Sharpening the Picture of Climate Change in the Arctic

In climate studies, the Arctic region is often called "the canary in the coal mine" because it has responded to global warming more extensively than other parts of the planet and more rapidly than predicted. Data from satellite gravity missions can provide an independent view of Arctic region impacts manifested in mass transport processes: melting ice sheets, rising sea level, and changes in ocean currents. Similarly, satellite geodesy has a role to play in monitoring climate change globally.
