Climate change poses serious health risks to people worldwide. Vulnerable populations are more affected due to factors like poverty and weak healthcare systems. To address these risks, public health responses are needed to reduce negative impacts and increase resilience. Research is ongoing to understand how climate change will impact health, especially in China. It is crucial to estimate regional health risks, identify dangerous health consequences, and detect health effects caused by climate change. Collaboration between individuals, communities, governments, and researchers is essential to develop effective strategies to protect public health from the impacts of climate change.
