2025年1月29日 · Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere. Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice.

The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick and over 3 km (1.9 mi) thick at its maximum. [ 2 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N , near ...

Ice sheet mass loss affects human and natural environments worldwide through coastal erosion, saltwater intrusion, habitat loss, heightened storm surges, tidal flooding, and permanent inundation. The Greenland Ice Sheet has experienced net-annual mass loss for 27 years running, for every year since 1998 (Poinar et al. 2023).

2024年12月25日 · The Greenland Ice Sheet is a single ice sheet or glacier covering about 80 percent of the island of Greenland. It is the largest ice mass in the Northern Hemisphere, globally second in size to only the Antarctic ice mass. It contains 12 percent of the world’s glacier ice and was first crossed by the Norwegian Fridtjof Nansen and his party in ...

The Greenland Ice Sheet (GrIS) is the second-largest contributor of sea-level rise (SLR), after thermal expansion (Zemp et al. 2019). Ice mass loss from the GrIS affects environments and societies worldwide through coastal erosion, saltwater intrusion, habitat loss, increased flooding, and, in some locations, permanent inundation.

6 天之前 · Greenland’s ice is one of the largest contributors to sea level rise, and projecting the speed of the meltdown is a key climate science goal to help people prepare.

2024年1月18日 · Greenland's ice sheet loses about 193 square kilometers of ice per year, researchers found. Study co-author Chad Greene and his colleagues said they qualified the extent of calving, which...

The Greenland ice sheet covers ~1.63 million km 2 and contains ice equivalent to 7.4 m of eustatic sea level rise (Morlighem et al. 2017). Following decades of relative stability, the ice sheet has now lost mass almost every year since 1998, with tied years of record ice loss in 2012 and 2019 (Mankoff et al. 2021).

2024年1月17日 · The Greenland Ice Sheet has shed about one-fifth more ice mass in the past four decades than previously estimated, researchers at NASA’s Jet Propulsion Laboratory in Southern California reported in a new paper. The majority of glaciers on the landmass have retreated significantly, and icebergs are falling into the ocean at an accelerating rate.

3 天之前 · Water from the Greenland Ice Sheet is already the largest global source of sea level rise, accounting for a 0.6-inch (14 millimeters) increase since the 1990s, Thomas Chudley, a glaciologist at ...
