File:Atlantic Meridional Overturning Circulation at weakest point in a millennium.jpg

English: Sea surface temperature is a fundamental physical variable used to understand, quantify and predict the complex interactions between the ocean and the atmosphere. This image depicts the sea surface temperature of the North Atlantic Ocean forecasted by the Copernicus Marine Environment Monitoring Service, on 8 March 2021. In conjunction with other ocean parameters, sea surface temperature is used to map historical trends of the Gulf Stream and the wider circulatory system of surface and deep currents that it is part of, which is known as the Atlantic Meridional Overturning Circulation (AMOC). AMOC is one of the major oceanic circulation systems which redistributes heat and therefore has a major impact on our planet’s climate. A research study recently published in the Nature Geoscience scientific journal has determined that the activity of AMOC has now fallen to a historical low. Due to the effects of climate change that causes major changes in ocean currents by transporting warm water to Europe and influence storms, AMOC is now at its weakest point in the past millennium. The Copernicus Marine Environment Monitoring Service (CMEMS) provides oceanographic products and services for maritime safety, coastal and marine environment monitoring, climate and weather forecasting and marine resource uses. The CMEMS portfolio includes more than 150 products that are obtained using a combination of in-situ ocean observations, remote sensing satellite images provided by Copernicus missions and ocean forecast models, which are updated daily.
