What is the relationship between the salinity and density of ocean water?
BartSMP [9]
Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice.

How does carbon dioxide affect the ecosystem
FrozenT [24]

As a greenhouse gas that absorbs heat, CO2 raises the temperature of the atmosphere. We refer to this as global warming. The glaciers will melt more quickly as the world's temperature rises, raising sea levels and bringing on disaster. More power is consumed for air conditioning as the temperature rises, which further raises the air's CO2 level.

Since coal is the primary fuel utilized in the creation of power. This creates a vicious cycle.
