Does global warming change ocean currents

Research topic: ocean currents

Influence of ocean currents on the climate

Oceans cover around 71 percent of the earth's surface. As a result of their enormous ability to store heat, they play a major role in the global redistribution of the energy absorbed by the sun. In this way, the oceans compensate for seasonal temperature fluctuations in the atmosphere. At the same time, they influence the earth's climate system for periods of several tens of thousands of years. The slow reaction of the climate to changes in greenhouse gas emissions is also largely due to the inertia of the oceans. More on the subject "

The warming of the earth leads to fundamental changes in important ocean currents. As scientists from the Alfred Wegener Institute show in a study, the wind-driven subtropical marginal currents in the northern and southern hemispheres will not only become stronger by the end of this century. The Kuroshio Current, the Agulhas Current and other ocean currents also shift their paths towards the Pole and bring more warmth and thus the risk of storms to the temperate latitudes.

Mild winters in Northern Europe, rains in West Africa, hurricanes in North America - with the energy that the great ocean currents distribute around the earth, they influence both the global climate and regional weather phenomena. One of the key regions for global ocean circulation is in the Labrador Sea between North America and Greenland. Researchers at GEOMAR have evaluated data from this area and see a close connection between deep currents and climatic fluctuations. More on the subject "

The surface temperatures of the North Atlantic influence the weather and climate events even in supposedly distant regions. Not only the course of winter in Central Europe, but also the strength of the cyclones in Central and Northeast America or the amount of precipitation in West Africa are largely determined by the water temperature of the North Atlantic. Water warmed up at the equator flows north and cools down again in the polar region. Since sea water has a different density depending on the temperature and salinity, cold, salty water sinks into the depths because it is heavier. More on the subject "
