Paleozoic glaciation as an analog for Quaternary glacial cycles?
Kubíček, Martin ; Laurin, Jiří (advisor) ; Laibl, Lukáš (referee)
This bachelor thesis is focused on the comparison of the two main glacial periods of the Phanerozoic, the Late Paleozoic Ice Age and the Cenozoic Ice Age including Pleistocene. The main goal of the thesis is to compare the factors of glaciation and their controlling mechanisms on short and long-term scales, and the basic features of the Earth's circulation. Last but not least, the evaluation of unresolved questions and consideration of the possibility of using data from the Cenozoic, which point to a very complex behaviour of the climate system components. In both periods compared, the main climate driver appears to be the atmospheric greenhouse gas content. Another common feature is the declining trend in temperature, manifested initially by a less significant and ephemeral glaciation during the Upper Devonian, Eocene and Oligocene. The transition to the coldest phases with the lowest average temperature and the largest ice volume is characteristic. Based on CO2 content, amplitude of glacioeustatic oscillations or Milankovitch cycles, a sequence of several glaciation events in the Serpukhovian to Sakmarian interval can be considered as an analogue of the Pleistocene. The difference from the Pleistocene glaciation is presence of a large number of glaciation centres in the Gondwana area. Some...

The long-term impact of energy poverty and its mitigation on educational attainment: evidence from China
Martirosyan, Yervand
Existing studies demonstrate the short-run connection between environmental conditions and academic performance. However, the long-term effects of exposure to adverse living conditions on academic achievement remain underexplored. This study investigates the long-term impact of energy poverty, and policy interventions aimed at alleviating it, on the academic performance of Chinese schoolchildren starting from infancy. It specifically utilizes the Huai River Policy, which provides free winter heating exclusively to northern regions in China but not to adjacent southern regions. My findings suggest a significant positive influence of winter heating on schoolchildren’s academic performance, with a more pronounced effect for children born during winter months. The insights gained from this research could inform policy debates to enhance educational outcomes and human well-being.\n

Modeling the impacts of combined climatic events on the growth, development and yield parameters of field thermophilic vegetables and oilseed rape in the decision support system in the field of agrotechnology transfer - DSSAT
Potopová, Vera ; Muntean, N. ; Chawdhery, M. ; Trifan, T. ; Zehnálek, P. ; Soukup, J. ; Potop, I. ; Zahradníček, Pavel ; Možný, Martin
Modeling the impacts of combined climate events on the growth, development and yield parameters of field thermophilic vegetables and oilseed rape in a decision support system in the field of agrotechnology transfer - DSSAT. This book will introduce you to the latest information technologies and their applications in agriculture, including decision support systems, crop simulation models and other computer tools. It should also help you to solve problems at the regional level on issues related to crop production and other issues related to agriculture, natural resource management and cropping systems and food security, as well as issues related to climate change and variability. This professional book offers users the appropriate supplementary material to enable them to continuously meet the demands of a changing climate. The book is divided into two parts, theoretical and practical. The theoretical part summarizes basic information about simulations of crop production, water and nutrient management, climate risks and environmental sustainability. In the practical part, the procedures for working in the DSSAT program (Decision Support System for Agrotechnology Transfer) are presented.

Monitoring the state of knowledge about climate change in geological history among high school students
MANOVÁ, Štěpánka
This bachelor's thesis focuses on the monitoring of knowledge of climate changes in geological history among high school students. The research was with the aim of mapping the knowledge of high school students. The assessment of knowledge was carried out by means of a questionnaire survey. The questionnaire was first created, then sent online and then evaluated. Data collection took place from January to March in 2022. This work has shown that the knowledge of climate changes in geological history is not very extensive among high school students due to lack of information in school and lack of interest in this topic.

