Climate Change Unequivocally Linked to Western Europe's Intense Heatwave, Study Finds

An international scientific network has concluded that climate change is unequivocally responsible for the intense heatwave currently gripping Western Europe. The study, published by the World Weather Attribution (WWA) network, states that such extreme temperatures would have been virtually impossible approximately 50 years ago.

Scientists from WWA, who investigate the role of human-induced climate imbalances in extreme weather phenomena, found that the current daytime and nighttime temperatures would have been highly improbable in 1976, a year that also experienced exceptional heat. Their calculations suggest that if a similar heatwave had occurred then, it would have been about 3.5°C cooler during the day and 2.4°C cooler at night.

We concluded that over the last 50 years, during which the planet's temperature has increased by 1.1°C, the probability of such a heatwave occurring has changed dramatically.

"We concluded that over the last 50 years, during which the planet's temperature has increased by 1.1°C, the probability of such a heatwave occurring has changed dramatically," said Friederike Otto from Imperial College London, a participant in the research. She emphasized that a heatwave of this magnitude in June would not have been possible without climate change.

A heatwave like this would not have been possible in June without climate change.

Western Europe has been experiencing extremely high temperatures for over a week, caused by a large mass of hot air originating from Africa. Otto noted that while such weather events are not unusual, the temperatures themselves are abnormal due to human-caused climate change, primarily driven by the heavy use of fossil fuels like coal, oil, and gas, as well as deforestation.

The study, which involved scientists from several European countries, utilized current meteorological data and future forecasts. Researchers compared this data with records from 2003 and 1976. While the findings have not undergone external peer review, the methodology has been validated by the scientific community. The research indicates that extreme daytime heat is now ten times more likely, and hot nights are one hundred times more likely compared to the 2003 heatwave.

This weather phenomenon is not unusual, but the temperatures are due to human-caused climate change.
