The Rising of the Oceans. Ho Hum

I believe we are being told too many untruths

Some of the theories surrounding global warming suggest in time to come the oceans will rise about 100 feet as a result of the ice caps melting making much of our habited land a sea bed.

One of the unusual properties of water is that as it cools and becomes solid (ice) it expands. This is why icebergs float. As ice melts, the volume shrinks.

Here’s an experiment you can try at home. I’ve spent some time trying to calculate a model of earth in a bath, with an appropriate amount of water and artificial land, but it’s not necessary.

Take two or three iceblocks from the freezer and place them into a container, a used coffee jar is ideal, leave the label on as a reference. Now slowly add water to raise the level to the top of the label or other mark.

Now watch the ice melt. This is as exciting as watching paint dry. Put the lid on the container so no water vapour can escape and do something else if you like.

How much did the water raise as the ice melted?

So, the melting of floating ice will not raise the sea level.

Now, lets have a look at Antarctica, Alaska, Northern Europe, Russia, any ice that is above sea level on land. (The Arctic is floating, so I’ve been told, and Russia surprised the US Defence experts by sailing a fleet of submarines under it, as I have read)

For the sea level to rise 100 feet as a result of ice melting what is required is an area of land equal to the area of sea water with ice at an average height of 100 feet.

Where on Earth (literally) is that amount of ice?. The surface of the oceans accounts for about 71% of the total surface area of the Earth.

Thank you for your well detailed response. I can tell you have a genuine interest of the subject to be able to quote so much from that poster. The graph mentioned sounds to be the infamous "J curve" which has caused much debate.<br />
<br />
From the Cambridge Encyclopaedia of Earth Sciences comes this graph. <br />

<br />
Admittedly, the data used would have been derived from calculations rather than actual measurements. However, the figures arrived at for the time 500 Million years ago are similar to current measurements. I.E. Nitrogen at 80% and Oxygen at 20% by weight of the total atmosphere.<br />
<br />
In 1945 the composition of Earth's atmosphere was reported as: <br />
<br />
Nitrogen 75.5% <br />
Oxygen 23.2% <br />
Argon 1.3% <br />
Carbon Dioxide 0.05 - 0.4% <br />
Krypton 0.28% <br />
Xenon 0.005% <br />
Neon 0.00086% <br />
Helium 0.000056%<br />
Source: Chambers Technical Dictionary, revised edition 1945<br />
<br />
From Wikipedia:<br />
<br />
Nitrogen (N2) 780,840 ppmv (78.084%)<br />
Oxygen (O2) 209,460 ppmv (20.946%)<br />
Argon (Ar) 9,340 ppmv (0.9340%)<br />
Carbon dioxide (CO2) 390 ppmv (0.039%)<br />
Neon (Ne) 18.18 ppmv (0.001818%)<br />
Helium (He) 5.24 ppmv (0.000524%)<br />
Methane (CH4) 1.79 ppmv (0.000179%)<br />
Krypton (Kr) 1.14 ppmv (0.000114%)<br />
Hydrogen (H2) 0.55 ppmv (0.000055%) <br />
<br />

<br />
Note that Wikipedia make no mention of the fact that CO2 concentrations vary throughout the year and just quote less than that reported in 1945. Less CO2 is absorbed by plant life during the dormant season.<br />
<br />
To me, the more alarming fact is the reduction in free oxygen (23.2% down to 20.946% in 65 years)<br />
<br />
The only man made cause for this that I am aware of is due to the reduction in plant life (deforestation) so we have reduced the ability to recover the oxygen from carbon dioxide (photosynthesis) <br />
<br />
As for carbon dioxide being a green house gas, I don't agree. CO2 is heavy compared to oxygen. It falls to the ground. If it rose to the upper atmosphere and stayed there the earth would become desolate without plant life, and very soon after, no life at all.

There is something I feel compelled to share on this issue. Since I'm home as I write this and my source for this one fact is a National Geographic poster in my office I cannot quote any numbers but I welcome all and anyone to contact me for more info and I will be pleased to provide as much as I can. In fact, just now I decided to agenda a mini project to later add specifics and numbers to what I will tell you herein and post that as a blog or other format on EP. In so doing I will also cull pertinent URLs into a list that I will include as part of the writing.<br />

Through taking a great many of very deep core samples from particularly the most solid of permanent (thus far) ice and deeper substrates at and around the two polar regions of this planet, We (the professional collective I call 'science' for lack of better name) have been able to chart the concentrations/amounts/levels of CO2 present in the ambient air as far back as multiples of millions of years. This was done so thoroughly and in such a manner via international and multidisciplinary collaboration and cooperation as well as unprecedented la<x>yers of checks and balances that no potential private, personal, corporate or government etc. agendas could possibly influence the factual findings of the research. Hence, We have an actual graph (the Nat Geo issued poster in my office contains this graph as well as same in graphs for/of a few other variables such as ambient temperature) of the history of the ambient CO2 concentration of Earth's immediate atmosphere from almost when this planet was formed clear through to today. This was how we found out that yes, the ambient CO2 concentrations have indeed risen and fallen in a cyclic trend 'naturally', long before there was any industrial and even the most primitive activity of humans on Earth. The cycles repeat consistently on the graph and each cycle is of hundreds of thousands of years long. From the beginning of this graph up to the start of the human industrial age/activity the highest ambient level of CO2 in each cycle has been relatively consistent in every cycle as are the graphs for ambient temperature and the other measured variables. Some time after the start of the industrial age, the ambient CO2 levels began to rapidly increase so significantly that the graph line at that time in history is several times (100% increases) higher than the highest point of each cycle and it has NEVER fallen since and it now depicts an exponential upward 'curve' that appears on the graph more like a vertical line rather than any curve at all. THE AMBIENT CO2 LEVEL TODAY, 12/6/2010, IS AT LEAST TEN TIMES (1,000%) GREATER/HIGHER THAN THE GREATEST/HIGHEST LEVELS THAT HAVE EVER BEEN PRESENT IN THE HISTORY OF THE PLANET and on that CO2 graph, at the date of 12/6/2010, the CO2 level graph line is, from the start of the industrial age through today, a vertical line that is most obviously and unquestionably NOT NATURAL.

Frig it must have been an epic journey under the Artic ice mass I wonder if there is any video footage it would be awesome to view I am going to have a look on the geology.com website I am intriged

Hmmmm .. !!

Yep, crazy, like swine flu.

Crazy story!!

Poor penguins!

It is nothing to laugh at datura ... get your ice blocks and coffee jar and see for yourself.<br />
<br />
Penguins will have to learn to nest in trees!

hahahahahahahahahaha

All animals should be saved. They didn't ask to be born just like humans.
