Research indicates that humanity’s 1.1°C of global heating might have already triggered five dangerous tipping points. These include the potential collapse of Greenland’s ice cap, leading to significant sea-level rise, disruption of a critical current in the North Atlantic affecting food-producing rain for billions, and abrupt thawing of carbon-rich permafrost.
Even with a minimum temperature rise of 1.5°C, four of these tipping points shift from possible to likely.
