Research from the London School of Hygiene and Tropical Medicine indicates that climate change could lead to an increase of up to 2.3 million heat-related deaths in Europe by 2100 unless significant carbon pollution reductions and adaptive strategies are employed. Regions like southern Europe, particularly Malta, Italy, and Greece, are most at risk, while northern areas might see a decrease in cold-related fatalities. The findings challenge the notion that global heating could be beneficial by highlighting a net increase in temperature-related deaths even under optimistic scenarios. Adaptation strategies including air conditioning and increased green spaces are crucial.
