Acid rain arises when sulfur dioxide and nitrogen oxides (NOx), emitted by burning fossil fuels, react with water droplets in the air to form sulfuric and nitric acid.

Human activities emit about two times as much sulfur dioxide into the atmosphere, according to co-author Vitali Fioletov, an atmospheric scientist at Environment and Climate Change Canada in Toronto, Ontario.

Natural gas is much more environmentally friendly than coal, which continues to be the mainstay of electricity production around the world and in the U.K. Gas emits less than half the CO2 per kilowatt hour produced, and it emits much lower amounts of other pollutants like nitrous oxide, sulfur dioxide, black carbon, carbon monoxide, mercury, and particulates.
