• Climate change can lead to more frequent and intense natural disasters, such as hurricanes, flooding, droughts, and wildfires. These disasters can cause displacement and migration, which can lead to competition for resources and potential conflict.
• The impact of climate change on food and water insecurity can lead to increased tensions between states and within countries. These tensions can lead to violence and destabilization, particularly in regions with pre-existing political, social and economic vulnerabilities.
• Climate change can also impact global economy, leading to economic hardship and instability and thus impacting security of various nations.
• The melting of Arctic ice due to climate change has led to increased competition over resources, including oil and gas reserves, fishing grounds and shipping passage, which can cause tension between states especially considering the claims of territory of different nations.

All these factors can lead to regional and global instability, weaken state institutions, and contribute to broader geopolitical tensions. It is therefore important for the international community to take action to address climate change to prevent future negative impacts on international security.
