According to a risk study, ice sheets and ocean currents at danger of climatic tipping points might destabilize each other as the planet warms, resulting in a domino cycle with devastating repercussions for humankind.

"The analysis implies that there is still a serious danger of activating cascading climatic tipping points below 2°C of global warming - i.e., in the Paris accord goal range," said Lenton. "What the new study doesn't do is break down the timeframe during which tipping point shifts and cascades might occur; instead, it concentrates on the end results. Thus, the findings should be seen as "commitments" that we may soon make to possibly permanent alterations and cascades, leaving a bleak legacy for future generations."

According to Prof. Anders Levermann, who is also at PIK but was not involved in the current research, the likelihood of a cascade of tipping points leads to a runaway greenhouse effect. As a result, the globe becomes increasingly hotter even if humankind stops emitting carbon, which is highly improbable. Instead, he stated, "The Earth will be as heated as humans make it, which means we're the ones who have to stop it."
