Disruptions in global supply chains may cause shortages of essential supplies like blood, medicines, consumables, hygiene items, oxygen, and food. Extreme weather events, such as Storm Darragh in December 2024, can prevent staff from reaching their workplaces due to hazardous travel conditions, flooded roads, and power outages and delay shift changes. Travel disruptions may also lengthen journey times to emergency sites and hospitals, intensifying the strain on healthcare services. These combined factors can severely hinder hospitals’ ability to provide timely care during climate-induced emergencies.
