President Bush said Wednesday that the U.S. should halt the rise in its greenhouse gas emissions by 2025, as he sought to set boundaries for global warming initiatives under consideration by Congress and major industrialized nations. But the calendar leaves him little time and, critics said, little prospect of influencing the debate. All of the presidential candidates who want to replace him favor stronger action. To reach his goal, the president said, the U.S.

California's states'-rights battle against the Bush administration over global warming was freed to move forward in federal court Friday, after the Environmental Protection Agency issued its long-delayed justification for blocking the state's 2002 law curbing greenhouse emissions from cars and trucks.

Those snazzy HEPA -- high efficiency particulate air -- filters designed for home use may actually do a body good, Danish researchers have found.

The European Union threatened Thursday to boycott President Bush's climate summit in Hawaii next month if the United States didn't allow specific targets for carbon emission reduction to be included in a draft text being prepared at a summit here this week. The text is a "road map" for negotiations to replace the 1997 Kyoto Protocol, which expires in 2012. The latest draft calls for industrialized countries to reduce emissions 25% to 40% below 1990 levels by 2020. The U.S.

As the United Nations climate conference here was drawing to its conclusion, U.N. Secretary-General Ban Ki-moon on Wednesday acknowledged that the United States' goal of deleting specific emission reduction guidelines from a draft agreement had succeeded. "Realistically, it may be too ambitious if delegations would be expected to be able to agree on targets of greenhouse gas emission reductions" here in Bali, he told reporters.

Backing up tough actions taken by Los Angeles-area ports, state regulators Friday enacted a strict air emission measure that will ban much of the current fleet of diesel trucks from all ports statewide. The California Air Resources Board will require all trucks to meet 2007 emission standards by 2014, an effort that mirrors a plan approved by the ports of Los Angeles and Long Beach.

The Bush administration must write tougher fuel economy regulations for sport utility vehicles, minivans and pickup trucks that take into account greenhouse gas pollution, a federal appeals court ruled Thursday. The decision by judges of the U.S. 9th Circuit Court of Appeals targeted a loophole that lets the top-selling vehicles, including Chevrolet Tahoe and Ford Expedition, get fewer miles per gallon of fuel than passenger cars.

Democratic presidential candidate Barack Obama today plans to propose spending $150 billion over 10 years on new clean-energy programs, including proposals to reduce greenhouse gas emissions and to develop new energy sources, according to senior campaign advisors.

State Atty. Gen. Jerry Brown, joining with national environmental groups, will petition the Bush administration today to crack down on global warming emissions from ocean-going vessels, which make more than 11,000 calls at California ports each year. The petition opens a new front in the battle by California and other states to force the federal government to regulate greenhouse gases. Until now, the focus had been on emissions from cars, trucks, power plants and other U.S.-based industries.
