climate crisis - comparison - planetary tipping points - Hansen vs Rockstrom - Hansen makes a valid point. What Rockstrom might consider irreversible, although he doesn't explicitly say, but implies, Hansen speaks instead in more precise terms - The perspectives may be dependent on the knowledge that informs each scientist - Hansen's research into the unknown area of climate change, aeresols and cloud cover, is not considered in conventional knowledge that IPCC bases its conclusions on since it is unknown - Hansen's research uncovers that aeresols play a very large role, to such an extent that humans may be able to mitigate exceeding dangerous temperature thresholds pragmatically through aeresol interventions that impact cloud behavior -

planetary emergency - risk analysis - risk = probability x impact - If impact is high, then even low probability x high impact means high risk - If AMOC or Greenland icesheet melts, the impact is so high that it is not even economically measurable

• comment
  • if we have to wait until planetary tipping points are triggered, it will be too late. There has to be some other less catastrophic event that happens before that. Perhaps some combination of extreme weather events
  • We need to trigger sufficiently large social tipping points before planetary tipping points are breached.

• summary

  • good q uick opening paragraphs that summarize the plethora of extreme events in 2023 up to Sept 2023 (but misses the Canadian Wildfires) and also the list of potential planetary tipping points that are giving indication of being at the threshold.
  • He makes a good point about the conservative nature of science that underestimates impacts due to the inertia of scientific study.
  • Coins a good meme
    • Everything, everywhere, all at once
  • He ties all the various crisis together to show the many components of the wicked problem we face
  • finally what it comes down to is that we cannot stop the coming unprecedented changes but we can and must slow it down as much as possible and we should be prepared for a wild ride

• comment

  • It would be a good educational tool for deep and transformative climate education to map all these elements of the polycrisis and show their feedbacks and interactions, especially how it relates to socio-economic impacts to motivate transformative change and mobilize the urgency now required.

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

• for tipping point, planetary tipping point
• likely temperature thresholds for breaching planetary tipping points at 1.5 Deg C
  • Greenland Ice sheet
  • West Antarctica ice sheet
  • tropical coral reef system
  • boreal permafrost

!- slogan : from climate change to system change

Unfortunately, our fates are collectively tied so we must collectively do this at scale to prevent tipping points. The motto of the Tipping Point Festival: Reach Social tipping points before planetary ones are breached.
