1800-1870

Level of carbon dioxide gas (CO2) in the atmosphere, as later measured in ancient ice, is about 290 parts per million (ppm).

First Industrial Revolution. Coal, railroads, and land clearing speed up greenhouse gas emission, while better agriculture and sanitation speed up population growth.

1827

French polymath Jean-Baptiste Fourier suggests the existence of an atmospheric effect keeping the Earth warmer than it would be otherwise. He also uses the analogy of a greenhouse.

1859

Irish atmospheric scientist, John Tyndall, discovers that some gasses block infrared radiation. He publishes a paper in 1863 describing how water vapor can be a greenhouse gas, and suggests that changes in the concentration of the gases could bring about climate change.

1896

Swedish scientist Svante Arrhenius publishes the first calculation of global warming from human emissions of CO2.

1897

1938

British scientist, G.S. Callendar argues that CO2 greenhouse global warming is underway, reviving interest in the question.

1939-1945

World War II. Grand strategy is largely driven by a struggle to control oil fields.

1945

U.S. Office of Naval Research begins generous funding of many fields of science, some of which happen to be useful for understanding climate change.

1956

American geophysicist, Maurice Ewing (along with William Donn), offer a feedback model for a quick ice age onset. American theoretical meteorologist, Norman Phillips, produces a somewhat realistic computer model of the global atmosphere. American physicist, Gilbert Plass, calculates that adding CO2 to the atmosphere will have a significant effect on the radiation balance.

1957

American oceanographer, Roger Revelle, warns that people are conducting a large-scale geophysical experiment on the planet by releasing greenhouse gases, and that CO2 produced by humans will not be readily absorbed by the oceans. His colleague, David Keeling, sets up the first continuous monitoring of CO2 levels in the atmosphere. Immediately, Keeling finds a regular year-on-year rise of CO2 levels.

The launch of Soviet Sputnik satellite heightens Cold War concerns, causing support for the 1957-1958 International Geophysical Year, bringing new funding and coordination to climate studies.

1958

Telescope studies show a greenhouse effect raises temperature of the atmosphere of Venus, far above the boiling point of water.

1960

Downturn of global temperatures since the early 1940s is reported. David Keeling accurately measures CO2 in the Earths atmosphere and detects an annual rise.

1963

Calculations suggest that feedback with water vapor could make the climate acutely sensitive to changes in CO2 levels.

1965

At a landmark conference on Causes of Climate Change, held in Boulder, Colorado, American meteorologist, Edward Lorenz (the father of chaos theory) and others point out the chaotic nature of climate systems and the possibility of sudden shifts.

1966

Italian-American scientist, Cesare Emilianis analysis of deep-sea cores shows the timing of the ice ages was set by small orbital shifts, suggesting that the climate system is sensitive to small changes.

1967

An International Global Atmospheric Research Program is established, mainly to gather data for better short-range weather predictions, but also including climate predictions.

1968

Studies suggest a possibility of a collapse of Antarctic ice sheets, which would raise sea levels catastrophically.

1969

Astronauts walk on the Moon, and people perceive the Earth as a fragile whole. The Nimbus III satellite begins to provide comprehensive global atmospheric temperature measurements.

1970

A series of studies by the US Department of Energy increases concerns about future global warming. The Environmental movement attains strong influence, and the first Earth Day is established. Aerosols from human activity are shown to be increasing swiftly, which American meteorologist, Reid Bryson, proposes counteract global warming and may bring about serious cooling. The National Oceanic and Atmospheric Administration (NOAA) the worlds leader of climate research, is created.

1972

Ice cores and other evidence show big climate shifts in the past between relatively stable modes in the space of a thousand years or so, especially around 11,000 years ago.

1974

Serious droughts and other unusual weather since 1972 increase scientific and public concern about climate change, with cooling from aerosols suspected to be as likely as warming. Journalists began to talk of a new ice age.

1975

Concern about environmental effects of airplanes leads to investigations of trace gases in the stratosphere and discovery of danger to the ozone layer.

