Big waves are getting bigger.
Scientists have found that the largest waves in the Pacific Northwest are getting higher by seven centimeters a year.
Researchers at Oregon State University aren't sure why the waves are getting bigger though they think changing wind patterns may be the cause.
Bigger waves means more coastal erosion, more lost beaches, and more washed out homes and communities. Combined with a rising sea level could make for a powerful 1-2 punch on a really big chunk of human civilization.
Here's a REALLY big wave. Imagine that sucker with 7cm more water.
