Forces Of Nature, a BBC co-production, will premiere on PBS on September 14, 2016, at 8:00 p.m. ET. The four-episode series illustrates Earth’s natural forces, including shape, elements, color and motion. The feature highlights the extraordinary chemical elements of our planet’s formation; the movement of tidal bores in the Amazon rainforest and the intense power of hurricanes. Forces of Nature will run through October 5, as part of a multi-title co-production deal among PBS, BBC and BBC Worldwide North America.
