New elevation data triple estimates of global vulnerability to sea-level rise and coastal flooding
Research indicates a tripling in global vulnerability to sea-level rise and coastal flooding due to updated elevation data. Traditional methods underrepresent the potential impact of flooding, highlighting areas previously thought to be safe. Advanced satellite data is instrumental in identifying the true risk by providing more accurate elevation information. Over 300 million people globally are now estimated to be living on land at risk of annual flooding by 2050. Technology plays a crucial role in adaptation strategies, necessitating upgraded infrastructure and emergency protocols. The findings emphasize the urgent need for international cooperation and action to mitigate climate change impacts. Better data accuracy is imperative for future planning, requiring continual updates and refinements in elevation mapping.
