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
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.
