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 Sentinel-6 Michael Freilich spacecraft will launch from the U.S. West Coast aboard a SpaceX Falcon 9 rocket in November.
An international effort has generated new estimates of the impact Earth’s melting ice sheets could have on global sea levels by 2100.
To get the best measurements of Earth's atmosphere, you sometimes have to leave it. This November, the Sentinel-6 Michael Freilich spacecraft will do just that.
Researchers have found that the volume of glacial lakes worldwide has increased by about 50% since 1990 as glaciers melt and retreat due to climate change.
Scientists gain new insights into the processes that have driven ocean level variations for over a century.
