The first discoveries
Joseph Black discovered carbon dioxide and realized first climate changes due to global warming. -
More Discoveries
scientist Jean-Baptiste Fourier suggested an atmospheric effect was present that kept the Earth much warmer than it would be normally. He used the idea of a greenhouse to describe this warming effect. -
John Tyndall
Irish physicist John Tyndall carried out research on radiant heat and the absorption of radiation by gases and vapours including CO2 and H2O. He showed that carbon dioxide and water vapour are heat-trapping gases. -
discoveries
Svante Arrhenius predicted carbon dioxide release from the coal burning would trap heat in the atmosphere and cause global warming. -
Warning signs
a computer simulation predicted that average global temperatures will most likely increase by more than four degrees Fahrenheit, depending on levels of carbon dioxide. -
12 yrs. later...
Many years post the world held its first climate conference. The conference called on governments to look into the issue at hand and prevent it in any way possible. -
close links
an ice core from Antarctica revealed an extremely close link between carbon dioxide levels and temperature going back more than 100,000 years. -
The Governments assisitance is now in action
The World Meteorological Organization and the United Nations Environment Program created the Intergovernmental Panel on Climate Change. Its role was to assess what we know about the climate system, the impacts of climate change and possible ways forward more research and possible ways to help the crisis. -
ipcc reports bad news
Third IPCC report states baldly that global warming, unprecedented since end of last ice age, is "very likely," with possible severe surprises. Effective end of debate among all but a few scientists. -
oceans getting warmer
An apparent pause or "hiatus" in global warming of the atmosphere since 1998 is discussed and explained; the oceans have continued to get warmer. -
