What does climate change mean for extreme waves? In 80% of the world, we don't really know

Across much of the world's oceans, waves are getting bigger. In the Southern Ocean, where storm-driven swell can propagate halfway across the world to California, the average wave has grown about 20cm in the past 30 years.
