The brutal heat in Mexico is causing howler monkeys to drop dead from trees

Over the past year, an ongoing and severe drought has parched most of Mexico, draining reservoirs and leaving parts of the country grappling with an acute water crisis. Since mid-March, scorching temperatures have led to at least 26 heat-related deaths, according to the nation’s health ministry. The double-whammy of weather phenomena, scientists have warned, is aggravated by climate change — which alters usual weather patterns and results in longer and hotter periods with less rain.
