Geochemical method finds links between terrestrial climate and atmospheric carbon dioxide
2013-04-22 23:36:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Nearly 34 million years ago, Earth underwent a transformation from a warm, high-carbon dioxide "greenhouse" state to a lower-CO2, variable climate similar to the modern "icehouse" world. Massive ice sheets grew across the Antarctic continent, major animal groups shifted, and ocean temperatures decreased by as much as 5 degrees. But studies of how this drastic change affected temperatures on land have had mixed results. Some show no appreciable terrestrial climate change; others find cooling of...

Increased Carbon Dioxide Levels Damage Coral Reefs
2013-04-17 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: Scientists have been worried about coral reefs for years, since realizing that rising temperatures and rising ocean acidity are hard on organisms that build their skeletons from calcium carbonate. Researchers on Australia's Great Barrier Reef are conducting an experiment that demonstrates just how much corals could suffer in the coming decades.

Carbon dioxide removal can lower costs of climate protection
2013-04-12 22:16:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Directly removing CO2 from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial burden on future generations, a study now published by the Potsdam Institute for Climate Impact Research (PIK) shows. It focuses on the use of biomass for energy generation, combined with carbon capture...
