What's going to happen? Likely nothing since there have been way higher levels of CO2 in the past.
So again, I find nothing to panic about.

You people can panic all you want, I find it highly entertaining.

Sure buddy...

Ocean acidification has been compared to anthropogenic climate change and called the "evil twin of global warming"[19][20][21][22][23] and "the other CO2 problem".[20][22][24]

Such a repeated carbon release is in line with current global warming.[2] A main difference is that during the Paleocene–Eocene Thermal Maximum, the planet was essentially ice-free.[4] However, the amount of released carbon, according to a recent study, suggest a modest 0.2 gigatonnes per year (at peaks 0.58 gigatonnes); humans today add about 10 gigatonnes per year.[5][6]

Rest assured, we only inject 50 times as much carbon as what caused the mass extinction 56 million years ago.
Highly entertaining. I wonder what else entertains you.
