The good news is that so far climate models have all been dramatically wrong in their predictions of global mean temperature, and that all of them have erred on the high side. It's striking how little knowledge climate activists have of relevant evidence.

Hopefully the demise of our species will be quick and relatively painless, then.

It will be bloody and violent and probably the single largest amount of human suffering from a single event in the short history of our civilization.

While it is an oversimplified game, Fate of the World can help show how increasing temperatures puts more energy into global systems resulting in intense storms, droughts, flooding, wildfires, famines, etc, and how that destabilizes regions leading to less effective ability to implement anti-warming policy.

On the bright side, forecasters that rely on computer models of massive systems often end up making horribly inaccurate predictions. For example, we usually get tomorrow's weather wrong.

Being wrong goes both ways
