How does ocean warming affect climate change?
First of all, although we have been living on land, we should know that the ocean on the earth is the widest, accounting for 7 1% of the earth's surface area, and the specific heat capacity of seawater is much higher than that of other substances on land, which is the fundamental reason why the temperature difference between morning and evening in the desert is very large, while that in the ocean is very small. The thermal storage energy of the ocean is very powerful, and it is also one of the major factors affecting global climate change. We can simply understand that when the sun rises in the morning, it will cause the ocean to absorb a lot of heat and store it in it, and this heat will be slowly released when the weather is cold that night to ensure the relative temperature of the ocean is stable, although the energy consumed is still very large.
However, if the ocean warms, it will increase the heat returned to the earth's air in the form of long-wave radiation, latent heat and sensible heat, which will slowly lead to the change of air temperature, and then lead to the change of climate. However, it will definitely take a long time, and the temperature of the ocean will actually lose a lot, and the heat emitted into the air is also very small, that is, the heat emitted by evaporation of sunlight will enter the air to the greatest extent.
It's just that the hot spots of seawater are relatively high and it's generally difficult to evaporate. Moreover, rain will lead to the increase of seawater content, and finally more and more heat will be stored in seawater, which will eventually return to the earth's air through long-wave radiation, latent heat and sensible heat, so some warming can really affect climate change.
