(998 posts)The earth will continue to exist .... with or without us.

(5,939 posts)All bets are off. We have no idea what this much CO2, this fast, will do.

(19,257 posts)Also caused by massive carbon outgassing. In 75,000 yr, CO2 levels rose from 400ppm to 3000ppm, we now believe.
The world didn't end. BUT.....90% of all life went extinct. I doubt we could ever reach 3000ppm CO2 now, with so much carbon locked away in geological formations, but 1000ppm by 2150 isn't out of the question, especially if the permafrost and subsea/sub-tundra methane deposits there thaw. And we're releasing it in under 500 yr, not tens of thousands of years.
Interesting times are ahead of us, I fear.

(5,939 posts)we could do in 200 years what took 75,000 years. That has not happened ever on this planet.
People tell themselves that life will go on on planet earth without us to give themselves an out mentally. We should be acting as if the very existence of all life on this planet is at risk.

(19,257 posts)The deep biosphere stretching a mile underground likely has more biomass than all the life here on the surface, and it is totally independent of surface conditions. The oceans could boil off and it would still be active.
It's just that it's primarily bacterial life, with the occasional nematode thrown in. Not very comforting, I know.
Think. Again.
(8,337 posts)...get these graphs out in front of the public, every day, updated continuously?
Uncle Joe
(58,389 posts)corporate media, temperature graphs are inflation and the diminishing Antarctic sea ice are stock prices, they will be on it 24/7.
They might even put it on milk cartons, "where's the sea ice?"
