Aircraft profiles show the eastern Amazon emitting more carbon than it absorbs

Assembled from 29 blocks · 1 evidence · 34 related

1. Story
2. Gatti and colleagues publish results from repeated vertical aircraft profiles flown over four sites through the 2010s, finding the eastern and especially southeastern basin to be a net carbon source while the wetter northwest remains a sink. Unlike a drought-year measurement, this describes a change of state in one region rather than a temporary perturbation across all of it.
