Visualize sea ice extent (area of ocean with at least 15 percent sea ice concentration) data for the Arctic and Antarctic. View and compare sea ice extent data for any year or any combination of years from 1979 to present (including near-real-time daily data).
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 losing mass ...
17 Ιουλ 2013 · Interactive: Global ice viewer. Ice, which covers 10 percent of Earth's surface, is disappearing rapidly. Explore this interactive to see how climate change has affected glaciers, sea ice and continental ice sheets worldwide. You can browse a gallery containing this interactive and others here.
Sea and Land Ice Melt landing page. Explore maps, graphs, data, and related education resources. These resources include lesson plans, mini lessons, activities, and datasets for teachers and students.
Graphing Sea Ice Extent in the Arctic & Antarctic. Students create graphs of sea ice extent data for the Arctic and Antarctic, learning about both annual, seasonal cycles and longer-term trends. Visualizations complement the data analysis, allowing students to view animated maps of the data.
Melting ice sheets and glaciers on land add water to the sea. (See the “What’s Causing Sea-Level Rise: Land Ice Vs. Sea Ice” activity for more information about how melting ice contributes to sea level rise.)
•Explain that melting land ice adds to rising seas, while melting sea ice does not. •Observe and explain that warm water molecules expand, taking up more space. •List and consider some real-world solutions for sea level rise.
