Drilling into the Greenland ice sheet, researchers reconstructed the jet stream's past
New U.S. National Science Foundation-funded research provides insights into how the position and intensity of the North Atlantic jet stream have changed during the past 1,250 years. The findings suggest that the position of the jet stream could migrate outside of the range of natural variability by as early as the year 2060 under unabated greenhouse gas emissions, with potentially drastic weather-related consequences for societies on both sides of the Atlantic.
