Higher urban temperatures result in lower labour productivity levels and economic outputs  . Globally, urban heat stress is projected to reduce labour capacity by 20% in hot months by 2050 compared with a current 10% reduction . Burke et al.  demonstrate a nonlinear relationship between temperature and global economic productivity, with potential global losses of 23% by 2100 due to climate change alone. In specific cases, Zander et al.  estimate heat-related reductions in urban labour productivity in Australia to cost USD 3.6-5.1 billion yr-1, based on self-reported performance reduction and absenteeism among 1726 workers in 2013-142; while the high-temperature subsidies given in China at outdoor air temperatures above 35℃ are projected to increase to USD 35.7 billion yr-1 after 2030  3.
