<p>Inhabitants in urban slums are among the most susceptible to the brunt of climate change. Urban slums are characterized by congestion, poor housing designs, lack of infrastructure and limited access to essential services which make inhabitants ill-equipped to cope with climate change related events. The lack of knowledge about climate change by inhabitants in urban slums exacerbates their susceptibility, making them more vulnerable to climate-related events. This study extends climate research into slum residents, focusing on how digital tools enhance climate literacy among slum dwellers in Ghana. The exploratory design within the remit of qualitative methodology was utilized. The findings show that slum inhabitants use mobile phones and social media, particularly WhatsApp, to create climate awareness. Furthermore, slum dwellers mitigate climate action through community mobilization, resources and implementation of climate actions. This study provides contextual reality and knowledge that climate literacy in slums could be enhanced through mobile phones and climate events mitigated through community mobilizations and collective actions. The contributions of this study lie in the successful provision of empirical understanding about slums’ climate literacy using digital tools. In addition, Digital Ecological Resilience Theory (DERT), which is rarely utilized in studies on urban slums in developing countries, has successfully provided the context and helped answer the research questions. Such an approach indeed marks a significant theoretical contribution to our study. This study remains one of the few that examine slum climate awareness, focusing on digital tools through the DERT lens.</p>
