Temperature highs, climate change salience, and Eco-anxiety: early evidence from the 2022 United Kingdom heatwave

Extreme weather episodes may increase the salience of climate change and worsen people's wellbeing. Empirically studying these effects is however challenging, given limited data availability around difficult-to-predict such events. Addressing this issue, I use Google Trends information to assess how climate change salience and people's wellness were affected by an unprecedented mid-July 2022 heatwave in the United Kingdom, when temperatures exceeded 40C for the first time in the country's history. I document a significant rise in the search-intensity for 'climate change', as well as for 'worry' as a marker of psychological distress at the time of the heatwave. In contrast, I show that similar patterns did not emerge in 2019, when comparably high temperatures were recorded, but when the 40C-threshold was not exceeded. Taken together, my results suggest that the effects of the 2022 heatwave are partially driven by a climate anxiety mechanism, wherein extreme weather episodes constitute negative signals for climate change progression. I conclude by discussing several limitations of my study that future work may tackle.
