Worst-case global warming scenarios not credible, says study

And neither are the best-case ones:

“Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter.“

So, basically, they argue that we can make the error bars smaller, from “1.5C to 4.5C” to “2.2C to 3.4C”

“Best-case global warming scenarios not credible, says study” is another way to spin this.

It will not be long before we learn the worst scenarios are actually too optimistic.
