Quote from drjekyllus:
And what exactly does that prove? Trees seem to love it.
Given that atmospheric CO2 has increased massively, they clearly aren't sufficiently absorbing the extra.
The CO2 that is stored in fossil fuels was once part of the atmosphere.
Yes, over millions of years, and it's all being released at once.
Saying that some of the CO2 in atmosphere was put there by burning fossil fuels is not significant. Why is there a bias against CO2?
It is significant. As you've just pointed out temperatures were much higher during periods of high CO2.
