No. We needed to go back to the plan to pump water out from under the big glaciers, to drop them back on rock beds to slow them down. Slawek had been right all along. It was the only thing that was going to work. We had been following the money, taking it where we could get it and doing what they asked us to do with it. The billionaires and oil companies and Russia even the NSF had said, Pump seawater back onto Antarctica, cool idea! Do it! But we were the glaciologists, so we had to guide the process if it was going to have any chance of success. Give expert advice, guide the money where it needed to go.
So, the next Antarctic season we were back. We went every year anyway, of course, but for once this was a really good reason to go. Mostly we just like it down there and are looking for excuses. Science! Is the ice on Antarctica five million years old or fifty million years old, huge argument! That kind of thing. Pure science. This was much more applied. It felt good.
This time we went to the Pine Island Glacier above the WAIS, the West Antarctic Ice Sheet. Pine was running narrow and fast into the sea, right next to Pine Island. It had been a study site for many years, so NSF had the logistics in place for getting a camp installed there.
Although in fact they weren’t experienced in getting as much stuff there as we needed. We needed almost as much as McMurdo itself, not really, but NSF had decided that if we were going to give this idea another test we had better make it a good test, or we wouldn’t know what our results meant. Our first try long ago was now worthless as data, because no one had ever followed up on it to find out why that hole had cut off and gone dry.
So we borrowed the ships that resupplied McMurdo at the end of every summer, and a couple of Russian icebreakers, us having been so stupid as to neglect icebreakers for decades and then build only a couple of wimpy ones, really suitable only for the Arctic, where there’s practically no ice left anyway. But the Russians love icebreakers, and they sent a couple of their monstrous beasts south to help us bash an open-water lane to Pine Island, where we could land stuff and drag it over and up onto the glacier, using the same snow tractors that had been dragging fuel and gear from Mactown to Pole for many years. Without too much in the way of fuck-ups we were established on the Pine Island Glacier outlet about a month after Winfly had opened Mactown for the season. A very impressive logistical effort.
This was my twenty-fifth visit to the Ice, and while on Pine Island I was going to break the six-year mark for living on glaciers, which was not the craziest of icehead records, but respectable. My wife has never been happy about this, but I like glaciers. And here I was again, out on Pine Island, which is really just a bump in the ice, entirely submerged by it, white sastrugi to the horizon in all directions. It has to be admitted that all Antarctic glaciers look much the same. The Dry Valleys are fantastic, but 98 percent of the continent is not like them. It’s ice on ice, for as far as the eye can see.
So, we deployed the equipment to our first borehole site and got to work. It was like dragging a village over the ice, some kind of Baba Yaga thing, the monster tractors pulling trains of four or five huts in a row behind them from spot to spot. We started between the Hudson Mountains and Pine Island itself; this was a perfect pinch point in the glacier’s fall, a place where if we could thump it back down on its bedrock, it would slow for sure. So we circled the wagons and got to work.
It’s cold in Antarctica, yeah. You forget that back in your university office in Louisiana or Pennsylvania or California or Ohio, or wherever you winter over. Even when your home in the world feels colder than Antarctica, like in Boston, you still forget that the Antarctic cold is really a true, deep cold, so cold it burns. Then after a few days in it you forget about it again. Of course a wind will remind you, and you don’t want to go out poorly dressed, or get frostnipped or even frostburned, or get to the point where if you flick your cold ear it breaks off and falls to the ground, but for the most part, it’s just the way it is. Cold. Keep a good selection of gloves and deploy them as appropriate. Humans evolved in ice ages, and properly dressed are good in the cold. Just deal.
So, the ice borers were still as simple as showerheads. Slow but effective. In the old days we burned a lot of fuel to get the showerhead’s water hot. Now solar panels helped to power the heaters. The meltwater under the showerheads gets suctioned and pumped out of the hole and reheated and used again, with the excess piped a distance away to freeze somewhere else. To both sides of the Pine Island Glacier are regions of ice moving slowly, so the water could be dumped there. In truth it was such a small volume that where we dumped it didn’t matter. We could have let it go into the ocean, it wouldn’t even have registered there. We could almost have drunk it as our drinking water.
We also began to make use of the microwave energy beamed down to us from the Russian satellites in their almost-polar orbits, to power the pumps and the showerheads when the sun went down. Test whether we could make that work, so we could keep the system going year round.
