Which of the following is a potential consequence of climate change on marine environments?

• A. Decreased frequency of extreme weather events
• B. Rising sea temperatures and ocean acidification
• C. Increased coral formation
• D. Lower resilience of marine species

Answer: (B)

Rising sea temperatures and ocean acidification are significant consequences of climate change on marine environments. As the Earth's climate warms due to increased greenhouse gas emissions, ocean temperatures rise, leading to various ecological impacts. Warmer waters can stress marine organisms, disrupt food webs, and alter species distributions. Additionally, the oceans absorb a large portion of carbon dioxide emissions, resulting in ocean acidification. This process lowers the pH of seawater, negatively impacting calcifying organisms such as corals, mollusks, and some plankton species that rely on calcium carbonate for their shells and skeletons. This combination of rising temperatures and acidification poses severe threats to marine biodiversity and ecosystem health, including coral reefs, which are particularly sensitive to these changes. The other options suggest scenarios that do not align with the current scientific understanding of climate change impacts. For instance, decreased frequency of extreme weather events is contrary to the observed increase in the severity and frequency of storms due to climate change. Increased coral formation is unlikely as warmer temperatures and acidification typically lead to coral bleaching, which reduces coral health and reproduction rates. Lastly, the lower resilience of marine species is a result of the stressors associated with climate change rather than being a direct consequence itself, making the chosen answer the
