A Focus on the Thinning Northwest Greenland Glaciers
Blog by Hakim Abdi, LDEO Satellite measures showing thinning ice on the Northwest Greenland glaciers prompted Operation IceBridge to include annual flights over this region. The area runs along the Baffin Bay coast, which is often covered in fog and low lying clouds forcing delays and reschedules. With the end of our season in sight…

Switchyard Project: Melting Ice, a Fresher Arctic
The freshwater content of the Arctic Ocean is increasing as the Earth’s climate warms. Chemical analysis indicates that the source is both melting ice and the Pacific Ocean.

The American Climate Gap
There’s a growing gap between scientists’ view of climate change and that of the general public, and it has less to do with scientific “illiteracy,” and more to do with the psychology of how people frame their understanding of the world, say the authors of a paper just published in the journal American Psychologist.

Witnessing time – from 445 million year old rocks exposed in the Fjords to ~4 thousand year old small ice caps
By Hakim Abdi, LDEO. My first flight on the P3 and the scenery was nothing short of breathtaking. The science mission involved flights in the north over the Steensby glacier that passes through Sherard Osbron Fjord, and Ryder glacier constrained by the Victoria Fjord. In northeast Greenland we overflew the Hagen glacier and the Flade…

Earth, Water and Sky –A Conversation with Pierre Gentine, a new Columbia Water Center Scientist
Columbia Water Center welcomes Pierre Gentine, Assistant Professor of Applied Mathematics at Columbia University’s School of Engineering and Applied Science, as an affiliate researcher. Pierre’s groundbreaking research on the way soil moisture interacts with the atmosphere has implications for many of CWCs initiatives—from developing more efficient irrigation systems, to water resource management, to understanding floods.…

Switchyard Project: New Sampling Record
On May 10, we celebrated the sampling of our 10th station yesterday. These are more stations than we were ever able to get water samples from. Because of the ongoing good weather, we will certainly get one more station today, and hopefully many more during the next couple of days. So watch the posted video and celebrate with…

Switchyard Project: Sampling Success
The past 1½ weeks have been very successful. Our team from Lamont-Doherty Earth Observatory was able to obtain water samples from eight stations, while the team from the University of Washington has already broken their all-time record of the past years of 18 stations. Today (May 7) is actually the first day we can’t fly…

Switchyard Project: Rescue Operation
Four people who tried to ski from the North Pole to Greenland got stuck on the ice and ran out of food. Since our team was out on the ice for sampling close to their location, we stopped sampling and picked them up.

Switchyard Project: It’s all about the weather
One can only imagine what kind of a pilot one has to be to fly in the arctic regions and land on sea-ice under weather conditions as we have experienced already – fog above the ice and clouds covering the area with very low visibility.
Congratulations to our Columbia Climate School Class of 2026 and all of our 2026 Columbia University graduates! Learn more about our May 15 Climate School Class Day celebration. 💙 #Columbia2026 #ColumbiaClimate2026
