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.

Comparison of life-cycle emission produced by cars
Plott, Patrik ; Ušiak, Michal (referee) ; Fridrichová, Kateřina (advisor)
This bachelor´s thesis of research nature deals with comparison of emissions of individual types of passenger car´s powertrains in terms of their entire life cycle. The goal was to describe current emission regulations of passenger vehicles, various types of power units they use, and emissions that are created in manufacturing, using and disposal of these vehicles. The comparison includes not only different types of internal combustion engine vehicles, but also electric vehicles. In conclusion were these power units evaluated based on emission considering current situation.

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.

Design of a Houseboat
Csadiová, Dominika ; Chorý, Tomáš (referee) ; Křenek, Ladislav (advisor)
The topic of the master thesis is the design of a floating house. Product responds to the current global problems, especially the consequences of global warming and population growth. Rising sea levels are a factor that negatively affects several areas, mainly cities near the coastline. In combination with population growth, the possibility of moving dwellings to the water surface can be an attractive solution. The master thesis also aims at environmental friendliness, emission reduction and the use of alternative energy sources. Nowdays, houseboats on the water are very popular, but are mostly used only for recreation. The master thesis presents a design of a floating house for year-round living on the seas and oceans for 2 to 3 people.

Optimisation of the house heating by use of the renewable energy sources
Husák, Ondřej ; Frk, Martin (referee) ; Křivík, Petr (advisor)
The thesis contains is familiar with the issues of renewable energy and global warming. Assessing the use of these resources in households in the Czech Republic. The selected family house, perform measurements on the existing heating system. In conclusion, there is suggestions for optimalization system houses, the possibility of linking the with renewable energy sources and an assessment of economic turn.

Cycling Mechanism/Linguistic Fluidity
Dlabaja, Martin ; Lungová, Barbora (referee) ; Sterec, Pavel (advisor)
The main purpose of this work is to show relative scales of temperature changes during holocene and pleistocene [1.] using evaluated combined data sets from Greenland Ice Core Project and Vostok Ice Core project [2.]. Projects are researching values of CO2 in atmosphere using deep drills into sedimentary ice sheet layers corresponding in its maximum depth (approx. 3 km) to 800 kyr BP [3.] Values of CO2 correlates with temperature [4.]. Then we can lay out different cultural peak events on weather background and analyze the influence of temperature changes on rise and fall of empires, (Mesopotamia, Egypt, Shang, Indus, Rome) or study dramatic extinction events (Younger Dryas), watch the very beginning of culture in Fertile Crescent to witch trials in european “dark ages” in very close and evident correlation to weather change. Second goal is introduction to perceiving deep time as such.Third would be to raise questions and discussion about our own supposedly rigid timeline given to us by archeology by purposefully picked events such as meltwater pulses in Younger Dryas. (Lost cultures in Younger Dryas? Boloid impacts? Immediate emergence of writing systems without any proto evidence?) Of course a point of this work I didn’t mention is to present scientific data in aesthetically pleasing and effective way. These researches can be really “mind-blowing” if presented thoughtfully, (here in a way that is both attractive and shows scales and impact on our present day in a context of a global warming), but stays hidden from common knowledge due to for some “sterile” presentation in data sheets, which can be hard to read and make sense out of for people missing context.

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.
