Brazil is building a complex of towers arrayed in six rings poised to spray carbon dioxide into the rainforest to understand how the world’s largest tropical forest responds to climate change.
“Plants absorb carbon dioxide along with water and light to produce sugars and release oxygen. What happens when one increases this input? We don’t know,” David Lapola, one of the leading scientists of the project, told The Associated Press. “We have evidence from similar experiments in temperate forests, but there is no guarantee that the behavior will be the same here in the Amazon.”
“Even if we halted deforestation in the Amazon basin today, the forest would still be at risk of experiencing the consequences of a tipping point due to climate change,” Lapola said. “While stopping deforestation remains our primary responsibility, combating the climate change driven by atmospheric factors is not something that Brazil or other Amazonian countries can address alone.”
