Climate change has become an urgent global issue, and its impact on flooding phenomena has put many regions in the world at risk. This phenomenon is influenced by factors such as increasing temperatures, extreme rainfall and melting ice in the polar regions. As a result, various areas experience a higher potential for flooding and more frequent flooding. One of the most significant impacts of climate change is increasing global temperatures, which leads to an increase in the amount of water vapor in the atmosphere. According to research, every degree Celsius increase in temperature can increase the atmosphere’s capacity to hold water by up to 7%. This has direct implications for increasing the intensity and frequency of heavy rain, which results in flooding. Metropolitan cities, which are densely populated and have fragile infrastructure, are the main targets. Floods are also influenced by melting polar ice and glaciers. As temperatures rise, the ice sheets in Greenland and Antarctica begin to melt rapidly, causing sea levels to rise. This not only threatens coastal communities but also increases the risk of flooding in previously safe areas. Coastal Asia, including countries such as Bangladesh and Vietnam, is particularly vulnerable to these impacts. In addition, unsustainable land use also worsens the risk of flooding. Rapid urbanization without adequate drainage planning means that rainwater cannot be absorbed properly. As a result, waterlogging and flooding have become common problems in big cities. Deforestation and land conversion to agricultural areas also reduce the soil’s ability to absorb water, worsening the situation. Floods caused by climate change not only cause physical damage to infrastructure, but also affect public health. Air-borne diseases and the psychological impact of losing housing and livelihoods can worsen quality of life. Affected families are often forced to flee, increasing the number of refugees and straining other regions’ resources. Governments and international organizations need to be proactive about the increasing risk of flooding due to climate change. Mitigation efforts such as building green infrastructure, improving drainage systems, and planting trees must be a priority. In addition, public education about climate change and ways to mitigate disasters is very important. To address this crisis at a global level, effective international collaboration is essential. Countries must share technology and information and invest in research to better understand the impact of climate change on weather patterns and flooding. With the right actions, we can mitigate the impact of global flooding as a result of increasingly real climate change.
