Antarctic ice walls protect the climate
by •
Inland Antarctic ice contains volumes of water that can raise global sea levels by several meters. A new study shows that glacier ice walls are vital for the climate, as …read more Source:: Science
Antarctic ice shelves buckle under weight of meltwater lakes
by •
The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its stability. …read more Source:: Science
Antarctic ice shelf ‘sings’ as winds whip across its surface
by •
Winds blowing across snow dunes on Antarctica’s Ross Ice Shelf cause the massive ice slab’s surface to vibrate, producing a near-constant set of seismic ‘tones’ scientists could potentially use to …read more Source:: Science
Ocean waves following sea ice loss trigger Antarctic ice shelf collapse
by •
Storm-driven ocean swells have triggered the catastrophic disintegration of Antarctic ice shelves in recent decades, according to new research published in Nature today. …read more Source:: Science
Decades of satellite monitoring reveal Antarctic ice loss
by •
Scientists have reviewed decades of satellite measurements to reveal how and why Antarctica’s glaciers, ice shelves and sea ice are changing. Their report explains how ice shelf thinning and collapse …read more Source:: Science
Methane-eating microbes may reduce release of gases as Antarctic ice sheets melt
by •
A lake beneath the West Antarctic ice sheet contains large amounts of methane and describes how methane-eating microbes may keep the climate-warming gas from entering the atmosphere. …read more Source:: Science
Antarctic ice rift close to calving, after growing 17km in 6 days, latest data from ice shelf shows
by •
The rift in the Larsen C ice shelf in Antarctica has grown by 17km in the last few days and is now only 13km from the ice front, indicating that …read more Source:: Science
