We investigate the determinants of people's attention to climate change in Italy. We propose a Twitter-based indicator consistent with traditional survey data but potentially available at a higher frequency and spatial granularity. We show that attention to climate change is heterogeneous across the country and correlated with socioeconomic characteristics and social capital. Mass media and social movements have a relevant impact on people's attention about climate change while the effect of private experience – proxied by the occurrence of extreme weather events – is more limited.
