    Do we need fuel cells & hydrogen?

    This should be reason enough for even the non believers in global warming

    Air pollution is harming people with weak hearts - even killing them, a big international study reveals.

    Experts estimate the toll includes thousands of Britons each year.

    The British Heart Foundation, which funded The Lancet work, says the UK must clean up its air - many of its cities often exceed safe levels set by the European Union.

    The government has already admitted that in 15 regions, air quality will breach EU limits until 2020.

    But Defra says it is committed to improving air quality and that most parts of the UK meet EU air quality limits for all pollutants.

    Air pollution, largely from traffic fumes, has previously been linked to heart attacks but not heart failure.

    This happens when the heart muscle becomes weak and less good at its job of pumping blood around the body. It is often the consequence of a heart attack and affects more than 750,000 people in the UK.

    Deep into lungs

    The Lancet research looked at 35 studies with data for thousands of patients in 12 countries, including the UK, the US and China.

    The strongest link was found with gases such as carbon monoxide and nitrogen dioxide, as well as fine particulate air pollution - fumes from buses, taxis and lorries that can get deep into the lungs and, from there, into the bloodstream.

    People with already weakened hearts who were exposed to high levels, by living near to or travelling along busy roads, for example, were particularly susceptible.

      another idiot out pumping fuel cells -- YAWNNNN!!!!

    • BEIJING (AP) — A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5½ years less than their southern counterparts because they breathed dirtier air.

      China itself made the comparison possible: for decades, a now-discontinued government policy provided free coal for heating, but only in the colder north. Researchers found significant differences in both particle pollution of the air and life expectancy in the two regions, and said the results could be used to extrapolate the effects of such pollution on lifespans elsewhere in the world.

      The study by researchers from China, Israel and the United States was published Tuesday in the Proceedings of the National Academy of Sciences.

      While previous studies have found that pollution affects human health, "the deeper and ultimately more important question is the impact on life expectancy," said one of the authors, Michael Greenstone, a professor of environmental economics at Massachusetts Institute of Technology.
