"The authors report that the occurrence of extensive deforestation in tandem with climate change will cause the remaining rainforest to lose resilience at global-warming levels of or slightly higher than 1.5 °C — rather than 4 °C — above pre-industrial levels".

"Earth’s forests reached a tipping point. They had grown dense, lush canopies at the start of one of Earth’s most intense episodes of greenhouse warming. But those canopies began to thin." "The structure of a forest – and importantly its canopy – controls the amount of light that reaches the forest floor, the temperature, water habitat and amount of carbon the forest can store, making it one of the clearest indicators of ecosystem function." "Forest canopies opened, exposing the ground to more sunlight and altering the movement of water through the landscape." "As temperatures climbed, heat and drought overwhelmed the benefits of higher carbon dioxide levels. The canopy rapidly thinned as trees died, and it remained much thinner for over 100,000 years." "Ancient soils gave way to coarser river deposits". Regan E.
