The dangers of climate warming is so big

In human history, there is some temperature records: during 1860 ~ 1900, the average temperature of the global land and ocean rose 0. 75℃； Since 1979, the tropospheric temperature rise 0 every ten years. 12 ℃ to 0. 22℃； Since the beginning of the 20th century, the surface of the earth's average temperature has increased about 0. 6℃； In the past 40 years, around the temperature records are often broken. There are many kinds of the factors of climate change. The dramatic increase in population, atmospheric pollution, Marine ecological environment deterioration, land destruction, loss, acid rain forest resources, accelerate the extinction of species and water pollution, toxic waste pollution these think factors, combined with volcanic activity and the change of the earth periodic track these natural factors, or directly or indirectly led to the global warming. The dangers of climate warming, but far beyond our imagination. It can promote the formation of large typhoons, hurricanes, tsunamis and other disasters, may cause secondary disasters, such as debris flow, landslide, etc. ; It can lead to drought, causing food production, direct threat to national stability; It makes melting glaciers, rising sea levels, making the nature food chain fracture gradually; Even can enlarge the popularity of outbreaks, harm to human body health.
