Students throughout Columbia University were notified of a once-in-a-lifetime chance to attend a student simulation in anticipation of the upcoming United Nations Climate Conference in Paris. Two words jumped out at me immediately: climate and Paris.

Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

by | 5.20.2015 at 12:00pm
Increases in westward-blowing winds over the Pacific Ocean are thought to be pushing great masses of water--and heat--through the Indonesian straits, into the Indian Ocean.

Since the late 1990s, global warming has stabilized, even as greenhouse gases have risen. That defies simple models that say the temperature should keep going up. Many scientists think much of the heat trapped in the atmosphere by greenhouse gases is being soaked up and stored by the oceans–at least for now. A team of oceanographers now says they know where it went.

Was Hurricane Sandy the 100-Year Event?

Recent research suggests that Sandy may have been much more likely than previously believed.

Bad Ozone Days in Western U.S. Linked to Pacific Weather

A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.

Smooth Sailing Back to Tasmania

After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.

In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.

A Climate Battle Cry for Earth Day

A group of 17 renowned scientists from around the world are appealing for dramatic action to forestall the worst effects of climate change, issuing an “Earth Statement” that calls for a world powered with zero carbon emissions by mid-century.

Mapping the Seafloor

In addition to depth, we can identify many features in the high-resolution multibeam data that we produce. Most of the seafloor near the shelf break (where the water is between 300 and 500 meters deep) is covered with these irregular furrows that are created when large icebergs are grounded here.

One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and ice streams.

Lamont Strategic Plan

Lamont-Doherty Earth Observatory has been a leader in the study of our planet since its founding 65 years ago. Today, Observatory scientists continue the institution’s long tradition of addressing important questions in the Earth and planetary sciences. 

In a Melting Iceland, Drilling Deep to Stem Climate Change

Underground, carbon dioxide disperses through volcanic basalt, and solidifies into a substance similar to limestone. A geologist shows off a core taken from the injection zone.

Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.
