Did you know?

Hi Again,

‘Rising Sea Levels’ is something you all have heard. Let's find out what ‘Rising Sea Levels’ mean, what really happens? Well...... can water really raise itself? Questions? Questions??

Let's watch this short video and see if we can find answers to the above questions...... I am sure you will be intrigued watching this clip........

I found my answers watching the video.

Here are my answers..... have you got yours ready to compare!!!!

•       There are two factors for the sea to rise

1.  The ocean waters are being heated due to warming of the climate. Heating of water makes the volume of water to expand. This causes sea levels to rise.

2.  Melt water of land and marine ice sheets and glaciers adds into the oceans. This melting of the ice sheets happens above and below sea level. Melting of the marine ice sheet underneath the surface of the sea cannot be seen. This occurs when a column of warm water from the tropics flow underneath the surface of the sea and touches the marine ice sheet. The ice sheet begins to melt triggering the land based ice sheets to move towards the open oceans.

Sea level rise endangers 10% off the world’s population to date.  Scientists predict up to 5 to 6 m of sea level will rise in the years to come, with an annual increase of at least 10mm/yr within 200 years (Richard et al., 2006).

Megacities situated near coastal areas, home to around 5 million people will have to migrate inland. Abandoning their homes, facing job loss leading to economic loss will bring great strain to these coastal areas causing economic and political chaos (Richard et al., 2006).

So, shall we abandon or adapt our lifestyles and homes to live in this becoming ‘water world’
Good bye, until next time..............
