According to scientists' observation, the global climate is getting warmer. What are the main reasons for climate warming?

There have been many species extinctions in the history of the earth for many reasons. The earth is the home where human beings live. Whether human beings can survive and reproduce on the earth for a long time has a great relationship with the earth environment.

It is believed that the massive emission of carbon dioxide has caused climate warming and caused a lot of harm. Some we can really feel. The real killer of global warming is it, not carbon dioxide.

Cold wave and climate warming seem to be opposites, but they are not contradictory. Unlike a simple connection problem, global warming directly corresponds to "warm winter", "cold winter" or "whether a process is cold or not". Global warming means that the global average annual temperature is generally high. Affected by climate events, there will still be fluctuations in temperature and warmth in individual years.

Many important environmental factors on the earth enable the earth to breed life, among which liquid water, atmosphere and oxygen are essential factors. Most creatures living on the earth need oxygen to maintain their lives, and plants play an important role in maintaining the balance of carbon and oxygen on the earth.

The atmosphere already contains a certain amount of carbon dioxide, and industrial emissions lead to an increase in the amount of carbon dioxide, which suddenly leads to climate warming. It has directly led to the melting of glaciers in the North and South Poles, which is likely to lead to sea level rise in the future, and some island countries and some territorial countries may face great dangers.

Global warming is not just a phenomenon that happened in the past 100 or 200 years. There are many signs on the earth that the earth has experienced many global warming events, which have reduced the oxygen content on the earth and led to extinction.

In recent years, global warming has led to an increase in the frequency and intensity of extreme weather events such as cold wave. The energy of the global atmosphere is conserved. Climate warming keeps a certain area extremely hot, and the temperature around it will drop, resulting in extreme weather such as high temperature heat wave, drought, flood, typhoon and cold wave.
