Au milieu d’un Atlantique qui se réchauffe comme le reste de la planète, une zone fait exception. Au sud-est du Groenland, une tache d’eau anormalement froide persiste depuis plus d’un siècle, résistant obstinément à la tendance globale. Les scientifiques viennent d’en percer le secret, et les conclusions sont préoccupantes pour l’Europe.
During the Cold War, the US poured support into Arctic military outposts and climate research amid fears of a Russian invasion. Climate change is still on the military’s radar as a threat multiplier.
Some scientists fear the risk of a collapse to warm Atlantic currents has not been taken seriously.
Heat and cold are now established health risk factors, with several studies reporting important mortality effects in populations around the world.1, 2, 3 The associated health burden is expected to increase with climate change, especially under the most extreme scenarios of global warming.4, 5 However, robust estimates of excess mortality in the current and future periods are still challenging to obtain due to the numerous factors influencing vulnerability to heat and cold, including climatic, environmental, and socioeconomic conditions.6 These factors represent the main drivers of variation in mortality risks, which have been shown to differ geographically and across age groups.
