DOE and the volcano

Judith Lewis’ story “Mountain of Doubt” in the Jan. 19, 2009, issue of HCN provides an admirably accurate and balanced description of the history of Department of Energy-led efforts to establish Yucca Mountain as a safe repository for the nation’s high-level nuclear waste. Beyond the politics, Lewis explains, “Doubts about Yucca Mountain’s geologic suitability have […]

Climate Bale Out

Stuart Strand takes climate change seriously, and I’m not just talking about the groovy recumbent bicycle he rides to work. The environmental engineer from the University of Washington was searching for a way to reduce the amount of greenhouse gas in the atmosphere when he came across an intriguing report.

“1,000 messy facts”

Riparian systems are varied and dynamic; riparian models are human constructs particular to individuals. Cleo Woelfe-Erskine’s article, “Riparian Repair,” failed to capture a fundamental of reclamation and even restoration: We practitioners don’t deliver a perfect facsimile of nature full-blown at the inception but rather advance the recovery process, which continues if we have been successful […]

Late aspen, early melting

Despite the best efforts of many concerned friends, I remain something of an agnostic on whether climate change is caused by humans or is part of a natural cycle. After all, on my daily walks with the dog along the Arkansas River, I can gaze across our wide valley and stare up the narrow valley […]

Agricultural water pollution on the line

The Bush Administration has been trying since 2005 to change Clean Water Act rules so that agricultural interests can dump polluted water into public lakes and streams without obtaining a permit. Each step of the way, Florida environmentalists represented by Earthjustice lawyers have filed lawsuits to block the Environmental Protection Administration (EPA) from implementing the […]

We thought we were safe

Editor’s note: On July 9, Gordon Gregory reports that he and his family were forced to move again. The house they’d found to rent after wildfire destroyed their home on the southern edge of Paradise turned out to be in the path of a new advancing fire. I live close to tall trees in Northern […]
