師：很好。由于存在地球大氣圈、地球水圈和地表的礦物，在地球上這個合適的溫度條件下，形成了適合于生物生存的自然環(huán)境。人們通常所說的生物，是指有生命的物體，包括植物、動物和微生物。據(jù)估計，現(xiàn)有生存的植物約有40萬種，動物約有110多萬種，微生物至少有10多萬種。據(jù)統(tǒng)計，在地質(zhì)歷史上曾生存過的生物約有5億～10億種之多，然而，在地球漫長的演化過程中，絕大部分都已經(jīng)滅絕了。現(xiàn)存的生物生活在巖石圈的上層部分、大氣圈的下層部分和水圈的全部，構(gòu)成了地球上一個獨特的圈層，稱為生物圈。生物圈是太陽系所有行星中僅在地球上存在的一個獨特圈層。課堂小結(jié)：地球所有的外部圈層是相互滲透、相互影響，甚至相互重疊的，在太陽和人類生活的參與下，整個地球生機盎然；同時，它們起著保護地球的作用，可以減弱太陽和宇宙輻射對地表的影響，減少宇宙中的隕石對地球表面的撞擊。外部各圈中的物質(zhì)運動和循環(huán)，是促使地表物質(zhì)和形態(tài)演變的重要動力。

科學家預測，就地區(qū)而言，位于低緯度的大部分國家，農(nóng)作物的產(chǎn)量將減少；而位于高緯度的國家，農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國家位于低緯度地區(qū)，因此，氣候變化的這種區(qū)域差異性，可能會使發(fā)展中國家所面臨的問題更為嚴峻。板書：3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹：全球變暖會影響整個水循環(huán)過程，可能使蒸發(fā)加大，改變區(qū)域降水量和降水分布格局，增加降水極端異常事件的發(fā)生，導致洪澇、干旱災害的頻次和強度增加，以及地表徑流發(fā)生變化。隨著徑流減少，蒸發(fā)增強，全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折：既然全球變暖會引起很多不利影響，那么作為人類應(yīng)如何面對這一挑戰(zhàn)呢？這就是我們要討論的第三個問題。板書：三、氣候變化的適應(yīng)對策討論：請大家閱讀結(jié)合教材P53氣候變化的適應(yīng)對策部分討論人類應(yīng)如何面對全球變暖這一問題 呢？
