Why is global warming, which was hotly debated a few years ago, rarely mentioned now? Is it solved? As early as a few years ago, scientists proposed. Global warming? Slogan. But recently? Global warming? It doesn't often appear in people's mouths, but it really affects the living environment of human beings!

I don't know how many people pay attention to the annual temperature change, especially in summer; Even without deliberate observation, you should be able to feel the annual temperature change, especially in recent years. Whether it's summer or winter, the temperature is getting higher every year. I believe that many people will only lament global warming when facing this problem, but is global warming a real fact? Why do many people doubt the truth of global warming?

By studying the temperature fluctuation data in recent decades to hundreds of years, scientists have come to the conclusion that global warming does exist, at least there is no new evidence against it at present, and this warming is mainly caused by a large number of greenhouse gases emitted by human beings. In addition to human factors, there are many factors that have an impact on global warming, so I won't go into details here. Interested friends can refer to it themselves.

Since it is a human problem, how does human influence it? At present, it is certain that the human influence on global warming in the past 150 years is enormous. With the development of human society and the continuous progress of science and technology, greenhouse gas emissions are increasing; Moreover, more and more people develop the surface, and a large number of vegetation and aerosols are destroyed, resulting in reduced radiation absorption; So global warming will gradually form.

Since there is evidence to prove the influence of human beings on the greenhouse effect, why are there many doubts or even objections to the authenticity of the greenhouse effect? In fact, what they oppose is not the greenhouse effect, but the influence behind it. As the topic is sensitive, as for the reason, as everyone knows that Bian Xiao is here, I won't describe it in detail.

Global warming will inevitably cause adverse effects and consequences. Only by vigorously promoting energy conservation and emission reduction and doing what we should do, our home will not be hurt more. This article only represents personal views.
