Global warming continues. Why is it colder in northern China than in previous years?

First of all, we should know that global warming is the most familiar professional term in climate change.

It's getting colder and colder. Global warming has little to do with climate change. This is just extreme weather under climate change. Some places are getting colder and colder, some places have less and less rainfall, and some places are more waterlogged and may be drier.

Global warming, warming in the Arctic and Antarctic lead to the melting of glaciers. Here, I want to mention the Arctic amplification effect. Arctic glaciers melt, exposing seawater. Because seawater is darker than glaciers and absorbs more solar radiation, the Arctic is accelerating warming. Arctic warming reduces the temperature difference between high latitude and low latitude, and weakens the mid-latitude westerly wind, thus weakening the warm current of the North Atlantic brought by the mid-latitude westerly wind.

Latitude is similar to that of western Europe in the northeast of China, but the coldest monthly average temperature in high latitudes exceeds zero, which is because the North Atlantic warm current provides heat for it. When the North Atlantic warm current weakens and the warming weakens, the average temperature in western Europe also decreases, and it turns cold under the trend of global warming.

Global warming and melting glaciers have led to an increase in precipitation in some areas and a large increase in fresh water in sea areas, which in turn affects ocean currents and ocean currents affect climate. If it is unrealistic to expect global warming to make winter warm, it is more likely to make winter cold in China.

It is also said that there was a very warm period in the history of the earth, even higher than the current temperature. The water temperature in the western Pacific warm pool once reached 33℃ (the highest is about 29℃ now), and there was no extinction disaster. The reason may be that the process of climate warming is slow, and organisms have enough time to adapt. At present, the process of global warming is very fast, coupled with the rapid advancement of urbanization, the rapid development of industry, the over-exploitation and utilization of resources, the pressure on the natural environment is enormous, and the contradiction between man and land needs to be coordinated urgently.

The warm climate in the past does not mean that we can't take preventive measures now. Climate change is closely related to everyone, so we should start with small things and protect our common home.
