      Is Agriculture the New Global Warming Bad Guy?
      This is true for the polar or boreal forest, where bare ground is white for much of the year, and growing activity is low so little CO2 is taken up (but it is moot for high latitude forests because no one is cutting them down). However, removal of tropical or equatorial forests *will* increase the global temperature because of the lost CO2 *removal* ability (they are actively growing year-round), and because the brightness difference between foliage and dirt is not that large. Burning any kind of forest down is of course even worse, because it directly increases the atmospheric CO2. This was presented in a talk at the December AGU meeting in San Francisco and, I think, can also be found in the Nobel Prize winning IPCC report: www.ipcc.ch/index.htm (I can't find it immediately but there's lots of other good stuff there).
