The Author of Heaven of Earth, Geologist Iam Plimer sums it up nicely.
Many scientists, he said, had not considered the history of the earth when discussing climate change, or factors including the earth's rotation, changing tides and solar winds.
"When you look at the selective evidence, then there's a chance that you might be frightened about the end of the world," Professor Plimer said.
"When you look at the comprehensive evidence, it just says the planet changes all the time."
Of course, all the doomsayers reckon that Plimer has used selective evidence to back up his claims.
His book has proved to be so popular 10,000 copies sold out in two days. That shows people do want to hear all sides of the debate and are prepared to spend money to buy a book to read about it.
