@neiltyson everyone knows sea level rise is caused by boys throwing rocks into the ocean.

@neiltyson Are you sure? I’ve seen Waterworld, and it clearly shows a submerged planet due to ice caps melting. </sarcasm>Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson only for an instant...floating ice sheets keep glaciers on land held in place. Remove them, glaciers would surge forward.Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson actually that isn't quite true. Sea ice has less salt than sea water->melt has higher volume than displaced water->slight rise - 1 more reply

@neiltyson: If all the Arctic Ocean’s floating ice & icebergs melted, Earth’s sea level would remain unchanged.”@DavidCCoon@jernalist -
@BrianHarp@neiltyson@DavidCCoon Whaaaaat? We've been lied to? Can't be true!

@neiltyson If all the ice melted the sea gets fresher and freezes at a lower temperature and stops the currents and we get an Ice Age. -

@NickGamrath@neiltyson Yes higher temperatures - fresh water freezes at higher temperatures causing an Ice Age. -
@ThPeterLockhart@NickGamrath Both arguments have validity, but there's dramatically more variables at play than that. -
@Wright_Thoughts@NickGamrath We know fresh water freezes easier than salt water - the fresher the water at the poles the quicker it freezes -
@ThPeterLockhart Yes, I agree with that, but water freezing at a slightly higher temperature does not immediately conclude with ice age. -

@NickGamrath@Wright_Thoughts The science in that movie was pretty accurate to some degree. http://www.sciencedaily.com/releases/2004/12/041219153611.htm … - 1 more reply

@neiltyson Like a glass of water w/ice cubes, ice melts volume doesn't change, but what about glacier melt, and the Antarctic?Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson Hm. So where does the threat of rising seas come from? Ps, I believe you before the news outlets, which is why I ask.Thanks. Twitter will use this to make your timeline better. UndoUndo
