Global warming is the increase in emissions of greenhouse gases (GHG) emissions, caused mainly by industrialized societies.

Global dimming is a term that describes the gradual reduction of the observed amount of sunlight reaching the earth's surface since the mid-1950s. It is thought to have been caused by an increase in particles such as carbon black (or charcoal) in the atmosphere due to human activities, primarily burning.

the problem is that, if it will reduce the Global dimming, can to increase Global Warming and the glaciers are defrosted. but if reduce Global Warming , We can die very cold.
