Abstract The Paris Agreement proposed two global warming levels relative to the preindustrial period, with ideal objective of 1.5°C and an upper boundary 2.0 °C. However, years when temperature will first reach 1.5 or 2.0°C vary in different regions. Therefore, climate extremes their population exposure are still not clear at regional levels.

Abstract The middle and lower reaches of the Yangtze River are frequently affected by Western Pacific Subtropical High (WPSH) in summer. This leads to phenomena including air subsidence, high temperatures, low rainfall, weak winds, all which affect urban heat island (UHI) effect. Currently, there few studies on influence WPSH UHI In this study, we analysed temporal spatial distributions effect establishing two scenarios: with without WPSH. We calculated intensity proportion index (UHPI) analyse geographical detector method was then used factors influencing UHI. results indicate strong during day provincial capitals some developed cities. area larger under than years UHPI at both night, although more pronounced night. affecting daytime mainly POP NTL, O3 plays a large role control. main night AOD, NTL were control, interactions multi-factors daytime, DEM nighttime. It found that enhanced control WPSH, diurnal differed ultimately provides realistic suggestions for mitigating areas
