Professor Andreas Muenchow, University of Delaware - The vast, flat expanse stretching into the background is the Petermann Glacier, well over one-third of which has now broken off. It connects the Greenland ice sheet to the Arctic Ocean.
Climate change, population growth and environmental destruction could cause a collapse of the ecosystem just a few generations from now, scientists warned on Wednesday in the journal Nature.
The paper by 22 top researchers said a "tipping point" by which the biosphere goes into swift and irreversible change, with potentially cataclysmic impacts for humans, could occur as early as this century.
From our friends at NASA comes this amazing 26-second video, depicting how temperatures around the globe have warmed since 1880. That year is what scientists call the beginning of the “modern record.” You’ll note an acceleration of those temperatures in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal. The data comes from NASA's Goddard Institute for Space Studies in New York, which monitors global surface temperatures. As NASA notes, “in this animation, reds indicate temperatures higher than the average during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average.”
More than 400 representatives of large institutional investors met Thursday at the United Nations to reconsider climate change from a business perspective on the heels of 5% growth in green energy investment, to $260 billion, in 2011. "The carbon-burning economy is tomorrow's Rust Belt. Your job, it seems to me, is to invest in the Microsofts and Googles of the green economy," Roland Rich, head of the UN Democracy Fund, told investors, who control a collective $26 trillion worldwide. The conference was convened by the UN, the United Nations Foundation and the Ceres coalition.
