A couple of weeks ago thunderstorms dispelled the gray clouds for a day and gave Beijing breathing space to hold one of its test events for the upcoming Olympics.
The timing of the storm was not fortuitous, said one employee of the Beijing Organizing Committee for the Olympic Games (BOCOG). Rockets with silver iodide shot into the heavens had triggered it.
Cloud-seeding is just one of the measures that organizers will deploy to tip the meteorological scales and prompt blue skies over Beijing for the Olympics.
It’s a tall order, because for the past month there have been mostly gray-sky days here. The sun has been hiding, there is occasional rain and most of the time it is like living in an atmospheric potato soup.
We are in the middle of the rainy season and while organizers managed to switch the dates for the Games from July (the wettest month) to August (the second-wettest) in order to improve the prospects for good weather, there are still concerns.
China Meteorological Administration (CMA) experts are forecasting a 41 percent chance of drizzle for the opening ceremony on Aug. 8. But while cloud-seeding may prevent the clouds from raining on this parade, the biggest problem is pollution.
The city has experienced breakneck development over the past 30 years and this has increased since being awarded the right to hold the Games in 2001.
The number and scale of new buildings erected over the past seven years are impressive. Increased wealth means more people in cars; the number of automobiles has swollen to 3.3 million. More power stations and factories have been constructed to fuel this prosperity.
This is undeniably good for the economy but bad for air quality and there is no silver bullet solution.
Organizers promised the International Olympic Committee (IOC) that air quality for the Games would be within WHO standards, and much has been done in this regard.
Many of the most polluting factories have been moved out of the city, hundreds of thousands of homeowners have switched from oil to gas heating, and emission standards for vehicles have been raised.
In support of what they are calling a “Green Olympics,” organizers point to the impressive 6.7m² Olympic Forest Park that has just opened. They also mention planting hundreds of millions of trees to provide 50 percent “green coverage” in the city.
In the past 10 years, they claim, pollutants such as sulfur dioxide have been reduced by 61 percent, carbon monoxide by 39 percent and inhalable particulates by 17.8 percent.
City officials say US$17.5 billion has been spent on pollution reduction measures over the same period, but others point to the gray skies and argue it has clearly not been enough.
IOC president Jacques Rogge has generally been supportive of the organizers but even he was moved to say last year that pollution was still an issue and suggested endurance events would be rescheduled if conditions were bad.
In response, Games organizers are insisting it will be all right on the night(s) because further measures controlling pollution will be introduced.
From this Sunday large-scale construction and spray painting in the city will stop, gas stations will be closed if they haven’t instituted oil vapor recovery upgrades and quarrying will be halted.
In addition, 70 percent of government motor vehicles will be taken off the road and cars will be banned on alternate days according to whether their license plates end in odd or even numbers.
