Gatti's research suggests this south-eastern part of the forest, about 20% of the total area, has become a carbon source.
加蒂的研究表明,亚马孙雨林的东南部(约占总面积的20%)已经成为一个碳源。
"Each year is worse," she told Newsnight.
“一年比一年糟糕,” 加蒂告诉夜间资讯栏目。
"We observed that this area in the south-east is an important source of carbon. And it doesn't matter whether it is a wet year or a dry year. 2017-18 was a wet year, but it didn't make any difference."
“我们观察到,东南地区是二氧化碳的重要来源,而且无关年份干燥还是湿润。2017-2018年是湿润的一年,但没有什么变化。”
A forest can become a source of carbon rather than a store, or sink, when trees die and emit carbon into the atmosphere.
当树木死亡并向大气排放二氧化碳时,森林就会成为二氧化碳的来源,而不是二氧化碳的储存地或森林碳汇。
Areas of deforestation also contribute to the Amazon's inability to absorb carbon.
森林被砍伐的区域也导致了亚马孙雨林无法吸收碳。
Carlos Nobre, who co-authored Prof Gatti's study, called the observation "very worrying" because "it could be showing the beginnings of a major tipping point".
加蒂教授研究报告的合著者卡洛斯•诺布雷称,这一观察结果“非常令人担忧”,因为“它可能显示出一个重大转折点的开端”。
