Research on long-term media coverage of environmental issues has focused predominantly on English-speaking industrialized countries and on single isolated topics. This article presents a comparative analysis of the Finnish newspaper coverage of climate change and eutrophication from 1990-2014. The coverage of eutrophication showed an annual cycle with summertime peaks strongly influenced by local conditions and domestic news sources. The coverage of climate change had three distinctive peaks, influenced by several factors including international climate policy negotiations, domestic energy debates, and mild and snowless winter weather. The prospects for building public awareness of environmental issues through media representations are discussed.
