It might soon be time for a revision of Pilot Charts. NatGeo tells us:
Europe and North America may soon experience chillier temperatures, thanks to natural North Atlantic variations that could temporarily mask the effects of human-driven, or anthropogenic, climate change.
“We believe that ocean currents and systems could, in the short term, change global warming patterns and even mean temperatures,” said Noel Keenlyside of the Leibniz Institute of Marine Sciences in Kiel, Germany.
Keenlyside explained that since record keeping began in the 19th century, the North Atlantic climate has changed in natural cycles that last a decade or more.
These shifts are likely associated, at least in part, with natural variations in ocean currents.

IMC has a very complete post on alternative energy ideas for harnessing power from our oceans. They tell us;
Wave power refers to the energy of ocean surface waves and the capture of that energy to do useful work - including electricity generation, desalination, and the pumping of water (into reservoirs). Wave power is a form of renewable energy. Though often co-mingled, wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents. Wave power generation is not a widely employed technology, and no commercial wave farm has yet been established (although development for the first commercial wind farm in the Orkneys are well under way).
