Water Management Analysis of Reservoir Storage Capacity Due to Climate Change
Šenková, Monika ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The aim of this work is a water management solution of the storage volume of the Vlachovice reservoir in the conditions of climate change. Due to the long-term drought and flood period, the Czech Republic decided to build multi-purpose reservoirs. One of them is the multi-purpose water reservoir Vlachovice. The tanks are designed for a certain storage volume, which is calculated from the flow series in a given water profile. Flows on watercourses are conditioned by climatic and geomorphological conditions. Climatic conditions are constantly changing and significantly affect flows. It is difficult to determine the future of water flows. Future flows are generated based on measured values ??and expected climate change using mathematical models. In this work, just these two scenarios of the future of flow series depending on the amount of precipitation and temperature changes are compared.

Kührová, Kateřina ; Němcová, Miroslava Pumprlová (referee) ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
Submitted bachelor thesis deals with adaptations of the urban environment to climate change, with special focus on adaptation strategies using greenery as the element of positive influence on the urban environment. The thesis is divided into two sections. In the first section the problematic of climate change and its effects and consequences for the urban environment is introduced, using both domestic and foreign sources. Scientific findings and adaptation options are listed with some examples of applied adaptation measures. The psychological effect on the city population is also considered as also a sociological research was conducted. The second part deals with analysis of the impact of two adaptation measures, both realized in the city of Brno – the existing green roof in Otevřená zahrada at Obilní trh and the City Cell Prototype – the temporary installation realised on Malinovského náměstí. The temperature and humidity data collected in the reference period (August – October/September – October 2018) are analysed together with the data recorded by meteorological station of the Institute of Landscape Water Management at the Brno University of Technology – Faculty of Civil Engineering.

Abrupt cooling events in the Late Glacial and the Early Holocene
Švanda, Petr ; Vondrák, Daniel (advisor) ; Tichá, Anna (referee)
This bachelor thesis is prepared in the form of a literature review focused on abrupt cooling events in the Late Glacial Interstadial and the Early Holocene (14 700 to 8 200 cal. BP). The aim was to summarize the scientific knowledge on six such climate fluctuations and their causes and consequences. All of these events (GI-1d, GI-1c2, GI-1b, 11 400 event, 9 300 evenet, 8 200 event) lasted more than 50 years and are followed by cooling of more than 1 řC. Literature sources on this topic are based on interdisciplinary studies of various natural archives and the interpretation of so-called proxy data. For each climatic event, an assessment of its effects on ecosystems and human societies at the time was also made. The above findings are finally discussed in the context of the current climate change issues and the possible future of weakening the Atlantic Meridional Overturnig Circulation.

Quaternary climate changes: Analysis of the primary/secondary and high school textbooks
HAVLÍKOVÁ, Adriana
The bachelor's thesis deals with climatic changes in the Quaternary and its content in natural history, geography, and history textbooks for elementary and high schools. In the first part, we learn about the basic terms for a better understanding of the issue. Furthermore, both natural and anthropogenic causes, consequences, and development of climate changes in history from prehistoric times to the present. The second part of the thesis focuses on the analysis of the topic of climate change in textbooks. The results are summarized in a clear table. The main goal of the work was to analyse the information that are obtained in the textbooks to evaluate whether the topics which, are contained in the textbooks, are sufficient for students for fully understanding. At the end, a worksheet for the 9th grade of elementary school was created as a supplemental curriculum, which is intended to help with the correct understanding of the topic of climate change and to avoid misinterpretations.

Application of the principles of rainwater management during the revitalization of the former industrial area
Záchenská, Lívia ; Balasová, Kateřina (referee) ; Ručka, Jan (advisor)
This bachelor's thesis examines rainwater management in an urban intravillan, focusing on the revitalization of a former industrial brownfield in Brno. The study analyses the challenges associated with rainwater management and proposes an economical solution that benefits both citizens and the environment. The introduction provides insights into water management, including consumption, climate change, sewer line overloading, greywater utilization, and environmental impacts. The theoretical section explores the profitability of brownfield revitalization, incorporating an analysis of the former industrial area. Based on this analysis, a renewal plan for the brownfield is developed. The practical part introduces specific rainwater management facilities, addressing legislation and mathematical considerations. The brownfield is divided into sections, and the implementation of rainwater management facilities is proposed for each section. The facilities are accompanied by calculated charts and graphics for better visualization. This thesis contributes to the field of rainwater management in urban intravillan areas by presenting a practical approach to address the challenges associated with rainwater in a former industrial brownfield. The proposed economical solution aims to enhance citizen well-being and promote environmental sustainability.

