Climate change has become an urgent global issue, affecting ecosystems, weather and human quality of life. One of the most significant impacts of climate change is the increased risk of flooding, which threatens not only infrastructure but also human life, ecosystems and public health. Places that were previously stable are now facing higher risks from rising temperatures and extreme rainfall. Rising global temperatures cause melting of polar ice and glaciers, which directly contributes to rising sea levels. Data from the Intergovernmental Panel on Climate Change (IPCC) shows that sea levels are increasing by around 3.3 millimeters per year, potentially submerging coastal areas and increasing the risk of flooding. Big cities such as Jakarta, Miami and Bangkok are already starting to feel this impact, and are predicted to face more serious challenges in the coming years. Meanwhile, changes in rainfall patterns also play a role in increasing the frequency of flooding. In many regions, climate change is resulting in more intense storms and unpredictable rainfall. In some countries, long dry seasons followed by heavy rains can cause flash floods that cause significant damage. Tropical and subtropical regions are most vulnerable, with countries such as Bangladesh often in the spotlight due to frequent deep flooding. The consequences of flooding are extensive, ranging from damage to infrastructure such as roads, bridges and residences to the psychological impact on survivors. In addition, floods cause health problems, worsen sanitation conditions, and increase the risk of disease spread. Submerged areas often harbor diseases such as cholera and leptospirosis, straining already weak health systems. Mitigation and adaptation efforts are very important to reduce the impact of flooding due to climate change. Green infrastructure, such as rainwater management and tree planting, can help reduce water runoff and increase soil absorption. In addition, sustainable development and spatial planning must be a priority to protect vulnerable areas. At the global level, collaboration between countries, organizations and civil society is also needed to create effective policies. Commitments to reduce greenhouse gas emissions and strengthen communities’ resilience to climate change will help reduce flood risks. Investment in research and new technology is also important to better predict and respond to flood disasters. Public education about climate change and its impacts, including the risk of flooding, can increase awareness and prepare communities to face disasters. Through training and awareness programs, individuals can learn how to deal with emergency situations and reduce the negative impacts of flooding. Overall, climate change and increasing flood risk are complex challenges that require diverse and collaborative responses. Resilience to the impacts of climate change can be achieved through concrete action at local and global levels, bringing hope for a safer and more sustainable future.
