The 38-year-old statistician, author of the controversial book "The Skeptical Environmentalist," enraged the scientific community by saying that the dangers of global warming had been exaggerated and that trying to slow it was a waste of money.

"The panel must conclude that none of the reports represent scientific work or methods in the traditional scientific sense," the five scientists said in their report.

In his book, Lomborg said the world's forests are barely declining, few animals have become extinct lately and rivers and oceans are becoming cleaner.

Lomborg has also criticized the vast sums being spent on reducing pollution, arguing that the amount spent on reducing greenhouse gas emissions would be enough to provide every person in the world with access to clean water and sewerage.
