George Divoky's Planet
By DARCY FREY
1. IN WHICH GEORGE TRIES TO BUILD A FENCE
This is a story about global warming and a scientist named George Divoky, who studies a colony of Arctic seabirds on a remote barrier island off the northern coast of Alaska. I mention all this at the start because a reader might like to come to the point, and what could be more urgent than the very health and durability of this planet we call Earth? However, before George can pursue his inquiry into worldwide climate change; before he can puzzle out the connections between a bunch of penguinesque birds on a flat, snow-covered, icebound island and the escalating threat of droughts, floods and rising global temperatures, he must first mount a defense -- his only defense in this frozen, godforsaken place -- against the possibility of being consumed, down to the last toenail, by a polar bear while he sleeps. He must first build a fence.
Cooper Island, June 4, 2 o'clock in the morning. The sky is a cold slab of gray, the air temperature hovers in the upper 20's and the wind -- always the wind -- howls across hundreds of miles of sea ice with such unremitting force that George has disappeared beneath a hat, two hoods and a thick fleece face mask covering all but his bespectacled eyes. Standing near the three small dome tents that make up his field camp on Cooper, George raises a pair of binoculars and begins to scan for bears. Past the island's north beach, a wind-scarred plain of sea ice stretches uninterrupted to the pole. To the south, the nearest tree stands 200 miles away on the far side of the Brooks Range. Here, some 330 miles north of the Arctic Circle, with the sun making a constant parabolic journey around the sky, George surveys a view that replicates in all directions: the snow-covered island merges with the sea ice at its shores, the dazzling sheets of sea ice stretch to meet a pale gray dome of sky. Surrounded by a vast, undulating whiteness, he appears to be standing in the middle of the Arctic Ocean. He appears to be standing on the tops of cirrus clouds.
''So, . . . '' he says, and the rest of his words are carried off by the wind.
''What?''
''I said, so maybe we should put up the polar-bear fence before we get too fatigued!''
Heading fast toward fatigue, I tell him that's a fine idea indeed, and exactly how many polar bears does he figure might be out there on the ice? George, who spends each summer on Cooper Island, is cheerfully indifferent to its dangers and discomforts and reassuring to those who aren't. Discussing a recent incident in which some Inupiat Eskimos had to shoot a bear that wandered into their nearby whaling camp, I consider it bad news -- there are bears in the vicinity! -- while George thinks of it as good: yes, but now there's one less bear.
Still scanning the faint horizon line, George insists there's nothing to get worked up about. For the most part, bears stay several miles offshore, where they can gorge on ringed and bearded seals. If a bear were to come to this island, he points out, its massive 800-pound frame would stand out against the sky like an approaching blimp. Even if a bear were to wander into camp, he goes on, we are sufficiently armed with a shotgun, cans of compressed pepper spray (mace) and a flarelike device known as a screamer-banger. Nonetheless, George confirms that at least one big bear shows up on Cooper each summer, usually to scavenge the beach for dead, washed-up seals; and furthermore, that an encounter can be so unpleasant that you do have to figure the odds a little differently. ''I was out here once and injured the tendon in my knee,'' he says. ''I couldn't walk, I couldn't stay warm. I kept thinking, If it's true predators key in on the weak and the infirm. . . . '' He shrugs and gestures to the chilling evidence of predation right by our feet -- a caribou skull, several seal vertebrae, a scattering of gull's feathers and the sun-bleached skeleton of a clean-picked walrus. ''I guess it's safe to assume that most of our fellow Americans are south of us, sound asleep, a lot warmer than we are, and not preparing to put up a polar-bear fence.''
Cooper is one of six barrier islands stretching off the coast of Point Barrow, Alaska, where the United States -- along with continental North America -- comes to a chilly, desolate end. Three miles tip to tip, the island is nothing more than a snow-covered strip of sand and gravel frozen into the Arctic pack ice, its only vertical relief an odd cityscape of rusted 55-gallon drums and destroyed ammunition boxes left here by the United States Navy sometime after the Korean War. In 1972, George came out to Cooper as a young ornithologist and discovered a rare colony of black guillemots -- pigeon-size, stiff-legged seabirds -- nesting in the abandoned drums and boxes. And for many years he pursued a rather esoteric study of them -- mate selection, age of first breeding, ''the kind of thing that's of interest to about 20 ornithologists,'' he says now. Then, almost by accident, he discovered that his birds were picking up on another kind of frequency, and that if he watched and listened with great care, they could tell him about something no less consequential than the climatic fate of the earth.
