Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Climate change has had a detrimental impact on global health, particularly through the rise of extreme heatwaves. Presently, the early warning system for heatwave-related health risks can forecast potential dangers several days in advance; however, long-term warnings fall short. WHAT IS ADDED BY THIS REPORT? This report introduces a novel early warning system aimed at predicting heatwave-induced health risks in China at sub-seasonal to seasonal timescales. The outcomes of the assessment suggest this system holds significant potential. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICES? The system facilitates advanced assessment of both the scale and dispersal of risk among various demographic groups. This allows for the proactive management of potential risks with extended lead times.
