Study Notes
Hong Kong Climate Change
- Hong Kong's annual mean temperature has increased by 1.7°C since 1885, faster than the global average of 1°C.
- The rate of temperature increase has accelerated in recent decades.
- As Hong Kong gets hotter, the number of hot nights and very hot days increases, while cold days decrease.
- Annual rainfall has slightly increased, though the number of rainy days has decreased, meaning rainfall intensity is higher.
- There are more days with heavy rainfall (over 30 mm/hour) and extreme rainfall events (over 100 mm/hour).
- Cloud cover and thunderstorm days have increased.
- Wind speed in urban areas has decreased, while rural areas remain stable.
- Annual mean temperature in Hong Kong is predicted to rise by 3-6°C by 2100.
- Potential for summers to become longer and hotter, with possible loss of winters entirely by 2100.
- Possible loss of three cold days in Hong Kong by 2100.
- Global climate change and urban development are contributing factors to Hong Kong's changing climate.
Urban Development's Effect
- Increased urban areas, reduced vegetation cover, and taller buildings lead to a heat island effect, increasing temperatures.
- Converting rural areas to urban areas negatively impacts the local climate.
Possible Effects of Climate Change
- Increased risk of landslides, coastal flooding and storm surges given stronger typhoons and rising sea levels.
- Disruptions in traffic and peoples' daily routines due to extreme weather events will happen.
- Impacts on telecommunications due to extreme weather events.
- Increased food prices from reduced production elsewhere.
- Potential for increased heat stroke cases and spread of dengue fever.
- Damage to wildlife habitats in nature reserves due to rising sea levels and warmer seawater.
- Coral bleaching in marine habitats.
