Stuff I wrote elsewhere: RIP Yoda, the tree

When Henri Grissino-Mayer first told me about the tough little old Douglas fir named Yoda, it struck me as the perfect bit of anthropomorphic business for a book about tree rings for kids. When Henri emailed me last month to tell me that Yoda had died over the summer, I knew I couldn’t let the …

Questions about the Gila Diversion

In the Colorado River Basin writ large, 14,000 acre feet of water is a very small rounding error – less than one tenth of one percent of the river’s flow. But the New Mexico discussion over the possibility of a diversion high in the watershed of the Gila River in New Mexico, raises fascinating questions …

But the current debate in New Mexico illustrates a common refrain as western …

I think the answer to my rhetorical question in this post’s headline is obviously “no”. I think this is enormously useful data. But I’m still puzzling over who beyond clickbaiting bloggers like myself might use it, and how. In his coverage of the GRACE Colorado Basin groundwater depeletion, Brett Walton at Circle of Blue included …

Stuff I helped write elsewhere: Endangered Species Act litigation on the Rio Grande

From this morning’s Albuquerque Journal (behind a GoogleSurveyWall for non-subscribers, sorry): Citing “two decades of broken promises by federal and state water managers,” a Santa Fe-based environmental group filed a federal lawsuit against two government agencies Thursday alleging they failed “to secure dynamic and perennial flows for the Rio Grande” needed to protect the silvery …
