How can global warming raise sea levels?

Question

Water expands 10% when frozen, so won't levels go lower when the ice caps thaw?

Answer 1

Some ice caps are not floating in the ocean. Greenland and Antarctica for example have ice on land. If they melt and flow down to the sea, that would cause sea level will rise. However if only the frozen north polar sea melted, sea level would not change, since all that ice is already floating in the sea.

Answer 2

Guess it depends on how high the ice is at the North & South Poles. And as it melts, and enter the world's oceans how much volume is being added?

Plus, that in snow top mountains and glaciers scatterred around the globe that are also melting.

Answer 3

even as the glaciers on the land melt into the sea the point will upward thrust. I actually have study that once 60% of the land ice on Greenland and Canada has melted, there'll be a dramatic upward thrust in the sea aspect. Surf the internet with keywords glacier melt and sea aspect upward thrust. verify the images and also you'll see maps of plausible results of sea aspect upward thrust. in case you verify the internet website international flooding you'll see some traumatic maps for 60 meter and one hundred meter rises. with any success this gained't ensue!

Answer 4

i think thats its because parts of the ice is above sea levels now.
but i dont believe that global warming is caused by humans and i dont think that it will be a major problem

Answer 5

If water expands 10%, then levels will go up (not down) when they thaw.

Answer 6

Yeah, but the difference is that when it is frozen, it stays in place, if it melts then it will all spread out therfore raising sealevels.

Answer 7

Yes it will, I am buying up lots of land on much higher ground for my children's children to be able to sell for ocean front property.Rich!! they will be rich!!
