New Radar Technique Lets Scientists Probe Invisible Ice Sheet Region on Earth and Icy Worlds

一种新的雷达技术开发的毕业学生ent allows imaging of the upper few feet of ice sheets on Earth and icy worlds. The technique uses instruments on airplanes or satellites to survey large regions quickly. The upper few feet of ice ...

Shrinking Arctic Glaciers Are Unearthing a New Source of Methane

As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new ...

Tracking Ships' Icy Paths Amidst Climate Change

Understanding when and where ships are entering areas of Arctic sea ice can help elucidate the potential impacts of vessel traffic in the ...

Polar Ice Sheet Melting Records Have Toppled During the Past Decade

The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The seven worst years for ...

A Once-Stable Glacier in Greenland Is Now Rapidly Disappearing

As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now retreating at an unprecedented rate, according to a new ...

Less Ice, Fewer Calling Seals

For several years, a team of researchers used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings indicate that sea-ice retreat has had significant effects ...

Researchers Correlate Arctic Warming to Extreme Winter Weather in Midlatitude and Its Future

A warmer Arctic has been linked to extreme winter weather in the midlatitude regions. But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data ...

Ice Sheets Can Collapse Faster Than Previously Thought Possible

Ice sheets can retreat up to 600 meters a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured. An international team of researchers used ...

Deep Ocean Currents Around Antarctica Headed for Collapse, Study Finds

Antarctic circulation could slow by more than 40 per cent over the next three decades, with significant implications for the oceans and the ...

The Greenland Ice Sheet Is Close to a Melting Point of No Return

A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to ...

3000 +数十亿吨的冰块从南极冰Sheet Over 25 Years

Scientists have calculated that the fastest changing Antarctic region?-?the Amundsen Sea Embayment?-?has lost more than 3,000 billion tonnes of ice over a ...

3D Radar Scan Provides Clues About Threats to Iconic Alaskan Glacier

Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal ...

Entire Populations of Antarctic Seabirds Fail to Breed Due to Extreme, Climate-Change-Related Snowstorms

The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs. However, from December 2021 to January ...

Arctic Climate Modelling Too Conservative

Climate models used by the UN's IPCC and others to project climate change are not accurately reflecting what the Arctic's future will be, experts ...

Robot Provides Unprecedented Views Below Antarctic Ice Shelf

在一个水下机器人的帮助下,被称为冰fin, a U.S.- New Zealand research team has obtained an unprecedented look inside a crevasse at Kamb Ice Stream -- revealing more than a century of ...

Satellites Observe Speed-Up of Glaciers on the Antarctic Peninsula

Glaciers -- giant blocks of moving ice -- along Antarctica's coastline are flowing faster in the summer because of a combination of melting snow and warmer ocean waters, say researchers. On ...

Keeping Drivers Safe With a Road That Can Melt Snow, Ice on Its Own

Slipping and sliding on snowy or icy roads is dangerous. Salt and sand help melt ice or provide traction, but excessive use is bad for the environment. And sometimes, a surprise storm can blow ...

Acceleration of Global Sea Level Rise Imminent Past 1.8 Degrees Planetary Warming

A study shows that an irreversible loss of the ice sheets, and a corresponding acceleration of sea level rise, may be imminent if global temperature cannot be stabilized below 1.8 degrees ...

Record Low Sea Ice Cover in the Antarctic

There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometers of the ...

More Frequent Atmospheric Rivers Hinder Seasonal Recovery of Arctic Sea Ice

The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called ...

Wildfires Are Increasingly Burning California's Snowy Landscapes and Colliding With Winter Droughts to Shrink California's Snowpack

A research team examined what happens to mountain snowpacks when sunny, midwinter dry spells occur in forests impacted by severe ...

Global Warming Reaches Central Greenland

A temperature reconstruction from ice cores of the past 1,000 years reveals that today's warming in central-north Greenland is surprisingly pronounced. The most recent decade surveyed in a ...

Study Offers Most Detailed Glimpse Yet of Planet's Last 11,000 Summers and Winters
