‘Seismic Shift’ In Climate Science: UN IPCC CO2-Induced Warming Estimate ‘Far Too High’

The IPCC said they were over estimating the damaging effects of CO2 by double what it was.
That's why none of their dooms day CO2 centric climate predictions came true. So instead of linking them all here is the root cause.

Neil saidjust a few pages back the sun has nothing to do with the climate.

As I understand it,the IPCC will not publish a prediction unless there's a high degree of certainty to the magnitude and time frame.
Since we're in an untried experiment,we have no a priori knowledge about how things are actually going to go,there's no way any climatologist can actually pin hard numbers or time frames on scenarios.
That said,what some of the climatologists are observing is advancing so quickly,and geometrically,that they warn that we don't have the luxury to wait until we have 'certainty.' We'll be beyond the tipping points,and the disruption irreversible.
The IPCC has all the worse-case-scenarios in hand,but they can't factually say anything about them.
