By Ari Phillips 10 July 2015 (Climate Progress) – A major new analysis on the impact melting polar ice sheets could have on sea level rise has given rise to some worrisome conclusions. Researchers found that sea levels increased some 20 feet during three warming periods of 1.8 to 3.6°F (1 to 2°C) that took […]
By Laura Rocchio2 July 2015 (NASA) – Researchers and citizens have known for some time that Turkey’s glaciers are shrinking. Now scientists have calculated the losses and found that more than half of the ice cover in this mountainous country has vanished since the 1970s. A team of researchers from Ege University (Turkey) and NASA’s […]
By Chris Mooney 25 June 2015 (Washington Post) – If Greenland goes, it is becoming clear that it won’t go quietly. Scientists have already documented entire meltwater lakes vanishing in a matter of hours atop the vast Greenland ice sheet, as huge crevasses open beneath them. And now, they’ve cast light on the mechanisms behind […]
By Rachael Rhodes28 May 2015 CORVALLIS, Oregon (OSU) – A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect – they increased the production of methane in the tropical wetlands. Usually increases in methane levels […]
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, […]
By Joby Warrick11 May 2015 (Washington Post) – Global sea levels are climbing at a faster rate than previously thought, according to a new analysis that underscores scientists’ concerns about the impact of melting glaciers and ice sheets near the Earth’s poles. The new research published Monday in the journal Nature Climate Change shows that […]
By Tanya Lewis24 April 2015 (Business Insider) – Earth Day, which was on April 22 this year, is a time to celebrate and protect the pale blue dot we call home. But some of its crown jewels may be vanishing. Many parts of the globe face threats from warming temperatures, sea level rise, drought, and […]
By Bill Weir9 April 2015 (CNN) – The world’s glaciers are disappearing. Climate change skeptics are not. The people who study our oceans and skies worry about both of these phenomena. But in wide swaths of 21st century America, the argument is still stuck on what to call the other side. “Denier” can also describe […]
CORVALLIS, Oregon, 19 March 2015 (OSU) – Incessant mountain rain, snow and melting glaciers in a comparatively small region of land that hugs the southern Alaska coast and empties fresh water into the Gulf of Alaska would create the sixth largest coastal river in the world if it emerged as a single stream, a recent […]
(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 […]
