Climate change the culprit for Europe’s ‘most severe’ heatwave: Report

Lead

Europe’s current heatwave, described as the continent’s most severe ever tracked for the month of June, would have been “virtually impossible” half a century ago without human-caused climate change, according to a rapid attribution study released by World Weather Attribution on Friday. The international group of scientists said the extreme temperatures gripping much of Europe mark a dangerous trend that can only be explained by human-induced warming.

Coverage comparison

Three international news outlets — Africa News, Al Jazeera, and France 24 — reported on the findings, with consistent emphasis on the central role of climate change. Africa News focused on the headline conclusion that the heatwave would have been virtually impossible without climate change, citing the study’s estimate that temperatures are now around 200 times more likely than two decades ago. Al Jazeera highlighted the comparison with 1976, when a similar heatwave would have been about 3.5°C cooler during the day, and noted that the planet has warmed about 1.4°C above pre-industrial times. France 24’s coverage mirrored these figures and carried the scientists’ characterization that climate change is “unequivocally” responsible for the intensity of the event.

The outlets uniformly attributed the analysis to World Weather Attribution, a collaboration of scientists from Europe, the United States, and the United Kingdom. They also reported the lead author’s name as Theodore Keeping from Imperial College London, with Al Jazeera additionally quoting Friederike Otto, co-founder of the group, who noted that while the underlying weather pattern is not unusual, the temperatures themselves would have been extraordinary absent human-induced climate change.

Key Claims

The core finding, carried by all three outlets, is that the June heatwave would have been virtually impossible 50 years ago. The study’s analysis estimated that a heatwave of similar intensity in the climate of June 1976 — when Europe also experienced persistent high temperatures — would have been about 3.5°C cooler during the day. Al Jazeera and France 24 both reported that the planet has warmed roughly 1.4°C above pre-industrial levels, driven by the burning of coal, oil, and gas, and that this warming makes extreme weather events like heatwaves more frequent and intense.

Africa News added a statistical detail: researchers found that temperatures are now around 200 times more likely than they were just two decades ago. The same report said that nearly half of the 850 European cities analyzed have already experienced, or are expected to experience, record levels of heat stress, which combines heat with humidity.

The study also concluded that the El Niño weather pattern had no role in driving the heat, a point carried by a single outlet. The researchers warn that without a rapid phase-out of fossil fuels, even higher temperatures and their consequences are expected, and they urge governments not only to cut emissions but also to prepare societies for a hotter future.

The study’s lead author, Theodore Keeping, was quoted in Africa News’s coverage: “So we found that in the last 50 years since a previous heat wave affected Europe in 1976, that the chance of a heat wave like this has gone from almost impossible to something that we’d expect to see every couple of decades and as the climate continues to warm we will see events like this increasingly frequently and in a future climate this may be something that we expect to be commonplace.”
