Ocean Acidification Could Amplify Global Warming, Study Says
2013-08-26 18:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: The increasing acidification of the worlds oceans caused by rising concentrations of atmospheric carbon dioxide not only poses a threat to marine creatures, but also could lead to an intensification of planetary warming, according to a new study. A team of U.S., British, and German researchers conducted experiments in seawater enclosures, known as mesocosms, showing that the increasing acidification of the ocean leads to a drop in production of an important sulfur compound, dimethylsulphide, or...
Krill face greater risks in warming Antarctic waters

Climate News Network: They may not look very appetizing, but they are what sustains much of the marine life in the southern ocean. Antarctic krill, usually less than 2.36 inches long, are the primary food source for many species of whale, seal, penguin and fish. Krill, the foundation of the Antarctic marine food chain, may be at a greater risk in warmer seas. But there's a problem: the waters round Antarctica are warming, and it looks as if they will probably continue to do so. If they do, a team of UK researchers...

Science points to new global warming source: sea
2013-08-25 15:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Oceans that grow more acidic through Man's fossil fuel burning emissions, can amplify global warming by releasing less of a gas that helps shield Earth from radiation, a study said today. And the authors warned the potentially vast effect they uncovered is not currently factored into climate change projections. Scientists say that Man's carbon dioxide (CO2) emissions contribute to planetary warming by letting the Sun's heat through the atmosphere but trapping heat energy reflected back from...

Rising ocean acidity will exacerbate global warming
2013-08-25 12:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature: The slow and inexorable increase in the oceans acidity as they soak up carbon dioxide from the atmosphere could itself have an effect on climate and amplify global warming, according to a new study. Acidification would lead certain marine organisms to emit less of the sulphur compounds that help to seed the formation of clouds and so keep the planet cool. Atmospheric sulphur, most of which comes from the sea, is a check against global warming. Phytoplankton -- photosynthetic microbes that drift...

Al Gore explains why hes optimistic about stopping global warming
2013-08-21 21:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Ezra Klein: In 2005, when An Inconvenient Truth came out, I remember that the hope was we could keep the carbon load in the atmosphere to 350 parts per million, and the fear was we would hit 400ppm. Now weve hit 400ppm and people are hoping to avoid 450ppm. This seems to be getting out of hand, and fast. Al Gore: We have already crossed the 400 parts per million mark. We crossed it earlier this year. The question now is how high it will go before we begin bending the curve. But in spite of...
