4 ways governments can create positive tipping points, according to this climate scientist

The world is approaching several critical climate tipping points. "A tipping point is where a small change makes a big difference to a system, thanks to amplifying feedbacks within the system that turn that little change into a big outcome," says Tim Lenton. But by engineering positive climate tipping points, Lenton argues we can accelerate the energy transition and pull the planet back from the brink.
