Sea Levels

 Over the last hundred years there has been a rise in the global sea level, there are many factors that contribute to this, ice glaciers have melted, due to climate change, thermal expansion has occurred in the ocean, human changes in storage of water on and under the land as well as other factors.

The input of sea level rise has come from the ice sheets in the Antarctica and Greenland and could account for one third of the present seal level rise which is around 2mm per year.

It is suggested that it is highly unlikely that this problem has come from natural factors; 2mm may not sound like a mass figure but it is enough to cause long lasting damage to different parts of the world. An even more dramatic figure is that sea levels will continue to rise between 10 and 90cm by 2100, the outcome of this is more natural disasters and millions of people left to flee their homes.
