In 2024, Mexico experienced an unprecedented heatwave that led to the tragic deaths of numerous howler monkeys in the southern regions. Temperatures soared to record highs, with some areas exceeding 45°C (113°F), creating life-threatening conditions for both humans and wildlife.

In the state of Tabasco, at least 138 howler monkeys were found dead since mid-May 2024. These primates, known for their distinctive vocalizations, succumbed to heatstroke and dehydration. Veterinarians reported that some monkeys were discovered in critical condition, exhibiting severe dehydration and elevated body temperatures. Dr. Sergio Valenzuela, a local veterinarian, described the dire situation: "They arrived in critical condition, with dehydration and fever. They were as limp as rags. It was heatstroke."

The extreme heat not only affected howler monkeys but also had a devastating impact on other wildlife. In the Selva Teenek eco-park located in the state of San Luis Potosí, over 100 animals—including parrots, toucans, and bats—succumbed to dehydration. The prolonged high temperatures and reduced rainfall led to water shortages, exacerbating the crisis for both captive and wild animals.

Experts attribute these mass wildlife fatalities to a combination of soaring temperatures, drought, deforestation, and forest fires. These factors collectively deprive animals of essential resources like water and shelter, intensifying their vulnerability during extreme weather events. Wildlife biologist Gilberto Pozo highlighted the severity of the situation, noting that monkeys were "falling out of the trees like apples."

This catastrophic event underscores the profound impact of climate change on biodiversity. As global temperatures continue to rise, such extreme weather events are expected to become more frequent, posing significant threats to various species. The 2024 Mexican heatwave serves as a stark reminder of the urgent need for comprehensive climate action to protect both human and animal populations from the escalating consequences of global warming.

It’s so hot in Mexico that howler monkeys are dropping dead from trees. At least 83 of the midsized primates, who are known for their roaring vocal calls, were found dead in the Gulf coast state of Tabasco.
