely a media event. In several papers in the 1990s and 2000s he struck up other positions against the mainstream, questioning the link between UV-B and melanoma rates, and that between CFCs and stratospheric ozone loss.

In October 1967, Singer wrote an article for The Washington Post from the perspective of 2007. His predictions included that planets had been explored but not colonized, and although rockets had become more powerful they had not replaced aircraft and ramjet vehicles. None of the fundamental laws of physics had been overturned. There was increased reliance on the electronic computer and data processor; the most exciting development was the increase in human intellect by direct electronic storage of information in the brain—the coupling of the brain to an external computer, thereby gaining direct access to an information library.

He debated the astronomer Carl Sagan on ABC's Nightline, regarding the possible environmental effects of the Kuwaiti oil fires. Sagan argued that if enough fire-fighting teams were not assembled in short order, and if many fires were left to burn over a period of months to possibly a year, the smoke might loft into the upper atmosphere and lead to massive agricultural failures over South Asia. Singer argued that it would rise to 3,000 feet (910 m) then be rained out after a few days. In fact, both Sagan and Singer were incorrect; smoke plumes from the fires rose to 10,000–12,000 feet and lingered for nearly a month, but despite absorbing 75–80% of the sun's radiation in the Persian Gulf area the plumes had little global effect.

The public debates in which Singer has received most criticism have been about second-hand smoke and global warming. He has questioned the link between second-hand smoke and lung cancer, and has been an outspoken opponent of the mainstream scientific view on climate change; he argues there is no evidence that increases in carbon dioxide produced by human beings is causing global warming and that the temperature of the earth has always varied. A CBC Fifth Estate documentary in 2006 linked these two debates, naming Singer as a scientist who has acted as a consultant to industry in both areas, either directly or through a public relations firm. Naomi Oreskes and Erik Conway named Singer in their book, Merchants of Doubt, as one of three contrarian physicists—along with Fred Seitz and Bill Nierenberg—who regularly injected themselves into the public debate about contentious scientific issues, positioning themselves as skeptics, their views gaining traction because the media gives them equal time out of a sense of fairness.

Second-hand smoke

According to David Biello and John Pavlus in Scientific American, Singer is best known for his denial of the health risks of passive smoking. He was involved in 1994 as writer and reviewer of a report on the issue by the Alexis de Tocqueville Institution, where he was a senior fellow. The report criticized the Environmental Protection Agency (EPA) for their 1993 study about the cancer risks of passive smoking, calling it "junk science". Singer told CBC's The Fifth Estate in 2006 that he stood by the position that the EPA had "cooked the data" to show that second-hand smoke causes lung cancer. CBC said that tobacco money had paid for Singer's research and for his promotion of it, and that it was organized by APCO. Singer told CBC it made no difference where the money came from. "They don't carry a note on a dollar bill saying 'This comes from the tobacco industry,'" he said. "In any case I was not aware of it, and I didn't ask APCO where they get their money. That's not my business." In December 2010 he wrote in American Thinker that he is nonsmoker who finds second-hand smoke an unpleasant irritant that cannot be healthy; he also wrote that his father, a heavy smoker, died of emphysema when relatively young. According to Singer, he serves on the advisory board of an anti-smoking organization, and has never been paid by Philip Morris or the tobacco lobby.

Global warming

In a 2003 letter to the Financial Times, Singer wrote that "there is no convincing evidence that the global climate is actually warming." In 2006, the CBC's Fifth Estate named Singer as one of a small group of scientists who have created what the documentary called a stand-off that is undermining the political response to global warming. The following year he appeared on the British Channel 4 documentary The Great Global Warming Swindle. Singer argues there is no evidence that the increases in carbon dioxide produced by humans cause global warming, and that if temperatures do rise it will be good for humankind. He told CBC: "It was warmer a thousand years ago than it is today. Vikings settled Greenland. Is that good or bad? I think it's good. They grew wine in England, in northern England. I think that's good. At least some people think so." "We are certainly putting more carbon dioxide in the atmosphere," he told The Daily Telegraph in 2009. "However there is no evidence that this high CO2 is making a detectable difference. It should in principle, however the atmosphere is very complicated and one cannot simply argue that just because CO2 is a greenhouse gas it causes warming." He believes that radical environmentalists are exaggerating the dangers. "The underlying effort here seems to be to use global warming as an excuse to cut down the use of energy," he said. "It's very simple: if you cut back the use of energy, then you cut back economic growth. And believe it or not, there are people in the world who believe we have gone too far in economic growth."

