How the Climate System Works
Department:July 15, 2015Scientists estimated global average carbon dioxide concentration at 397.2 parts per million (ppm) in 2014, as the global growth rate of carbon dioxide continues to accelerate.
Department:June 5, 2015Scienitsts find connection between El Niño and fewer spring tornadoes in the south-central United States.
Department:A post for map geeks. How to turn an animation of a year's worth of daily rain maps into a single picture.
Department:April 24, 2015A weak high, a cut-off low, and rapid ocean warming conspired to dump torrential rains in Chile's Atacama Desert in late March 2015.
Department:March 9, 2015Guest blogger Dennis Hartmann makes the case that warm waters in the western tropical Pacific—part of the North Pacific Mode climate pattern—are behind the weird U.S. winter weather of the past two seasons.
Department:February 17, 2015In addition to its primary mission of observing space weather, the Deep Space Climate Observatory (DSCOVR) satellite is carrying two instruments that are important to climate science: the NISTAR radiometer and the EPIC camera.
