Amazon wildfires are predicted to worsen, doubling the amount of an important region of forest affected by 2050.
预计亚马逊森林大火将进一步恶化，到2050年，受影响的重要森林区域的数量将增加一倍。
The result could be to convert the Amazon from a carbon sink into a net source of carbon dioxide emissions.
其结果可能是将亚马逊从碳汇转变为二氧化碳排放的净来源。
Paulo Brando at the University of California, Irvine and his colleagues developed a model to predict how climate change and deforestation in the southern Brazilian Amazon, a wildfire hotspot, are likely to influence wildfires and their associated greenhouse gas emissions.
加州大学欧文分校(University of California，Irvine)的保罗·白兰度(Paulo Brando)和他的同事开发了一个模型，以预测巴西亚马逊(Amazon)南部的气候变化和森林砍伐可能会如何影响野火及其相关的温室气体排放。亚马逊是一个野火热点。
The model predicts a doubling in the area burned by wildfires from approximately 3.4 million hectares across the 2000s to about 6.8 million hectares in the 2040s, in the worst case scenario of deforestation and rapid climate change.
该模型预测，在森林砍伐和快速气候变化的最坏情况下，被野火烧毁的面积将翻一番，从本世纪头十年的约340万公顷增加到本世纪40年代的约680万公顷。
By 2050, the total area burned is predicted to reach 23 million hectares – 16 per cent of the existing forests in that part of Brazil.
到2050年，预计燃烧的总面积将达到2300万公顷-占巴西该地区现有森林的16%。
“We have to reduce deforestation to tackle the biggest problem,” says Brando.
“我们必须减少砍伐森林来解决最大的问题，”白兰度说。
