The first and second working groups of the Intergovernmental Panel on Climate Change (IPCC) recently jointly released the "Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation: Summary for Policymakers" in Kampala, the capital of Uganda, according to information from the China Meteorological Administration.

According to the report, extremely hot weather will increasingly occur globally, while cold extremes will decrease at the end of the 21st century.

The report noted that the length, frequency and magnitude of heat waves are likely to increase in many regions across the globe. It is likely that the frequency of heavy precipitation or the proportion of total rainfall from heavy falls will increase in many areas of the globe.

Average tropical cyclone maximum wind speed may increase. It is likely that the global frequency of tropical cyclones will either decrease or remain essentially unchanged. Furthermore, extreme events will have greater impact on sectors closely related to climate, such as water, agriculture and food security, forestry, health, and tourism.

There is evidence from observations gathered since 1950 of changes in some extreme events. It is likely that there has been an overall decrease in the number of cold days and nights as well as an overall increase in the number of warm days and nights on the global scale. In addition, the number of heavy precipitation events has probably increased in certain regions.
