Climate Madness from Steven Chu

This is the “Nobel Prize winning” physicist, who is now the US Energy Secretary in the Obama administration (don’t forget that Al Gore won a Noble Prize, as did the IPCC, which dumbs the whole thing down somewhat). Chu’s climate brainwave is to paint everything white, to reflect more sunlight back to space (no joke):

By lightening paved surfaces and roofs to the colour of cement, it would be possible to cut carbon emissions by as much as taking all the world’s cars off the roads for 11 years, he said. [What they mean, of course, is that the greater reflection of incoming solar radiation would have the same effect as reducing emissions by taking all the world’s cars off the roads for 11 years, but you can’t expect mere journalists to understand this… – Ed]

Building regulations should insist that all flat roofs were painted white, and visible tilted roofs could be painted with “cool-coloured” paints that looked normal but absorbed much less heat than conventional dark surfaces.

With guys like this in charge, we’re all in safe hands…

    Where is the part where you debunk his actual recommendation? Given the difficulty of passing meaningful legislation to reduce greenhouse gas emissions, this seems like a relatively cheap and easy recommendation that could be a small part of a much larger solution.

    Does this really need debunking? The fraction of the earth’s surface taken up by buildings suitable for painting white would be a fraction of a fraction of 1%. Painting every building white in every city on earth would make an infinitesimal difference to the earth’s albedo, ignoring the cost and inconvenience of achieving it. Cheap and easy it isn’t. And who pays for it? Governments, by raising yet more taxes? The owner of each building personally? This is a typical example of fairytale policies. Gee, I wish I had a paint factory right now…!Climate changes – it’s time we stopped blaming humanity for it and got used to it, instead of always trying to “tackle” it.