Singers's opinions conflict with the scientific opinion on climate change, where there is overwhelming consensus for anthropogenic global warming, and a decisive link between carbon dioxide concentration and global average temperatures, as well as consensus that such a change to the climate will have dangerous consequences. In 2005 Mother Jones magazine described Singer as a "godfather of global warming denial." However, Singer characterizes himself as a "skeptic" rather than a "denier" of global climate change. In an article in American Thinker, he complains about bad arguments used by the "deniers," saying that "Climate deniers are giving us skeptics a bad name."

SEPP and funding

In 1990 Singer set up the Science & Environmental Policy Project (SEPP) to argue against preventive measures against global warming. After the 1991 United Nations Conference on Environment and Development, the Earth Summit, Singer started writing and speaking out to cast doubt on the science. He predicted disastrous economic damage from any restrictions on fossil fuel use, and argued that the natural world and its weather patterns are complex and ill-understood, and that little is known about the dynamics of heat exchange from the oceans to the atmosphere, or the role of clouds. As the scientific consensus grew, he continued to argue from a skeptical position. He has repeatedly criticized the climate models that predict global warming. In 1994 he compared model results to observed temperatures and found that the predicted temperatures for 1950–1980 deviated from the temperatures that had actually occurred, from which he concluded in his regular column in The Washington Times—with the headline that day "Climate Claims Wither under the Luminous Lights of Science"—that climate models are faulty. In 2007 he collaborated on a study that found tropospheric temperature trends of "Climate of the 20th Century" models differed from satellite observations by twice the model mean uncertainty.

Rachel White Scheuering writes that, when SEPP began, it was affiliated with the Washington Institute for Values in Public Policy, a think tank founded by Unification Church leader Sun Myung Moon. A 1990 article for the Cato Institute identifies Singer as the director of the science and environmental policy project at the Washington Institute for Values in Public Policy, on leave from the University of Virginia. Scheuering writes that Singer had cut ties with the institute, and is funded by foundations and oil companies. She writes that he has been a paid consultant for many years for ARCO, ExxonMobil, Shell, Sun Oil Company, and Unocal, and that SEPP has received grants from ExxonMobil. Singer has said his financial relationships do not influence his research. Scheuering argues that his conclusions concur with the economic interests of the companies that pay him, in that the companies want to see a reduction in environmental regulation.

In August 2007 Newsweek reported that in April 1998 a dozen people from what it called "the denial machine" met at the American Petroleum Institute's Washington headquarters. The meeting included Singer's group, the George C. Marshall Institute, and ExxonMobil. Newsweek said that, according to an eight-page memo that was leaked, the meeting proposed a $5-million campaign to convince the public that the science of global warming was controversial and uncertain. The plan was leaked to the press and never implemented. The week after the story, Newsweek published a contrary view from Robert Samuelson, one of its columnists, who said the story of an industry-funded denial machine was contrived and fundamentally misleading. ABC News reported in March 2008 that Singer said he is not on the payroll of the energy industry, but he acknowledged that SEPP had received one unsolicited charitable donation of $10,000 from ExxonMobil, and that it was one percent of all donations received. Singer said that his connection to Exxon was more like being on their mailing list than holding a paid position. The relationships have discredited Singer's research among members of the scientific community, according to Scheuering. Congresswoman Lynn Rivers questioned Singer's credibility during a congressional hearing in 1995, saying he had not been able to publish anything in a peer-reviewed scientific journal for the previous 15 years, except for one technical comment.

