The recent COP28 and COP29 (as other COPs) have demonstrated clearly how political and corporate interests play a central role in the framing of the final “compromise” agreement. These dynamics raise critical questions about the relationship between climate policy and power structures, where dominant states, lobbyists, research institutions, and energy corporations often influence the terms of climate dialogue, sometimes overlooking the pressing issue of human security amidst the climate crisis. Notably, the backlash against globalization has emerged as a significant force in these discussions. Public dissent has been driven by the perception that globalization exacerbates economic inequality and undermines local economies, thereby threatening human agency and community resilience. This chapter explores the climate-security nexus and its connections to the volume’s theme on reglobalization. It critically analyzes the political power dynamics that shape global climate change narratives and their implications for human security, while addressing the backlash against globalization. It also examines major power players (states, corporations, research institutions) and assesses how their narratives align (or don’t) with meaningfully addressing critical human security challenges caused by the destructive impacts of climate change at the global scale. Exploring the backlash against globalization is crucial for advancing a robust discourse on climate change and human security. Reglobalization reshapes economic and political landscapes toward inclusivity and equity. The argument highlights the need to integrate frameworks that reconcile individual and community resilience with broader global imperatives. Finally, it proposes an alternative approach to climate security centered on human agency, emphasizing empowerment, equity, inclusion, and empathy. This multifaceted exploration of the climate-security nexus and economic inequality, political power disparities, resource exploitation, and indigenous marginalization connects with reglobalization and the growing global movement for change, climate justice, and collaborative action holding hope for saving both the planet and humanity.
