Unknown / Black Swan

The identification of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC) by Iceland as a security risk is a significant Black Swan signal. Such an event could drastically alter global climate patterns, leading to severe weather changes, disruptions in marine ecosystems, and impacts on global agriculture and economies. This development is particularly concerning because it represents a complex, interlinked system that is difficult to predict and manage, with potential for widespread and unforeseen consequences. While other geopolitical and technological risks are present, the potential AMOC collapse stands out due to its global scale and the profound environmental and socio-economic disruptions it could cause.
