Climate change is an increasingly urgent global problem, causing significant impacts on the environment, economy and social life. Amid increasing scientific consensus on global temperature change, the main causes can be traced to greenhouse gas emissions from human activities, such as the burning of fossil fuels, deforestation, and intensive agriculture. One of the most obvious impacts of climate change is an increase in global temperatures. Earth’s average temperature has risen about 1.2 degrees Celsius since the end of the 19th century. This causes melting of polar ice and sea level rise. Coastal countries, such as Indonesia, are very vulnerable to climate shifts that threaten the existence of small islands and disrupt the lives of people who depend on marine resources. Moreover, climate change is impacting weather patterns, causing extreme phenomena such as prolonged droughts and more intense storms. Drought threatens food security, affects agricultural production, and increases the risk of famine. Regions that were already food insecure areas are increasingly deteriorating, creating an emergency that requires a rapid response from the government and humanitarian agencies. Apart from physical impacts, climate change also affects people’s health. Rising temperatures create an environment conducive to the spread of infectious diseases, such as malaria and dengue fever. Deteriorating air quality due to pollution contributes to an increase in respiratory problems among vulnerable populations. Despite these challenges, there is hope through global innovation and collaboration. Mitigation actions, including the development of renewable energy such as solar and wind power, play an important role in reducing carbon emissions. Countries, through international agreements such as the Kyoto Protocol and the Paris Agreement, are committed to reducing greenhouse gas emissions and increasing sustainability. Education is also the key to overcoming this problem. An informed society can take sustainable steps in everyday life, from reducing plastic use to supporting local products. In this case, the role of individuals is very significant in building a greener and more sustainable future. In the industrial sector, the transition to a circular economy, which emphasizes the reuse and recycling of resources, is expected to reduce the carbon footprint and create a more efficient system. Companies that invest in green technology not only contribute to environmental conservation, but also attract consumers who are increasingly concerned about sustainability. By acting now, the world can take concrete steps to address climate change. The global community must unite, prioritize innovation, and strengthen its commitment to safeguarding the planet for future generations. The rapidly changing climate requires not only understanding, but also concrete action from every individual and organization. This is a call to safeguard biodiversity, create social resilience, and ensure sustainable economic prosperity throughout the world.
