"In 2015, in a moment of science communication genius, NASA created a mission called “OMG.” The acronym basically ensured that a new scientific mission — measuring how quickly the Oceans are Melting Greenland — would get maximum press attention.

The subject is actually extremely serious. OMG amounts to a comprehensive attempt, using ships, planes, and other research tools, to understand what’s happening as warm seas creep into large numbers of fjords that serve as avenues into the vast ice sheet — many of which contain large and partly submerged glaciers that are already melting and contributing to sea-level rise.

Greenland is, in fact, the largest global contributor to rising seas — adding about a millimeter per year to the global ocean, NASA says — and it has 7.36 potential meters (over 24 feet) to give. The question is how fast it could lose that ice, and over five years, OMG plans to pull in enough data to give the best answer yet."
