UCSD Installs Solar Trees;

The University of California, San Diego, which strives to be one of the nation’s “greenest” college campuses, is installing solar trees on the roof of two of its parking garages.

Fresno State completed a similar installation last year.

Steel components at the Uiversity of California have already taken shape, forming frameworks that will soon be fitted with a canopy of Kyocera photovoltaic modules to provide energy for the campus.

Each solar tree at UCSD will generate more than 17,000 hours of energy per year; enough to power more than four single-family homes; and avoid 13.2 metric tons of carbon emissions.

In addition, the design offers the option to install an outlet for electric vehicle charging.

The solar tree is the creation of Envision.

Parking lots are seen as a prime location for solar power installations. Google has installed solar canopies on its parking lots to satisfy 30 percent of its headquarters’ power demand.

US scientists sign petition rejecting "global warming"...

More than 31,000 scientists across the United States, including more than 9,000 Ph.D.s in fields including atmospheric science, climatology, Earth science, environment and dozens of other specialties, have signed a petition rejecting "global warming," the assumption that the human production of greenhouse gases is damaging Earth's climate.

"There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate," the petition states. "Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth."

The Petition Project actually was launched nearly 10 years ago, when the first few thousand signatures were assembled. Then between 1999 and 2007, the list of signatures grew gradually without any special effort or campaign.
