Climate change is speeding up sound in the ocean. That’s bad for marine animals
0
Whales and other mammals rely on a balance of underwater sounds to survive. Climate change could be throwing off that fragile equilibrium.
For decades, the temperature of the Earth’s oceans has been rising. At the near-surface level, water has warmed by 0.14 degrees Fahrenheit per decade since 1901, a rate that’s accelerated over the past thirty years. Warmer oceans, induced by climate change, have spelled harm for marine life. They’ve killed fish, eradicated breeding grounds, and bleached coral reefs—eliminating critical food sources for organisms, and producing effects all the way up the food chain.
