6 wrz 2023 · Most (99.5%) of the permanent ice volume in the world is locked up in ice sheets and glaciers. The Antarctic Ice Sheet is the largest store of frozen freshwater; it would raise sea levels by 57.9 m (its “sea level equivalent”, or SLE) on full melting (BedMachine). The Antarctic Ice Sheet covers 8.3% of the Earth’s land surface.
GLIMS is an international project to inventory the world’s glaciers and to create a comprehensive, global database of land ice through repeat surveys. This data collection’s primary data product is the GLIMS Glacier Database.
Ice, which covers 10 percent of Earth's surface, is disappearing rapidly. Select a topic below to see how climate change has affected glaciers, sea ice, and continental ice sheets worldwide.
GLIMS (Global Land Ice Measurements from Space) is an initiative designed to monitor the world's glaciers primarily using data from the ASTER (Advanced Spaceborne Thermal Emission and reflection Radiometer) instrument aboard the EOS Terra spacecraft, launched in December, 1999.
7 lut 2022 · We use this mapping of glacier flow to generate an estimate of global ice volume that reconciles ice thickness distribution with glacier dynamics and surface topography.
The Global Land Ice Measurements from Space (GLIMS) initiative is an international project to inventory the world's estimated 200,000 glaciers and to create a comprehensive, global database of land ice through repeat surveys.
It provides insights into hotspots for changes in freshwater storage and highlights the crucial role and vulnerability of the cryosphere (snow and ice). The report shows how large areas of the globe recorded drier than normal conditions in 2021 - a year in which precipitation patterns were influenced by climate change and a La Nia event.
