Abstract

Global climate change will increase outdoor and indoor heat loads, and may impair health and productivity for millions of working people. This study applies physiological evidence about effects of heat, climate guidelines for safe work environments, climate modeling, and global distributions of working populations to estimate the impact of 2 climate scenarios on future labor productivity. In most regions, climate change will decrease labor productivity, under the simple assumption of no specific adaptation. By the 2080s, the greatest absolute losses of population-based labor work capacity (in the range 11% to 27%) are seen under the A2 scenario in Southeast Asia, Andean and Central America, and the Caribbean. Increased occupational heat exposure due to climate change may significantly impact on labor productivity and costs unless preventive measures are implemented. Workers may need to work longer hours, or more workers may be required, to achieve the same output and there will be economic costs of lost production and/or occupational health interventions against heat exposures.

  • The negative impacts of heat stress will likely increase due to climate change, particularly in countries in arid and tropical zones.

    “The negative impacts of heat stress will likely increase due to climate change (Spector and Sheffield, 2014; Acharya et al., 2018), particularly in countries in arid and tropical zones (Kjellstrom et al., 2009; Andrews et al., 2018).”

    From Assessment of Heat Stress Exposure among Construction Workers in the Hot Desert Climate of Saudi Arabia (2019) · cites this paper as Kjellstrom et al., 2009

    The Results (page unavailable) project heat-related labour-productivity losses in several tropical regions, supporting the claim for those areas. The Introduction says heat strain can occur in arid climates, but the paper does not identify arid regions as particularly affected by future climate change; its tabulated projection for North Africa/Middle East is comparatively small. (LLM, conf=0.82)

  • Climate change between 1975 and 2050 would reduce the available work hours in all regions.

    “Results showed that climate change between 1975 (as the median year of the period for which climate data were used) and 2050 would reduce the available work hours in all regions.”

    From Heat, Human Performance, and Occupational Health: A Key Issue for the Assessment of Global Climate Change Impacts (2016) · cites this paper as [42]

    The Methods (page unavailable) use 1961–1990 as the baseline and 2040–2069 as the 2050s period, so the dates are reasonable midpoints. Table 3 (Figures and Tables; page unavailable) projects more work time lost in every region under an A2 sensitivity analysis that holds labour patterns constant. The claim omits that condition: Table 2, which allows labour patterns to change, projects gains or no additional loss in some regions. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The estimated reductions in available work hours at the population level varied between 0.2% for Australasia and 18.6% for Central America.

    “The estimated reductions at the population level varied between 0.2% for Australasia and 18.6% for Central America.”

    From Heat, Human Performance, and Occupational Health: A Key Issue for the Assessment of Global Climate Change Impacts (2016) · cites this paper as [42]

    Table 3 (Figures and Tables; page unavailable) reports 0.2% for Australasia and 18.6% for Central Latin America under the A2 scenario in the 2050s. But these are not the full range of regional reductions in that column: Southern Latin America is 0.1%, and some regions show no loss or a gain. The sentence also omits the scenario and period. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Using the WBGT index and the international standard for safe work, Kjellstrom et al. made quantitative, worldwide estimates of the impacts of increasing workplace heat on global and regional populations as a result of climate change.

    “Using the WBGT index and the international standard (34) for safe work, Kjellstrom et al. (42) made quantitative, worldwide estimates of the impacts of increasing workplace heat on global and regional populations as a result of climate change.”
  • Other highly affected regions were Southeast Asia (18.2%), West Africa (15.8%), Central Africa (15.4%), Oceania (15.2%), the Caribbean (11.7%), and South Asia (11.5%).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