That first experiment had at least taught us this, that you probably wanted to choose a homogenous block of ice within the flow of the glacier, so that the movement of the glacier wouldn’t deform the hole as we drilled it. We had chosen our site partly for that reason— it was a single block that was forty kilometers long and extended all the way across the glacier. Still 130 kilometers upstream from the ice shelf, and a couple hundred meters above sea level. Perfect.
We had done the calculations as to how many drill holes we needed, and how far apart they should be and so on. It was pretty audacious; suck enough water from the underside of the glacier for the whole block of ice that we were working on to lose its water cushion and crash back down onto bedrock, hopefully with a mighty squeal and maybe a crashing sound, as of tires braking on asphalt followed by car hitting wall. Even if that only happened in our heads, it did seem like it was going to be palpable when it happened.
Slawek’s numbers were holding good. Amount of water lubricating the bottoms of Antarctica’s glaciers roughly sixty cubic kilometers. Not insignificant, a clear cube of ice about four kilometers on a side and the same high, so, half as tall as Everest— yes, a lot of water for humans to pump. But not outside the zone of what we already pump every year.
Still, a lot of water to pump, but that’s for all of Antarctica. Around the circle of the continent, about fifty glaciers dump the majority of the ice now rushing into the sea, with a few being the major contributors. Starting from McMurdo and running clockwise, you need to stick the Skelton, the Mulock, the Beardmore, the Carlyon, the Byrd, the Nimrod, the Lennox, the Ramsey, the Shackleton, the Liv, the Axel-Heiberg, the Amundsen, the Scott, the Leverett, the Reedy, the Horlick Ice Stream, the Van der Veen Ice Stream, the Whillans Ice Stream, the Kamb Ice Stream, the Bindschadler Ice Stream, the MacAyeal Ice Stream, the Echelmeyer Ice Stream, the Hammond Glacier, the Boyd, the Land, the Hull, the deVicq, the Murphy, the Haynes, the Thwaites, and our Pine Island; then around the Peninsula to the Drewry, Evans, Rutford, Institute, Möller, and Foundation ice streams; then the Support Force Glacier, the Blackwall Ice Stream, the Recovery Glacier, the Slessor Glacier, the Bailey Ice Stream, the Stancomb-Wills Glacier, the Vestraumen Glacier, the Jutulstraumen, the Entuziasty, the Borchgrivinkesen, the Shirase, the Rayner, the Beaver, the Wilma, the Robert, the Philippi, the Helen, the Roscoe, the Denman, the other Scott, the Underwood, the Adams, the Vanderford, the Totten (biggest of them all), the Dibble, the Francois, the Mertz, the Ninnis, the Rennick, the Tucker, the Mariner, the Priestly, the Reeves, the David, the Mawson, and the Mackay.
That’s actually seventy-four. So, sixty cubic kilometers sucked out from under seventy-four glaciers. Okay, not so bad!
Especially compared to 3,600 cubic kilometers, right?
So we were melting and casing twenty boreholes into Pine Island Glacier. After that we’d pump up all the water that we could. It didn’t seem so bad! In the same realm as wells up in the world, draining fossil water for farms all over the Ogdalilla and other places set atop irreplace
able groundwater resources. Can be done! Solves all problems!
All right, it doesn’t solve all problems. But let’s not get picky. If sea level rises even a meter, all the beaches in the world are gone, and seaports and coastal infrastructures and salt marshes and you name it. And as Hansen and his team pointed out in their 2016 paper, if the rate of rise doubles every ten years, quickly you are fucked, all the coastal cities of the world devastated, damage in the quadrillions, if you think you can put a price on it. What’s the monetary value of human civilization? Trying to answer that question proves you are a moral and practical idiot. Well, economists make such calculations all the time, but that’s their job, and they think it makes sense. In this case, better just to throw up your hands and say civilization is effectively a fiscal infinity, a human infinity.
