Purpose
The purpose of this investigation is to analyze information on the web and its preservation as a digital heritage, having as object of study information about events related to climate changes and the environment in Portugal and Brazil, thus contributing to an applied case of preservation of web in the Ibero-American context.
Design/methodology/approach
It is a theoretical and applied investigation and the methodology uses mixed methods, collecting and analyzing quantitative and qualitative data, from three data sources: the Internet Archive and public collections of Archive-it, the Portuguese web archive and a complementation from collections formed by the research group on web archiving and digital preservation in Brazil.
Findings
The web archiving initiatives started in 1996, however, over the years, the collections have been specializing, from nationally relevant themes, to thematic niches. The theme “climate changes” has had an impact on scientific and mainstream discussions in the 2000s, and in the years 2010 the theme becomes the focus of digital preservation of web content, as demonstrated in this study. To not preserve data can lead to a rapid loss of this information owing to the ephemerality of the web.
Originality/value
The originality of this paper is to show the relevance of preserving web content on climate changes, to demonstrate information on climate changes on the web that is currently preserved and what information would need to be preserved.
