The Bureau of Reclamation has tuned up its estimates of the chances of release of extra water to help Lake Mead, now putting them at one in four this year, according to an update published today (Wed. 2/10). The jargon here is “equalization,” which happens when there is enough extra water upstream in Lake Powell …

As a native Southern Californian with a deep attachment to its deserts, this paper is just heartbreaking. Lesley DeFalco of the USGS and colleagues describe the effect of variable climate extremes and wildfire in the last decade on populations of desert plants, most especially Yucca brevifolia – the Joshua Tree: Accentuated ENSO episodes and more …
The median forecast for flows on the upper Colorado River, out this morning, is 5.8 million acre feet, 73 percent of normal. That is down 400,000 acre feet from a month ago, and represents a continued reduction in the probability that there will be extra water upstream to pass down to replenish Lake Mead. Flows …
With a half an inch of snow in the back yard this morning, I’m reminded of one of my favorite bits of data-gathering described in my book. In addition to the stories of scientists who study western climate, we included activities for young people to do for themselves. Weather and climate are the most accessible …
From this morning’s Albuquerque Journal, a story (sub/ad req.) about new research suggesting that, in the past, the jet stream moved north and what is now the southwestern U.S. dried out when the world was warmer: For 45,000 years, the drips built stalactites and stalagmites in Fort Stanton Cave. The minerals in the rocky deposits …

In my book, The Tree Rings’ Tale, in addition to sharing the stories of scientists I tried to give young readers examples of science they can do themselves. As a science journalist, I got hooked on weather years ago because the sciency bits connect so nicely to readers’ everyday experience. It’s just one short step, …
It’s far too early in the season to draw any conclusions regarding 2010 runoff. The first serious forecasts don’t come out until January, and with months of snowmaking weather still to come, no one takes the January forecast terribly seriously. But this is a blog, so I won’t let that stop me. Currently, the NRCS …
It’s Science Saturday in the Albuquerque Journal. By which I mean that, when editors wander the halls looking for copy to fill the holiday news doldrums, there’s always an extra science feature on offer. (sub/ad req if you follow the links) VLA gets an upgrade: Rick Perley had a big smile on his face as …
Emily Green had some kind words for my book in the LA Times: Many texts about climate change begin with rapidly melting polar ice, but Fleck’s opens instead with the 19th century explorer John Wesley Powell and his navigation of the Colorado River. Ferociously wild in Powell’s time, the Colorado is tamed by dams and …

One of the points that Mickey Glantz makes is that drought, as a societal rather than a meteorological event, requires not just the rain to fail, but also a society’s institutions. So what’s happening in South America right now, in particular the political fallout from a reduction in precipitation, is intriguing. From Ecuador: A drought …
