Individually, the climate computer game predictions (projections, simulations, BS -- you pick the right word) are all over the place.
The Russian INM model has been the most accurate. That could be by chance, since there are dozens of models, with dozens of different predictions,
I suspect the Russian model, in a very complex way, looks at actual global average temperature measurements since the 1970s, and predicts "more of the same".
No one knows exactly what CO2 does to the temperature in the troposphere, and no one knows what the climate will be like in 100 years.
But we have ALL lived with global warming since the 1970s.
So ... it makes no sense to believe wild guess predictions of future global warming, claimed to be COMPLETELY DIFFERENT than than the global warming we have enjoyed for the past 45 years.
Modern climate science takes a lot of "I don't knows" and spins them into a fairy tale of a coming climate crisis.
I'm not a believer in fairy tales, especially one I have been hearing since the 1960s.
The climate 'boogeyman' is always claimed to be coming in ten years ... and I believe it will ALWAYS be coming in 10 years ... because it is fiction.
