"There is great urgency to moving rapidly off fossil fuels. It will not stop climate change in its tracks but it might just leave us with a liveable climate in the second half of the century."
Completely unfounded assertion.
Staring from a wrong premise, logical argument rapidly arrives at the wrong (but profitable)  conclusion.
Despite ever rising CO2 levels, the world is not warming appreciably at the moment. But almost certainly because of rising CO2 levels plants living on the edge of semi-arid areas are prospering. Less starved of CO2, they dont have to open their pores so much and lose less water as a result.
Burning coal is nearly as dirty a business as mining it. But it does not threaten the planet. Only the pocket books of those queuing up to sell  you overpriced subsidised unreliable intermittent 'renewable energy'.
Remember where renewable energy comes from. A huge unshielded nuclear reactor whose radiation kills ~700 people from skin cancer annually in South Africa.
