Longer term, no doubt that Antarctica is the biggest problem, but I think Greenland is more important this century, and will be impacted by open water as the Arctic melts. In turn, the melt water from Greenland might impact the Gulf Stream. In addition, it looks like conditions in the Arctic influence the jet stream. NASA is doing the appropriately named OMG study of the Greenland melt. Their findings should be pretty interesting. NASA took on an unprecedented study of Greenland’s melting. Now, the data are coming in Back 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 around 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. msn.com
