The Nature Causes

Sun spots

Water vapor

Climate Cycle

LOGO


Sunspots

The sunspots will have an intense influence on magnetic activity.

LOGO


Water

Water vapor: the gas shape of water, which play an important role in global warming.Water vapor absorbs and emits the radiation to the atmosphere, thereby increasing the temperature.(Dr.S.Fred.2001)

LOGO


Climate Cycle

The regular climate change cycles, which occur over a period of approximately 40,000 years.Nowadays, the earth turn to the warming cycle naturally(National Graphic).

The Man-Made Causes

Fossil fuels

Methane

Deforestation

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.
