世界氣象組織發布報告指出,氣候變遷導致熱浪與野火頻發,產生大量PM2.5等微小污染物。儘管工業排放法規有所成效,但野火帶來的毒性濃煙正抵銷空氣品質改善成果,對人類健康與生態系統構成嚴重威脅。

世界氣象組織發布年度空氣品質與氣候公報,強調氣候變遷與空氣污染之間的惡性循環。極端天氣事件如野火正成為PM2.5污染的主要來源之一。
(中央社日內瓦7日綜合外電報導)世界氣象組織(WMO)今天表示,野火與熱浪會產生微小空氣污染物,恐將削弱國際間改善空氣品質、保護人類健康及維護大自然所做的努力。
法新社報導,世界氣象組織強調空氣污染與氣候變遷之間的關聯,科學家指出,氣候變遷正導致熱浪與野火變得更加頻繁且劇烈。
世界氣象組織今天發布最新年度「空氣品質與氣候公報」(Air Quality and Climate Bulletin),同時發表一份聲明指出:「極端野火正持續增加,且由於濃煙具高度毒性,進而帶來巨大的健康後果。」
聲明並指出:「雖然歐洲和北美洲的法規已減少工業和交通排放的PM2.5,但暴露於野火相關PM2.5的情況卻有所增加。」
懸浮微粒PM2.5是由直徑小於2.5微米的微小顆粒和液滴組成,由於能深入肺部和血液中,因此對健康構成危害。PM2.5由化石燃料驅動的工業活動、農業、家用暖氣和交通運輸所排放,也會透過野火和沙塵暴產生。
報告指出,全球需要更好地監測包含黑碳和塑膠微粒的氣膠、細懸浮微粒以及地表臭氧等空氣污染物。
世界氣象組織表示,這些污染物「儘管分布廣泛且可能對生態系統有害,卻未得到充分的監測」。

The youth team of the Shandong Provincial Geological and Mineral Engineering Survey Institute went to Xinxing City, the 13th Division of the Xinjiang Production and Construction Corps, to carry out the ecological restoration project of the abandoned mines in the East Tianshan Mountains. The team overcame extreme climate and environmental challenges, achieved ecological management of the Gobi Desert through scientific and technological solutions, and promoted Shandong-Xinjiang geotechnical collaboration and talent cultivation.

The Malaysian government announced the lifting of the haze emergency in Serian, Sarawak, but due to the impact of Indonesian forest fires, the local air pollution index is still at a very unhealthy level. The authorities called on the public to reduce outdoor activities and continue to monitor air quality.

Category 3 Hurricane Loire is approaching Hawaii, and hurricane watches have been issued for Kauai and Niihau islands. The hurricane is expected to pass west of Hawaii late Monday night, bringing heavy rainfall. There are currently three storms in the Pacific Ocean at the same time. Affected by the El Niño phenomenon, the sea water temperature has increased.

Category 3 Hurricane Loire is approaching the U.S. Pacific Islands. The U.S. National Hurricane Center has issued a hurricane watch for Kauai and Niihau Islands in Hawaii. It is expected to bring up to 14 inches of rain.

Malaysia activated a local emergency in Sarawak after air pollution in Serian surpassed the critical threshold of 500 due to severe haze, prompting health warnings and monitoring by federal and state governments.

Climate warming is exacerbating extreme weather, thunderstorms, clear-air turbulence and rising sea levels around the world, posing a serious threat to busy airspace and airports in the UK and Europe. Aviation experts warn that this will increase flight delays, cancellations and fuel costs, and may pose hidden risks to aviation safety.
