*Berkeley Lab joint report offers a variety of scenarios to reduce emissions to 80% below 1990 levels.*

Berkeley, CA — In the next 40 years, California’s population is expected to surge from 37 million to 55 million and the demand for energy is expected to double. Given those daunting numbers, can California really reduce its greenhouse gas emissions to 80 percent below 1990 levels by 2050, as required by an executive order? Scientists from Lawrence Berkeley National Laboratory who co-wrote a new report on California’s energy future are optimistic that the target can be achieved, though not without bold policy and behavioral changes as well as some scientific innovation.

The report, titled “California’s Energy Future—The View to 2050,” draws a series of energy system “portraits” showing how California can meet its ambitious emissions targets using a combination of measures and energy sources that may include electrification, enhanced efficiency, nuclear energy, renewable energy sources, grid modernization, and carbon capture and sequestration (CCS).

PASADENA, Calif. – Final preparations are under way for the June 9 launch of the international Aquarius/SAC-D observatory. The mission’s primary instrument, Aquarius, will study interactions between ocean circulation, the water cycle and climate by measuring ocean surface salinity.

Engineers at Vandenberg Air Force Base in California are performing final tests before mating Aquarius/SAC-D to its Delta II rocket. The mission is a collaboration between NASA and Argentina’s space agency, Comision Nacional de Actividades Espaciales (CONAE), with participation from Brazil, Canada, France and Italy. SAC stands for Satelite de Applicaciones Cientificas. Aquarius was built by NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the agency’s Goddard Space Flight Center in Greenbelt, Md.

SUNNYVALE, Calif.–(BUSINESS WIRE)— Yahoo! Inc., issued the following statement in response to recent media reports regarding the timing of the restructuring of Alipay:

On March 31, 2011, Yahoo! and Softbank were notified by Alibaba Group of two transactions that occurred without the knowledge or approval of the Alibaba Group board of directors or shareholders. The first was the transfer of ownership of Alipay in August 2010. The second was the deconsolidation of Alipay effective in the first quarter of 2011. (more…)

Aquarius to Illuminate Links Between Salt, Climate

When NASA’s salt-seeking Aquarius instrument ascends to the heavens this June, the moon above its launch site at California’s Vandenberg Air Force Base won’t be in the seventh house, and Jupiter’s latest alignment with Mars will be weeks in the past, in contrast to the lyrics of the song from the popular Broadway musical “Hair.” Yet for the science team eagerly awaiting Aquarius’ ocean surface salinity data, the dawning of NASA’s “Age of Aquarius” promises revelations on how salinity is linked to Earth’s water cycle, ocean circulation and climate.

Salinity – the concentration of salt – on the ocean surface is a key missing puzzle piece in satellite studies of Earth that will improve our understanding of how the ocean and atmosphere are coupled and work in tandem to affect our climate. While satellites already measure sea surface temperature and winds, rainfall, water vapor, sea level, and ocean color, measurements of ocean surface salinity have, until quite recently, been limited to sparse data collected from ships, buoys and a small number of airborne science campaigns.

For UCLA Expert on Chumash Indians, Roughly Hewn Beads are Child’s Play

As the world’s leading authority on beads manufactured from shells by California’s Chumash Indians, UCLA archaeologist Jeanne Arnold was stumped by a series of anomalous artifacts excavated at former settlements on the Channel Islands.

Pierced with more than one hole, often at unconventional angles or too close to the edges, the oddly configured multi-hole beads differ considerably from the smooth, round, precisely drilled beauties that served as currency among the Chumash prior to the arrival of Europeans in Southern California.

*California’s aging LGB population is set to double in next 20 years*

Members of California’s aging lesbian, gay and bisexual population are more likely to suffer from certain chronic conditions, even as they wrestle with the challenges of living alone in far higher numbers than the heterosexual population, according to new policy brief from the UCLA Center for Health Policy Research.

Half of all gay and bisexual adult men in California between the ages of 50 and 70 are living alone, compared with 13.4 percent of heterosexual men in the same age group. And although older California lesbians and bisexual women are more likely to live with a partner or a family member than their male counterparts, more than one in four live alone, compared with one in five heterosexual women.

Uncertain Future for Joshua Trees Projected with Climate Change

FLAGSTAFF, Ariz. — Temperature increases resulting from climate change in the Southwest will likely eliminate Joshua trees from 90 percent of their current range in 60 to 90 years, according to a new study led by U.S. Geological Survey ecologist Ken Cole.

The research team used models of future climate, an analysis of the climatic tolerances of the species in its current range, and the fossil record to project the future distribution of Joshua trees. The study concludes that the species could be restricted to the northernmost portion of its current range as early as the end of this century. Additionally, the ability of Joshua trees to migrate via seed dispersal to more suitable climates may be severely limited. (more…)

GAINESVILLE, Fla. — A University of Florida study demonstrates extinction’s ripple effect through the animal kingdom, including how the demise of large mammals 20,000 years ago led to the disappearance of one species of cowbird.

The study shows the trickle-down effect the loss of large mammals has on other species, and researchers say it is a lesson from the past that should be remembered when making conservation, game and land-use decisions today. (more…)
