Iceland has classified the potential collapse of the Atlantic Ocean’s main current system, known as the Atlantic Meridional Overturning Circulation (AMOC), as a national security threat due to imminent climate change risks. This designation marks the first time Iceland has labeled climate impacts as an existential risk, prompting a coordinated governmental response.
Recent scientific research warns that the AMOC could destabilize, which would have profound implications for Iceland’s climate and economy. Environment Minister Johan Perl Johansson stated that the stability of ocean currents greatly affects climate, infrastructure, and the fishing industry.
The AMOC, essential for regulating weather in the Atlantic, is showing signs of slowing down due to rising temperatures and changing salinity. Experts like oceanographer Stefan Rahmstorf argue that the risk of collapse is no longer remote, with potential consequences including rising sea levels, disrupted monsoons, and extreme cold spells in Europe.
In response, Iceland plans to initiate cross-government efforts to assess and mitigate the threat, highlighting the urgency of this issue for national survival and security.
