AI is acknowledged as an essential tool in the fight against climate change for developing mitigation and adaptive measures. AI mechanisms remain riddles wrapped in an enigma, but their potential is clear. AI can make sense of vast amounts of data to improve climate modeling, leading to more accurate forecasts for extreme weather or environmental changes. This empowers communities and policymakers to plan effective adaptation strategies, such as timely disseminating warnings about impending natural disasters and judicious resource management. AI applications are fast shaping a new, sustainable global energy landscape, from optimizing renewable sources to shrinking carbon footprints. However, the application of AI in climate action also raises ethical dilemmas like biased data that further widen existing inequalities. To address these challenges, it is crucial that AI systems are built and governed ethically and transparently.
