“Nowhere to go except heaven”

Under pressure from habitat loss and climate change, California butterfly diversity is falling fast at low elevations, according to an analysis by UC Davis lepidopterist Arthur Shapiro.
Meanwhile, according to the study, to be published by the Proceedings of the National Academy of Sciences, butterfly diversity is actually going up at tree line. The cause, reports the UC Davis news service, is lower-elevation species reacting to the warming climate by moving upslope to higher, cooler elevations.
However, there is only so high they can go and the report also finds that diversity among high elevation butterflies is falling as temperatures become uncomfortably warm for them and, Shapiro says, “There is nowhere to go except heaven.”

Whiskey’s for drinking at CBS
Whiskey is for drinking, water is for fighting
No sooner has Lesley Stahl snapped shut her dictionary of Twain quotes* used in the recent CBS show “60 Minutes” on the California water crisis as it’s been opened again to the same page — this time by the network’s Atlanta-based reporter Mark Strassmann for a CBS Evening News broadcast.
This time one of the figures driving the network to drinking cliches is the Southern Nevada Water Authority’s general manager Pat Mulroy, who will appear on CBS Evening News tonight to discuss American water shortages, including those of her agency covering Las Vegas. Those who don’t buy that serving unfettered development in the Mojave Desert qualifies her as a conservationist may need to start drinking now. To see how heavily, click here.

Saints to bow to Vegas, reports flagship LDS paper
SALT LAKE CITY — A proposed water-sharing agreement in Snake Valley between Nevada and Utah appears destined for signature by the two states as additional revisions were aired in a Wednesday meeting of an advisory council, reports the Deseret News.
Nevada officials indicated at the Snake Valley Advisory Council meeting that they are on board with the agreement as it stands, and John Harja, chairman of the council, conveyed that Utah Gov. Gary Herbert is convinced that “an agreement is better than none, and the interests of Utah are best served by an agreement.”

Speculation aside, there is still hope that Utah Governor Herbert won’t sign. The Great Basin Water Network was founded …
