Projections using CMIP5 data show increasing wet-bulb temperatures and longer warm seasons in Hong Kong, posing serious public health challenges by the end of the century.
A study highlights how climate change-induced rainfall increases could overwhelm Hong Kong’s landslide emergency response system, stressing the need for improved slope safety measures.
Using CMIP5 climate models, the Hong Kong Observatory projects rising rainfall intensity, more frequent extreme rainfall events, and longer consecutive wet days by 2100.
Climate change and extreme rainfall heighten landslide risks in Hong Kong, requiring advanced technologies and holistic management strategies for resilience.
Sea level rise will worsen flooding in Hong Kong and PRD, displacing 100,000 annually by 2100, requiring urgent adaptation.
A time-stratified study in Hong Kong highlights the critical impact of consecutive hot nights and non-consecutive heat on mortality, underscoring the need for enhanced heat-health monitoring.
A spatial study of heat health risk in Hong Kong identifies high-risk areas, revealing shifting hotspots and key factors driving vulnerability for improved localised action plans.
A study of Hong Kong's rainfall from 1984 to 2010 links abrupt increases in extreme precipitation intensity and frequency to atmospheric circulation patterns and monsoon variability.
Pseudo‑global‑warming simulations of three major Pearl River Delta cyclones suggest stronger storms and higher surges, with sea‑level rise lifting late‑century storm‑tide levels by ~1 m.
A study links sea level variations in the South China Sea to warm and cold phases, driven by atmospheric heat flux, water advection, and Pacific climate variability.
A study finds typhoon intensity significantly impacts storm surges, while sea level rise drives higher wave heights, exacerbating flood risks in low-lying coastal areas.
The Pearl River Delta could see sea levels rise by up to 1.94 metres by 2100, potentially submerging around 8,570 square kilometres of land and calling for strengthened coastal planning and adaptation.
A study mapped extreme heat risk in Hong Kong, revealing worsening conditions and identifying high-risk urban hotspots driven by population density and socio-economic vulnerabilities.
Research reveals tropical cyclones contribute 25% of Hong Kong's summer and autumn precipitation, with changing patterns showing decreased cyclone-related rainfall but increased non-cyclone rainfall events.
Third assessment on impacts of climate change on tropical cyclones in the Western North Pacific projects fewer storms, higher intensity, and greater storm surge risks linked to sea level rise.
Using CMIP5 models, projections show Hong Kong’s temperature could rise by 2.2ºC to 4.2ºC by 2100, depending on greenhouse gas emissions scenarios.2
Modelling suggests sea levels near Hong Kong could rise by up to 0.84 metres this century, driven by land subsidence and global ice loss.
Recent findings indicate limited evidence of climate change effects on Western Pacific cyclones but confirm increasing storm surge risks
Retrospective analysis of hospital admissions in Hong Kong highlights the health effects of extreme temperatures, weather patterns, and pollution, with admissions rising during both hot and cold seasons.
Projections show a decline in tropical cyclone landfalls in South China due to shifting genesis patterns but predict stronger landfalling storms under warmer climate conditions.
