Artificial Intelligence (AI) has gained global popularity as a technological innovation in many spheres that recreates a process or situation in an automated mode of intelligence like humans. For Climate Change (CC), AI can support applications in adaptation and mitigation covering energy, agriculture, economy, etc. Using AI in constantly evolving environmental scenario enables access to climate insights informing adaptation and mitigation efforts. AI can be leveraged to enumerate physically uncountable people and other assets endangered by CC, causing natural disasters as climate crisis exacerbates. It can also be used for wildfire estimated at annual global cost of about $50 billion for prediction, prevention and optimal resource allocation for sustainable forest management. In Nigeria, though CC policies are a vital component for implementation of climate actions, including the implementation of SDG13—regulatory agencies are reluctant to adopt AI applications. Using the doctrinal methodology, this paper finds that, although Nigeria has adopted diverse approaches to climate change governance, many are inadequate due to the inability to embrace AI technology and other innovations. The challenge is that legislative arrangements in Nigeria do not regulate robotics. Thus, the paper argues for the application of AI to enhance adaptation and mitigation policies. It concludes that legal and institutional arrangements in Nigeria should integrate AI for sustainable development efforts to anticipate future CC developments and provide adequate solutions.
