Stratosphere wind changes affect seas and climate, study shows

Alterations in the speed of the Atlantic circulation pattern, called the Atlantic Meridional Overturning Circulation, which affects seas around the world as it acts in a similar way to a conveyor belt, transporting water around the earth. These can happen several years running or miss a decade, so adding this decade-scale effect into climate modelling is important in forecasting decade-to-decade climate changes that are difference from global warming, says Thomas Reichler. "If we as humans modify the stratosphere, it may - through the chain of events we demonstrate in this study - also impact the ocean circulation. "Good examples of how we modify the stratosphere are the ozone hole and also fossil-fuel burning that adds carbon dioxide to the stratosphere. These changes to the stratosphere can alter the ocean, and any change to the ocean is extremely important to global cli...
