We can simplify the huge challenge of solving climate change into three steps:
1. Stop adding excess carbon dioxide and other greenhouse gases to the atmosphere. This requires transitioning from fossil fuels to sustainable energy.
2. Protect the remaining natural systems and start regrowing as many as we can to increase our planet’s natural carbon-carrying capacity.
3. Mop up the excess, ancient carbon dioxide until atmospheric carbon dioxide levels have returned to pre-industrial levels.
