Guardian: Global warming is set to stall over the next 10 years as natural variations in ocean currents counteract manmade climate change. Researchers modelling the climate of Europe and North America found that a major ocean current that brings warm water northwards is set to weaken, potentially offsetting temperature rises caused by human activity. A team led by Noel Keenlyside at the Leibniz Institute for Marine Science in Germany focused on an ocean current known as the meridional …
