Shanghai
China
Shanghai is projected to experience increased risks from heavy rainfall events, which are anticipated to become more intense as climate change progresses. The city’s low-lying coastal geography heightens its vulnerability, leading to possible urban flooding, waterlogging, and infrastructure disruptions. Increased rainfall can also result in hazardous runoff, deteriorating water quality and public health. Moreover, the interaction between rising sea levels and heavy precipitation exacerbates risks of flooding and erosion, severely impacting economic activities and living conditions. As these climate hazards are expected to worsen in the future, the need for awareness and proactive measures becomes critical. Stakeholders must prepare to address these climate challenges to safeguard the city’s resilience.
Hazard Outlook
How will Shanghai's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Elevation
At 7 m elevation, Shanghai faces very high risk from coastal flooding and sea level rise.
Maximum Rainfall
Shanghai's projected maximum rainfall of 16 mm is among the highest of all cities globally.
Maximum Temperature
Shanghai's projected maximum temperature of 9.6°C is higher than most cities globally under a 3.0°C warming scenario.
Longest Heatwave
Shanghai may experience heatwaves lasting up to 6 days, higher than most other cities.
Heavy Rainfall Days
With 9 days of heavy rainfall expected, Shanghai ranks lower than most cities for extreme precipitation events.
Exposure Summary
Adaptation Priorities
Shanghai faces high exposure to elevation, max rain and elevated exposure to max temp, heatwave. These areas may warrant priority attention in adaptation planning.
