Life in the Greenhouse documents the effects of the rising concentration of carbon in our atmosphere. Season Two: Trees Remember shares the story of scientists studying what trees in the Southwest remember about drought. We investigate what tree memory means for the concentration of carbon in our atmosphere and for human life in the greenhouse we call Earth. In Season One, we use greenhouse gas accounting as a tool to analyze the hype coming from oil and gas companies about their clean energy developments, providing a crash course in emissions measurement and reduction along the way.
