    人教版高中地理必修1全球氣候變化教案

    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。轉折:既然全球變暖會引起很多不利影響,那么作為人類應如何面對這一挑戰(zhàn)呢?這就是我們要討論的第三個問題。板書:三、氣候變化的適應對策討論:請大家閱讀結合教材P53氣候變化的適應對策部分討論人類應如何面對全球變暖這一問題 呢?
