Climate Change Study Had 'Significant Error'

WASHINGTON (AFP) – A climate change study that projected a 2.4 degree Celsius increase in temperature and massive worldwide food shortages in the next decade was seriously flawed, scientists said Wednesday.

The study was posted on the website of the American Association for the Advancement of Science and was written about by numerous international news agencies, including AFP.

But AAAS later retracted the study as experts cited numerous errors in its approach.

"A reporter with The Guardian alerted us yesterday to concerns about the news release submitted by Hoffman & Hoffman public relations," said AAAS spokeswoman Ginger Pinholster in an email to AFP.

"We immediately contacted a climate change expert, who confirmed that the information raised many questions in his mind, too. We swiftly removed the news release from our Web site and contacted the submitting organization."

Scientist Osvaldo Canziani, who was part of the 2007 Nobel Prize winning Intergovernmental Panel on Climate Change, was listed as the scientific advisor to the report.

The IPCC, whose figures were cited as the basis for the study's projections, and Al Gore jointly won the Nobel Prize for Peace in 2007 "for their efforts to build up and disseminate greater knowledge about man-made climate change," the prize committee said at the time.

Canziani's spokesman said Tuesday he was ill and was unavailable for interviews.

The study cited the UN group's figures for its projections, combined with "the business-as-usual path the world is currently following," said lead author Liliana Hisas of the Universal Ecological Fund (UEF), a non-profit group headquartered in Argentina.

But climate scientist Rey Weymann told AFP that the "study contains a significant error in that it confuses 'equilibrium' temperature rise with 'transient temperature rise.'"
