McClatchy Newspapers reports that Columbia River Bar pilots are confirming what marine scientists have just started talking about: Ocean waves are becoming bigger and more powerful, and climate change could be the cause.
...Using buoy data and models based on wind patterns, scientists say that the waves off the coast of the Pacific Northwest and along the Atlantic seaboard from West Palm Beach, Fla., to Cape Hatteras, N.C., are steadily increasing in size.
...Similar increases in wave height have been noticed in the North Atlantic off England.
...Unclear is whether the number and height of "rogue" waves beyond the continental shelf have increased.
According to some estimates, two merchant ships a month disappear without a trace, thought to be victims of rogue waves.
