Changsha
China
Changsha is projected to face a future where extreme heat becomes more prevalent, with dangerous heat extremes threatening public health and safety. The city will experience an increase in heavy rainfall events, leading to more frequent and intense precipitation. This scenario poses significant risks of flooding and water drainage challenges, impacting infrastructure, agriculture, and the safety of residents. The interaction of these climate hazards will likely exacerbate vulnerabilities within the urban landscape, necessitating a comprehensive assessment of climate resilience measures. As these challenges unfold, proactive strategies will be essential to mitigate the adverse effects of climate change in Changsha and protect its communities.
Hazard Outlook
How will Changsha's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Maximum Rainfall
Changsha's projected maximum rainfall of 14 mm is among the highest of all cities globally.
Maximum Temperature
Changsha's projected maximum temperature of 10.2°C is higher than most cities globally under a 3.0°C warming scenario.
Heavy Rainfall Days
With 11 days of heavy rainfall expected, Changsha ranks higher than most cities for extreme precipitation events.
Elevation
At 41 m elevation, Changsha faces elevated risk from coastal flooding and sea level rise.
Longest Heatwave
Changsha may experience heatwaves lasting up to 4 days, near the median of other cities.
Exposure Summary
Adaptation Priorities
Changsha faces high exposure to max rain and elevated exposure to max temp, heavy rain, elevation. These areas may warrant priority attention in adaptation planning.
