The Economist has an occasional column called Green View which looks at all sorts of environmental issues, though with a preponderance of climate stuff: in the past few months we’ve looked at arctic ice, business and biodiversity, tuna farming, Svalbard (of course), Climategate, malaria and climate change, the Hartwell paper, future urbanisation and a bunch of other stuff. Since I’m the Energy and Environment Editor I sort of own this slot, though I don’t write every one of the pieces that goes in. And since there’s a lot less blogging around these parts than there used used to be, I thought some of you might like to know this.
This page lists a whole lot of the columns (and a few other things that have strayed in by mistake), but as of a few weeks ago it is probably not being updated any more due to a change in the way we publish things on line. A couple of weeks ago there was a piece on what geoengineering could mean for different regions that might be of some interest to readers of this blog. Excerpt:
Uncertainty about who might do best from what sort of project allows discussions of geoengineering to take place without the parties to the debate knowing in any detail where any nation’s specific interests might lie. This introduces what the philosopher John Rawls called a “veil of ignorance”; making decisions as if such a veil existed, Rawls thought, was a good basis for justice. (If regional outcomes could be predicted accurately, a different Rawlsian idea, that of the difference principle, might come into play. This states that just action consist not just of improving things for everyone, but specifically for improving things for the worst off, and would give the effects of geoengineering on the least developed countries a particular importance.)
And this week, rather atypically, there’s a piece on the Earth’s core, and the way things you don’t expect to be transitory turn out so to be. Excerpt:
The Earth is a recycling scheme that has been running for a third of the age of the universe. Microbes and plants endlessly pull carbon, nitrogen and oxygen from the atmosphere and pump them back out in different forms. Water evaporates from the oceans, rains down on the land, pours back to the seas. As it does so it washes away whole mountain ranges—which then rise again from sea-floor sediments when oceans squeeze themselves shut. As oceans reopen new crust is pulled forth from volcanoes; old crust is destroyed as tectonic plates return to the depths from which those volcanoes ultimately draw their fire.
Anyone who likes that second piece might want to check out the essay in Seeing Further (Amazon UK) which I blogged about here, or the Earthrise piece I did for the Times a few years ago, which also covers some similar ground. (Out of ideas, or following a ceaseless process of re-creation? You decide…)
