Often discussed is the fact that over 93% of global warming heat goes into oceans. Not discussed are profound changes ongoing in ocean dynamics, like increased wave heights, wave periods, and wave power. Over the last 3 to 4 decades, winds at the ocean surface have increased by up to 1.5 meters/second (about 8% of 20 m/s). Wave heights have increased by up to 30 cm (about 5% of 6 meters). Increases are largest in southern oceans just north of Antarctica; also at high northern latitudes. Wave Power (Energy per unit time) has increased globally; discussed in scientific paper that I discuss in detail.
