Greenland may be 3,000 miles from Charleston, South Carolina, but what's happening there will determine the city's fate. 

Lauren Petracca and I connected the dots in a project we called "The Greenland Connection." 

The main story features an Elvis impersonator and a shaman, among other things, and delves into an issue the national media hasn't really addressed in depth -- Greenland's powerful gravitational effect on ocean tides.

Here's how it begins:



1. Gravity

So many things in Greenland are gigantic. Greenland is five times the size of California, and roughly 80 percent is covered with ice. Greenland’s ice sheet is a mile deep on average, but near the center of the country it rises 10,000 feet into the sky. Greenland’s ice sheet is so thick and heavy that it makes the Earth wobble a bit as it spins, like an unbalanced top. When the ice sheet meets the ocean, the ice sometimes cracks and falls with the force of atomic bombs. Even Greenland’s language, Greenlandic, has huge words — one is 153 letters long.

Greenland’s ice is melting in a big way, too. This summer, so much melted in one week that you could flood the entire state of South Carolina with 2 feet of water. The ice sheet normally melts in the summer, but it’s melting faster now than it has in 12,000 years.

All this melting ice raised sea levels across the globe, just as dropping ice cubes into a whisky drink eventually makes a mess. Except some ice cubes in Greenland can be half the size of Manhattan.

There’s more: The Greenland ice sheet is so massive that it generates its own gravity. It pulls the Atlantic Ocean toward it like someone tugging a blanket. South Carolina is at the other end of this blanket, which means that Greenland pulls water away from our coast, lowering our sea level. But as the ice melts, its gravity disperses and its grip loosens. Seas at the far end of the ice’s power slosh back.

That’s one reason sea levels in South Carolina have risen faster than many other places around the globe.

Greenland is 3,000 miles north of Charleston, but this distant land of ice, polar bears and reindeer already has reshaped our coastline. It has made Charleston’s tides higher, our flooding worse. And what happens in Greenland in the future will largely determine the Lowcountry’s fate.

These forces come with overwhelming numbers, so it’s best to start smaller. Perhaps by flying in a 78-year-old plane over the world’s fastest-moving glacier.

With an Elvis impersonator on board.

Cougars in South Carolina

Here is a story I did recently for The Post and Courier in Charleston, SC, raising the question: Are cougars still in South Carolina? The elusive Carolina cougar By Tony B artelme Sunday, January 29, 2006 Got one. A man is on the phone, and he's excited. "We have our cougar," he says, and he has proof. A photo. Come out and look. And so you speed up Interstate 26 faster than you should, and 45 minutes later you're in Bill Cook's yard near Cross, holding the picture. And there it is: A cougar slinking through the woods, about to pounce on a deer. Cook says he got the photo from a neighbor who got it from another neighbor who said the shot was taken behind his property. You think, maybe you're holding the first proof in a hundred years that cougars aren't extinct in South Carolina. Maybe. But the Internet is a useful tool, and later, when you plug the words "cougar deer" into Google, up pops the same darn photo on half a dozen Web s

One Brain at a Time - Chapter 1

Image
A man lies in a hospital deep in the Tanzanian bush, dying of a head wound. His only chance is if someone opens his skull and stops the bleeding, but the hospital doesn't have a bone-cutting saw. An American brain surgeon volunteering at the hospital has an idea: A villager next to the air strip is cutting a tree limb with a wire saw. That might do. He buys the wire saw for $15 and heads back to the operating room. Improvise. That's what you do when you're a doctor in one of the poorest countries on earth. This is the story of a brain surgeon from Charleston and his mission to teach Tanzanians his skills. A Doctor's Quest: Teaching brain surgery in the bush BY TONY BARTELME The Post and Courier Sunday, July 25, 2010 Open the skull, and look at the brain. It's beige with a slight tint of pink and shaped vaguely like the head of a cauliflower. Now touch it. That's what Dr. Dilan Ellegala asks his medical students t
