Good morning, everyone. Today we're going to discuss the impact of climate change on marine ecosystems. A recent study by the University of Sydney found that rising sea temperatures have caused a significant decline in the population of kelp forests along the eastern coast of Australia. These kelp forests are crucial habitats for many fish species. The study also highlighted that ocean acidification, not just warming, is a major threat. However, the researchers noted that some kelp species are showing resilience in cooler, deeper waters. This suggests that conservation efforts should focus on protecting these deeper refuges.
