2008 - %3, September  Acid Oceans Also Noisier  | Tue Sep. 30,
2008 11:25 PM EDT   Increasing atmospheric CO2 increases the
acidity of seawater, which allows sounds, like whale calls, to
travel farther. Image: (c) 2008 MBARI (Base image courtesy of

absorption of atmospheric CO2 is also enabling sound waves to
travel farther. That's bad news for marine life, including
whales and dolphins, who rely on sound for hunting and
communication and who are already stressed by noisy ship traffic
and military sonar.   Advertise on MotherJones.com  Election Day

elections change the world. They also have a direct effect on

mobilized to vote. Most rely on motor vehicles to get to a
polling place. The result: an 18 percent increase in fatal motor
vehicle crashes on presidential election day.  Accordi
