Global Warming

The greenhouse effect, also known as "greenhouse effect" is commonly known as atmospheric thermal effects. Atmospheric short-wave solar radiation can reach the ground, but the outward surface long-wave heat radiation emitted been atmospheric absorption, thus making the surface and lower atmosphere temperatures, similar to cultivated crops because of their role in the greenhouse, hence the name greenhouse effect. If the atmosphere there is no such effect, then the surface temperature will drop by about 330C or more. On the contrary, if the greenhouse effect continuously strengthened, the global temperature will continue to increase year by year. Since the industrial revolution, humans into the atmosphere of carbon dioxide and other heat-absorbing greenhouse gases every year with strong increase in atmospheric greenhouse effect also increases, and has caused global warming, a series of serious problems, caused around the world attention.
And we can fix it by increasing energy efficiency, decreasing the use of fossil fuels and increasing the use of natural energy like solar power, wind power, etc.
