Carbon dioxide, a main cause of climate change, makes ocean water more acidic and more efficient at transmitting sound waves. (Paul Souders / Corbis)
Add noise to the list of climate change consequences. Carbon dioxide dissolved in ocean water makes it more acidic -- and more efficient at transmitting sound waves. Monterey Bay Aquarium Research Institute marine chemists predict that by 2050, ocean sounds such as whale calls may travel 70 percent farther than today; the effect on marine animals is unknown.
