Climate change is a global phenomenon that includes changes in temperature, rainfall patterns, and extreme weather that is increasingly occurring. The main cause of climate change is greenhouse gas (GHG) emissions resulting from human activities, such as burning fossil fuels, deforestation and industrialization. The impact is widespread, with various consequences that threaten health, the economy and environmental sustainability. One of the most significant impacts of climate change is increasing global average temperatures. According to the IPCC report, global temperatures have increased by about 1.2 degrees Celsius since the pre-industrial era. This increase in temperature contributes to melting polar ice and rising sea levels. Coastal areas are particularly vulnerable, with millions of people at risk of displacement due to flooding. Changes in rainfall patterns are also an important concern. Some areas experience excess rain, while others experience severe drought. This phenomenon affects clean water supplies and food accessibility, which in turn threatens global food security. In the agricultural context, climate change disrupts the growing season and reduces crop yields, which has a direct impact on the economy of small farmers. Extreme weather such as hurricanes, heat waves and forest fires are becoming increasingly common and intense. These events harm not only society, but also natural habitats, accelerating species extinction and reducing biodiversity. The consequences of biodiversity loss impact ecosystem balance, which is important for environmental stability. Developing countries are often most affected by climate change. They have limited resources to address climate impacts, leaving vulnerable populations more vulnerable to uncertainty. The existence of inequality in the contribution of GHG emissions, where developed countries contribute more, adds to the complexity of this problem. Efforts to improve these conditions are often hampered by political and economic challenges. Climate education and public awareness are the keys to dealing with climate change. Communities need to be involved in proactive actions to reduce their carbon footprint through reducing energy consumption, choosing renewable energy sources and better waste management. Active involvement from the private sector is also very important in supporting environmentally friendly technological innovation. The shift towards a green economy offers an opportunity to meet the challenges of climate change. Investments in clean technology, renewable infrastructure, and sustainable practices can create new jobs and support sustainable economic growth. International cooperation is also crucial in efforts to mitigate climate change, with various agreements such as the Paris Agreement requiring countries to commit to helping each other in reducing emissions. In facing these challenges, a multi-dimensional approach is needed. Every individual, community and country has an important role to play in creating effective solutions to combat climate change. Through global collaboration, innovation and concrete action, the world can work towards a safer and more sustainable future in response to this serious threat.
