The Global Carbon Budget 2012. The Global Carbon Project’s most recent analysis by scientists from the United States, Norway, Australia, France and the United Kingdom published in the current issue of the journal Nature Climate Change shows that a global economy fueled with coal, oil and natural gas is putting increasing pressure on the global climate system. “Limiting global climate change and all of its consequences is going to require aggressive actions to limit the use of the fossil fuels,” according to Gregg Marland, one of the authors of the paper in Nature Climate Change. Marland, a research professor with Appalachian State University’s Research Institute for Environment, Energy and Economics, is part of the international team analyzing carbon dioxide emissions worldwide.”
