Analysis: Global extreme heat in June 2024 strongly linked to climate change

Between June 16 and 24, 2024, approximately 4.97 billion people—over 60% of the global population—were exposed to extreme heat that was at least three times more likely to occur due to climate change. The analysis, using the Climate Shift Index (CSI), highlights severe impacts across India, China, Indonesia, Nigeria, Brazil, and the United States, as well as lethal heat waves in Saudi Arabia, Mexico, and Egypt.

• From June 16-24, 2024, 4.97 billion people experienced extreme heat with a Climate Shift Index (CSI) level of at least 3, meaning climate change made these temperatures at least three times more likely to occur.
• The population most exposed to these climate-driven temperatures included 619 million people in India, 579 million in China, 231 million in Indonesia, 206 million in Nigeria, 176 million in Brazil, and 165 million in the United States.
• In Saudi Arabia, extreme heat led to at least 1,300 deaths during the Hajj pilgrimage, with temperatures in some cities exceeding 50°C. Analysis shows Mecca experienced temperatures at least three times more likely due to climate change every day since May 18, and five times more likely since May 24.
• Severe heat waves caused significant mortality and infrastructure strain in other regions: at least 125 people died in Mexico where temperatures reached 52°C in Sonora state on June 21; in Egypt, temperatures near 50°C led to at least 40 deaths in Aswan and forced the government to implement daily power cuts.
• India experienced one of its worst and longest-running heat waves, which ended in mid-June, resulting in over 100 deaths and more than 40,000 cases of heatstroke, with temperatures approaching 50°C.
