Wie schlimm steht es wirklich um diese Erde???

Man weiß es nicht ganz genau. Aber man weiß, dass das Risiko sehr hoch ist, dass etliche Prozesse nicht mehr umkehrbar sein werden, und dass wir sehr nah an diesen Kipppunkten sind.

Nature: Climate tipping points — too risky to bet against
The growing threat of abrupt and irreversible climate changes must compel political and economic action on emissions.

"In our view, the consideration of tipping points helps to define that we are in a climate emergency and strengthens this year’s chorus of calls for urgent climate action — from schoolchildren to scientists, cities and countries.

The Intergovernmental Panel on Climate Change (IPCC) introduced the idea of tipping points two decades ago. At that time, these ‘large-scale discontinuities’ in the climate system were considered likely only if global warming exceeded 5 °C above pre-industrial levels. Information summarized in the two most recent IPCC Special Reports (published in 2018 and in September this year)2,3 suggests that tipping points could be exceeded even between 1 and 2 °C of warming (see ‘Too close for comfort’).

If current national pledges to reduce greenhouse-gas emissions are implemented — and that’s a big ‘if’ — they are likely to result in at least 3 °C of global warming. This is despite the goal of the 2015 Paris agreement to limit warming to well below 2 °C."
