Earth is a fire planet, but are we entering a new, dangerous age?
In short: This episode explores our planet's history with fire and how nature might adapt to a future defined by flame. By examining the relationship between humans, plants, and animals, the presenters investigate whether we are entering a new era of fire and how we might coexist with it.
Earth is unique as the only known fire planet, a phenomenon intrinsically linked to life itself. Because life produces the oxygen and organizes the fuel that fire requires, fire has existed as long as terrestrial life. This relationship is essentially biochemical, as fire reverses the work of photosynthesis by breaking down what life has built.
As the planet heats, the risks associated with fire are increasing globally, with impacts felt thousands of miles from the source. In June 2023, for instance, Canadian wildfires created significant smog across the U.S. East Coast. The episode features insights from experts including botanist Dr. Sandy Knapp, fire researcher Professor David Bowman, paleoclimatologist Nerilie Abram, and traditional fire practitioner Elizabeth Azzuz, who discuss lessons from Indigenous fire practices and the broader implications for global weather and ecosystems.
