really do intend to contain global warming to within 2 °C, there is no alternative to

He also seems to have missed the recent revelation that what
really matters to climate is the total ultimate slug of emitted CO2, implying that unfettered
emission today dooms us to more
drastic cuts in the future or a higher ultimate atmospheric CO2 concentration, which will persist not just for «possibly centuries», but almost certainly for millennia.
