2、pollution 全球氣候變暖是一種全球氣候變暖是一種“自然現(xiàn)象自然現(xiàn)象”。人們焚燒。人們焚燒化石礦物以生成能量或砍伐森林并將其焚燒時會產(chǎn)化石礦物以生成能量或砍伐森林并將其焚燒時會產(chǎn)生二氧化碳等多種溫室氣體。這些溫室氣體對來自生二氧化碳等多種溫室氣體。這些溫室氣體對來自太陽輻射的可見光具有高度的透過性，而對地球反太陽輻射的可見光具有高度的透過性，而對地球反射出來的長波輻射具有高度的吸收性，能強(qiáng)烈吸收射出來的長波輻射具有高度的吸收性，能強(qiáng)烈吸收地面輻射中的紅外線，導(dǎo)致全球氣候變暖，也就是地面輻射中的紅外線，導(dǎo)致全球氣候變暖，也就是常說的常說的“溫室效應(yīng)溫室效應(yīng)”。全球變暖會使全球降水量重。全球

3、變暖會使全球降水量重新分配、冰川和凍土消融、海平面上升等，既危害新分配、冰川和凍土消融、海平面上升等，既危害自然生態(tài)系統(tǒng)的平衡，更威脅人類的食物供應(yīng)和居自然生態(tài)系統(tǒng)的平衡，更威脅人類的食物供應(yīng)和居住環(huán)境。住環(huán)境。energy sourcesWe depend on energy to do many things in our daily lives.