1976

Studies show that CFCs, methane, and ozone can make a serious contribution to the greenhouse effect. Deep-sea cores show a dominating influence from 100,000-year Milankovitch orbital changes, emphasizing the role of feedbacks. Deforestation and other ecosystem changes are recognized as major factors in the future of the climate.

1977

Scientific opinion tends to converge on global warming, not cooling, as the chief climate risk in the next century.

1979

The first World Climate Conference adopts climate change as major issue and calls on governments to foresee and prevent potential man-made changes in climate. A strengthened environmental movement encourages renewable energy sources, and inhibits nuclear energy growth. A US National Academy of Sciences report find it highly credible that doubling CO2 will bring 1.5 to 4.5 degrees centigrade global warming.

1981

The election of Ronald Reagan brings a backlash against the environmental movement. Political conservatism is linked to skepticism about global warming.

1983

Reports from the US National Academy of Sciences and Environmental Protection Agency spark conflict, as greenhouse warming becomes prominent in mainstream politics.

1985

First major international conference on the greenhouse effect at Villach, Austria warns that greenhouse gases will in the first half of the next century, cause a rise of global mean temperature which is greater than any in mans history. This could cause sea levels to rise by up to a meter, researchers say. Conference also reports that gases other than CO2, such as methane, ozone, CFCs and nitrous oxide, will also contribute to warming.

1987

Warmest year on record thus far. The 1980s turn out to be the warmest decade, with seven of the eight warmest years recorded up to 1990. Even the coldest years in the 1980s were warmer than the warmest years of the 1880s. The Montreal Protocol of the Vienna Convention imposes international restrictions on emission of ozone-destroying gases.

1988

Global warming attracts worldwide headlines after Dr. James Hansen of NASA Goddard Institute for Space Studies lab tells a Congressional hearing global warming is at hand. And blames a major US drought which fueled massive wildfires in Yellowstone Park on its influence. Meeting of climate scientists in Toronto subsequently calls for 20 per cent cuts in global CO2 emissions by the year 2005. UN sets up the Intergovernmental Panel on Climate Change (IPCC) to analyze and report on scientific findings.

US Congresswoman, Claudine Schneider (R-RI), authors the first significant piece of legislation aimed at reducing greenhouse gas emissions, the Global Warming Prevention Act.

1990

The first IPCC report finds that the plant has warmed by 0.5 degrees C in the past century. IPCC warns that only strong measures to halt rising greenhouse gas emissions will prevent serious global warming. Provides scientific clout for UN negotiations for a climate convention. Negotiations begin after the UN General Assembly in December. Industry lobbyists and some scientists dispute the tentative conclusions.

1991

Mt. Pinatubo explodes in the Philippines, throwing debris into the stratosphere that shields the Earth from solar energy, which help interrupt the warming trend. Average temperatures drop for two years before rising again. Scientists point out that this event shows how sensitive global temperatures are to disruption. Global warming skeptics emphasize studies indicating that a significant part of 20th-century temperature changes were due to solar influences.

1992

The Framework Convention on Climate Change, signed by 154 nations in Rio, agrees to prevent dangerous warming from greenhouse gases and sets initial target of reducing emissions from industrialized countries to 1990 levels by the year 2000. President George Bush signs on behalf of the United States.

More than 4,000 scientists from 106 countries, including 72 Nobel Prize winners, signed the Heidelberg Appeal, calling for a rational scientific approach to environmental problems.

1995

The hottest year yet. The Berlin Mandate is agreed by signatories at the first full meeting of the Climate Change Convention in Berlin. Industrialized nations agree on the need to negotiate real cuts in their emissions, to be concluded by the end of 1997. The IPCC agrees that current warming is unlikely to be entirely natural in origin and that the balance of evidence suggests a discernible human influence on global climate.

1996

At the second meeting of the Climate Change Convention, the US and President Bill Clintons administration agree for the first time to legally binding emissions targets and sides with the IPCC against influential skeptical scientists. After a four year pause, global emissions of CO2 continue their steep climb, and scientists warn that most industrialized countries will not meet Rio agreement to stabilize emissions at 1990 levels by the year 2000.

