Summary

Description
English: NASA's MODIS satellite instrument reveals how air pollution may alter clouds, affecting global temperatures. This narrated visualization illustrates the effect by showing how ship exhaust leaves bright cloud trails in clean ocean air. The ship tracks themselves are too small to affect global temperatures, but they help us understand how larger pollution sources might change clouds on a bigger scale.

中文（简体）：NASA 的中解析度成像分光辐射计显示空气污染会怎么影响云层，及全球气温。这个视觉化叙述展示船只废气在干净的大洋空气中留下云朵痕迹。这艘船轨迹造成的影响小到无法影响全球气温，但让我了解大规模的污染源在大尺度下怎么改变云朵。
