The main objective of the thesis was a compilation of a bilingual English-Czech glossary of climate change terminology. More specifically, a glossary of terms not covered in the 2009 revised version of the leading bilingual dictionary concerned with the environment, i.e. Anglicko-český a česko-anglický slovník životního prostředí a udržitelného rozvoje. The English terms were extracted from various monolingual climate change glossaries, the main source being the glossary of the Synthesis Report of the Fourth Assessment Report published by the Intergovernmental Panel on Climate Change in 2007. The thesis itself first presents readers with background information concerning the key notions term and terminology. In this rather theoretical part, readers are, apart from other issues, also made familiar with practical aspects of terminology such as terminology standardization and terminology management. As far as the practical output of the thesis is concerned, the translation of the terms in question were searched for using a web search engine. Such candidate terms were then evaluated for their credibility and it was also verified whether they are used in the Czech monolingual specialist sources. The performed research revealed not only a lack of bilingual sources but also a substantial lack of monolingual Czech sources dealing with or using the new climate change terminology. Inconsistency in the use of the terminology was detected too. It is for this reason that the bilingual glossary contains both English entries provided with more than one Czech translation and English entries without a Czech equivalent term. The aim is to provide authors of the Anglicko-český a česko-anglický slovník životního prostředí a udržitelného rozvoje with the glossary so they may consider the inclusion of these terms in it and contribute to the improvement of the climate change terminology status in the Czech Republic.
