“Negative emissions” (from ATTP)

Key quote-within-a-quote from article at … And Then There’s Physics:

If the expected negative emissions cannot ultimately be achieved, the decades in which society had allowed itself a slower, softer transition would turn out to be a dangerous delay of much-needed rapid emission reductions. Saddled with a fossil fuel-dependent energy infrastructure, society would face a much more abrupt and disruptive transition than the one it had sought to avoid. Having exceeded its available carbon budget, and unable to compensate with negative emissions, it could also face more severe climate change impacts than it had prepared for.
