The El Niño weather pattern is causing ocean levels to rise, increasing the risk of coastal flooding in parts of Canada. Scientists warn that this phenomenon, combined with seasonal high tides, could create conditions for extreme flooding. The effect is most pronounced in regions with low-lying coastlines.
The National Oceanic and Atmospheric Administration (NOAA) has noted that El Niño events typically lead to higher sea levels. This year’s El Niño is among the strongest in decades. When these elevated levels meet with the highest tides of the season, the result could be more frequent and severe flooding.
Coastal communities in British Columbia, Nova Scotia, and Newfoundland are particularly at risk. These areas have already experienced increased storm surges and erosion. Local authorities are preparing for potential impacts, including property damage and disruption to infrastructure. The situation is expected to peak in late fall.
El Niño is a recurring climate pattern that occurs every few years. Its effects are part of a broader trend of rising sea levels linked to global warming. Experts say the combination of natural cycles and climate change is making coastal flooding more dangerous. The current event is a warning of what could become more common in the future.
