Greenhouse Effect

April 7, 2007 | John Johnson Jr., Times Staff Writer
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.

California is preparing to label new autos to show for the first time the vehicles' annual emissions of so-called greenhouse gases linked to global warming. The stickers, the first in the U.S., should be approved by the California Air Resources Board by June and should start appearing on 2009 model cars and light trucks, board spokesman Jerry Martin said. The board will hold a hearing next month on the labels.

Republican presidential candidate John McCain was anything but subtle Wednesday as he took swipes at the Bush administration during a meticulously staged appearance with Gov. Arnold Schwarzenegger on the bustling docks of Los Angeles Harbor. President Bush's record on global warming? "Terrible," McCain declared. His pursuit of the Iraq war? "A train wreck."
