The climate crisis is an increasingly profound and complex global challenge, affecting lives around the world. Recent research shows that the earth’s temperature has increased by almost 1.2 degrees Celsius since the 19th century. This increase in global temperatures contributes to extreme weather changes, such as floods, droughts and stronger storms. In a new report, scientists warn that if greenhouse gas emissions are not reduced significantly, we will face an increase in global temperatures of up to 2 degrees Celsius by 2040. This increase could cause the loss of natural habitats and accelerate the extinction of species. The agricultural sector is also threatened by changing rain patterns and rising temperatures, which could affect global food production. Big cities are at the center of the impact of the climate crisis. Rapid urbanization and inadequate infrastructure make many cities vulnerable to flooding and heat waves. For example, Jakarta, which is located in the lowlands, is expected to experience land subsidence of up to 25 cm per year due to excessive groundwater extraction. Mitigation measures are needed to maintain the sustainability of these cities. The climate crisis is also exacerbating social injustice. The countries hardest hit by climate change are usually developing countries that have limited resource capacity to adapt. In addition, vulnerable community groups, including small farmers and indigenous communities, are more easily affected by the impacts of change. Energy sustainability is key to overcoming the climate crisis. Switching from fossil fuels to renewable energy, such as solar and wind power, can help reduce emissions. Countries such as Germany and Sweden have shown that economic decarbonization can be possible with the right policies and investment in sustainable infrastructure. The Paris Agreement is an important milestone in the global commitment to addressing the climate crisis. Although many countries have promised to reduce emissions, the realization is often not in line with these goals. Close monitoring and transparent reporting from participating countries is essential to ensure accountability and progress. Technological innovation also plays an important role in mitigating the climate crisis. Carbon capture and storage (CCS) and the development of electric vehicles are some examples of how technology can be used to reduce emissions. Private companies, in this case, also have a responsibility to adopt environmentally friendly practices in their operations. Public awareness of the importance of action on climate change continues to increase. Collective action from individuals and communities has proven its ability to drive policy change. The global climate movement, spearheaded by young activists, is increasingly highlighting the importance of acting to save the planet. In the face of the deepening climate crisis, collaboration between countries and active participation from all levels of society is the key to creating a better and safer world for future generations. By prioritizing sustainability and justice, there is hope to repair the damage that has been done and prepare for a brighter future.
