AN EARLY warning sign for the loss of plants in the Amazon rainforest can be seen in the temperature difference between seasons, according to the latest climate models. " This is the first time these climate models have predicted localised dieback events" Some of the climate models that Parry and her team used also predicted localised dieback events, where certain areas in the northern region of South America appeared to show forest death. As well as finding evidence of forest dieback events in north-western Brazil, southern Colombia and northern Peru, Parry and her team noticed that a strong indicator of dieback events was when the gap between the highest and lowest annual temperatures in a certain region grew larger (arxiv.org/abs/2203.11744).
