From the Scientific American "Ask a Question" page.
Recent NASA photos showed the opening of the Northwest Passage and that a third of the Arctic’s sea ice has melted in recent. Are sea levels already starting to rise accordingly, and if so what effects is this having?
In their response they talk about the Greenland, West and East Antarctic ice sheets (which would indeed cause problems for sea levels):
“That may not sound like a lot, but consider the volume of ice now locked up in the planet’s three greatest ice sheets,” she writes in a recent issue of Scientific American. “If the West Antarctic ice sheet were to disappear, sea level would rise almost 19 feet; the ice in the Greenland ice sheet could add 24 feet to that; and the East Antarctic ice sheet could add yet another 170 feet to the level of the world’s oceans: more than 213 feet in all.” Bell underscores the severity of the situation by pointing out that the 150-foot tall Statue of Liberty could be completely submerged within a matter of decades.
Decades? Look, for this sort of thing to happen, even under the worst scenarios, we\’re talking sometime between 2500 AD and 2700 AD.
And, perhaps more pertinently, nowhere do they make the point that the Arctic ice largely sits upon the ocean already meaning that the melting of such ice does not impact sea levels at all (subsequent thermal expansion might, but not the melting itself).
I realise that it\’s a fairly harsh charge to level at a magazine like Scientific American, but this is simply lies.
No, this isn\’t just me being a sceptic or anything, this is so far from the scientific consensus that it\’s passed over into the realms of pure moonbattery. It\’s shameful, deeply so, that a purportedly scientific magazine should publish such tripe.
