  We introduce a framework to analyze the conversation between two competing
groups of Twitter users, one who believe in the anthropogenic causes of climate
change (Believers) and a second who are skeptical (Disbelievers). As a case
study, we use Climate Change related tweets during the United Nation's (UN)
Climate Change Conference - COP24 (2018), Katowice, Poland. We find that both
Disbelievers and Believers talk within their group more than with the other
group; this is more so the case for Disbelievers than for Believers. The
Disbeliever messages focused more on attacking those personalities that believe
in the anthropogenic causes of climate change. On the other hand, Believer
messages focused on calls to combat climate change. We find that in both
Disbelievers and Believers bot-like accounts were equally active and that
unlike Believers, Disbelievers get their news from a concentrated number of
news sources.
