Antarctica & Greenland Losing Ice at Fastest Rate Ever Recorded
Posted by Environment 360: None Given on August 21st, 2014
Environment 360: Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per year — enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick — according to German researchers. Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing...

Environment 360: Trees are saving more than 850 human lives each year and preventing 670,000 cases of acute respiratory symptoms in the U.S., according to the first broad-scale estimate of trees' air pollution removal by U.S. Forest Service researchers. Looking at four common air pollutants -- nitrogen dioxide, ozone, sulfur dioxide, and particulate matter with a diameter less than 2.5 microns -- researchers valued the human health benefits of the reduced air pollution at nearly $7 billion annually in a study published...
NASA Image of Alaska Depicts Spring-like Temperatures and Thaw

Environment 360: NASA Earth Observatory Alaska’s warm January As the continental U.S. faced frigid weather and major winter storms in January, Alaska experienced record high temperatures. A map based on NASA satellite data shows that the last half of January was one of the warmest winter periods in Alaska’s history, with temperatures as much as 40 degrees F (22 C) above normal on some days in the central and western portions of the state. A high pressure system off the state's western coast sent warm air and rain...
