Why is the weather always like this?

There are two theories now. One is global warming. Because of large-scale deforestation due to human activities. Causes global greenhouse effect. The greenhouse effect effectively prevents the Earth from reflecting the sun's rays. It is a high temperature that is common around the world. The other is solar flare activity. In recent years, global warming has been caused by unprecedented activity in the center of the sun, which lasts for ten years. At that time, ocean activity will calm down, and the global climate will return to the time when there were four seasons.
