Online news service promotes false climate change study | Environment | guardian.co.uk

An online news service sponsored by the world's premier scientific association unwittingly promoted a study making the false claim that catastrophic global warming would occur within nine years, the Guardian has learned.

Hisas, for her part, said her findings had been endorsed by an Argentine scientist, Osvaldo Canziani, who had worked on the IPCC's fourth assessment report on the state of climate science, and was credited as an adviser to the UEF....

She said the UEF did not intend to withdraw the report. "We are just going to go ahead with it. I don't have a choice now," she said. "The scientist I have been working with checked everything and according to him it's not wrong."

Marshall Hoffman, owner of the PR agency which placed the notice on the AAAS website, argued the a number of recent studies had all shown warming at a much faster rate than predicted by the IPCC in its most recent report. "The thing is, we have already put it on the internet and we had already got a lot of calls on it," he said. "This study is going to be bantered around for months. It doesn't make any difference whether it is released now, or we try to pull it back."

Canziani did not immediately respond to email. Hisas and sources in Buenos Aires said he was ill.

Canziani was co-chair of the IPCC's working group 2, which looked at the effects of climate change.
