Carbon Dioxide (CO2) is the primary greenhouse gas responsible for the majority of global warming, contributing significantly to the rise in Earth's average temperature.

Climate change leads to increased levels of carbon dioxide in the atmosphere, which dissolves in the ocean and forms carbonic acid. This results in a decrease in pH and an increase in ocean acidity.

Coral bleaching refers to the phenomenon where corals lose their vibrant colors and expel the symbiotic algae that provide them with nutrients and energy. This process is primarily caused by elevated sea temperatures and other environmental stressors.

Climate change contributes to sea level rise through various mechanisms, including the thermal expansion of ocean water as it warms, the melting of glaciers and ice sheets, and the potential increase in precipitation and runoff.

Oysters, clams, and mussels are all marine species that are particularly vulnerable to the effects of ocean acidification. These organisms rely on calcium carbonate to build their shells, and increased acidity makes it more difficult for them to form and maintain their protective structures.

Migration refers to the movement of marine organisms from one location to another in response to changing environmental conditions, such as rising sea temperatures or shifting food sources.

Coral reefs are particularly sensitive to the effects of climate change, especially rising sea temperatures and ocean acidification. They are often referred to as the 'rainforests of the sea' due to their high biodiversity and ecological importance.

Adaptation refers to the process by which marine organisms evolve new traits or characteristics that allow them to better survive and reproduce in changing environmental conditions, such as rising sea temperatures or ocean acidification.

Climate change can cause shifts in species' ranges and abundances, as they move to new locations or experience changes in their reproductive success and survival rates due to altered environmental conditions.

Acclimatization refers to the process by which marine organisms adjust their behavior or physiology to better cope with changing environmental conditions, such as rising sea temperatures or ocean acidification, without necessarily evolving new traits.

Sea turtles, polar bears, and manatees are all marine species that are particularly vulnerable to the effects of sea level rise and coastal erosion, as these changes can impact their nesting sites, habitats, and food sources.

Climate change can lead to an increase in the frequency and intensity of extreme weather events, such as hurricanes, cyclones, and storm surges, which can have devastating impacts on marine ecosystems and coastal communities.

Evolution refers to the process by which marine organisms evolve new traits or characteristics over many generations in response to changing environmental conditions, such as rising sea temperatures or ocean acidification.

The impact of climate change on marine productivity can vary depending on the region and the specific ecosystem. Some areas may experience increased productivity due to factors like warmer waters and longer growing seasons, while others may experience decreased productivity due to factors like ocean acidification and habitat loss.

Migration refers to the movement of marine organisms from one location to another in response to changing environmental conditions, such as rising sea temperatures or shifting food sources.
