The Los Angeles Department of Water and Power filed a lawsuit Friday that would limit its spending on measures to stop massive dust storms at Owens Lake. The agency argues that the Great Basin Unified Air Pollution Control District is unreasonable to order the DWP to eliminate dust on 2.9 miles of remote, geologically challenging lake bed. The DWP has already spent $1.2 billion to fulfill a 1997 agreement with the air pollution district to combat the powder-fine dust from the dry Owens Lake bed. The agency has reduced particle air pollution by 90% by introducing vegetation, gravel and flooding into vast areas of the lake bed. The 100-square-mile lake east of Sequoia National Park was transformed into dusty salt flats after 1913, when its supply of snowmelt and spring water was diverted into the Los Angeles Aqueduct.

A double-decker white tour boat sailed Wednesday afternoon toward a crescent of giant steel propellers towering above the seawater and spinning in a stiff winter wind. The boat's guest of honor, U.S. Interior Secretary Ken Salazar, rose to laud his hosts and to assure them that his country was taking steps to "get our act together" on offshore wind power. "We see Denmark as a leader and an example in wind, especially offshore," Salazar told a cabin filled mostly with European journalists and wind-energy officials.

By acknowledging over the weekend that the world would have to wait at least until next year for a legally binding treaty to curb global warming, President Obama and fellow Pacific Rim leaders dramatically lowered expectations for next month's climate negotiations in Copenhagen. Yet, in the process, White House officials and many environmentalists say, the leaders may have boosted the chances for the U.S. Congress to pass landmark limits on greenhouse gas emissions -- and for the world to act in time to stave off the worst projected effects of rising temperatures.

The state would become one of a handful to commit on its own to reducing global-warming pollution, under legislation approved in both chambers of the General Assembly. The House of Delegates voted 107 to 31 Friday for the measure, which would require the state to cut greenhouse gases 25% by 2020; the state Senate approved its version earlier this month. Lawmakers said they expected to resolve differences between the two versions and send the bill to Democratic Gov. Martin O'Malley for his signature.

Earth dodged disaster with the ozone layer, according to a NASA study about ozone-munching chemicals from aerosol sprays. NASA scientists used a computer model to find out what would have happened if the world hadn't agreed to cut back on chlorofluorocarbons 22 years ago. By 2065, two-thirds of the protective ozone layer would have vanished and the world would have been 4 degrees hotter. In Los Angeles, DNA-damaging ultraviolet radiation would have increased more than sixfold. But that dreadful scenario was "a world avoided," according to the study, published in the journal Atmospheric Chemistry and Physics.

A federal district judge will hear arguments today over whether an air-pollution control agency issued invalid emission credits to businesses and public facilities in one of California's most polluted regions.
