North Atlantic Current may cease temporarily in the next century

Mon, 12/30/2019 - 07:48
The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations showed that there is a 15 percent likelihood that there will be a temporary change in the current in the next 100 years.

Ancient Mediterranean seawall first known defense against sea level rise and it failed

Wed, 12/18/2019 - 14:35
Ancient Neolithic villagers on the Carmel Coast in Israel built a seawall to protect their settlement against rising sea levels in the Mediterranean, revealing humanity's struggle against rising oceans and flooding stretches back thousands of years.

Ice sheet melting: Estimates still uncertain

Wed, 12/18/2019 - 14:34
Estimates used by climate scientists to predict the rate at which the world's ice sheets will melt are still uncertain despite advancements in technology, new research shows.

New ice river detected at Arctic glacier adds to rising seas

Tue, 12/17/2019 - 14:29
Geologists, examining the desolate Vavilov ice cap on the northern fringe of Siberia in the Arctic Circle, have for the first time observed rapid ice loss from an improbable new river of ice, according to new research.

In ancient Scottish tree rings, a cautionary tale on climate, politics and survival

Tue, 12/17/2019 - 13:15
Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It may have lessons for Brexit-era politics.

November 2019 was 2nd hottest on record for the planet

Mon, 12/16/2019 - 14:15
November 2019 was the second-hottest November for the planet in the 140-year global climate record, according to scientists at NOAA.

Barrels of ancient Antarctic air aim to track history of rare gas

Fri, 12/13/2019 - 08:25
An Antarctic field campaign last winter led by the US and Australia has successfully extracted some of the largest samples of air dating from the 1870s until today. Researchers will use the samples to look for changes in the molecules that scrub the atmosphere of methane and other gases.

Canadian tundra formerly covered in rich forest: Ancient plant fossil record shows

Thu, 12/12/2019 - 15:33
Canada's northernmost islands, Ellesmere and Axel Heiberg islands in Nunavut, were home to a vibrant, temperate forest 56 million years ago, according to fossil research.

High-precision map of Antarctic ice sheet bed topography

Thu, 12/12/2019 - 11:25
Glaciologists have unveiled the most accurate portrait yet of the contours of the land beneath Antarctica's ice sheet -- and, by doing so, have helped identify which regions of the continent are going to be most vulnerable to the impact of future climate warming.

Research confirms timing of tropical glacier melt at the end of the last ice age

Wed, 12/11/2019 - 13:56
Findings on ice retreat across the global tropics clarifies how the low latitudes transformed during the end of the last ice age and can help current-day predictions of our own climate future.

Mountain goats' air conditioning is failing, study says

Wed, 12/11/2019 - 13:56
A new study says Glacier National Park's iconic mountain goats are in dire need of 'air conditioning.'

Scrubbing carbon dioxide from smokestacks for cleaner industrial emissions

Wed, 12/11/2019 - 13:56
Chemistry researchers have uncovered a better way to scrub carbon dioxide from smokestack emissions, which could be a key to mitigating global climate change.

Shrinking of Greenland's glaciers began accelerating in 2000, research finds

Wed, 12/11/2019 - 10:55
Satellite data has given scientists clues about how, when and why Greenland's glaciers are shrinking -- and shows a sharp increase in glacial retreat beginning about 2000, according to new research.

Why polar bears at sea have higher pollution levels than those staying on land

Wed, 12/11/2019 - 07:35
As the climate changes, myriad animal populations are being impacted. In particular, Arctic sea-ice is in decline, causing polar bears in the Barents Sea region to alter their feeding and hunting habits. Bears that follow sea-ice to offshore areas have higher pollutant levels than those staying on land -- but why? A new study reports the likely reasons.

Ice in motion: Satellites capture decades of change

Tue, 12/10/2019 - 10:17
New time-lapse videos of Earth's glaciers and ice sheets as seen from space -- some spanning nearly 50 years -- are providing scientists with new insights into how the planet's frozen regions are changing.

Greenland ice losses rising faster than expected

Tue, 12/10/2019 - 10:17
Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change's high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100.

Could we cool Earth with an ice-free Arctic?

Tue, 12/10/2019 - 10:16
The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. Researchers explored strategies for cooling down the oceans in a world without this important cooling mechanism.

Last remaining glaciers in the Pacific will soon melt away

Mon, 12/09/2019 - 15:13
The last remaining tropical glaciers between the Himalayas and the Andes will disappear in the next decade -- and possibly sooner -- due to climate change, a new study has found. The glaciers in Papua, Indonesia, are ''the canaries in the coal mine'' for other mountaintop glaciers around the world, said one of the researchers.

The Antarctic: Data about the structure of the icy continent

Mon, 12/09/2019 - 12:20
Satellite data from the European Space Agency (ESA) has now been used as the basis for new insights on the deep structure of the continent Antarctica.

Some forests crucial for climate change mitigation, biodiversity

Mon, 12/09/2019 - 12:19
Researchers have identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity.