Tacking down the Antarctic glaciers won’t completely stop sea level rise, of course. But if we could get the big ones back to one-tenth of their current speed, like the good old days, that would help a lot. Best to do it in Greenland too— the ice there is going even faster, and even though it has only a tenth the ice of Antarctica, that’s still a seven-meter sea level rise, if all of it were to liquify. So fine, do them too; Greenland is easier, it’s basically a stone bathtub with narrow cracks in it. Tack down those suckers falling through the cracks, and you’ve got a somewhat stabilized sea level, rising at about a millimeter a year— meaning a thousand years before it rises a meter. Enough time to draw down enough CO2 to get back to 350 parts per million— hell, enough time to start another ice age if you want to!
Basically, the sea level rise problem gets solved. Beaches still in existence.
So, someone asked tonight in the mess tent, is what we’re doing down here geoengineering? Who the hell knows! What’s in a word? Call it Glacier Elevation Operations, Based on Estimates of Godawfulness Gobsmacking Interested Nations’ Goodness: GEO-BEGGING. Call it whatever you want, but don’t immediately clutch your pearls and declare we can’t predict the unintended consequences, we are sure to create backlash effects so bad they overthrow the good we intended, etc. There are some things man was not meant to know— my ass! We are meant to know everything we can find out. So get over that whole wimpy line of objection. And I’ll tell you what the unintended side effects of slowing down the glaciers of Antarctica will be: nothing. Nada. No side effects whatsoever, and the beaches and coastal cities of the world will stay out of the drink.
So if this works, and it looks like it will, I think we’ll be doing it. Our team is relatively small. The project is expensive but not that expensive. Like drilling a few wells anywhere else, pumping water anywhere else, plus keeping everything warm. And getting the stuff and people here in the first place. That will be expensive, yes, and dangerous, but a quick calculation of the cost of this operation of ours multiplied by something like a hundred, or even a thousand— that gets us to ten billion dollars. Well, probably it will be more expensive than that, everything is when you actually get into it. But whatever— call it fifty billion dollars. This is such a bargain!
So, I’ve been waking up every morning excited to get out there. Actually this is always true for me in Antarctica. Jamesways, mobile homes, tents, Mactown; get up and try to stay warm through breakfast and prep, gear up, out the door and bang— freezing sunny cold air, like a wallop of vodka and a slap to the face. Eyes streaming from the double whammy. Give a hoot and head to the line of snowmobiles. Get one of them started, off on the track leading to whichever hole I’m working on. The snowmobile roads are flagged, and the flags tell me what the wind is up to that day. If it’s windy then it’s going to be cold, that’s the law in Antarctica. That’s why they’re always saying, it’s not the cold, it’s the wind! Although when it’s windless, it’s still cold. But with a wind you are going to freeze your butt. The wind just ransacks you, no clothing is enough. You’d have to be in a spacesuit to be shut of it, and even then you’d be cold.
Today I made the rounds and found that every hole was working. Pumps pumping, heating elements keeping the water liquid. The lines from each pump feed into a bigger pipeline, like a piece of the Alaska pipeline lying right on the ice, with repeater heaters every kilometer, and joints where you can get into the line and run a pig if you need to melt an ice clog. The pipeline is running slightly uphill, which I think is an interesting decision, as you could actually just let it run downhill into the ocean, the addition to sea level rise would be so trivial, well below detection level. But people like to be neat.
It’s a funny place to describe, Antarctica. You can’t really get it across to people, what it looks like and what it feels like. I think the clean dry air makes for some optical illusions that add to the feeling that things don’t look quite real. Often it’s just snow and sky. That is very common. A sky clean of clouds. Around the coast there are clouds sometimes, more often than on the polar plateau, but still: blue sky, white snow under it. Sometimes smooth snow, sometimes sastrugi. Sastrugi and even completely flat snow look different when you’re looking toward the sun and when you’re looking away from it. When looking toward it, there’s a glare off icy snow, a blaze off snowy snow. Then when looking away from it, the white goes somehow dark— which is a strange thing, maybe due to the polarization of your sunglasses, but very noticeable when you turn around and look sunward again. The contrasts are more than the eye can deal with. If there are clouds, like the fleets of low marine puffballs that float above the ice near the coast, then their shadows on the snow appear black; a flat snow expanse can suddenly look hilly or peppered with black mesas. More contrast than the mind can handle, now why is this beautiful? I can’t say. Maybe a lot of people wouldn’t say it is. But I like it.
