The impact of climate change on global biodiversity is an increasingly pressing issue in the modern era. Changes in temperature, rainfall patterns and extreme weather phenomena due to global warming have caused significant changes in habitats and ecosystems. One of the main impacts is the reduction of species. According to the IPBES report, one million plant and animal species face the risk of extinction due to climate change, apart from other factors such as deforestation and pollution. The increase in global average temperature affects the geographical distribution of species. For example, certain species such as fish and birds began to move to colder regions, disrupting local ecosystems. This can damage the food chain, because predators and prey no longer live in balance. Additionally, climate change is worsening lakes, rivers and oceans. Higher water temperatures cause increased algae blooms, which harm aquatic life and decrease oxygen in the water. Genetic diversity is also threatened by climate change. This reduces the species’ ability to adapt to new environments. For example, plant species that normally survive in a particular climate may not be able to survive if temperatures rise. A reduction in genetic diversity can lead to susceptibility to disease and pests, exacerbating the survival problem of the species. Climate change also affects interactions between species. For example, one species may start reproducing earlier because temperatures feel warmer, while other species that depend on it, such as nectar suckers, may not be as active yet. This timing mismatch can result in population declines and increased extinction. Ecosystem services, namely the benefits that ecosystems provide to humans, are also threatened. For example, climate change affects the supply of clean water, agricultural yields and food diversity. The loss of certain plant species can increase dependence on other crops, meaning there is a greater risk of crop failure. Conservation efforts are becoming increasingly important in dealing with the impacts of climate change. Initiatives such as the creation of ecological corridors help provide sustainable habitat for endangered species. In-depth research into the adaptation of species and their interactions in new climatic conditions is also urgently needed. Global entities, including the UN and environmental organizations, have developed various strategies to mitigate the impacts of climate change. Stricter international policies regarding greenhouse gas emissions, as well as reforestation programs, are intended to reduce the rate of global warming and its impact on biodiversity. At the local level, community involvement in environmental conservation is very important. Education about the importance of biodiversity and its impacts can increase awareness. Communities can play an active role in species conservation and habitat restoration through sustainable natural resource management programs. As the climate changes, new challenges arise for all living things. We must move quickly, united in efforts to protect precious biodiversity. Collective action, both at the local and global levels, is essential to ensure that the earth remains a welcoming home for all species in the future.
