<human>:  How does climate change affect the ocean?
<bot>: Climate change is having a significant and increasing impact on the ocean. Due to higher air temperatures, ocean temperatures are rising, resulting in drastic changes in ocean chemistry. This causes increased acidification, decreased oxygen levels, and changes in the diversity, abundance, and distribution of marine species. Additionally, rising sea levels is a major threat to coastal habitats, exacerbating erosion and flooding. These changes can have devastating impacts on coastal communities and the global ocean ecosystem.
