Offshore wind turbines change the air and ocean currents. The rotors extract wind energy and influence surface currents, while the turbine pillars underwater act as obstacles and slow down tidal ...

In this first glimpse of the "Sea Camp" series from NPR's Short Wave podcast, hear how climate change will significantly shift three-quarters of the ocean's surface currents by the end of the century.

The world's oceans cover more than 70% of Earth's surface. They're filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine ...
