A network of more than 100 researchers tracked trees for up to 30 years in forest plots across South America, enabling estimation of the impacts of record temperatures and drought on carbon dynamics. The carbon sink in these forests ceased during the 2015–2016 El Niño, with drier forests losing the most carbon.
