The world's most high-profile climate change sceptic is to declare that global warming is ''undoubtedly one of the chief concerns facing the world today'' and ''a challenge humanity must confront'', in an apparent U-turn that will give a huge boost to the embattled environmental lobby.
Bjorn Lomborg, the self-styled ''sceptical environmentalist'' once compared to Adolf Hitler by the United Nations climate chief, is famous for attacking climate scientists, campaigners, the media and others for exaggerating global warming and its effects on humans, and the costly waste of policies to stop the problem.
But in a new book to be published this month, Lomborg will call for tens of billions of dollars a year to be invested in tackling climate change.
Looks like denialist can change. While this is a PR boost, it doesn't effect the science of global warming. He is an economists not climate scientist nor is he a scientists in any field related to the climate.
