Records in temperature are being achieved in the seas around the globe. There are evidences that South Atlantic waters are warmer, which increases the possibility of hurricanes in South America. This is occurring because of the greenhouse effect, which is the retention of long wave radiation that the planet relays back to space to maintain the thermodynamic equilibrium. With increasing concentration of gases that produce the greenhouse effect, it is captured a greater amount of heat and this heat eventually warms the atmosphere and the ocean itself. Excessive heat in the ocean surface will be transported by a circle movement; these movements are water going toward the bottom and to other areas, in such a way that over time we will have a global temperature rising in ocean.
Oceans have a higher heat capacity than the rest of the system, it makes these changes happens slowly, which might allows us to adapt to change. As a result we will have the increasing in the sea level. Either by volume expansion or in mass due to melting polar ice caps or ice continent. Another effect also important is that the sea water is basic; increasing the temperature - due to increased CO2 in the atmosphere - will increase the acidity of water and will translate into a very drastic interference in the ecosystem. Starting with, reduction in biodiversity. Not to mention that with the increase in acidity, we will have ocean reduced ability to absorb CO2. The increasing in ocean temperature also changes its pattern of movement triggering changing in how the ocean contributes to the redistribution of heat by modifying the temperature of some regions. Some areas will be cooler than they are today and others will be warmer. A study made by researchers from Germany and South Africa shows that a change has occurred already in the pattern of atmospheric circulation in the South Atlantic due to the increased import from Indian Ocean to South Atlantic, it hasn't been known the intensity and which areas are actually affected, but surely something is coming.
