Climate, Air Quality, and Weather Stories September 3, 2001 EPA notes poor air quality in Acadia National Park The air quality in Acadia National Park needs improvement. That's according to federal regulators who say the park and the community of Kennebunkport posted three-year average ozone concentrations exceeding EPA standards. The ozone was measured in 1999, 2000 and 2001. Read more about it in the Kennebec Journal Online. Denver: Once smoggy city now good example There was a time Denver was second only to Los Angeles in poor air quality. But today, the city is reportedly on the brink of becoming the first major U.S. metropolis to achieve compliance with the Clean Air Act. MSNBC has the story. Is the greenhouse effect making the planet greener? Satellite data spanning two decades suggests that the Northern Hemisphere is growing greener and scientists are wondering aloud if it's a result of the enhanced greenhouse effect. NASA's Earth Observatory News Web site reports on the research which is set to appear in the September 16th issue of the Journal of Geophysical Research - Atmospheres. Offshore wind turbines could help meet U.S. energy needs A draft study by the National Renewable Energy Laboratory finds that offshore wind turbines could generate a substantial chunk of power needed to meet U.S. energy demand. The study finds that turbines placed in just three locations - New England, Lake Erie, and off the coast of the mid-Atlantic states - could generate 10-20% of the power used annually by the United States. The story appears in the latest online issue of Environmental Science and Technology Magazine. Researchers concerned about mercury in landfill gas An article in Environmental Science and Technology Magazine reports that researchers in Florida have found elevated levels of mercury in landfill gas and gas condensate. The form of mercury found in the gas, scientists report, is a precursor to "the most highly bioconcentrated form of mercury and the most common contaminant in fish in the United States and Canada." Fish is a major vehicle for mercury poisoning in humans and animals. A burning use for climate change satellite A satellite intended for climate change research is doing double duty this month. Fire fighters battling blazes in the western United States have turned to NASA's Terra Satellite for help detecting smoke, hot spots and previously burnt areas. The Washington Post has the story. |
