The Economist on geo-engineering

In: Uncategorized

11 Mar 2007

This week’s Economist has an interesting piece on geo-engineering in its technology quarterly (subscription required). Rather than curb emissions such techniques rely on large-scale planetary engineering to counteract climate change. Although the Economist says it was discussed in a report to the American president as far back as 1965 it is generally disliked by environmentalists. However, schemes being currently discussed by top scientists include building a giant sunshade in space, spreading tiny particles in the atmosphere to deflect the sun’s rays and blasting tiny droplets of salt water into the air.

Such ideas have previously already been discussed recently in a New York Times article and a piece on spiked. George Monbiot has also attacked geo-engineering in his Guardian column (and see my 30 August 2006 dispatch).
