ntries is reduced and eventually capped to be in line with our 2 degree objective," he told reporters.
In its first report this year, the UN scientific panel asserted that global warming is being caused largely by the accumulation of carbon dioxide and other heat-trapping gases in the atmosphere. The second predicted catastrophic consequences unless man stops burning coal, oil and other fossil fuels that produce greenhouse gases.
Even as Ierland was taking it out on the unreasonable and obstructionist developing countries, China, generally blamed as the second largest emitter of greenhouse gases, seems to have demonstrated that it has the will to drastically pull down emission levels when it so chooses.
Satellite observations have shown that emissions of NOx, or nitrogen oxides, which are formed during combustion and thought to contribute to global warming, have come down by as much as 40 per cent.
As many as 800,000 of Beijing's 2.82 million vehicles were ordered off the road during a summit meeting on China-Africa cooperation late last year as a dress rehearsal, to try and raise the quality of air athletes breathe. Results are striking.
"We expected a drop in nitrogen emissions, but not to this extent, and after only a short period of time," said study team member Yuxuan Wang of Harvard University.
But contrast this with what is happening to Los Angeles.
It has once again topped the American Lung Association's bad air list of most polluted cities in America.
The association found that the Los Angeles-Long Beach-Riverside metropolitan area had the worst air based on 2003 through 2005 figures.
The organization based the rankings on ozone pollution levels produced when heat and sunlight come into contact with pollutants from power plants, cars, refineries and other sources. The group also studied particle pollution levels emitted from these sources, which Page: 1 2 3 4 Related medicine news :1
