Earlier this week, a few British newspapers ran stories about the implications of poor air quality in London and the impact it may have on athlete’s performance. The articles were a bit scant on details, but hinted at dangers for vulnerable populations and an increased risk of exercise-induced asthma during certain times of the day, especially for athletes. They cited London Air, a site that is tracking a number of important pollutants at sites throughout London.
They’ve got a remarkable amount of relatively easily accessible data on their site, and a special subsection catered towards visitors to London for the 2012 games. They’ve also created (in collaboration with the Environmental Health group at King’s College) free location-aware smartphone apps for Android and iOS that are impressive, easy to use, and comprehensive.

From the NYT
The heaviest rainfall in six decades caused widespread havoc in this capital over the weekend, killing at least 37 people and forcing the evacuation of 50,000 others from waterlogged neighborhoods and villages, according to the state news media.
And from BBC:
State news agency Xinhua said 460mm (18.1 in) fell in Beijing’s Fangshan district, with the capital as a whole averaging 170mm.
About 1.9m people had been affected by the downpour, and flood and economic losses had been estimated at 10bn yuan ($1.5bn, £960m), Pan Anjun, deputy chief of Beijing flood control headquarters, was quoted as saying by Xinhua news agency.
By Sunday evening, more than 65,000 people had to be evacuated. Beijing officials said 37 people had died, 25 of them from drowning.
Outside the capital, 17 people were reportedly missing in northwestern Shaanxi province and eight people dead in southwestern Sichuan province due to heavy rains, said another Xinhua report.
Here’s the real-time data, again — only useful for a few more days. Note the sudden drop in PM2.5 and the slow creep back up. More rain expected this week. Hopefully all colleagues and friends in China are keeping safe, dry, and out of the streets.
Zhang Kechun is a 32 year old Chinese photographer born in Sichuan, China. He’s created a large-format collection of photographs called “The Yellow River Surging Northward Rumblingly.” The images — with their muted tones — showcase a stunning, vast landscape mottled with people. The large intrusions and scars on the scenery — smoke stacks, superhighways, cooling towers — appear unnatural, huge, imposing. Large compared to the scale of the people in his photos, but small in comparison to the enormity of the surroundings. Really impressive work.
It is a river, with its unity of bend and straight, fullness and imperfection, rapid and slow, active or tranquil, majestic and elegant, simple and wonderful, bright and dark, light and color, form and spirit, visionary and real… It embraces people’s reality and fate, joy and sorrow, firmness and leisure.
I determined to follow its pace, with all my courage and my… large format camera.

Dave Pell, in his excellent NextDraft newsletter, points to a couple of quick and entertaining links about cities.
First, from NPR, a fun way to figure out if you live in a city.
Second, from The Atlantic Cities, a short but entertaining look at cities that may or may not have been without air conditioning. Pretty scary stuff, when we think about the rapid increase in AC use in the developing world and the concomitant strain on power supplies and use of harmful, climate forcing chemicals.
