Our magnificent planet is always ready for its close-up. For Earth Day, NASA wants to see your take.

How can NASA sea-level science be placed in the hands of decision-makers? Some of the answers began to take shape recently at the Chesapeake Bay.

Glaciers wax and wane over 122,000 years in a new animation from software engineers at NASA-JPL.

Formerly the island's fastest-flowing glacier, Jakobshavn Glacier slowed dramatically when a nearby ocean current cooled, though it's still adding to global sea level rise.

As it takes to the field for the fourth year in a row, NASA's Oceans Melting Greenland (OMG) mission has proven that when it comes to the world's largest island, we still have a lot to learn.

New observations and more powerful computer models allow scientists to peer beneath the ice of Greenland and Antarctica.
