Natural Patterns

Part of this post appeared on the original blog under the name “A Natural Complexity” in 2012.

A new El Niño is beginning, apparently.

El Niño refers to an unusual weakening of the trade winds, which causes warming of certain parts of the Pacific ocean. The name means “the Child,” referring to the Christ Child, because of the bad fishing the warm water causes off of Peru around Christmas during El Niño years. The pattern radically changes the weather across much of the globe. For example, El Niños partially suppress Atlantic hurricane activity but increase hurricane formation in the Pacific. A stronger trade winds and a cooling of the Pacific is called La Niña (“the Girl,” because it is the opposite of “the Boy”) and likewise alters worldwide weather. The Pacific moves between these two extremes every three to seven years for reasons no one really knows. The cycle is called ENSO, for El Niño Southern Oscillation.

Earlier this month, NOAA (National Oceanic and Atmospheric Administration) announced that while the ENSO is currently still neutral, the Pacific is warming in ways that suggest an El Niñowill develop sometime this year. When it will develop or how severe it will be if it does, they cannot say yet. NOAA reassesses the ENSO every month, and they should be much more sure of their prediction in June.

ENSO extremes cause extreme weather of various types, so if an El Niño does develop, we can expect this coming winter to bring unseasonably warm weather to parts of Alaska and Canada and a lot of snow and rain to the Southeastern United States. Some Americans will therefore announce that global warming is definitely happening because of all the weird weather, others will announce that global warming can’t be happening because look at all this snow,  while still others will insist that it is just  El Niño, which has recurred for thousands of years and has nothing to do with greenhouse gases. Little sub-arguments will rage over whether and how global warming and the ENSO interact (nobody actually knows). The great debate will rage; is this weather natural?

And that is the wrong question.

The truth is that global weather patterns are extremely complicated and any particular weather event has many different causes, all operating together. Identifying what caused any particular hot day is a bit like attributing a wave in a crowded swimming pool to one particular swimming kid. The occasional cannon ball leap aside, the question cannot be answered. Scientists don’t try.

What scientists do instead is to look at probabilities. They look at the swimming pool and they measure the waves and they analyze the measurements with powerful computers. They ask “is this group of waves about what we would expect, given that a dozen kids are hopping up and down in the water?” If the answer is no, they don’t need to know which wave is natural and which wave isn’t; they know the pattern as a whole has changed and there is something new happening in the water.

When climate scientists announced that the heat waves and droughts of 2012 were definitely the result of global warming, they did not mean that natural weather has ended, or that we will never have an unseasonably cold spell again (we’ve have some since then).  What the scientists meant was that the pattern has changed. There is an extra kid in the pool, now. And every wave, big and small, will now be the combined result of all the original kids plus the new one.

This winter, we’re going to be swimming around next to a very bouncy kid, the Boy, El Niño.  He’s been in the pool a long time. He’s one of the older kids, though he isn’t always splashing around so much. But even though the Boy might be drawing attention to himself, each wave will still be the result of many causes all interacting together, and the new global warming kid will still be in the pool, making the entire pool different than it would be if he were not there.

The new kid in the old pool is us.

What Does “Unstoppable” Mean?

About three weeks ago now, researchers announced that the melting of a group of glaciers in Antarctica had become “unstoppable.” The water in those glaciers, once released, will raise sea levels by about three feet over the next few decades or centuries, drowning some low-lying coastal regions and islands and exposing many more to an increased risk of flooding from storm surges. The announcement made the news and now seems to have disappeared.

Aside from protesting this back-to-business attitude (did you all hear this? The shape of the continents as we know them is about to change!), I want to clear up some possible misconceptions.

First of all, the reason scientists are sounding the alarm about this one group of glaciers is that these are the glaciers they looked at. Antarctica is a very big place and research there is difficult, so there are a lot of glaciers they did not look at so closely but that might be melting also. Plus, there are other sources of meltwater (like the glaciers in Greenland) raising sea levels and as the oceans get warmer they expand, also raising sea level. So we’re not really looking at just three feet of rise over the next two hundred years, we’re talking about three feet from this one source, plus more feet from all of the other sources.

Second, not all of this melting is visible to a casual glance. Glaciers can and do melt by getting shorter; you can visit a place and say “OMG, that glacier used to fill this valley and now it stops all the way up there!” But they also get thinner. A glacier can lose a lot of mass and still cover the same area that way.  The only way to tell is to measure the changing elevation of the surface, which these scientists did using the ERS-1 satellite.

With these particular glaciers there is also another problem. Glaciers form on land and flow over land, but they do not automatically melt or break up on contact with the sea.  If the water is cold enough, they just keep going for a while, forming large floating shelves of ice. But these glaciers are so thick and heavy that they need very deep water in order to float. Until they get out to deep water, they keep flowing along the ground, even though the ground itself is below sea level. The place where a glacier finally separates from the ground and begins to float is called the grounding line and the location of the grounding line is another thing that can change dramatically without the glacier looking much different from a casual glance. If a glacier gets thinner it also gets lighter and needs less water to float. The grounding line retreats inland.