Looks like tomorrow we’ll be able to run the final tests and declare the job done. Then in about a year we should be able to tell how it’s working in terms of slowing this beast down. Maybe five years to be safe. Although people will be in a hurry to declare one way or other. But if you’re going to be putting billions into it, and training a bunch of crews, you’d do better to be sure. Actually, one of the choke points in the supply chain, in terms of getting this done, if they decide to do it, is simply people. It takes a certain expertise. On the other hand if we’re shutting down all the oil operations, as we really ought to do, then that’s a lot of people out of work. And the work in question isn’t that different. Some of them might even regard this job as easier. Simple stuff, although colder. But if you’re working in Saudi Arabia, maybe you like the idea of cold. And if you’re working in Alaska, maybe it makes no difference. Yeah, that part will probably work out. We’ve only got fifty people here now, and you could do it with thirty— almost half of us are here to study the other half, or do science while we have the camp here, in the usual way. Again, scale that up and the number of people is still trivial.
We’ll have a party tomorrow to celebrate.
I’m sorry to report that this is the last entry in this file of Dr. Griffen’s laptop. He took a last inspection run on February 6, and on the way back to camp he took a shortcut that left the snowmobile road, which is clearly flagged. Visibility was good, so no one is sure why he did that. Usually he stuck to the flagged road, just like the rest of us. It’s normal practice on glaciers, where crevasses can be covered with old snow and completely invisible. And taking the shortcut wouldn’t have saved him much time anyway. So we are all mystified.
We were in the dining hut waiting for him, and when about an hour had passed, our mountaineers got worried and went out to check. Another thing we do is usually travel in twos. But Dr. G wasn’t always meticulous about that, and since the entire work space of the project was within sight of camp, none of us were. I mean you’d go to check on a pump or whatever by yourself, and to your tent by yourself, to the bathroom and so on. Just normal.
So when the mountaineers couldn’t find him in a quick tour of the wells, we sent one crew up the pipeline to see if he had gone to check the spillway and had a snowmobile problem. The re
st of us made the circuit looking for snowmobile tracks leaving our road system. It was all we could think to do, since we could literally see the whole surface of the glacier, and no sign of him. That in itself was deeply worrying.
It was Jeff, one of our mountaineers, who followed a snowmobile track to an unobtrusive hole. He then came back and got Lance, the team’s other mountaineer, looking grim. They went out to near it and then stuck in some ice belays and roped up, and walked over to look in the hole. We watched from the dining hut, standing around silently. Lance belayed Jeff, who descended into the hole. He disappeared and was gone about, I don’t know, twenty minutes. It seemed longer. Finally he reappeared and climbed out and stood there, then walked back to Lance. They conferred; Lance put out an arm and held him by the shoulder. They hugged. They looked our way, saw us. Jeff shook his head. We understood it as clearly as if he had said it: Dr. G was dead.
That was a bad night. We sat around the dining hall, stunned. Jeff sat by the stove looking grim and distant. Of course when he got back to us we asked him what had happened, but he could only say what was obvious. Dr. G had driven off course, his snowmobile had dropped into a hidden crevasse. He went on to say the snowmobile was stuck about twenty feet down, and Dr. G’s body under it. Jeff didn’t say what condition the body was in. He didn’t want to inflict that on us, I guess, or didn’t want to compromise Dr. G’s privacy, I don’t know. Sophie and Karen were crying, and we all cried from time to time. Dr. G had given most of us our jobs, and several of us our educations, our careers. He was one of the old iceheads, the ones who keep coming back, the true Antarcticans. Jeff didn’t cry, nor did Lance. Lance was concerned about Jeff, he didn’t care about Dr. G. Beakers were always doing stupid things and getting killed, that’s why every team in Antarctica is required to have mountaineers as part of the group, to keep them safe. But you can’t lead them around on leashes, and if they break protocol you can’t stop them, even if you insist on protocol at the start of every deployment, go through the drill with the utmost seriousness, which truthfully many mountaineers are not good at mustering. So Jeff and Lance were grim, but not because they felt responsible. They were going to have to go down in that crevasse the next day and get Dr. G’s body into a bag, and haul him up to the surface, and get the body on a sled and back to camp. A plane from Mactown would be in tomorrow, if the weather allowed. They already knew about it there; their voices sounded shocked, sympathetic, the usual.
