Global climate change refers to the warming of the earth’s average temperature caused by increasing concentrations of greenhouse gases (GHG), such as carbon dioxide (CO2) and methane (CH4). This phenomenon has a significant impact on biodiversity, which includes various plant and animal species, as well as the ecosystem as a whole. One of the main impacts is habitat change. With shifts in temperature, many species are forced to adapt or move to more suitable locations. For example, mountain species may move to higher altitudes or to northern latitudes. Changing weather patterns also affect biodiversity. Irregular rains and the increasing frequency and intensity of natural disasters, such as floods and droughts, disrupt the life cycles of species. Many species depend on specific conditions for reproduction and survival, so these changes can trigger local extinctions. In addition, climate change has implications for interactions between species. Predation, competition, and symbiotic relationships can be disrupted, further affecting the overall balance of the ecosystem. Biodiversity levels in tropical ecosystems, such as the Amazon rainforest, are highly vulnerable to the impacts of climate change. In these regions, higher temperatures and increased CO2 may cause shifts in species composition, resulting in the loss of some species and the proliferation of invasive species. In the ocean, warming and acidifying seawater threatens coral reefs, which are important habitats for many species. With the destruction of coral reefs, not only marine organisms are threatened, but also communities that depend on reef fish for food and the economy. Apart from that, loss of biodiversity also has an impact on ecosystem resilience. Species-rich ecosystems tend to be more resilient to disease and environmental change. When species diversity decreases, ecosystems become more vulnerable to disturbance, which can lead to a decline in ecosystem function. This includes providing essential services such as carbon storage, water cleaning, and plant pollination. Therefore, protecting biodiversity is key in efforts to mitigate climate change. Global climate change also has an uneven impact. More vulnerable areas, such as small islands and coastal areas, face greater risks. Species that do not have high mobility, such as many fish and amphibians, are at higher risk of extinction. Required mitigation measures include reducing GHG emissions, protecting habitats, and sustainable management of natural resources. This effort requires global cooperation and awareness of the importance of biodiversity for the health of the planet and people. It should be noted that education and raising public awareness regarding the relationship between climate change and biodiversity is essential. Through educational campaigns, the public can better understand the need for conservation and support pro-environmental policies. Community involvement in conservation activities can also help increase ecosystem resilience to climate change. Proactive responses to these challenges will largely determine the future of biodiversity and the health of the planet as a whole.
