Summary Extreme heat induced by climate change will cause profound adverse consequences for work, human performance, daily life, and the economy in large parts of the world. The increasing temperatures are the most predictable effects of climate change, and all models of future trends show significant increase this century. The heat problems will become even worse in the next one or two centuries, depending on the global climate policies established this year. The global areas worst affected by extreme heat will be tropical countries,

First paragraph of book chapter: The human body has behavioural and physical mechanisms that work to maintain its core temperature at about 37°C. If the body’s internal temperature rises above this level, then body systems and vital physiological functions are compromised, and in severe cases, death can result. The climatic conditions relevant to such heat stress may be measured in terms of the Wet Bulb Globe Temperature (WBGT), which takes account of temperature, humidity, wind speed, and solar radiation.1 We calculate WBGT for in-shade (no

Ambient heat exposure is a well-known health hazard, which reduces human performance and work capacity at heat levels already common in tropical and subtropical areas. Various health problems have been reported. Increasing heat exposure during the hottest seasons of each year is a key feature of global climate change. Heat exhaustion and reduced human performance are often overlooked in climate change health impact analysis. Later this century, many among the four billion people who live in hot areas worldwide will experience significantly reduced work capacity owing to climate change.

Occupational health is particularly affected by high heat exposures in workplaces, which will be an increasing problem as climate change progresses. People working in jobs of moderate or heavy work intensity in hot environments are at particular risk, owing to exposure to high environmental heat and internal heat production. This heat needs to be released to protect health, and such release is difficult or impossible at high temperatures and high air humidity. A range of clinical health effects can occur, and the heat-related physical

With a view to occupational effects of climate change, we performed a simulation study on the influence of different heat stress assessment metrics on estimated workability (WA) of labour in warm outdoor environments. Whole-day shifts with varying workloads were simulated using as input meteorological records for the hottest month from four cities with prevailing hot (Dallas, New Delhi) or warm-humid conditions (Managua, Osaka), respectively.

Estimating population heat exposure and impacts on working people in conjunction with climate change

Increased environmental heat levels as a result of climate change present a major challenge to the health, wellbeing and sustainability of human communities in already hot parts of this planet. This challenge has many facets from direct clinical health effects of daily heat exposure to indirect effects related to poor air quality, poor access to safe drinking water, poor access to nutritious and safe food and inadequate protection from disease vectors and environmental toxic chemicals. The increasing environmental heat is a threat to environmental sustainability.

Extreme Heat and Migration

The impacts of climate change on global temperatures profoundly affect people’s ability to sustain their livelihoods as well as their health; both of these dimensions in turn influence the migration of people. Indeed, increasing heat related to climate change is likely to result in more disruptive events, such as frequent droughts, wildfires, episodes of extreme temperatures and heat waves. Such events are already directly and indirectly displacing large numbers of people each year and likely to lead to the migration of more people in the future.
