The Taj Mahal Lie: Why Donald Trump Isn’t Our Problem

If you ask a random person on the street “who built the Taj Mahal,” I suspect you’ll get either of two interestingly wrong answers.

  1. Donald Trump
  2. Some prince in India

Different buildings, of course. The one in India is my concern at the moment, though we’ll get back to Mr. Trump later. Whenever I’ve heard the original Taj Mahal brought up in casual contexts (as seems to happen about once a decade, for whatever reason), the description has been something like “the Taj Mahal is a beautiful building complex built by an Indian prince for his beloved.”

Really? He built the whole thing himself?

The standard description is more or less accurate. According the the website of The History Channel, in 1632, the Muhgul emperor, Shah Jahan, ordered the design and construction of a mausoleum to honor his favorite wife, Arjumand Banu Begum, who had died in childbirth (on her 14th child). She was known as Mumtaz Mahal, or “The Chosen One of the Palace,” so her tomb complex was named the Taj Mahal. The remains of both her and Shah Jahan rest at the site, although he had intended to have a separate, equally magnificent complex built for himself. He was deposed by one of their sons before he could have it built.

Of course, everybody knows that the Shah did not literally build the Taj Mahal himself (the labor required over 2000 humans and roughly 1000 elephants and took 20 years). It is an easy guess he didn’t design it himself, either. Sometimes you do hear more accurate verbs in the story, like “commissioned,” or “had built.” It’s not like the truth is being hidden in any way, here. But the convention of speaking as if people who give orders accomplish things all by themselves–as if everyone else involved were simply an extension of the Great One’s body–is so ingrained that we seldom notice we’re doing it.

Who, for example, built the first mass-produced car? Henry Ford did.

Who defeated the army of Robert E Lee? Ulysses S Grant did.

Who burnt Atlanta during the Civil War? William Tecumseh Sherman did.

These answers are such common knowledge that I’m not bothering to cite any of them with links–you know they’re all true. Who were the other people involved in any of these endeavors and what were their contributions? I have no idea. And I doubt you have any idea, either. We don’t know because we don’t care–it is the action of the real person, the one who gave the orders, that matters.

All this is not simply semantic play. Proper attribution of who does what matters. Consider the statement “Hitler killed six million Jews.” It’s true as far as it goes, I’m not trying to say that people who give orders are less responsible, though focusing on the Fuhrer does tend to let thousands of co-conspirators and trigger-men off the hook in the popular imagination. But the phrasing consistently inspires people to fantasize about killing Hitler, as if doing so would avert all those other murders. And the fact of matter is, since Hitler didn’t kill those people alone, it is very possible that, without him, those others would have gone on to have the Holocaust anyway.

And this is where President Trump comes back in the story, not because he’s being compared to Hitler (he has been, but so has virtually every other public figure with at least one naysayer), but because he’s being compared to Richard Nixon.

Mr. Nixon was, of course the one US president who was most unequivocally a crook. He was crude, paranoid, and corrupt. But he also created the EPA and signed more landmark environmental legislation than almost anybody else.

Unlike our other stand-out environmentalist presidents, Teddy Roosevelt and Barack Obama, President Nixon was not an environmentalist personally. Aside from some largely empty rhetoric, he provided no real leadership on the subject, and in some cases he actively threw up roadblocks. He thought tree-huggers were stupid at best.

But the anti-environment campaign had not yet begun, so signing those laws carried no political cost. A lot of the young people who were angry about the Vietnam War also cared about trees and whales, and so forth. The President threw them a couple of bones so he could get back to matters that really mattered. And those “bones” have formed the backbone of environmental protection for the past 50 years.

So much of the Anti-Trump sentiment I hear sounds a bit like the kill-Hitler fantasies in that they rest on the assumption that Mr Trump personally is the problem. As though, were he removed (impeachment, resignation, tragic accident), all the problems and threats associated with his presidency would be removed. And they wouldn’t be. Because we already know what a crude, paranoid, and crooked man does when installed in the presidency and confronted with a functional environmental movement–he creates the Environmental Protection Agency, he doesn’t muzzle it. He enables environmental regulations, he doesn’t undermine it. Richard Nixon didn’t care any more about the planet than Donald Trump does, but he acted like he did because the public made him do it.

