Abstract: Climate change is already inducing substantial adverse economic and health effects. Here we show that climate is warming faster in China versus the global Earth, and that this warming is more pronounced in the northern Chinese provinces. The recent rise in extreme events such as heatwaves, drought and floods have increased related deaths and risk of diseases such as dengue and infectious diarrhoea. Climate-related economic loss has increased by 1.5 fold from 2022 to 2023. In cities, the total urban warming is now the addition of both the recent, global-warming related extreme heat exposure, and the classical urban heat island effect (Fig. 1). This has fostered the recent development of urban cooling strategies such as ventilation corridors in Guangzhou.
