Climate Change Impacts in HK

In Hong Kong, data from The Hong Kong Observatory reveals a notable rise in the number of days with maximum temperatures exceeding 33.0°C, increasing from around 10 days in 2001 to 54 days in 2022. Moreover, the annual mean temperature climbed from 23.5°C in 2005 to 24.5°C in 2023, marking a significant uptick over the past two decades. 

These shifts align with global warming trends attributed to human activities, notably the release of greenhouse gases such as carbon dioxide and methane. The temperature escalation contributes to heightened occurrences of severe heat waves globally, including in Hong Kong, presenting various risks to public health, ecosystems, agriculture, and infrastructure. Immediate measures are imperative to mitigate greenhouse gas emissions and address the repercussions of climate change. Sustainable development means meeting current needs while preserving resources for future generations. To ensure environmental sustainability, reducing greenhouse gas emissions is crucial.
