Global warm­ing caus­ing more deadly air pol­lu­tion peaks

New Straits Times - - World -

PARIS — about 40 times thin­ner than a hu­man hair.

The burn­ing of coal, along with ve­hi­cle emis­sions and dust, are the main sources of th­ese ul­tra­fine specks, which can cause se­vere res­pi­ra­tory prob­lems and in­crease the risk of heart dis­ease.

Small enough to en­ter hu­man cells, they can also af­fect the im­mune and ner­vous sys­tems.

In ma­jor cities across north­ern China, the num­ber of days with “se­vere haze” jumped from 12 to 18 to 25 dur­ing the win­ters of 2014, 2015 and last year, re­spec­tively.

In Jan­uary, a thick blan­ket of sun-dim­ming haze set­tled over the Bei­jing-Tian­jin basin — home to more than 100 mil­lion peo­ple — for eight con­sec­u­tive days, caus­ing tens of thou­sands to flee cities and vent their anger on so­cial net­works such as Weibo and WeChat.

For sev­eral days run­ning, the to take eight years and is part of the is­land’s “in­dige­nous de­fence pol­icy”, said Tsai.

“I want to tell you all that the Tai­wanese al­ways face chal­lenges bravely and over­come them.” den­sity of par­ti­cles 2.5 mi­crons or smaller was higher than 500 mi­cro­grammes per cu­bic me­tre, more than three times the dan­ger thresh­old set by the World Health Or­gan­i­sa­tion.

“I would rank air pol­lu­tion as the num­ber one or num­ber two con­cern for or­di­nary peo­ple in north­ern cities in China,” co-au­thor Hong Liao, a re­searcher at Nan­jing Univer­sity’s School of En­vi­ron­men­tal Science and Engi­neer­ing, said. AFP

De­fence Min­is­ter Feng Shihkuan had said Liaon­ing’s naval drill near Tai­wan high­lighted the need for the is­land to press ahead with build­ing its own sub­marines. AFP
