(09/07/2009) Marijuana growers are chopping down U.S. national forests to establish plantations for illicit drug production, reports the Wall Street Journal. According to an article written by Stephanie Simon and published September 3rd, the recent border crackdown has pushed marijuana cartels to cultivate crops in the United States rather than risk smuggling from Mexico. National forests are especially targeted, with authorities uncovering marijuana farms in 61 national forests across 16 states so far this year, up from 49 forests in 10 states last year.

Review of the indoor rainforest at San Francisco's new Academy of Sciences
(11/04/2008) As a longtime resident of San Francisco's Inner Sunset district, I am quite familiar with the Academy of Sciences which is a short walk from my domicile. While I had visited it many times in its previous incarnation, the old (now demolished) museum was a far cry from the new high-tech building that opened this Fall. Both as someone who has traveled extensively in the tropics, and as the author of a number of travel guides which cover tropical rainforests and their ecosystems as well, I was looking forward to one of its most highly touted new features: the "rainforest dome."

Diversity in streams may brace Chinook salmon for climate change
(06/03/2008) Chinook salmon face a one-two punch. They have disappeared from several rivers in the western U.S. largely because of human interventions and some populations are threatened or endangered. Numbers of Chinook in California's Central Valley have dwindled by 88 percent in the past five years, a loss that closed fisheries for 2008 and may cost California's economy $167 million, according to the state Department of Fish and Game. On top of all this looms a second impact: These salmon will be in hotter water still because of climate change.
High-tech collars to reveal the secretive behvaiors of mountain lions
(05/28/2008) A handful of mountain lions in the Santa Cruz Mountains of California soon will wear high-tech collars as part of a new study by researchers at the University of California, Santa Cruz. The collars will reveal not only how these animals range within their sprawling territories, but also how they hunt. The scientists aim to figure out ways to minimize conflicts between humans and mountain lions — also known as pumas and cougars.
Why is there soot on the snowpack?
(05/22/2008) This fall, suitcase-sized air samplers will sprout throughout the Sierra Nevada. The air monitoring stations will be installed by researchers at the University of California, Davis, as part of a contract approved by the California Energy Commission (CEC) during its May 7 meeting. The researchers hope to learn whether the pollutants affecting the state's climate are coming from local sources or from transPacific sources like Asia, said Public Interest Energy Research (PIER) manager Guido Franco. The sensitive new devices will measure the amount of air pollution in the area and identify the makeup of the particles, Franco told the commission. Chemical detective work will then reveal their sources.

Wind power takes a toll on migratory bats
(09/12/2007) The danger of wind turbines to birds has long been known and well documented. Most recently several studies and articles have attempted to place the level of bird casualties in perspective: "More birds killed by cats than wind turbines". But lesser known--and lesser studied--is the effect wind turbines have on bat populations. Collisions between groups of bats and wind turbines have been observed at numerous turbines in America, Australia, and Europe. While these fatalities, sometimes killing hundreds of bats, have been seen for years, their cause remains unknown.

U.S. court blocks sonar testing to protect whales
(08/07/2007) A U.S. federal court blocked the Navy from using a type of sonar that environmentalists say pose a threat to whales off the coast of California. The judge noted that the Navy's own analyses concluded that the Southern California exercises "will cause widespread harm to nearly thirty species of marine mammals, including five species of endangered whales, and may cause permanent injury and death" and characterized the Navy's proposed mitigation measures as "woefully inadequate and ineffectual."

Inflatable concentrators may cut cost of solar below conventional power plants
(07/08/2007) Cool Earth Solar, a Livermore, California-based company developing an innovative way for capturing solar energy, has merged with Radiant Energy, a developer and owner of renewable and clean energy power plants including solar, geothermal, and hydroelectric. Rob Lamkin, CEO of Radiant Energy, says the merger will help ramp up the technology, which uses inflatable solar concentrators to minimize use of refined silicon, a costly ingredient in solar cells. Lamkin says the technology could dramatically reduce the cost solar energy, bringing it below the cost natural gas-fired power plants.
