Greenland's ice is melting faster than scientists previously thought - and this will likely lead to faster sea level rise -thanks to the continued, accelerating warming of the Earth's atmosphere, a new study has found.
For the first time ever, the network of streams, ponds, and lakes across Antarctica's surface have been mapped, and the extent of the water flow is astounding and worrying to scientists.
Laurence Smith, chair of geography at University of California, Los Angeles, deploys an autonomous drift boat equipped with several sensors in a meltwater river on the surface of the Greenland ice sheet on July 19, 2015.

GRACE, twin satellites launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems.
