Antonio Nobre of Brazil's National Institute for Research in the Amazon says signs of a destructive climate cycle are already detectable.
巴西国立亚马逊研究学院的Antonio Nobre表示，目前已发现气候循环破坏的迹象。

"What we are seeing already for example in southern Brazil, which is in the wake of the river of water vapor coming from the Amazon, is already a drying up. We have analyzed just ten years but you see clearly a tendency of drying."
“例如在巴西南部。我们已经观察到那些来自亚马逊河汇集而成水蒸气已经干涸。我们只分析了10年，就已经发现有明显的干旱趋势。”

Christiane Ehringhaus, who studies the Amazon for the Center for International Forestry Research, says she would not be surprised if the Amazon's future is bleaker than previously expected. She says the cycle of drying may have contributed to, and been intensified by, widespread forest fires in 2005.
为国际林业研究中心进行亚马逊研究的Christiane Ehringhaus表示，她对亚马逊会比预计更加荒凉并不惊讶。她说，干旱循环可能导致并加剧了2005年大范围的森林大火。

"You saw fires in areas of the Amazon that hadn't been detected even as flammable in previous models. So you saw forest fires that are undetectable from space that do tremendous damage and dry up the forest for subsequent fires."
“你在亚马逊区域看到的大火，甚至在早期的模型也不发现易燃情况。因此你看到的森林大火从太空中是无法觉察的，它会造成巨大的破坏，并使森林更加干燥从而导致后续的火灾。”
