Crippled Atlantic Conveyor Linked to Ice Age Climate Change - Science

Thu, 06/30/2016 - 14:55
Slowdowns of the Atlantic meridional overturning circulation have long been suspected as a cause of the climate swings during the last ice age, but never definitively shown, until now. The new study “is the best demonstration that this indeed happened,” says Lamont's Jerry McManus.

Antarctic Sea Ice Affects Ocean Circulation - Europa Press

Tue, 06/28/2016 - 12:00
A new study led by Lamont's Ryan Abernathey shows how sea ice migration around Antarctica be more important for global ocean overturning circulation than previously thought. (In Spanish)

Predictions of More Blazing Heat, Drought and Fires in the West - Washington Post

Thu, 06/23/2016 - 12:00
The burning sensation in the southwestern United States was diagnosed by climate scientists more than a year ago, the Washington Post writes. The Post cites research by Lamont-Doherty scientist Park William into connections between the California drought and climate change.

California Firefighters Wrangle With Dead Trees - KQED

Wed, 06/22/2016 - 12:00
California's overworked firefighters are being forced to take on another task — clearing dead and dying trees. John Upton talks with Lamont's Park Williams about the role of drought and rising temperatures.

Greenland's Vast Melt and Its Influence on Atlantic Circulation - Washington Post

Mon, 06/20/2016 - 12:00
High-resolution ocean models that can capture eddies are extremely important for understanding the fate of freshwater in the sea around Greenland, says Lamont's Marco Tedesco.

Water Vapor vs Carbon Dioxide: Which 'Wins' In Climate Warming? - Forbes

Mon, 06/20/2016 - 11:33
The fact that water vapor is the dominant absorber in the Earth’s greenhouse effect can lead to a flawed narrative about the role of anthropogenic carbon dioxide (CO2) as driver of climate warming. Lamont's Adam Sobel helps explain.

Sea Ice Retreat May Accelerate Greenland Melting - Science

Fri, 06/17/2016 - 11:30
Last summer the northern parts of the Greenland Ice Sheet experienced record melting as summer temperatures rose as high as 66°F. Now, a group of scientists led by Lamont's Marco Tedesco has linked the melt pattern with a high-pressure vortex, known as a block, that loitered north of the island during June and July 2015, wreaking weather havoc. Some researchers say such atmospheric blocks are expected to result from melting sea ice.

The Weird Weather that Entrenched California's Drought - Climate Central

Tue, 06/14/2016 - 12:28
Climate change has pushed up average temperatures by nearly 2°F worldwide. Most of California was warmer than that from March through May, with some patches of the state more than 4°F warmer than average. “This does not look like a typical El Niño year out West,” said Lamont's Ben Cook.

Globalized Economy More Susceptible to Weather Extremes, Scientists Warn - Reuters

Fri, 06/10/2016 - 17:44
The globalization of the world's economy this century has made it far more vulnerable to the impacts of extreme weather, including heat stress on workers, according to a new study from Lamont's Anders Levermann.

Warmer Arctic, Melting Glaciers Accelerating Greenland Ice Loss - CBC

Fri, 06/10/2016 - 12:00
2015 was a record year for high temperatures and melting glaciers in western Greenland, an effect that is amplifying itself and could lead to accelerated warming in the Arctic, new research from Lamont's Marco Tedesco explains.

A New Solution to Carbon Pollution? - Science

Thu, 06/09/2016 - 18:03
Researchers working in Iceland, including Lamont's Martin Stute, say they have discovered a new way to trap the greenhouse gas carbon dioxide deep underground by changing it into rock.

Martin Stute: Putting CO2 Away for Good by Turning It to Stone - The Conversation

Thu, 06/09/2016 - 17:00
Lamont's Martin Stute writes about the CarbFix project in Iceland, where he has been working with other scientists and engineers to capture CO2 emissions and create permanent storage by turning CO2 to stone.

Iceland Carbon Dioxide Storage Project Locks Away Gas, and Fast - New York Times

Thu, 06/09/2016 - 16:20
Lamont scientists have come up with a way to store carbon dioxide that dissolves the gas with water and pumps the resulting mixture — soda water, essentially — down into certain kinds of rocks, where the CO2 reacts with the rock to form a mineral called calcite. By turning the gas into stone, scientists can lock it away permanently.

Weird Jet Stream Behavior Could Be Making Greenland's Melting Even Worse - Washington Post

Thu, 06/09/2016 - 16:00
Reanalyzing Greenland's last melt season, Lamont's Marco Tedesco found something odd and worrying. Greenland had shown much more unusual melting in its colder northern stretches than in the warmer south, and that this had occurred because of very strange behavior in the atmosphere above it.

Is Wacky Weather Helping Melt Greenland? - Science

Thu, 06/09/2016 - 15:24
A new analysis of the Greenland Ice Sheet led by Lamont's Marco Tedesco points to an underappreciated culprit that could accelerate the melting of the Greenland ice sheet: wind.

Iceland Carbon Capture Project Quickly Converts Carbon Dioxide Into Stone - Smithsonian Magazine

Thu, 06/09/2016 - 14:27
A pilot in Iceland project that sought to demonstrate that carbon dioxide emissions could be locked up by turning them into rock appears to be a success. Smithsonian Magazine talked with Lamont's Juerg Matter, who has been involved in the project, and Dave Goldberg.

Climate Change Could Force Huge Migrations Near the Equator - Washington Post

Thu, 06/09/2016 - 12:00
New research from Lamont's Adam Sobel and alumnus Solomon Hsiang suggests that even a moderate amount of warming could force populations in the tropics to undergo huge migrations — longer journeys than they would have to take if they lived anywhere else on the planet.

Study Links Greenland Melting with 'Arctic Amplification' - UPI

Thu, 06/09/2016 - 10:43
New research led by Lamont's Marco Tedesco links Greenland's 2015 record temperatures and melting with the phenomenon known as Arctic amplification.

Arctic's Melting Ice Creates Vicious Warming Circle - USA Today

Thu, 06/09/2016 - 05:58
As Arctic sea ice hit a record low, scientists led by Lamont's Marco Tedesco announced the first link between melting ice in Greenland and a phenomenon known as Arctic amplification, the faster warming of the Arctic compared to the rest of the Northern Hemisphere.

The See-Through Sea - The Economist

Tue, 06/07/2016 - 12:00
The pioneering maps put together by Lamont's Marie Tharp and Bruce Heezen in the 1950s and 1960s, which first identified the structure of the mid-Atlantic ridge, were mind-expandingly right in their synoptic vision. The Economist looks at the challenges then and now of mapping the sea floor.
