Some people believe the Intergovernmental Panel on Climate Change (IPCC) is a small, unified body composed of the best scientists who make proclamations on lots of things. That isn't really true. The…

The climate just got a little more complex.  Researchers have found that sunlit snow is a major source of atmospheric bromine in the Arctic and that the surface snowpack above Arctic sea ice…

 Average sea level changes have averaged about 3 millimeters annually in recent years, leading the 2007 Intergovernmental Panel on Climate Change report to estimate that sea levels could…

Rising temperatures will lead to a "greening" of the Arctic by mid-century, according to a new numerical model.  The greening not only will have effects on plant life, the researchers noted, but…

Sea-level rise over the coming century could affect some regions far more than others, according to a numerical model which projects that parts of the Pacific will see the highest rates of rise while…

Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and can release climate-warming carbon dioxide gas into the atmosphere faster than previously thought if exposed to…

There are projections that coral reefs will decline due to global warming but evolution disagrees. A number of coral species survive at seawater temperatures far higher than estimates for the tropics…

A new study details changes in Earth's climate from more than 100,000 years ago and indicates that the last interglacial, the term for the periods between "ice ages", was warmer than previously…

Arctic sea ice has not only declined over the past decade but has also become distinctly thinner and younger - mainly thin, first-year ice floes which are extensively covered with melt ponds in the…

Reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years show that greenhouse gas concentrations similar to the present (nearly 400 parts per million) were…
