Sunlight Prevarication with Mirrors

In the US response to an IPCC draft report, SPM means Summary for Policy Makers. It could also stand for Sunlight Prevarication with Mirrors, and the comments might just as well be written by an insurance salesman.

Yesterday’s business-as-usual report on climate change in The Guardian covers this story in detail. That newspaper’s copy of the USGReview of the draft report “Climate Change 2007: Mitigation of Climate Change” (from the IPCC’s Working Group III) is what I am alluding to with my reinsuring remarks.

If solar panels were to be installed “for insurance purposes” on every building in America, they would surely reduce our energy demands and costs. Wasting time with further delaying tactics simply increases the chance that mitigation of emissions fails. The money proposed for “R&D to estimate the consequences of such a strategy” as “modifying solar radiance” would be better spent on utilising what we know now. Increased use of solar power could eliminate the need for mirrors in space—which, after all, are only replacing the natural sunlight mirrors we are destroying with our greed for energy!

Here’s a natural mirror that reflects some of the sunlight reaching the Earth. It’s the world’s largest glacier, Lambert Glacier, Antarctica. This beautiful image captured by the Landsat-7 satellite shows an icefall flowing s-l-o-w-l-y into the glacier below:
