The right amount is the amount that drives net emissions to zero.
- JumpCrisscross 1y ago> right amount is the amount that drives net emissions to zero On what timeframe? Put it too soon and you risk social upheaval crashing the whole project. Put it too late and you cause unnecessary damage to the climate.
- djrj477dhsnv 1y agoThat's debatable. I haven't looked at the numbers, but surely there's some amount of net co2 emissions that doesn't have a significant impact on the climate.
- pfdietz 1y agoThe current global CO2 emission rate is about 200x the average emission rate during the Permian/Triassic mass extinction. Just slowing down these emissions buys time, which is useful and valuable, but is not itself a solution. Net CO2 emissions have to be driven effectively to zero or we're just delaying disaster. Also, "net emissions" that include CO2 being absorbed into the oceans must take into account that oceanic absorption declines as surface waters become more saturated with dissolved CO2 and the pH declines. The rate of carbon flux to the deep ocean (from descending organic detritus) is just a few percent of annual emissions.
