Currently the total sea level rise is about 3 millimeters per year (about 1/8 of an inch per year). Of that amount, about one-third comes from Greenland and Antarctica, one-third from glaciers like those in Alaska or the Himalayas, and one-third from the expansion of seawater as it warms. In the future, we expect Greenland and Antarctica will contribute larger amounts.
The joint U.S.-European mission to study the effects of global warming on the ocean has a new name to honor Michael Freilich, the former head of NASA's Earth Science division.
From 2009 through 2019, NASA’s Operation IceBridge flew above the Arctic, Antarctic and Alaska, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers and ice sheets.
A new study finds that the Greenland Ice Sheet has lost 3.8 trillion tons of ice between 1992 and 2018.
Adapting to rising seas will require a broader understanding of coastal systems, and of human responses to sea-level rise, a new study says.
An elephant seal helps scientists understand how the ocean transports heat between its upper and lower layers — important for estimating how much heat the ocean can absorb.
