Sediment cores from below the Red Sea bolster two key tenets of climate experts, scientists reported Thursday: A three-foot sea level rise in a century is by no means extreme, and once ice sheets start to melt, that process is likely to accelerate for several centuries. Using 500,000-year-old...
Protecting the fragile environment is paramount to the United States and other nations that operate in the Antarctic. The topic of UAVs and their possible effects on the ecosystem were a topic at this year’s Antarctic Treaty Consultative Meeting held in Brasilia, Brazil, according to Polly Penhale...
At opposite ends of the world, trends in sea ice coverage are in stark opposition. Arctic sea ice coverage remains depressed, while Antarctic levels have achieved a record high for the second straight year. Due to warming of the Arctic, the depleted state of Arctic sea ice is expected. The ever-...
German researchers have established the height of the Greenland and Antarctic ice caps with greater precision than ever before. The new maps they have produced show that the ice is melting at an unprecedented rate. The maps, produced with a satellite-mounted instrument, have elevation accuracies to...
WASHINGTON (AP) — Remember the polar vortex, the huge mass of Arctic air that can plunge much of the U.S. into the deep freeze? You might have to get used to it. A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of...
Following a study of satellite data from the past 19 years, researchers found that fresh water from melting glaciers has caused the sea level around the coast of Antarctica to rise by 2 centimeters more than the global average of 6 centimeters. Scientists say the melting of glaciers and the...

The planet's two largest ice sheets – in Greenland and Antarctica – are now being depleted at an astonishing rate of 120 cubic miles each year. That is the discovery made by scientists using data from CryoSat-2, the European probe that has been measuring the thickness of Earth's ice sheets and...
In an icy lake half a mile beneath the Antarctic ice sheet, scientists have discovered a diverse ecosystem of single-celled organisms that have managed to survive without ever seeing the light of the sun. The discovery, reported Wednesday in the journal Nature is not so much a surprise as a triumph...
Over the past few decades, Arctic sea ice has been retreating, and although research shows a downward trend in snow on land in the Arctic, long-term measurements of snow depth on sea ice have been less clear. But now, new research using data from NASA’s Operation IceBridge shows that snow depth on...
Sixteen-foot waves are buffeting an area of the Arctic Ocean that until recently was permanently covered in sea ice—another sign of a warming climate, scientists say. Because wave action breaks up sea ice, allowing more sunlight to warm the ocean, it can trigger a cycle that leads to even less ice...
Arctic sea ice extent continued a rapid retreat through the first two weeks of July as a high pressure cell moved over the central Arctic Ocean, bringing higher temperatures. Antarctic sea ice extent increased rapidly through June and early July, and reached new daily record highs through most of...
The worsening climatic condition and unabated rise in global warming is giving sleepless nights for the global leaders and scientists across the world. The melting of glaciers in Antarctic and Arctic regions is affecting the climatic conditions badly. In a bid to address the urgent issue, a group...
A team of scientists has completed the most accurate and precise reconstruction to date of historic volcanic sulfate emissions in the Southern Hemisphere using multiple ice cores from Antarctica. The new record, described in a paper published this month in the online edition of Nature Climate...
Climate scientists have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. In a paper published this week in the journal Science Express, researchers report that the deep ocean currents that move...
