Climate change has become an increasingly pressing global issue, and the threats it poses are increasingly worrying people and scientists around the world. Recent data shows that global temperatures continue to rise due to greenhouse gas emissions, most of which result from human activities. According to a report published by the Intergovernmental Panel on Climate Change (IPCC), Earth’s surface temperature has increased by almost one degree Celsius since the pre-industrial era, and without immediate action, temperatures could rise by more than three degrees Celsius by the end of the century. One of the biggest impacts of climate change is an increase in the frequency and intensity of natural disasters. Floods hit vulnerable areas, while forest fires destroyed thousands of hectares of land in various parts of the world. In Indonesia, for example, a longer dry season and erratic rainfall threaten food and ecosystem security. It was recorded that many farmers lost their crops due to extreme weather, which had an impact on the local economy. Apart from that, climate change also triggers the phenomenon of melting of polar ice which causes sea levels to rise. This poses a serious threat to coastal cities, such as Jakarta and Bangkok, which are at risk of sinking. According to a study published by National Geographic, Jakarta could sink up to 95% by 2050 if there are no significant mitigation measures. These changes force the government to consider adaptation strategies, including building flood-resistant infrastructure. The health sector is also affected by the negative impacts of climate change. The spread of infectious diseases increases with changes in weather patterns. For example, malaria and dengue fever are becoming more common in previously unaffected areas. The Centers for Disease Control and Prevention (CDC) warns that vulnerable populations, including children and the elderly, are at increased risk. Not only the health sector, the tourism industry is also threatened by climate change. Destinations known for their natural beauty, such as the Maldives and the Galapagos, have experienced a decline in tourist numbers due to severe environmental damage. Studies show that tourists are increasingly aware of the importance of sustainability, and they tend to choose destinations that demonstrate a commitment to environmental protection. To deal with this threat, various countries have attempted to implement international agreements, such as the Paris Agreement, which aims to limit global temperature rise to below two degrees Celsius. However, many countries still face major challenges in reducing greenhouse gas emissions and switching to renewable energy. Investments in renewable energy such as solar and wind power are becoming increasingly important to achieve these goals. Education and public awareness also play a crucial role in confronting climate change. Awareness campaigns on the need for individual and collective action are essential to drive change. The community is expected to contribute by reducing the use of plastic, saving energy, and supporting local, environmentally friendly products. While there are many challenges to be faced in the fight against climate change, technological innovation offers hope. The development of solutions such as electric vehicles, carbon storage techniques, and sustainable agriculture can provide a way to address the adverse impacts of global warming. All elements of society, from individuals to governments and the private sector, need to work together to create a more sustainable and safe world.
