New IPCC report shows climate scientists struggling with failed predictions:
1. Catastrophic outcomes (e.g., ice sheet collapse) deemphasized.
2. But ramped up hysteria over slight (1.5C-2C) warming.

Translation from climate bedwetting-ese of the key points of the new IPPC report:
1. Natural variability drives climate.
2. Never mind those wild temperature model projections.
3. Forget about catastrophic events. 2/
Failed climate predictions force IPCC to dial back hysteria in new report. For example:
1987 - James Hansen predicts global temp 3-4C higher by 2020
2020 - Global Temps only 0.44C higher.

Climate hysterics can't even predict atmospheric CO2 levels (let alone the effects):
1978: CO2 levels to double by 2020
2020: CO2 level up by only 23%

The new IPCC report doubles down on hysteria over exceeding its temp targets of 1.5C and 2C. ipcc.ch/report/ar6/wg1…
But those targets are NOT science-based.
Climategate revealed they were 'plucked out of thin air.'

Just made-up hysteria. 5/
The new IPCC report backs off catastrophic climate claims because of prediction failures like at Mt. Kilimanjaro:
2008: Mt. Kilimanjaro snow to vanish by 2020
2020: Only thing melted is the prediction.

Here's another classic climate alarmist blunder:
1986: EPA predicts 2 feet of sea level rise for Florida by 2020.
2020: Sea level rise + subsidence in South Florida since 1986 has been < 4 inches.

New IPCC report forced to admit nature still in charge of climate. ipcc.ch/report/ar6/wg1…
Not surprisingly this summer's extreme weather disasters -- heatwaves, drought, floods -- have all happened before and will again! realclearenergy.org/articles/2021/…

Because extreme predictions have obviously failed, the new IPCC report is trying to make a mountain out of a molehill (i.e., exceeding the 1.5C target).
But satellites show average temp is warming at a modest rate of 0.14C per decade. drroyspencer.com/2021/08/uah-gl…
No big deal! 9/
In 2000, @Greenpeace used an IPCC report to predict that emissions would wreck Tuvalu's economy by 2020.
Instead, Tuvala was experiencing a pre-COVID economic boom.

Who can forget 'federal scientists' predicting that the Arctic would be ice-free by 2020?
Today Arctic ice ranges 6 million square kilometers. nsidc.org/arcticseaicene…

As the IPCC melts down anew re a predicted 1.5C increase, here's what didn't melt as predicted:
2009: Glaciers at Glacier National Park gone by 2020.
2020: Gone are Park signs claiming the glaciers would be gone.

IPCC says humans have (slightly) warmed the climate.
No doubt.
But the IPCC pretends warming is all emissions vs. urban heat island, land use and temperature manipulation.
Adjusting for urban heat island effect, warming disappears, per Roy Spencer. drroyspencer.com/2021/01/could-… 13/
Despite double-talk, new IPCC report admits changes are NOT unprecedented over hundreds to thousands of years. ipcc.ch/report/ar6/wg1…
We've always said, for example, the Medieval Optimum was as warm, if not warmer than today.
Here's a graph from the 1990 IPCC report. 14/
The new IPCC report fails to recognize slight warming & more CO2 have been great for humans & wildlife. ipcc.ch/report/ar6/wg1…
If not: Why are there so many of us? What is the planet so green? What are we growing more food than ever?
And the weather hasn't changed. 15/
The WaPo evaluates past IPCC claims:
"The scientists were right."
Sorry. Cimate scientists have never been correct.
