Top10news 2024｜The Indication of Climate Change​︱Author︰Chong Yin Ngai

September 2024 will go down in history as a month of extremes for Hong Kong. Residents experienced a combination of heavy rainfall and unseasonably high temperatures, making it the third hottest September on record. This unusual weather is a warning for everyone, from students to policymakers, about the changes happening of our environment. 

According to the Hong Kong Observatory, average temperatures reached an  unbelievably 29.8 degrees Celsius this September. On top of that, the city received more than 600 millimeters of rain—over 150% of the average for the month. This kind of weather isn’t just unusual, it’s alarming. It raises concerns about how climate change is affecting our daily lives and the environment we live in. 

Many people have heard about climate change, but what does it really mean?  Climate change refers to long-term shifts in temperatures and weather patterns. While the Earth’s climate has always gone through changes, human activities, like burning fossil fuels and deforestation are speeding up these changes. 

In Hong Kong, we are already seeing the results. The city has experienced hotter summers and more intense rainfall in the past years. The weather this September is just another reminder that we need to pay attention to these patterns. Scientists warn that if we don’t take action to reduce greenhouse gas emissions, we will face even more extreme weather events in the future. 

So, how does this extreme weather affect everyday life in Hong Kong? First, the combination of heat and rain can be uncomfortable and even dangerous. High temperatures can lead to heat exhaustion, especially for vulnerable groups like the elderly and those with health issues. Hospitals have reported an increase in heat-related illnesses during this period, putting pressure on our healthcare system. 

Moreover, heavy rainfall can lead to flooding. In September 2024, many areas were flooded , disrupted public transport, and damage to homes. This not only affects our daily routines but also has economic consequences. Businesses may lose revenue, and the cost of repairing damage can be significant. 

The heavy rains and high temperatures pose serious public health risks. Flooding can contaminate drinking water supplies, leading to waterborne diseases. Additionally, stagnant water can become a breeding ground for mosquitoes, increasing the risk of diseases like dengue fever. This means that the government must act quickly to monitor these health risks and ensure public safety. 

As students, it’s important to understand how these health issues can impact our families and communities. We should be aware of the signs of heat exhaustion, such as dizziness and nausea, and know how to stay safe during extreme weather. 

Given the challenges posed by extreme weather, urban planning in Hong Kong must adapt. The city is known for its high-rise buildings and limited green spaces, which can trap heat and make temperatures even hotter. To tackle this issue, city planners should consider creating more parks and green roofs, which can help cool the environment and improve air quality. 

Additionally, the drainage system needs to be improved to handle heavy rainfall. Upgrading these systems will help prevent flooding and keep roads safe for travel. This kind of forward-thinking is essential for making sure our city is prepared for the future. 

In response to the extreme weather, many community organizations have started campaigns to raise awareness about climate change and promote sustainable practices. These initiatives encourage people to reduce waste, recycle, and use public transport. As students, we can play a crucial role in these efforts by participating in school projects, joining environmental clubs, and spreading awareness among our peers. 

Public awareness campaigns are vital for educating everyone about how to prepare for extreme weather. Simple actions, like having an emergency plan and knowing where to find safe drinking water during floods, can make a big difference. 

The unusual weather of September 2024 serves as a reminder that climate change is real and affects us all. It’s not just a problem for scientists or politicians, it’s something we all need to care about. The combination of extreme heat and heavy rain challenges our daily lives and poses risks to our health and safety. 

As we move forward, it’s crucial for everyone to take action. Whether it’s pushing for better urban planning, participating in local environmental initiatives, or simply being more mindful of our daily habits, we all have a role to play. 

In conclusion, September 2024 will be remembered not just for its record-breaking temperatures and rainfall, but as a turning point for awareness and action on climate change in Hong Kong. The power to create a sustainable future lies in our hands. Let’s make sure we rise to the challenge!
