Understanding Human Adaptation to Climate Change
Research is being conducted to explore how the human body adapts to the challenges posed by climate change as significant warming continues. France's Human Adaptation Institute is leading three deep climate expeditions to gather data on how humans respond to extreme environmental conditions, with 20 volunteer climatonauts participating in these studies. Their journey includes extreme environments such as the equatorial forests of French Guiana, the Arctic Circle, and the hot, arid Saudi Arabian Desert. The focus is on understanding physiological and psychological adaptations to high temperatures and varying humidity levels, which are critical as heat-related deaths have significantly increased in recent years.
Physiological Responses to Heat and Humidity
The body employs several mechanisms to cope with rising temperatures, such as the dilation of blood vessels to disperse heat and sweating for cooling. However, these adaptive strategies can become strained as heat waves intensify and last longer, leading to potential physical exhaustion. Climate models predict dire scenarios for future conditions, with regions facing temperatures of 35 degrees Celsius combined with 100% humidity, which could be life-threatening. Hence, understanding these physiological responses becomes essential for assessing risks and developing strategies to protect human health in the face of climate change.

Adapting to Climate Change: Human Physiological Responses
As we enter 2023, we’re desperately looking for ways to combat human-induced climate change. It’s a worthy cause, but it’s clear that some irreversible effects have already happened, and that will continue for some time.
So it would be foolish not to prepare for the reality of living on a planet which has undergone significant warming. There’s relatively little known about how our bodies will react, which is why France’s Human Adaptation Institute set up three Deep Climate expeditions to take place between December 2022 and June 2023. The project will help researchers understand better how the human body adapts to intense conditions. A team of 20 volunteer “climatonauts” with no field experience will be accompanied by explorer and project organiser Christian Clot.
What goes on during the expeditions? What bodily functions do we have to deal with climate change? In under 3 minutes, we answer your questions!
