New York Times: For hundreds of thousands of years preceding the industrial revolution, the concentration of the greenhouse gas carbon dioxide in the atmosphere didnt exceed 280 parts per million. Now it is poised to pass 400 parts per million, thanks to the burst of fossil fuel combustion and forest clearing thats accompanied humanitys recent growth spurt. That shift was noticed thanks to decades of work by Charles David Keeling of the Scripps Institution of Oceanography and more recently his son Ralph. (Keelings...

Carbon's role in planetary atmosphere formation
2013-04-08 23:30:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A new study in Proceedings of the National Academy of Sciences suggests that the way carbon moves from within a planet to the surface plays a big role in the evolution of a planet's atmosphere. If Mars released much of its carbon as methane, for example, it might have been warm enough to support liquid water. A new study of how carbon is trapped and released by iron-rich volcanic magma offers clues about the early atmospheric evolution on Mars and other terrestrial bodies. The composition of...

Dead forests release less carbon into atmosphere than expected
2013-03-30 10:48:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: Billions of trees killed in the wake of mountain pine beetle infestations, ranging from Mexico to Alaska, have not resulted in a large spike in carbon dioxide released into the atmosphere, contrary to predictions, a UA-led study has found. Massive tree die-offs release less carbon into the atmosphere than previously thought, new research led by the University of Arizona suggests. Across the world, trees are dying in increasing numbers, most likely in the wake of a climate changing toward drier...
