要点二
Metal emissions
Investing in technologies and practices to reduce metal emissions from agriculture, landfills, and natural gas production
要点三
Nitrous oxide emissions
Glacier melting
Glaciers are retreating at an increasing rate, losing mass and shrinking in size This is due to warming temperatures, which is due to ice to melt and glaciers to receive
exacerbation of the greenhouse effect and ultimately causing global warming.
The impact of global warming
Global warming has a wide-ranging impact on natural ecosystems and human society.
Ecosystems are also experiencing shifts in specifications composition, range, and background This can lead to a loss of biodiversity and disrupt ecological balance The loss of specifications and ecosystems has negative implications for human well being and sustainable development

全球变暖global warming
基本介绍
全球气候变暖是一种“自然现象”。由于 人们焚烧化石矿物以生成能量或砍伐森林并将 其焚烧时产生的二氧化碳等多种温室气体，由 于这些温室气体对来自太阳辐射的可见光具有 高度的透过性，而对地球反射出来的长波辐射 具有高度的吸收性，能强烈吸收地面辐射中的 红外线,也就是常说的“温室效应”，导致全 球气候变暖。
过去1000年来全球气温变化示意图
根据仪器记录，相对于1860年至1900年期 间，全球陆地与海洋温度上升了0.75℃。自 1979年，陆地温度上升速度比海洋温度快一倍 （陆地温度上升了0.25℃，而海洋温度上升了 0.13℃）。根据卫星温度探测，对流层的温度 每十年上升0.12℃至0.22℃。
3、气温升高可能 会使南极半岛和 北冰洋的冰雪融 化。北极熊和海 象会渐渐灭绝。
4将感染疾病等传染病病菌 通过极端天气和气候事件 （厄尔尼诺现象，干旱，洪 涝，热浪等） ，扩大疫情 的流行，对人体健康危害。
关于哥本哈根世界气候大会
哥本哈根世界气候大会全称是《联合国气候变化框架 公约》第15次缔约方会议暨《京都议定书》第5次缔约 方会议，这一会议也被称为哥本哈根联合国气候变化 大会，于2009年12月7日—18日在丹麦首都哥本哈根召 开。12月7日起，192个国家的环境部长和其他官员们 在哥本哈根召开联合国气候会议，商讨《京都议定书》 一期承诺到期后的后续方案，就未来应对气候变化的 全球行动签署新的协议。这是继《京都议定书》后又 一具有划时代意义的全球气候协议书，毫无疑问，对 地球今后的气候变化走向产生决定性的影响。这是一 次被喻为“拯救人类的最后一次机会”的会议。会议 在现代化的Bella中心举行，为期两周。

4.What should do
1.Individual efforts 2.National efforts
First, we should use more clean energy and less coal and oil.
Second, we should go to work foot or by bus instead of driving a car if possible.
2.What caused global warming
Natural causes
Greenhouse effect
Human reasons
Human activities-emission
Greenhouse effect
The so-called greenhouse effect is short wave solar radiation through the atmosphere into the ground, and warming the ground after the length of radiation being released in the atmosphere by absorbing carbon dioxide and other substances, thereby creating the effect of atmospheric warming.
Greenhouse effect
Human activities-emission
Burning natural gas, coal, and oil Electricity generation Deforestation Many factories produce long-lasting industrial gases
英语全球变暖PPT
What should governments do?
First, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal.

Our globe is in danger!
The envBiblioteka ronmental problems!!!
Sandstorm Water pollution Deforestation Air pollution Drought Littering Light pollution Desertification Melting polar ice cap
I don’t dare to see! 惨不忍睹！！！！
Littering
I don’t want to say anything !
你懂的！！！！！！！！
IS that our futuer?
It is the natural revenge(报复) that makes flood and tsunami happen frequently.
Sandstorm
AS far as chen guang(陈光)is concerned, the reason why sandstorms strike us so often are as follows: Firstly,to build house and grow more crops,people cut down more and more trees every year. Secondly,large areas of green grass and forests have been destroyed because of the pollution caused by some factories. Thirdly,when plenty of big trees are cut down ,few young trees are planted .Gradually, so many green hills turn into wastland.When rains fell to come,sandstroms strike us. So the best solution for us is action.we must look after the forests and plant more trees right now. Dirty air and poisonous water from factories should be made clean before they are sent into the air or poured into river.
tsunami
flood
What can we do to prevent our globe from being in danger?
In my view,we have the responsibilities to take care of the Earth for ourselves and for our later generation.Not only should we realize these problems ,but also we should take messures to cope with these problems with the help of the government.Althought the laws have been passed to stop pollution ,there is still a long long way to go!
Water pollution
