Observing & Predicting
Department:August 28, 2013Maps of changes in the saltiness of the surface waters of the ocean over time can reveal natural climate cycles, human-caused changes in evaporation and rainfall, and variation in the strength and location of currents. This map of changes in surface salinity between 2004 and 2012 provides clues to how climate variabiity and change have influenced the global water cycle in the past decade.
Department:August 27, 2013(video) Chief Meteorologist Jim Gandy, at WLTX in Columbia, SC, earned his reputation as a leading TV meteorologist by giving his viewers what they want: sound science and interesting visuals in a delivery style that's crisp and easy to understand. Recently, Gandy expanded his reports to include locally focused climate science information on topics that directly touch viewers' lives. No controversy here, says Gandy, just good community service.
Department:August 26, 2013On July 30, 2013, a weather station on the southwest coast of Greenland preliminarily set a new record high temperature for the country, but whether it will stand as an "official" record after scientists apply quality control procedures isn't yet known. What is known? Greenland's getting warmer.
Department:August 20, 2013In July 2013, the Pacific Northwest was relatively dry, while the Southeast got a soaking.
Department:August 14, 2013Andrea, Barry, Chantal, Dorian, Erin... who’s next? Probably plenty more, according to NOAA’s updated Atlantic hurricane season outlook. With five named storms already in the books this summer, the 2013 hurricane season is shaping up to be above normal.
Department:August 2, 2013From record-low Arctic sea ice to the highest global sea level of the modern record, the 2012 State of the Climate report provides a complete rundown on the state of Earth's climate and how it is changing.
Department:August 2, 2013The extent of snow-covered ground in the Northern Hemisphere at the end of the cold season (June) hit a record low. Annual average snow cover extent has not exceeded the long-term average even once since 2003. Between 1979 and 2011, the snow cover in June is declining even faster than the end-of-summer Arctic sea ice extent.
Department:August 2, 2013Since 1976, every year has been warmer than the long-term average, and 2012 continued the trend: the global surface temperature ranked among the top 10 warmest years on record.