Criticism of the IPCC

In 1995 the Intergovernmental Panel on Climate Change (IPCC) issued a report reflecting the scientific consensus that the balance of evidence suggests there is a discernible human influence on global climate. Singer responded with a letter to Science saying the IPCC report had presented material selectively. He wrote: "the Summary does not even mention the existence of 18 years of weather satellite data that show a slight global cooling trend, contradicting all theoretical models of climate warming." Scheuering writes that Singer acknowledges the surface thermometers from weather stations show warming, but he argues that the satellites provide better data because their measurements cover pole to pole. According to Edward Parson and Andrew Dessler, the satellite data did not show surface temperatures directly, but had to be adjusted using models. When adjustment was made for transient events the data showed a slight warming, and research suggested that the discrepancy between surface and satellite data was largely accounted for by problems such as instrument differences between satellites.

Singer wrote the "Leipzig Declaration on Global Climate Change in the U.S." in 1995, updating it in 1997 to rebut the Kyoto Protocol. The Kyoto Protocol was the result of an international convention held in Kyoto, Japan, during which several industrialized nations agreed to reduce their greenhouse gas emissions. Singer's declaration read: "Energy is essential for economic growth ... We understand the motivation to eliminate what are perceived to be the driving forces behind a potential climate change; but we believe the Kyoto Protocol—to curtail carbon dioxide emissions from only a part of the world community—is dangerously simplistic, quite ineffective, and economically destructive to jobs and standards-of-living."

Scheuering writes that Singer circulated this in the United States and Europe and gathered 100 signatories, though she says some of the signatories' credentials were questioned. At least 20 were television weather reporters, some did not have science degrees, and 14 were listed as professors without specifying a field. According to Scheuering, some of them later said they believed they were signing a document in favour of action against climate change.

Singer set up the Nongovernmental International Panel on Climate Change (NIPCC) after a 2004 United Nations climate conference in Milan. NIPCC organized an international climate workshop in Vienna in April 2007, to provide what they called an independent examination of the evidence for climate change. Singer prepared an NIPCC report called "Nature, Not Human Activity, Rules the Climate," published in March 2008 by The Heartland Institute, a conservative think tank. ABC News said the same month that unnamed climate scientists from NASA, Stanford, and Princeton who spoke to ABC about the report dismissed it as "fabricated nonsense". In a letter of complaint to ABC News, Singer said their piece used "prejudicial language, distorted facts, libelous insinuations, and anonymous smears".

On September 18, 2013, the NIPCC's fourth report, entitled Climate Change Reconsidered II: Physical Science, was published. As with previous NIPCC reports, environmentalists criticized it upon its publication; for example, David Suzuki wrote that it was "full of long-discredited claims, including that carbon dioxide emissions are good because they stimulate life". After the report received favorable coverage from Fox News Channel's Doug McKelway, climate scientists Kevin Trenberth and Michael Oppenheimer criticized this coverage, with Trenberth calling it "irresponsible journalism" and Oppenheimer calling it "flat out wrong".

Climategate

In December 2009, after the Climatic Research Unit email controversy, Singer wrote an opinion piece for Reuters in which he said the scientists had misused peer review, pressured editors to prevent publication of alternative views, and smeared opponents. He said the leaked e-mails showed that the "surface temperature data that IPCC relies on is based on distorted raw data and algorithms that they will not share with the science community." He argued that the incident exposed a flawed process, and that the temperature trends were heading downwards even as greenhouse gases like CO2 were increasing in the atmosphere. He wrote: "This negative correlation contradicts the results of the models that IPCC relies on and indicates that anthropogenic global warming (AGW) is quite small," concluding "and now it turns out that global warming might have been 'man made' after all." A British House of Commons Science and Technology Select Committee later issued a report that exonerated the scientists, and eight committees investigated the allegations, finding no evidence of fraud or scientific misconduct.

