Quick catch-up

There have been several interesting articles and discussions this week but until now I have been too busy to blog them all. Here is a quick round-up: * Debate on geo-engineering. The Royal Society (Britain’s premier science organisation) has published a series of papers in its Philosophical Transactions on geo-engineering. That in turn prompted a […]

This week’s BBC Radio 4 Analysis programme, presented by Frances Cairncross, included the most detailed popular discussion of geo-engineering I have come across so far. In broad terms three possible techniques were identified: • Removing carbon dioxide from the oceans. • Removing carbon dioxide from the atmosphere. • Using lenses or mirrors to divert sunlight […]

Evidently geo-engineering – using high technology solutions to modify the climate – is gaining interest according to a feature in the Christian Science Monitor (16 July): “Launch myriad mirrors into space to deflect a fraction of sunlight from reaching Earth. Seed the stratosphere with sulfur or other particles to cut some of the sun’s rays. […]

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. […]

It is unusual for environmentalists to want to discuss the viability of geoengineering – large scale projects designed to modify the climate – as a solution to global warming. Normally they emphasise that curbing emissions of greenhouse cases must be central to any strategy of dealing with global warming. Greens are loath to give credibility […]