Nonstationarity of the effects of modes of atmospheric circulation variability on surface climate elements
Hynčica, Martin ; Huth, Radan (advisor) ; Dobrovolný, Petr (referee) ; Beck, Christoph (referee)
Circulation modes are highly correlated, yet often distant areas detected in a field of a circulation variable, such as sea level pressure, geopotential heights, wind speed, and wind components. They consist typically of two or more action centres, which simultaneously weaken or strengthen, hence affecting the intensity and direction of atmospheric circulation and consequently surface climatic elements, such as temperature and precipitation. Temporal variability of action centres affects spatiotemporal distribution of impact on surface climatic variables. The availability of gridded datasets allows investigation of temporal behaviour of action centres and its impact on surface climatic variables on long time scales over large regions, which is, therefore, the main scientific topic of this work. Due to a large amount of reanalyses differing in e.g. assimilated type of data and model used for their calculation, the comparison of representation of circulation modes and their temporal evolution of relationships with surface climatic elements is conducted between reanalyses. Circulation modes in reanalyses assimilating both surface and upper troposphere/satellite data (ERA40, JRA-55, NCEP-1) are mostly similar whereas the 20CRv2c reanalysis, which utilizes surface data only, contains biases. Although...

Report on the Environment of the Czech Republic 2021
Česká informační agentura životního prostředí (CENIA)
The Report on the Environment of the Czech Republic (the “Report”) is drawn up every year on the basis of Act No. 123/1998 Coll., on the right to information on the environment, as amended, Government Resolution No. 446 of 17 August 1994, and Government Resolution No. 934 of 12 November 2014. It is submitted to the Government of the Czech Republic for approval and subsequently to the Chamber of Deputies and the Senate of the Parliament of the Czech Republic for debate. It is a comprehensive document assessing the state and development of the environment in Czechia from all aspects based on the data available for the year under assessment. The Czech Environmental Information Agency has been responsible for drawing up the Report on the Environment of the Czech Republic since the 2005 Report. The Report concept was revised in 2018. As a result, a detailed version of the Report is now prepared every two years, and in the intervening period the most important information on the state and development of the environment is published in concise form. The 2021 Report is one of those concise versions. Starting with the 2020 Report, the content concept and structure of the Report, based on the State Environmental Policy of the Czech Republic 2030 with a view to 2050, has been changed to enable the continuous assessment of its indicators and meet the set goals and priorities. The main areas are based on the State Environmental Policy 2030 (1. Environment and health, 2. Climate-neutral and circular economy, 3. Nature and landscape) and are framed by other topics central to the state and development of the environment (Planetary boundaries, Climate change in Czechia, Financing of environmental protection, Opinions and attitudes of the Czech public). The 2021 Report was discussed and approved by the Government on 14 December 2022 and then submitted to both parliamentary chambers for debate. Due to the reporting and processing methodology used, at the time the Report was being drawn up some data sets for 2021 were not available or the data were only provisional. Information on data sets (the reasons for their unavailability and future updates) for which 2021 data were unavailable at the time of publication is provided in the relevant chapters. The 2021 Report is simultaneously published electronically (https://cenia.cz, https://www.mzp.cz) together with the Statistical Environmental Yearbook of the Czech Republic 2021 and Reports on the Environment in the Regions of the Czech Republic 2021. Detailed data sources are available on the Envirometr portal (https://www.envirometr.cz).

Climate and settlement dynamics based on comparison of dendroclimatic and archaeological data of South Bohemian holocene.
VOBEJDA, Libor
The environment is influenced by the ever changing system of interacting forces. Changes in the climate are amongst many crucial factors that determine life conditions on Earth. All organisms have to cope with the environmental changes and humans are no exception. This thesis is focused on description of climate changes during the Holocene geological epoch. The climate is delineated based on proxy datasets. South Bohemian proxy data, mainly tree ring chronology, are used as primary sources for the reconstruction of past climate. These proxy datasets are complemented by various climatic reconstructions covering the area of central Europe. In order to assess the connection of past human societies to climate, a comparison between climate and settlement proxies is conducted. As an example of the settlement proxies we can list relative population density and location of dwellings. Target populations are agricultural prehistoric and historic societies.
