A study published Monday concluded that melting ice in Greenland caused by climate change could cause the Atlantic Meridional Overturning Circulation (AMOC) to collapse as soon as 2025, ushering in dramatic consequences for the planet. The new study raises a legitimate alarm that we may pass a key climate change tipping point sooner than previously thought, there’s a lot we still don’t know about exactly when it might happen. In recent years, studies have shown that the current is at its weakest in 1,000 years. Although scientists are not certain why, several studies have attributed that weakening to an influx of fresh water from the melting of Arctic sea ice, including the Greenland ice sheet, and increasing precipitation — both of which are results of global warming. Projecting forward from the gradual weakening of the system, they estimated the AMOC will collapse between 2025 and 2095, with the most likely date being around midcentury.
