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.

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

• 地球两极冰雪融化会导致海平面上升，众多 岛屿将被淹没，一些岛国可能不复存在。
Droughts
If the es Celsius, the world will have more than 30 million people water shortages. 如果地球平均气温上升4摄氏度，全 球就会有30多亿人面临缺水问题。
The cause of global warming
1.Natural cause: The green house effect
2.Human reasons: Human activities
The green house effect
The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases. 温室效应是一个过程,从行星表面热辐射被大气吸收温 室气体,并再次辐射向四面八方。因为这部分再辐射回 到地表和低层大气,它导致海拔平均表面温度高于没有 这部分气体。
