Climate change is a global phenomenon caused by increasing concentrations of greenhouse gases in the atmosphere. The impacts of climate change are very diverse and significant, especially on ecosystems throughout the world. One of the main impacts is the increase in global average temperature. Higher temperatures affect natural habitats, causing changes in animal migration patterns and disrupting their reproductive cycles. In this regard, climate change also has an impact on biodiversity. Some species are forced to adapt, migrating to colder areas, or even risk extinction. Maritime ecosystems, such as coral reefs, are particularly vulnerable to high temperatures; Rising temperatures cause coral bleaching, which has the potential to damage entire marine ecosystems. For example, Coral Bleaching on Australia’s Great Barrier Reef shows that more than 50% of the coral has been lost due to extreme temperatures. Changes in rainfall patterns are also a significant impact of climate change. Some areas are becoming wetter, while others are experiencing severe drought. This affects the soil, causes erosion, and has a direct impact on agriculture. Certain crops, such as rice and corn, may have difficulty growing in uncertain weather conditions. Changing food production patterns has the potential to cause a food security crisis in various regions. Additionally, climate change impacts water systems. Increasing water temperature causes a reduction in dissolved oxygen, which is dangerous for aquatic biota. Furthermore, melting ice from glaciers and polar ice caps is raising sea levels, threatening coastal ecosystems such as mangroves, which are the refuge of many species. Extreme weather phenomena, such as stronger storms and increased frequency of forest fires, are also realities that must be faced. Wildfires not only burn vegetation but also disrupt animal habitats and release additional carbon dioxide into the atmosphere, accelerating the cycle of climate change. Ecosystem conservation is very important to mitigate the impacts of climate change. Efforts to protect and restore natural habitats must be carried out globally. Tree planting, wetland restoration and sustainable management are key to maintaining biodiversity and strengthening ecosystem resilience. Thus, understanding the impact of climate change on ecosystems is very important. Awareness to act immediately and involve the community in mitigation and adaptation efforts will help maintain ecosystem balance for future generations. Implementation of environmentally friendly policies and support for scientific research will accelerate our efforts to overcome the challenges posed by climate change.
