El Niño is a climate phenomenon that warms up the Pacific Ocean around the equator. In the western U.S., that typically means torrential downpour; in Australia, that might mean bush fires. For the tropics, it’s associated with cycles of diseases – and now snakebites too. According to new work published in Science Advances, viper envenomation is far more prevalent in Costa Rica during both the hottest and coldest El Niño years.
