Climate change contributes significantly to the increase in the frequency and intensity of natural disasters throughout the world. Rising global temperatures as a result of greenhouse gas emissions have had devastating impacts on ecosystems and communities. One of the biggest impacts is an increase in the frequency of extreme weather disasters, such as storms, floods and droughts. Rising sea surface temperatures cause storm cycles to become more intense. Warmer water temperatures increase water vapor in the atmosphere, creating more powerful storm systems. For example, Hurricane Harvey in 2017 set rainfall records in Texas, caused by a global warming phenomenon that has strengthened tropical storm power. These changes create huge challenges for societies that are not prepared to face this scenario. Floods triggered by heavy rains are also becoming more common. Unexpected rainfall causes rivers to overflow, triggering damage to infrastructure, loss of property, and posing a threat to human life. In Southeast Asia, countries such as Bangladesh and India experience increasingly severe annual floods, affecting millions of people and causing humanitarian crises. Financial losses due to these flood disasters reach billions of dollars, exacerbating economic instability. Drought is another phenomenon that is becoming more frequent as a result of climate change. Rising temperatures cause high evaporation and reduce soil moisture, which impacts agricultural yields. Once fertile regions, such as parts of Africa and California, are now threatened with loss of food security. This situation is driving mass migration, fueling social conflict, and adding to the burden on an already vulnerable country. The effects of climate change also create greater threats to the global health system. Rising temperatures contribute to the spread of vector-borne diseases, such as malaria and dengue. Previously unaffected areas have now become vulnerable to the disease, triggering a wider health crisis. Underprivileged communities are often the main victims, due to lack of access to adequate health services. In addition, climate change changes weather patterns that impact ecosystems. Coral reefs, which are home to a variety of marine species, are being destroyed by rising temperatures and ocean acidification. The mass death of coral reefs affects fisheries ecosystems and, in turn, threatens the livelihoods of coastal communities. Lastly, the impact of climate change on global natural disasters cannot be ignored. The sum of these risks demands urgent global policy attention. Countries need to work together to reduce carbon emissions, increase societal resilience, and build infrastructure that can withstand natural disasters. Thus, mitigation and adaptation measures must become an integral part of sustainable development strategies at all levels.