In coming to the Alaskan Arctic year after year, George is following the logic of many other scientists -- that to understand Earth's mysterious and changing climate, you should go directly to its extremes. In the last two decades, scores of researchers have come to the nearby town of Barrow, hoping to learn why the Arctic is warming so significantly and how the changing polar climate may affect the planet as a whole -- if the Arctic sea ice were to one day disappear, it would cause drastic changes in the climate of the Northern Hemisphere. But while many scientists gather their data from remote sensing devices -- satellites, buoys, robotic airplanes -- or come to this frozen, inhospitable region on brief, well-equipped trips before returning to the comforts of the ''Lower Forty-Eight,'' George spends three months of each year sleeping in a small yellow dome tent, warming himself over a two-burner propane stove and crawling around on his hands and knees, up to his binoculars in guillemot scat. Thousands of miles away from the debates on greenhouse-gas emissions, relatively unknown even within the scientific community, George, now 55, has come out to Cooper Island every year for more than 25 years, often with no financial or institutional support. It is not too much to say that he has staked his entire adult life on this barren gravel bar and its avian inhabitants. And now, as he continues to scan the island with his binoculars under bright, 2 a.m. skies, it is not too much to say that his life is staked on whether he can successfully erect that polar-bear fence.
The fence became an essential part of George's repertory for survival after he awoke in his tent one night to the crunch, crunch, crunch of approaching footsteps. When he crawled out to investigate, however, he thought he must have been dreaming: he was alone on the island. The next morning, the 16-inch tracks in the snow told him otherwise. If it's possible to see your life flash before your eyes in retrospect, that's what happened to George: a big female bear and her cub had walked within 20 yards. While the cub stayed put, the mother came up to the doorway of his tent, evidently sniffing George's placid, sleeping head before he woke, unzipped his sleeping bag and inadvertently scared both bears away.
''All right, let's see what we've got here,'' George says, shaking the many parts of the fence out of its canvas bag onto the snow. George's fence is made up of 30 three-foot-high garden stakes that he and I, fueled by the adrenaline of our recent arrival, now try to place in a circle around our tents. Each stake has a small pulley, through which we thread a fine piece of cord. The cord makes a perimeter around the tents and meets up at the home stake, which is connected to a spring-loaded mousetrap, an eight-volt battery and a car alarm with a large plastic horn. The fence operates on the principle that a bear wandering into camp will push the cord, the cord will trigger the mousetrap, and the closing of the mousetrap will complete an electrical circuit that turns on the alarm, thereby waking George and me to the dangers at hand.
That, at any rate, is the principle. For more than an hour, we struggle to drive the garden stakes firmly into the snow, and each time we test the fence by pushing at the cord, a stake pulls loose and the cord slackens, preventing the triggering of the mousetrap. Then, when George turns his attention to the car-alarm horn, a sharp crack echoes in the air, followed by the gentle sound of his voice: ''Uh-oh. I think I broke it.''
Although George has spent more summers on Cooper Island than he often cares to count, he seems, upon first meeting, an unlikely candidate for the solitary hardships of fieldwork in the high Arctic. Handsome, boyish, with disheveled hair and a face deeply creased by abundant laughter in subfreezing temperatures, George lives nine months of the year in Seattle, and there is about him the unmistakable air of the overcaffeinated urban neurotic. He wakes up talking and, rushing to get the words out, keeps up a rapid, digressive chatter -- about George Bush and the Kyoto Protocols, the challenges of romantic commitment and the latest from Philip Roth -- almost until the moment, 18 hours later, that he falls directly asleep. It seems a waste of his conversational gifts for him to be on Cooper Island alone. It's also somewhat alarming. When I first met George in Barrow last February, I watched in wonder at his interactions with the mechanical world -- forgetting to keep his car engine running when the outside temperature dropped to 30 below; or, when he parked and did remember to plug his engine block into an electric heater, forgetting to unplug before driving off -- snap!
But for almost three decades, he has hurled himself to the very ends of the earth and met its risks and challenges with tireless enthusiasm. When his new stove broke on the first day of one field season, he kept a series of bonfires going all summer; when he ran out of freshwater, he placed tin cups around his tent to catch the rain; when his radio broke, he tried calling for help with an old signal mirror from World War II. (He also tried spelling HELP on the beach with large pieces of driftwood, but came up one log short, inadvertently announcing to the skies a pressing need for KELP.)
Now, holding the two halves of the car alarm in his hands, he shrugs and says, ''To be honest, the fence doesn't keep bears out; it just lets you know that one is about to eat you. Really, it's just a placebo.'' He looks around at our camp -- one tent for cooking and two for sleeping that we've pitched far enough apart for privacy while also keeping, in George's words, ''within screaming distance.'' For our campsite, he chose what seemed the safest, most sheltered location near the island's south shore -- out of harm's way, and back from the thick, upended slabs of sea ice that have rammed up against the island to the north. But as far as I can see, we are nothing if not in harm's way: like a Bedouin camp in the desert, our three yellow tents are the only signs of life in this white-on-white landscape -- the only signs of food, come to think of it, to an animal so wily that it stalks prey by sliding on its belly behind a moving block of ice and is said to raise its white paw to cover its black nose for camouflage in the snow. ''Any bear that shows up on this island is probably very hungry or very deranged,'' George says fatalistically, ''and there's not much you can do to keep Charles Manson out of the suburbs.''
