The 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.
