A good argument

Via Brad Plumer, this might be the most honest, good-faith argument about nuclear power I've read in the last, oh, year or so. You can read Max Schulz's pro-nuclear argument here, and then read the anti-nuclear side by Bruce Smith and Arjun Makhijani.

No surprise, I come down on the anti-nuclear side myself, but at least Schulz doesn't simply ignore or refuse to acknowledge the real risks of nuclear power (waste, proliferation, costs). And in his reply at the bottom of Smith and Makhijani's piece, he makes a reasonable argument that Smith and Makhijani are soft-pedaling the costs associated with wind's intermittency.

Can we live with skyscraper farms?

I find ideas like this stimulating, if only because it shows some creativity: skyscraper farms.

Basically, the idea is to build multi-story enclosed greenhouses near the cities where most food is consumed, thus reducing the acreage required to grow the crops and the energy needed to transport them. Some of the work done by Columbia University suggests the "vertical farm" could produce at least twice as much energy as it consumes from burning the biomass wastes.

Tunnels everywhere!

First a train tunnel between Africa and Europe, now the Russians want to build the long-dreamt-of tunnel between Russia and Alaska. The tunnel would theoretically carry natural gas, oil, electricity, and fiber-optic wires.

The more and better tunnels we have for rail, the more competitive rail will be with less efficient transport systems like air travel. This is better for energy efficiency and therefore the environment.

This project still has a lot of problems -- it's not like there's a lot of spare rail up above the Arctic Circle, necessitating lots of construction -- but I'm sure Ted Stevens is already salivating.

On Revkin’s piece on poverty and climate change impacts

(A topic I return to every once in a while. See here and here.)

The link that Jason posted Sunday deserves a closer look, if you missed it over the weekend. Revkin has written an excellent, if somewhat depressing, piece on the fact that while climate change is overwhelmingly the responsibility of the world's rich nations, the nations that suffer most will be the world's poorest.

It also reminds me of something else I heard Tim Flannery say last week: whatever else we know about climate change, we know that it will stress nations, and stressed nations sometimes do horrible things. The solution to climate change must therefore necessarily be a multilateral one.
