The study, “Estimating US Government Subsidies to Energy Sources: 2002-2008”, found that fossil fuels benefited from approximately $72 billion over the seven-year period, while subsidies for renewable fuels totaled $29 billion. Of the fossil fuel subsidies, $70.2 billion went to traditional sources—such as coal and oil—and $2.3

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. Estimates indicate that aerosols have offset about a third of greenhouse gas-driven warming since the 1950s.
