2010年以来,由于森林砍伐,非洲森林从碳汇转变为净排放者,对全球气候目标构成威胁。 African forests turned from carbon sinks to net emitters since 2010 due to deforestation, threatening global climate goals.

非洲森林曾经是主要的碳汇,但自2010年以来,由于森林砍伐和退化,特别是刚果民主共和国、马达加斯加和西非各地热带潮湿宽叶森林的砍伐和退化,非洲森林自2010年以来已成为碳的净排放者。 African forests, once major carbon sinks, have become net emitters of carbon since 2010 due to deforestation and degradation, particularly in tropical moist broadleaf forests across the Democratic Republic of the Congo, Madagascar, and West Africa. 利用卫星数据和机器学习进行的一项研究发现,从2010年至2017年,非洲每年损失约1 060亿公斤树木生物量,相当于1.06亿辆汽车,这逆转了先前的碳收益,破坏了全球气候目标。 A study using satellite data and machine learning found Africa lost about 106 billion kilograms of tree biomass annually from 2010 to 2017—equivalent to 106 million cars—reversing a prior carbon gain and undermining global climate goals. 由农业扩张、野火和薪材采伐驱动的这一转变突出表明,迫切需要扩大气候融资,加强森林治理,并扩大热带森林永久融资机制等保护努力,该基金旨在筹集1 000多亿美元,但迄今只获得65亿美元。 The shift, driven by agricultural expansion, wildfires, and fuelwood harvesting, highlights the urgent need for expanded climate finance, stronger forest governance, and scaled-up conservation efforts like the Tropical Forest Forever Facility, which aims to mobilize over $100 billion but has so far secured only $6.5 billion.