Activism

Activism consists of efforts to promote, impede, direct, or intervene in social, political, economic, or environmental reform with the desire to make changes in society. Forms of activism range from mandate building in the community (including writing letters to newspapers), petitioning elected officials, running or contributing to a political campaign, preferential patronage (or boycott) of businesses, and demonstrative forms of activism like rallies, street marches, strikes, sit-ins, or hunger strikes

Activism may be performed on a day-to-day basis in a wide variety of ways, including through the creation of art (artivism), computer hacking (hacktivism), or simply in how one chooses to spend their money (economic activism). For example, the refusal to buy clothes or other merchandise from a company as a protest against the exploitation of workers by that company could be considered an expression of activism. However, the most highly visible and impactful activism often comes in the form of collective action, in which numerous individuals coordinate an act of protest together in order to make a bigger impact. Collective action that is purposeful, organized, and sustained over a period of time becomes known as a social movement.

Historically, activists have used literature, including pamphlets, tracts, and books to disseminate or propagate their messages and attempt to persuade their readers of the justice of their cause. Research has now begun to explore how contemporary activist groups use social media to facilitate civic engagement and collective action combining politics with technology.

Definitions of activism

The Online Etymology Dictionary records the English words "activism" and "activist" as in use in the political sense from the year 1920 or 1915 respectively. The history of the word activism traces back to earlier understandings of collective behavior and social action. As late as 1969 activism was defined as "the policy or practice of doing things with decision and energy", without regard to a political signification, whereas social action was defined as "organized action taken by a group to improve social conditions", without regard to normative status. Following the surge of so-called "new social movements" in the United States in the 1960s, a new understanding of activism emerged as a rational and acceptable democratic option of protest or appeal. However, the history of the existence of revolt through organized or unified protest in recorded history dates back to the slave revolts of the 1st century BC(E) in the Roman Empire, where under the leadership of former gladiator Spartacus 6,000 slaves rebelled and were crucified from Capua to Rome in what became known as the Third Servile War.

In English history, the Peasants' Revolt erupted in response to the imposition of a poll tax, and has been paralleled by other rebellions and revolutions in Hungary, Russia, and more recently, for example, Hong Kong. In 1930 under the leadership of Mahatma Gandhi thousands of protesting Indians participated in the Salt March, as a protest against the oppressive taxes of their government, resulting in the imprisonment of 60,000 people and eventually independence of their nation. In nations throughout Asia, Africa and South America, the prominence of activism organized by social movements and especially under the leadership of civil activists or social revolutionaries has pushed for increasing national self-reliance or, in some parts of the developing world, collectivist communist or socialist organization and affiliation. Activism has had major impacts on Western societies as well, particularly over the past century through social movements such as the Labour movement, the Women's Rights movement, and the civil rights movement.

Types of activism

Activists can function in a number of roles, including judicial, environmental, internet (technological) and design(art). Historically, most activism has focused on creating substantive changes in the policy or practice of a government or industry. Some activists try to persuade people to change their behavior directly (see also direct action), rather than to persuade governments to change laws. For example, the cooperative movement seeks to build new institutions which conform to cooperative principles, and generally does not lobby or protest politically. Other activists try to persuade people or government policy to remain the same, in an effort to counter change

Activism is not an activity always performed by those who profess activism as a profession. The term ″activist″ may apply broadly to anyone who engages in activism, or narrowly limited to those who choose political or social activism as a vocation or characteristic practice.

Judicial and citizen activism

Judicial activism involves the efforts of public officials. Arthur Schlesinger, Jr. - American historian, public intellectual, and social critic - introduced the term "judicial activism" in a January 1946 Fortune magazine article titled "The Supreme Court: 1947". Activists can also be public watchdogs and whistle blowers, attempting to understand all the actions of every form of government that acts in the name of the people and hold it accountable to oversight and transparency. Activism involves an engaged citizenry.

