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.

Development of the Carbon Footprint of the Czech Republic since 1989
POJMANOVÁ, Lucie
The thesis is focused on the development of the carbon footprint in the Czech Republic. The object is to determine the causes referring to the changes in greenhouse gas emissions. The comparison of the dynamic of greenhouse gases with the changes in indicators such as gross domestic product, legislation, economics and technology are researched. I compared the development of two indicators - the growth of the carbon footprint and the growth of GDP. Correlation analysis was done and it has been shown that there is a decoupling of economic growth from negative environmental impacts. Then I examined the changes in policy after 1989, which had an impact on this issue. Another important aspect was the entry into the European Union, which brought many changes and important legislation in the environmental field.

Increase in Winter Air Temperatures in the Czech Republic between 1961 and 2010
Střeštík, Jaroslav ; Rožnovský, J. ; Štěpánek, Petr ; Zahradníček, Pavel
Based on the analysis of average monthly air temperatures between 1961 and 2010 it can be statistically proven that there is an increasing trend. The actual level of increase, however, is different for each season and is also specific for a particular region – there are differences between Bohemia and Moravia. In the summer, the average monthly air temperatures rise more significantly in Moravia, where there is a higher number of stations with increase of over 1°C compared to Bohemia. This is also true for the spring, for which the difference is not so profound, and is yet smaller in the autumn. In contrast, in the winter there is a more significant increase in Bohemia, where most stations show an increase of over 0.5°C. In Moravia the increase is usually only around 0.3 to 0.4°C. Differences between the increases of average air temperature can also be seen across the individual winter months. Highest increase was found in January, where some stations in Bohemia show an increase of over 1°C, a value that was not observed in Moravia, where some stations have an increase of less than 0.8°C. In December and February, the level of increase in general is much smaller. However, given the predicted increase of air temperatures in the future in general, it can be expected that in the upcoming decades the number of warm winters will increase. Such increase of air temperatures in the winter is likely to have negative impacts for the agriculture.

Genetically modified plants for future of globally warmed planet
Nedělová, Jana ; Opatrný, Zdeněk (advisor) ; Nátr, Lubomír (referee)
Many problems which have an adverse impact on crops, come into the agriculture with global warming the planet and thus changes in regional temperature and humidity regimes. These problems will be significant especially in developing countries that are already interfered by drought and threatened by famine. Therefore major target is developing of plants resistant to these climatic changes. Only the very classical breeding doesn't clearly sufficient for these tasks. However, genetic engineering could contribute significantly by genetically modified (GM) plants. This modern breeding-cultivation technology has several advantages in comparison with traditional breeding. One of them is for example targeted and well-controlled change in genotype, which allows obtaining plants with specific desired properties.

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.

The temperature and precipitation course in Prague-Karlov, 1961-2010
Střeštík, Jaroslav
The course of temperatures and precipitation in Prague over the last 50 years is presented and compared with scenarios of the further development of the climate. The temperature increased significantly and this increase is more rapid than that of the global temperature. Precipitation totals display only very small decrease over the last 50 years. However, precipitation totals in spring decreased more than the annual sums and a remarkable decrease of days with heavy rainfall takes place. These facts contribute to the observed decrease of the amount of moisture in nature and to the increased occurrence of droughts. There is no indication that all these observed trends could be different in future.

The change of mean air temperatures i the town and outside the town during the last 65 years
Střeštík, Jaroslav
The climate in the town differs from that in the nearest surroundings in many respects: in the town higher air temperature. lower air humidity, much higher air pollution et. takes place. The town can be considered as an island with a different environment. Due to the increase of towns all mentioned differences between the town and its surroundings increase too. In this contribution the change of mean annual, and seasonal air temperature in the Prgue center (Klementinum) and on its boundary (airport Ruzyně) during 1946-2009, partly on airports Tuřany and Mošnov during 1951-2009, will be presented. Mean air temperatures on all stations display, besides a considerable fluctuation, a stable increase given by the global warming.

Political vision of Vaclav Klaus
Binar, Martin ; Rataj, Jan (advisor) ; Prorok, Vladimír (referee)
This bachelor thesis deals with opinions of Vaclav Klaus, which are compared with teoretical basics of liberalism and conservatism. The main goal is to point out Klaus'es values according to both ideologies. First part of thesis describes main values of liberalism and conservatism in theoretical way, which are then compared with Klaus'es opinions in main events of his political career. Second part describe those events. To 2003 was Klas in institutional function as finance minister and prime minister, so this event are from this point of view. In 2003 was Klaus elected to the highest institutional function - president of Czech republic. So th third part describes his opinion of European union and global worming as president.
