Melting ice threatens sea-level rise
Here's why. Water is one of the only materials that when it freezes, it expands. Thusly, when it melts, it contracts. For instance, if you fill a glass with water and put an ice cube in it then wait for the ice to melt the water level actually goes down.
This is where the environmental movement ceases to hold water (pun intended). Because, as I have stated above, the rise of sea levels cannot be the result of polar melting. Melting icebergs and icecaps (The North Pole being the warmer of the two would be the first to melt which has no land mass under it like the South Pole) would then cause a recession of waters along the coasts.
It is, then, global warming (if it existed) that is keeping the oceans from rising to dangerous levels!
