This series of videos highlights how NASA Climate Scientists use mathematics to solve everyday problems.  These educational videos to illustrate how math is used in satellite data analysis.

What is the phenomenon of melting sea and land ice?

Ice is found all around our planet, from the highest peak in Africa to the icy North and South Poles.

Why Does NASA Study Ice?

The amount of ice on our planet affects how much energy is absorbed by the Earth's system and also impacts global sea level. These are just some of the reasons why scientists study ice.

Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inch (3 millimeters) in that timeframe alone, according to a major new international climate assessment funded by NASA and ESA (European Space Agency).

The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using these two 2017 maps created using NASA satellite data, have students review the seasonal differences of snow and ice extent.
