Global Warming Forest Destruction Debunked

A new study (Science 12 November 2010: Vol. 330. no. 6006, pp. 957 - 961) refutes global warming tropical rainforest destruction hysteria.

IPCC computer models (inaccurately) suggest (as a “best estimate”) warming over the next century somewhere between 1.8C and 3.6C. Actually, 0.4C is a more reasonable estimate. But, based upon recent studies, even that estimate is likely too high.

The study we’re looking at today examined the Paleocene-Eocene Thermal Maximum (PETM, 56.3 million years ago), a time of “rapid warming” when temperatures in tropical regions “are estimated to have increased by 3° to 5°C”. This was a time when temperatures ranged from roughly 8C to 12C warmer than we see today.

This study reports that (emphasis mine):
“We investigated the tropical forest response to this rapid warming… We observed a rapid and distinct increase in plant diversity and origination rates… The tropical rainforest was able to persist under elevated temperatures and high levels of atmospheric carbon dioxide, in contrast to speculations that tropical ecosystems were severely compromised by heat stress.
In other words, this study found nothing but BENEFITS to this extremely rapid warming and “high levels of atmospheric carbon dioxide”!

Another myth bites the dust -- including the new media meme of a biodiversity crisis.

Well, given the source of the IPCC tropical rainforest hysteria mongering, it should come as no surprise that real science (once again) debunked the purely political and utterly discredited IPCC.
