Satellite Data Reveal Full Impact of Beijing Olympic Pollution Controls
Nasa researchers have shown that the highly publicised controls on auto traffic and other pollutants during the Beijing Olympics really did have a significant impact - reducing NO2 by as much as half. Some had argued that the controls had had no impact - but clearly they did, and thanks to NASA for showing us that. Here is the news from the NASA site itself.
But look at this image closely. Hmmm. One small area of China gone from red to green for just one month, while the other red areas are so big... pollution really is a major issue for China... and neighboring Japan... and the USA, where the wind blows....
And of course, pollution is just half the problem with automobiles...
Thanks to Eureka Alert for this one.
