Description de l'animation:

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.
