The public perception of global natural processes in the climate change context plays an important role in modern political decision-making; and the country’s future depends on the younger generation. This survey was aimed at revealing public attitude to changes in global natural processes among the participants and organizers of the Thirteenth All-Russia Competition of children’s environmental projects “Man on Earth”. An online questionnaire “Biospheric processes, their understanding and consideration in your own research and environmental activities” was offered for completion in February–March 2023. We received 1173 voluntarily completed questionnaires from the respondents aged 6 to 60 and older. More than 70 % of respondents consider human activity to be the cause of global climate changes, with the majority of respondents having a negative attitude to climate warming. However, be there a possibility of climate management, the majority of respondents would like climate warning at a local level. With age, the number of those wishing for climate stabilization (return to the climatic norm) increases. Approximately 50 % of the respondents consider that global natural processes directly affect the status of the environment. At the same time, only 10 % attribute the unfavorable state of the environment to global factors. People aged over 60 are most concerned about global environmental problems.
