"The Wave": The growing danger of monster waves - Our Picks: Books - Salon.com

[Q] Some people in the book claim that waves are getting bigger because of global warming. How sure are we that that's the case?

The extremes are getting more extreme. If there's a Category 5 hurricane, for example, it has the potential to be a stronger Category 5 hurricane. They haven't proved that the frequency is changing, but certainly the winds are higher. And there's really no denying a couple of things: The sea level is rising and the temperatures are rising, so there's more heat and energy in these systems. It's not rocket science.
