Jonathan Leake has a full-page article in the Sunday Times (paywalled). It's a pretty good summary of the state of play as we head to the IPCC Fifth Assessment Report next week although I don't think there's anything that will be news to readers here.
What seems clear is that whatever our response to climate change, whether it is geoengineering or replacing fossil-fueled electricity generation with low-carbon power stations and wind farms, the bills are likely to be astronomical. As long as public confidence in climate science is falling, it would be a brave political leader to sanction spending on that scale.
