BS Nature documentary that first aired March 29 and is now available for streaming explores the impact of climate change on Yosemite National Park, and features two UC Berkeley biologists who climb to the tops of giant sequoias to understand what the future holds for these ancient trees.
Anthony Ambrose and Wendy Baxter are shown using ropes and ascenders to study the conditions of these trees hundreds of feet above the forest floor, and how these conditions are changing with a warmer and drier climate.
