As we already know, the 4 oceans are salty. This so called salinity is about 35 grams of sodium chloride per 1 kilogram of seawater. It basically encompasses
approximately 35% of our oceans. I have learned that
the average freezing point of seawater is around 28.4 degrees or -2 degrees in centigrade. But however with the salinity(salt), if it increases then the temperature at which seawater freezes goes down. If less salinity is added, for example: The fresh water from melting glaciers, then the freezing level of the oceans increases. Too much fresh water will inhibit a global climate change.