I’m not saying that the individuality of leaders is irrelevant. There are occasions when the course of history turns on a single person, for good or for ill. Arguably, Adolph Hitler was such a person. So was Abraham Lincoln. So might Donald Trump be, though it’s too early to tell.

But leaders do what they do because others help him, or because others force them, or because others let them. They never act, nor fail to act, alone.

Donald Trump is part of a movement, both of popular sentiment and of political machinations. I don’t mean he’s popular, I mean that he isn’t alone. He is being helped, forced, or at least allowed to do as he is doing. And that help, force, or permission will continue even if he’s removed. It will continue until it meets a countervailing force.

Why do we keep hearing that Americans, when polled, support environmental protections, including climate action, by a solid majority, yet we keep watching ant-environmentalists and climate deniers taking office? If we forced Mr. Nixon to do the right thing on these issues, why can’t we force anyone else?

Why does the opposition continue to virtually ignore environmental issues and why has it been so ineffective on the topics that it does care about?

Donald Trump could not have become a bother to anyone other than his immediate circle without a lot of help–and an absence of true, effective opposition. Whether the Trump presidency lasts eight years or one year, that is the problem we have to solve.

The Story of Global Cooling

I’ve been hearing climate deniers talking about a global cooling scare in the nineteen seventies for a while now, and I finally got curious about where this narrative had come from–I didn’t think it had been made up whole cloth, but I hadn’t heard word one about it from any credible source, either. You’d think that if climate scientists had thought an ice age was imminent as recently as the seventies, at least some of the scientists I know would mention it occasionally?

So, I looked into it. And I found not one but two explanations.

In one story, Peter Gwynne, a science writer for Newsweek, wrote a short article on an idea some scientists were kicking around at the time–that a thirty-year cooling trend might continue and develop into a real ice age. The article was published on April 28, 1975, and attracted enough attention that other publications picked up the story with their own articles. Books and TV shows followed.

Scientific American, my source for this particular story, explains that the cooling trend is

now believed to be a consequence of soot and aerosols that offered a partial shield to the earth as well as the gradual retreat of an abnormally warm interlude.

And that

there also was a small but growing counter-theory that carbon dioxide and other pollutants accompanying the Industrial Age were creating a warming belt in the atmosphere, and by about 1980 it was clear that the earth’s average temperature was headed upward.

Scientific American acknowledges that the global cooling thing has no legitimate place in the climate discussion today, and reports that Mr. Gwynne himself is somewhat embarrassed by the anti-scientific uses to which his writing is being put. He does stand by what he wrote, given the limits of available knowledge at the time.

Ok, but there are a couple of problems with that story, starting with the fact that the greenhouse effect was not a “small but growing counter-theory” in the 1970’s–the effect of carbon dioxide on the climate has been known since 1859. The first calculations of the human role in climate change were made in 1896.

And it’s not like global warming was some far-out thing nobody was paying attention to back in the 1970’s, either. No less a person than the fiction writer, Ursula K. LeGuin had started making oblique references to climate change as early as 1969 (her novel, The Left Hand of Darkness, includes a flawless description of the natural greenhouse effect, as well as a reference to an alien planet that is hot because “an exploitive civilization wrecked its natural balances, burned up the forests for kindling, as it were.” Several of her later books also refer to the Earth itself getting warmer, too). Perhaps more starkly, the 1970’s were when Exxon was busy figuring out what it was going to do about global warming, of which its internal documents prove it was well aware.

Beyond all that, there wasn’t a 30-year cooling trend, except perhaps in a mathematical sense. According to the National Oceanic and Atmospheric Administration (NOAA), the period from the mid-1940’s to the mid-1970’s was cooler than previous years had been, but there was a lot of minor temperature fluctuation, not a consistent cooling. A cool period of relative stability is not the same thing as an oncoming ice age.

