Emissions of the greenhouse gas carbon dioxide rose 18% in the United States from 1990 to 2004, with Texas and Nevada leading the way, the U.S. Public Interest Research Group reported Thursday. Texas' carbon emissions grew by 95.8 million metric tons during the period, the largest increase of any state, followed by Florida, Illinois, North Carolina and Georgia. Fast-growing Nevada ranked first for percentage growth in carbon emissions, at 55%.

Low-income families would get a chance to reduce their electric bills and help combat global warming if Southern California Edison Co. wins approval from state regulators to give away 6 million low-energy lightbulbs. The Rosemead-based electric company said Thursday that it was seeking permission from the California Public Utilities Commission to start a $22-million program to distribute six-packs of power-stingy compact fluorescent bulbs to 1 million homes across the Southland.

Global warming on Mars? It turns out you don't need belching smokestacks and city-choking traffic to heat up a planet. Changes in surface reflectivity may also do the trick, according to research published Thursday in the journal Nature. The research team, composed of scientists from NASA's Ames Research Center in Northern California and the U.S. Geological Survey, compared images of Mars taken by the Viking missions in the 1970s to pictures taken a quarter century later by Mars Global Surveyor.

President Bush, while acknowledging Tuesday that he took "very seriously" the Supreme Court's ruling that the Environmental Protection Agency must regulate greenhouse gas emissions from automobiles as pollution, set up a potential conflict with Congress by attaching two conditions to comply with the decision.

The Supreme Court cleared the way Monday for a more aggressive attack by government on global warming, which could include the first national rules to limit carbon dioxide emissions from new cars, trucks and power plants. In a 5-4 decision, the high court rebuked the Bush administration and ruled that so-called greenhouse gases -- like carbon dioxide -- were air pollutants subject to federal regulation.

Government scientists, armed with copies of heavily edited reports, charged Monday that the Bush administration and its political appointees had soft-pedaled their findings on climate change. The accusations led Democrats and Republicans at the congressional hearing to accuse each other of censorship, smear tactics and McCarthyism.

The world's six largest automakers Tuesday asked a judge to toss out a novel federal lawsuit filed by California that seeks untold millions for future damage caused to the state by global warming. In its lawsuit filed in September, California blamed the auto industry for millions of dollars it expected to spend on repairing damage from global-warming induced floods and other natural disasters.

Since the first Earth Day almost 37 years ago, U.S. companies have been eager to trumpet their environmental good deeds, even when they were more about public relations than clean air or water. But increasingly, corporate America is going green in new, serious and costly ways. After years of being prodded -- and in some cases punished -- by protesters, lawmakers, regulators and, now, even Wall Street, businesses are looking beyond the bottom line.

In a plan to curb global warming, five governors from Western states agreed Monday to work together to set a regional cap this year on carbon dioxide emissions, and join forces in a market-based emissions trading program within 18 months. The agreement came as the largest utility in Texas, TXU Corp.

A new light is about to burn more brightly: the stubby, squiggly fluorescent bulb. Environmentalists love it, Wal-Mart is promoting it and Australia is eyeing it as an easy way to save energy and curb global warming. Now, California lawmakers are giving it some wattage by considering a ban on the sale of old-fashioned incandescent bulbs beginning in 2012. The proposed switch represents a revolution in a lampshade, because incandescents account for 95% of light bulb sales.
