Forty-four scientists from 15 countries are raising concerns about the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current that affects global climate. Their open letter highlights how global warming is weakening this vital system, which could lead to significant cooling in some regions and serious impacts worldwide.
Addressed to the Nordic Council of Ministers, this message comes from experts in various fields, including Dr. Didier Swingedouw from the French National Center for Scientific Research. They warn that the potential collapse of the AMOC may be closer than we think, suggesting that its risk has been “largely underestimated.” While the Intergovernmental Panel on Climate Change (IPCC) suggested a low chance of abrupt collapse before 2100, newer studies indicate this might occur within decades.
The AMOC moves warm water northward from the southern Atlantic. As it cools, the water sinks and helps redistribute heat and carbon globally. A key player in this process, the Gulf Stream, significantly affects weather patterns in Europe, America, and Africa. However, as temperatures rise, particularly in polar regions, the AMOC weakens. This disruption could lead to rising sea levels and chaotic weather patterns around the world.
If the AMOC were to collapse, the consequences could be dire. Scientists warn of severe cooling in northern areas and unpredictable weather events that could disrupt agriculture and ecosystems. For example, northern and western Europe might experience extreme shifts in temperature and rainfall. Meteorologists emphasize that atmospheric changes are connected, meaning this is not just a localized issue. One researcher reflected, “Adapting to such extreme conditions isn’t a feasible option.”
There’s a growing call for urgent action to limit global warming to below 1.5°C above pre-industrial levels. Recent data suggests we may already be approaching this limit. According to the World Meteorological Organization, Earth’s average temperature has already risen by about 1.2°C since the late 19th century, raising alarms among climatologists about the urgency of the situation.
In the face of these challenges, more attention is needed. As citizens and researchers alike grow more concerned, discussions on platforms like Twitter have surged, amplifying awareness of climate risks. The stakes are high, and immediate measures are crucial to safeguard the planet’s climate and ecosystems.