Environmental activism

Environmental activism takes quite a few forms:

Internet activism

The power of Internet activism came into a global lens with the Arab Spring protests starting in late 2010. People living in the Middle East and North African countries that were experiencing revolutions used social networking to communicate information about protests, including videos recorded on smart phones, which put the issues in front of an international audience. This was the one of the first occasions in which social networking technology was used by citizen-activists to circumvent state-controlled media and communicate directly with the rest of the world. These types of practices of Internet activism were later picked up and used by other activists in subsequent mass mobilizations, such as the 15-M Movement in Spain in 2011, Occupy Gezi in Turkey in 2013, and more.

Internet activism may also refer to activism which focuses on protecting or changing the Internet itself, also known as digital rights. The Digital Rights movement consists of activists and organizations, such as the Electronic Frontier Foundation, who work to protect the rights of people in relation to new technologies, particularly concerning the Internet and other information and communications technologies.

Activism in literature

Activism in literature (not to be confused with literary activism) includes the expression of intended or advocated reforms, realized or unachieved, through published, written or verbally promoted or communicated forms.

Economic activism

Economic activism involves using the economic power of government, consumers, and businesses for social and economic policy change. Both conservative and liberal groups use economic activism to as a form of pressure to influence companies and organizations to oppose or support particular political, religious, or social values and behaviors. This is typically done either through preferential patronage to reinforce "good" behavior and support companies one would like to succeed, or through boycott or divestment to penalize "bad" behavior and pressure companies to change or go out of business. 

Consumer activism consists of activism carried out on behalf of consumers for consumer protection or by consumers themselves. For instance, activists in the free produce movement of the late 1700s protested against slavery by boycotting goods produced with slave labor. Today, vegetarianism, veganism, and freeganism are all forms of consumer activism which boycott certain types of products. Other examples of consumer activism include simple living, a minimalist lifestyle intended to reduce materialism and conspicuous consumption, and tax resistance, a form of direct action and civil disobedience in opposition to the government that is imposing the tax, to government policy, or as opposition to taxation in itself

Shareholder activism involves shareholders using an equity stake in a corporation to put pressure on its management. The goals of activist shareholders range from financial (increase of shareholder value through changes in corporate policy, financing structure, cost cutting, etc.) to non-financial (disinvestment from particular countries, adoption of environmentally friendly policies, etc.).

Visual Activism

Design Activism locates design at the centre of promoting social change, raising awareness on social/political issues, or questioning problems associated with mass production and consumerism. Design Activism is not limited to one type of design.

Art Activism or Artivism utilizes the medium of visual art as a method of social or political commentary.

Methods

The longest running peace vigil in U.S. history, started by activist Thomas in 1981.
 
Activists employ many different methods, or tactics, in pursuit of their goals. Decisions over what tactics to use or not may be planned carefully in advance, result from negotiations with law enforcement such as when and where to hold a rally, or be made in the heat of the moment. The tactics chosen are significant because they can determine how activists are perceived and what they are capable of accomplishing. For example, nonviolent tactics generally tend to garner more public sympathy than violent ones and are more than twice as effective in achieving stated goals.

Charles Tilly developed the concept of a “repertoire of contention,” which describes the full range of tactics available to activists at a given time and place. This repertoire consists of all of the tactics which have been proven to be successful by activists in the past, such as boycotts, petitions, marches, and sit-ins, and can be drawn upon by any new activists and social movements. Activists may also innovate new tactics of protest. These may be entirely novel, such as Douglas Schuler's idea of an "activist road trip", or may occur in response to police oppression or countermovement resistance. New tactics then spread to others through a social process known as diffusion, and if successful, may become new additions to the activist repertoire.

