»Acid rain may counteract global warming«

British scientists say acid rain, which kills fish and damages forests, can also have a beneficial effect on the environment.

Scientists from Britain's Open University say the sulphur in acid rain, which comes from the burning of coal, may be helping to slow global warming.

It does this by restricting the production of methane gas by microbes in marshy land, such as peat bogs.

The researchers say they are not suggesting that acid rain is a good thing but pointing out that one form of pollution can help to counteract the worst impacts of another.