So, I did some more poking and found the second story.

Apparently, in the 1970’s, the greenhouse effect was well-known, but the cooling effect of sulfate emissions (“aerosols”) had just been discovered and it wasn’t clear yet which would prove dominant. A few climate scientists thought the aerosols might win out–between 1965 and 1979, 10% of the scientific papers on the subject predicted cooling, but 28% could make no prediction and 62% predicted warming. In other words, the coming ice age was a legitimate scientific idea for a while, but only a small minority of studies ever supported it.

I’m not actually sure, based on what I’ve read, whether anybody ever proved that sulfate emissions couldn’t have counteracted carbon emissions under some scenarios that were plausible back then. As history has actually played out, sulfate emissions have been dramatically reduced (they also cause acid rain), while carbon emissions have continued to climb. Aerosols still complicate climate predictions, but no one thinks they’re going to cause an ice age anymore.

There’s no cooling trend mentioned in there.

The way I see these two stories blending, I suspect that what really happened was that the end of the warming trend of the first third of the 20th century was taken (maybe correctly) as evidence of the cooling power of aerosols. Some climate scientists thought the aerosols could go on to trigger a cooling trend, but most did not. Peter Gwynne, being a writer who cared about science and about getting his writing published, chose to focus on the minority opinion, since that seemed more sensational at the time. He has admitted that the story “pushed the envelope a little bit,” in deference to Newsweek’s penchant for what Scientific American called an “over-ventilated style.”

The ventilation would have seemed harmless at the time, if the article was fundamentally accurate, as I’m willing to buy that it was. Nobody can represent the entire breadth of the scientific conversation on any one topic in just nine paragraphs. You have to choose which of all possible stories you’re going to tell, in order to tell any story at all.

That deniers have since pounced on his article for political and anti-scientific purposes is not Mr. Gwynne’s doing. Being co-opted is a risk all published writers run–it’s the Scylla to the charybdis of being utterly ignored.

Curiously, the one detail I thought would enter the discussion apparently didn’t, except as a note of context written long after the fact by one or another of my sources–astronomically speaking, we’re supposed to be in an ice age already.

The primary factor that dictated the glacial/interglacial cycle through recent geological history was the Milankovitch Cycle, an interaction between three separate variations in Earth’s orbit that together dramatically how much solar radiation we get at different times of the year. We’re at a point in the cycle where we should be heading into a new ice age, but aren’t because our carbon dioxide levels are too high.

The connection between that cycle and climate was confirmed in 1976, so it may be another thread of the “global cooling” story that none of my sources happened to tease out–but if not, there may have been good reason to ignore it.

The onset of ice ages is very slow. I have to cite one of my grad school classes here (Tom Wessels was the teacher–I’ve cited him as a source here before) as I haven’t been able to lay my hands on an appropriate link, but ice ages melt quickly (as in many hundreds of years) and grow slowly (as in many thousands of years). In fact, the warmest point of our current interglacial (before now, anyway) was thousands of years ago. No, the cooling was never enough to initiate continental glaciation on North America or Asia, but cooling was in progress.There is an excellent illustration of this cooling, and how long and consistent it was, here (yes, that is a web comic, but this one’s not a joke).

Sliding towards an ice age doesn’t look like anything special, it turns out. More or less, it looks like all of human history.

Groundhog Day!

It’s Groundhog Day, the day when, supposedly, a groundhog in Pennsylvania predicts the weather by seeing or not seeing his shadow. It’s the closest we have to a climate-related holiday.

It’s an odd holiday–never mind how a groundhog could predict the weather, how can one groundhog give a single prediction for the entire country? And why six weeks? We can explore these questions briefly and then I’ll get back to talking about climate.

Groundhog Day itself goes back to Europe, where a group of interrelated traditions had various animals–hedgehogs, bears, badgers, perhaps even snakes–breaking hibernation in February to predict the remaining length of winter. The underlying idea is that clear weather in early February is, counter-intuitively, a sign of a late spring. And that association may well hold, at least in parts of Europe, for all I know.

