Positive 'tipping points' could help us mitigate climate change

Over the last few years, the planet has blown past or come dangerously near to climate tipping points—irreversible levels of damage that then also create even more warming. But just as there are moments of no return that tip us over into climate disaster, the inverse exists as well. On the path to climate recovery, there are benchmarks that could set off a cascading series of technological advancements that would rapidly cut our carbon emissions.
