Climate change alters how far animal acoustic signals travel.
Evidence
Even modest shifts in atmospheric conditions may have a significant impact on vocal animals and may alter the distance at which acoustic signals can be recognized and decoded. Climate change enters into play to justify such variations because climate change means modification of daily atmospheric dynamics including the distribution of rain and wind events within a season, as well as change in a season’s duration. — Bernie Krause and Almo Farina, Using Ecoacoustic Methods to Survey the…, 32
