query: What are the effects of climate change on oceans?
answer: Climate change significantly impacts oceans, causing sea level rise due to warming and ice melt, ocean acidification from increased CO2 absorption, changes in ocean currents and stratification affecting oxygen levels, and devastating effects on marine ecosystems like coral reefs (bleaching).  Warming also alters weather patterns, including increased cyclone intensity and changes in rainfall patterns.
