不幸的是，從過去幾個很熱的夏天中總結(jié)經(jīng)驗，我們似乎發(fā)現(xiàn)，每個極熱的夏天背后都跟著一個極冷的冬天。為防范這些損失又需要花巨資升級城市基礎(chǔ)設(shè)施，這些都是成本。而對于城市居民來說，“天氣災(zāi)難”可能意味著出行或不得不呆在家里的不便，對于農(nóng)業(yè)生產(chǎn)來說，這可能意味著實際損失。陳說，這被稱為“北極增暖放大”現(xiàn)象，這一過程已經(jīng)開始，在人類停止全球變暖活動之前不會逆轉(zhuǎn)。Mini-projectGuangzhou,aGatewaytoMaritimeSilkRoadTheEarthisUnderEcologicalThreatsLesson1?

Twoweekspassed.theyranoutofmoney.兩星期過去，他們的錢用光了。Words&ExpressionsLesson1Guangzhou,aGatewaytoMaritimeSilkRoadReadingTheEarthisUnderEcologicalThreatsLesson1極端天氣來襲①極端”可以說是2023年夏天的第一關(guān)鍵詞。我們有過平均氣溫22°C，是除1961年外最高溫度的記錄。不幸的是，過去的經(jīng)驗歲月表明，在每一個極度炎熱的夏天之后隨之而來的是一個極度寒冷的冬天。②極端天氣就好比單擺，如果擺錘在一端擺幅已經(jīng)很大，那在另一端也可能會很大，因為整個單擺的閾值已經(jīng)提高了。但在擺錘沒有擺到另一邊之前，誰也沒法給出肯定的答案。③陳衛(wèi)博士給出了進一步的解釋。地球是赤道熱兩極冷，氣流自然會從熱帶亞熱帶的高壓地區(qū)往極地低壓地區(qū)流動。受地轉(zhuǎn)偏向力的作用，這一氣流在北半球中緯度向右偏轉(zhuǎn)為西風。正常情況下，極地的“冷”與赤道的“暖”之間存在明顯的南北溫度梯度，這使得西風帶很強盛，存在于其中的環(huán)流也很穩(wěn)定，起到阻擋北極冷空氣南下的重任。Lesson1Guangzhou,aGatewaytoMaritimeSilkRoadReadingTheEarthisUnderEcologicalThreatsLesson1④但隨著全球變暖加劇，北極增暖更為明顯，與赤道間的溫度梯度減弱，導(dǎo)致西風帶減弱，極地渦旋變得不穩(wěn)定，極渦內(nèi)的冷空氣分裂南下，寒潮就能大舉南侵。所以，雖然全球溫度在升高，我們冬天感受到的寒潮反而更強。全球變暖與極冷天氣不沖突，緣由在此。⑤更可怕的還在后邊。結(jié)滿了冰的北極本來像面大鏡子，能把照射來的絕大部分太陽光線反射回太空，但隨著海冰融化鏡子越來越弱，反照率越來越低，于是融化的更快，導(dǎo)致北極以兩倍于其他地區(qū)的速度增暖，稱之為“北極增暖放大”現(xiàn)象，這一惡性循環(huán)一旦開啟情況只會越來越壞。在全球變暖趨勢被逆轉(zhuǎn)之前，這一情況只會越來越明顯。Lesson1Guangzhou,aGatewaytoMaritimeSilkRoadReadingTheEarthisUnderEcologicalThreatsLesson1⑥對于城市居民來說，氣候災(zāi)難可能意味著忽冷忽熱的氣溫、意味著街道上的積水、意味著下大雨無法出門而遲到被扣錢。但對農(nóng)業(yè)生產(chǎn)來說，氣候災(zāi)難給人的感受可能更深。在極端天氣下，一些戶外建筑或工程項目不得不暫?；蛎媾R低效率的窘境。農(nóng)作物可能在極寒中枯萎或在高溫下死亡，從而對國家糧食安全構(gòu)成更大的挑戰(zhàn)。城市要么面臨洪水的損失，要么提高建筑物的標準以抵御這種洪水，這兩者都需要花錢。⑦酷暑、嚴寒、旱死、內(nèi)澇、海冰融化、大河干涸，這些問題有的開始顯現(xiàn)，有的已經(jīng)很嚴重了，而這一切都是近幾百年來碳排放的累積效應(yīng)。⑧“氣候極端化的進程是非線性的，大自然不會給人類留下太多的時間去適應(yīng)。”2023年夏天，僅在北京就有29.7天氣溫超過35攝氏度，比往年平均數(shù)直接多出21.1天，且有5天超過40攝氏度，是非常危險的信號。留給人類的時間不多了。Lesson2