Where the grounding line is matters a lot, matters more, actually, than whether the ice actually melts.

The issue is that flouting ice does exactly the same thing to sea level that extra water does. You can demonstrate this yourself with a glass of water and some ice cubes. Drop the ice in the water and the water level rises–it may overflow the glass. But notice that if the water level is right at the top of the glass (as if it has just overflowed), the ice floating in the water actually sticks up above the top of the glass a little. So what happens if you let that ice melt, does the glass overflow again? No.

The space ice takes up in water is exactly the same as the space it will take up when it melts. Ice floats because water expands when it freezes (water is at its most dense just shy of 40°F or 4°C. Warm it or cool it from that point and it gets bigger) and the tip of the iceberg that sticks up out of the water is always the exact difference in volume between the ice and the same water in a liquid state.

What this means is that ice raises the sea level when it floats in the sea, whether it has melted already or not. So when scientists say that the grounding line of a glacier is moving inland by multiple kilometers a year, that is a very big deal.

Finally,there is the issue of what “unstoppable” means. Does it mean it is time to give up hope, that there is nothing we can do anymore? No, it does not.

First of all, glaciers flow, so how soon a glacier ends up in the sea depends not just on how quickly it melts but also on how free of obstruction its path is. So if the end of a glacier melts, the ice that was behind it can flow more freely and it heads toward the sea faster, unless there is a mountain ridge or something like that to get in the way. Part of what the scientists mean by “unstoppable” is that they don’t see any mountain ridges under these particular glaciers they are studying, so with the front of the glacier melting the ice now has an increasingly clear path to the sea.

But the other thing that they mean is that they honestly don’t believe we’re going to do what must be done to stop the melting; halt greenhouse gas emissions. As Eric Rignot, one of the researchers in question, wrote,

Two centuries – if that is what it takes – may seem like a long time, but there is no red button to stop this process. Reversing the climate system to what it was in the 1970s seems unlikely; we can barely get a grip on emissions that have tripled since the Kyoto protocol, which was designed to hit reduction targets. Slowing down climate warming remains a good idea, however – the Antarctic system will at least take longer to get to this point.

Now, that really doesn’t sound like he means that drastically cutting emissions wouldn’t stop the melting, only that a drastic reduction isn’t going to happen, in his view.

Let’s prove him wrong on that, shall we?

California Drying

I’ll follow up on the bad news about glaciers next week. In the mean time, here is an article on the drought in California that I originally published on the old blog site–since the drought is ongoing and has already spawned some awful wildfires, it seemed timely to revisit the issue. This article was originally published in February, 2014 and has since been edited for greater clarity.

For much of the United States, this winter has been all about cold and snow. But for the other half of the country, though, this winter has been about drought and heat. And it turns out, the two extremes are related.

California is entering its third consecutive year of deep drought. In 2013, California as a whole got less than a third of its average amount of precipitation. January is typically one of the area’s two wettest months, but as of mid-January, some areas had received only a trace of rain. Los Angeles had received no rain at all. This is the driest period on record for California. Tree ring studies suggest that this is the driest the region has been for nearly 500 years. Nevada and Oregon are also in very serious droughts, and parts of eight other states are also in a state of Federal emergency due to drought.

Much of the Western U.S. is also unusually warm. Parts of California topped 80 degrees in January, while parts of Alaska approached 60 degrees.  60 degrees in Alaska in January is not only bizarre but also dangerous, since the warmth has caused a massive avalanche that completely cut off the only road into the town of Valdez. Wherever it occurs, heat makes drought worse by increasing rates of evaporation.

At the beginning of February, the California Water Project, for the first time ever, announced it would not supply any more water until further notice. The move means that the state must now rely only on local water sources, such as wells, without access to regional reserves.

The current drought will probably break eventually, but this sort of thing could be the new normal. Current land and water use policy in the American West is based on the amount of water available in past years, but we now know that the recent past was an unusually wet period for the region. What looks like drought to us may simply be a return to normal. Over the past thousand years or so, this area has also experienced several “mega-droughts,” extra-dry periods lasting a hundred years or more.

If California is heading into a mega-drought, or even just returning to the historical normal, then there won’t be enough water for its people and industries, a shortage that will have national consequences. More wildfires means that California will have to draw on out of state resources more often, potentially depleting the country’s ability to fight fires in other regions. 15% of the food sold in the U.S. in grown in California, the loss of effective irrigation would raise food prices nation-wide.

Does this have anything to do with global warming? In a word, yes.

This winter’s wet cold in the east and the dry warmth in the west are related. A persistent blocking high—a huge bubble of high pressure—has sat over top of the northeast Pacific for months. As the name implies, the blocking high prevents storms carrying moisture from the Pacific from making it to shore. The bubble also diverts the jet stream northward, directing warm, tropical air straight up into the arctic and destabilizing the polar vortex. We’ve gotten used to “polar vortex” being used to mean a cold snap, but actually it refers to a ring of high wind around the poles that usually serves to keep the coldest polar air in place. When the polar vortex weakens, it leaks, spilling frigid air into unusual places, like Atlanta, Georgia. This blocking high has been in place for nearly a year now.

