Climate change is a global phenomenon characterized by an increase in the Earth’s average temperature due to human activities, especially greenhouse gas emissions. The impact of climate change on global biodiversity is very significant and covers various aspects, from habitat changes to reductions in species populations. One of the main impacts of climate change is habitat change. Rising temperatures, changing rainfall patterns, and other extreme phenomena are forcing many species to move to more comfortable areas. For example, species in cold regions such as the poles are finding their habitats shrinking, while tropical species are also struggling to survive in increasingly hotter conditions. Climate change also worsens the condition of already fragile ecosystems. Corals, for example, experience bleaching due to high sea temperatures and increased water acidity. The loss of coral reefs not only impacts underwater life but also the communities that depend on fish for food and livelihoods. On land, climate change is resulting in an increase in the frequency and intensity of forest fires. Damaged forest ecosystems accelerate the loss of species that are an integral part of biodiversity. These species are unable to adapt quickly to the changes that occur, giving rise to a higher risk of extinction. Climate change also affects interactions between species. This phenomenon can disrupt the food chain and life cycle of certain species. For example, if plants bloom early due to warm weather, animals that depend on those plants for food will not find enough food sources, resulting in a population decline. The influence of climate change on animal migration is also very real. Many bird species are changing their migration patterns, seeking places that better suit their living needs. This not only affects bird populations but also other species that are predators or prey of these birds. Global warming also provides opportunities for invasive species to spread to new areas, endangering local species. They are often more aggressive in competing for resources, taking over native habitats, and spreading new diseases. Meanwhile, the impact on biodiversity can already be seen with reports of a decline in the number of species in various parts of the world. This decline not only touched rare species, but also seemingly common types. This warming planet has the potential to wipe out genetic diversity that is vital for ecosystem resilience and future evolutionary potential. Various studies show that ecosystem units that are richer in biodiversity are more resistant to change and damage. However, with the loss of species, ecosystems become weaker and vulnerable to further change. Therefore, a coordinated global response and addressing this issue holistically is essential to minimize the impact of climate change on biodiversity. Scientists call for a comprehensive mitigation strategy to address the underlying causes of climate change. Approaches that include habitat conservation, sustainable resource management, and increasing public awareness of the importance of biodiversity will be essential for us to protect global biodiversity in this era of climate change.
