>In the US, thanks to the 1963 Clean Air Act, which was further updated in 1970, atmospheric levels of sulphur dioxide dropped to levels that had previously not been seen since the first years of the twentieth century One thing to remember. The US wanted CO2 to be included in this Act, but the Fossil Fuel Industry bribed (lobbied) Congress to get CO2 excluded. Dropping levels of sulfur dioxide, though was a great health benefit, made CO2 emission impacts even worse. To me, some of the article was confusing and made no point, or did I miss something ?
