How does the thawing of ice that floats on water affect sea levels in any way?

...and the north pole caps being gone in Winter? Does he have any idea how nutty that is?

He obviously has not contemplated Archimedes.

"How does the thawing of ice that floats on water affect sea levels in any way?"

It doesn't. Did you ever sit on the deck with a glass of ice water? As the ice melts the level of the water does not change. To call Al Gore an idiot is doing him a kindness.

Actually, if global warming were to occur; the oceans would rise from the thermal expansion of the water -- everything else being equal.* (Please note; I'm in no way trying to defend Gore. A glance at a few of my numerous posts on this topic would tell you what I think of Gore and his ilk.) * It's actually more complicated than that -- water has the unique property of expanding when it warms avove, or when it cools below 3.98*C. If it weren't for that feature, our oceans would probably be solid ice by now. If the oceans warmed, some of the water would contract; but, most of it would expand. The polar oceans might be an exception (getting smaller, overall).

Archimedes proved that an object displaces its mass in water if it is less dense that water and its volume if it is more dense. As ice is less dense it will displace its mass which being water will not cause a change in sea level if it melts. This is something learned in Physics 101

The increase in sea level that is proposed to come from global warming does not come from the melting of ice that is floating on water, but from ice that is either on land or resting on the sea floor.

Gore may say some nutty things, but somehow I doubt that an Arab website called maktoob.com is the most accurate source for what he really said this time.

Liberals don’t need no stinkin’ facts, theys got “feelings”...

From 8th or 9th grade Earth science ...... learn what the term “isostacy” means relevant to rise in sea levels. Think about an ice cube melting in a glass. It may be pertinent to the discussion to learn about continental ice sheets and sea levels say when the Wisconson glacier covered a good portion of north america. How much of the world’s fresh water is currently locked up in terrestrial ice sheet and why is this important to agriculture, surface water resources and ground water recharge? How many millions of ft3 are bound up in terrestrial ice now, and at what rate is it declining? and why is this relevant?

Can say, the Hudson River’s delta be found in a location that is congruent with sea levels 18000 years ago. What forms geological features such as Fjords? Again, think bout isostacy because I detect a lot of missing information based on your comments.

Further, IF the science is completely wrong and the climate change that we are currently experiencing is due to natural processes yet to be adequately explained by researchers, at what point do we consider energy alternatives in light of known current fossil fuel reserves?? How long can our decedents expect to use what is left of these reserves? and how is this relevant to current population growth curves? Do you have any predictions of the challenges facing those living in a world of 9 billion plus people? Or will some deity finally step in an provide a solution for future humanity? just wondering
