Deforestation and global warming

''Deforestation 'not so important for climate change'.
... ecologists reported that carbon emissions from the destruction of tropical forests are probably only half previous estimates.
...
Four years ago, the UN's Intergovernmental panel on Climate Change estimated that deforestation was responsible for up to 20 per cent of CO2 emissions. A more recent study by Richard Houghton of Woods Hole Research Center in Falmouth, Massachusetts, revised that down to 15 per cent for the period 2000 to 2005.
...
But now ecologists at Winrock International, a respected US consultancy based in Arlington, Virginia, whose work was funded by the World Bank and the Norwegian government, says a more detailed analysis puts the figure for 2000 to 2005 at around 8 per cent, with a possible range between 5 and 12 per cent.
