Modern education in the context of V.I. Vernadsky’s ideas of the noösphere
The paper provides a review of the existing common education in Russia in the context of V.I. Vernadsky’s ideas of the noösphere. An analysis was made of the compliance of the content of educational standards and exemplary educational programs for the common education school with V.I. Vernadsky’s main ideas of the noösphere.
Pedagogical approaches to acquaintance with V.I. Vernadsky’s ideas in natural science museums
The paper considers the use of two pedagogical approaches, person-centered and systemic-structural, in the development and implementation of two thematic museum classes dedicated to V.I. Vernadsky’s life and scientific activities. These classes, namely, “From the soil to the biosphere” and “V.I. Vernadsky’s life and scientific activity”, were developed at the Earth Science Museum of the Lomonosov Moscow State University and aimed at in-depth acquaintance of schoolchildren with the teaching about the biosphere. The paper presents methodological materials for the classes: a description of the stages of the lessons and tasks for independent work (a crossword and a quest). Our analysis of the second lesson’s approbation showed that the schoolchildren were unanimous in their opinion: the organization of an independent search for answers to the posed questions and the leading role of the museum teacher allowed them to better accepting complex concepts and understanding the relationship of various scientific directions.
Biosphere, noösphere, and agriculture (to the 160th anniversary of the birth of V.I. Vernadsky)
The paper is devoted to the outstanding Russian scientist Vladimir I. Vernadsky, who is one of the founders of ecology. As a student of V.V. Dokuchaev, he developed his teacher’s ideas of a systematic dynamic approach to the study of nature and introduced a deep scientific ecological content into the concepts of the biosphere and the noösphere. V.I. Vernadsky is the founder of a complex of modern Earth sciences (geochemistry, biogeochemistry, radiology, and hydrogeology) and the creator of many scientific schools. In his scientific work, he covered many research areas, from geology to the study of the role of living matter in geochemical cycles, from soil science to the biosphere, the increasing influence of scientific thought, human activity in the biosphere and its transformation into the noösphere. The importance of agriculture in the biosphere and the noösphere is considered. The biosphere is an area of active life on Earth (troposphere, hydrosphere and part of the lithosphere), the composition, structure and energy of which are mainly due to the activity of living organisms. The noösphere is its thinking shell. Agriculture, whose most important part are grassland ecosystems, is an important component of the biosphere, being a reproducible, autotrophic sustainable resource (energetical, environmental, food and feed). In light of the pressing environmental problems facing the world, environmental education and environmental thinking are a priority for the development of the biosphere, the noösphere and agriculture.
Dynamics of global natural processes and V.I. Vernadsky’s teaching of the biosphere
Based on V.I. Vernadsky’s teaching of the biosphere and modern scientific data, an attempt was made to analyze the mechanisms of the dynamics of modern global processes using the example of climate changes. Possible causes of the warming, both natural and anthropogenic, observed in the last century are considered. It is shown that it is the increase in temperature that causes the increase in the concentrations of carbon dioxide and methane in the atmosphere, and not vice versa, as follows from the greenhouse effect hypothesis. This seems to be the main cause for the low effectiveness of any international efforts to stabilize the climate. The course of natural processes, as well as the evolution of the biosphere as a whole, has an unstable, cyclical nature, running according to its own laws. Particular attention is paid to V.I. Vernadsky’s doctrine of the biosphere, his views on the role of reason and scientific research in solving problems inevitably arisen in the course of evolution on Earth, caused by the rapidly developing, from a historical standpoint, humanity. Scientific research is a reliable defender of both the interests of mankind and the biosphere as a whole. This was V.I. Vernadsky’s basis of his positive outlook on the future of our civilization and the biosphere.
V.I. Vernadsky: Living matter is a geological concept
Having started his biogeochemical studies in 1916, V.I. Vernadsky revealed that the generally accepted opinion about the origin of life from inert matter had no scientific sources. But all data of biology and paleontology indicate that all life comes from life (Francesco Redi’s principle). Vernadsky found convincing evidence of biogenesis in the state of biological space–time, which allowed him to describe the biosphere as a planetary shell, actually forming other geospheres. Vernadsky’s concept of the planetary role of living matter is currently gaining overriding and fundamental importance for all Earth sciences.
