As of 2021 tipping points are considered to have significant probability at today's warming level of just over 1 °C (1.8 °F), with high probability above 2 °C (3.6 °F) of global warming. [5] Some tipping points may be close to being crossed or have already been crossed, like those of the ice sheets in West Antarctic and Greenland, warm ...

There is already moderate risk of global tipping points at 1 °C (1.8 °F) above pre-industrial temperatures. That becomes a high risk at 2.5 °C (4.5 °F). [146]: 254, 258 It is possible that some tipping points are close or have already been crossed. Examples are the West Antarctic and Greenland ice sheets, the Amazon rainforest, and warm ...
In 2022, a major review of tipping points concluded an AMOC collapse would lower global temperatures by around 0.5 °C (0.90 °F) while regional temperatures in Europe would fall by between 4 °C (7.2 °F) and 10 °C (18 °F). [14] [100] A 2020 study assessed the effects of an AMOC collapse on farming and food production in Great Britain. [162]
A new study in the journal Science finds that even the most aggressive goals of reducing greenhouse gas emissions aren’t sufficient to avoid several major climate change tipping points, in which ...
The tipping points include groundwater depletion, rising insurance costs, extreme heat, species extinction, melting glaciers and space debris. U.N. report warns of catastrophic climate tipping points.

The report on so-called “tipping points” — moments when the Earth has warmed so much that certain side effects become irreversible — looks at 26 different systems and points to five of ...
