IPCC Report on Climate Change. The assessment reported on observed changes in temperature, rainfall, storms, ice cover, and other climate features. [IPCC Webcast]
Arctic, Antarctic Melting May Raise Sea Levels. Scientists blend computer modeling with paleoclimate records to show that Arctic summers by 2100 may be as warm as they were nearly 130,000 years ago, when sea levels eventually rose up to 20 feet (6 meters) higher than today.
Most of Arctic's Near-Surface Permafrost May Thaw by 2100. Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia.
Warmer Seas, Wetter Air Make Harder Rains as Greenhouse Gases Build. Storms will dump heavier rain and snow around the world as Earth's climate warms over the coming century, according to several leading computer models.
Climate Model Links Higher Temperatures to Prehistoric Extiction. Scientists have created a computer simulation showing Earth's climate in unprecedented detail that gives support to a theory that an abrupt and dramatic rise in atmospheric levels of carbon dioxide triggered the massive die-off 251 million years ago.
