It's still only guesswork
And now we have another guess.
From what I've read about CC in general, people take some data, guess what that meant, guess again about what caused it, guess whether the same thing will happen in the future, guess whether mankind did/could/will (or not) have any input into the circumstances and then finally extrapolate those guesses into what should (or not) be done.
Now, I do believe that the UK is, on the whole, seeing some more extreme weather than we're used to. And I am receptive to the idea that this is caused by more energy in the atmosphere and oceans. However, since nobody seems to have a model of the atmosphere and oceans that can estimate next week's weather to any degree of accuracy better than a coin-toss, I am not willing to believe that they can translate their guesses about what it all means into any solid, actionable and reliable plan - or tell us if one's needed.
<This is the point where "climate" people pile in and say that their science is not meteorology. Which is a bit like saying biology is not chemistry. They deal with the same basic elements, but at different levels. However to understand the former you *do* need to have a pretty clear understanding of how the latter works and the basic laws it obeys.>
