Climate change is one of the most intuitive changes in global warming. As a result of a large amount of carbon dioxide emissions, there is a sharp rise in high-temperature weather, which has an irreversible impact on our environment and ecology. Scientists say, “Changing weather patterns linked to rising global temperatures have resulted in a dearth of wind across northern China, according to several recent studies, exacerbating a wave of severe pollution that has been blamed for millions of premature deaths”. However, when I returned home last Christmas, there was no snow on the street, instead, it was a warm winter with sunshine. The continued of global warming may not only bring about changes in climate. The world may undergo more unpredictable changes due to global warming in the future.

Global warming has become a very difficult trend to reverse. It and rising temperatures have caused very serious consequences for human beings, brought great impact on the Earth’s organisms and seriously affected people’s lives, but people didn’t realize the seriousness of the problem.
