Impact of global warming on extreme hot and cold weather

After the industrial revolution, carbon dioxide emissions have continued to grow rapidly and global warming has become evident. Along with the warming, heat waves, cold waves, and protracted droughts are only a few examples of the extreme weather and climatic phenomena that additionally happened regularly, causing many casualties and property damages. In order to offer a foundation for future decision-making about the avoidance and reaction to severe hot and low temperature weather, we analyzed the reaction of future temperature to rising temperatures in the context of global heating in this study. This paper first analyzed the impact of global warming on extreme hot weather based on the Fifth Assessment Report of the United Nations Intergovernmental Panel on Climate Change(IPCC), in terms of the probability of occurrence of extreme hot weather when the average and temperature variance increase individually and together. Secondly, by examining the causes of the intensified polar vortex brought on by stratospheric warming as in setting of climate warming, the effects of global warming on extreme low degree weather were examined. The findings demonstrated that climate warming had an important impact on the occurrence of extreme high and low temperature weather. Warming on the one hand may make the average temperature and temperature variance change in some regions larger, and extreme high heat occurrences are more likely to occur as the temperature's average and variation both rise. Warming on the other hand will warm the stratosphere, which in turn will cause the asymmetric polar vortex to strengthen, making extreme low temperature events more likely to occur.
