Video from NASA of the Arctic ice disappearing
Arctic sea ice has not only been shrinking in surface area in recent years, it’s becoming younger and thinner as well. In this animation, where the ice cover almost looks gelatinous as it pulses through the seasons, cryospheric scientist Dr. Walt Meier of NASA Goddard Space Flight Center describes how the sea ice has undergone fundamental changes during the era of satellite measurements.
(CNN) From year to year, the ice around the Arctic ebbs and flows, reaching a minimum and maximum as the temperature shifts through the seasons.
Scientists recently released time-lapse animation comparing Arctic sea ice since 1984 with now, and it is a little startling. The old sea ice - the Arctic sea ice that lasts year after year - is smaller than it has been in three decades.
