I definitely disagree with the people who don't take the responsibility to solve the problem of global warming. I think that Each kind of human activities on the earth contributes to the global warming. If people don't take this problem seriously, the trend of temperature will persistently increase at an accelerated rate.
Green house effect causes global warming directly. Thermal radiation absorbed by the earth face transmit to atmospheric green house gases. The layer of greenhouse gas reflects the radiation in all direction. Since part of re-radiation is back towards the surface and the lower atmosphere, it results in the rising of the average surface temperature.
But where are the greenhouse gas coming from? The answer is ourselves. Human activities including Transportation, waste disposal, biomass burning,Industrial processes are releasing a huge amount of Carbon dioxide, Methane and Nitrous Oxide to the air. Those air pollution form the greenhouse gas layer.
The consequences of a warming world are more serious than what we think. The temperature will increase to a certain degree that human can not bear. Weather Patterns will also change. Fire, drought and lightning will spread out all over the world. Global warming also melts ices in the pole area and rises sea level.
