Going carbon-neutral might have been the right answer 20 years ago. To avoid 1.5 degrees of warming above pre-industrial levels, we need to go carbon-negative today. Even if we reach 0 in 13 years, the road to flipping the magnitude will be long, and I estimate longer than the time to build a reactor.
