[Carbon soot](http://en.wikipedia.org/wiki/Soot “Wikipedia Article”) from China is warming and polluting the atmosphere over the Pacific Ocean and all the way to North America, according to a new study.

The airborne soot dims sunlight reaching the surface, causing cooling there, but it also heats the air higher where it resides, resulting in an overall heat gain for the climate.

The effect on the Pacific Ocean, the largest and most influential ocean on the planet, could have global climate implications.
