Testing the credibility of historical newspaper reporting of extreme climate and weather events

摘要

In recent years, newspaper research has been streamlined by digitisation and online hosting by PapersPast. This paper tests the reliability and credibility of reporting of extreme weather and climatic events through PapersPast to determine if newspaper research of past climate can be further streamlined. Searches were conducted through four early-20th-century Auckland newspapers, where counts of articles returned by key-word searches for particular periods were compared against periods of known extremes. We find that blind searches have only limited potential in identifying extreme weather and climatic events and that they are no substitute for thorough analyses of documentary sources.
