Why is the weather so abnormal in 2023?

The abnormal weather in 2023 is mainly caused by global climate change. Global warming leads to unstable climate system and frequent extreme weather events. First of all, increasing greenhouse gas emissions aggravate the greenhouse effect of the earth's atmosphere, leading to an increase in the global average temperature. This has led to the increase of extreme high temperature, drought and heat wave, affecting agriculture, water resources and ecosystems. Second, rising ocean temperatures have triggered more intense hurricanes and rainstorms, leading to floods, storms and rising sea levels. In addition, the complexity of the global climate system is also one of the reasons for the abnormal weather, involving the interaction of various factors such as atmospheric circulation and ocean circulation. Although it is difficult to predict the occurrence of specific weather events, the trend of global climate change is obvious, and action is needed to deal with climate change.
