巴西的森林砍伐正在削弱亚马逊的“飞航河流”, Deforestation in Brazil is weakening Amazon "flying rivers," worsening droughts across the region.

亚马逊地区的干旱,包括秘鲁、玻利维亚和厄瓜多尔的干旱,正在加剧,因为砍伐森林,特别是巴西南部的砍伐森林,断断续续的 " 飞航河流 " ,潮湿的大气流动对降雨至关重要。 Droughts in the Amazon, including in Peru, Bolivia, and Ecuador, are intensifying as deforestation—particularly in southern Brazil—disrupts "flying rivers," moisture-laden atmospheric flows vital to rainfall. 这些河流以树木喷洒为动力,向非洲大陆深处输送水,但森林覆盖率的减少削弱了水流,威胁到生态系统、土著社区和供水。 These rivers, powered by tree transpiration, deliver water deep into the continent, but reduced forest cover weakens the flow, threatening ecosystems, Indigenous communities, and water supplies. 科学家警告说,多达一半的亚马逊西部降雨量依赖于这一系统,其逐渐退化可能会使部分雨林向热带雨林般的环境转移,对气候、生物多样性和区域稳定产生严重影响。 Scientists warn that up to half of western Amazon rainfall depends on this system, and its gradual degradation could shift parts of the rainforest toward savanna-like conditions, with severe impacts on climate, biodiversity, and regional stability.
