Last year I detailed just how miserable winters can be in China (here). Windows are left open or don’t even close to begin with, buildings lack any kind of insulation, and space heaters are required just to keep your tea from freezing. The problem is that China’s people are now actually expecting to be comfortable at home and work (I don’t blame them), but the amount of energy required to accomplish that is going to be astronomical given the lack of energy efficient buildings. In fact, just the other day a senior gov’t planner described 95% of China’s new buildings as “energy-guzzling,” and that China is building  2 billion square meters of this type of building each year (that doesn’t account for old buildings which […]


The top story this week was the Shanghai metro crash which I covered in a recent post. The accident reignited the debate about the speed with which China is building infrastructure. Adam Minter reflected on the greater meaning of the crash for Shanghai residents who have no choice but to commute to work on the subway in his piece “Shanghai rail commuters get onboard with a prayer“. China also launched the first components of its new space station, which should be fully operational around the time the International Space Station is decommissioned. This great technological accomplishment coming on the heels of a needless crash creates an interesting contrast between technical achievements, and the ability to manage and maintain these systems. The cost of development was also […]


On Friday morning I was taking a group of foreign guests to visit sites around Nanjing when a heavy smog blanketed the city in a yellow stench. It seemed as if every family in the city of over 7 million had lit a pile of tires ablaze. Within 20 minutes of being outside I started feeling asthma like symptoms, meaning that it actually hurt to breathe. After the experience I was eager to check the official Air Quality Index (updated daily) to see just how severe the pollution had been. Unfortunately, these are not posted in a timely enough manner to be of any use in avoiding this kind of hazard. So you can imagine my surprise in learning that “officially” the air quality on Friday was […]


Pollution is something that has really become a concern for me here in Nanjing. The main reason for this is that I have had a sore throat and cough for about 3 months, and after x-rays and blood tests I have been declared healthy, even though I feel far from that. I blame pollution for this, since that seems to make more sense than the ideas my co-workers have come up with. One thought it was because I work in a hospital, which isn’t the worst idea, except that I am not even in the same building as patients. Another thought was that I don’t wash my hands enough, which simply isn’t true, thoroughly washing my hands like a surgeon while wearing my doctor’s coat […]
