Areas that depend on these systems for filling reservoirs and sustaining agriculture may face more frequent and severe droughts as their reliable moisture source becomes increasingly erratic.<\/p>\n<p>&#8220;Areas like California, especially southern regions, might experience fewer atmospheric river events, which could worsen water scarcity and contribute to prolonged drought conditions,&#8221; Li said. &#8220;The Pacific Northwest may experience more frequent and intense atmospheric river events, leading to increased risk of flooding and landslides.&#8221;<\/p>\n<p>He added, &#8220;This shift in atmospheric river activity can significantly affect water resources, agriculture and infrastructure, making it crucial for local governments to adapt to these changing weather patterns.&#8221;<\/p>\n<p>This shift also poses concerns for the Arctic region, where increased moisture from atmospheric rivers can accelerate sea ice melt. These systems may be responsible for up to 36 percent of the observed increase in summer moisture across the Arctic since 1979, potentially creating a feedback loop that could further amplify global warming.<\/p>\n<p>While natural climate variations appear to be the primary force behind these changes so far, human-induced global warming is expected to intensify the impact of atmospheric rivers in the future.<\/p>\n<p>&#8220;Atmospheric rivers are likely to become more intense in the future as the planet warms, since a warmer atmosphere can hold more moisture, leading to heavier rainfall,&#8221; Li said.<\/p>\n<p>But despite this increase in severity, whether the shift to the poles will continue remains an open question. Where atmospheric rivers land depends largely on whether the Pacific Ocean is in an El Ni\u00f1o or La Ni\u00f1a &#8220;mode.&#8221;<\/p>\n<p>Predicting these weather patterns into the future, Li said, is challenging, &#8220;but our study provides an improved understanding of the mechanisms driving the recent poleward shift.&#8221;<\/p>\n<p><strong>Do you have a tip on a science story that <em>Newsweek<\/em> should be covering?
