Guangzhou
China
Guangzhou is projected to face a future characterized by frequent and severe heatwaves, posing health risks and straining energy resources. The city will also experience heavy rainfall events, which will likely increase the risk of flooding, compromising infrastructure and community safety. Additionally, the risk of arbovirus transmission is expected to rise, increasing the prevalence of diseases such as dengue fever. Furthermore, an elevated malaria risk looms as warmer conditions may expand ideal habitats for the mosquitoes that carry the disease. These climate hazards are interconnected, pointing to significant vulnerabilities in public health and urban resilience as the city confronts an uncertain climate future. Addressing these challenges promptly is essential for protecting the well-being of the population.
Hazard Outlook
How will Guangzhou's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Maximum Rainfall
Guangzhou's projected maximum rainfall of 15 mm is among the highest of all cities globally.
Elevation
At 84 m elevation, Guangzhou faces elevated risk from coastal flooding and sea level rise.
Maximum Temperature
Guangzhou's projected maximum temperature of 9.2°C is near the median of cities globally under a 3.0°C warming scenario.
Longest Heatwave
Guangzhou may experience heatwaves lasting up to 4 days, near the median of other cities.
Heavy Rainfall Days
With 10 days of heavy rainfall expected, Guangzhou ranks near the median of cities for extreme precipitation events.
Exposure Summary
Adaptation Priorities
Guangzhou faces high exposure to max rain and elevated exposure to elevation. These areas may warrant priority attention in adaptation planning.
