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.

Could Climate Change Shut Down the Gulf Stream?

In the 2004 disaster movie “The Day After Tomorrow,”, global warming accelerated the melting of polar ice, disrupting circulation in the North Atlantic Ocean and triggering violent changes in the weather. Could climate change shut down the Gulf Stream?

Researchers have found the remains of an ancient lakebed off the edge of Antarctica's Pine Island Glacier, on what is now the seafloor. Such lakes lying today under the ice sheet may speed the flow of glaciers. (M. Turrin/Lamont-Doherty Earth Observatory)

Meltwater Lakes Existed Under Antarctic Ice in Ancient Times

In recent years, scientists have discovered hundreds of lakes lying hidden deep beneath the Antarctic ice sheet. Now a team of researchers has found the remains of at least one sub-ice lake that existed when the ice was far more extensive, in sediments on the Antarctic continental shelf.

IRI Unveils Its New Generation of Climate Forecasts

This spring, IRI implemented a new methodology for seasonal temperature and precipitation forecasts. We asked Simon Mason, Andrew Robertson and Tony Barnston, senior climate scientists who lead the development and tailoring of IRI’s forecasts, to answer some fundamental questions about the new forecast.

As rain belts shift due to uneven heating across the globe, wet areas will become wetter and dryer areas dryer, a new study affirms. Here, visitors cross a Panama farm field in a winter downpour. (Kevin Krajick/Earth Institute)

In a Warmer World, Expect the Wet to Get Wetter, and the Dry, Drier

As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.

Vegetation Can Strongly Alter Climate and Weather, Study Finds

A new analysis of global satellite observations shows that vegetation can powerfully alter atmospheric patterns that influence climate and weather.

Richard Seager Sees Hand of Climate Change in Drought

California’s wet and snowy winter brings welcome relief from a years-long drought that has challenged the state’s water supply and agricultural system. But climate scientist Richard Seager of Lamont Doherty Earth Observatory offers words of caution: Remember what happened, because it will happen again.

Lamont Scientists Are Focus of NY Times Multimedia Series

This past winter, reporters from the New York Times went along for the ride with scientists from the Lamont-Doherty Earth Observatory as they flew their mission of discovery over Antarctica.

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 along North America’s East Coast.
