WASHINGTON -- Emissions of heat-trapping greenhouse gases from power plants fell 10% from 2010 to 2012, as a result of more electricity being generated with natural gas rather than coal, according to new data released Wednesday by the Environmental Protection Agency. Fossil-fuel-fired plants still contribute 40% of carbon dioxide and other emissions driving climate change, making them the single largest source of greenhouse gases, the EPA said. The data arrive as the EPA crafts new rules, at President Obama's behest, to curtail greenhouse gas emissions from power plants.

WASHINGTON - The Supreme Court has agreed to hear a utility industry challenge to the Obama administration's environmental regulations that would limit greenhouse gases coming from power plants and factories. The justices agreed to rule on whether the Environmental Protection Agency's restrictions involving motor vehicles give the agency the power to impose similar restrictions on “stationary sources that emit greenhouse gases,” which would include everything from power plants and refineries to apartment buildings and factories.

Re "What's this global warming 'hiatus'?," Sept. 23 I'm not a climate scientist and will not attempt to argue the interpretation of the data presented in this piece, but I do know what the word "hiatus" means: merely a lapse in continuity - in this case, with the extent of global warming predictions. This is by no means an excuse to continue burning fossil fuels in lieu of using clean, renewable energy sources. If my doctor told me to stop smoking or I'd be dead by age 50, and I ended up turning 51, does that prove he's wrong and I should continue smoking?

WASHINGTON - Last year was one of the 10 hottest since global average temperatures have been recorded, according to an assessment of worldwide climate trends by the National Oceanic and Atmospheric Administration. "The State of the Climate in 2012," released Tuesday, paints a sobering portrait of vast swaths of the planet transformed by rising temperatures. Arctic sea ice reached record lows during the summer thaw. In Greenland, about 97% of its ice sheet melted in the summer, far greater than in years past.

Hydroelectric dams may be known as a relatively clean and low-cost energy source, but a new study says that the sediment trapped behind them makes them hot spots for greenhouse gas emissions. A team of European scientists found that methane, which is produced by organic matter in the sediment that collects behind the impoundments, bubbles up through the water and contributes more of the greenhouse gases driving climate change than previously thought. The scientists studied six small dams on the River Saar in Germany and found “hot spot emission zones” of methane, a potent greenhouse gas that is many times more effective at trapping heat than carbon dioxide.

Ford Motor Co. plans to start selling its popular F-150 pickup truck with an option of running on natural gas or propane fuel. While Ford already makes the option available in some of its commercial vehicles, this will be the first compressed natural gas, or CNG, model sold by the automaker that has considerable retail sales. Ford sells about 70,000 gasoline-powered F-series trucks every month. Its sales top all other vehicles in the U.S. While Ford says some consumers will probably order the CNG model, most of the customers will be businesses.
