Societal attention has a major influence on political decisions, for example on climate protection and adaptation measures. However, attention is not constantly high, but fluctuates between high and low phases, in so-called attention cycles. In addition, growing accustomed to climate impacts, such as very hot and dry summers, can lead to reduced attention and thus potentially to insufficient climate protection measures.

I am investigating attention cycles on climate change and especially on weather extremes by means of a systematic and quantitative analysis of media coverage. My analysis focuses on the medium "newspaper" and I prepare, classify and statistically analyse newspaper archive data. In doing so, I approximate public attention by the number of topic-specific press articles, a well-established procedure in the literature.
