For more than a decade, I’ve written about arguments over whether the United States is building, or could, or should build “new” nuclear weapons. They are frequently silly arguments. The “newness” debate was engaged in earnest in the late 1990s when the weaponeers fielded a nuclear bomb called the “B61 Mod 11”. The B61 is …

While I’ve been away, my friends back in Albuquerque were kind enough to print a bunch of copies of my ruminations on La Niña and the Rio Grande and throw them on people’s driveways this morning (sub/ad req): [M]ore than La Niña is at work this year, according to Glen MacDonald, a climate researcher at …

One of the guys at the Las Vegas Marina yesterday was sounding optimistic. Sure, the lake level’s low, he said, but they expect it to start rising soon. Plus, he said he heard they expect it to eventually come up another 60 feet. He shrugged as if to say, “Dunno, but that’s what I heard,” …

Down a long, dank corridor inside Hoover Dam that seems to be known as the “1211 tunnel” (things in the dam tend to be named after their elevation above sea level) and up a flight of stairs sits the top of the dam’s “stilling well”. It’s essentially a long tube that runs to the bottom …
I’m about to head off for a few days to watch Lake Mead drop, and for some reason thoughts turned this evening to G.K. Gilbert. Tomorrow is “blog action day“, and the subject is “water”, a topic about which I’ve had a few things to say of late. I’m frankly not all that excited about …
“Water year” 2010 ends next week, making this a good time to take stock of our historic position on the Colorado River. And by a couple of different measures, things are truly historic: The latest forecast (and right now forecasting amounts to tiny fractions of in inch) puts Lake Mead’s surface elevation at 1084.14 feet …

With La Niña rapidly strengthening, it is reasonable to ask what can be said about the resulting effect on flows in the Colorado River. The short answer: not much. It is reasonable to guess otherwise, because so much of the southwest depends on the Colorado for its water supply, and because La Niña is so …
Speaking at a symposium in Las Vegas in April, former Bureau of Reclamation Commissioner Bob Johnson made a critical point about the differences between water problems on the Colorado River and the current struggles in the southeast over the Apalachicola-Chattahoochee-Flint and Alabama-Coosa-Tallapoosa river basins. The ACT-ACF fights made the Economist this week, in an article …
In an interview over at Grist, Brad Udall reminds us that, as we think about the effect of climate change on the West, it’s not just the thorny question of whether precipitation rises or falls that matters. Despite the uncertainties surrounding that question, as temperatures rise (a projection about which there is considerably less uncertainty), …
