Compromise climate bill possible
April 26, 2009 07:26 AM - Tom LoBianco, The Washington Times

Moderate House Democrats circulated a watered-down version of a sweeping climate-change-prevention bill Friday as lawmakers moved closer to a compromise on a proposal to curb greenhouse gas emissions. Meanwhile, members of the House Energy and Commerce Committee went "back to the future," turning to Democratic and Republican leaders of the '90s, former Vice President Al Gore and former House Speaker Newt Gingrich, to debate the merits of energy measures that will likely dominate the next century.

California's low-carbon fuel standard has oil companies anxious
April 25, 2009 07:59 AM - Dale Kasler , The Sacramento Bee

In car-crazy California, a new fuel standard ordered by state officials to curb greenhouse gases could dramatically change how vehicles run. It also could have a huge effect on cost. The petroleum industry and some economists say the new standard adopted by the state Air Resources Board on Thursday will cost motorists billions, because blending gasoline will become considerably more complicated.

Shell Settles Air Pollution Accusations

The oil company Royal Dutch Shell said Thursday that it had reached a $5.8 million settlement over claims of air pollution at its Deer Park refinery near Houston.

First Low Carbon Fuel Standard in U.S. Brings Cleaner Air to California

The California Air Resources Board overwhelmingly approved the nation’s first Low Carbon Fuel Standard that will reduce carbon pollution and provide cleaner air for Californians.

Fire is an important and under-appreciated part of global climate change
April 24, 2009 07:33 AM - National Science Foundation

Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that increases global temperature.

Rise in dust storms spurs environmental fears
April 23, 2009 06:57 AM - MSNBC from Washington Post

An increasing amount of airborne dust is blanketing the West, affecting how fast the snowpack melts, when local plants bloom and what quality of air residents are breathing. The dust storms are a harbinger of a broader phenomenon, researchers say, as global warming translates into less precipitation and a population boom intensifies the activities that are disturbing the dust in the first place.

Increasing levels of rare element found worldwide
April 22, 2009 07:51 AM - Dartmouth College

Dartmouth researchers have determined that the presence of the rare element osmium is on the rise globally. They trace this increase to the consumption of refined platinum, the primary ingredient in catalytic converters, the equipment commonly installed in cars to reduce smog.

Atmospheric engineering scheme to combat global warming could diminish solar power
April 20, 2009 06:23 AM - Environmental Science & Technology

A widely discussed "atmospheric engineering" scheme intended to combat global warming could have unanticipated consequences in reducing the effectiveness of certain kinds of solar power around the Earth, a new study has concluded. It is appears in the current issue of ACS' Environmental Science & Technology, a semi-monthly journal. In the study, the National Oceanographic and Atmospheric Administration's Daniel M. Murphy examines a proposal to minimize climate change by enhancing the stratospheric aerosol layer, which reduces sunlight to Earth by scattering it to outer space. But this approach has considerable implications on the ability to concentrate solar power, Murphy says. For example, the increased aerosols resulting from the 1991 eruption of Mt. Pinatubo in the Philippines reduced global sunlight by less than three percent but decreased output from some solar generating plants by about 20 percent.

Chesapeake Bay Group Wants EPA to Be Aggressive
April 20, 2009 06:10 AM - Water & Wastewater News

With its 10th annual State of the Bay report continuing to show no significant progress, Chesapeake Bay Foundation (CBF) President William C. Baker on April 15 challenged the U.S.Environmental Protection Agency to use its regulatory authority to take aggressive new action to reduce pollution. "That the Chesapeake Bay, a national treasure, remains in critical condition is outrageous. It is a national disgrace," said CBF President Will Baker. "Who are we kidding? It is 2009 and this national treasure is still getting trashed, while government refuses to use every possible tool available to stop it. When will EPA exercise its regulatory authority under the Clean Water Act to set a strict pollution reduction mandate and enforce it? Do laws mean nothing when it is only nature that is getting injured?"

CA to Secretary Salazar: No Offshore Drilling, More Renewable Energy
April 20, 2009 06:01 AM - , Triple Pundit

Last week, Secretary of the Interior, Ken Salazar, hosted the last of 4 public forums around the country to gather input on offshore drilling and offshore renewable energy development. Choosing to end in San Francisco means he is going back to Washington with a resounding “No” in his ears. “No” to offshore drilling and “Yes” to investing in renewable energy, and any other new green technology San Francisco start-ups can figure out.
