Using records of sea-surface and air temperatures, researchers determined that harlequin frogs are disappearing nearly in step with the warming climate. At least 110 species of brightly colored harlequin frogs once lived near streams in the Central and South America tropics. Nearly two-thirds vanished in the 1980’s and 1990’s.

According to researchers, the Earth’s rising temperatures increase cloud cover on tropical mountains, leading to cooler days and warmer nights. This creates the perfect growing conditions for chytrid fungus–a skin fungus that causes deadly infections in amphibians.
