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-.)
