The concept of wet-bulb temperature is now key in understanding how global warming impacts health. But where did this idea come from?  It started with a scientist named J. S. Haldane. He looked at working conditions in mines during the early 1900s.  The first signs of a warming world were felt in workplaces, not globally. This made it a prime spot for studying how heat affects workers.  Haldane found that there was a point where heat made workers less effective.  This was a big deal because it showed a conflict between the conditions needed for work and the needs of the workers themselves.

Workers were not silent about this.  For example, weavers in Lancashire fought against what they called "steaming" conditions.  They were early advocates for better working environments.  This fight over heat in the workplace can be seen as a form of thermopolitics.  It is about controlling and arguing over temperatures.  It was not just about setting rules.  It was also about two different views: one that focused on numbers and efficiency, and another that focused on the quality of life and well-being.  This debate invites us to think about how we can have a say in the air we breathe at work.

The wet-bulb temperature threshold used in some recent studies might be too high.  This means that the point at which heat becomes dangerous for humans could be reached sooner and in more places than expected.  Without strong action, the situation could become critical.  This is a call to think critically about the conditions we work in and the power we have to change them.  It is also a reminder that the fight for fair working conditions is ongoing.  It is not just about the past, but also about the future.

The history of thermopolitics shows that workers have always had to fight for better conditions.  It also shows that the science behind these fights is complex and ever-changing.  Understanding this history can help us make better decisions about how to protect workers in a warming world.  It can also help us think about how to create a more democratic way of managing the air we breathe.  This is not just about setting rules.  It is about creating a system where everyone has a voice.
