BD 22: The Growing And Shrinking Ice Of Antarctica

NASA

This week, we look at the ice sheets of Antarctica. Like so much of the world's ice, a lot of it is melting away and shrinking. But there are certain places in Antarctica that the ice is actually increasing. How? Why? Better ask a scientist.  

Or how about three? Son Nghiem, Eric Larour and Ala Khazendar give us the scoop on how scientists gather this crucial data, and what it's telling them about our changing climate.

Dave Schlom is the longtime host and creator of Blue Dot. From surfing to Voyager in interstellar space, rock guitar to orcas in our imperiled oceans, the topics on Blue Dot are as varied as the host’s interests and connections -- which are pretty limitless! An internationally respected space history journalist, Dave is also deeply fascinated by all aspects of the grand workings of nature’s awesome machinery on scales ranging from galactic to subatomic. And topics take in all aspects of the arts and sciences.
