Why are there more and more weather disasters now?

First of all, you have to understand the three factors that form the climate: radiation, geography and atmospheric circulation.

In fact, there have been many natural disasters. Now, with the development of information technology, people can know the content of the time period in which information occurred at the first time. As for the increasingly extreme climate, there are more than one reason.

I. Human activities

Since mankind entered the industrial age, the environment of the earth has become worse and worse. The over-exploitation of nature leads to the imbalance of natural ecosystem, and all kinds of creatures are extinct due to human activities and cannot be restored to their previous state; The over-exploitation of the ocean and the influence of global climate change have changed the direction and temperature of ocean currents; The increase of greenhouse gases such as carbon dioxide and the destruction of surface vegetation directly lead to the appearance of extreme climate.

Second, solar activity.

The solar activity cycle is 1 1 year, and the earth's climate is strongly influenced by solar radiation. At present, solar flare activities and solar storms are frequent, and the stronger the radiation, the greater the impact on the earth's climate.

Third, the periodic activities of the earth itself.
