It's cool, but it's actually very cold.

There is a saying that the heat is balanced, although there is a gradual "warming" phenomenon. Therefore, cool summer should be accompanied by warm winter. However, it is hard to say that climate prediction has been able to accurately predict for nearly three days, but it is still difficult to predict. In addition, I think spring, summer, autumn and winter are still very clear, but extreme weather is becoming more and more frequent. For example, the temperature suddenly changes for a day or two, or a snowstorm or rainstorm returns to normal for a day or two. Overall warming is an indisputable fact. I am in my thirties. When I was a child, I could hardly see the ice cone under the eaves. Although the building structure has improved, I obviously feel much colder when I was a child, don't you think?
