Aug 14, 2024 · 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.
Jan 17, 2024 · From 1985 to 2022, as icebergs fell into the ocean at an accelerating rate, the Greenland Ice Sheet shed about 1,140 billion tons (1,034 billion metric tons) – one-fifth more mass than previously estimated.
Oct 13, 2022 · Warm air temperatures cause melting to occur on the surface of the ice sheet—that process accounts for about half the ice Greenland loses each year.
Oct 18, 2023 · Greenland holds enough ice to raise global sea levels by 7 metres if it were all to melt. The sheet currently loses around 270 billion tonnes of ice each year, and contributes a substantial...
A second late-season melt event occurred later in the month when warm air associated with the aftermath of Hurricane Fiona reached Greenland: on 26 September 2022, the melt area peaked at 15% of the ice-sheet surface (245,000 km 2). Both melt episodes coincided with significant rainfall events.
During September 2022, the Greenland Ice Sheet experienced unprecedented late-season melt events, including surface melt conditions across 36% of the ice sheet surface on 3 September, including at Summit Station (3216 m above sea level in the ice sheet interior).
Nov 21, 2012 · Greenland Ice Sheet Today offers the latest satellite data on surface melting of the Greenland Ice Sheet. Surface melt on the ice sheet results from daily weather conditions that are driven by air temperatures, winds, and feedback effect from changes in the snow or surface dust and soot.
