The weather in our country has been extremely severe in the past two years! Does this have anything to do with the construction of the Three Gorges Dam?

1, the weather in China has been abnormal in recent two years? In fact, it is still within the normal range.

2. Human activities certainly have an impact on the environment and climate, but this impact can only be caused by long-term, coordinated and large-scale human activities. One or two ants can do negligible harm to elephants, and so can thousands of ants.

Since the impact of the Three Gorges Dam on the environment is weak on a large scale, what we should see more is the benefits brought by the Three Gorges Dam.

4. At present, there is a consensus on global warming, including two aspects:

First, it is determined by the laws of the universe. (mainly referring to the solar system)

B, greenhouse effect. Since the industrial revolution more than 200 years ago, a large number of human activities have polluted the atmosphere and natural environment. Among them, industrial waste gas has a direct impact, and industrial waste water and other wastes have an indirect impact. These influences are characterized by long-term, same direction and wide range. In addition, the massive destruction of vegetation is also one of the important reasons.

5. The "butterfly effect" expresses the characteristic that everything has universal connection. According to the specific phenomenon, it can only show that there is a connection between the two. As to whether it is a positive influence or a negative influence, we must make a concrete analysis.
