This smokestack is releasing greenhouse gases and other pollutants into the atmosphere.

We can conclude that this phenomenon is not related to either pollutant.

Besides global warming, air pollution from the Indo-Gangetic Plains—one of the world’s most polluted regions is also impacting the mountains as these pollutants deposit black carbon and dust on the glaciers, hastening their melting according to the study.
