The document discusses climate change as a critical global issue stemming from human activities, particularly emphasizing the urgent need for international cooperation to address its adverse effects. Key international agreements, such as the Kyoto Protocol and Montreal Protocol, highlight the importance of enforceability and accountability in climate action, while the Paris Agreement aims to limit global temperature rise. Challenges to cooperation include varying national priorities, free-riding concerns, and the need for financing, yet technological innovations and grassroots movements signify hope for meaningful change.
