Methods of CO2 separation from air, ways of its use and long-term storage
Kober, Ondřej ; Baláš, Marek (referee) ; Škorpík, Jiří (advisor)
Combustion of fossil fuels creates greenhouse gas emissions that cause global warming. The most important of these gases is carbon dioxide. Although it occurs naturally in the atmosphere, human emissions upset the balance of various natural processes. The aim of this bachelor’s thesis is to conduct a background research in the field of carbon dioxide capture, storage and utilization. The thesis also describes the role of carbon dioxide in the atmosphere, its cycle and human influence on carbon dioxide concentration.

Separation and storage of CO2
Odložilík, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The main objective of this work is to clarify the methods for CO2 capture and storage as an option to limit global warming. The first part is further explained by a phenomenon known as the greenhouse effect, there is illustrated his principle, the effects of climate change, the main factors increasing its intensity and its possible reduction. Framework of the second part is description of the technologies and methods of CO2 capture and storage, the individual steps in these processes and also the possible development in the future. Next chapter discusses the pilot research programs and application of referred technologies to in practice. The last part of this work is devoted to the economical aspect of the problems.

Aviation impact on global warming
Štarha, Adam ; Juračka, Jaroslav (referee) ; Zikmund, Pavel (advisor)
This bachelor‘s thesis deals with the issue of ever-increasing aviation emissions. It describes where greenhouse gases appear and what their excessive amount causes. Furthermore, this work deals with the comparison of emissions of individual modes of transport and the comparison of the benefits of individual modes of transport, especially air transport, through subsidies and tax relief in the EU.

Determination of carbon footprint in relation to the production unit of the budget indicator
Šebestová, Michaela ; Kocourková, Gabriela (referee) ; Krejza, Zdeněk (advisor)
The presented diploma thesis analyses the possibilities of determining the carbon footprint in relation to the production unit of the budget indicator. The theoretical part of the thesis describes the basic concepts associated with the carbon footprint and construction industry. The aim of this thesis is to quantify the carbon footprint of construction process, mainly during the production phase, and to compare the carbon footprint of objects of different production technology. The main output is the determination of an average carbon footprint converted to a unit of the budget indicator.

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.

Thermal radiation in real life
Kalus, Petr ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
This bachelor's thesis deals with the impact of heat transfer by radiation on the life around us. The research part summarizes the fundamental laws and concepts necessary for understanding the given issue. Furthermore, it describes and analyzes phenomena in everyday life where radiation is dominant. The greatest attention has been devoted to solar radiation, followed by the greenhouse effect, along with its influence on global warming. The thesis also includes a procedure for calculating heat transfer by radiation between two surfaces, based on which a Python script was written. Subsequently, a standalone application with a graphical interface was developed. The conclusion of the thesis focuses on describing the software development process and provides examples of test cases in thermomechanics.

Geoengineering as a solution to climate change
Pól, Daniel ; Elcner, Jakub (referee) ; Lízal, František (advisor)
The bachelor thesis contains short summary of current knowledge about the geoengineering methods. The research includes their history and all experiments made so far and describes the behaviour and potential utilization of aerosols in the atmosphere. Following chapters characterize four main methods of active geoengineering together with evaluation of their advantages and disadvantages. The last part of the thesis is devoted to the geopolitical impacts of geoengineering activities on society.

How will a longer vegetative season affect carbon sequestration in plant biomass
Kasperová, Denisa ; Albrechtová, Jana (advisor) ; Ponert, Jan (referee)
As a result of human activity, a large number of greenhouse gases, especially CO2, is released into the atmosphere, which causes a greater greenhouse effect and an increase in the temperature of the surface of the planet and the air in the atmosphere. Ongoing climate change is one of the great challenges facing society, as rising temperatures on the planet greatly affect the functioning of its ecosystems. Extremes arising from climate change, especially temperature rise and lack of precipitation or a change in the annual distribution of precipitation, affect the physiology and phenology of plants. Higher temperatures cause plant growing seasons to shift and lengthen, which has a direct impact on the sequestration of carbon in plant biomass through a biochemical, physiological plant process called photosynthesis. The increase in CO2 concentration in the atmosphere is slowed down by terrestrial forest ecosystems, as they can retain carbon in their tissues, especially in wood, for a relatively long time before it returns to the atmosphere. However, the efficiency of binding carbon into biomass also depends on other physiological processes, e.g., photorespiration, breathing, gas exchange between the plant and the atmosphere. Stressors caused by climate change can then limit growth, photosynthesis,...
