Greenland's Melting - 12/8/15

Earth’s ice is expansive. In fact, 10 percent of the planet’s land mass is covered in ice—like glaciers, ice caps and ice sheets—spanning more than 5 million square miles. 

As snowfalls accumulate, melt and refreeze, layer upon layer of dense snow compresses to form ice sheets and glaciers. That ice has played a huge role in our planet’s history, for hundreds and thousands of years shaping the very landscapes we know today.

As chief executive officer, John Racanelli leads a team of 600 full and part-time employees and 1,000 volunteers in pursuing the National Aquarium’s mission to inspire conservation of the world’s aquatic treasures. More than 1.5 million people annually visit the Aquarium’s venue in Baltimore, Maryland, while millions more are touched by the Aquarium’s education programs, outreach activities, social media campaigns and conservation initiatives.
