China’s capital woke up to orange-tinted skies Saturday as the strongest sandstorm so far this year hit the country’s north, delaying some flights at Beijing’s airport and prompting a dust warning for Seoul.
The sky glowed and a thin film of sand covered Beijing, causing workers to muffle their faces in vast Tiananmen Square.
The city’s weather bureau gave the air quality a rare hazardous ranking.
Air quality is “very bad for the health,” China’s national weather bureau warned. It said people should cover their mouths when outside and keep doors and windows closed.
China’s expanding deserts now cover one-third of the country as a result of overgrazing, deforestation, urban sprawl and drought. The shifting sands have led to a sharp increase in sandstorms, the grit from which can travel as far as the western US.
The Chinese Academy of Sciences has estimated that the number of sandstorms has jumped six-fold in the past 50 years to around two dozen a year.
The latest sandstorm has also affected the regions of Xinjiang and Inner Mongolia and the provinces of Shanxi, Shaanxi and Hebei.
As the sandstorm moved southeast, South Korea’s national weather agency issued a yellow dust advisory for Seoul and other parts of the country. Chun Youngsin, a researcher at the Korea Meteorological Administration, said the yellow dust was expected to hit the Korean peninsula beginning yesterday afternoon and it would be “the worst yellow dust” this year.
Some flights at Beijing’s international airport were delayed but eventually took off, said a woman answering inquiries from concerned passengers on the airport hot line.
China has planted thousands of acres of vegetation in recent years in an effort to stop the spread of deserts in its north and west, but experts have said the work will take decades. China’s dust storms were at their worst in the 1950s and 1960s after campaigns to raise farm and factory output following the 1949 communist revolution stripped the soil of vegetation.
“I think this kind of natural disaster is caused by human activity, but I don’t know the exact reason, and I don’t know exactly what we can do to prevent this,” Shi Chunyan, a Beijing resident, said of yesterday’s storm.
Australian scientists have raised questions over the efficacy of the AstraZeneca and University of Oxford COVID-19 vaccine in establishing herd immunity, calling for a pause on its widespread rollout as the country recorded one new case of the virus yesterday. Opposition to the vaccine casts a cloud over Australia’s immunization plans, with 53 million doses of the AstraZeneca jab already on hand. “The question is really whether it is able to provide herd immunity. We are playing a long game here. We don’t know how long that will take,” Australian and New Zealand Society for Immunology president Stephen Turner said. Turner added
A racing pigeon has survived an extraordinary 13,000km Pacific Ocean crossing from the US to find a new home in Australia. Now authorities consider the bird a quarantine risk and plan to kill it. Kevin Celli-Bird yesterday said he discovered that the exhausted bird that arrived in his Melbourne backyard on Dec. 26 last year had disappeared from a race in the US state of Oregon on Oct. 29. Experts suspect the pigeon that Celli-Bird has named Joe — after US president-elect Joe Biden — hitched a ride on a cargo ship to cross the Pacific. Joe’s feat has attracted the attention
China has possibly committed “genocide” in its treatment of Uighurs and other minority Muslims in its western region of Xinjiang, the US Congressional-Executive Commission on China said in a report on Thursday. The bipartisan commission said that new evidence had last year emerged that “crimes against humanity — and possibly genocide — are occurring” in Xinjiang. It also accused China of harassing Uighurs in the US. China has been widely condemned for setting up complexes in Xinjiang that it describes as “vocational training centers” to stamp out extremism and give people new skills, which others have called concentration camps. The UN says that
The Polish Supreme Court on Friday quashed a lower court’s green light for the extradition of a businessman to China for alleged fraud, a charge he has denied, saying that he is being targeted for supporting Falun Gong. Polish authorities took Chinese-born Swedish citizen Li Zhihui, now 53, into custody in 2019 on an international warrant issued by China for alleged non-payment in a business deal, Krzysztof Kitajgrodzki, his Polish lawyer, told reporters. Following the Supreme Court ruling, the case would return to a lower appellate court for review. Kitajgrodzki told reporters that it was still not a given that his client
