This is not an ordinary scientific mission; it is a watchman guard over the engine that keeps Europe’s climate alive, and its logistical operations center is located in Santa Cruz de Tenerife, which has discreetly hosted the RSS Discovery. As the research vessel ventures into the depths of the Atlantic, Tenerife’s ports are consolidating as the fundamental strategic base for the official UK expedition. From here, the National Oceanography Centre (NOC) in Southampton coordinates the deployment of cutting-edge technology to monitor the AMOC (Atlantic Meridional Overturning Circulation), the current that prevents winters in Madrid or London from being as frigid as those in Montreal. The operations at the Tenerife dock are the prelude to a daunting task at more than 3,000 meters deep. British scientists, led by Dr. Ben Moat, are utilizing Tenerife as a platform to prepare weighed cables and monitoring equipment that must remain submerged for two years. Precision is paramount: maneuvering an oceanic colossus to release instruments at the exact point requires logistics that only high-specialization ports, like those in the province of Tenerife, can guarantee for an international expedition of this magnitude. Aboard the RSS Discovery, the atmosphere is one of contained tension that Alex Thomson from the British network describes as ‘chills down the spine.’ Analyzing the data collected at the workstations, the trend is undeniable: since 2004, the lines on the graph measuring the strength of the AMOC current have been steadily declining. The weakening is constant, and the shadow of 2009 looms over the researchers; that year, a confluence of phenomena nearly halted the current, resulting in 2010 being the coldest December in a century in the UK and causing sea levels in New York to rise by 13 centimeters. The science emerging from this Tenerife-based expedition warns that the melting of Greenland, driven by fossil fuel burning, is flooding the North Atlantic with freshwater, sabotaging the global circulation system. Professor John Siddorn, director of the NOC, emphasizes the urgency of making decisions based on this physical data before the current’s retreat becomes permanent. Tenerife is not just dispatching ships; it is dispatching the last opportunity to understand whether the Atlantic engine is shutting down permanently before our eyes.
