Iceland is Planning For the Possibility That Its Climate Could Become Uninhabitable

Iceland Declares Ocean Current Collapse a National Security Risk Amid Dire Climate Warnings

In a historic and unprecedented move, Iceland has officially classified the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC) as a national security risk. This bold designation marks the first time a nation has formally acknowledged the existential threat posed by the possible breakdown of this critical ocean current system, which acts as Iceland’s natural central heating by transporting warm tropical waters northward.

The AMOC, often referred to as the “conveyor belt” of the Atlantic, plays a vital role in regulating global climate patterns. For Iceland, it is nothing short of a lifeline, ensuring milder winters and a habitable environment in an otherwise harsh Arctic region. However, recent scientific studies have painted a grim picture, suggesting that the AMOC is far more vulnerable to collapse than previously believed.

A groundbreaking study analyzing nine climate models under high-emission scenarios found that the AMOC weakened and collapsed in every single instance. Even under the more optimistic emission targets set by the Paris Agreement, researchers estimated a 25% chance of shutdown. Stefan Rahmstorf, an oceanographer at Germany’s Potsdam Institute for Climate Impact Research and a co-author of the study, emphasized the urgency of the situation, stating, “It is wrong to assume this was low probability.”

The implications of an AMOC collapse are staggering. Simulations of a post-collapse world project Icelandic winter temperatures plummeting to a bone-chilling minus 50 degrees Celsius, with sea ice encircling the island for the first time since Viking settlement over a millennium ago. Such conditions would render large parts of the country uninhabitable, displacing communities and devastating ecosystems.

Iceland’s proactive stance comes as part of its broader national strategy to address AMOC risks, which is set to be finalized by 2028. The country has also raised concerns about the future of climate research, particularly highlighting the recent targeting of NASA Goddard for significant staff and budget cuts under the current U.S. administration. NASA Goddard has been a key source of AMOC modeling and data, and any reduction in its capabilities could hinder global efforts to monitor and mitigate the risks associated with the current’s potential collapse.

This move by Iceland underscores the growing recognition among nations that climate change is not just an environmental issue but a profound threat to national security, economic stability, and human survival. As the world grapples with the escalating impacts of global warming, Iceland’s decision serves as a stark reminder of the urgent need for coordinated global action to address the climate crisis.
