Antarctic Sea Ice Growth: A Climate Change Paradox

A.J. Rohn

Over the course of the last few years, the growth of Antarctica’s sea ice was well­ documented while the Arctic has experienced ice melt. Different accounts have been given for the paradox at Earth’s poles.

How Continents are Slowing Down Sea Level Rise

Elizabeth Borneman

The continents of earth are helping slow down sea level rise, a new study shows. Melting glaciers and ice sheets are causing sea levels to change around the world, but the continents are actually absorbing a lot of this excess water.

A digital camera on NASA’s ER-2 airplane captured this top-down view of a melt pond atop a glacier in southeastern Alaska on July 16, 2014. Chunks of ice float on the pond’s turquoise water.
