World on brink of five 'disastrous' climate tipping points, study finds
The climate crisis has driven the world to the brink of multiple “disastrous” tipping points, according to a major study.
It shows five dangerous tipping points may already have been passed due to the 1.1C of global heating caused by humanity to date.
These include the collapse of Greenland’s ice cap, eventually producing a huge sea level rise, the collapse of a key current in the north Atlantic, disrupting rain upon which billions of people depend for food, and an abrupt melting of carbon-rich permafrost.
At 1.5C of heating, the minimum rise now expected, four of the five tipping points move from being possible to likely, the analysis said. Also at 1.5C, an additional five tipping points become possible, including changes to vast northern forests and the loss of almost all mountain glaciers.
In total, the researchers found evidence for 16 tipping points, with the final six requiring global heating of at least 2C to be triggered, according to the scientists’ estimations. The tipping points would take effect on timescales varying from a few years to centuries.

so the results are a less severe scenario. Like deforestation, loss of ocean oxygen and shifting Indian Monsoon...
He added that much more research was needed to narrow down the critical temperature thresholds, with current estimates remaining highly uncertain.

unfortunately, these warnings continue to fall on deaf ears, as the 1% and oil companies double down on their own gains at the demise of the rest of the planet
