Iceland declares the potential breakdown of a vital Atlantic Ocean current an existential and national security threat, marking an unprecedented move in climate policy.
COPENHAGEN, Nov 13: Iceland has officially classified the potential collapse of a key Atlantic Ocean current system as both a national security concern and an existential threat, marking the first time the country has treated a climate-related phenomenon with such seriousness.
The decision, announced by Climate Minister Johann Pall Johannsson, enables Iceland’s government to plan and coordinate for worst-case climate scenarios. The move follows growing scientific warnings about the Atlantic Meridional Overturning Circulation (AMOC) — a vast ocean current that carries warm tropical waters northward, helping to keep Europe’s climate relatively mild.
Scientists caution that rising global temperatures and accelerated melting of Greenland’s ice sheet are releasing massive amounts of cold freshwater into the North Atlantic. This influx could disrupt or even shut down the AMOC, potentially triggering a modern-day ice age across Northern Europe. Such an event could bring severe cold, heavier snowfall, and long-lasting winters to the region.
Johannsson told Reuters that this is the first time Iceland’s National Security Council has formally recognized a climate-related process as a potential existential threat. “It is a direct risk to our national resilience and security,” he said, emphasizing the importance of early preparedness.
In response, Icelandic ministries are now on alert and coordinating across sectors to assess potential impacts. The government is also drafting new disaster preparedness policies and exploring additional research to monitor ocean changes and strengthen national resilience.
