Iceland’s National Security Council formally labelled the possible collapse of the Atlantic Meridional Overturning Circulation (AMOC) a national security risk in September — the first time the country has applied such a designation to a climate impact.
The move followed a government briefing on new research that raised “grave concerns” about the system’s future stability.
Jóhann Páll Jóhannsson, Iceland’s minister for environment, energy and climate, said the risks extend far beyond weather.
