Paris, 2 Feb 2007 - Late last night, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) adopted the Summary for Policymakers of the first volume of "Climate Change 2007", also known as the Fourth Assessment Report (AR4). "Climate Change 2007: The Physical Science Basis" was produced by some 600 authors from 40 countries. Over 620 expert reviewers and a large number of government reviewers also participated.

GlobalWarming Awareness2007 Report


Paris, 2 Feb 2007 — The world's climate scientists reported unequivocally that the Earth's climate system is increasingly heating up and that it likely has not been this warm for at least 1300 years. The fourth report of the UN's Intergovernmental Panel on Climate Change says that evidence for this includes more than increases in global average air and ocean temperatures.

The forecast range of possible temperatures by the end of the century reaches higher in this report than did the previous one in 2001 — 11.5 degrees F — but the more probable range is between 3.2 and 7 degrees F. The rate of rise depends on if and how fast emissions are reduced and on possible adverse feedbacks in the climate system.

All probable temperatures are far beyond the increase in the 20th C and will take modern civilization into uncharted territory. Temperatures are sure to rise faster in the next decades, the IPCC said, as they did on average in the last half of the 20th century.

Even now, the scientists reported, the last time the Arctic was significantly warmer was about 125,000 years ago, before the last ice age. At that time, sea level rose 4 to 6 meters as polar ice melted. For this coming century the IPCC is forecasting sea level to rise from 7 inches to about half a meter, depending on emissions and warming. The scientists expressed uncertainty about rapid melting of the Greenland ice cap, citing a lack of enough research so far; this is sure to be one of the more controversial parts of the report since some glaciologists think Greenland will add considerably to sea level.

If CO2 emissions can be reduced far enough, the report estimated, the atmosphere could be stabilized at a much lower level of greenhouse effect than is forecast now. Still, the effects of global warming will be with us for many centuries, the IPCC said, because of the inertia of the atmosphere and oceans and the 100 + year persistence of greenhouse gases.
