North Pacific winter storm paths are moving toward the North Pole faster than scientists expected.<\/p>\n

In Alaska, glaciers are losing about 60 billion tons of ice each year. Farther south, across California and Nevada, heat and dryness records are falling, leaving landscapes more prone to wildfire. These changes may seem separate, but both are tied to a major shift over the North Pacific Ocean.<\/p>\n

Winter storm tracks, the usual paths followed by powerful weather systems, are moving northward. These storms act like atmospheric conveyor belts, carrying heat and moisture from warmer parts of the planet toward the pole. As their paths shift closer to the Arctic, Alaska receives more of that heat and moisture, while the southwestern United States loses some of the natural atmospheric flushing that helps moderate temperatures.<\/p>\n

Storm shift outpaces models<\/p>\n

Research published in Nature by Dr. Rei Chemke of the Weizmann Institute of Science\u2019s Earth and Planetary Sciences Department and Dr. Janni Yuval of Google Research finds that this northward movement is happening faster than climate models have projected.<\/p>\n

To test whether the shift was part of ordinary climate swings or a sign of human-driven warming, the researchers used a new metric based on sea-level pressure, a measurement that has been collected consistently for decades. That long record gave them a way to separate background variability from a lasting climate signal. Their analysis indicates that the storm track shift is not natural variability, but a clear result of climate change.<\/p>\n

Models may understate risk<\/p>\n

The result fits with several earlier studies by Chemke suggesting that storm tracks are changing quickly and that climate models may not fully capture those changes. That matters because storm tracks help shape where heat, moisture, drought, and storms concentrate, especially across western North America.<\/p>\n

\u201cOur preparedness for future climatic change relies on the ability of models to make accurate predictions,\u201d Chemke says. \u201cThe fact that models fail to capture the effect of climate change on the recent northward shift of storm tracks \u2013 and its consequences for western North America \u2013 suggests that changes in this region may be even more dramatic than we currently expect.\u201d<\/p>\n
