Even people living far inland may be affected by the warming: droughts in the western United States seem to be caused by changing surface temperatures in the tropical Pacific.
作者总结说，随着全球温度升高，生活在热带山地山脚的物种会迁移到高地，山腰上的物种会迁移到更高的地方。
As global temperatures rise, the authors conclude, species living near the foot of tropical mountains will migrate into the uplands, and mid-elevation species will move even higher.

The Amazonian rainforest is likely to suffer catastrophic damage even with the lowest temperature rises forecast under climate change.
残留物就像一条毯子，在热带地区降低了好几度(从而帮助消除全球变暖的影响)的土壤温度。
The residue ACTS like a blanket, lowering the soil temperature by a degree or so in the tropics (and thus helping to combat the effects of global warming).
而他们所推崇的一种假说认为热带地区的温度更高意味着化学反应发生的速度更快，因此生物代谢的速率也更快。
The one they favoured is that the higher temperature of the tropics means that chemical reactions happen faster and metabolic rates are therefore higher.
过去十年里这种暴风雨的影响似乎非常明显，热带上空的对流层中最寒冷的部分温度又下降了约1度。
Over the past decade this stormy effect seems to have been pronounced, with the coldest parts of the tropical troposphere getting about a degree colder.
