UN Climate Report: We Must Focus On 'Decarbonization', and It Won't Wreck the Economy - "The basic message is simple: We share a planet. Let's start acting like it." [more inside]
Morton and Vicary on the Categorified Heisenberg Algebra - "In quantum mechanics, position times momentum does not equal momentum times position! This sounds weird, but it's connected to a very simple fact. Suppose you have a box with some balls in it, and you have the magical ability to create and annihilate balls. Then there's one more way to create a ball and then annihilate one, than to annihilate one and then create one. Huh? Yes: if there are, say, 3 balls in the box to start with, there are 4 balls you can choose to annihilate after you've created one but only 3 before you create one..." [more inside]

Recently, John Michael Greer has been exploring a little known idea of the deceased economist E.F. Schumacher (a student of the oft-discussed Keynes). "Schumacher drew a hard distinction between primary goods and secondary goods. The latter of these includes everything dealt with by conventional economics: the goods and services produced by human labor and exchanged among human beings. The former includes all those things necessary for human life and economic activity that are produced not by human beings, but by nature. Schumacher pointed out that primary goods, as the phrase implies, need to come first in any economic analysis because they supply the preconditions for the production of secondary goods. Renewable resources, he proposed, form the equivalent of income in the primary economy, while nonrenewable resources are the equivalent of capital; to insist that an economic system is sound when it is burning through nonrenewable resources at a rate that will lead to rapid depletion is thus as silly as claiming that a business is breaking even if it’s covering up huge losses by drawing down its bank accounts."

Rethinking Earthrise. On the 40th anniversary of the NASA's Apollo 8 mission [caution: weird JFK animation], which answered Stewart Brand's epochal, LSD-inspired question "Why haven't we seen a photograph of the whole Earth yet?" with an unforgettable image of a seemingly fragile and isolated blue planet, Nature editor Oliver Morton -- author of a new book on photosynthesis called Eating the Sun -- disputes the notion that the Earth is fragile and isolated. "The fragility is an illusion," he writes. "The planet Earth is a remarkably robust thing, and this strength flows from its ancient and intimate connection to the cosmos beyond. To see the photo this way does not undermine its environmental relevance -- but it does recast it."
Navarre now generates more than 50% of its energy needs by wind power: a profile of the small autonomous region in northern Spain that is leading the way in renewable energy. This is one of many free access articles in this special supplement on energy issues to the journal Nature.
