Roof paint

President Obama’s energy adviser has suggested all the world’s roofs should be painted white as part of efforts to slow global warming.

Professor Steven Chu, the US Energy Secretary, said the unusual proposal would mean homes in hot countries would save energy and money on air conditioning by deflecting the sun’s rays.

More pale surfaces could also slow global warming by reflecting heat into space rather than allowing it to be absorbed by dark surfaces where it is trapped by greenhouse gases and increases temperatures.

In a wide-ranging discussion at the three-day Nobel laureate Symposium in London, the Professor described climate change as a “crisis situation”, and called for a whole host of measures to be introduced, from promoting energy efficiency to renewable energy such as wind, wave and solar.

The Nobel Prize-winning physicist said the US was not considering any large scale “geo-engineering” projects where science is used to reverse global warming, but was in favour of “white roofs everywhere”.

    Ok, prove me wrong. I tried to post links to sites to illustrate my point but it was regarded as spam so I’ll give Google searches instead.

    CO2 needed for plants:
    search for “PHOTOSYNTHESIS CO2” You will see that plants require CO2 to live.

    Find a CO2 generator for greenhouses by searching for:
    “greenhouse supplies CO2 generator”

    Nuclear winter:
    search for “nuclear winter”

    Global cooling:
    search for “Newsweek 1975 global cooling”

    New Orleans snow:
    search for “New Orleans snow”. It was a very unusual event.

    Snow in Baghdad:
    search for “First snow for 100 years falls on Baghdad”

    On what point was I wrong?
