Climate change is a condition characterized by long-term changes in temperature and weather patterns on earth. This phenomenon has a significant impact on biodiversity, which includes all forms of life, both flora and fauna. For example, increasing global temperatures can affect natural habitats, species distributions, and overall ecosystems. The most obvious impact of climate change is the increase in global average temperature. Higher temperatures can cause warming of the oceans and melting of polar ice, resulting in rising sea levels. This threatens species living in coastal areas, such as seagulls and sea turtles, which depend on coastal habitats that are increasingly being lost. Changes in rainfall patterns also contribute to ecosystem changes. Previously fertile areas may experience drought, while other areas may be flooded. This weather instability affects the migration patterns of animals, especially bird species, which depend on time and place to follow their food cycles. In addition, plants that depend on certain rainfall also experience difficulty in adapting, potentially reducing food security. Rising temperatures and changes in rainfall pose challenges for species that cannot adapt quickly. Many species are experiencing population decline or even becoming extinct due to the loss of their natural habitat. For example, amphibian species are experiencing drastic declines worldwide as a result of habitat loss and rising temperatures that encourage the spread of disease. Climate change also drives geographic shifts in species. Many animal and plant species began to move towards colder areas, such as mountains or polar regions. These shifts can cause conflict between new and native species, disrupting the balance of local ecosystems. For example, newly emerging invasive species can dominate existing habitats, destroying native species and reducing biodiversity. Marine ecosystems are also affected by increasing temperatures and ocean acidification. Coral reefs, which are important habitats for thousands of marine species, are increasingly threatened by global warming and pollution. Coral reef bleaching is a serious problem that impacts biodiversity, as coral reefs provide shelter and food sources for many marine organisms. The impact of Jakarta, as a city vulnerable to flooding, also shows the direct relationship between climate change and biodiversity. Land deforestation and infrastructure development lead to habitat loss, further crowding out local species and reducing biodiversity. Limited conservation efforts in urban areas often make the situation worse. Globally, humans’ role in exacerbating climate change must be acknowledged. Greenhouse gas emissions, deforestation and industrial activities cause habitat destruction and create extreme climate change. To protect biodiversity, better prevention and adaptation measures are needed, including habitat restoration, emission reduction and sustainable management of natural resources. Facing a more uncertain future due to climate change, education and awareness about the importance of biodiversity is key. Together, conservation efforts can help protect threatened species and maintain ecosystem balance, so that biodiversity can be maintained for future generations.
