As the climate around the world changes and warm up, the animals of the world have to deal with the changes around them. The warmer climate is bad news for frogs. Droughts will be more common and frogs need rain and water. Ponds and lakes that frogs use to breed are drying up, leaving the eggs in a bad spot.
Another part of the problem with a warming climate is that Chytrid fungus might become easier to spread. Chytrid Fungus is a disease that affects amphibians. The skin of the frog becomes thick, making it hard for the frog to breath and drink through. The ideal temperature for spreading Chytrid Fungus is apparently 63° and 77°F (17° and 25°C).
