As the annual United Nations Climate Change Conference (COP29) concludes in Baku, Azerbaijan, the issue of climate change remains pressing, particularly in light of the recent Global Report on Internal Displacement. This report reveals that at least 6.6 million individuals were displaced globally due to weather-related disasters by the end of 2023. Moreover, many of these individuals face repeated displacements; floods, storms, droughts, and wildfires collectively resulted in a staggering 20.3 million forced movements throughout the year. Additionally, 1.1 million people were displaced by natural disasters not linked to climate change, including earthquakes and volcanic eruptions.
Climate change is projected to exacerbate the number of individuals requiring humanitarian assistance, particularly in nations that are already vulnerable to its impacts. Julie Gassien, the global lead on climate and environment at the Norwegian Refugee Council, highlighted the urgent need for action, stating that climate change contributes to an increase in displaced populations and intensifies hazardous events.
Significant displacement was noted in several countries, with China and the Philippines bearing the brunt of the phenomenon; together, they accounted for millions of displacements due to extreme weather such as Typhoon Doksuri, one of the most impactful storms of the season. In Africa, Somalia witnessed the highest displacement numbers on the continent, where catastrophic flooding forced many from their homes, emphasizing the critical intersection of climate change and humanitarian crises.
The annual increase in weather-related displacement incidents has been notable since the Internal Displacement Monitoring Centre initiated monitoring in 2008. Floods and storms alone constituted the majority of these movements, underscoring the relationship between climate events and population displacement—a trend that has escalated in severity and frequency.
Experts suggest that human-induced climate change plays a significant role in amplifying extreme weather conditions, resulting in mounting concerns over future displacement events. Pushker Kharecha, deputy director at Columbia University’s Earth Institute, warns that the expected worsening of climate extremes could persist unless ambitious climate targets, such as limiting global warming to 1.5 degrees Celsius, are met.
The findings indicate that regions in the Global South, including parts of Africa and Asia, experienced a disproportionately high rate of displacement relative to their populations, raising questions about global equity in addressing climate impacts. This concern highlights the necessity for developed nations, which contribute significantly to greenhouse gas emissions, to enhance their support for vulnerable communities worldwide.
In light of these challenges, there is a growing call for systemic changes within international climate negotiations. Leaders and experts have emphasized that current commitments are insufficient. Moving forward, there is a consensus that legally binding agreements, along with fair measures for carbon pricing, are essential to hold nations accountable while considering the unique burdens faced by lower and middle-income countries.
The intersection of climate change and displacement calls for immediate, concerted effort from the global community to create sustainable solutions for those most affected.
