冰冷的气候让山在萎缩。文章探讨了气候climate在山体腐蚀率上的作用，最后得出结论，如果气候持续变冷，则长期来看，腐蚀率会继续攀升。这篇科学类的文章观点单一，主要围绕两者之间的关系展开论证，因此难度也并不高。图表题可能同学们需要注意黑线和浅灰色区域的关系，黑线是平均值。
Sid Perkins的Cold Climate Shrinks Mountains
文章部分节选：
Every year, billions of tons of rock and soil vanish from Earth’s surface, scoured from mountains and plains and swept away by wind, rain, and other elements. The chief driver of this dramatic resurfacing is climate, according to a new study. And when the global temperature falls, erosion kicks into overdrive.
Scientists have long debated what drives most of the world’s erosion: Is it predominantly triggered by climate, or is it the result of mountain-building, tectonic activity? Most previous studies of erosion have relied on measuring the amounts of sediment that accumulate somewhere after being carried away from their sources and deposited elsewhere. But such analyses focus on the aftereffects of erosion, not the process itself, says Frédéric Herman, a geophysicist at the University of Lausanne in Switzerland. And most research has looked at limited regions of Earth—a particular mountain range, say, and not the planet as a whole.
