What are the characteristics of current global climate change?

The global average temperature is getting higher and higher, and the climate change rate is increasing. At present, some characteristics of global climate change are that the global average temperature is getting higher and higher, and the climate change rate is getting bigger and bigger. The global average temperature has been rising year by year, and the temperature difference is large, which affects people's normal life. The increase of climate change rate means extremely hot and cold weather, but there will be more heavy rain and less light rain, which will affect infrastructure. The adverse effects of global climate change are that high temperature and heat waves will directly cause human death, increase the geographical distribution of diseases, tropical diseases will spread to mid-latitudes, the transmission routes and scope of bacteria and viruses will become larger, and extreme weather will wreak havoc on a global scale, resulting in economic losses and personnel displacement.
