10 cze 2024 · Color-coded map of the daily sea ice concentration in the Northern Hemisphere for the indicated recent date along with the contours of the 15% edge during the years with the least extent of ice (in red) and the greatest extent of ice (in orange) during the period from November 1978 to the present.
26 sie 2015 · The massive Greenland ice sheet is shedding about 300 gigatons of ice a year into the ocean, making it the single largest source of sea level rise from melting ice. Credits: NASA/Saskia Madlener. Finding the Level. NASA has been recording the height of the ocean surface from space since 1992.
Key Takeaway: Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise. Data from NASA's GRACE and GRACE Follow-On satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower chart) have been ...
3 lut 2023 · The simple and straightforward answer is yes. It is, in fact, melting. But it’s a bit more complicated than that. You can think of ice sheets or Antarctica and Greenland as a bathtub full of water. And we want to know how much is going into that bathtub and how much is coming out.
31 maj 2024 · Clouds, aerosols, even the bumps and dips on the ice itself can play a role. To explore how these factors interact and impact sea ice melting, NASA is flying two aircraft equipped with scientific instruments over the Arctic Ocean north of Greenland this summer.
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.
3 paź 2022 · Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to make ice cover increase. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2022, with a graph overlay.
