Maurice Newman is chairman of the Prime Minister's Business Advisory Council. He must have thought that December 31 was April Fool's Day when he wrote an opinion piece in The Australian headed "Crowds go cold on climate cost".

He once again revealed his opinions on climate change science when he wrote "the scientific delusion, the religion behind the climate crusade, is crumbling" and "Australia, too, has become hostage to climate change madness".

His piece is a mix of common climate change myths, misinformation and ideology. While Mr Newman is welcome to his opinions, his writing reveals his sad misunderstanding of the facts about climate change.
