So their positive tipping point example is using renewables. Next they will tell us that we need to use public transportation more, use bikes for our commutes and fly less! Wow!

This is the same message, slightly repackaged because our collective situation has worsened too much. I need these people to go in front of a microphone and say “The only way out is to abolish capitalism because that is what’s killing all of us”. Until then, this is all just substance-free.

Scientists have identified both negative and positive “tipping points” that could determine Earth’s fate. While negative tipping points include critical ecological thresholds like ocean acidification and biosphere integrity that threaten planetary stability, researchers at the University of Exeter are now mapping positive tipping points that could help combat climate change^[1].

These positive cascading effects are already emerging - the widespread adoption of wind and solar energy has driven down renewable costs while increasing clean energy generation^[1:1]. However, the global economy is still “decarbonizing at least five times too slowly to meet the Paris Agreement target of limiting global warming to well below two degrees Celsius,” warns Tim Lenton from the University of Exeter^[1:2].

The researchers aim to identify potential positive tipping points, understand how close we are to achieving them, and determine what actions could trigger them - while avoiding “wishful thinking about their existence”^[1:3]. Some sectors, like nuclear power and concrete production, may not have tipping points at all. But in others, like heat pump adoption and shifts away from meat consumption, positive cascading changes appear more likely^[1:4].
