When lightning strikes a giant tree in the tropical rainforest, there's usually no fire, no blackened crater — you might not even notice any damage. But come back months later, as Evan Gora does, and you may find that tree and dozens around it dead. Gora, a forest ecologist who studies lightning in tropical forests, says we are just beginning to understand how lightning actually behaves in these forests, and what its implications are for climate change. On today's episode, Evan Gora tells Aaron Scott about shocking discoveries in lightning research, and why Evan has developed a healthy respect for the hazards it poses – both to individual researchers and to the forests that life on Earth depends on.