But this process—a weakening of the polar vortex because of melting sea ice—was predicted by climate scientists years ago. It’s exactly what they said would happen. So, yeah, this is what climate change looks like.

So, let’s DO something about it, please?

Water, Water Everwhere

It has been a strange week for weather.

A massive rainstorm has flooded historic Harper’s Ferry, West Virginia, not an unprecedented event, but still dramatic. At the same time, drought-struck California has begun what may be its worst wildfire season in recorded history. Perhaps even more disturbing, widespread flooding in the Balkans has caused multiple landslides, inundated whole villages, and the still-rising water now threatens Serbia’s most important power plant. At one point, a third of Bosnia was under water. The most frightening detail is that some of the flooded and destabilized areas were active mine fields left over from the Bosnian war, and now nobody knows for sure where those mines are.

Whether these floods and droughts would have happened without global warming is debatable; the Balkan floods especially are unusual, the worst in 120 years, since record-keeping in the region began, but unusual whether has always happened occasionally. As a general rule, of course, larger and more frequent flood events, with correspondingly drier periods in other places or between floods, are par for our course now in many parts of the world.

What is unambiguously a result of climate change is the recent bad news about the Antarctic.

There has been a lot of confusion about ice in Antarctica, in part because some of the ice there has actually been growing in recent years. But the part of the ice that really matters has been shrinking and the bad news is it’s shrinking twice as fast now as it was only a few years ago.

To clear up the confusion, the big distinction for Antarctic ice is between sea ice and glacial ice. Glaciers begin their existence as snow that falls on land. If more snow falls in the winter than can melt, the snow builds up and eventually is crushed into ice by its own weight. Because of that weight, glaciers flow gradually towards the sea, like giant frozen rivers. Glaciers store the snow of thousands of years. That is a lot of water. If a glacier melts or flows into the sea faster than new snow can replenish it, that water comes out of storage and the sea level rises.

In contrast, sea ice forms when the sea freezes. The extent of sea ice matters for all sorts of reasons, but sea level rise isn’t one of them. That is because floating ice takes up exactly the same amount of room in the water as the meltwater from the ice would. That is why you can make your drink overflow by dropping ice into it, but when you let the ice sit and melt the level of your drink does not change at all. Try it sometime. What matters for sea level is not whether water is liquid or solid but whether it is in the sea already or not.

Antarctica’s expanding sea ice does not negate global warming because, unlike the arctic sea ice, it mostly melts during the summer already. When we talk about the northern ice cap shrinking, we’re talking about its size over the summer. Summers are getting warm enough now, even in the arctic, to melt a lot of it. But most of Antarctica’s sea ice already melts away during the summer, so when we talk about its changing size we are talking about it in the winter, and Antarctica’s winters are nowhere near warm enough to melt ice. Its increasing sea ice probably has more to do with changing wind patterns and a less salty ocean (from all the glacial meltwater) than temperature per se.

Another possible source of confusion is that Antarctica has multiple distinct regions of glacial ice and one of its regions actually was growing more ice until recently. The most recent measurements show that region as stable, neither gaining nor shrinking. But most of Antarctica’s glaciers have been shrinking for a while now.

But the bottom line is that recent satellite data shows that the melting of some of Antarctica’s glaciers has sped up dramatically in recent years; the satellite can see the surface of the ice dropping in elevation. This is not a prediction or a model, it is observed data. Researchers are sure now that some of the glaciers of Western Antarctica are going to completely melt. The only major question is how long will they take to do it?

There is enough water in those glaciers to raise global sea level by four feet. All that melting could take two hundred years, but that’s hardly reason to ignore the threat, and of course there are a lot of other glaciers that could melt also, speeding up sea level rise.

The headlines from all of this are mostly that the melting is now “unstoppable,” which obviously implies quite a bit of doom and gloom. But the researchers themselves don’t say that now is the time to throw in the towel; now is the time to get busy. “Unstoppable” doesn’t mean exactly what it seems. I’ll get into more details on that later this week.

For now, the take home message is that there is no time to wait. The water is coming.

Counting

You know, sometimes I think the problem is that most of us just don’t count. No, no, no, I don’t mean we don’t count as in we don’t matter, I mean we don’t count as in we look at a number of objects or people and don’t bother to count them.

Like how so many people say “I’m just one person, what does it matter what I do?” Well, how many people is everyone else? Even big shots, political and economic leaders, are one person each. I don’t mean to deny that President Barack Obama has more power than you do, but he is powerful because other just-one-persons do what he tells them to do, not because he is more than one person. Everything that has ever been done by human beings has been done by people who were just one person each, just like you. “One” is the number of people humans come in, and it hasn’t stopped anybody else from making a difference.

