2020年8月20日 · The Amazon Approaches Its Tipping Point. The world’s largest tropical rainforest is turning into a savanna—preventing further destruction requires urgent, multisector action. August 20, 2020

2024年2月14日 · The possibility that the Amazon forest system could soon reach a tipping point, inducing large-scale collapse, has raised global concern 1,2,3. For 65 million years, Amazonian forests...

2019年12月20日 · When it rains on the Amazonian forest landscape, at least 75% of the moisture is returned to the westward-moving air mass. The rainforest recycles the moisture five to six times before it turns southward, feeling the proximity of the high wall of the Andes.

2022年3月8日 · Large swathes could become sparsely forested savannah, which is much less efficient than tropical forest at sucking carbon dioxide from the air. The giant forest traps carbon that would otherwise...

2018年2月21日 · We believe that negative synergies between deforestation, climate change, and widespread use of fire indicate a tipping point for the Amazon system to flip to non-forest ecosystems in eastern, southern and central Amazonia at 20-25% deforestation.

2024年2月14日 · Up to 47 per cent of ‘the planet’s lungs’ could be threatened by rising temperatures, droughts, deforestation and fires by 2050, according to scientists from the Potsdam Institute for Climate...

2024年11月25日 · Scientists estimate that a 2º to 4ºC increase in average global temperatures or the deforestation of between 20% and 25% of the Amazon could trigger the tipping point; that is, endanger the survival of the entire region, transform the world’s largest rainforest into billions of tons of carbon dioxide lodged in the atmosphere and thus ...

2022年3月8日 · The Amazon rainforest is teetering on the precipice of a dangerous tipping point, new research warns. It’s gradually losing its ability to bounce back after disturbances like droughts or...

2022年9月16日 · It is increasingly reported that the largest rainforest in the world, the Amazon, is rapidly approaching a tipping point. As repeatedly highlighted by the late Tom Lovejoy (see Acknowledgements), this tipping point is where parts of the rainforest will convert into drier ecosystems due to disrupted precipitation patterns and more intense dry ...

2022年3月7日 · T hree-quarters of the Amazon rainforest may be speeding toward a “tipping point” that, if passed, could leave the world’s critical tropical biome a relatively dry savanna within a few ...
