With warming air temperatures melting the surface of the ice sheet, and warming ocean temperatures causing ocean-terminating glaciers to retreat, Greenland’s ice sheet is a significant contributor to sea level rise.

I don't understand how these surface flows (eg La Nina and the gyres) relate to the warm surface flows shown in the diagram in this article. This alters ocean circulations, and since the ocean and atmosphere are closely tied, the entire climate system is affected. And how much the ice sheets contribute is really dependent on what the climate will do,” says project leader and ice scientist Sophie Nowicki, formerly at NASA Goddard, who joined the UB faculty this semester as Empire Innovation Professor in the Department of Geology, College of Arts and Sciences, and in the UB RENEW Institute. This keeps the ice elevation low and therefore ice loss remains high while the ice sheet retreats. One minor nitpick though: Some things are implied to be new results from this study, but they aren't all that new. It carries a single instrument, the Advanced Topographic Laser Altimeter System (ATLAS), that bombards Earth with laser pulses, each consisting of roughly 300 trillion photons.

What does the global shift in diets mean for climate change? Are the Antarctic and Greenland ice sheets growing or shrinking? But to me, the section is truthful and valuable, irrespective where it came from: it explains to the possibly unfamiliar reader the context and rate of current climate changes in relation to the changes the original study focussed on. We already know that CO2 was the feedback rather than causality of pleistocene glacial cycles. They believe the long observational time frame supports the idea that ice changes are related to long-term climate changes. Current CO2 changes are human caused and are 10,000 times faster than volcanoes. “The Amundsen Sea region in West Antarctica and Wilkes Land in East Antarctica are the two regions most sensitive to warming ocean temperatures and changing currents, and will continue to lose large amounts of ice,” says Hélène Seroussi, an ice scientist at NASA’s Jet Propulsion Laboratory in Southern California who led the Antarctic ice sheet modeling in the ISMIP6 effort. These new results, published this week in a special issue of the journal The Cryosphere, come from the Ice Sheet Model Intercomparison Project (ISMIP6) led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The strength of ISMIP6 was to bring together most of the ice sheet modeling groups around the world, and then connect with other communities of ocean and atmospheric modelers as well, to better understand what could happen to the ice sheets,” says Heiko Goelzer, a scientist from Utrecht University in the Netherlands, now at NORCE Norwegian Research Centre in Norway. This phenomenon could be due to a relatively small increase in snowfall in some regions as a consequence of global warming changing atmospheric circulation, which would be expected on the basis of atmospheric models, Smith and Paolo said, adding that the interior mass increase is much smaller than the mass lost around the peripheries of the ice sheets. A gigaton is 1 billion tons. “Previous altimeters struggled with these challenges. ICESat-2 is a sophisticated piece of hardware. As the water cycle pumps more moisture out of the oceans and into ice sheets, sea levels fall.

If the rebound is instantaneous  the 100 kyear cycle is no longer dominant.

And how much the ice sheets contribute is really dependent on what the climate will do,” said project leader and ice scientist Sophie Nowicki, Ph.D., formerly at NASA Goddard, who joined the University at Buffalo this semester as Empire Innovation Professor in the department of geology in the UB College of Arts and Sciences, and in the UB RENEW Institute. A scientist named Milankovitch came up with the idea in 1941. I think 'surface' here is meant to be the surface of the lithosphere and not the surface of the ice; with this interpretation the abstract is correct. UB helped to facilitate the research by enabling the team to transfer, store and process huge amounts of data at the university’s Center for Computational Research (CCR) as part of a pilot project to leverage the facility’s capabilities to support ice sheet research. Different factors influence average climate over those timescales. An article on CNN featured Siwei Lyu, who spoke about about a new Photoshop tool that could help fight fake images online by making the content producer responsible for making the image trustworthy, rather than leaving it to each individual viewer to sort out. Current climate change is caused by humans. Rather, by adding greenhouse gas emissions into the mix, mean temperatures and sea levels are set to carry on rising - bringing with them a host of, Arctic Sea Ice Minimum Volumes Video - 2020 edition, The Debunking Handbook 2020: Debunk often and properly, 2020 SkS Weekly Climate Change & Global Warming Digest #43, 2020 SkS Weekly Climate Change & Global Warming News Roundup #43, The Debunking Handbook 2020: The elusive backfire effects, Skeptical Science New Research for Week #42, 2020, The Debunking Handbook 2020: Prevent misinformation from sticking if you can, A Skeptical Science member's path to an experiment on carbon sequestration, 2020 SkS Weekly Climate Change & Global Warming Digest #42, 2020 SkS Weekly Climate Change & Global Warming News Roundup #42, The Debunking Handbook 2020: Misinformation is damaging and sticky, The Debunking Handbook 2020: Downloads and Translations, Skeptical Science New Research for Week #41, 2020. 1 receives generous donation, The MolinaCares Accord in New York, Buffalo Olmsted Parks Conservancy team up to promote 'Peace in the Parks', Erie County asks: What are you waiting for? 10 August 2020, News These new results, published this week in a special issue of the journal The Cryosphere, come from the Ice Sheet Model Intercomparison Project (ISMIP6) led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. 18 August 2020, News
