Public discourse has been polluted now for decades by corporate-funded disinformation - not just with climate change but with a host of health, environmental and societal threats. The implications for the planet are grim.

Bring down Mike Mann and we can bring down the IPCC, they reckoned. It is a classic technique for the deniers movement, I have discovered, and I don't mean only those who reject the idea of global warming but those who insist that smoking doesn't cause cancer or that industrial pollution isn't linked to acid rain.

I was interested in variations in temperatures of the oceans over the past millennium. But there are no records of these changes so I had to find proxy measures: coral growth, ice cores and tree rings.

Keith's [Briffa] series...differs in large part in exactly the opposite direction that Phil's [Jones] does from ours. This is the problem we all picked up on (everyone in the room at IPCC was in agreement that this was a problem and a potential distraction/detraction from the reasonably consensus viewpoint we'd like to show w/ the Jones et al and Mann et al series).

Although scientific revolutions in how we see the world do occur, the bulk of our scientific understanding comes from the cumulative impact of numerous incremental studies that together paint an increasingly coherent picture of how nature works.