Just as there are people apparently unaware that nobody is more than one person, there are also those unaware than none of us are less than one person. All exhortations that you should make a difference are based on the remarkable proposition that you have the option to not make a difference, even though all human beings do make a difference simply be existing. We eat and breathe and talk, we weigh something. Even if your contribution to the world is in no way unique (I’m not sure it’s possible to not be unique, but this is about math, not your self-esteem, and I’m trying to keep things simple), you do matter. Consider all the drops of water in a bucket; sure, each one is just a drop in the bucket, but together they weigh forty pounds, and there isn’t any drop in the bucket that does not add to that weight. Your weight is exactly the same whether you stay in the same bucket as everyone else, or jump to a new bucket with hardly any other drops in it. Whether your weight helps create the status quo or helps shatter it, you make a difference. You can’t avoid making a difference. All you can do is decide what difference you want to make.

These two mathematical mistakes, that some people are more than one and that some people are less than one, together breed apathy. You can tell yourself you don’t have to cut your petroleum use to zero, because you’re just one person so you don’t matter. You can also tell yourself that using a lot of petroleum for convenience and fun is ok, because everyone else is doing it. It doesn’t matter if you do it, too, because you’re one of many. By this logic, nobody is ever responsible for anything, because all of us are always either acting alone or acting with others. Who, then, is actually causing global climate change, the Not Me Ghost from “Family Circus?”

We are used to thinking of climate change as being nobody’s fault—or it’s the fault of politicians or business leaders, or your neighbor down the street who bought a gas-guzzler for no good reason. It’s true that when billions of people all work together to cause a problem, the actual percentage of fault for any one person should be vanishingly small, assuming that morality is subject to arithmetic. It’s also true that some people are more responsible than others. You could argue philosophical points along these lines until the world ends (and the great thing is you probably wouldn’t have to argue very long!) Or you can just say “it’s my fault, so I’m going to have to fix it.”

This is what Jim Merkel did in 1989, when the Exxon Valdez wrecked and spilled oil all over a previously pristine Alaskan coastline. Merkel writes movingly about this in his book, “Radical Simplicity;”

“As the reporters on screen combed the crew of the Exxon Valdez for the guilty, I looked across the polished bar at the mirror and knew it was me.”

Merkel was not an oil man per se. Although his petroleum use was on the high end in those days, as he traveled a lot for business, Jim Merkel was not claiming more responsibility than anyone else, he was just claiming responsibility. He had a sudden, profound awakening, utterly changed his lifestyle, and has devoted the rest of his life to helping others do the same. I recommend his book.

But I recommend following the intent, not the letter, of his advice. He suggests a form of energy diet, a variation of the sort of thing you can find on the Internet if you search for ways to calculate and reduce your ecological footprint. In theory, the idea is to count up how much of the Earth’s resources you use, and then reduce your use until you reach your fair share. In practice, however, measuring your whole footprint is complex to the point of impossible, so you have to make various assumptions and shortcuts, all of which can be debated until the end of the world.

Now, certainly any radical reduction is a good thing, so go ahead and use a foot-print-reduction plan if you want to. You’ll raise your own awareness and that of your friends and associates while you’re at it. But there is a simpler way; get off fossil fuel.

Fossil fuel is the heart of the problem, although land use, cement production, and other factors also contribute to climate change. Part of the issue is that cheap energy exacerbates all of these other problems (would anyone cut down the rainforest to graze cattle for export if shipping were slow and expensive?). The larger part of the problem, though, has to do with the global energy budget. Plants do most of our carbon sequestration and ultimately provide all of our fuel in one form or another (including both feed for draft animals and fossil fuel). There is a direct relationship between how much energy is stored in plant matter and how much carbon dioxide burning or eating those plants releases–because the plants stored the energy in carbon molecules in the first place. Burning fuel always releases carbon dioxide and always will, but if you used energy slowly enough that the plants could re-grow (a sound economic plan), you would be carbon-neutral by definition. This kind of sensible, nearly automatic thriftiness is almost impossible with fossil fuel, because the whole point of using fossil fuel is to get more energy than modern woodlots and farm fields can give us. That, by definition, means releasing more carbon dioxide than the plants of today can sequester. That causes global warming. Limiting ourselves to the energy available in the active, non-fossilized part of the biosphere (which includes solar, water, and wind, but not nuclear energy) will end human-caused global warming, provided we can learn to use our resources sustainably.

Of course, in our society, using fossil fuel is often logistically necessary, but that can be changed—by you. And me, and other people. There’s more than one of us involved. Once we start trying to live without fossil fuel, we can go about solving the problems that we encounter (building local food systems and alternative fuel transportation options, for example). When you run into a wall you can get busy building a ladder. Other people will then climb your ladder.

We’re counting on you.

Cowboys and Indians, Part 3

This is the final post in a three-part series on the Reject and Protect protest again the proposed Keystone XL pipeline in April. The first post described what it was like to be at one of the events of the protest, the second post explained who had staged the protest and why, and this one addresses the media response to this and other Keystone protests.

