Artificial removal of atmospheric carbon dioxide may do little to save the oceans
2015-08-04 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
International Business: There is no plan B, U.S. President Barack Obama said on Monday, while unveiling an ambitious plan to reduce domestic greenhouse gas emissions and mitigate the effects of climate change. Now, a new study -- which analyzed proposals to artificially suck out carbon dioxide from the atmosphere -- has backed Obamas assertion, and reaffirmed the need to act before its too late. Artificial carbon dioxide removal (CDR) from the atmosphere has been proposed to reduce both risks to marine life ......
Deeper Ocean Waters Absorbed Much Excess Atmospheric Heat
2015-07-10 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment 360: The waters of the Western Pacific and Indian Ocean warmed significantly from 2003 to 2012, but most of the heat is being stored at depth rather than near the surface, NASA researchers explained this week in the journal Science. The findings shed light on mechanisms behind the so-called global warming "hiatus," in which air temperatures appeared to rise more slowly from 2003 to 2012. Warming in the Western Pacific and Indian Ocean during that period started to appear at roughly 32 feet below the surface,...

Variations in atmospheric oxygen levels shaped Earth's climate through the ages
2015-06-11 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously overlooked factor, a new University of Michigan-led study concludes. Oxygen currently comprises about 21 percent of Earth's atmosphere by volume but has varied between 10 percent and 35 percent over the past 541 million years. In periods when oxygen levels declined, the resulting drop in atmospheric density...
