非洲森林从2010年至2017年因砍伐森林而变成碳源,对气候目标构成威胁。 Africa’s forests turned into carbon sources from 2010–2017 due to deforestation, threatening climate goals.

《自然》的一项新研究发现,由于伐木、耕作和基础设施的增长,2010年至2017年期间,非洲雨林和热带草原从碳汇转变为排放源,特别是在刚果民主共和国、马达加斯加和西非。 A new study in Nature finds Africa’s rainforests and savannas turned from carbon sinks to sources of emissions between 2010 and 2017 due to logging, farming, and infrastructure growth, particularly in the DRC, Madagascar, and West Africa. 卫星数据表明,这些生态系统现在释放的碳比吸收的碳还多,威胁着全球气候目标。 Satellite data show these ecosystems now release more carbon than they absorb, threatening global climate goals. 虽然巴西的反毁林努力保持了亚马逊碳汇的地位,但除非加强治理、可持续做法和供资 — — 比如1 000亿美元的热带森林永久融资机制 — — 得到改善,否则非洲的森林损失有可能使气候变化恶化。 While Brazil’s anti-deforestation efforts have preserved the Amazon’s carbon sink status, Africa’s forest loss risks worsening climate change unless stronger governance, sustainable practices, and funding—like the $100 billion Tropical Forest Forever Facility—improve.
