Guest post by Maurizio Morabito
Quite an effort has been made by many people (including Dr Richard Muller) to portray the BEST pre-pre-pre-papers as some kind of death blow against climate skepticism, as if the whole debate had been a sports match with everybody pigeonholed in two opposite camps: here, the noble scientists finding out the world is warming; there, the ignoble skeptics pretending the world is not warming.
Needless to say, it’s all the usual crass, outdated lie.
How do I know? I know it from the About page at [my] blog. Why? Because that page does not contain just a text by Yours Truly, rather a large quote by Willis Eschenbach. [Who is a major essay contributor here at WUWT.]
It was simply such an appropriate, informed, short and straight argument, I knew it was going to describe pretty much all my future efforts at the blog.

I also think that increasing GHGs will warm the earth … but that is not the real question to me. The real question is, how much it will warm the earth. To date, I have not seen any “useful quantative results” regarding that question either …
Once those quantitative results are in, we can proceed to the next question — is a warmer earth better or worse on balance? The globe has warmed quite a bit since the 1600s, and in general this has been of benefit to humans. The sea level rise from the historical warming has not been a significant problem. In addition, a warmer world is predicted to be a wetter world, which overall can only be a good thing. So, will warming be a problem, or a benefit? This is a very open question, and one which will be difficult to answer as some areas will win and some will lose. To date, however, recent warming seems to be occuring outside the tropics, in the night-time, in the winter … this does not seem like a bad thing.
And at some future date when those questions are answered, we can proceed to the final question, viz:
If GHGs are determined to be a major cause of the warming (as opposed to landuse changes, or black carbon on snow, or dark colored aerosols, etc) and if we determine that the warming will be on balance a negative occurrence, is there a cost-effective way to reduce the GHGs, or are we better off putting our money into adaptation?
Until we can answer all of those questions, we should restrict ourselves to actions which will be of value whether or not there is future warming. The key is to realize that all of the problems that Al Gore is so shrill about are here now with us today — floods, heat waves, famine, rising sea levels, droughts, cold spells, and all of the apocalyptic catalog are occuring as I write this. Anything we can do to insulate the world’s population from these climate problems will be of use to everyone no matter what the future climate holds [...]
