A new study, published Wednesday in the journal Nature, finds that regions of the eastern Amazon now output more carbon dioxide than they absorb, indicating that the planet is losing a crucial buffer in the fight against climate change.

This tipping point is the result of deforestation and acceleration heat waves.

Host Peter O'Dowd speaks with Scott Denning, a professor at Colorado State University's department of atmospheric science, about the climate crisis.

This segment aired on July 15, 2021.
