The Fern That Cooled the Planet

The video explores a significant climate shift 50 million years ago, potentially caused by Azolla ferns. These ferns thrived in the Arctic Ocean, absorbing large amounts of CO2 and contributing to global cooling. The video discusses the discovery of Azolla fossils, their impact on ancient climate, and their modern applications, including potential climate mitigation.