Many contemporary activists now utilize new tactics through the Internet and other information and communication technologies (ICTs), also known as Internet activism or cyber-activism. Some scholars argue that many of these new tactics are digitally analogous to the traditional offline tools of contention. Other digital tactics may be entire new and unique, such as certain types of hacktivism. Together they form a new "digital repertoire of contention" alongside the existing offline one. The rising use of digital tools and platforms by activists has also increasingly led to the creation of decentralized networks of activists that are self-organized and leaderless, or what is known as franchise activism

Common methods used for activism include:

Activism industry

Some groups and organizations participate in activism to such an extent that it can be considered as an industry. In these cases, activism is often done full-time, as part of an organization's core business. Many organizations in the activism industry are either non-profit organizations or non-governmental organizations with specific aims and objectives in mind. Most activist organizations do not manufacture goods, but rather mobilized personnel to recruit funds and gain media coverage. 

The term activism industry has often been used to refer to outsourced fundraising operations. However, activist organizations engage in other activities as well. Lobbying, or the influencing of decisions made by government, is another activist tactic. Many groups, including law firms, have designated staff assigned specifically for lobbying purposes. In the United States, lobbying is regulated by the federal government.

Many government systems encourage public support of non-profit organizations by granting various forms of tax relief for donations to charitable organizations. Governments may attempt to deny these benefits to activists by restricting the political activity of tax-exempt organizations.

The Eemian (also called the last interglacial, Sangamonian Stage, Ipswichian, Mikulin, Kaydaky, penultimate, Valdivia or Riss-Würm) was the interglacial period which began about 130,000 years ago at the end of the Penultimate Glacial Period and ended about 115,000 years ago at the beginning of the Last Glacial Period. It corresponds to Marine Isotope Stage 5e. Although sometimes referred to as the "last interglacial" (in the "most recent previous" sense of "last"), it was the second-to-latest interglacial period of the current Ice Age, the most recent being the Holocene which extends to the present day (having followed the last glacial period). The prevailing Eemian climate was, on average, around 1 to 2 degrees Celsius (1.8 to 3.6 Fahrenheit) warmer than that of the Holocene. During the Eemian, the proportion of CO
2
in the atmosphere was about 280 parts per million.

The Eemian is known as the Ipswichian in the UK, the Mikulin interglacial in Russia, the Valdivia interglacial in Chile and the Riss-Würm interglacial in the Alps. Depending on how a specific publication defines the Sangamonian Stage of North America, the Eemian is equivalent to either all or part of it. 

The period falls into the Middle Paleolithic and is of some interest for the evolution of anatomically modern humans, who were present in West Asia (Skhul and Qafzeh hominins) as well as in Southern Africa by this time, representing the earliest split of modern human populations that persists to the present time (associated with mitochondrial haplogroup L0).

Global temperatures

The Eemian climate is believed to have been a little warmer than the current Holocene. Changes in the Earth's orbital parameters from today (greater obliquity and eccentricity, and perihelion), known as Milankovitch cycles, probably led to greater seasonal temperature variations in the Northern Hemisphere. Although global annual mean temperatures were probably several degrees warmer than today, during summer months, temperatures in the Arctic region were about 2-4 °C higher than today. The warmest peak of the Eemian was around 125,000 years ago, when forests reached as far north as North Cape, Norway (which is now tundra) well above the Arctic Circle at 71°10′21″N 25°47′40″E. Hardwood trees such as hazel and oak grew as far north as Oulu, Finland.

At the peak of the Eemian, the Northern Hemisphere winters were generally warmer and wetter than now, though some areas were actually slightly cooler than today. The hippopotamus was distributed as far north as the rivers Rhine and Thames. Trees grew as far north as southern Baffin Island in the Canadian Arctic Archipelago: currently, the northern limit is further south at Kuujjuaq in northern Quebec. Coastal Alaska was warm enough during the summer due to reduced sea ice in the Arctic Ocean to allow Saint Lawrence Island (now tundra) to have boreal forest, although inadequate precipitation caused a reduction in the forest cover in interior Alaska and Yukon Territory despite warmer conditions. The prairie-forest boundary in the Great Plains of the United States lay further west near Lubbock, Texas, whereas the current boundary is near Dallas. The period closed as temperatures steadily fell to conditions cooler and drier than the present, with a 468-year-long aridity pulse in central Europe at about 116,000 BC, and by 112,000 BC, a glacial period had returned. 

