Summary
In conclusion, Global warming is caused by the combination between natural and human activities. The natural reason contains the sun spots exploding, Water vapor, and Climate cycles. And the Burning fossil fuels, Methane and Deforestation can be considered as the man-made reason. All of the factors are contributed to the effect of temperature increasing, sea level rise and the animal migration, which will have an negative on the development of human.
