Global dimming is caused by a variety of aerosol species, largely anthropogenic, which get into our stratosphere and block out some of the radiation from the sun.
Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface that was observed for several decades after the start of systematic measurements in the 1950s....
Global warming does not cause global cooling. Both global warming and cooling are the results of changes in the amount of the sun's energy retained by the planet. One does not cause another.
Global warming makes the earth hotter, resulting in melting ice caps. In general it is not possible to cool something by making it warmer. Freezers and air conditioners can cool an enclosed space,...
