You're missing the point
Nobody is arguing that there is warming. It's the AMOUNT and the CAUSE that's the major debate.
So this study PROVES NOTHING. And you are reporting on the early draft!
"About" 1c since 1950 is KNOWN. If we face another 0.5c over the next 50-100 years... SO WHAT!
It's not worth wrecking the world trying to fix a problem that will have such a relatively small effect. Because while some areas will face higher temperatures, new areas will have rain and cooling.
So just as "snow" is jumped on by climate skeptics, so is a "straw man argument" leapt upon by zealots ..... and the world keeps turning and so on and so forth.