Part of the reason to stage a protest is always to get media attention for the cause. Rightly or wrongly, perceived public opinion has a big influence on how most of us see the world, and we infer public option largely through the public media. If a tree falls in the forest and doesn’t make the evening news, does anyone care? Maybe not. With that in mind, I was interested to see whether and how the news media covered the Reject and Protest pipeline protest a few weeks ago.

The short answer? Not badly, considering the event was relatively small (perhaps a thousand or so people on Saturday, the day I was there).

The main television news shows did not cover the event, at least not in my neck of the woods, nor did our local newspapers carry the story. It did not make the national headlines. Nevertheless, some impressive organizations, from Fox News to the Huffington Post and Al Jazeera, have at least mentioned the protest. News blogs associated with ABC and NBC covered the story briefly but fairly, and the event also received coverage through various activist sites and more openly editorial TV shows.

Notably missing in all of this is the PBS Newshour, which has not covered any of the Keystone protests this year, and there have been some major ones. Given their reputation for liberal sympathies (which may or may not be deserved),this is surprising. Could there be something unethical going on? It’s an important question to ask, but in this case the answer seems to be no.

PBS has indeed been accused of climate-denial sympathies in the past, typically for giving equal time to climate change deniers when they cover climate issues. Part of the problem is that David Koch has served on the boards of two member stations and is a major donor. These stations have given the appearance of pulling or altering programs in deference to the Kock brothers’ interests. The Kochs have made much of their fortune from the oil industry and are major funders of the Heartland Institute, a climate change denial organization. Michael Getler, the PBS Ombudsmen, has responded to these allegations at length, and says that there is no evidence that David Koch was involved in any of the relevant editorial decisions.

More importantly, Mr. Getler points out that PBS is a program distribution body only and makes no editorial decisions at all. Member stations are responsible for producing and acquiring programming. That means that while it is possible for a member station to succumb to a conflict of interest (though obviously they shouldn’t), PBS as a whole simply does not have the authority. That means that if the entity that actually produces the Newshour has no conflict of interest then a possible ethical problem exists elsewhere in the system is irrelevant.

As it turns out, PBS Newshour is not produced by any PBS member station, but rather by McNeal/Lehrer Productions, an entity that is in turn largely (but not wholly) owned by Liberty Media Corporation, which is a communications investment company, not an oil company. Could a conflict exist anyway? Yes, of course. Following money around is notoriously difficult and I have not dug very deeply. But lots of things are possible, that doesn’t mean there is any good reason to assert that they are. Let’s not get overly cynical at the expense of anyone’s good name.

In any case, the Newshour does, in fact, cover some climate-related stories very well and has discussed the Keystone pipeline several times over the years. They just haven’t been covering the protests. They cannot cover all possible issues, because of space limitations. The different between them and the commercial news agencies may simply be that the Newshour covers its stories at much more depth and therefor does not have the time to do as many of them. PBS does not necessarily place a lower priority on the protests than its competitors do.

It is possible that mainstream journalists are honestly confused about how to handle climate-related issues. Their training as journalists may predispose them to respect anyone who asserts an opinion on anything. They might not be prepared to identify the difference between the Union of Concerned Scientists and the Heartland Institute.

So, obviously, we need to do more outreach in order to teach journalists and other public figures that climate change is of critical importance. And, in the meantime, the protests may simply have to engage in more spectacle in order to get attention. Like, for example, they could try having cowboys and Indians in feather headdresses set up tipis on the National Mall and ride horses through Washington DC.

Oh, wait; they just did that.

Breaking Barriers

Cowboys and Indians 3 will post on Monday. In the meantime, here is a re-post from the original blog on the Climate Emergency Institute site.

Global climate change may be too abstract a notion for many people to think clearly about. Information, like pizza, cannot be chewed or digested well if you bite off too big a piece at once. Anything that prevents large numbers of people from thinking clearly and concretely about a problem can effectively block public change.

In the interests of moving through this block, I contacted Bill Hulslander, Chief of Resource Management at Assateague Island National Seashore, and asked him about sea level rise. Using his responses, plus my own familiarity with the island as a former intern there, let us look at climate change in one, particular place.

Assateague Island is part of the barrier island chain protecting much of the Atlantic and Gulf coasts. These islands and peninsulas are essentially very large offshore sand bars with forests, shrub-lands, and marshes growing on them. They protect the mainland from the worst of ocean storms and provide valuable wildlife habitat, unless they are converted to resort towns, as most of them have been.

Assateague is one of the few exceptions. It is not one park but three, with different parts of the island managed by different agencies. Famous for its free-roaming horses, Assateague also supports several endangered or threatened plants and animals. The island is 37 miles long, and varies in width from about two miles on the southern end to a few hundred yards in the north. It straddles the border between Maryland and Virginia. As a low-lying island, Assateague is vulnerable to changes in both sea level and the frequency and intensity of storms. As a tourist destination familiar to millions of people, it is a place where people might see change they can relate to.

