There are a number of possible reasons for a worldwide drop in the population of amphibians. High levels of ultraviolet radiation, and Chytrid and other types of infections could be causes. Amphibians may have become more susceptible to infection as a result of weakened immune systems. Amphibians have previously adapted to climate change, though changes in climate may make them more vulnerable to diseases.
