Recent research reveals that the intense heat waves scorching the southwestern United States, southern Europe, and China this summer would have been “virtually impossible” without climate change.
Scientists from the World Weather Attribution group, who analyze extreme weather events, found that these heat waves have been significantly intensified by global warming.
For instance, the extreme heat in China’s Xinjiang region, which could have been expected once every 250 years in a stable climate, is now happening more frequently due to rising global temperatures.
Friederike Otto, a climate scientist at Imperial College London and contributor to the study, emphasized that climate change plays a crucial role in these unprecedented weather patterns.
The findings, published on Tuesday, suggest that heat waves as severe as those in Phoenix, Catalonia, and Xinjiang could now occur once every 15 years in the U.S., once every 10 years in southern Europe, and once every five years in China.
The study, while not yet peer-reviewed, aligns with previous analyses from the group that have passed rigorous academic scrutiny.
The research highlights how global warming is creating conditions for more frequent and severe heat extremes. Scientists warn that these extreme weather events are likely to become even more common as greenhouse gas emissions continue unabated.
The summer of 2024 has already set numerous records, including the hottest June and unofficially the hottest days in July.
Phoenix has experienced a record 24 consecutive days of temperatures exceeding 110°F, while a township in Xinjiang reached a staggering 126°F, setting a national record. The intense heat has led to power outages, crop losses, and disruptions across affected regions.
Julie Arrighi from the Red Cross Red Crescent Climate Centre stressed the need for governments to improve adaptation strategies to manage the increasing frequency and severity of these extreme weather events.
