PARIS — Global warming exists and is unquestionably due to human activity, the French Academy of Science said in a report published Thursday and written by 120 scientists from France and abroad.
"Several independent indicators show an increase in global warming from 1975 to 2003. This increase is mainly due to the increase in the concentration of carbon dioxide," the academy said in conclusion to the report.
"The increase in carbon dioxide, and to a lesser degree other greenhouse gases, is unquestionably due to human activity," said the report, adopted unanimously by academy members.
The report contradicts France's former education minister Claude Allegre, a geochemist, who published a book called "The Climatic Deception" which claimed that carbon dioxide was not linked to climate change.
The report was commissioned in April by Minister for Research Valerie Pecresse in response to hundreds of environmental scientists who complained that Allegre in particular was disparaging their work.
