What’s in the Forecast and How Do We Know?
The Earth Institute’s International Research Institute for Climate and Society makes probabilistic forecasts for rainfall and temperature for the next six months. How does it do this?

One of Largest Icebergs Ever Breaks off Antarctica
One of the largest icebergs ever – roughly the size of Delaware – just broke off of Antarctica, according to scientists who have been observing the area for years. While it’s not unusual for ice shelves to calve, many in the climate community fear that the breaking of Larsen C may be a signal of…

Deep thoughts from the Deep Blue Sea
The sea is a deep blue, so clear that you might think it was devoid of life. We have seen only a few seabirds circling the ship and playing in the air currents we generate. We haven’t seen any whales or sharks, only an occasional flying fish taking to the air in front of our…

Warming Climate Could Abruptly Increase Rain in Africa’s Sahel
Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying…

As Climate Stirs Arctic Sea Ice Faster, Pollution Tags Along
A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.

Understanding Today’s Climate Politics
The climate problem will be made less bad by technological, cultural, social and economic change that will force political change. Waiting for policy to be the change agent is an exercise in futility.

Christine McCarthy: A Cheerleader for the Physics of Ice
Christine McCarthy, a geophysicist at the Lamont-Doherty Earth Observatory, scrunches blocks of ice between hunks of rock to study how ice behaves under pressure. Her work provides an important piece of the puzzle of how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.
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“
