Global warming must peak below 2°C then return under 1.5°C as quickly as possible to limit the risk of dangerous “tipping points”, experts say.
Global warming must peak below 2°C then return under 1.5°C as quickly as possible to limit the risk of dangerous “tipping points”, experts say.
The new paper, by an international team of researchers, reviews the latest evidence and says global temperatures must cool to around 1°C above pre-industrial levels in the long term.
A tipping point defines when a small change in environmental conditions can spark a transformation that can be rapid and is often irreversible.