Not all change on Assateague is related to sea level rise, and not all sea level rise is related to climate change. For example, the land in this part of the country is subsiding for geologic reasons, so the sea would be gaining on the island anyway. Also, Assateague is made of sand and sand moves easily. Storm waves would constantly reshape the island no matter what.

Mr. Hulslander says that the sea has been rising globally since at least the 1800’s (he does not say whether that rise is due to global warming, but it certainly could be, given that the Industrial Revolution had already begun). That means it is impossible to say what the island would do, how it would move, without sea level rise. There is no baseline data. All this means that it is hard to tell which of Assateague’s changes are natural and which are not. It may be enough to know that Assateague is changing, and that climate change is one of the reasons why.

Assateague moves west as major storms wash sand over the island and into the bay behind it. The process erodes the beach while building up the marshes on the other side of the island. Most visitors don’t notice this movement, because it has not changed the overall character of the land in recent years. Park rangers do notice it. They have had to move or abandon some of their infrastructure on the island. They can easily remember old, historic buildings lost to storms, their former locations now permanently under water.

The rangers tell the story of a man whose family did not sell their land on Assateague to the government when the park was created. He returned years later, curious about his property. The rangers gently explained to him that his land (which he had been paying county taxes on) was now several yards off shore. The rangers helped him sort out his tax problem, and the story is usually told in a light-hearted way, but one can imagine this family’s disappointment and regret.

The Park Service is working to plan for the coming changes to the island’s shape and size, so that their land is not unexpectedly discovered under water, too. As part of this effort, park scientists are carefully mapping the island and studying its relationship to the sea. Again, according to Mr. Hulslander:

A sea-level rise of 3.5 to 9 inches (8 to 22 cm) by 2040 may claim some of the barrier island’s valuable landscape.…The pace of sea-level rise will be the determining factor in the ability of habitats to adapt to new landscapes and environmental conditions.  If the pace is too swift, [and the growth of the marshes cannot keep up] the island may reach a tipping point and become more of a broken chain of low, sandy islands.

The loss of an intact barrier could make the mainland behind more vulnerable to storms, as well as being psychologically difficult for those who love Assateague. Whether or not the island breaks up, many of the natural communities on Assateague may be altered or destroyed due to periodic flooding and changes in groundwater salinity. In the short term, says Mr. Hulslander, some endangered species may find habitat on the island enhanced. Both seabeach amaranth and piping plovers, for example, need the sand flats created when storm waves wash over the island. Higher sea levels, plus an increase in the severity and number of storms caused by warming seas, means that waves will wash across the island more often. More frequent overwash means more habitat for amaranth and plovers, up to a point. Other species with different needs may not fare as well, and storms that are too frequent will wash even the sand-flat dwellers away.

Once upon a time, the loss of individual barrier islands would only have displaced natural coastal communities to other islands, or to the newly exposed mainland. Change is typical for barrier islands, and the number and location of barrier islands has varied historically. Unfortunately, the guiding rationale for the creation of parks is that by dedicating some land to wildlife and nature-based recreation, a portion of these resources will be protected in perpetuity. Meanwhile, surrounding lands are converted to farmland or beach-font resorts, because the need to preserve wild lands has supposedly been taken care of.

The very rapid change Assateague is beginning to undergo is at odds with its designation as anything in perpetuity. The island cannot serve as a refuge if it is flooded.

The Park Service as a whole is making plans based on multiple possible climate change scenarios for the next few decades. These scenarios are based on the various plausible emission rates. The research that will allow the park to develop specific scenarios for its own island has only begun. As Mr. Hulslander points out, these are planning tools, not predictions. If the island does X, the rangers are prepared to do Y. Some, or all, of the infrastructure on the island may be moved to the mainland. Some camping may also be moved to the mainland.

It is sobering to consider that nearby islands, such as Fenwick, are subject to the same pressures from sea level rise and increased storms. Ocean City, Maryland, which sits on Fenwick Island, can hardly be moved to the mainland. The city is fighting the sea by piling the beach with extra sand, for however long they can keep up that expense. The people who live on that island are vulnerable.

It is sobering, too, to consider that Assateague Island National Seashore is only about fifty years old. It is possible that, barring a miracle of public willingness to deal with global warming, some of the people who saw it win Federal protection may live to see the island break.

Cowboys and Indians, Part 2

This is the second of a three-part series on the recent Keystone Pipeline protest in Washington DC.
So, who were the people we joined in DC last week, to march once again against Keystone?

