For large parts of the general public, media are the central source of information about climate change, and today people are increasingly turning to the online services offered by classic and newer media providers in order to stay informed. Therefore, analyses of online reporting are important for the understanding of how climate change is constructed in public debates.
To contribute to this goal an Online Media Monitor for climate change will be developed. This will result in a website offering CliSAP-members an access to data of an automated daily updated monitoring of the climate debate in online media. The project will thus expand the available social-scientific data on climate change.This project was part of the CliSAP idea contest 2015.
The OMM consists of 2 parts:
- worldwide online climate reporting analysis from news sites
- Twitter analysis (this data set)
Which data from Twitter are considered?
The OMM searches Tweets that are related to climate change. The following tweets are considered:
- At least one of these search strings has to be present: #climatechange OR "climate change" OR "global warming" OR Klimawandel
- At least 5 retweets
Until Jan 18, 2021, there had to be additionally at least one link in the tweet. It should be noted that the Twitter API truncates the text of the tweet after 140 characters and in this case a link to Twitter is placed in the text directing to the complete tweet. We evaluate this link as the first one.
OMM downloads yesterdays tweets at 3 am (UTC) to provide the possibility of retweets.
In addition to the tweet count per day (from March 2017 on), two more products are generated by these data sets. The domains of the first links of every tweet are extracted and a ranking over these domains is generated, aggregated over different periods. Additionally, yesterday’s most retweeted tweet is shown.
|Domain ranking||The Domains are extracted from the first link in the tweet. The count is aggregated over several time periods.|
|Yesterday's most retweeted tweet||Yesterday's climate change tweet showing most rewteets|
|Count per day||Time Series of climate change tweets per day|
