* The contribution of the vector database to improving QA performance is unclear. More analysis and ablation studies are needed to determine its impact and value for the climate change QA task.
* Details around the filtering process used to create the Arabic climate change QA dataset are lacking. More information on the translation and filtering methodology is needed to assess the dataset quality.
* The work is focused on a narrow task (climate change QA) in a specific language (Arabic), so its broader impact may be limited.
* The limitations section lacks specific references to errors and issues found through error analysis of the current model. Performing an analysis of the model's errors and limitations would make this section more insightful.
