Arizona Illustrated - Water management in the border regions
The lead P.I. (Gregg Garfin), the Border region chapter lead author (Margaret Wilder), and the Border region chapter Review Editor (Robert Varady) for the "Assessment of Climate Change in the Southwest United States" report discuss some of their research on understanding and planning for water resource management across the US-Mexico border with the PBS program Arizona Illustrated. Their interview as well as a fascinating primer by Tom Swetnam on paleoclimate via tree ring characteristics can be viewed here - http://playpbs.azpm.org/video/2233279400Their report, " Moving Forward from Vulnerability to Adaptation: Climate Change, Drought, and Water Demand in the Urbanizing Southwestern United States and Northern MexicoCase Studies in Ambos Nogales, Puerto Peñasco, Tucson, and Hermosillo" is available for free download here: http://udallcenter.arizona.edu/sarp/pdf/Casebook.pdf |

Mt. Baldy Wilderness and the super moon
We spent a few days backpacking in the Mt. Baldy Wilderness. We followed the west fork of the Little Colorado running strong on fresh snow melt to its headwaters and on up through alpine meadows to the spruce and fir covered Mt. Baldy saddle. Despite the devastation that the combination of abiotic drought stress and biotic bark beetle kill has caused on the beautiful evergreen forests, this place is at once recognizable as sacred land - as it has been since the first humans walked here. Turbulence felt the call of his ancestors as he rampaged in the meadows looking for elk. We camped at the summit and watched the rare giant moon rise up to greet us as we warmed ourselves by the fire. Here is a short photo slideshow: http://fileshar.es/Wi3a8EB |

Isoprene, back to the fundamentals
While trying to find "everything under the sun" that is released by plants into the atmosphere, the ecosystem metabolomics laboratory at Biosphere 2 is also going back to the fundamentals of plant primary and secondary carbon metabolism by studying isoprene. Isoprene (2-methyl-1,3-butadiene) is a highly reactive organic gas that is produced and released by many plant species in huge quanties. So much so that it accounts for an estimated 1/3 of all organic emissions from all natural and human sources (biogenic and anthropogenic). The image shows Prof. Kolby Jardine standing in front of isoprene (the 5 carbon molecule with two double bonds) and it's mass spectrum which represents a "fingerprint" that can be used to identify it's presence using GC-MS. |

human-electric hybrid
Human hybrid systems are the wave of the future!. Below, I'm making some grocery runs in my system that I developed over the last year. We hope to go on a long bike tour this summer! |
