Global climate change is an important issue that is increasingly urgent to face. Danger signs that have emerged in the last few decades have shown a significant impact on various aspects of life. In this context, it is important to understand further the various phenomena that are indicators of climate change. One of the clearest signs is an increase in global temperatures. Data from NASA shows that Earth’s temperature has increased by about 1.2 degrees Celsius since the end of the 19th century. This temperature increase is caused by greenhouse gas emissions resulting from human activities, such as burning fossil fuels and deforestation. Rising temperatures result in melting of polar ice, which in turn causes sea levels to rise. Changes in weather patterns can also be a danger signal. Extreme weather phenomena, such as floods, droughts and storms are increasingly occurring. According to the World Meteorological Organization (WMO), meteorological disasters have increased significantly, with economic impacts reaching billions of dollars. Previously stable areas are now vulnerable to extreme changes, threatening food security and water resources. One of the long-term impacts of climate change is increasing ocean acidity. The absorption of carbon dioxide by the ocean causes a drop in pH that is dangerous for marine ecosystems. Korali, which provide habitat for various fish species, are at high risk due to climate change. Coral reef destruction threatens biodiversity and fishermen’s livelihoods. In addition, air pollution due to vehicle and industrial emissions contributes to human health. Respiratory diseases, such as asthma and bronchitis, are increasing along with worsening air quality. WHO data reports that around 4.2 million deaths per year are related to air pollution. This condition shows the urgency in adopting clean and environmentally friendly energy. Climate change also has social impacts, especially for vulnerable communities. Developing countries, which have limited adaptive capacity, are the worst victims. Climate migration is becoming a reality, with millions of people forced to flee their homes due to weather-related disasters. Resource conflicts may also increase as water and food supplies decrease. International initiatives, such as the Paris Agreement, aim to reduce emissions and mitigate the impacts of climate change. However, the rise of fossil-based industries in several countries shows major challenges in achieving this target. Public awareness of this issue is also very important. Education and information can be key tools in driving change in individual behavior and public policy. Mitigation efforts such as tree planting and renewable energy development need to be accelerated. Nature-based solutions can play a role in carbon sequestration while protecting biodiversity. By adopting sustainable practices, not only is the environment protected, but also people’s health and welfare can be guaranteed. In dealing with climate change, collaboration between government, the private sector and civil society is urgently needed. Every individual can contribute through reducing their carbon footprint, more conscious consumption habits, and supporting pro-environmental policies. By understanding and responding to these danger signs, we can strengthen resilience to the increasingly visible impacts of global climate change.
