全球气温变暖的主要原因:
人类活动对气候变化肯定是有变化和影响的。
人类燃烧煤、油、天然气和树木,产生大量二氧化碳和甲烷进入大气层后使地球升温,大气中二氧化碳排放量增加是造成地球气候变暖的根源。
The main reason for global warming:
human activities definitely have an impact on climate change. Human burns coal, oil, natural gas which produced a large amount of carbon dioxide and methane, and it warmed the earth. The cause of global warming is the increased carbon dioxide emissions into the atmosphere.
造 成的危害:
首先是自然生态会发生变化;土地荒漠化,森林退向极地,雨量增加,冬天更湿,夏天更旱,旱涝灾害增加,热带将酷热无比,人类难以生存。
其次是两极冰块大面积熔化,使海平面上升,那将使生活在沿海的占世界 1/3的人口无家可归,世界许多港口城市 淹没于一片汪洋之中。
Harms:
first, to change the natural ecology; land desertification, forest back to the polar regions, increased rainfall in winter, wetter, more droughts in summer, increased d
