One smart suggestion I’ve heard, sort of a riff on cap-and-trade, is that each person has an equal right to pollute and that there might somehow be a way to monetize this. By this accounting, your average Ethiopian can sell her underpolluting ways (people in Ethiopia emit about 0.1 ton of carbon a year) to the average American (about 20 tons a year) and use the proceeds to deal with the effects of climate change (like drought), educate her kids and send them to university. (Trust in capitalism — we’ll find a way.) As a mild green, I like the idea, though it’s controversial in militant, khaki-green quarters. And yes, real economists would prefer to tax carbon at the source, but so far the political will is not there. If it were me, I’d close the deal before the rising nations want it backdated.

A Person (Dr. William Li) and a Word (Angiogenesis)

Angiogenesis is the process by which new blood vessels grow. This is good — except when it’s very bad, as in the case of cancerous tumors. Blood vessels are their supply lines. Dr. William Li of the Angiogenesis Foundation has called research in this realm the “first medical revolution of the 21st century,” and he should know. (I shouldn’t, given my lack of a medical pedigree, but I learned about it from my bandmate the Edge, who supports Dr. Li’s foundation.) Work on angiogenesis inhibitors is at the vanguard. In a world worrying about whether it can afford health care, advances in prevention are at a premium.

Factoid: Cancers start as tiny nests of malignant cells that do not enlarge until they recruit new vessels to deliver oxygen and nutrients; then a cancer can expand 16,000 times in only two weeks.

Matter Doesn’t Matter

God, it appears, is a Trekkie. (God help us.)

Dr. Anton Zeilinger, an Austrian physicist, is becoming a rock star of science for his work in quantum teleportation, which I know very little about but which I think I may have achieved backstage one night in Berlin in the early 1990s. At any rate, it seems to have something to do with teleporting properties or bits of information, not physical objects; even though Dr. Zeilinger plays down the possibility of a “Star Trek” moment, his breakthroughs are catching the attention of the nonscientific world for their metaphysical implications. His own version of E=mc2 ends in a cosmic punch line: that when it comes to the origin of the universe, information matters more than matter.

Could it be that God is a nerd?

Festival of Abraham

Here’s something that could never have happened in the Naughts but will maybe be possible in the Tweens or Teens — if there’s a breakthrough in the Mideast peace process. The idea is an arts festival that celebrates the origin of the three Abrahamic religions: Judaism, Christianity and Islam. Every year it could be held in a different location; Jerusalem would obviously be the best place to start.

In Ireland, at the height of the “Troubles,” it was said that the only solution for rabid sectarianism was to let 1,000 punk-rock bands bloom: music helped create a free space for dialogue (of a high-volume variety). So no politicians allowed. Artists only.
