Imagine this dire scenario: the Atlantic Ocean’s sea currents which bring warm water to Europe collapses, making large swaths of the continent as cold as the Arctic Circle.In a grim turn, that’s just the scenario that a team of European scientists are warning about in a new study in the journal Nature Communications: that this catastrophic collapse — along with the ruination of the Amazon rainforest and the melting of polar ice — is on track to actually happen if we continue along our current path.
Specifically, the scientists say these major Earth systems, important for keeping the global climate stable for human civilization, face a 45 percent or greater chance of collapsing in the next 300 years, even if we temporarily bring back global warming below the 1.5 degrees Celsius threshold. Worse, the collapse may be irreversible.
The researchers modeled a range of climate policies on carbon emission rates, while inputting climate data on the Amazon rainforest, polar ice in Greenland and West Antarctica, and the Atlantic Meridional Overturning Circulation, which regulates the flow of warm water from the tropics to Europe.
“Domestic policies to reduce emissions need to be adopted and implemented, not only pledged, and a more significant and urgent effort is needed to mitigate the risks associated with tipping elements,” the scientists write.
