Iceland Runs Crisis Exercise for AMOC Ocean Current Collapse

Iceland is running a crisis exercise to simulate the collapse of the Atlantic Meridional Overturning Circulation (AMOC) ocean current. This exercise is taking place now, in 2026, as the country prepares for potential climate-related disruptions. The AMOC plays a crucial role in regulating global temperatures, and its collapse could have severe consequences for coastal communities and ecosystems.

According to The Conversation, the risk of AMOC collapse is missing from almost all national climate plans, despite the potential for catastrophic consequences. The Conversation notes that key Atlantic currents could collapse this century, but this risk is not being adequately addressed. Gizmodo reports that Iceland's crisis exercise is a step towards preparing for this potential disaster.

The caveat is that the exact timing and likelihood of AMOC collapse are still uncertain. While the exercise is taking place now, it is not clear when or if the AMOC will actually collapse.
