Cyberactivism, SIMCA model and collective action against climate change

Climate change is one of the main challenges facing humanity. According to the Intergovernmental Group of Experts on Climate Change, a rise in sea level, as a result of greenhouse gases, of between 24 and 30 centimeters and 40 to 63 centimeters is expected for 2065 and 2100, respectively (IPCC, 2013 ). In 2018, a study determined that limiting the temperature rise to 1.5 degrees compared to the projected 2 degrees would require radical changes in multiple spheres of human endeavor (IPCC, 2018).

Due to the complexity and magnitude of climate change, the initiatives to face it are related to collective actions (Brenchin, 2016), being the Social Identity Model of Collective Action (SIMCA) an alternative that allows systematically explaining these initiatives (Van Zomeren , Postmes and Spears, 2008; Van Zomeren, Postmes, Spears and Bettache., 2011). On the other hand, various authors suggest that an element that connects and enables collective actions is cyberactivism; numerous movements, which have resulted in massive demonstrations in the real world, have organized on social networks such as Facebook and Twitter (Tufecki and Wilson, 2012; Alberici and Milesi, 2013; Cabalin, 2014; Díaz, 2015; La República, 2016) .

Consequently, given that cyberactivism is connected with collective actions, and climate change being a topic of great relevance, this study will seek to explain the relationship between cyberactivism and collective actions against climate change using the variables of the SIMCA model.
