The negative effects of global climate change and the impact of rising surface air temperatures are already evident. Among the many echoes of these processes are the melting of glaciers, the reduction of the ice cover of the northern seas, the gradual disappearance of permafrost, sea level rise, soil erosion, and extreme weather events such as floods, hurricanes, droughts, and forest fires. As a result, the world's freshwater resources, public health and the well-being of the environment are under threat. Annually renewable fresh water resources, represented by the annual flow of rivers, are of undoubted value. Our goal was to identify the relationship of meteorological parameters, such as surface air temperature and precipitation in the high-altitude region of the Central Caucasus, with water consumption in the lowland territory of the Caucasus on the example of the river.Terek (art. Kotlyarevskaya). These studies are particularly valuable from the point of view of the relationship between climate change and its further impact on the hydrological cycle of the lowland regions of the Caucasus. In the course of the research, the relationship was revealed, indicating that the distribution of river flow over the territory of the Caucasus corresponds to the distribution of the annual amounts of surface air temperature and the annual amounts of atmospheric precipitation.

Miyun reservoir is a surface water source of the city of Beijing. This paper explores the relationship between reservoir basin runoff and climate change. Statistical analyses are employed to analyze the variations in rainfall, air temperature, and runoff in the reservoir basin. Results show uneven inter-annual variability in rainfall data series. Air temperature show a rising trend with 1993 and 1994 being the two significant mutation years. Runoff has been decreasing over the years. Based one inter-annual analysis, July and August had the largest runoff. Elastic analysis shows no significant relationship between rainfall and runoff.

Background. Recently, more and more attention has been paid to the study of plant phenology in the context of the global climate change. By now, the question of how climate factors affect the phenophases of plants has not yet been fully investigated. Accurate forecasts for biological responses of plant species to climate change require profound understanding of the impact produced by meteorological factors on plant phenology.Materials and methods. The research was targeted at Astragalus L. spp. introduced into the dry steppe areas of the Kulunda Plain. Meteorological indicators were selected for agrometeorological description of the plant introduction site to assess its hydrothermal conditions. The Pearson correlation coefficient was used to identify the level of correlations between the studied parameters.Results. High air temperature shortened the growing season of Astragalus cicer L., but lengthened its flowering and fruiting phases. An increase in relative air humidity shortened the flowering in A. cicer. Meteorological indicators did not significantly affect the duration of the phenophases in A. sulcatus L. For A. onobrychis L., an increase in the average relative humidity reduced the budding phase, while an increase in the average and maximum air temperature and an increase in the amount of precipitation increased the flowering period. A decrease in air temperature and average relative humidity, and an increase in the total precipitation lengthened the duration of fruiting in A. onobrychis. Increased average temperature and humidity reduced its fruiting phase.Conclusion. A. sulcatus is tolerant to the dry steppe environments. The phenophases of A. cicer and A. onobrychis are more responsive to changes in meteorological indicators. In A. onobrychis, the fruiting phase is susceptible to the combined impact of climate factors. The limiting factors for A. cicer are relative humidity, total precipitation and mean temperature during the growing season.

Abstract The aim of the work is to characterize the trends of sunshine duration (SDU) and air temperature, which may help understand the mechanism of contemporary climate change and explain its causes. The daily totals of SDU and daily data on air temperature from the years 1971–2019, from 25 synoptic stations in Poland are the basic source data. There was a growing trend in both SDU and air temperature. The series of records of the two variables showed that the points of change in the level of stabilization of the value of SDU and air temperature are close to each other, and confirm known in the literature “global dimming” and “global brightening” periods. The linear regression model confirmed that sunshine duration explains well the variability of, and increase in day-time air temperature in Poland in the April-September period. In turn, changes in sunshine duration during winter have no impact on air temperature trends.

The earth's climate is constantly changing, it's just that climate change in the past took place naturally. But until now, climate change has been very closely related to human activity, so the nature of the event has become faster and more drastic. Relative humidity is a parameter that can affect climate change in Indonesia, especially in Aceh Province. Aceh province is one of the provinces located on the island of Sumatra and directly facing the Indian Ocean. Thus, Aceh Province has a considerable impact on climate change. Changes in relative humidity will lead to changes in climate elements. There are several climate elements including air temperature, rainfall, sea surface temperature, wind speed, solar radiation, and dynamic altitude. One of the methods used to look at the relationship of each climate element is the Correlation method. The purpose of this study is to find out the relationship of each variable of the climate elements. The results showed that the relationship between variables X1 (air temperature) and X3 (sea surface temperature) had the highest closeness relationship with a positive correlation value of 0.77. The lowest closeness relationships are variables X2 (rainfall) and X4 (wind speed) with a negative weak correlation value of -0.01.

Climate change and its impact on water resources is the problem of the times. Therefore, this study is concerned with the subject of climate change and its impact on the water ration of the grape harvest in Diyala Governorate. The study was based on the data of the Khanaqin climate station for the period 1973-2017, (1986-2017) due to lack of data at governorate level. The general trend of the elements of the climate and its effect on the water formula was extracted. The equation of change was extracted for the duration of the study. The statistical analysis was also used between the elements of the climate (actual brightness, normal temperature, micro and maximum degrees Celsius, wind speed m / s, relative humidity% The results of the statistical analysis confirm that the water ration for the study area is based mainly on the X7 evaporation / netting variable, which is affected by a set of independent variables X1 Solar Brightness X4 X5 Extreme Temperature Wind Speed ​​3X Minimal Temperature and Very High Level .

The article deals with the problem of achieving sustainable development. The purpose of this study is to reveal the relationship between the components of sustainable development, taking into account the involvement of indigenous peoples in nature conservation. Climate change makes achieving sustainable development more difficult. Indigenous peoples are the first to feel the effects of climate change and play an important role in the environmental monitoring of their places of residence. The natural environment is the basis of life for indigenous peoples, and biological resources are the main source of food security. In the future, the importance of bioresources will increase, which is why economic development cannot be considered independently. It is assumed that the components of resilience are interrelated and influence each other. To identify this relationship, a model for the correlation of sustainable development components was developed. The model is based on the methods of correlation analysis and allows to determine the tightness of the relationship between economic development and its ecological footprint in the face of climate change. The correlation model was tested on the statistical materials of state reports on the environmental situation in the Khanty-Mansiysk Autonomous Okrug – Yugra. The approbation revealed a strong positive relationship between two components of sustainable development of the region: economy and ecology.

This chapter focuses on the connection between the international legal framework governing the conservation of natural resources and human rights law. The objective is to examine the potential synergies between international environmental law and human rights when it comes to the protection of natural resources. To do so, it concentrates on three main areas of potential convergence. It first focuses on the pollution of natural resources and analyses how human rights law offers a potential platform to seek remedies for the victims of pollution. It next concentrates on the conservation of natural resources, particularly on the interconnection between protected areas, biodiversity, and human rights law. Finally, it examines the relationship between climate change and human rights law, focusing on the role that human rights law can play in the development of the current climate change adaptation and mitigation frameworks.

This chapter discusses the emergence of environmental history, which developed in the context of the environmental concerns that began in the 1960s with worries about local industrial pollution, but which has since evolved into a full-scale global crisis of climate change. Environmental history is ‘the history of the relationship between human societies and the rest of nature’. It includes three chief areas of inquiry: the study of material environmental history, political and policy-related environmental history, and a form of environmental history which concerns what humans have thought, believed, written, and more rarely, painted, sculpted, sung, or danced that deals with the relationship between society and nature. Since 1980, environmental history has come to flourish in many corners of the world, and scholars everywhere have found models, approaches, and perspectives rather different from those developed for the US context.
