The golden toad (bujo periglenes), was a small, shiny creature that lived in high-altitude cloud-covered tropical forests above the city of Monteverde in Costa Rica. Today it has the dubious title of being the first species believed to have been made extinct by current climate change. Alone male was found in 1989, and despite extensive searches, not one of the toads has since been tracked down. About two-thirds of the 110 harlequin frog species across Central and South America have died out after contracting a fungal infection thought to be triggered by climate change. But while amphibian populations could be hit the hardest by global warming, conservationists have said up to one-third of amphibians are in danger, these creatures are hardly alone.
