title = "Contributions of Global Warming and Urbanization to the Intensification of Human-Perceived Heatwaves Over China",
abstract = "Urbanization and global warming are the two major drivers of the warming environment in cities. The contributions of urbanization and global warming to the past occurrence of human-perceived heatwaves (HWs) over China are evaluated in this study. Both observations and model simulations show HWs have become more intensive, longer-lasting, and more frequent in recent decades. Urbanization and greenhouse gases contribute to 21.9% and 72.9% of the intensification of HWs, respectively. The occurrence probability of observed human-perceived HWs has doubled over 1961–2012 and is projected to be about 4.36/5.92 times under the 1.5/2°C warming relative to the preindustrial level. At the 3.5°C warming, the average duration of HWs is projected to increase to 43.63 days/year, and the occurrence probability is expected to increase by 11.95 times, 91% of which is attributable to human-induced warming. The highest sensitivity of the increases in HWs due to human-induced warming is in Southern China.",
