Abstract

Working in hot and potentially humid conditions creates health and well-being risks that will increase as the planet warms. It has been proposed that workers could adapt to increasing temperatures by moving labor from midday to cooler hours. Here, we use reanalysis data to show that in the current climate approximately 30% of global heavy labor losses in the workday could be recovered by moving labor from the hottest hours of the day. However, we show that this particular workshift adaptation potential is lost at a rate of about 2% per degree of global warming as early morning heat exposure rises to unsafe levels for continuous work, with worker productivity losses accelerating under higher warming levels. These findings emphasize the importance of finding alternative adaptation mechanisms to keep workers safe, as well as the importance of limiting global warming.

Drew Shindell is Nicholas Professor of Earth Science at Duke University. From 1995 to 2014 he was at the NASA Goddard Institute for Space Studies in New York City and taught at Columbia University. He earned his Bachelor's at UC Berkeley and PhD at Stony Brook University, both in Physics. He studies climate change, air quality, and links between science and policy. He has been an author on >250 peer-reviewed publications, received awards from Scientific American, NASA, the NSF and the EPA, and is a fellow of AGU and AAAS.

He has testified on climate issues before both houses of the US Congress (at the request of both parties), developed a climate change course with the American Museum of Natural History, and made numerous media appearances as part of his outreach efforts. He chaired the 2011 UNEP/WMO Integrated Assessment of Black Carbon and Tropospheric Ozone, and was a Coordinating Lead Author on the 2013 Fifth Assessment Report of the IPCC and on the 2018 IPCC Special Report on 1.5°C. He also chairs the Scientific Advisory Panel to the Climate and Clean Air Coalition of nations and organizations.
