This piece looks at the logarithmic relationship between the concentration of CO2 in the atmosphere and temperature. This is something that is often (deliberately) overlooked by organisations like the IPCC and governments.

That log relationship has been well-known for a long time and is inherent in the IPCC and virtually all the literature. The blog makes some claims without backing. But putting aside the question of warming, studies show our IQ in critical thinking tasks goes down significantly at levels of 1000+ ppm. Modern humans and likely the most advanced civilization ever on Earth arose with CO2 levels below 300 ppm. We are now at 400. [we also shouldn't forget about the permafrost methane or that we continue to release increasing amounts of CO2 each year.]

It is generally accepted that CO2 concentrations below 5000ppm are safe. It is almost impossible to envisage levels getting anywhere near that. We can afford to relax and enjoy the abundant fossil fuels until a new technology for our energy replaces it. What we are doing now is going backwards.
