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 droughts and floods, tropical would be extremely hot, human difficult to survive. Second, the melting polar ice, a large area, so that sea level rise, which will live in coastal areas of the world's 1 / 3 of the population homeless, many of the world port city submerged in a sea of.
