According to several scientific surveys, the ocean level has been rising
at a rate of 3.5 millimeters per year in the last 25 years. The
question which arises is whether this fact is a consequence of global
warming or some other causes could be held accountable for it as well.
It has been noticed lately an increase in number and intensity of
several catastrophic events such as hurricanes and tornadoes. They also
start to be present in some areas where they were not reported before.
The relation between these phenomena and climate change is yet not fully
established.
It is usually accepted that climate change happens and affects oceans
and Earth as an ecosystem. This further may endanger the lives of the
animals in areas around the North and South Poles.
It is usually accepted that climate change happens and affects oceans

various countries and ultimately the lives of the people living there.
With the highest elevation of 4.6 meters, the state of Tuvalu in the
Pacific Ocean is one of the countries with the lowest maximum elevation
on Earth. This makes it extremely vulnerable to sea level rise, which
can lead to land loses and, by extrapolation, to the sinking of the
whole national territory. It is not clear how this could be avoided.
Sea surface level measurements in the last 120 years show an increase of
the average temperature of the water. However, some people believe the
data are neither accurate nor complete so we cannot say the sea water is
getting warmer all over the world.
