I returned from Antarctica nearly two months ago to find it considerably busier ’round these northern parts. Among the things that almost slipped past:
Dumping iron in the ocean to get carbon dioxide out of the atmosphere. It’s premature to do it commercially, and it may never turn out to be a good idea. But we could learn a lot about how the ocean works if we do some more experiments in that direction. That’s the gist of a special issue of Oceanus on the subject, in which I got to write five of the articles. Also covered: It’s become quite common to ridicule the idea for various appalling but unspecified side-effects; here are some details. Also, could it ever work? Why are economists and carbon traders interested? And what makes us think it might work in the first place?
Apparently, way more water has been dragged into the bowels of the Earth under Costa Rica than anyone ever thought before. Time was you could just dig up a handful of olivine crystals and spin the story any way you wanted – but that was before Jenn Wade got ahold of some clinopyroxenes and squeezed from them the truth. The verdict: Throw away your boron, your beryllium. Cast out your futile barium/lanthanum assays. Stop clinging to the illusions conjured in your strontium-neodymium dens. There are two kinds of magma beneath Costa Rica, and I, for one, am not going to pretend otherwise any longer. Questions? Ask the magmatic maverick herself (and check out her dancing skills) at Danger Bay.
There’s a fascinating story about whether chickens came to South America in Spanish galleons, via the Atlantic, or Polynesian outriggers, via the Pacific, here. (Thanks to El Nuthatchenyo for the tip.)
p.s. Hands up who wants to hear the best parts from Bleak House?
