#Regram #RG @nasaclimatechange: Sea ice helps maintain Earth's temperature, so predicting how the ice extent (a measurement of the area of ocean where there is at least some sea ice) might change helps us understand our warming climate. NASA scientists have developed a new model for better predicting the Arctic’s annual changes.
