How does the greenhouse effect impact ocean temperatures?

The greenhouse effect significantly impacts ocean temperatures by causing warming oceans, which directly contributes to coral bleaching. This warming occurs as greenhouse gases, such as carbon dioxide and methane, trap heat in the Earth's atmosphere. As the atmosphere heats up, the oceans absorb much of this excess heat, leading to higher water temperatures.

When ocean temperatures rise, marine ecosystems, especially coral reefs, become stressed. Corals have a symbiotic relationship with zooxanthellae, the algae that provide them with nutrients through photosynthesis. Elevated temperatures can cause corals to expel these algae, leading to a phenomenon known as coral bleaching. When corals are bleached, they lose their color and are more vulnerable to disease and mortality.

Understanding the connection between the greenhouse effect and ocean temperature is critical for predicting the future of marine environments and the conservation efforts needed to protect vulnerable species and habitats.
