The study raises an urgent and important problem of the climate change. The research area is the Rostov region of the Russian Federation. The paper considers the features of the change of the climatic conditions of the region and assesses the consequences. The dynamics of the average monthly temperature in January and July in Rostov-on-Don, as well as its average annual precipitation from 1970 to 2019, is analyzed. The research is based on the weather chronicle of the Rostov region. Over the past 60 years, there had been a steady increase in the average monthly temperatures. The work also considers the issue of desertification processes in the study area, its impact on human life activity.

Eutrophication of water bodies has a negative impact on human health, contributing to the spread of the gastrointestinal and dermatological diseases, conjunctivitis. The increase of the anthropogenic load leads to the increase of the eutrophication level and, consequently, the increase in morbidity. The article discusses in detail the eutrophication of the Gulf of Taganrog of the Sea of Azov. The conclusions made in the work relate to the direct relationship between the degree of eutrophication of the reservoir, water temperature, salinity and the spread of gastrointestinal diseases.

From the essential approach position, the modern educational organization formation and performance are considered in the article as a scientific-educational, learning, socio-cultural object that meets the society requests; the modern teacher education priorities and development directions are determined; the development of the modern pedagogical knowledge prospects is emerged, which are formed under the new education paradigm conditions, which are characterized by digitalization, networking, distance transmission of information, the subject's generation of all possible alternatives to reveal individual's personal balance; the research process dynamics and methodological optics of a modern university is analyzed; the rational use of the teacher education available resources is discussed; the methodological practice and ways of the new practices subsequent multiplication in university education the system are reflected; the factors, affecting a modern subject education quality are established; the degree of the mediated product influence on the modern teacher university educational strategy implementation is determined; the training and educational tools of the marketable specialist are investigated; an approach is implemented that identifies a modern student in his/her development, which helps to determine the pedagogical matter motion state, to recreate a coherent picture of the available stocks and funds, necessary for the individual's education at the qualitative.

One of the most difficult for solving environmental problems of water bodies around the world is the ever-accelerating processes of eutrophication, which are currently mostly anthropogenic in nature. The aim of the work is to identify the biogenic matter that has the greatest influence on the processes of eutrophication and, consequently, limits this process. To clarify this agent of eutrophication, a model experiment was carried out, consisting of a series of tests with the natural water sampled from the Gulf of Taganrog of the Sea of Azov. When solving the problem of the need for and the degree of removal of the biogens from the wastewater, first, the attention should be paid to the biogen that limits the eutrophication of this water system.

The work provides a comprehensive environmental assessment of the eutrophic biogenic load on a water body using the example of the Gulf of Taganrog of the Sea of Azov. This study is carried out with the aim of a deeper understanding of the ecological state of the waters of the Gulf of Taganrog, the processes of its eutrophication. The assessment of the biogenic load on the water area is carried out. The conducted researches showed that the eutrophication of the Gulf of Taganrog northeastern part depends on the salinity, water temperature, ammonium, and nitrate and phosphate concentrations. The level of the internal and external loads of phosphorus in the waters of the Gulf of Taganrog is approximately equal.
