U.S. power plant emissions fall

U.S. power plant emissions of sulfur dioxide dropped sharply in the first half of the year as the electricity industry prepared for tighter regulation in 2010, Genscape said Monday. Sulfur dioxide emissions were down 24 percent compared to the first half of 2008, much more than would be expected due to the recession and lower electricity demand, the power industry data provider said in its quarterly review of energy trends.

Comment on: G8 "Scorecards" Released: USA Disappoints
July 6, 2009 02:27 PM - M Molendyke, ENN Community

the World Wildlife Fund and SE- Allianz released their 2009 "G8 Climate Scorecars" report, ranking the energy performance of Canada, France, Germany, Italy, Japan, Russia, the UK and the US. Based on three categories—"Improvements Since 1990", "Current Status", and "Policies for the Future", each with specific areas for potential growth, the 8 countries were ranked based on a "stoplight" system. No country received a green light for its overall performance (half got red lights), and the tone of the report was disappointment—Although the WWF applauded efforts of top ranked countries, never did they cede that any G8 country has reached its goals or is prepared for the future. Irony abounded too when it was noted in several of the country’s reports that decreasing emissions had occurred almost by accident (due to events like Russia’s economic decline and France’s construction of nuclear power plants). Here, we have a simplified summary of each country’s performance, along with notes about each nation’s green initiatives. Read the whole article and comment at the ENN Community.

Possible Environmental Causes For Alzheimer's, Diabetes

A new study by researchers at Rhode Island Hospital have found a substantial link between increased levels of nitrates in our environment and food with increased deaths from diseases, including Alzheimer's, diabetes mellitus and Parkinson's. The study was published in the Journal of Alzheimer's Disease.

Climate body to try to bridge differences before G8

Officials from a 17-member body which account for the lions share of the world's carbon emissions will hold urgent talks next Tuesday to iron out differences on the eve of a July 8-10 summit of the G8. Group of Eight diplomats and climate change officials told Reuters the meeting of the Major Economies Forum (MEF) was called to narrow the gap between rich countries and developing nations such as India over long-term targets on global warming and emissions.

The Climate Change Debate: The History and The Forefathers
July 1, 2009 01:50 PM - M Molendyke, ENN Community

To many of us it seems as though the climate change debate is only a recent phenomena, and indeed, we have been positively bombarded by the media coverage of global warming in the past decade. Surprisingly, though, climate change speculation and study have been taking place for quite some time. In his recently published article in Weatherwise, a non-profit weather magazine, professor of geological sciences and contributing editor Randy Cerveny points out that some unexpected characters were just as concerned with weather change as we are now. Any self- respecting history buff might guess that the foremost of our founding fathers to study climate change would have been Benjamin Franklin. It all adds up—he discovered electricity, invented bifocals, and constructed the first lightning rod. However, although Franklin was an outspoken student of weather and nature, Cerveny classifies none other than Noah Webster, lexicographer and founder of the modern Merriam- Webster Dictionary, as “one of the most strident investigators on the subject of early American climate change.”

EPA Proposes New Standards for Large Ships
July 1, 2009 12:25 PM - Editor, ENN

The US Environmental Protection Agency today announced the next steps in a coordinated strategy to reduce emissions from ocean-going vessels. EPA is proposing a rule under the Clean Air Act that sets tough engine and fuel standards for U.S. flagged ships that would harmonize with international standards and lead to significant air quality improvements throughout the country. "These emissions are contributing to health, environmental and economic challenges for port communities and others that are miles inland. Building on our work to form an international agreement earlier this year, we’re taking the next steps to reduce significant amounts of harmful pollution from getting into the air we breathe," said EPA Administrator Lisa P. Jackson. "Lowering emissions from American ships will help safeguard our port communities, and demonstrate American leadership in protecting our health and the environment around the globe."

EPA proposes new one-hour NO2 standard in an effort to reduce respiratory illnesses

For the first time in more than 35 years, EPA has proposed to strengthen the nation’s nitrogen dioxide (NO2) air quality standard that protects public health.
