The searing temperatures in Brazil, which have persisted for about a week, have set a slew of monthly and all-time temperature records, according to weather historian Maximiliano Herrera.
The high pressure ridges driving the extreme temperatures were similar to those that bogged the U.S. this summer, when places like Phoenix registered temperatures over 110 F for more than three weeks at a time. Climate change increases the odds of heat waves and can make them more intense.
The World Weather Attribution Network analyzed a heat wave in South America this September and found that climate change had dramatically increased the odds of such a dramatic stretch of heat. The group found that temperatures would have been between 2.5 and 7.7 F cooler had humans not warmed Earth by consuming fossil fuels and emitting carbon pollution.
The World Weather Attribution group studies extreme weather and publishes rapid findings about climate change’s role in major events using peer-reviewed methods.
The past 12 months have been the hottest in modern history, according to the nonprofit organization Climate Central. Scientists believe the effects of El Niño, a natural climate pattern that releases ocean heat into the atmosphere, has begun to take hold and contribute to heightened temperatures.
In Brazil, El Niño typically has caused drought in northern parts of the country and extreme rainfall in the south, the Associated Press reported. Drought in the Amazon has dried up waterways this season, and fires have been burning in parts of the country’s tropical wetlands.
Many households in Brazil lack technology to cool their homes. About 20% of the country’s households owned air conditioning in 2018, according to a study in Nature Communications.
Swift rescheduled a show slated for Saturday in Rio de Janeiro and instead took the stage on Monday.
The incident left an impression on prominent voices in the climate community.
“Today would be a good day for Taylor to say a few words to her zillions of fans about the risks of life on a fast-warming planet and why we need to stop burning fossil fuels,” wrote Jeff Goodell, the author of the climate change book “The Heat Will Kill You First”, on x.com.
