Exceeding 1.5°C global warming could trigger multiple climate tipping points

https://www.un.org/en/climatechange/science/climate-issues/d... > "Exceeding 1.5°C could also trigger multiple climate tipping points — such as breakdowns of major ocean circulation systems, abrupt thawing of boreal permafrost, and collapse of tropical coral reef systems — with abrupt, irreversible, and dangerous impacts for humanity" It helpfully comes with a citation of a paper in Science which has the exact same title, "Exceeding 1.5°C global warming could trigger multiple climate tipping points": https://www.science.org/doi/10.1126/science.abn7950 > "Six CTPs become likely (with a further four possible) within the Paris Agreement range of 1.5 to <2°C warming, including collapse of the Greenland and West Antarctic ice sheets, die-off of low-latitude coral reefs, and widespread abrupt permafrost thaw."

An assessment of climate tipping points that are likely to be triggered at 1.5C degrees of warming: https://www.science.org/doi/10.1126/science.abn7950 The main threats would be near-term coral reef die-offs and ice sheet collapses.

From the article: > The six tipping points "likely" to be crossed, according to the research, published in Science, are: - Greenland Ice Sheet collapse - West Antarctic Ice Sheet collapse - Collapse of ocean circulation in the polar region of the North Atlantic - Coral reef die off in the low latitudes - Sudden thawing of permafrost in the Northern regions - Abrupt sea ice loss in the Barents Sea.