1997

International conference produces Kyoto Protocol, which suggests legally binding emissions cuts for industrialized nations, averaging 5.5 per cent, to be met by 2010. The US government says it will not ratify the agreement unless it sees evidence of meaningful participation in reducing emissions from developing countries.

1998

Follow-up negotiations in Buenos Aires fail to resolve disputes over the Kyoto rule book, but agree on a deadline for resolution by the end of 2000. 1998 is the hottest year in the hottest decade of the hottest century of the millennium.

2001

Newly elected US President, George W. Bush, renounces the Kyoto Protocol because he questions the science and he believes it will damage the US economy.

2002

The United States sends its U.S. Climate Action Report 2002, to the UN. The report strongly concludes that no matter what is done to cut emissions in the future, nothing can be done about the environmental consequences of several decades worth of carbon dioxide and other heat-trapping gases already in the atmosphere. It further states that some of the goods and services lost through the disappearance or fragmentation of natural ecosystems are likely to be costly or impossible to replace.

2003

Variety of studies increase concern that collapse of ice sheets can raise sea levels faster than most had believed. A deadly summer heat wave in Europe accelerates divergence between European and US public opinion.

2004

In controversy over temperature data covering past millennium, most conclude climate variations were substantial, but not comparable to post-1980 warming.

2005

Kyoto treaty goes into effect, signed by major industrial nations except for the US, Japan, and Western Europe. Hurricane Katrina and other major tropical storms spur debate over impact of global warming on storm intensity.

2006

A group describing itself as "sixty scientists" signed an Open Letter to Canadian Prime Minister Stephen Harper to ask that he revisit the science of global warming and "Open Kyoto to debate". As with the earlier statements, critics pointed out that many of the signatories were non-scientists or lacked relevant scientific backgrounds.

2007

The first major global assessment of climate change science in six years has concluded that changes in the atmosphere, the oceans and glaciers and ice caps show unequivocally that the world is warming. The Intergovernmental Panel on Climate Change (IPCC) concludes that major advances in climate modeling and the collection and analysis of data now give scientists very high confidence (at least a 9 out of 10 chance of being correct) in their understanding of how human activities are causing the world to warm.

2008

Sept- This year, the sea ice was measured at 1.74 million square miles, the second-smallest size since NASA started reporting satellite data in 1979. That compares to last summer's record low of 1.59 million square miles.(San Francisco Chronicle)

2009

August- On July 15th, Greenpeace released a statement that the arctic ice caps would melt by 2030, a claim that Gerd Leipold, it's executive director, now admits was falsified. The group's leader made no apologies, saying Greenpeace is "a pressure group" that has to "emotionalize issues, and we're not ashamed" of it.

2009

“Climategate” -  In late 2009, computer hackers obtained more than 1,000 emails sent and received from researchers at the Climate Research Unit at the University of East Anglia in England. The e-mails reportedly exposed the fact that data that did not support global warming claims had been destroyed or hidden. Supporters of global warming continue to hold that evidence supports global warming—and that humans are largely responsible. (www.foxnews.com and www.factcheck.org)

A nationwide cap-and-trade system for carbon pollution was passed by the House. 

2010

Professor Mojib Latif, a leading climate modeler, reported in January 2010 that the cooler temps in America are kicking off a thirty-year cool-down, or a “mini ice age” that will be just a brief interruption in the larger cycle of global warming. (www.foxnews.com) 

The nationwide cap-and-trade system for carbon pollution, passed by the House in 2009 died in the Senate this year. 

2011

United Nations Framework Convention on Climate Change was held in Durban, South Africa, with representatives from about 200 nations attending. The meetings resulted in the promise to work toward a new global treaty in coming years and to establish a new climate fund (New York Times.com)


The UN’s weather agency reported that 2011 was tied for tenth place in the list of warmest years on record since 1850. (Huffington Post)

The World Meteorological Organization reported that Arctic sea ice, an indicator of global warming, had decreased to a record low volume. (Huffington Post)

Dr. Ivar Giaever, a former professor 1973 winner of the Nobel Prize in physics, resigned from the American Physical Society, because of disagreement with the APS’ official statement that "global warming is occurring." (Fox news)

2012

CO2 Is Not Driving Global Warming (August 30, 2012) - An important new paper published today in Global and Planetary Change finds that changes in CO2 follow rather than lead global air surface temperature and that “CO2 released from use of fossil fuels have little influence on the observed changes in the amount of atmospheric CO2.” The paper finds the “overall global temperature change sequence of events appears to be from 1) the ocean surface to 2) the land surface to 3) the lower troposphere,” in other words, the opposite of claims by global warming alarmists that CO2 in the atmosphere drives land and ocean temperatures.

