The purpose of Master thesis „Greta Thunberg – A New Face of the Climate Change Movement: An Analysis of Reporting on Online Editions of The Guardian and Večernji list in 2019“, in the context of current reporting about climate changes, was to represent how online editions of The Guardian and Večernji list reported on young Swedish activist Greta Thunberg in the period from the 1 January 2019 to the 31 December 2019. The method used for the research was content analysis, conducted on the sample of 197 articles in total, including the graphic equipment of the articles. Articles were searched by the key words “Greta Thunberg” on online editions of The Guardian and Večernji list. The research wanted to determine the tone of the reporting, mention of the climate changes in the articles and in what way, what was the headline type, was the Asperger syndrome mentioned, what was the type of articles graphic equipment, also what was the value orientation of the headlines, the relation between the text and the headline and whether child's right to dignity has been violated. All six hypotheses have been confirmed. The results show that both online editions reported mostly neutral about Greta Thunberg in their articles. Still, the reporting in the columns of Večernji list was more negative/critical, than in the columns in The Guardian, where reporting was more positive/laudable. The articles were also focused on climate changes in both editions, however articles in Večernji list mentioned Asperger syndrome more often then articles in The Guardian. Večernji list's headlines were mainly sensationalist, while The Guardian's headlines were mainly informative. In the photos which Večernji list used Greta was more often shown angry, while in the photos which The Guardian's used Greta was more often shown happy. These results show that there is a difference between The Guardian's and Večernji list's reporting. Večernji list reported in a more sensationalist manner without a designated source, also violating child's right to dignity.
