The Undermining of Climate Science
The election of Donald Trump has climate scientists concerned about its implications for U.S. environmental policies and worldwide efforts to curb the effects of climate change. Many fear that climate science under Trump could be strategically undermined in a variety of ways.

The ‘Bird’ Has Flown!
The ‘bird’ has flown! Voices are raised in celebratory cheers from the southernmost continent to across the U.S. Our first ALAMO float is deployed! Now we can begin to answer some of the big questions on this mysterious ice/ocean interface.

Antarctica Has a New Explorer in the Water Near a Key Ice Shelf
The first of six ALAMO floats parachuted into the Ross Sea off Antarctica to begin profiling the water in a check for areas where warmer than normal water could put the Ross Ice Shelf at risk.

Increasing Tornado Outbreaks: Is Climate Change Responsible?
In a paper published in the journal Science, researchers looked at increasing trends in the severity of tornado outbreaks, measured by the number of tornadoes per outbreak. They found that these trends are increasing fastest for the most extreme outbreaks.

‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet
The Antarctica Peninsula has been referred to as Antarctica’s third ice sheet. Following behind the East and West Antarctic ice sheet in size, one might be inclined to minimize its importance in the effects of melting Antarctic ice, on changes in sea level and other impacts, but that would be an imprudent mistake. The peninsula…

Photo Essay: Where the Trees Meet the Tundra
Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.

Where Trees Meet Tundra, Decoding Signals of Climate Change
In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate…

The Domino Effect
Ice shelves can behave like dominos. When they are lined up and the first one collapses it can cause a rippling effect like dominos. We have seen this with the Larsen Ice Shelves. Named in series, the Larsen A, B and C shelves extended along the northeastern edge of the West Antarctic Peninsula, and covered…

A First Meeting with an Old Friend
If you have studied the impacts of climate on Antarctica you have encountered Pine Island Glacier. Tucked in at an angle under the West Antarctic Peninsula handle, this seemingly innocuous glacier has been making headlines for years as one of the fastest flowing ice stream glaciers on Earth.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
