Summary

This video features an interview with Philippe Grandcolas, an ecologist and research director at CNRS, discussing the impacts of heatwaves on living organisms. The conversation begins by critiquing the media focus on air conditioning, arguing that it distracts from the broader ecological crisis. Grandcolas explains that while some species are adapted to high temperatures, many are not, and heatwaves cause stress, reduced photosynthesis, and mortality in plants. He details the physiological mechanisms, such as stomatal closure and protein denaturation, and discusses the vulnerability of animals, particularly birds and livestock. The interview also covers the simplification of ecosystems, the risk of food shortages, and the emotional response of scientists to the crisis. The discussion highlights the need for systemic change and adaptation, emphasizing that nature cannot be air-conditioned.
