太平洋幾乎覆蓋了地球表面的三分之一。上千個島嶼散布在這片海洋上。近年來，這些島嶼上的人們注意到潮水越來越高，暴風(fēng)雨越來越嚴(yán)重。他們想知道——他們的世界即將改變嗎？不幸的是，事實(shí)上太平洋上的島嶼，特別是低洼的珊瑚島，正在遭受全球變暖的嚴(yán)重影響。

LanguagePoints

隨著全球氣溫升高，海平面也在上升。氣溫上升導(dǎo)致北極和南極的冰蓋和冰川融化，向海洋注入更多的水。相比，溫暖的海水，較冷的海水還會占據(jù)更多的空間，因此隨著海洋變暖，海平面會進(jìn)一步上升。科學(xué)家預(yù)計(jì)，如果地球繼續(xù)變暖，到2100年，全球海平面可能會上升0.6米至1.3米或更高。在太平洋島嶼上，海平面上升最明顯的跡象是，在漲潮時海水涌入更多內(nèi)陸地區(qū)，流入房屋，漫過道路。事實(shí)上，海灘甚至整個島嶼正在消失：自1947年以來，所羅門群島中已有五個島嶼消失在海浪之下！不斷上升的海平面還污染了島嶼的淡水供應(yīng)。當(dāng)含鹽的海水滲入地下、進(jìn)入水井時，其中的水就無法用于飲用和灌溉。此外，不斷上升的海平面還會干擾島嶼的自然重塑過程。通常，海浪逐漸將沙子從島嶼的一側(cè)帶走，并將新的沙子堆在另外一側(cè)。但不幸的是，不斷上升的海浪加速了這一過程，這無疑會給生活在沙子被沖走一側(cè)的人們帶來問題。

助力教與學(xué)

與此同時，不斷上升的全球氣溫還有著了其他方面的毀滅性后果。極端氣溫會產(chǎn)生極端降雨模式。結(jié)果是，這些島嶼幾個月都沒有能讓生命得以維持的降雨，導(dǎo)致農(nóng)作物歉收，淡水儲備減少。然后突然一下子來了太多的雨水，寶貴的土壤和家園被洪水沖走。例如，在多山的庫克群島，暴風(fēng)雨導(dǎo)致山體滑坡，島上居民的房屋被沖下山坡。此外，每年的熱帶氣旋變得越來越強(qiáng)，發(fā)生頻率也越來越高，導(dǎo)致更嚴(yán)重的洪水和山體滑坡。更重要的是，隨著海洋變暖，許多珊瑚礁正在死亡，它們本來是天然的安全屏障，是各種各樣的海洋生物棲息的家園。高溫和大氣中的二氧化碳會對構(gòu)建珊瑚礁的珊瑚蟲產(chǎn)生不利影響。沒有健康的珊瑚礁，魚類就會離開，島民的食物就會減少。

盡管面臨挑戰(zhàn)，島上居民并沒有不戰(zhàn)而降。對許多島上的社區(qū)來說，應(yīng)對氣候變化不是一件可以選擇做或不做的事情，而是一個關(guān)乎到生存的問題。他們正在與科學(xué)家合作，學(xué)習(xí)如何利用舊的珊瑚礁碎片建造海堤，以保護(hù)他們的家園免受洪水和風(fēng)暴潮的侵襲。他們減少砍伐樹木，因?yàn)闃淠灸鼙３滞寥?。他們還種植紅樹林來保護(hù)沿海地區(qū)。為了讓有害鹽分遠(yuǎn)離他們的作物，他們在容器中種植作物。他們正在尋找可以適應(yīng)含鹽量較高的水的作物。希望他們能找到留在島上的辦法，哪怕只是多留一段時間。However,someislandershavemadealife-changingdecision--movingawayfromtheocean.Itisbynomeanseasyastheoceanhasbeenpartoftheirliv
