Tree Rings Reveal Insights into El Niño and Hurricanes
US · Published Jun 28, 2026
Scientists are using tree rings to uncover historical weather patterns, including the impacts of El Niño, hurricanes, droughts, and wildfires.
Tree cores, extracted from some of the world's oldest trees, provide data that extends weather records far beyond the era of satellite imagery.

Impact & Risks

The research highlights how tree rings can provide critical insights into the frequency and severity of hurricanes, droughts, and other natural disasters. For example, tree growth patterns reveal how hurricanes like Harvey impacted ecosystems, with slowed growth observed in the years following such events. This data is crucial for understanding long-term climate trends, especially as extreme weather events become more frequent and intense due to climate change. Regions like the U.S. Southwest and coastal areas affected by hurricanes are particularly significant for these studies, as they provide a clearer picture of how weather patterns have evolved over centuries (USA Today, 2026).
