"Please think about the amount of ENERGY needed to melt any significant amount of ice,
If you drop an ice cube or just about any substance with mass into a FULL glass of water of course it will over flow"

The point is not that the glass "overflows", but that the water level rises when ice floats in it. The amount of energy required to MELT the ice is entirely irrelevant, since the ice doesn't need to melt to cause the sea level to rise. The only energy needed is that to melt the surface of the glacier, to give the layer of lubricating liquid. The glacier itself does not need to melt more than this amount.

" "Science" is about questioning as any real scientist will agree, that is what I am about, I have NOT seen enough real evedience to convince me that the speculation about Global warming is a fait-accompli"

Absence of evidence is not evidence of absence. Just because you personally haven't seen it doesn't mean it doesn't exist.

What is the relevance of "benefits" of global warming? There are also grave disadvantages to climate change, which are becoming increasingly apparent world wide. CSIRO mentions them.

"the only plausible explanation is that there was a rise in the land mass, and that will explain a lot of the sea fossils found miles inland."

There is more than one "plausible" (as opposed to acceptable to you) explanation for the fossils. Given that although you seem accept the possibility of the land rising (geological science is acceptable, but not climate science?) there is still the question of where the water displaced by the volume of the land has gone.

"Personally I have no problems with a rise in winter temperatures, extra heat in summer has not caused me any problems in the past, I have worked in confined spaces far hotter than the projected temperatures, and given the time frame that all of this is supposed to happen, we will all adapt"

If the sea level rises even a small amount, the water will cover more land, increasing the sea's surface area, which in turn will capture more solar energy, making the oceans warmer, which, inter alia will increase the intensity of cyclones. This is a global problem, not just a matter of your own personal comfort.
