A close look at the arctic sea ice models that have launched the careers of a thousand polar bears

This is Expertise the UN can bank on

In the GWPF 2018 Lecture, Richard Lindzen pointed out the genius of Arctic climate models

First, for something to be evidence, it must have been unambiguously predicted. (This is a necessary, but far from sufficient condition.) Figure 1 shows the IPCC model forecasts for the summer minimum in Arctic sea ice in the year 2100 relative to the period 1980–2000. As you can see, there is a model for any outcome.

It is a little like the formula for being an expert marksman: shoot first and declare whatever you hit to be the target.

This will definitely happen according to the worlds top scientists at NASA, CSIRO, Geophysical Fluid Dynamics Lab (NOAA), National Centre for Atmospheric Research, The Hadley Meteorological Centre, the Max Planck Institute for Meteorology – Germany, the Institute of Numerical Mathematics of the Russian Academy of Sciences, the University of Tokyo, JAMSTEC (Japan), the Climate Research Division of Environment Canada, The Bjerknes Centre for Climate Research in Norway, the Institut Pierre Simon Laplace (IPSL), plus experts from Centro Euro-Mediterraneo sui Cambiamenti Climatici; Istituto Nazionale di Geofisica e Vulcanologia (INGV).

Twenty one IPCC expert models can’t fail, unless of course, the world cools.
