Lack of warming in the Southern Ocean (yellow band across the bottom of Fig. 5) is an indicator of the approach of a Point of No Return: the collapse of the West Antarctic Ice Sheet (WAIS). 15/20

“Global Warming in the Pipeline” paper showing accelerated global warming was greeted by some scientists with a large public following (e.g., Michael Mann) with denial. 5/20

@nephologue Actually, renewables (except for the FF energy used to create/install them) are climate neutral but FF are climate negative. Building RE doesn't help climate but getting rid of FF does. Our policies should phase out FF rather than promote RE.

Much of the acceleration in warming occurred over the North Pacific & North Atlantic where ship aerosols decreased due to new International Maritime Organization (IMO) fuel regulations. 9/20

@WeatherProf And already, Extremely Hot Summers (>3-sigma the 1951-1980 mean) happen 200X (20,000%) more often that 50 years ago. Not a prediction & not based on models. Already happened & based on thermometer readings.

"Extremely Hot Summers" Now Happen 200X More Often Than 50 Years Ago [Updated]

James Hansen has updated his “Bell Curve” paper to include the last decade (2009-2019). To me, these bell curves — that show the distribution of average summer (July to August) temperatures — are...

Aerosols are key to understanding global warming but they remain unmeasured & are usually inferred by climate models in order to make the models match observations. 10/20

@davelevitan Climate scientists are conservative in the opposite way that risk managers (eg, in an insurance company) are conservative.

Hansen derides lack of progress on nuclear power in past decades & takes a swipe at Amory Lovins who convinced Bill Clinton that nuclear wasn’t necessary since he said wind, solar and energy efficiency were all that was needed. 17/20

@blkahn When averages go up a little bit, extremes can go up a lot. Extremely Hot Summers now happen 200X more often than 50 years ago.

Data shows that increased forcing (warming) from IMO ship rules is ~10X more than IPCC models show: at least 0.7W/m^2 vs. 0.079 W/m^2 for the IPCC. 12/20

Note that other climate scientists (Mann, etc.) say the model used in this paper is too simple & more complex models do not show the permafrost runaway feedback effect. I am not saying the paper is correct but we have enough info now to pursue Climate Restoration urgently.
