The Lamont-Doherty group that has done so much to help our understanding of the factors that drive multi-decadal droughts has added a nice piece to our understanding of the issues. In a paper in review (for which they’ve done a nice accessible writeup), Ben Cook and colleagues looked at a number of drivers for long-duration …
The final Heineman-Fleck backyard precip tally for 2011 is 6.03 inches (15.3 cm). That’s 61.5 percent of the long term average, where by “long term” I mean back to 2000. It is the driest year in my record, just a smidge under 2002’s 6.21 inches (15.8 cm). Only two months, October and the just-completed (I …
Let me suggest a positive narrative to the story of Texas’ great drought of 2011. The Texas Commission on Environmental Quality today released its latest list of communities whose water supplies are threatened as a result of the driest year on record. Topping the list is tiny Groesbeck, between Dallas and Houston, where a line …
When I was thinking about how to write a book about climate science for kids, measuring the weather made sense to me. As a journalist, it’s my favorite science to write about because of the opportunities to tie science to everyday experience. And any kid can set up a thermometer and rain gauge in their …
In New Mexico, we make our snowmen out of the materials at hand: (updated with a link to the video because I can’t figure out how to embed it right)
Corey Pieper, a National Weather Service meteorologist in Texas, linked this evening to some excellent (if grim) maps showing what it would take to bring Texas, New Mexico and the rest of the southern tier of states out of drought. The first is the percent of normal precipitation required over the winter to end drought: …

Given the time scales associated with climate change and societal response, it seems perhaps best to wait to consume the new IPCC Special Report Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) until it’s actually done. This seems especially true given its stated purpose: The assessment concerns the interaction of climatic, environmental, and human …
I’m thinkin’ you’ll want to head out to your favorite local bookstore and buy Bill deBuys’ A Great Aridness. It’s full of stuff like this, on the dry winter of 2001-02, when a bear came out of hibernation early because it was so warm and ransacked deBuys’ yard in search of something to eat: That …
Because it’s hard to resist the word “megadrought” – or, frankly, the concept: Tree rings from the headwaters of the Rio Grande show a 50-year drought from 122 to 172 AD, suggesting that “megadroughts” may be a recurring feature of the region’s climate, according to new research by a University of Arizona team. Scientists have …
I had occasion this evening to revisit “Sensitivity of Streamflow in the Colorado Basin to Climatic Changes,” by Linda Nash and Peter Gleick, circa 1991: Water availability, quality, and demand may be affected by higher temperatures, new precipitation patterns, rising sea level, and changes in storm frequency and intensity. Water supply and water management in …
