This dataset contains the Twitter IDs of all ~20M tweets containing the phrase "climate change" 2018-2021. Additionally, it contains the topical annotations and 2D semantic representation of our thematic analysis based on ~980 topic clusters that are grouped by hand into seven themes (COVID-19, Politics, Contrarian, Movements, Solutions, Impacts, Causes) as well as "non-relevant/spam", "others", and highlighting of potentially interesting topics. Code and additional notes are available on GitHub: https://github.com/TimRepke/twitter-climate The topics, including statistics and the annotator labels for broader themes (aka "super topics") are contained in the spreadsheet.
