<abstract>The escalating impact of climate change on our environment and lives has spurred a global surge in climate change activism. However, the misuse of social media platforms like Twitter has opened the door to the spread of hatred against activism, targeting individuals, organizations, or entire communities. Also, the identification of the stance in a tweet holds paramount significance, especially in the context of understanding the success of activism. So, to address the challenge of detecting such hate tweets, identifying their targets, and classifying stances from tweets, this shared task introduced three sub-tasks, each aiming to address exactly one mentioned issue. We participated in all three sub-tasks and in this paper, we showed a comparative analysis between the different machine learning (ML), deep learning (DL), hybrid, and transformer models. Our approach involved proper hyper-parameter tuning of models and effectively handling class imbalance datasets through data oversampling. Notably, our fine-tuned m-BERT achieved a macro-average $f1$ score of 0.91 in sub-task A (Hate Speech Detection) and 0.74 in sub-task B (Target Identification). On the other hand, Climate-BERT achieved a $f1$ score of 0.67 in sub-task C. These scores positioned us at the forefront, securing 1st, 6th, and 15th ranks in the respective sub-tasks.