CO2 Levels Lagging Effect of Ocean Warming - As in the ice cores, CO2 levels are found to be a lagging effect of ocean warming, not significantly related to man-made emissions, and not the driver of warming. Prior research has shown infrared radiation from greenhouse gases is incapable of warming the oceans, only shortwave radiation from the sun is capable of penetrating and heating the oceans and thereby driving global surface temperatures.

Leaked Emails Expose US - UK Science Fraud on Global Warming - Mission Galactic Freedom reports leaked emails between the University of East Anglia and their U.S. counterparts show fraud by the G20 propaganda machine.The leak of those emails blew away the G20 scam and proved that this was simply a measure to create stealth taxes on the ordinary people of this world and for the poorer countries to be bullied in taking western technology and  huge debts via the World Bank and the IMF. Most of that information has now been removed and no longer available on the original University of East Anglia Web page.

U.N. Global Warming Treaty Is Derailed - More than a decade of correspondence between leading British and U.S. scientists was included in about 1,000 e-mails and 3,000 documents posted on Web sites following the massive security breach..Some climate change sceptics and bloggers claim the information shows scientists had overstated the case for global warming and allege the documents contain proof that some researchers have attempted to manipulate data. The leaked data came weeks before the U.N. climate conference in Copenhagen, when 192 nations were trying to reach a binding treaty to reduce emissions of carbon dioxide and other heat-trapping greenhouse gases worldwide. Many officials – including U.N. Secretary-General Ban Ki-moon – regard the prospects of a pact being sealed at the meeting as bleak.

Overturning the Global Warming Hoax -  (January 24, 2012). James Delingpole of The Telegraph reports that the British Parliament heard devastating testimony overturning the global warming hoax from MIT’s Richard Lindzen who is the Alfred P. Sloan Professor of Meteorology, Department of Earth, Atmospheric and Planetary Sciences.  Professor Lindzen sounded the alarm early over the systematic subversion of Climate Sciences in North America and Europe by a cabal centered around Al Gore and the UN’s Maurice Strong.

Reconsider the Climate Change Act - The Telegraph has published Professor Lindzen’s presentation on the global warming hoax as the House of Commons undertakes to enact  “Reconsider the Climate Change Act” – Professor Lindzen stated the provisions within the global warming hoax have decimated the British economy and that U.S. lawmakers somehow are unable to organize an effective political debate thus far over global warming hysteria that is affecting everything from Solyndra to the Keystone Pipeline, even though he is available to testify before Congress.  This renewed debate in Parliament represents a significant shift in the balance of power against the eco-fanatics.

2013

Global Warming Update - Temperatures have been below normal in 75% of the U.S. tornadoes have been below normal. Forest fires have been at a record low. The permanent corn belt drought is over. Arctic ice is very close to normal. Antarctic ice is above normal. Arctic temperatures are at  a record low for this time of year. No global warming for over 17 years. Longest period since the Civil War without a major hurricane landfall in the U.S. Despite the fact that there is zero evidence supporting their position, our apocalyptic friends continue to ramp up the lies – with full support from the White House.

Global Warming  the Latest Official Update  -  The Lysenko list of our leftwing is more apparent than ever with the release of the second part of IPCC’s latest report (AR5) on global warming.  It turns out that they’re quietly walking back the hysteria generated over the last years,  the warming is 1) not anywhere near as large as previously predicted, 2) is coming later than predicted, and 3) is not going to cause all the predicted damage to life on earth. In fact, if anything, the warming will create new millions of square miles of arable land suitable for growing more food for the planet’s hungry. (March 29, 2014)
