Warum wird eigentlich immer vom Ziel oder Target gesprochen? Ist doch ein Ceiling oder eine Grenze, bis zu.. könnte man noch annehmbare Lösungen finden, dannach wirds gruselig.
In den Medien klingt es immer so nach;" 1,5 ? ja, das schaffen wir! Sogar 2,5 schaffen wir!"

That is a silly thing to say:
It implies that the disruption is yet to happen when the truth is that it has been happening for a while now. A reduction of fruit and nuts of about 3-5% that accounts for yearly excess human deaths of 427,000 in the US alone (Smith et al. 2022).
