The Guardian reports that scientists have recently confirmed that the Amazon rainforest is now emitting more carbon dioxide than it is able to absorb, and its emissions amount to a billion tonnes of carbon dioxide a year.

The giant forest had previously been a carbon sink, absorbing the airborne carbon that is driving the climate crisis. Sadly, the Amazon is now causing the acceleration of the climate crisis, researchers said.

Most of the emissions are caused by fires, many deliberately set to clear land for beef and soy production. But even without fires, hotter temperatures and droughts mean the southeastern Amazon has become a source of CO2, rather than a sink.

The scientists said the discovery that part of the Amazon was emitting carbon even without fires was particularly worrying. They said it was most likely the result of each year's deforestation and fires making adjacent forests more susceptible the next year.

The trees produce much of the region's rain, so fewer trees means more severe droughts and heatwaves, which cause more tree deaths and fires.

RUNDOWN SHOWS:
1. Dead trees and leaves releasing CO2, young tree sucking up CO2
2. CO2 rising from amazon jungle, 33% of it getting absorbed back into jungle
3. Heating planet sequence, CO2 rising from jungle, add fires, more CO2 less absorption
4. CO2 rising from jungle, jungle getting hotter, heat wave, drier, more CO2 released
5. Green, wet jungle, half gets deforested, causing remaining half to dry out
6. Continue to show remaining half drying out, heat waves, dying trees
