From New Scientist:
GOOD news surfers: waves in the north-east Pacific are getting taller, and the height of the most extreme "100-year" waves is increasing fastest.
Previous data had shown wave height to be increasing in the north-east Pacific and north Atlantic since the late 1980s. Now measurements from a deep-water buoy moored off the Oregon coast since the mid-1970s indicate that the "100-year" waves - the monster waves with a 1 per cent chance of occurring in any given year - could be 40 per cent larger than previous estimates, at 14 metres high.
