The Power of a Tweet

In a follow up to yesterday’s post about the disappearing pollution documentary in China, it’s interesting to note that it was a US Embassy Twitter feed that jump-started the conversation and concern about the growing problem of air pollution in China.

A recent article in Wired tells the story in a post titled How the US Embassy Tweeted to Clear Beijing’s Air. Here’s a short excerpt:

WHEN THE US Embassy in Beijing started tweeting data from an air-quality monitor, no one could have anticipated its far-reaching consequences: It triggered profound change in China’s environmental policy, advanced air-quality science in some of the world’s most polluted cities, and prompted similar efforts in neighboring countries.

As the former Regional Strategic Advisor for USAID-Asia, I have seen first-hand that doing international development is incredibly difficult. Billions of dollars are spent annually with at best mixed results and, even with the best intentions, the money often fails to move the needle. That is why I was so inspired by the story of the US embassy’s low-cost, high-impact development project. They tapped into the transformative power of democratized data, and without even intending to, managed to achieve actual change.

Here’s how it happened.

In 2008, everyone knew Beijing was polluted, but we didn’t know how much. That year, the US Embassy in Beijing installed a rooftop air-quality monitor that cost the team about as much as a nice car. The device began automatically tweeting out data every hour to inform US citizens of the pollution’s severity (@beijingair).

For the first time in China, publicly available data focused on one of the most dangerous types of air pollutants, PM2.5—airborne fine particles less than 2.5 microns in diameter or about the thickness of a spider web’s thread. These tiny particles are small enough to penetrate your lungs and even enter your blood stream, causing serious cardiovascular and respiratory ailments. In fact, experts have recently shown that air pollution is responsible for more deaths worldwide annually than malaria and HIV combined.

In 2010, it became official: Beijing’s air quality was deemed “crazy bad” by the Embassy when the pollution exceeded the bounds of the EPA’s air quality index. This inadvertently undiplomatic tweet reached a growing audience via third-party apps that circumvented China’s twitter firewall. People were attracted by the reliability of the Embassy’s data, which helped them make daily decisions—whether it was safe to let their children play outside, for example.

This data often painted a bleaker picture than did the Chinese official pronouncements. Beijing residents, dissatisfied with the crudeness of China’s air quality monitoring efforts, put pressure on Chinese officials to acknowledge the scale of the problem and start taking proactive measures to tackle it.

I was living in Beijing at the time and followed this Twitter feed right away (although there were many days I wished I hadn’t). We knew the smog was bad (we could see it and taste it), but now we knew just how bad!

I remember the day a tweet declared the pollution in Beijing to be “crazy bad,” and the subsequent temper tantrum thrown by the Chinese government. As the article notes, they demanded the embassy stop monitoring and publishing the air quality measurements, to no avail. They even threatened to do monitor and publish information on the air quality in Washington in retaliation, to which the embassy responded, in effect, “go ahead, make my day.”

With the publication of this data, the jig was up for the Chinese government. No longer could they tell the people that the murky air was just fog.

It wasn’t long after all this that Twitter was blocked in China.

 

Two Things I Don’t Miss

Two months ago today I flew out of Beijing to begin a longish stint back in the US of A. For a variety of reasons, both personal and professional, I will be based in the US and travel often to China, instead of the other way around — as has been the case for the past 4 years.

I miss Beijing and my friends there A LOT, but following the news out of China last week reminded me of a couple of things that I don’t miss: the pollution and trying to get a taxi.

Beijing’s ‘Airpocalypse’ Spurs Pollution Controls, Public Pressure (NPR)

 

Chinese air pollution hits record levels — in pictures  (The Guardian)

One of my favorite websites, Tea Leaf Nation, did a story on the difficulty of hailing a cab in Beijing, particularly during rush hour in a piece titled “At Rush Hour in Beijing, Riders Beg, and Many Taxi Drivers Say “No.” 

This problem had gotten so bad in my neighborhood that it was impossible to get a taxi between 7 and 9AM or between 5 and 7PM. Whenever someone would suggest an appointment at 8 or 9AM my heart would sink because I knew I would have to leave at 630 or 645 if I had any chance of getting out of my neighborhood. And sometimes, even if they were empty cabs on the roads, the drivers would just wave as they drove by.

Two things I really don’t miss….

Reading Assignment — Bathed in Smog (Again)

I realize that you may be getting tired of reading posts about the smog here in Beijing, but it is really…pardon the pun….the air we breathe.

I think that this has to be the most depressing headline ever: Bathed in Smog: Beijing’s Pollution Could Cut Five Years off Lifespan, Experts Say. (NBC)

This story, written by Adrienne Mong, focuses on the economic and health effects of our smog and the growing increasingly political nature of measuring air quality in Beijing. You see, the US Embassy monitors air quality in the capital and publishers their readings hourly on Twitter. It almost always hovers between “unhealthy” and “hazardous.” Sometimes it literally goes off the chart and the Twitter feed labels it “crazy bad,” at which point the Chinese government gets crazy mad and the laobaixing (common people) get crazy sad. Some have even speculated that this is what triggered the blocking of Twitter in China.Who knows?

Anyway, here are some of the key graphs from the article:

Earlier this month, a U.S. study on the economic impact of China’s air pollution was released with little fanfare. Maybe it was because of the series of successive “blue sky” days we were enjoying in the Chinese capital, thanks to the gusty winds blowing down from Mongolia. 

