In July, when a massive iceberg broke off a shelf in Antarctica, we created a tool that tried to estimate how long it would take to drink all of the water the iceberg contained. We’ve repurposed that tool below, but must offer the caveat that you should not actually drink any (much less all) of the water that’s flooding Texas.

If you drank 20 80-ounce glasses a minute, it would take you 13.7 million years.

This is a volume equivalent to 7.4 percent of Lake Erie, after all — which you should also not drink, at least without filtering it somehow.

Lake Erie, incidentally, is about 571 feet above sea level, on average. If you started at sea level and created a one-mile square column of Harvey water, it would end up towering over 42,000 feet above your head.

We can do the same calculation from anywhere on Earth.

(That brown block, incidentally, is the size of a football field.)
