The results of what researchers say is the longest-running study of Antarctica‘s ice mass have been published, and they are dramatic. Yearly ice loss has increased by a factor of six in the past 40 years, contributing more than half an inch to global sea level rise, a University of California, Irvine (UCI) press release […]
By Marlene Cimons Researchers monitoring vibrations from Antarctica‘s Ross Ice Shelf were flabbergasted not long ago to hear something unexpected—the ice was “singing” to them. “We were stunned by a rich variety of time-varying tones that make up this newly described sort of signal,” said Rick Aster, professor of geosciences at Colorado State University, one […]
Greenpeace is on a mission to create the largest protected area on earth in Antarctica, and it just gained a very talented ally to help promote that goal. Radiohead frontman Thom Yorke released a single Tuesday in support of the campaign called “Hands Off Antarctica,” The Guardian reported. “There are some places on this planet […]
In the past few decades, the Southern Ocean surrounding Antarctica has gotten less salty and has warmed at roughly twice the rate of global oceans overall. Now, in a new study, scientists found convincing evidence that these trends are the result of two human influences: climate change from greenhouse gas emissions and the depletion of […]
NASA will soon activate the “most advanced laser instrument of its kind” to study Earth’s changing polar ice. The incredibly precise Advanced Topographic Laser Altimeter System (ATLAS) is the main feature of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) that successfully launched into space from the Vandenberg Air Force Base in California on Sept. […]
A section of the East Antarctic Ice Sheet that contains three to four meters (approximately 10 to 13 feet) of potential sea level rise could melt if temperatures rise to just two degrees above pre-industrial levels, a study published in Nature Wednesday found. Researchers at Imperial College London, the University of Queensland, and other institutions […]
In two recent studies, scientists have looked into the future and into the past to see what might happen to the global climate if we fail to curb greenhouse gas emissions in time. The results are frightening. A study published Monday in Proceedings of the National Academy of Sciences examined how, once a certain threshold […]
By Daisy Dunne Scientists studying the troposphere—the lowest level of the atmosphere—have found “powerful evidence” that climate change is altering seasonal temperatures. A study published in Science finds that climate change has caused an increase in the difference between summer and winter temperatures across North America and Eurasia over the past four decades. This could […]
The five companies responsible for 85 percent of krill fishing in Antarctica announced Monday that they would put a “voluntarily permanent stop” to fishing in vulnerable areas earmarked by conservationists for the world’s largest ocean sanctuary, the Guardian reported. Krill are an important food source for iconic Antarctic marine life like whales, seals and penguins. […]
