By Carol Rasmussen14 May 2015 (NASA/JPL) – A new NASA study finds the last remaining section of Antarctica’s Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and is likely to disintegrate completely before the end of the decade. A team led by Ala Khazendar of NASA’s Jet Propulsion Laboratory in Pasadena, […]
(NASA) – The global concentration of carbon dioxide in the atmosphere – the primary driver of recent climate change – has reached 400 parts per million (ppm) for the first time in recorded history, according to data from the Mauna Loa Observatory in Hawaii. Since 1958, the Mauna Loa Observatory has been gathering data on […]
(NASA) – Sea level rise is caused primarily by two factors related to global warming: the added water coming from the melting of land ice and the expansion of sea water as it warms. This chart tracks the change in sea level since 1993 as observed by satellites. Sea Level Technorati Tags: NASA,sea level,global warming,climate […]
By Clara Chaisson29 January 2015 (OnEarth) – Increasingly intense storms in the United States might have an unexpected origin: Asian air pollution. Researchers from NASA’s Jet Propulsion Laboratory have found that aerosols from across the Pacific strengthen extratropical cyclones—a type of storm system that drives much of our country’s weather. Asia is home to the […]
16 January 2015 (Associated Press) – Federal science officials say that for the third time in a decade, the globe sizzled to the hottest year on record. Both the National Oceanic and Atmospheric Administration and NASA calculated that 2014 was the hottest year in 135 years of record-keeping. Earlier, the Japanese weather agency and an […]
By Jonathan Amos18 December 2014 (BBC News) – NASA’s Orbiting Carbon Observatory (OCO-2) has returned its first global maps of the greenhouse gas CO2. The satellite was sent up in July to help pinpoint the key locations on the Earth’s surface where carbon dioxide is being emitted and absorbed. This should help scientists better understand […]
By Adam Voiland10 December 2014 (NASA) – About 4.5 million years ago, the Kashmir Valley was at the bottom of a large lake, encircled by a ring of rugged mountains. Much of the lake’s water has long since drained away through an outlet channel on the valley’s west side. However, evidence of the lake remains […]
3 December 2014 (AFP) – The melt rate of glaciers in the fastest-melting part of Antarctica has tripled over the past decade, researchers said Tuesday in an analysis of the past 21 years. Glaciers in the Amundsen Sea in West Antarctica are losing ice faster than another part of Antarctica and are the biggest contributor […]
By J. S. Famiglietti 29 October 2014 (Nature Climate Change) – The ongoing California drought is evident in these maps of dry season (Sept–Nov) total water storage anomalies (in millimeter equivalent water height; anomalies with respect to 2005–2010). California’s Sacramento and San Joaquin river basins have lost roughly 15 km3 of total water per year […]
By Patrick Lynch17 November 2014 (NASA) – An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences […]
