It's March, but a big snow has fallen in the U.S. Northeast for perhaps the first time this winter. What's going on in traditional New England "snow towns" like Boston, Burlington and Brattleboro--and atop New Hampshire's famed Mount Washington, which is often snow-covered through July?

An analysis of the remains of ancient midges opens a new window on the past with a detailed view of the surprising regional variability that accompanied climate warming during the early Holocene epoch, 10,000 to 5,500 years ago.

The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science.

New NSF grants seek to improve predictions of climate change and how it will affect Earth's future.

Is it possible to make valid climate predictions that go beyond weeks, months, even a year?
