A new study attributes Antarctica’s brief stabilization to a short term climatic shift that increased precipitation over east Antarctica between 2021 and 2023, adding enough snow to temporarily balance ice loss at the continent鈥檚 edges.

鈥淭he Memory of Darkness, Light and Ice鈥� 鈥� a documentary film featuring Eric Steig, a 蘑菇视频 professor of Earth and space sciences 鈥� tells the story of a U.S. military and research base established in Greenland during the Cold War, and how the samples collected there are driving modern climate science. The film is now available on YouTube, Apple TV and Amazon Prime.
Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from 蘑菇视频 flips the narrative by 90 degrees, pointing instead to winds from the north.
Election recognizes the new member鈥檚 鈥渙utstanding record of scientific and technical achievement and willingness to assist the Academy in providing the best available scientific information and technical understanding to inform complex policy decisions in Washington.鈥澛�
The American Geophysical Union announced Sept. 13 that five 蘑菇视频 faculty members have been elected as new fellows, representing the departments of astronomy, Earth and space sciences, oceanography, global health, and environmental and occupational health sciences.
New research finds that ice-sheet-wide collapse in West Antarctica isn鈥檛 necessarily inevitable. The pace of ice loss varies according to regional differences in atmosphere and ocean circulation.
蘑菇视频 glaciologists are co-authors on two papers that analyzed Antarctic ice cores to understand the continent鈥檚 air temperatures during the most recent glacial period. The results help understand how the region behaves during a major climate transition.
Antarctica鈥檚 next deep ice core, a 1.5-mile core reaching back to 130,000-year-old ice, will be carried out by a multi-institutional U.S. team led by 蘑菇视频’s Eric Steig. The site hundreds of miles from today鈥檚 coastline could provide clues to the most recent collapse of the West Antarctic Ice Sheet.
A new study combines ice cores, geologic records and computer models to understand the past, present and future of the Greenland Ice Sheet. The results show that emissions this century have a big influence on how much ice will be lost from Greenland.
The American Association for the Advancement of Science has named six faculty members from the 蘑菇视频 as AAAS Fellows, according to a Nov. 26 announcement. They are part of a cohort of 443 new fellows for 2019, all chosen by their peers for 鈥渟cientifically or socially distinguished efforts to advance science or its applications.鈥�
A new study by U.S. and U.K. scientists finds that in addition to natural variations in winds that drive warmer water to the West Antarctic Ice Sheet, which last about a decade, there has been a longer-term change in the winds that can be linked with human activities.
A study from the University of Colorado Boulder and the 蘑菇视频 finds that the retreat of the ice sheet covering North America made Antarctic weather more similar from one year to the next.
Ice core records from the two poles show that during the last ice age, sharp spikes in Arctic temperatures triggered shifts in the winds around Antarctica.
Heavier snowfall over Antarctica was supposed to be one of the few brakes on sea-level rise in a warming world. But that prediction is not reliable, says a new study of Antarctic snowfall over the past 31,000 years.
蘑菇视频 glaciologists helped drill the first deep ice core at the South Pole, which will provide new clues to Antarctica’s climate history.
蘑菇视频 glaciologists were part of a team that used a new Antarctic ice core to discover which region triggered sudden global-scale climate shifts during the last ice age.
A 蘑菇视频 researcher is chief scientist this month on a project to drill the first deep ice core at the South Pole, to understand the climate history in that section of Antarctica.
Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.
Detailed ice core measurements show smog-related ratios leveling off in 1970, and suggests these deposits are sensitive to the same chemicals that cause acid rain.
The 蘑菇视频’s new “Future of Ice” initiative includes several new research hires, a new minor in Arctic studies and a free winter lecture series.
A new study in Science, co-authored by the British Antarctic Survey and 蘑菇视频 authors, shows that melting of the floating Pine Island ice shelf is tied to global atmospheric patterns associated with El Ni帽o.
