Poleward North Pacific Storm Shift Outpaces Climate Models

New analysis using decades of sea-level pressure data shows North Pacific winter storm tracks are migrating north toward the Arctic faster than climate models project, a shift linked to climate change that coincides with Alaska’s glacier ice loss (~60 billion tons per year) and hotter, drier conditions across California and Nevada. The study suggests models may understate the risks of storm-track changes, implying Western North America could face more dramatic impacts than current projections indicate.
