Historically, Indiana’s labor capacity—the percentage of hours available for outdoor work in a 24-hour period—has been about 99 percent on average, meaning extreme heat rarely affects our work force. By mid-century, as global temperatures increase by 3 to 4.5°F, Indiana’s labor capacity is projected to decline to about 95 percent for both the high- and medium-emissions scenarios.
Labor capacity will continue to decline by late century as global temperatures rise, with a projected average labor capacity of 89 to 95 percent based on high- and medium-emissions scenarios, respectively.
