“Climate Scientists Warn of Devastating Collapse of Atlantic Ocean Currents: Urgent Action Needed Now”
Forty-four of the world’s leading climate scientists have issued a stark warning to Nordic policymakers regarding the potential collapse of key Atlantic Ocean currents. In an open letter published on October 21st, University of Pennsylvania climatologist Michael Mann and other prominent scientists highlighted the underestimated risks associated with the weakening of the Atlantic Meridional Overturning Circulation (AMOC).
The AMOC is a crucial ocean conveyor belt that includes the Gulf Stream and plays a vital role in transporting heat to the Northern Hemisphere. Recent research indicates that the AMOC is slowing down and could be approaching a tipping point due to the impacts of global warming, which could have catastrophic consequences for Earth’s climate.
The scientists emphasized that an AMOC collapse would have devastating and irreversible effects, particularly for Nordic countries such as Denmark, Iceland, Norway, Finland, and Sweden. The collapse of these ocean currents could lead to major cooling and extreme weather in the region, exacerbating the formation of a “cold blob” over the eastern North Atlantic. This disruption could also impact agriculture in Northwestern Europe and precipitate climate changes across the Northern Hemisphere.
Furthermore, the scientists warned that a halt in the AMOC could trigger a southward shift in tropical monsoon systems, leading to catastrophic consequences for agriculture and ecosystems globally. The collapse of these ocean currents could also result in higher sea levels along the American Atlantic coast and disrupt marine ecosystems and fisheries.
The scientists stressed the urgent need for climate action to prevent the potential collapse of the AMOC in the coming decades. While the latest report by the Intergovernmental Panel on Climate Change (IPCC) suggests a medium likelihood of the AMOC not collapsing before 2100, the scientists argue that this estimate is imprecise and insufficient given the catastrophic implications of such an event.
In their letter to the Nordic Council of Ministers, the scientists called for increased awareness of the risks associated with an AMOC collapse and urged policymakers to uphold the targets of the 2015 Paris Agreement to mitigate global temperature rise. They emphasized the need for international cooperation to address the imminent threat posed by the weakening of key Atlantic Ocean currents and minimize the risk of a climate catastrophe.
