example - cascading tipping points via AMOC - As Arctic system melts faster, it releases more freshwater into the North Atlantic - This is happening on the southern tip of Greenland, for example and the lower density of water slows down the AMOC current - Warm saline water flows from the Southern Ocean up into the North Atlantic - When it reaches the southern tip of Greenland, the heat is radiated into the atmosphere and heats up Europe - When the freshwater meltwater from Greenland mixes with this AMOC current, the AMOC water is less heavy and sinks slower - This pushes monsoons further south, which can explain why there are more droughts and fires in the Amazon rainforest - The slowdown of the AMOC leaves more saline water stuck in Antarctica, potentially contributing to the faster melting of Antarctica glaciers

• for: system change - where to start

• paraphrase

  • You don't start a feminist revolution by arguing with your dad. He might be the one who needs to change, but that doesn't mean that you start there.
  • You start by talking to each other. We need to come together. We need to have solidarity.
  • We need to have a common narrative and analysis and understanding of what's happening.
  • And I think a common understanding of pathways of change and we need that core nucleus of people who really are working for system change.
  • I think that's where we start. And hopefully, the narrative and the clarity that we can bring will be compelling enough that we will win more hearts and minds

• for: cascading tipping points, cascading tipping points - Greenland - AMOC - Antarctica

• highlights

  • latest research at PIK shows that the two poles are connected via the AMOC current.
    • Greenland ice sheet melt releasing cold fresh water is slowing down the North Atlantic overturning of heat.
    • The slowdown is keeping more warm saline water in place in the Southern Ocean, accelerating melting of the Antarctic ice sheet.

• comment
  • graph that shows the unprecedented forest fires turning forests from carbon sink to carbon source

• for: interdependent, emptiness, cascading tipping points
  • the Arctic which is warming three times faster than the planet on average
  • and releases cold fresh water into the North Atlantic slowing down the whole overturning of heat in the North Atlantic
  • which pushes the monsoon further south
  • which can explain droughts and forest fires over the Brazilian part of the Amazon
  • moreover the slowing down of overturning of heat means that more warm water is stuck in the Southern Ocean
  • which can explain why the West Antarctic ice sheet is melting faster than we had expected so there's a connection between the North Pole and the South Pole in this web of interactive tipping elements so
• This is something we have to recognize we are today a big world on a very small planet and it's all interwired and we are interdependent now

!- cascading tipping points : example - melting Greenland glacier dumps cold fresh water into North Atlantic - excess cold water shows down the AMOC current - a slower AMOC causes monsoons to move further south - this causes drought and forest fires in Amazon rainforest and warms the southern oceans - warning southern oceans accelerates melting of Antarctica ice sheets

!- comment : slowing AMOC - can also affect many other processes - https://www.sciencefriday.com/segments/atlantic-ocean-currents-amoc/

to achieve large mobilization, a cascading social tipping point strategy can be fruitful, coupled with a conditional onboarding such as employed in the Simpol strategy: https://www.simpol.ph/ Conditional onboarding works because, like crowdfunding, nobody needs to make any resource commitment unless sufficient momentum is demonstrated.
