The research aims to substantiate the relevance of developing the concept of the ecological technosphere as the most important element of the climatic stability of today’s socio-natural complexes. The main research methods used were an analytical review of scientific literature on the ecology of sustainable development and climatic conditions of socio-natural systems, the methods and principles of dialectics, and sphere and evolutionary approaches. According to the study of the current state of the solution to the problems of climate resilience of socio-natural systems, developments are being carried out in several main directions. The most active areas raise questions about the need to balance the damage caused by human activities with efforts to restore nature. Many studies in this field highlight the symbiosis between technical and environmental aspects of human activity rather than focusing on each sector separately. However, more scientific publications need to address the development of a new integral sphere of society. In this research, the authors propose and justify the need to develop the concept of the ecological technosphere. This concept will help create programs for integrated activities in environmental engineering and technology, emphasizing an initial careful approach to nature and its resources.
