Benchmarking on 2005, the past 25 years saw an approximate increase of 0.4 C over that interval. If warming continued at that rate, it would be a 1.6 C rise over century. And as atmospheric CO2 concentrations increase, the models predict an acceleration of warming, so I fail to see why 2.0 C over the course of the 21st century is outlandish. Wish I could be here in 2100 to see where it actually is; but if the predictions of this and other environmental issues are borne out, I don't think the world in 2100 looks particularly appealing. Sad news for my grandchildren.
If the models are off by a factor of two, then warming will hardly be a problem at all - the most temps will ever increase is 1.5C to 2.0C over centuries which is not likely to be a big problem. I hope you see my point.
You and Patrick Michaels enjoy a high level of agreement. For a long time, 2.0 C increase was considered a threshold level; significant effects are predicted to kick in with increases not much more than that. If the world managed to keep the warming at 2.0 C, that would be a reasonable outcome. Considering how successfully the world appears to be at managing any issue of international consequence, I'm not overly optimistic.
I see you are still around peddling your globull warming nonsense. It’s good to know that 31,000 scientists (and many other intelligent Americans) disagree with you.
