The science of climate change is inexact. It is about uncertainty and probabilities. Based on the evidence, a criminal lawyer would not be able to prove that humans are responsible for potentially catastrophic climate change. But the evidence would certainly nail down a civil conviction.
If the vast bulk of evidence says climate change is real and that humans are almost certainly to blame, why is the science being dismissed as exaggerated, unreliable or even fraudulent by the climate change doubters?
Opinion polls show that public skepticism about man-made climate change has climbed in recent months as the stories questioning the legitimacy of the science migrate from the Internet's fringes to the mainstream media.
The University of East Anglia affair certainly did a lot of damage. The university's Climatic Research Unit failed to keep proper records about Chinese weather stations and probably deleted potentially embarrassing correspondence to get around the Freedom of Information Act, among other sins. As far as scandals go, it's genuine.
