• Days to Stretch Longer With Climate Change

    Climate change will make the day longer by the end of the century, according to a new study. Earth's atmosphere plays a large role in controlling how fast the planet rotates. As the seasons change, variations in high-level jets of wind shift, adding and subtracting about a millisecond to our day each year. >> Read the Full Article
  • Why Antarctic ice is growing despite global warming

    It's the southern ozone hole whatdunit. That's why Antarctic sea ice is growing while at the other pole, Arctic ice is shrinking at record rates. It seems CFCs and other ozone-depleting chemicals have given the South Pole respite from global warming. >> Read the Full Article
  • Southern Calif. District Reduces Water Supply, Hikes Rates

    Effective July 1, the board of directors of the Metropolitan Water District of Southern California reduced supplies its member public agencies for the first time since 1991. The financial impacts of higher Delta costs due to supply reductions caused by new regulatory restraints also were primary factors behind a rate increase approved by the board in a separate action. The rate increase will take effect Sept. 1. "Up to 19 million Southern Californians this summer will feel the impact of a new water reality that has been in the making for years, if not decades," said Metropolitan board Chair Timothy F. Brick. >> Read the Full Article
  • Atmospheric engineering scheme to combat global warming could diminish solar power

    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. >> Read the Full Article
  • CA to Secretary Salazar: No Offshore Drilling, More Renewable Energy

    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. >> Read the Full Article
  • First Wind Files Permit Application to Build a Proposed 51 Megawatt (MW) Wind Project in Maine

    First Wind today announced that it has filed a permit application with the Maine Department of Environmental Protection (DEP) to build a proposed 51 megawatt (MW) wind project in the town of Oakfield in Aroostook County. The proposed Oakfield Wind project will consist of up to 34 GE 1.5 MW turbines that can produce enough energy to power more than 20,000 homes. "Maine continues to foster the development of renewable energy, and we are excited to continue work to provide indigenous renewable and clean wind power,” said Matt Kearns, First Wind’s Vice President of Development for New England. “In addition to its many environmental and renewable energy attributes, the Oakfield Wind project will offer significant economic benefits to the state, Aroostook County, and most importantly to the Oakfield community. We are looking forward to working with members of the community to advance this project." >> Read the Full Article
  • Change is a cold certainty

    RUSSIAN sea captain Dimitri Zinchenko has been steering ships through the pack ice of Antarctica for three decades and is waiting to see evidence of the global warming about which he has heard so much. Zinchenko's vessel, the Spirit of Enderby, was commissioned in January last year to retrace the steps of the great Antarctic explorer Ernest Shackleton, marking the century of his Nimrod expedition of 1907-09. Spirit of Enderby was blocked by a wall of pack ice at the entrance to the Ross Sea, about 400km short of Shackleton's base hut at Cape Royds. Zinchenko says it was the first time in 15 years that vessels were unable to penetrate the Ross Sea in January. The experience was consistent with his impression that pack ice is expanding, not contracting, as would be expected in a rapidly warming world. "I see just more and more ice, not less ice." >> Read the Full Article
  • EPA Finds Greenhouse Gases Pose Threat to Public Health, Welfare / Proposed Finding Comes in Response to 2007 Supreme Court Ruling

    After a thorough scientific review ordered in 2007 by the U.S. Supreme Court, the Environmental Protection Agency issued a proposed finding Friday that greenhouse gases contribute to air pollution that may endanger public health or welfare. The proposed finding, which now moves to a public comment period, identified six greenhouse gases that pose a potential threat. "This finding confirms that greenhouse gas pollution is a serious problem now and for future generations. Fortunately, it follows President Obama’s call for a low carbon economy and strong leadership in Congress on clean energy and climate legislation,” said Administrator Lisa P. Jackson. “This pollution problem has a solution – one that will create millions of green jobs and end our country’s dependence on foreign oil." >> Read the Full Article
  • Climate change could worsen African "megadroughts"

    The recent decades-long drought that killed 100,000 people in Africa's Sahel may be a small foretaste of monstrous "megadroughts" that could grip the region as global climate change worsens, scientists reported on Thursday. >> Read the Full Article
  • New study warns damage to forests from climate change could cost the planet its major keeper of greenhouse gases

    The critical role of forests as massive "sinks" for absorbing greenhouse gases is "at risk of being lost entirely" to climate change-induced environmental stresses that threaten to damage and even decimate forests worldwide, according to a new report released today. The report will be formally presented at the next session of the United Nations Forum on Forests (UNFF) taking place 20 April-1 May 2009 at the UN Headquarters in New York City. >> Read the Full Article
