Climate change is negatively affecting working conditions and labour productivity in North America  . Working conditions in temperatures above a heat index of 85ºF  are correlated with potentially hazardous health conditions , and for every degree Celsius increase in temperature, labour productivity is estimated to be reduced by 0.11% for low-risk workers and 0.53% for high-risk workers  . By mid-century , temperature increase, changing water availability and SLR are projected to result in a 0.6% drop in labour productivity in auto, timber, textile and chemical manufacturing in the southeast and Texas regions . Labour productivity in the US automobile industry decreases by 8% for every six or more days of consecutive unusually hot weather  . Thirty percent of California workers are employed in high-risk industries, such as agriculture, with exposure to high temperature leading to loss in productivity . Under RCP8.5 increases in extreme temperatures, labour productivity in the USA is projected to decrease, costing 190 billion USD in lost wages by 2090 .
