Examples of such \u2018negative\u2019 tipping points include the dieback of the Amazon rainforest, the melting of the Greenland icesheet, and the collapse of the Atlantic Meridional Overturning Circulation (AMOC). But not all tipping points are bad. In the interview, Anna and Tim also discuss how the triggering of \u2018positive tipping points\u2019 within human societies could lead to rapid decarbonization.   For further reading, please see: Tim Lenton\u2019s book \u2018Positive Tipping Points: How to Fix the Climate Crisis\u2019.
