'Who's On First?'
During the depression , when human CO2 production declined 30%, CO2 continued its languid rise, with temperatures continuing to rise till 1941 when they began a slight decline to 1972, again with no change in CO2 rise despite WWII and post-war reconstruction.
The “Oncoming Ice Age!” scares in the early 70s was bogus. Yet another false alarm.
CO2 change has never preceded any temperature reversal for the last 550 million years.
Humans produce less than 5% of the annual contribution to CO2 in the atmosphere.
The world has spent 250 million years within two degrees of 22C – that’s 72F average vs the current 59F (15C). The dinosaurs basked at 18C, in a wet swampy world.
There has never been a 'tipping point' in the last 550 million years: not at the P-T extinction warming (to at least 28°C), nor, more surprisingly, at the “snowball earth” events when glaciers reached almost to the equator and albedo increased dramatically.
The exponential decline in the GHG effect of CO2 has been known since Arrhenius, and the numbers are now correct. The next doubling of CO2 to 800 ppm will increase its GHG effect by less than 2%, in theory.
So there is no justification to propose that CO2 a is in control of climate change,
