Several current youth-led activism movements center on the ongoing climate crisis. Youth activists such as Greta Thunberg, the founder of “Skolstrejk för klimatet” (School strike for the Climate) are voicing their concerns and directing public attention to rising temperatures and the increasing scarcity of clean water and food among other issues. Collectively, these youth leaders are pressuring politicians and fellow citizens to acknowledge the increasingly dismal state of the planet they are bequeathing future generations. These digital natives connect, disseminate information, and organize online to mobilize significant in real-life (IRL) gatherings to better garner the attention of mainstream media and society. In this chapter, we discuss the digital tools utilized by current youth-led climate movements that operate at global (Fridays for Future Movement) and national levels (US-based Sunrise Movement).
