Amazon forests
tlambert | March 13, 2010Back in 2007 a paper, Amazon Forests Green-Up During 2005 Drought, was published in Science:
Coupled climate-carbon cycle models suggest that Amazon forests are vulnerable to both long- and short-term droughts, but satellite observations showed a large-scale photosynthetic green-up in intact evergreen forests of the Amazon in response to a short, intense drought in 2005. These findings suggest that Amazon forests, although threatened by human-caused deforestation and fire and possibly by more severe long-term droughts, may be more resilient to climate changes than ecosystem models assume.…
tlambert | February 3, 2010Jonathan Leake recently wrote a story alleging that the statement in the IPCC AR4 WG2 that up to 40% of the Amazon forest could vanish due to climate change was "bogus". Deltoid can now reveal that Leake deliberately concealed the fact that Dan Nepstad, the author of the 1999 Nature paper cited as evidence for the claim about the vulnerability of the Amazon had replied to Leake's query and informed him the claim was basically correct:
At the time of the IPCC [report], there was ample evidence that a large portion of the Amazon forest is very close to the lower limit of rainfall that is…
