The Impact of Agricultural Soil Erosion on the Global Carbon Cycle

K. Van Oost, T. A. Quine, G. Govers, S. De Gryze, J. Six, J. W. Harden, J. C. Ritchie, G. W. McCarty, G. Heckrath, C. Kosmas, J. V. Giraldez, J. R. Marques da Silva, and R. Merckx
Science 26 October 2007: 626-629.
A survey of agricultural soil erosion across the United States and Europe implies that such erosion provides at most a small sink for CO₂ and thus cannot offset emissions. Abstract »|   Full Text »|   PDF »|   Supporting Online Material »|  

Why Is Climate Sensitivity So Unpredictable?

Gerard H. Roe and Marcia B. Baker
Science 26 October 2007: 629-632.
The possibility that doubling atmospheric CO₂ levels may increase global temperatures more than the expected 3 to 5 degrees Celsius is inherent in the climate system and can never be ruled out. Abstract »|   Full Text »|   PDF »|   Supporting Online Material »|
