‘Airpocalypse’ In China

Beijing: Beijing is the third most polluted major city on Earth on Wednesday, just ahead of Bangladesh’s capital, Dhaka, stated IQAir– air quality monitoring firm.

With tens of millions of people in northern China under severe pollution warnings, a thick haze has this week smothered Beijing and surrounding areas.

Many of Beijing’s 22 million residents donned face masks on Wednesday morning as they snaked through streets shrouded in a gray haze.

Foggy and hazy conditions are prevalent in the capital Beijing, the megacity of Tianjin, and parts of the provinces of Hebei, Shandong and Hubei, home to more than 100 million people in total, stated China’s weather office.

The pollution in some areas has been classified as “severe” and has at times lowered visibility to less than 50 meters (164 feet).

IQAir data revealed that Beijing has experienced five days with unhealthy pollution levels in the last week, compared to just three such days in the past three weeks.

Beijing’s concentrations of hazardous PM 2.5 particles are more than 20 times higher than World Health Organization guidelines, the firm said.

According to the US Environmental Protection Agency, PM 2.5 particles, if inhaled, can have serious health risks linked to premature deaths in people with heart or lung disease, as well as a host of breathing and other health issues.

Is the situation getting better?

A decade ago, Beijing routinely choked in off-the-charts smog that stoked public health anxiety and was dubbed the “airpocalypse” by Western commentators.

China declared a “war on pollution” after winning the Winter Olympics bid in 2015, shutting down dozens of coal plants and relocating heavy industries.

That has brought significant improvements but air quality often remains below World Health Organization standards, and severe pollution is common in China’s capital.

Data from the US Embassy showed that in March and April, Beijing experienced six days when pollution levels were considered “very unhealthy”, meaning air quality had reached emergency levels. Beijing also experienced five days of “unhealthy” pollution levels around October and November last year.

China is the world’s biggest emitter of the greenhouse gases driving climate change, such as carbon dioxide.

A recent jump in approvals for coal-fired power plants has added to concerns that China will backtrack on its goals to peak emissions between 2026 and 2030 and become carbon-neutral by 2060.

The capital’s location plays a role. Nestled between deserts to the north and dense industrial clusters to the south and east, the direction of the prevailing wind can often determine whether the city sees blue skies or dense smog.

But the bad air is also man-made: highly polluting heavy industry, the common use of coal burning for electricity and vehicle emissions, IQAir said.

Beijing’s city government has blamed “unfavourable weather conditions” such as high humidity and unseasonably hot temperatures. It has said that colder weather may help dissipate the pollution.

The second-highest air pollution alert is in place in Beijing until the end of Thursday. The alert orders businesses, builders and transport firms to cut their emissions as a matter of urgency.

Further curbs, such as temporary bans on the use of some high-emission vehicles, will come into force if the highest alert—already in force in parts of Hebei province—is triggered.

Authorities have also urged residents to reduce outdoor activities and strenuous exercise during periods of high pollution.
