The positive tipping points that can help us solve the climate crisis

When it comes to climate change, we often think of tipping points as having a huge negative effect. Be it the loss of ice sheets in the Arctic, the deforestation of the Amazon rain forest or the alteration of ocean currents, scientists have identified several key systems on the Earth that will be impossible to reverse if they cross a critical threshold. But if we look at the situation from the opposite side, there are also several positive tipping points that, given the correct momentum, can potentially halt the crisis the planet is facing.

In this episode, we’re joined by Prof Tim Lenton, chair in Climate Change and Earth System Science at the University of Exeter, to talk about his latest book Positive Tipping Points – How to Fix the Climate Crisis.

He tells us how the pop group A-ha helped Norway to lead the way in the adoption of electric vehicles, how government mandates can act as powerful amplifiers to get us closer to these vital climate tipping points, and how each positive tipping point can feed into another to push us closer to a greener future.
