Environment 1 July 2019 By Adam Vaughan. Global Warming Is Changing the Winds Off Antarctica, Driving Ice Melt. Major Greenland Glacier Is Growing. It is also one of the most active, discharging a tremendous amount of ice from the Greenland Ice Sheet into Ilulissat Icefjord and adjacent Disko Bay—with implications for sea level rise. Recent research found the rate of ice loss from five Antarctic glaciers had doubled in six years and was five times faster than in the 1990s. More information: Alice Marzocchi et al. They used that model to predict how the Greenland and Antarctic ice sheets will speed up their melting in the coming decades. “Still, when considering the 40-y record as a whole, the Antarctic sea ice continues to have a positive overall trend in yearly average ice extents.” 1984? Even though ice is growing this time of year in Antarctica, levels in …
Antarctic sea ice is declining dramatically and we don’t know why . This new NASA/UC Irvine map of ice velocity in Antarctica is 10 times more accurate than any previous map and shows flows over 80% of the continent, where older maps showed about 20%.

Jakobshavn Glacier in western Greenland is notorious for being the world’s fastest-moving glacier. The amount of Antarctic sea ice is … June 6, 2019JPEG. News | July 29, 2019 Flowing Antarctic Ice Mapped 10 Times More Accurately. Global cooling linked to increased glacial carbon storage via changes in Antarctic sea ice, Nature Geoscience (2019). Colored lines indicate direction of flow; background colors show speed.
Far … Antarctic sea ice increased slightly in 2018, but still was the second-lowest since 1979.
