    The carbon sequestered in the earth in the form of coal, oil and gas hasn’t always been in the earth. After all, hydro carbons are in fact hundreds of millions of years of dead trees buried under mud sequestering atmospheric CO2. Which implies there was a time with all that CO2 in the air yet still trees to capture it. By releasing it all, we reset the biosphere’s clock to about a time when earth supported a different kind of life (one without us in it), but life nonetheless.

    Frankly, the comparisons to Mars and Venus seem a bit overblown.

      Maybe, maybe not. We’re dealing with extremes that are accelerated here that have never been seen before in earths history, except when the dinosaurs went extinct, and I think 4 other very sudden climate changing events. But this one being human driven is unique, bcz all other events were naturally occurring (except the meteor impact of course). Species don’t have time to adapt to sudden changes in climate like this. We are very likely killing all life on earth right now, and it’s possible it will never recover.
