There is no doubt that we need to get to a net zero CO2 emissions world at some point. It can’t be a surprise that this will take a very long time and unfortunately we do not have the technology to do it now and feed everyone on the planet.
Since any reasonable person will accept that we need to feed everyone on the planet, we need to get to a technological level where it will be possible while having net zero CO2 emissions.
And then we need to get to negative “emissions”.
Because the global temperature rise will only stabilise if we don’t take some the CO2 back, not fall back to pre-industrial temperatures.
