According to model simulations, an eruption this large can pump so much sulfur dioxide gas into the stratosphere that the atmosphere does not have the capacity to oxidize all the SO2 to sulfuric acid aerosol.

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.

«All we need is one number — how much sulfur dioxide goes into the stratosphere — and you can measure it with satellites the day after an eruption.»

China has a plan designed to reduce pollutants such as sulfur dioxide, linked to climate change and breathing problems, by as much as 10 percent over the next five years.

«They took away from that [talk] that, on early Earth, you don't have much oxygen, but you do have sulfur dioxide from volcanism,» Ranjan recalls.

«It is therefore reasonable to expect that precipitation extremes will continue to intensify,» although how much is still a mystery, largely thanks to an unclear understanding of the atmospheric impact of how tiny flecks of pollution in the atmosphere — known as aerosols to scientists and comprising materials ranging from soot to sulfur dioxide.

The new study suggests that the impact may have released around three times as much sulfur and much less carbon dioxide compared with previous estimates from 20 years ago.

In fact, however, total emissions of sulfur dioxide were slightly lower in 1970 (15.8 million tons) than in 1980, and total emissions of nitrogen oxides were much lower (3.9 million tons).

The new research involves making a more accurate estimate of just how much sulfur and carbon dioxide gas were pumped into our planet's atmosphere following the impact.

Nitrous oxide and sulfur hexafluoride contain no carbon, yet emissions — measured by estimating how much carbon dioxide would exert the same climate effect — count in countries hitting or missing targets and the like.

According to the Chinese Centre for Disease Control and Prevention, the burning of coal is responsible for 70 percent of the emissions of soot that clouds out the sun in so much of China; 85 percent of sulfur dioxide, which causes acid rain and smog; and 67 percent of nitrogen oxide, a precursor to harmful ground level ozone.

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.

The sulfur dioxide prevented much sunlight from reaching the Earth's surface, lowering the overall temperature, and killing crops and many creatures as a result.

The benefits of the Clean Air Act have typically far outweighed the costs: According to EPA estimates, a proposal to rein in smog - causing sulfur - dioxide and nitrogenoxide would cost polluters $ 2.8 billion per year by 2014, while providing as much as $ 290 billion in health benefits to the broader public (including 21,000 fewer cases of bronchitis, 23,000 fewer heart attacks, and up to 36,000 lives saved).

A paper written by Benjamin Franklin in 1783 blamed the unusually cool summer of 1783 on volcanic dust coming from Iceland, where the eruption of Laki volcano had released enormous amounts of sulfur dioxide, resulting in the death of much of the island's livestock and a catastrophic famine which killed a quarter of the Icelandic population.

Even with much decreased numbers, the report says sulfur dioxide and nitrogen oxide emissions from coal power plants will «continue to take a significant toll on the health and longevity of millions of Americans.»

Sure enough, over time sulfur - dioxide emissions from power plants were cut almost in half, at a much lower cost than even optimists expected; electricity prices fell instead of rising.

The market for trading carbon credits will be much more complex and difficult to police than the market for the sulfur dioxide credits that eliminated acid rain.
