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.
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.
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.
Swedish scientist Svante Arrhenius publishes the first
calculation of global warming from human emissions of CO2.
American, P.C. Chamberlain produces a model for global
carbon exchange including feedbacks.
Second Industrial Revolution. Fertilizers and other
chemicals, electricity, and public health further accelerate growth.
World War I; governments learn to mobilize and control
Opening of Texas and Persian Gulf oil fields inaugurates era
of cheap energy.
Global warming trend since late 19th century is
reported. Serbian astrophysicist, Milutin Milankovitch proposes orbital changes
as the cause of ice ages.
British scientist, G.S. Callendar argues that CO2 greenhouse
global warming is underway, reviving interest in the question.
World War II. Grand strategy is largely driven by a struggle
to control oil fields.
U.S. Office of Naval Research begins generous funding of
many fields of science, some of which happen to be useful for understanding
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
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.
Telescope studies show a greenhouse effect raises
temperature of the atmosphere of Venus, far above the boiling point of water.
Downturn of global temperatures since the early 1940s is
reported. David Keeling accurately measures CO2 in the Earths atmosphere and
detects an annual rise.
Calculations suggest that feedback with water vapor could
make the climate acutely sensitive to changes in CO2 levels.
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.
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.
An International Global Atmospheric Research Program is
established, mainly to gather data for better short-range weather predictions,
but also including climate predictions.
Studies suggest a possibility of a collapse of Antarctic ice
sheets, which would raise sea levels catastrophically.
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.
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.
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.
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.
Concern about environmental effects of airplanes leads to
investigations of trace gases in the stratosphere and discovery of danger to
the ozone layer.
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.
Scientific opinion tends to converge on global warming, not
cooling, as the chief climate risk in the next century.
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.
The election of Ronald Reagan brings a backlash against the
environmental movement. Political conservatism is linked to skepticism about
Reports from the US National Academy of Sciences and
Environmental Protection Agency spark conflict, as greenhouse warming becomes
prominent in mainstream politics.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
In controversy over temperature data covering past
millennium, most conclude climate variations were substantial, but not
comparable to post-1980 warming.
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
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
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.
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)
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.
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

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.
Emails Expose US - UK Science Fraud on Global Warming -
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.
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
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
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

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)
Climategate: We are STILL being tricked
with flawed data on global warming.
As reported in the London Telegraph earlier this
year, "The Earth's recent
temperatures rank in the lowest 3 per cent of all those recorded since the
end of the last ice age."
Something very odd has been going on with the
temperature data relied on by the world's scientists, writes Christopher
Booker: The fiddling with temperature data is the biggest science scandal
ever. New data also shows that the "vanishing" of polar ice is not the
result of runaway global warming.
