The Real Global Warming Disaster by Christopher Booker | Book review | Books | The Observer:
"Suppose you are genuinely undecided on climate change and determined not to be guided simply by what you'd like to believe. If unpicking the real story demands so much effort and insider knowledge, how can you possibly make up your mind? Here's an unscientific suggestion. 

Booker's position would require that you accept something like the following: 1) Most of the world's climate scientists, for reasons unspecified, decided to create a myth about human-induced global warming and have managed to twist endless measurements and computer models to fit their case, without the rest of the scientific community noticing. George W Bush and certain oil companies have, however, seen through the deception. 2) Most of the world's climate scientists are incompetent and have grossly misinterpreted their data and models, yet their faulty conclusions are not, as you might imagine, a random chaos of assertions, but all point in the same direction. 

There's a third option: the world's climate system is hugely complex, hard to predict and constantly surprising; yet in the long term the world is getting warmer, for reasons we basically understand, and there is good reason to believe that humans are mostly responsible for it."