Individually, the people I referred to in my last post are as follows:

  • The two MCs were Dallas Goldtooth, of the Lower Sioux, and Jane Kleeb, of Bold Nebraska.
  • The water ceremony was lead by Casey Camp, of the Ponka Nation. I did not see the ceremony itself, but she did speak to the crowd as well. She was a slim, middle-aged woman of great dignity.
  • Greg Grey Cloud, of the Rosebud Sioux Tribe, lead the 4 Directions song, which was actually the 6 directions song.
  • John Ellwood, of Bold Nebraska and Pray No XL, was the Protestant preacher.
  • Wizipan Little Elk, of the Rosebud Sioux Tribe, Meghan Hammond and Diana Steskal, of Bold Nebraska, and Eriel Deranger, of the Athabasca Chipewyan First Nation, all spoke.
  • Steve Tamayo, of the Sicangu Lakota described the art on the tipi (I’ll explain that shortly)
  • Chief Reuben George, of the Tsleil-Waututh Nation offered a final prayer
  • Gitz Crazyboy, of the Dene and Blackfoot Nations, offered a closing prayer and next steps
  • The final performer, whom I did not stay to see, was Frank Waln, of the Rosebud Sioux Tribe.

The march as a whole was just part of a larger event called Reject and Protect. The leaders of the project call themselves the Cowboy Indian Alliance, and describe themselves as “a group of ranchers, farmers, and tribal communities from along the Keystone XL pipeline route.” That means not only people whose properties are crossed by the route but also, in some cases, people who are downstream of the proposed route or who depend on the aquifer underneath the route. The proposed path for the pipeline has changed over the years; some CIA members initially got involved to protest the pipeline being near them only to have the route moved onto their property as a result of other people’s concerns.

Bold Nebraska,  loosely speaking, the cowboys of the Cowboy Indian Alliance, is an organization of ranchers and farmers concerned with making the political process more diverse and participatory, but Reject and Protect is a major part of theirs. It was not clear to me whether the various Indians of the Alliance were there representing their communities–that is, has the Ponka Nation taken a position against the pipeline in the same way that Bold Nebraska has? The question may or may not even be culturally relevant.

Reject and Protect itself actually lasted from April 22 to April 27. The march was just one activity of this larger encampment of tipis on the National Mall. Other activities included multiple prayer services and ceremonies, presentations of documentaries, meetings with various officials, other demonstrations (there was one at Senator John Kerry’s home on the 25th), songs and stories, and the decoration of a tipi for President Obama.

This last was no snarky protest but a genuine and generous gift. The canvas tipi cover served as a backdrop for the talks and performances on Saturday, galloping with horses and the hand prints of many people, among other symbols. It is a true work of art, designed by Steve Tamayo and carried out by him and by many other people. He explained some of its symbolism, but he never explained exactly why giving this gift is supposed to sway Obama’s mind. Perhaps the idea is simply to say “we are here, we are people, and you cannot ignore us.”

The march I participated in was the delivery of the tipi cover to the Smithsonian Museum of the American Indian, which had agreed to accept on behalf of Barack Obama.

As I said last week, climate change per se was hardly mentioned by any of the organization leaders, though many of the marchers carried signs and shouted slogans that referred to climate, and of course an oil pipeline has everything to do with climate change. One way to look at this intersection of climate and other issues is the way I chose last week; by supporting these people in their fight for clean water,we can also fight for the climate as a whole. But there is another way to see exactly that same connection.

The climate issues that affect all of us means threatened drinking water to some. Polar bears make fine and accurate poster-children for the dangers of climate change, but they are a little remote for most of us to really make a priority of. Athabaskan children watching their parents die of bile duct cancer, which is super-rare except among people who live near tar sands extraction–that brings it home a bit more. And, unlike polar bears, the cowboys and Indians are perfectly capable of calling B.S. on feel-good green-washing that does not actually solve their problem.

One of the chants the organizers brought to the march was a simple call and response; they shouted “climate!” we shouted “justice!”

As long as fossil fuel remains the dominant energy source of the globe, somebody is going to be in the way of extraction, transport, and processing: Appalachian communities devastated by mountain-top removal mining; people able to light their tap water on fire because of fracking; killer smogs caused by coal smoke; or land and water poisoned by oil spills from trains, pipelines, tanker ships, or well-heads. If the stuff does not travel by pipeline through Nebraska, it will travel by rail-car across the tributaries of the Chesapeake Bay.

Unless it does not travel at all.

My favorite of all the signs I spotted on the march was a simple red octagon on a stick reading “STOP the GLOP.” Because that’s really what this comes down to. Every kilowatt hour generated by fossil fuel, every gallon of gas, every piece of plastic, means GLOP in somebody’s life. Climate change itself–extreme weather, sea level rise, acidifying oceans–is also a form of glopping up lives, generally the lives of the poor and disenfranchised. The fossil fuel industry and the various government bodies involved in regulating that industry may be sincere in their willingness to minimize the damage, to route pipelines and other oil infrastructures through the least vulnerable places available, the fewest people’s lives possible, but those few people who are directly affected have a right to object to being treated as collateral damage.

Of course, rare to vanishing is the choice that does not make somebody’s lives harder. Shutting down the fossil fuel industry, for example, would destroy a lot of livelihoods, leave unemployed a lot of people who cannot afford it. Part of the job of government is to make decisions about who gets the short end of the stick because, in almost all cases, somebody has to for the greater good.

The question is, is perpetuating the fossil fuel industry really for the greater good?