The study, which was conducted by researchers at the MIT Joint Program on the Science and Policy of Global Change, breaks down costs that result from the health impacts from ozone and particulate matter, which typically lead to respiratory and cardiovascular diseases.

The conclusion? “[D]espite improvements in overall air quality,” the cost of air pollution (as in lost economic productivity growth) in China has mushroomed from $22 billion in 1975 to $112 billion in 1995. But for at least one pair of 29-year old software engineers in Beijing, air pollution has actually meant greater economic productivity and a business opportunity.

Mong then goes on to write about the battle discrepancy between the US embassy and Chinese government readings (illustrated in the picture above):

The readings come from an air quality monitor that sits on top of the embassy in downtown Beijing, and they differ sharply from the daily results posted by the Ministry of Environmental Protection (MEP).

AQI values on @BeijingAir range from 0 to 500.  A “good” AQI  is 0 to 50 or what the Chinese call a “blue sky” day.  Unfortunately, many days in 2011 qualified as “unhealthy” to “hazardous.”  But on some of those same days, MEP data maintained the levels were “good” or “moderate.”  (The Chinese, in fact, claim there were 286 “blue sky” days in 2011.)

“The [Beijing] government says that nearly 80 per cent of the days in the last two years met at least the Chinese standard and therefore had good or even excellent air quality,” Steve Andrews, an environmental consultant who has analyzed the @BeijingAir data, said. “While when we look at the U.S. embassy data … over 80 per cent days exceeded what would be considered healthy air quality and more days were hazardous than good.”

Andrews said that Beijing’s pollution levels were “six or seven times higher than the U.S.’s most polluted city.” “Air pollution at these levels likely shortens life expectancy by about five years,” he added.

Who are you going to believe? The government or your burning eyes? I’m going with the eyes.

Read and discuss among yourselves.

Smog Alert

Even though I am in Minnesota, enjoying the delights of clean air AND snow, I thought I’d join the stampede to rant about the terrible smog that has enveloped Beijing.

 

Obviously I can’t give a first-hand account, so I’ll share with you this description of what it’s like in Beijing today.  It’s a post titled “Holding Our Breath” on the blog Absurdity, Allegory, and China:

 

The days between then and now have not been all that different: a few ‘Good’ and ‘Moderate’ periods, though mostly ‘Unhealthy’ and above. The exception has been the period we are in at the moment. As I write the PM 2.5 readings have been pegged in the ‘Hazardous’ zone since yesterday (Sunday) afternoon, 12-04-2011; 16:00; PM2.5; 406.0; 438; Hazardous, more than 19 hours ago. A few hours after the air quality entered the ‘Hazardous’ zone it reached the unmeasurable range (what some have unofficially deemed “Crazy Bad”) @ 12-04-2011; 19:00; PM2.5; 522.0; 500; Beyond Index , which is somewhat akin to WWI trench warfare air. How far ‘Beyond Index’ was it? There’s no way of knowing that, though if the CN.gov folks do, they aren’t about to tell anyone. In fact I’m surprised they haven’t sniped the measurement machine on top of the U.S. Embassy, yet. They hate it. Recently there have been at least two smartphone applications that republish the hourly U.S. Embassy readings. But despite a rise in requests to come clean with the real information, the Beijing Environmental Protection Bureau has refused to make that data available. {In Chinese}

 

For more see The Ministry of Tofu’s Photos: Smog-shrouded China denies citizens right to know pollutant measurements. Also have a look at this photo taken at the Beijing Capital Airport last night by @kinablog who was on an Air China flight that was grounded due to the heavy smog.

 

My friend Amy, who blogs at The Messy Middle also wrote about the sorry state of Beijing’s air.

 

I love the headline in the China Daily about the problem:  Smog spawns environmental awareness in China. Spinning smog as a good thing?  “Just think, if it weren’t for the smog, we wouldn’t be thinking about environmental issues.”

 

I think mostly people are becoming aware that they are being lied to.

These pictures were posted on the Chinese micro-blogging site Weibo this week.  They were not actually taken this past weekend, but this is pretty much what it looked like here on Sunday. I think that for about the tenth time this year I made the statement “this is the worst smog I’ve ever seen in Beijing.”

 

The BeijingAir Twitter feed from the US Embassy indicated that the air pollution was off the charts.  Literally — the top of the scale is 500, and their numbers topped those. This usually creates a bit of an international incident because the Chinese government’s readings are always about half what the embassy’s readings are. Some think that it is because of this Twitter feed that the Chinese government blocked Twitter in China. They were afraid it would confuse the people and disturb social stablity.

 

I don’t think folks here are confused.  Who are you going to believe? The government or your dying lungs?

 

 

 

The Smog! The Smog!

Besides the snow and the heat coming on early, the other big story in town this week is the smog.  I realize that I say this about every six months or so, but I think yesterday was as bad as I’ve even seen it in Beijing. Within minutes of stepping outside my eyes were burning and I had a headache and felt sick to my stomach.

Yesterday a NASA satellite took an amazing photo of north China showing the extent of the smog.

I’m posting it here in case you think I’m exaggerating.


Now excuse me while I figure out a way to strap my air purifier onto my face.
