Climate Change Is Making Oceans Louder

A recent study suggests that warming oceans are increasing the speed at which sound travels, ultimately making underwater noises louder. The world’s oceans have absorbed more than 90 percent of the excess heat that humans have produced in recent decades, causing them to rapidly warm. And in these warmer waters, sound waves are able to travel faster and farther before fading out, making the ocean a noisier, louder place. This could be especially troubling for large mammals that rely on sound and use techniques like echolocation for communication and sensing their environment.

Using publicly available global data, the researchers calculated how salt levels, temperature, and depth in seawater affect sound...
