Two Distinct Climate-Engineering Paths

  • Geoengineering splits into two main categories: carbon removal and sunlight reflection.
  • Carbon removal lowers long-term CO2; sunlight reflection reduces warming for a given CO2 level.

CO2 Is A Long-Term Bathtub Problem

  • CO2 accumulates and effectively traps warming on political timescales because it lasts thousands of years.
  • Cutting emissions stops further warming but doesn't undo past emissions; removal is needed to reduce existing CO2.

The Two Deep Objections

  • Two core objections to geoengineering are 'meddling with nature' and moral hazard.
  • Moral hazard worries that band-aid fixes might reduce emissions-cutting incentives, though Keith disputes that conclusion.