Kaspar et al. (GRL, 2005) performed a comparison of a coupled general circulation model (GCM) with reconstructed Eemian temperatures for Europe. Central Europe (north of the Alps) was found to be 1–2 °C (1.8–3.6 °F) warmer than present; south of the Alps, conditions were 1–2 °C cooler than today. The model (generated using observed greenhouse gas concentrations and Eemian orbital parameters) generally reproduces these observations, leading them to conclude that these factors are enough to explain the Eemian temperatures.

A 2018 study based on soil samples from Sokli in northern Finland identified abrupt cold spells ca. 120,000 years ago caused by shifts in the North Atlantic Current, lasting hundreds of years and causing temperature drops of a few degrees and vegetation changes in these regions.

Sea level

Sea level at peak was probably 6 to 9 metres (20 to 30 feet) higher than today, with Greenland contributing 0.6 to 3.5 m (2.0 to 11.5 ft), thermal expansion and mountain glaciers contributing up to 1 m (3.3 ft), and an uncertain contribution from Antarctica. Recent research on marine sediment cores offshore of the West Antarctic Ice Sheet suggest that the sheet melted during the Eemian, and that ocean waters rose as fast as 2.5 meters per century. Global mean sea surface temperatures are thought to have been higher than in the Holocene, but not by enough to explain the rise in sea level through thermal expansion alone, and so melting of polar ice caps must also have occurred. Because of the sea level drop since the Eemian, exposed fossil coral reefs are common in the tropics, especially in the Caribbean and along the Red Sea coastlines. These reefs often contain internal erosion surfaces showing significant sea level instability during the Eemian. 

A 2007 study found evidence that the Greenland ice core site Dye 3 was glaciated during the Eemian, which implies that Greenland could have contributed at most 2 m (6.6 ft) to sea level rise. Scandinavia was an island due to the inundation of vast areas of northern Europe and the West Siberian Plain.

Definition of the Eemian

Bittium reticulatum Picture from Harting (1886) assigned by him as 'Index fossil' for the Eemian.
 
The Eemian Stage was first recognized from boreholes in the area of the city of Amersfoort, Netherlands, by Harting (1875). He named the beds "Système Eémien", after the river Eem on which Amersfoort is located. Harting noticed the marine molluscan assemblages to be very different from the modern fauna of the North Sea. Many species from the Eemian layers nowadays show a much more southern distribution, ranging from South of the Strait of Dover to Portugal (Lusitanian faunal province) and even into the Mediterranean (Mediterranean faunal province). More information on the molluscan assemblages is given by Lorié (1887), and Spaink (1958). Since their discovery, Eemian beds in the Netherlands have mainly been recognized by their marine molluscan content combined with their stratigraphical position and other palaeontology. The marine beds there are often underlain by tills that are considered to date from the Saalian, and overlain by local fresh water or wind-blown deposits from the Weichselian. In contrast to e.g. the deposits in Denmark, the Eemian deposits in the type area have never been found overlain by tills, nor in ice-pushed positions.

Van Voorthuysen (1958) described the foraminifera from the type site, whereas Zagwijn (1961) published the palynology, providing a subdivision of this stage into pollen stages. At the end of the 20th century, the type site was re-investigated using old and new data in a multi-disciplinary approach (Cleveringa et al., 2000). At the same time a parastratotype was selected in the Amsterdam glacial basin in the Amsterdam-Terminal borehole and was the subject of a multidisciplinary investigation (Van Leeuwen, et al., 2000). These authors also published a U/Th age for late Eemian deposits from this borehole of 118,200 ± 6,300 years ago. A historical review of Dutch Eemian research is provided by Bosch, Cleveringa and Meijer, 2000.
