Smog, sandstorm turns Beijing yellow

BEIJING: Beijing was cloaked in thick yellow smog on Monday with pollution levels surging off the charts as the worst sandstorm in a decade descended on China´s capital from the Gobi desert. City residents used goggles, masks and hairnets to protect themselves from the choking dust and sand, with landmarks including the Forbidden City partly obscured behind an apocalyptic-looking haze. The city government ordered schools to cancel outside sport and events and advised the public to stay inside where possible, as hundreds of flights were cancelled. Chinese weather agencies blamed the poor air quality on a sandstorm sweeping across northern China from northern Mongolia, where authorities there said it had left several dead, before being carried south by winds and reducing visibility in Beijing to less than 500 metres. Under heavy skies, which draped buildings in an eerie glow, Beijing residents fretted over the health risks of a storm which compounded days of hazardous PM 2.5 pollution in the capital. “I feel every breath will give me lung problems,” Beijing resident Zhang Yunya told media It was the worst sandstorm in a decade to hit a capital, which had pegged its hopes of rebuilding a natural barrier to such phenomena on intensive tree replanting in stripped forest areas, also known as the “green great wall”. Beijing said last year it expected fewer and weaker sandstorms to hit northern China due to its reforestation efforts. A 2019 study published in the journal Nature Sustainability found some two million square miles of vegetation had been added to the surface of the earth since 2000, a quarter of which was contributed by China. But the impact of those greenbelts is disputed against the prevailing desertification of the country´s northwest.
