Abstract
Humans are causing climate change, and global action needs to be taken to limit any negative effects on humankind and the Earth. This paper will show that, although climate activism on Facebook and Twitter by individuals has increased in popularity and effectiveness in the last two years, the ongoing dissemination of disinformation to these same social networking sites (“SNSs”) causes confusion, which results in public interest in action to curb climate change remaining limited. SNSs produce a networked public, with influencers such as Greta Thunberg and organizations such as Fridays for Future and the Climate Council able to use platform affordances to effectively advocate for climate action, encouraging likeminded individuals to form networks on Facebook and Twitter which assist with online and offline actions to pressure policymakers to act on climate change. Simultaneously, the widespread release of disinformation on Facebook and Twitter means these same affordances lead users to innocently share disinformation and distribute misinformation which is reinforced and amplified in users’ filter bubbles and echo chambers, resulting in ongoing public confusion about the reality of climate change. Such misinformation limits the number of participants acting to achieve social change, restricting real social change and effective collective action.
