Climate Change from Large Language Models

Climate change presents significant challenges to the global community, and it is imperative to raise widespread awareness of the climate crisis and educate users about low-carbon living. Artificial intelligence, particularly large language models (LLMs), have emerged as powerful tools in mitigating the climate crisis, leveraging their extensive knowledge, broad user base, and natural language interaction capabilities. However, despite the growing body of research on climate change, there is a lack of comprehensive assessments of climate crisis knowledge within LLMs. This paper aims to resolve this gap by proposing an automatic evaluation framework. We employ a hybrid approach to data acquisition that combines data synthesis and manual collection to compile a diverse set of questions related to the climate crisis. These questions cover various aspects of climate change, including its causes, impacts, mitigation strategies, and adaptation measures. We then evaluate the model knowledge through prompt engineering based on the collected questions and generated answers. We propose a set of comprehensive metrics to evaluate the climate crisis knowledge, incorporating indicators from 10 different perspectives. Experimental results show that our method is effective in evaluating the knowledge of LLMs regarding the climate crisis. We evaluate several state-of-the-art LLMs and find that their knowledge falls short in terms of timeliness.
