From: A recent increase in global wave power as a consequence of oceanic warming
Spatial trend (percent change per year) in mean Wave Power from 1985 to 2008. Hatched areas represent points that are statistically significant at the 95% confidence level according to the Mann–Kendall test and the Wang and Swail method for autocorrelation (see Methods). The trends are calculated for the period 1985–2008 (period with satellite-derived wave data) for comparison with9. Supplementary Figure 5 shows the spatial trends for other periods in the historical record