Climate change and information overload
Pittner, Jan ; Miessler, Jan (advisor) ; Soukup, Martin (referee)
This bachelor's thesis focuses on the topic of information overload and climate change. The theoretical framework presents information overload as a concept in general and then in the context of climate change. It specifies how information overload can arise in terms of consumption of different media types and mentions symptoms and potential impacts of the problem. It focuses on groups of recipients of climate change information. These groups are those who experience climate change directly and those who learn about it indirectly. It focuses on fake news about climate change and ways of their misuse. It also provides a discussion on potential solutions of the problem of information overload which appear in literature as guidelines and recommendations at individual, media organizations and workplace levels. The practical part of the thesis uses a questionnaire survey to obtain specific data and then quantitatively analyses it. The collected data is divided into categories which are compared with each other using graphs and charts. The findings are placed in the context of current knowledge summarized in the theoretical framework. The main finding of this survey is that there is a positive correlation between the respondents' level of information overload and ability to act. Other findings are that...

Reakce sazenic břízy bělokoré (Betula pendula Roth.) na stres suchem
Orlovský, Vít
Climate change, with its accelerating intensity, is the primary factor to which forest and urban stands need to respond. Particularly more frequently, recurrent periods of drought, coupled with rising average annual temperatures, mainly in urban development, represent a significant plant stressor. As silver birch (Betula Pendula Roth) is a frequently used tree in urban plantings, the aim of this work was to assess the physiological response of silver birch seedlings after the completed leaf development to stress by drought. Evaluation of the response of the seedlings to stress confirmed the assumption that water potential decreases as the drought increases. Due to the stress of the drought, we saw an 86% decrease in water potential measured at noon compared to the beginning of the experiment. From the results of a 17-day experiment, we found that stress from drought caused a 96% decrease in the rate of photosynthesis and stomatal conductance. So birch seedlings reacted very sensitively to drought stress by trying to avoid reducing water potential. When comparing the variability of the responses of individual seedlings, the physiological parameters showed a marked difference in their response to stress by drought. For example, for rate of photosynthesis, the coefficient of variation for stressed seedlings reached 97% at the end of the experiment. The PRI reflectance index, which indirectly characterises the carotenoid content, showed a coefficient of variation of even 306%. All this information provides us with clear evidence of the ability of individual birch seedlings to react to drought stress in a different way. Based on our measurements and subsequent results, we can conclude that the variability of silver birch seed material is able to respond to the demands implied by the projected climate change.

Niche width of eukaryotic marine phytoplankton with respect to recent and future climate change.
Junková, Natálie ; Kulichová, Jana (advisor) ; Neustupa, Jiří (referee)
This paper describes the concept of niche breadth of photoautotrophic protists and attempts to introduce us to the basic concepts we may encounter when studying the ecological niche. The review clarifies what a niche is and its components fundamental and realized niche and presents some examples of organisms that are specialists or generalists. It uses diatoms, dinoflagellates and Haptophytes to describe how they can be affected by climate change. Since the number of environmental changes is steadily increasing, it is very difficult to predict the changes in the coexistence of generalists and specialists. The thesis presents some of the main methods used in measuring the width of the ecological niche of protists, which can be MaxEnt, ONE and the most frequently mentioned OMI (outlying mean index) method, which is described in more detail in the thesis. Given the focus of the thesis on photoautotrophic marine plankton, the most frequently mentioned organisms are diatoms, dinoflagellates and Haptophyta. Finally, I summarize the main ocean factors that could be affected by climate change, which are mainly pH, temperature, salinity or the amount of available nutrients (carbon, nitrogen, phosphorus, silicon and iron).
