Higher sea levels result primarily from the melting of polar ice caps and glaciers, as well as the thermal expansion of seawater due to global warming. This phenomenon can lead to increased coastal flooding, erosion, and the displacement of communities living in low-lying areas. Additionally, higher sea levels can disrupt ecosystems, affect freshwater supplies, and pose challenges to infrastructure and agriculture. Overall, the consequences are significant for both human populations and natural environments.
Sea levels have fluctuated throughout geologic history, sometimes being higher and sometimes lower than they are today. During periods of glacial melting, sea levels were higher, while during ice ages, sea levels were lower due to water being locked up in ice sheets. Currently, sea levels are rising due to global warming and melting ice caps.
The saltiest sea is the Red Sea, with higher salinity levels than the world's oceans due to its high evaporation rate and limited connection to other bodies of water, preventing significant dilution.
The increase in CO2 concentration in the atmosphere leads to higher global temperatures through the greenhouse effect. This causes ice sheets and glaciers to melt, adding more water to the oceans and causing sea levels to rise. Additionally, warmer water expands, further contributing to the rise in sea levels.
As glaciers and ice caps recede, they contribute to rising sea levels through the melting of ice and the subsequent addition of water to the oceans. This process leads to higher sea levels, which can result in coastal flooding, erosion, and the displacement of communities living in low-lying areas.
Atmospheric pressure decreases as you move up away from sea level. This is because there is less air above pushing down on you the higher you go. This change in pressure can lead to lower oxygen levels at higher elevations.
Rising from the sea level to the higher levels will result in decrease of temperature and pressure.
Water expands when it warms. So sea levels rise.The Antarctic ice caps melt as a result of global warming. This puts more water into the oceans thus raising sea levels.

Melting of glaciers.
In so far as global warming will decrease the amounts of polar ice, that melted water does result in a higher Sea Level. National Geographic June 2011 - Earth 56 million years ago - Sea Levels 225 feet higher than now.
The density of salt water is higher than fresh water.
precipitation equals rain. As when sea water evaporates clouds form eventually leading to rain fall refilling the sea with the previously evaporated water. But not all rain water returns to the sea which is how the sea level changes due to precipitation.
If polar ice masses melt due to global warming, sea levels will rise, leading to more frequent and severe coastal flooding. This can have significant impacts on coastal communities, ecosystems, and infrastructure. Efforts to mitigate climate change are crucial to prevent further sea level rise.
contamination of air, overgroth of plants, increased chances of fires, higher sea levels, more carbon dioxide (from fires), lower sea levels as the CO2 gets even higher, eventually if the trend continues you will have either a Mars or Venus left of Earth.

It lived exclusively in Argentina. At this time Argentina was surrounded by water as sea levels were much higher during this time.
