Forbidden Research: Messing with Nature Part II: Climate

Solar geo­engi­neer­ing rests on a sim­ple idea that it is tech­ni­cal­ly pos­si­ble to make the Earth a lit­tle more reflec­tive so that it absorbs a lit­tle less sun­light, which would part­ly coun­ter­act some of the risks that come from accu­mu­lat­ing car­bon diox­ide in the atmos­phere. When I say tech­ni­cal­ly pos­si­ble, it appears that at least doing this in a crude way is actu­al­ly easy, in the sense that it could be done with com­mer­cial off-the-shelf tech­nolo­gies now, and it could be done at a cost that is real­ly triv­ial, sort of a part in a thou­sand or a part in ten thou­sand of glob­al GDP.

The Conversation #37 — David Keith

There are biol­o­gists who’ve spent their careers work­ing on some species of bee­tle in the trop­i­cal rain­for­est, and they just love the rain­for­est in their bones And they feel that when they go tes­ti­fy in Congress to some com­mit­tee, that they can’t just say, I love it in my bones and you guys will love it too, if you share it with me.” They have to say, Oh, we’ve done all this math and com­put­ed that there’s an ecosys­tem ser­vice here.” And I think that that has real­ly impov­er­ished our debate about envi­ron­men­tal issues.
