On this episode, TechKnow tags along with NASA's Operation Ice Bridge. As part of a mission based out of Greenland, researchers have to fly a precise path each year and compare measurements of the glacial ice sheet, depth of ice and snow covers, and other data that help track climate change in the Arctic Sea.
With Arctic temperatures rising twice as fast as anywhere else in the world, the annual change due to melting glaciers is often visible to the naked eye—but NASA's flyovers offer a far more specific report of global warming and its impact on rising ocean levels.
