The "hockey stick" is just starting.
- Marine life: Warmer sea temperatures can lead to changes in the distribution and behavior of marine species, with some moving to cooler waters or changing their migration patterns. This can also affect the growth and reproduction rates of different marine organisms, which can have cascading effects on the food chain.
- Coral reefs: Coral reefs are highly sensitive to changes in sea temperature, and prolonged exposure to temperatures above 21 degrees Celsius can cause coral bleaching, which can lead to their death. This can have significant impacts on the many species that depend on coral reefs for food and habitat.
- Ocean currents: Changes in sea temperature can affect ocean currents, which can in turn impact weather patterns and climate. Warmer sea temperatures can lead to more frequent and severe weather events such as hurricanes and typhoons.

- Sea level rise: As sea temperatures rise, the water expands, contributing to sea level rise. This can lead to flooding and erosion in coastal areas and impact the livelihoods of people who depend on these areas for fishing and tourism.
- Decreased solubility: As sea temperature increases, the solubility of oxygen in seawater decreases. This means that warmer water holds less dissolved oxygen than cooler water. Therefore, as sea temperatures rise, the amount of oxygen available for marine life decreases.
- Increased stratification: Warmer water is less dense than cooler water, so as the sea temperature rises, the water column becomes more stratified, with warmer water sitting on top of cooler water. This can prevent oxygen-rich surface water from mixing with deeper water, leading to the formation of oxygen-depleted zones.
- Algae blooms: Warmer sea temperatures can promote the growth of certain types of algae, such as harmful algal blooms. These blooms can consume large amounts of oxygen when they decompose, leading to oxygen-depleted zones in the surrounding water.
- Oxygen-depleted zones, also known as hypoxic or anoxic zones, can have significant impacts on marine ecosystems. When oxygen levels become too low, many marine organisms, such as fish, shellfish, and crabs, can suffocate and die. This can have cascading effects on the food chain and lead to the loss of commercially important species. Additionally, the decomposition of dead marine organisms in these zones can release harmful gases such as hydrogen sulfide, which can be toxic to marine life and humans.
