Whatever Happened to Acid Rain?

From Slate:

Back in the 1980s, when the Lantern herself was just a little penlight, acid rain was the environmental scourge of the day. Canada's environmental minister proclaimed it an "insidious malaria of the biosphere"; it menaced the Transformers; it turned Kimberly's hair bright green in an episode of Diff'rent Strokes. Toxic precipitation fell off the radar in 1990, when Congress passed an amendment to the Clean Air Act calling for major reductions in the types of emissions that lead to acid rain. Emissions have dropped significantly since then, but the problem is far from gone.

Climate Change 'Own Goal': Laws To Combat Acid Rain Are DRIVING Arctic Warming, Claims Nasa

From The Daily Mail:

It is widely recognised that humans are their own worst enemies when it comes to global warming.

But the latest research from Nasa suggests laws created to preserve the environment are causing much of the damage.

Legislation to improve air quality and cut acid rain has accounted for a shocking half of Arctic warming over the past three decades, the space agency reports.

Climate scientist Drew Shindell of the NASA Goddard Institute for Space Studies in New York found that declines in solid 'aerosol' particles brought in under laws to improve air quality likely triggered 45 per cent of temperature rises.
