North American Birds Shift Northward Due to Global Warming

A new study in Conservation Biology analyzed the breeding ranges of North American birds over a 26-year period. The results show that the ranges have shifted northward; coinciding with a period of increasing global temperatures. These results were similar to those found in studies conducted in Great Britain, showing the worldwide extent of these distributional changes..........

Study Finds Earth Reaching Warmest Levels Since Thousands of Years Ago

The study appears in the current issue of the Proceedings of the National Academy of Sciences, authored by James Hansen of NASA's Goddard Institute for Space Studies, N.Y. and colleagues from Columbia University, Sigma Space Partners, Inc., and the University of California at Santa Barbara (UCSB). The study concludes that, because of a rapid warming trend over the past 30 years, the Earth is now reaching and passing through the warmest levels in the current interglacial period, which has lasted nearly 12,000 years. This warming is forcing a migration of plant and animal species toward the poles..........

Increased Methane Release from Oceans on the Horizon?

The last two times the Earth warmed considerably and put glaciers on the run, huge plumes of the potent greenhouse gas methane bubbled out of the ocean off the California coast.

An international team of researchers say they think they know why. If they're right, manmade greenhouse warming could unleash fresh plumes of seabed methane along the North American and European coasts that could make the planet warmer still and speed the acidification of the oceans..........
