由于二氧化碳含量较高,亚马逊地区的树木正在扩大,增加了碳储存量,但砍伐森林和气候威胁仍然十分紧迫。 Amazon trees are growing larger due to higher CO2, boosting carbon storage, but deforestation and climate threats remain urgent.

亚马逊雨林中的树木正在扩大,平均直径每十年增加3.3%,很可能是由于作为化肥的二氧化碳含量较高。 Trees in the Amazon rainforest are growing larger, with average diameter increasing by 3.3% per decade, likely due to higher carbon dioxide levels acting as a fertilizer. 一些大学的研究人员和巴西科学家参与的一项由联合王国牵头的研究发现,小树和大树都在扩大,表明尽管气候变化,森林的复原力仍在增强。 A UK-led study involving researchers from several universities and Brazilian scientists found both small and large trees are getting bigger, indicating forest resilience despite climate change. 这种增长可能加强碳储存,但科学家警告说,毁林、干旱和养分限值威胁到长期稳定。 This growth may enhance carbon storage, but scientists warn deforestation, drought, and nutrient limits threaten long-term stability. 对碳和生物多样性至关重要的旧树不能被新种植取代。 Old-growth trees, vital for carbon and biodiversity, cannot be replaced by new plantings. 调查结果强调需要在缔约方会议第三十届会议之前在巴西保护完好无损的连接森林。 The findings underscore the need to protect intact, connected forests ahead of COP30 in Brazil.
