Global climate change is having a significant impact on biodiversity around the world. This phenomenon occurs due to an increase in the Earth’s average temperature as a result of greenhouse gas emissions. One of the most striking impacts is the loss of natural habitats, which serve as homes for various species. Forests, coral reefs and aquatic ecosystems become vulnerable, causing species that depend on these habitats to become endangered. Increasing temperatures trigger the migration of species to areas with more suitable climates. This causes changes in species distribution patterns, disruption of local ecosystems, and increased competition among species for resources. Certain species, especially in tropical areas where vulnerability is high, are experiencing extraordinary pressure, with an increased risk of extinction. Climate change also affects weather patterns, which impacts the availability of food resources for animals. For example, longer dry seasons and unpredictable rains disrupt animals’ reproductive cycles. Many species experience population declines due to difficulties in finding food, which ultimately impacts overall biodiversity. The phenomenon of global warming also contributes to seasonal shifts. This causes a mismatch between reproductive timing and food availability, which can worsen the survival of larvae and young animals. Furthermore, this warming process threatens temperature-sensitive species such as amphibians, insects and freshwater fish. In marine ecosystems, changes in temperature and increasing carbon dioxide levels cause ocean acidification. This threatens coral reefs, which are habitat for thousands of marine species. When coral reefs bleach, many species that depend on them for survival will lose their homes and food sources, potentially exacerbating the biodiversity crisis. Climate change also allows the emergence of new diseases and the spread of pathogenic organisms. Species exposed to new environments may not have natural immunity to certain diseases, leading to population declines. Additionally, new predators may emerge, resulting in disruptions in the food chain. Adaptation is the key to survival amidst rapid change. However, not all species can adapt quickly. Species with limited migratory capabilities and endemic species that cannot migrate will be particularly vulnerable. These limitations exacerbate already stressed biodiversity problems. Effective conservation policies are required to maintain remaining biodiversity. Protection of natural habitats, restoration of ecosystems and the establishment of protected areas are important steps to address the impacts of climate change. Public education about the importance of biodiversity and the role of humans in preserving it is vital. Reflecting on this situation, it is clear that global climate change is having a profound impact on biodiversity. Efforts need to be increased to increase awareness and act collectively in mitigation and adaptation. Success in maintaining biodiversity will depend on humans’ ability to adapt and maintain ecosystem balance amidst this great challenge.
