The net result is a continuous flow of gas, starting as hot gases in intergalactic space and ending as a drizzle of cool gas called a "cooling flow," falling into the central galaxy.

In fact, even the UN's Intergovernmental Panel on Climate Change acknowledges that pollutant particles reflect sunlight back into space, which has a cooling effect.
