Climate: Can we trust the IPCC on the big stuff?

About flaws in the Intergovernmental Panel on Climate Change report ...

We focus on three key topics: the impact of climate change on water supplies, food, and biodiversity. The investigation reveals that the IPCC's broad conclusions were sound. Indeed, the stringent rules of the IPCC means the report sometimes understated the potential impacts of climate change - on biodiversity, for instance.

But our findings suggest there may have been problems with the way its conclusions were presented. It was too easy for some numbers mentioned in passing in academic papers to find their way into public presentations of IPCC reports without sufficiently rigorous assessment.
