An Interesting Experiment

Recalling my education in basic science and physics, I tried the following experiment. I would encourage each of you to do the same, if only to prove something to your own satisfaction, and provide you with some peace of mind.

Place two or three ice cubes in a glass, and place the glass on a napkin or paper plate on a perfectly level surface. Now, CAREFULLY fill the glass with water, right to the very brim. Be careful not to overfill it, and get the napkin or paper plate wet. But also use care not to underfill it. The water should be right at the very brim of the glass.

Now, go away. After the ice has had time to melt, go check on the glass. If the napkin or paper plate is wet, the glass overflowed when the ice melted. If the napkin or plate is dry, then the glass did not overflow.

If you do this correctly and carefully, you will discover that the water in the glass did not overflow, even with the "addition" of the water from the melted ice.

How can that be? It is because water contracts when it freezes, and takes up less space. If you really want to take more precise measurements, you will find that after the ice melts, the water level may actually go down just a hair.

So, just what is the point of this simple experiment?

A lot of so-called "scientists" are trying to scare you into putting money into global warming projects, telling you that unless you do this, the ice fields will melt and flood all coastal areas and cities, causing mass destruction and catastrophy.

But you have just proven to yourself that if the ice melts, it will NOT raise sea level one iota. If anything, it may actually lower them a bit.

This is not to say sea levels may not rise. What this experiment does prove, however, is that they will not rise because the ice melts, EXCEPT for that ice which is landlocked. Landlocked ice could raise water levels, but most ice in the northern hemisphere is NOT landlocked ice. There is no land mass under the arctic. And the ice that is landlocked over the Antarctic at the South Pole is actually thickening, and not melting.

Why is that? Most real scientists who look at the overall picture as to what contributes to warming and cooling can tell you that the Earth is an elliptoid, not a true globe. And its axis moves - the Earth wobbles in its orbit around the sun. Spin a top, and watch as it starts to wind down. And there are periods when the northern hemisphere points to the sun, and periods when the southern hemisphere points toward the sun. Right now, and for the best part of the last century, the northern hemisphere has been sunward. So, while the ice to the north melts, the ice to the south thickens.

At least, that is one logical premise.

The point is, it would appear from our little experiment that if all the ice on the planet were to melt all at once, it is unlikely it would cause sea levels to rise more than 1 to 3 feet at the most - and probably not even that much.

Ya know, if you use the same theory and experiment, using a taller glass and whisky with three ice cubes, making sure only to let the cubes chill the liquid not to water it down, you won't give a crap about global warming,Al Gore or have the ability to say scientist
