Global climate change is an urgent issue that affects all aspects of life on earth. With the increase in global average temperature, various impacts are starting to be seen in various parts of the world. One significant impact is an increase in the frequency and intensity of natural disasters, such as floods, droughts and tropical storms. Data shows that from 1970 to 2018, economic losses due to natural disasters doubled, triggered by extreme weather changes. The ecosystem is also experiencing serious impacts. Coral reefs, one of the most vulnerable marine ecosystems, are experiencing mass bleaching due to rising sea temperatures. With more than 500 million people depending on coral reefs for their livelihoods, this damage has the potential to increase poverty in coastal areas. Meanwhile, biodiversity is threatened when natural habitats are lost due to climate change and human activities. In the agricultural sector, climate change results in a decrease in crop yields through changes in rainfall patterns and an increase in extreme temperatures. A study shows that developing countries, which depend on agriculture, experience a decline in output of 10% per decade. This adds to global food security challenges, especially in countries in Africa and South Asia. The health sector is also not immune from the effects of climate change. Rising temperatures and changing weather patterns can increase the spread of infectious diseases, such as malaria and dengue. Floods also have the potential to damage health infrastructure and cause a nutrition crisis. In this case, children are the most vulnerable group, with an increased risk of malnutrition. Climate change also affects water resources. Longer dry seasons result in reduced availability of clean water, which can worsen health conditions and impact economic activity. In some areas, reduced water quality due to pollution worsens the situation, creating additional challenges for governments to provide access to adequate water. Addressing the impacts of climate change requires global collaboration. Mitigation and adaptation policies are the key to reducing the impact. Additionally, environmentally friendly technologies, such as renewable energy, are important for reducing greenhouse gas emissions. A community-based approach is also needed to increase community resilience to climate change. Investments in education and environmental awareness empower communities to act responsively to these issues. Through effective education programs, people can understand the importance of environmental conservation and ways to adapt to changes that occur. Overall, the impacts of global climate change are vast and complex. With multiple sectors of life affected, it is important for individuals, governments and global organizations to work together to find sustainable solutions. Continuous research and critical monitoring of developing climate trends will also be an integral part of the strategy to overcome this challenge in the future. With collective awareness and action, we can respond to these issues and create a more sustainable world.
