Researchers Model Differences in East Coast Sea Level Rise
For years, scientists have been warning of a so-called “hot spot” of accelerated sea-level rise along the northeastern U.S. coast. But accurately modeling this acceleration as well as variations in sea-level rise from one region to another has proven challenging. Now new research offers the first comprehensive model for understanding differences in sea level rise…

Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice
An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.

State of the Arctic: Longer Melting Seasons, Thinning Sea Ice
The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. Lamont-Doherty Earth Observatory’s Marco Tedesco describes the changes underway.

In Greenland, Exactly Where Meltwater Enters the Ocean Matters
In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.

The Damaging Effects of Black Carbon
Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.

A Prize-Winner Explains His Work
Nicolás Young studies glaciers and ice sheets, and how they’ve changed in the past. His work earned him the Blavatnik Award for Young Scientists last fall, which came with a $30,000 prize. You can hear him talk about his research in this new video, produced by the Blavatnik Family Foundation.

Greenland Glaciers Retreating Faster than Any Time in Past 9,500 Years
A new study uses sediment cores to track the expansion and retreat of glaciers through time, and finds that they are retreating quickly and are more sensitive to temperature change than previously realized.

Melting Ice, Suntanned Rocks and an Award-Winning Postdoc
Nicolás Young was just named a winner of a 2015 Blavatnik Award for his work measuring ice sheets in changing climates of the past. His new projects are taking glacier tracking to the next level.

The Changing Upernavik Waterfront
Project Background: Changing conditions in Greenland’s northwest glaciers over the last decade have led to a range of questions about water temperature and circulation patterns in the fjords where ocean water meets the glacial fronts.
