High temperatures contributed to more than 47,000 deaths in Europe in 2023, according to a new study that suggests the death toll would have been even higher without mitigation measures put in place since the turn of the century.
Last year was the hottest year on record globally and among the warmest years in Europe, meaning millions of people were affected by extreme heat waves, floods and high temperatures.
Hot weather can cause medical emergencies like heat stroke, increase the risk of some infectious diseases spreading, and worsen chronic conditions like heart disease, diabetes, and asthma.
Last year, about 47,690 people died of heat-related causes, fewer than the estimated 60,000 in 2022, but a higher number than any other year since 2015, according to the study published in the journal Nature Medicine.
Researchers believe the death toll would have been 80 percent higher in 2023 if governments had not taken steps to adapt to climate change from the early 2000s onwards.
Most of the changes came after 2003, when a scorching summer led to more than 70,000 deaths and prompted many European countries to launch early warning systems and heat prevention plans.
Some steps to help people during heatwaves include improved hydration, cooler indoor temperatures, as well as broader policy measures such as climate-friendly city planning and efforts to curb greenhouse gas emissions. greenhouse.
The researchers compared the death records to weekly temperature figures and estimated how many of those deaths were the result of the heat.
In the study, Greece saw the highest heat death rate in 2023, with 393 deaths per 1 million, followed by Bulgaria (229), Italy (209), Spain (175), Cyprus (167) and Portugal (136). ).
The data comes as Greek authorities battle wildfires near Athens that have forced the evacuation of hospitals and residential areas. June and July were the hottest months on record in Greece.
