Antarctica is still a continent. But you think glaciers scraped the continent off to levels below sea level. Wow... You have no science education whatsoever, do you. I'd like you to picture what sort of topology would be required for a glacier to scrape rock off 2.5 km deep.Antarctica was once a complete continent 50 million years ago, and as we see below, WAS ATTACHED to South America. Ice age glaciers scrape off what is "loose" on a continent. They only leave bedrock and mountains. Most of the "surface" of Antarctica today is below sea level. That was not the case 50 million years ago. And, hilariously enough, the image has the caption "Lately (ie the past 40+ million years) it (AA's ice) seems to be thickening - BECAUSE OF GLOBAL WARMING.
Ice thinning = Global Warming
Ice thickening = Global Warming
EVERYONE GOT THAT!!!
Morons - anyone who thinks there is any real "Science" involved with the bullshit completely discredited theory of Global Warming
Always a PARROT BAWK = I'm parroting the greater gurus
ISOSTASY: the equilibrium that exists between parts of the earth's crust, which behaves as if it consists of blocks floating on the underlying mantle, rising if material (such as an ice cap) is removed and sinking if material is deposited.
"Some 98% of Antarctica is covered by the Antarctic ice sheet, the world's largest ice sheet and also its largest reservoir of fresh water. Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level; subglacial lakes of liquid water also occur (e.g., Lake Vostok). Ice shelves and rises populate the ice sheet on the periphery. The present Antarctic ice sheet accounts for 90 percent of Earth's total ice volume and 70 percent of its fresh water. It houses enough water to raise global sea level by 200 ft."
