OMG, We're All a Gonna Freeze!

Sea ice in the Antarctic has been increasing at the rate of roughly one million square kilometers every two years:

If you extrapolate this over the globe, which has a surface area of roughly 510 million square kilometers, we can clearly see that the world will be covered with ice in a mere 1,000 or so years, a mere blink of an eye geologically.  Even if the arctic ice melts first, as hopeed predicted by Al Gore, the North Pole will become encased in ice from the south.  As Mark Twain himself wrote:

In the space of one hundred and seventy-six years the Lower Mississippi has shortened itself two hundred and forty-two miles. This is an average of a trifle over one mile and a third per year. Therefore, any calm person, who is not blind or idiotic, can see that in the Old Oolitic Silurian Period, just a million years ago next November, the Lower Mississippi River was upward of one million three hundred thousand miles long, and stuck out over the Gulf of Mexico like a fishing-rod. And by the same token any person can see that seven hundred and forty-two years from now the Lower Mississippi will be only a mile and three-quarters long, and Cairo and New Orleans will have joined their streets together, and be plodding comfortably along under a single mayor and a mutual board of aldermen. There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.
