Tropical forests are taking up less carbon dioxide from the air, reducing their ability to act as “carbon sinks” and bringing closer the prospect of accelerating climate breakdown. The Amazon could turn into a source of carbon in the atmosphere, instead of one of the biggest absorbers of the gas, as soon as the next decade, owing to the damage caused by loggers and farming interests and the impacts of the climate crisis, new research has found. …“We’ve found that one of the most worrying impacts of climate change has already begun,” said Simon Lewis, professor in the school of geography at Leeds University. …For the last three decades, the amount of carbon absorbed by the world’s intact tropical forests has fallen, according to the study from nearly 100 scientific institutions.
