Switzerland: A recent scientific study has revealed that the searing heatwave that engulfed Europe last summer resulted in the deaths of more than 60,000 individuals, highlighting the lethal impact of rising global temperatures exacerbated by greenhouse gas emissions.
In Europe’s hottest summer on record, alarm bells were sounded by EU statisticians in August 2022 as sweltering heat, prolonged droughts, and rampant fires engulfed the continent, leading to a significant increase in mortality rates. Public health experts then employed epidemiological models to determine the number of deaths attributed to the extreme temperatures. The study found that between May 30th and September 4th, 2022, 61,672 people in Europe died from heat-related causes. Italy, Greece, Spain, and Portugal recorded the highest mortality rates. Heat-related deaths were predominantly caused by pre-existing health conditions, such as heart and lung diseases, that were exacerbated by the extreme heat.
Throughout the summer of 2022, the study highlighted that average temperatures in Europe consistently exceeded the baseline values of the previous three decades. The most intense heatwave occurred from July 18th to 24th, claiming the lives of 11,637 individuals.
Europe has experienced a temperature rise almost twice as fast as the global average due to human-induced climate change. To prevent even deadlier heatwaves, governments must take measures to protect their populations from rising temperatures and reduce greenhouse gas emissions.
While the study’s analysis has been commended, some experts believe the actual death toll may be higher. Weekly data used in the study may have diluted the impact of short-term temperature spikes. A separate study revealed that daily data analysis in Spain indicated 10 percent more heat-related deaths than suggested by the weekly data. Another study conducted in Switzerland demonstrated an even more significant effect, with daily data estimates doubling the death toll compared to weekly data estimates.
Both the Swiss study and the Europe-wide analysis found that women, particularly older women, were more susceptible to heat-related deaths. The Swiss research also highlighted that pollution resulting from fossil fuel burning and environmental degradation contributed to the increased mortality rate.
Addressing climate change and its impacts on vulnerable groups is crucial for saving lives. Strengthening healthcare systems and fostering community support networks can provide vital protection during extreme weather events, such as heat waves.
