Scientists at the Potsdam Insittute for Climate Impact Research found the sea in the North Atlantic ocean is far colder than computer models predict . They say ocean currents that drive the Gulf Stream has slowed by 15-20 % . The researchers claim fresh water from melting ice sheets may be to blame . They say flow of melt water has accelerated recently due to climate change . Weakened Gulf Stream may mean more severe winters in northern Europe . Water temperatures around Florida and east coast of US could also suffer .
