The rivers in the ocean mustn’t stop
The alteration of ocean dynamics in the North Atlantic Ocean is a factor that adds uncertainty to climate change forecasts. It raises alarm bells about a possible turning point in the water cycle with irreversible negative consequences and proves the close relationship between all factors that determine life on Earth.
In the current planetary situation, a weakening of the AMOC would have important climate and geological effects. In Europe, a further slowing of the Gulf Stream could cause more violent meteorological phenomena in winter and more intense summer droughts. In northern Africa, rainfall would tend to decrease and in the tropical and subtropical region of the Atlantic Ocean, the increase of water temperature and the subsequent increase of vapor in the atmosphere, factors which have already appeared, could increase the virulence of hurricanes and the extension of their season. On the other hand, the east coast of the US would be threatened by a drastic rise in sea level, as was the case in 2009 and 2010, when the Gulf Stream inexplicably weakened by 30% and the rise in sea level broke a 100-year record in tide gauge readings.
The study of the consequences of the alteration of sea currents shows the inevitable interrelationship of all parameters that govern life on Earth. Knowing the ocean means knowing the atmosphere, rivers, ice, forests. Nothing is isolated. In order to save any habitat, it is necessary to save all others.
