Hong Kong is grappling with increasingly erratic and extreme weather patterns, a direct consequence of climate change, according to Leung Wing-mo, a former assistant director of the Hong Kong Observatory.
The city recently endured its fourth black rainstorm signal within a week, causing widespread disruptions, flooding, and landslide warnings.
The Impact of Extreme Weather on Hong Kong
Hong Kong’s recent series of black rainstorm signals has wreaked havoc across the city.
On Tuesday alone, over 355.7 millimeters of rain had fallen at the Observatory’s Tsim Sha Tsui headquarters, setting a new August record for daily rainfall since records began in 1884.
This intense deluge not only inconvenienced everyday life but also posed severe risks to public safety.
The flooding made its presence felt across multiple areas, including Po Lam, where a car park saw 20 vehicles partially submerged.
At Queen Mary Hospital, patient diversions were necessary due to rising waters.
Several MTR exits were temporarily closed due to excessive flooding, while dozens of flights at Hong Kong International Airport experienced delays.
The Drainage Services Department reported handling 25 cases of flooding, underscoring the infrastructural strain these weather events impose.
A Historical Context for Hong Kong’s Extreme Weather
While these recent storms were severe, Leung Wing-mo notes that they do not compare to historical disasters like the infamous “618 landslide” of 1972 or the record-breaking floods of September 2023.
However, he stresses that the increasing frequency and intensity of such extreme weather events point to a worsening climate crisis.
The city’s infrastructure, while advanced, remains vulnerable to the unpredictability brought about by global climate change.
Climate Change and Its Role
The volatility in weather patterns underscores the pervasive influence of climate change on Hong Kong’s natural systems.
Warmer global temperatures contribute to a more dynamic atmosphere, resulting in abnormal rainfall extremes, stronger typhoons, and higher risks of landslides in steep terrains.
As a densely populated urban hub, Hong Kong faces unique challenges in mitigating and adapting to these adverse conditions.
The Need for Proactive Measures
As the climate crisis deepens, Hong Kong must actively prepare for more intense and frequent weather disruptions.
Leung Wing-mo has called for improved coordination among government departments to ensure a swift and effective response during extreme weather events.
From enhancing flood management systems to updating public safety protocols, urban planning must prioritize resilience against climate-related risks.
Residents, particularly those living in flood- or landslide-prone areas, are advised to take personal precautions.
Simple measures such as staying indoors during heavy rain, monitoring weather warnings, and preparing emergency supplies can make a significant difference in ensuring safety.
Adapting to a Changing Climate
The Hong Kong Observatory predicts unsettled weather and heavy showers to persist for the coming days.
Although rain is expected to ease by Thursday, the city will face sweltering temperatures over the weekend, showcasing the erratic nature of current weather patterns.
So, how can Hong Kong adapt effectively to this reality?
The Larger Picture
Hong Kong’s challenges mirror the global impacts of climate change. This serves as a stark reminder of the urgent need for collective action.
Governments, businesses, and citizens must work together to address both mitigation and adaptation strategies. As the city continues to face unsettling weather extremes, prioritizing sustainability and resilience is crucial.
Although the recent black rainstorm signals were not catastrophic, they offer a sobering forecast of what lies ahead. By proactively addressing vulnerabilities and integrating climate considerations into urban planning, Hong Kong can strengthen its defenses.
