The West African nations of Mali and Burkina Faso experienced an exceptional heat wave from April 1 until April 5, with soaring temperatures above 45 degrees Celsius (113 degrees Fahrenheit) triggering many deaths. Observations and climate models used by researchers at the WWA showed that "heat waves with the magnitude observed in March and April 2024 in the region would have been impossible to occur without the global warming of 1.2C to date", which scientists attribute to human-induced climate change. While periods of high temperatures are common in the Sahel at this time of year, the report said that the April heat wave would have been 1.4C cooler "if humans had not warmed the planet by burning fossil fuels". It added that the five days of extreme heat was a once-in-a-200-year event, but that "these trends will continue with future warming". The length and severity of the extreme heat led to an increase in the number of deaths and hospitalizations in the two countries, despite their populations being acclimatized to high temperatures, the WWA said. Deaths in heat wave A lack of data in the affected countries made it impossible to know the exact number of deaths, the WWA said, adding there were likely hundreds, if not thousands, of other heat-related casualties. "From April 1 to 4, we saw an increase in the use of services," Djibo Mahamane Diango, head of anesthesia at Gabriel Toure hospital in the capital Bamako, told reporters on April 5. He said the hospital had seen the arrival of 102 bodies—more than half of them people aged over 60—during the first four days of this month. That compares with 130 for the whole of the month of April the previous year, he added. The April heat wave in Mali—where the temperature spiked at 48.5 degrees Celsius—and neighboring Burkina Faso coincided with the holy month of Ramadan when Muslims fast from dawn until dusk.
