How stable are the glaciers of East Antarctica? Tim Creyts, a polar expert at Columbia University's Lamont-Doherty Earth Observatory explains how they may be threatened by climate change.

“Cloud cover is plummeting in southern coastal California,” said Park Williams, a bioclimatologist at Columbia University’s Lamont-Doherty Earth Observatory. “And as clouds decrease, that increases the chance of bigger and more intense fires.”

Michael Tippett, a professor of applied mathematics at Columbia, and his colleagues have published research on tornado outbreaks — tornadoes that occur in a bunch — and they did find a trend. “Those bunches are getting bigger,” said Tippett.

“This quasar is ten times brighter in the radio band than any previous object seen in the early universe,” said Zoltan Haiman, a professor of astronomy at Columbia University.

A new report "highlights the urgency for us as a society to reduce greenhouse gas emissions," says Columbia's Radley Horton, "and prepare our most vulnerable communities for some of these climate changes that we're locked into."

We had the science to stop climate change 30 years ago. We didn't. The New York Times takes a look at why we didn't and features research by Columbia scientists Jim Hansen, Wally Broecker, Taro Takahashi, and Adam Sobel.
