Larsen C, Almost Free

When last we looked, the Larsen C ice shelf was hanging on by an 8-mile sliver.

That's now down to 3 miles.

In the spirit of Layjez's calculation in the comments, that's 5 miles in about 36 days, or 1/7th of a mile per day. That's an average of only 0.2 meters per minute, compared to his (earlier) value of about 3 m/min.

So clearly this isn't linear, or easy to predict. The Antarctic is just coming out of its winter depth, which you'd think might have helped the crack to heal. But nature has other ideas.

At least this won't kill any penguins. That'd be a hell of a way to die.

My 7 year old son wants to claim the ice shelf once it breaks off. He says we could build a city on it. It's about the size of Rhode island but... I'm not sure he's though this one through.javascript:void(0)

He could put some sails on it and sail it up to Perth or the Persian Gulf or someplace dry like that, and sell the meltwater.

Looks like "Snowland" is free to be claimed: https://www.theguardian.com/world/2017/jul/12/giant-antarctic-iceberg-breaks-free-of-larsen-c-ice-shelf
