〔即時新聞/綜合報導〕在氣候變遷影響下,竟會導致全球有1/3的飛機無法起飛?一份
國外最新公布的研究顯示,在全球暖化更趨嚴重下,將為航空業帶來重大威脅,造成更多
航班延誤或取消。
外媒報導指出,其實早在上月美國西南部就因熱浪侵襲,導致數十架航班延誤或被迫停飛
,當時就是因天氣酷熱、空氣稀薄,導致飛機發動機的性能下降,嚴重影響起飛。
美國研究人員今日公布於「氣候變遷」期刊(Climate Change)的最新研究也指出,暖空
氣會降低飛機機翼產生拉升力的能力,進而導致航空公司必須被迫減少旅客、貨物或燃油
量才能安全起飛;而據研究報告指出,全球暖化導致熱浪侵襲愈來愈頻繁,到了2080年時
機場年度日最高溫可能上升攝氏4到8度,引發更多航班延誤或取消。負重滿載的飛機在一
天溫度最高的時候,必須卸重10%到30%才能起飛。
研究報告指出,數十年後在最熱的日子當中,全球有1/3的飛機可能會因太熱無法起飛,
受影響最深的機場包含跑道較短的紐約拉瓜迪亞機場(LaGuardia),以及阿拉伯聯合大
公國的杜拜國際機場。這樣的現象可能迫使航空業必須為利潤下降做好準備。
3.心得/評論:
原來航空業最大利空...竟然是全球暖化?
還有人覺得全球暖化是假議題嗎?
