The main goal of this study was to obtain the attribution results of a physical assessment of the modern hydrological consequences of separately natural and anthropogenic components of climate change, based on the synthesis of detailed process-based models of river runoff formation and an ensemble of Earth system models (ESMs) within the large river basins in Eastern Siberia. This approach allows calculating the river flow using ESM-based data over the observation period under two scenarios, considering: (1) the anthropogenic impact of increasing greenhouse gas emissions and (2) only internal fluctuations of the climate system and natural external forcing. According to the results of the numerical experiments, the attributions of anthropogenic components of climate change in the dynamics of the Lena runoff are weak, i.e., during the observation period, the Lena River flow statistically significantly increases, but it occurs mainly due to natural climate variability. The changes in the Selenga runoff are intensely influenced by the anthropogenic component of climate change. Since the 1970s, the Selenga runoff increased under natural climatic conditions, but since the mid-1980s, it decreased under anthropogenic greenhouse gas emissions, due to reduced summer precipitation. This was the main reason for the last low-water period of 1996–2017 in the Selenga basin.

Aim. Proper development of animal breeding in the conditions of current global problems and the decrease of anthropogenic burden on environment due to greenhouse gas emissions, caused by animal breeding activity, require the study of interaction processes between animal breeding and external climatic conditions. Methods. The theoretical substantiation of the problem was performed based on scientifi c literature, statistical informa- tion of the UN Food and Agriculture Organization and the data of the National greenhouse gas emissions inventory in Ukraine. Theoretically possible emissions of greenhouse gases into atmosphere due to animal breeding in Ukraine and specifi c farms are calculated by the international methods using the statistical infor- mation about animal breeding in Ukraine and the economic-technological information of the activity of the investigated farms. Results. The interaction between the animal breeding production and weather-and-climate conditions of environment was analyzed. Possible vectors of activity for the industry, which promote global warming and negative processes, related to it, were determined. The main factors, affecting the formation of greenhouse gases from the activity of enterprises, aimed at animal breeding production, were characterized. Literature data, statistical data and calculations were used to analyze the role of animal breeding in the green- house gas emissions in global and national framework as well as at the level of specifi c farms with the consid- eration of individual specifi cities of these farms. Conclusions. Current global problems require clear balance between constant development of sustainable animal breeding and the decrease of the carbon footprint due to the activity of animal breeding.

<p><b>Abstract </b></p> <p>While the pedagogical benefits of fieldtrips have long been recognised our ever increasing understanding of the impacts of flying on climate change is presenting educators with a poignant dilemma; the many benefits long associated with international fieldtrips are at odds with the world community’s needs in limiting/halting climatic change. In response, the paper presents the concept of a VR-based virtual fieldtrip as an innovative and carbon-sensitive type of (educational) travel. The paper not only makes the case for virtual fieldtrips as a meaningful learning tool but also explores both the virtual fieldtrip’s impact on Greenhouse Gas emissions and climate change-related learning. On both accounts the initial findings in this paper are very encouraging. More in-depth research is now required to not only develop a deeper understanding of the full breadth of benefits, but also of the diverse weaknesses presented by virtual fieldtrips and how to negotiate them.</p>

Objective – This paper sets out to assess perceptions of food retailers regarding climate change, greenhouse gas emission and sustainability in the Nelson Mandela Bay region of South Africa. The primary objective of this study is to investigate the food retailers’ greenhouse gas emissions strategies. Climate change catastrophic potential and the harmful effect that it has had on the community and businesses has led to it being given attention from social media and in literature. Methodology/Technique – This paper covered a literature review that provided the theoretical framework. The empirical study that was carried out included self-administered questionnaires which were distributed to 120 food retailers who were selected from the population using convenience sampling. Findings - The results revealed that most of the respondents were neutral towards the impact of operational factors regarding GHG emission in the food retail sector. Novelty - There is limited research that has been conducted among food retailers from the designated population. The study provided guidelines that will be of assistance to food retailers when dealing with climate change and greenhouse gas emissions impact in the food retail sector. Type of Paper: Empirical.

Waste management has an influence on the greenhouse gas (GHG) formation. The emissions of greenhouse gases vary between the EU countries depending on waste treatment practices and other regional factors such us composition of waste. The aim of this paper was to examine, from a life-cycle perspective, Municipal Solid Waste (MSW) management in the context of greenhouse gas formation and to evaluate the possible reduction of climate change potential of alternative waste management options in Estonia. The paper summarises the results of a case study in Estonia, assessing the climate change impact by 2020 in terms of net greenhouse gas emissions from two possible management scenarios. As a result it can be concluded that better management of municipal waste and diversion of municipal waste away from landfills could significantly reduce the emissions of GHG and, if high rates of recycling and incineration with energy recovery are attained, the net greenhouse gas emissions may even become negative. It means that these waste management options can partly offset the emissions that occurred when the products were manufactured from virgin materials and energy was produced from fossil fuels. This is especially important concerning the climate change impact.

A crucial role in climate change adaptation is the one that should be played by cities. These are major contributors to climate change as well as most vulnerable to the effects of climate change. As urban population in cities increases, so does the greenhouse gas emissions. Urbanisation and the growth of cities continues at great speed, and today the global urban population has increased nine fold since 100 years ago. Though presented with current challenges and threats such as environmental degradation, urban poverty and food security, urban density could create a better quality of life and a lower carbon footprint by innovative approach and more efficient infrastructure planning. Creative solutions are implemented as part of the sustainability component of an integrated, climate resilient city, which comprises of fundamental aspects such as food, water, energy and transport. Application of local knowledge on agroforestry can be utilized in an urban setting, and has positive impacts on a microclimate scale, such as reduces impact of higher rainfall, reduction of greenhouse gas emissions and reduces vulnerability on the urban poor. Urban agroforestry largely contributes to sustainable urban food production opportunities, and encompasses four main fields of practice, including agroecology, urban forestry, urban agriculture and permaculture. This paper examines the local knowledge of agroforestry and how the local knowledge can be transferred into practice in an urban setting, thus providing a sustainable approach towards climate change adaptation in cities.
