Impact & Risks
The altered jet stream patterns during El Niño could lead to significant weather disparities across North America. Southern regions may benefit from increased snowfall, enhancing winter sports opportunities, while northern areas like the Pacific Northwest and Canadian Rockies may face drier conditions, potentially impacting water resources and winter tourism. Warmer temperatures in northern areas could also disrupt ecosystems and agricultural cycles.