Long-term dynamics of metal concentrations in river suspended matter (Oka River, 1983–2018)
Distribution features of cadmium, lead, partly Ag, Bi, In, Hg and Tl in suspended solids are considered. Studies were made on the Oka River in the area of the Prioksko-Terrasny Natural Biosphere Reserve on a river section remote from the zone of formation of the technogenic scattering stream, in the period 1983–2018. To assess the general trend of changes in the concentration of the elements over the period of the experiment, it was proposed to consider the results on their prevalence in the composition of suspended matter obtained in the intermediate hydrological phase of the river between the spring flood and the summer midden. This is the main feature and essence of our proposed approach in order to eliminate the influence of significant seasonal changes in the macro- and micro-component composition of suspensions. It is shown that the 35-year time interval can be divided into two periods, namely: the first one is characterized by a decrease in the concentration of heavy metals (Cd, Pb), while the second one is characterized by the absence of any trend, relatively weak fluctuations in values. The direction of changes in the concentration of elements in the first period correlates with the literature data on the dynamics of a decrease in the intake of anthropogenic wastewater into surface waters in recent decades and with the results of our assessment of the decrease in river water pollution upstream from the experimental area.
Thermal pollution as a significant anthropogenic contribution to global warming
This article examines the anthropogenic contribution to the planet’s climate system due to thermal pollution. Despite the quantitative predominance of solar and geothermal energy in the Earth’s heat balance, anthropogenic heat impacts the planet’s most sensitive shell – the biosphere. Thermal pollution in various countries has been assessed based on specific (per unit area) energy consumption, as all energy consumed by humanity is ultimately converted into heat and released into the biosphere. Specific carbon dioxide emissions also serve as an indirect indicator (marker) of thermal pollution, as fossil fuels remain the primary energy source. Calculated correlation coefficients between thermal pollution indicators (specific energy consumption and CO2 emissions) and climate warming in various regions have revealed a low positive correlation between these indicators (0.17–0.13, respectively), which indicates thermal pollution’s contribution to global warming to be still insignificant. Thus, the current contribution of anthropogenic heat to the climate system is primarily regional, which is undoubtedly important to consider in environmental policy to prevent the negative impact of this factor on the functioning of natural ecosystems. This is especially important in the context of global warming, primarily caused by natural factors.
On the prevalence of background and technogenically dependent concentrations of heavy metals in river waters
Features of the prevalence of Cd and Pb dissolved forms in the water of sections of the Oka river and other rivers of the Russian Plain are considered. The influence of anthropogenic wastewater (industrial, municipal and agricultural) containing heavy metals is clearly manifested only in certain sections of the rivers of central Russia (Oka River, Volga River, and Moscow River) against the background of natural landscape and geochemical processes. An attempt is made to develop approaches to assessing the degree of anthropogenic influence on the water composition of various river sections, including those remote from pollution zones. An ecological and geochemical lead–cadmium indicator is proposed, which makes it possible to assess the anthropogenic impact and divide river sections into 3 categories (strong, medium and weak pollution, respectively). The river sections with low anthropogenic pollution have high values of this indicator corresponding to waters with the background (or close to background) concentration. A decrease in the indicator values means an increase in the role of anthropogenic effluents in the water composition, and estimates of the average concentrations of elements are technogenically dependent.

ACCELERATION OF BOTH BIOTIC AND TECTONIC EVOLUTIONS: DOES BIOTA MODULATE TECTONICS?
The old hypothesis by Academician V.I. Vernadsky of the biosphere being a geological force to build the surface and immediate interior of our planet is indirectly supported based on statistical data. According to occurrence data on findings of all known animal specimens and according to some characteristics of the tectonic activity of the Earth, the presence of several previously unknown cycles shortening from cycle to cycle (approx. By a factor of 1.51) over about a billion years, is substantiated. This leads to an idea of a cause-and-effect relationship between these two different categories of cycles. The influence of tectonics on biota, to one degree or another, has long been known. However, due to the mentioned cycles being rather accelerated, it is difficult to imagine that such strong acceleration in the tectonic cycles could arise due to some intra-tectonic causes, whereas the accelerated nature of biotic evolution due to some intrabiotic causes is quite possible. So, a conclusion arises of the mentioned contracting tectonic cycles being modulated by biota. Possible mechanisms of such influence are hypothesized, their clarification requiring additional research. This conclusion is revolutionary for geology and reveals biotic evolution’s previously unknown role as an active creator of global tectonic (cyclic) processes at a new, quantitative level, which is also revolutionary for evolutionary biology. But, regardless of these conclusions, the mentioned decreasing cyclicity is of interest itself, for the first time (statistically) speaking about the accelerated nature of evolution over such vast time periods.
LOW-CARBON POWER AND GLOBAL CLIMATE WARMING
The problem of global climate warming and attempts to solve it, including using low-carbon power engineering, are analyzed. The success of solving this problem depends on the degree of understanding of the processes which cause it. As more and more data speak about natural causes of climate fluctuations, and of anthropogenic factors the greatest contribution to the warming is made by thermal pollution rather than the anthropogenic growth of carbon dioxide in the atmosphere, low-carbon power, with all its positive qualities, is unable to solve the problem of climate warming.
