Beijing working to clear the air
Beijing (UPI) May 2, 2008 Chinese officials said anti-pollution efforts are helping clear the air in Beijing, with 86 days of fairly good air quality reported so far this year. The Beijing Municipal Bureau of Environmental Protection said the number of so-called "blue sky" days is up from 67 during the same period last year, the state-run Xinhua news agency reported Friday. The Chinese news service said Beijing has invested $17.1 billion dollars to improve air quality. The number of "blue sky" days was 246 last year, compared to 100 days in 1998. The goal is have at least 256 days of clean air each year, Xinhua said. Related Links The Air We Breathe at TerraDaily.com
Methane Sources Over The Last 30,000 Years
Bonn, Germany (SPX) Apr 23, 2008Ice cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) were now able to identify the most important processes responsible for changes in natural methane concentrations over the transition from the last ice age into our warm period. |
