IPCC quotes WWF (again) … gets it wrong (again)

IPCC's primary source of alarmism

Peer-review, schmeer-review. Half of the IPCC’s last report was based on stuff like this, papers from deep green advocacy groups like WWF which happened to fit nicely with the IPCC’s pre-conceived agenda of climate alarmism. And they’ve been caught with their pants down yet again, this time on the sensitivity of Amazon rainforests to decreased rainfall:

A new NASA-funded study has concluded that Amazon rain forests were remarkably unaffected in the face of once-in-a-century drought in 2005, neither dying nor thriving, contrary to a previously published report and claims by the Intergovernmental Panel on Climate Change.

“We found no big differences in the greenness level of these forests between drought and non-drought years, which suggests that these forests may be more tolerant of droughts than we previously thought,” said Arindam Samanta, the study’s lead author from Boston University.

The IPCC is under scrutiny for various data inaccuracies, including its claim — based on a flawed World Wildlife Fund study — that up to 40% of the Amazonian forests could react drastically and be replaced by savannas from even a slight reduction in rainfall.

“Our results certainly do not indicate such extreme sensitivity to reductions in rainfall,” said Sangram Ganguly, an author on the new study, from the Bay Area Environmental Research Institute affiliated with NASA Ames Research Center in California.

“The way that the WWF report calculated this 40% was totally wrong, while [the new] calculations are by far more reliable and correct,” said Dr. Jose Marengo, a Brazilian National Institute for Space Research climate scientist and member of the IPCC.

  2. […] The anti-human scaremongers at the WWF fed their friends at the IPCC some data about Amazonian rainforests, which ended up in the AR4 report.  Of course, it’s total junk. […]
