Extreme heat killing more than 100 people in Mexico hotter and much more likely due to climate change – World Weather Attribution [1]
[]
Date: 2024-09
End of May and beginning of June 2024, Mexico and surrounding regions experienced extreme heat. Mexico already reported 125 heat-related deaths this season.
Extreme and persistent heat has been overwhelming south western parts of the US, Mexico, and the northern countries of Central America. The area has been lying under a large and lingering region of high pressure, known as a heat dome, whereby hot air is trapped close to the ground and further heated under blue skies and sunshine. Whilst heat domes have a well known mechanism for intensifying heatwaves, these past weeks have seen records broken in both daytime and nighttime temperatures in several countries, including Mexico, Guatemala, Honduras and in the south western US.
Heatwaves are among the deadliest types of extreme events. Even though often the death toll is typically underreported especially during or straight after the event, during this hot season Mexico has already reported 125 deaths (SwissInfo). The coinciding ongoing drought is enhancing impacts of the heat even more.
Scientists from Mexico, Panama, the Netherlands, the United Kingdom, the United States, and Sweden collaborated to assess to what extent human-induced climate change altered the likelihood and intensity of the extreme heat in a region that included the US southwest, Mexico, Guatemala, Belize, Honduras and El Salvador. Using peer-reviewed methods, we analyse 5-day maximum daytime and nighttime temperatures in May and June over a large region (see Figure 1) encompassing the region where impacts associated with extreme temperature records were reported.
