Climate change threatens human life and health by negatively affecting the basic components of health such as clean air, safe drinking water, nutritious food supply, and safe shelter. Türkiye is a country that is largely exposed to climate change with its cosmopolitan location, which is a bridge between Asia and Europe. Due to climate change, serious effects are seen in all sectors from energy to agriculture, from the economy to health. Climate change is defined as the most important global health threat of the next century, and the problems it brings are seen as the most important pressure factor for the life opportunities of future generations. Food and fresh water availability, rising sea levels, abnormal weather events, migration, and diseases are thought to affect human health. A multidisciplinary approach is required to adapt to climate change’s health effects and reduce its negative health effects. In addition, it is predicted that diseases that are about to disappear will re-emerge and become threats. It is thought that as a result of the contamination of food and water resources with the changing ecosystem, some infections will increase and society will face them. Nurses are both affected by climate change and its effects on public health. Nurses who remain in this situation have a great role in providing effective awareness for raising public awareness. In recent years, oncology clinics have not been affected by fire, earthquakes, and pandemics in our country. In this respect, it can be stated that the health service in Turkish oncology clinics is carried out uninterruptedly and by experts in the field. We learned during the pandemic that the whole world is unprepared for the future effects of climate change. In this direction, nurses should think about solutions for the problems related to climate change in the future.
