Comment on How a false claim about wind turbines killing whales is spinning out of control in coastal Australia

They argument was that the sonar scans of the ocean floor was hurting whales, which while plausible, ignores that the navy is doing that constantly and the floor scans are temporary.

I’ve heard this in NY. What do these people think? That the whales are so annoyed by the sounds that they commit suicide?

  There are no noise-cancelling headphones to stop the U.S. Navy’s 235-decibel pressure waves of unbearable pinging and metallic shrieking. At 200 Db, the vibrations can rupture your lungs, and above 210 Db, the lethal noise can bore straight through your brain until it hemorrhages that delicate tissue. If you’re not deaf after this devastating sonar blast, you’re dead.
  
  not sure about whales, but sonar is dangerous if its loud

  There have been necropsies of beached/stranded whales which found bleeding in the ears which would make them deaf and unable to echolocate for navigation or finding food. But generally it’s blamed on Navy sonar, not temporary construction activity.
