Abstract
This study conducts a comparative sentiment analysis of climate change discourse on X (formerly Twitter) between India and Europe from 2015 to 2022. Using over eight million English-language posts, it examines regional differences in emotional tone toward climate issues. Sentiment scores were derived through the VADER lexicon and statistically analyzed using t-tests and MannWhitney U tests. Results indicate that both regions discourse centers near neutral sentiment but diverges significantly in average tone: Europes tweets are slightly more positive (mean +0.02) while Indias are marginally negative (mean 0.05). The findings align with prior surveys showing higher climate awareness and policy confidence in Europe and uneven awareness and heightened anxiety in India. Education and exposure to extreme weather events correlate with sentiment variation, with more educated or policy-engaged regions expressing optimism and impacted regions expressing urgency or distress. Content analysis reveals that European tweets emphasize renewable energy and solutions, whereas Indian tweets often reflect heatwaves, pollution, and developmental trade-offs. The study highlights how sociopolitical and informational contexts shape digital climate discourse and underscores the importance of region-specific climate communication strategies.KeywordsClimate change communication, Sentiment analysis, Social media, India, Europe, Twitter, Public opinion, Environmental discourse, Climate awareness
