“Miracle May” leaves Colorado River reservoirs in much better shape than when the month started
A month that Eric Kuhn of the Colorado River Water Conservation District in western Colorado called a “miracle May” has left the Colorado River’s two largest reservoirs in much better shape than we might have expected given the glum projections of doomsayers like me. Precipitation across the Colorado River Basin has been well above average, …
Tree Rings and Megadroughts
Mount Holyoke’s “Academic Minute” has a nice interview with Park Williams, who’s been using tree rings to flesh out the story of the current drought in the context of historic droughts, as it pertains to forests in the Southwest: I study the year-by-year records left by these rings, and they tell a fascinating story more …
California ag showing remarkable resilience
Amid the rhetoric of doom, California agriculture has so far been growing its way through drought: Even as many farmers cut back their planting, California’s farm economy overall has been surprisingly resilient. Farm employment increased by more than 1 percent last year. Gross farm revenue from crop production actually increased by two-tenths of 1 percent …

For the first time since 2011, less than half of New Mexico in drought
For the first time since January 2011, less than half of New Mexico is classified in “drought” this morning in the weekly federal “Drought Monitor” (“drought” is the oranges and browns): Driving back across the state from a meeting in Arizona last week, things looked greener than I’ve seen in a long time, though I …

New Mexico’s Rio Grande, on the rise (finally)
Water from our recent storms, combined with the some clever twiddling by federal and local water managers, is pushing the Rio Grande through Albuquerque in the next few days to the highest spring runoff levels we’ve seen since 2010. Water managers are taking advantage of the May storms to add some water and create a …

“Enough water will never be enough”
California’s water problems will never be solved Faith Kerns and Doug Parker argue, because cities and farms will always expand to the edge of available supply, overshoot, and then face trouble during the dry times: There are other arenas where this phenomenon is well understood. For example, when it comes to freeways, congestion leads to demand …
In defense of “vapor pressure deficit”
If you follow weather forecasts, you’ve heard about “relative humidity” (RH). But it’s one of those maddeningly less-than-useful measures of our weather that probably needs to be just retired. That’s wishful thinking, of course. But in an interesting introduction to their latest research into the increasing dryness of the air and the risk of fire …
Sound of a Warming World
Daniel Crawford and Scott St. George at the University of Minnesota have collaborated on another fascinating attempt to use music to communicate data about our warming world: Todd Reubold at Ensia has more on the project.
Warm in the West, but not as dry as you might have thought
update: Jeff Lukas, in the comments, notes that I missed something important, which is the distinction between statewide averages and the east-west precip divide. As he correctly points out, that statewide blob of wet-looking Colorado hides the fact that it’s been extremely wet to the east, and relatively dry west of the continental divide. Here’s …
