Freshwater currents invade the Arctic

Washington, Jul 31 (Prensa Latina) An unusual amount of freshwater currents invading the Arctic Ocean can alter currents and temperatures in northern Europe, according to a study published in Geophysical Research Letters.
The research, carried out by the University of Colorado Boulder, in the US, sets out that climate change injects more drinking water into that portion of the sea, and its movement in decades towards the North Atlantic will alter the European climate.
The rise in Arctic freshwater in the last two decades is inexplicable and what those trends could mean for the future with impacts on ecosystems and animals, assured Rory Laiho, co-author and PhD student in Atmospheric and Ocean Sciences.
That study offers an additional perspective on what is physically happening in the ocean, which may have important implications for ocean circulation and climate.
The expert notes that since the 1990s, the Arctic Ocean has seen a 10 percent increase in its freshwater amount, which means 10,000 cubic kilometers, the same quantity needed to cover the US with 90 centimeters of water.
If too much cold Arctic freshwater currents continuously flow into the North Atlantic, rotation could be more permanently disrupted, with negative long-term effects on the climate and ecosystems in that region, the research concludes.
