See how CO2 normally peaks at 280 ppm, throughout the Pleistocene or Holocene Epoch maxima?
See how CO2 suddenly moves up, in a geologic second, to really accelerate, 1950, all the way, to 400 ppm?
You know what ALWAYS HAPPENS, when CO2 goes up, really fast? Global temperatures follow, forced UP.
You know what happens, before temperatures get really HOT? First, temperatures ease upward, while ice melts and CO2 gets metabolized, by ocean water, which becomes relatively acidic. This keeps the atmospheric CO2 AND temperatures relatively low. Sea grasses start to proliferate.
But at some tipping point, the Arctic cap ice fails, which leaves the northern albedo ineffective, at reflecting energy, during northern summers. The planet will absorb a lot more energy, and that ice will all melt, every year. When we reach this point, the oceans will be killing oysters, corals, plankton, little fish, and eggs, with relative acidity, which is going on, NOW.
The Earth's oceans then start to warm. While they are out-gassing a lot of CO2 and CH4, already, this process accelerates, which will then accelerate both atmospheric GHG concentrations AND warming, of all global temperature measurements.
We will ALL be dead, by the time the oceans really start to warm up. Anoxic events will finish off whatever desirable species and families weren't killed off, by acidification. Rather than pass relatively acidic, cold water, the oceans will become caustic, in some places, but they won't respirate CO2, as well, without algae blooms and sea grasses.
Any surviving humans who want seafood will have to process jellyfish, into sushi.
Then the heavy tides will trigger seismic events and volcanism. Enjoy your jelly-sushi, kids!
