The point of jumping up and running screaming has been passed.
Thank you Paul for calmly and precisely explaining the science.

Exploring the risks of ‘cascading’ tipping points in a warming world
Tipping elements within the Earth system are increasingly well understood.
Scientists have identified more than 25 parts of the Earth’s #climate system that are likely to have #TippingPoints – thresholds where a small additional change in global warming will cause them to irreversibly shift into a new state.
The “tipping” of these systems – which include the Atlantic Meridional Overturning Circulation (#AMOC), the #Amazon #rainforest and the #Greenland ice sheet – would have profound consequences for both the #biosphere and people.
More recent research suggests that triggering one tipping element could cause subsequent changes in other tipping elements, potentially leading to a #TippingCascade.
For example, a collapsed AMOC could lead to dieback of the Amazon rainforest and hasten the melt of the Greenland ice sheet.
However, the interactions between individual tipping elements – and the ways they might trigger each other – remain largely underexplored.
In a review study, published last year in Earth System Dynamics, we unpack the current state of scientific understanding of the interactions between individual tipping elements.
We find that scientific literature suggests the majority of interactions between tipping elements will lead to further destabilisation of the climate system.
Existing research also indicates that “tipping cascades” could occur even under current #GlobalWarming projections.
Scientific understanding of individual #TippingElements is continuously improving, but more research on their interactions is needed.
Scientists from
@PIK_climate ran models and found that the notorious "overshoot" scenarios can trigger irreversible #TippingCascade even if temperature drops back to 1.5C.

(But how wd we even survive as civilisation if *C first rose to 2C and then dropped back to 1.5 by 2100? The tech feasibility and impact chaos from 2C aside (collapse certain IMO) -
going back 0.5C in only ~50yrs leaves biosphere in an uproar, no? Migrated species lose niche -again-.)
12/22/2022 - Temporarily overshooting the climate targets of 1.5-2 degrees Celsius could increase the tipping risk of several Earth system elements by more than 70 percent compared to keeping global warming in line with the United Nations Paris Agreement range, a new risk analysis study by an international team of researchers shows. This tipping risk increases even if in the longer term the global temperature would stabilize within the Paris range. Avoiding an overshoot would hence limit the risks, the researchers conclude.
