As we all know, there is a big problem on the earth, ‘Globe warming’ . It is related to human’s survival, so we should know the whole system of the earth, then we will understand why the warming will destroy and kill the life.

Glacier ice exists on all the continents except Australia. Mountain glaciers, in particular, are very sensitive indicators of climate change, the glaciers and the ice serve many functions. Firstly, during the Arctic winter, the air is colder than the water, the ice helps to insulate the water from the atmosphere, where there is no ice there’s a huge heat flow from the water to the atmosphere, which causes the air temperature to go up; Secondly, the ice also restricts the energy of the wind from causing waves near the ice, that’s why ships often stay near the ice, where the seas are calmer; Thirdly, the ice also acts as a mass exchange preventing ocean water from evaporating into the atmosphere, and since ice is white, it reflects the sun’s energy and keeps the system cool, without ice, the temperature of the earth would be likely to increase, perhaps significantly. Even a modest of 2 to 4 degrees, Fahrenheit could have a profound effect, some regions of the world might experience more rainfall which leads to floods, which would have impact on agriculture and forest growth. Fertile wet lands could be lost due to rises in sea level, and low-lying areas might experience flooding from melting water run off, higher temperatures in most areas of the world could become fertile breeding grounds. So, we