Is fossil fuel and all it has wrought really worth continuing to glop up somebody’s life? If not, then rather than trying to reroute the pipeline or try to get the cowboys and Indians to simmer down, or arguing that transporting oil by train is worse (which may be true but is beside the point), perhaps our energy is better spent in stopping the glop and figuring out something better to do instead?

All You Need Is Love

This is a repost of an article I published about two years ago. I’m repeating it now because it is thematically related to the Keystone protests. The next post in the Keystone series will come out next week, either Tuesday or Thursday–there are some current events in development that may require their own article.

Last May two of my grad-school buddies and I were spending way too much time in the library. With too much to write before the end of the semester and not enough time, we had each parked ourselves in front of our favorite computer on campus, and by chance all three computers were in a row. I think it was the third or fourth day that we started getting punchy. Tyler mimicked birds. Brent started “eep”ing. I got the giggles. In retrospect, I suppose it was inevitable the Beatles would become involved.

“All together now!” sang Brent.

“All together now!” I responded, to make sure he knew I got the reference.

“All together now!” he replied.

“All together now!” I continued.

“ALL TOGETHER NOW!”

We repeated this, at intervals, for something like a week and a half. We were trying to cope with the monotony of theses and term papers and internship paperwork that just wouldn’t get finished. We were also, I think, trying to nail down an in-joke, bank the fires of circumstantial friendship against the ending of that circumstance, just days away. This is grad school, and finishing up papers can take years, but classes were over. We’ve scattered now already. I see them on Facebook occasionally.

We are, or will soon be, masters of science, two conservation biologists and a resource manager, respectively, assuming we all get jobs. It would be nice to think of ourselves as girding on the sword-belts of scientific expertise to fight the demons of biodiversity loss and climate change with the Green Ray of Knowledge. That was certainly our intent when we started this, or at least it was mine.

But climate change really isn’t a scientific problem anymore. Oh, sure, there’s details to sort out; how fast, how bad and where, there’s a lot we don’t know—enough to keep thousands of researchers busy forever, if not exactly paid. But we know the basics; carbon dioxide, methane, nitrous oxide, and several other gases trap heat in the atmosphere, and we are producing these gases in large quantities, making the Earth warmer. All kinds of problems are ensuing as a result. We’ve known that for decades, and the obvious solution has not really been tried, not on a large scale. How much more do we need to know?

No, climate change is a political problem. The collective will isn’t there. Maybe it’s complacency, maybe it’s fear of change, maybe it’s that certain industries have more dollars than sense and can dominate political discourse. Maybe it’s Blue Meanies.

I’ve just finished watching “The Yellow Submarine,” the cartoon Beatles vehicle I’m young enough to have grown up watching. The film opens in the paradise of Pepperland, where the people sing all day, until the attack of the Blue Meanies who turn everyone grey. Occasionally, one of the grey people cries, or notices a butterfly and smiles, only to be bonked by a Bonker-Meanie. A child holds a brightly-colored pinwheel until a Meanie notices and eats the toy in passing. At last, the Beatles arrive and sing, the people become colorful again, and revolt, singing All You Need is Love.

Silly, yes, but how come the people turned grey to begin with? Why did they stop singing when the Meanies attacked, if song makes Meanies go away? All too often, this is what people do; a huge number of people act against their own interest because the Blue Meanies told them to do it, and the Beatles haven’t shown up yet.

But sometimes people don’t wait. They sing and laugh and get bonked for it. Sometimes they win. Sometimes they don’t. Either way, they become the change they want to see in the world.

The Transition movement, for example, consists of towns and cities acting on their own to get off fossil fuel, prepare for Peak Oil, and prepare for the effects of climate change. Steve Chase, a co-founder of Transition Keene, in Keene, argues that the local work of the Transition movement, in addition to being worthwhile for its own sake, could also spark national and international change. To support his argument, he cites the Civil Rights movement, which Steve grew up watching, and which fought for recognition sometimes “one lunch counter at a time” before ultimately winning Federal legal support.

Steve acknowledges that Transition differs from the Civil Rights movement in its organizing model. The American Civil Rights movement was what Ghandi called the resistance program. Although the movement was non-violent, it was also aggressive, a deliberate attempt to stop other people from doing things they wanted to do (murdering with impunity, for example). Non-violent protest and civil disobedience were attempts to stop a moving wheel by calmly, gently, even lovingly, thrusting a stick between its spokes.

The International Transition movement is instead doing what Ghandi called the constructive program; creating the community structures of the new world without waiting for the structures of the old world to go away.

In an unpublished article on the Transition movement, Steve Chase acknowledges that this may not be enough. The Transition movement is, as yet, too small and too young to attract official attention, but eventually Transition Towns will likely be sued, legally reined in, or otherwise threatened. In this country, we are unlikely to be physically attacked, but fear can be effective whether or not the threat is real. Even simple discouragement can make the people go grey.

But we know that can happen. We can prepare. Let’s make up our minds that when the Blue Meanies come, we won’t wait for the Beatles.

All together now.