February 1st or 2nd is also a cross-quarter day, one of the four days per year mid-way between a solstice and an equinox (the solstices and equinoxes are the quarters). The other three are May 1st, August 1st, and November 1st. All four were holidays in at least some of the pre-Christian European religions and all four survive as folk traditions and Christian holidays. All four are also holidays within the modern religion of Wicca. So today or yesterday is not just Groundhog Day but also Candlemas, Brigid, or Imbolg, depending on your persuasion, and all involve the beginning of spring. I have always heard that in European pagan tradition, the seasons begin on the cross-quarters, not the quarters–thus, spring begins not on the Spring Equinox but on the previous cross-quarter, in February. I’ve always wondered if perhaps “six more weeks of winter” is a remnant of cultural indecision as to which calendar was correct–whether spring should begin in February or six weeks later, in March.

In any case, we in America got Groundhog’s Day when German immigrants in Pennsylvania adapted their tradition to the New World–Germans looked to hedgehogs as prognosticators, but hedgehogs don’t live in America (porcupines are entirely unrelated). Groundhogs do. In the late 1800’s, the community of Punxsutawny announced that THEIR groundhog, named Phil, was the one and only official groundhog for everybody, thus utterly divorcing the tradition from any concern with local weather. There are rival Groundhog’s Day ceremonies, but Phil is still the primary one.

Groundhogs (which are the same thing as woodchucks) do sometimes take breaks from hibernation, though they don’t necessarily leave their burrows. There are various theories as to why, but most involve the need to perform various bodily processes that hibernation precludes–including, perhaps, sleep. Hibernation is not the same as sleep, after all. But there is evidence that male groundhogs spend some of their time off in late winter defending their territories and visiting females. They actually mate after hibernation ends for the year, but apparently female groundhogs don’t like strangers. Thus, it is actually appropriate that Phil is male–the groundhogs who come out of their holes in February are.

Anyway, underneath the silliness at Gobbler’s Knob in Punxsutawny, Groundhog’s Day is about a cultural awareness of weather patterns and animal behavior. Certain times of the year are cold and other times are not, dependably. If we pay attention, we can know what to expect and we can organize holidays and cultural observances around that knowing. In this sense, then, Groundhog’s Day is not about weather but about climate. Climate is the roughly stable pattern that makes it possible for ordinary people who don’t have supercomputers or satellites to predict the weather simply by watching the world around them.

We’re losing that, now. It’s fifty degrees outside, where I live. In February. And while warm, springlike weather is pleasant and I intend to go out in it as soon as I’m done writing this, there’s always something unnerving about unseasonable conditions. Yes, we’re under the influence of El Niño, a complicating factor. I’ve discussed the relationship of El Niño to global warming before, but that’s not the point here. The point is that the patterns our cultural traditions are build on–climate–are eroding. The world is getting less reliable, less like home.

It’s a little thing, as consequences from climate go, but one likely to have a profound effect on us psychologically. There is still time to do something about it. Get involved politically, support climate-sane candidates.

Now.

Looking Back

It’s time for our New Year retrospective again–here is a summary of the climate-related stories that caught my attention in 2015. I do not claim that this is an exhaustive or representative list. It’s in no particular order.

Looking over this list, I feel no particular optimism, but that doesn’t mean there isn’t any. I have a cold at the moment, which might make it difficult to remain up-beat.

Extreme Weather

The American Northeast became ridiculously snowy (although not unusually cold). California’s drought continued, as did drought in places like Texas and, for part of the summer, the Eastern states of the US. All of those places except California have also seen catastrophic flooding. Wildfires swept the Northwest of the US, from Oregon to Alaska and in to Western Canada. Several firefighters died. The planet as a whole set another heat record, and many new local heat records were set as well—few if any cold records. We saw some insanely powerful hurricanes and typhoons as well, all in the Pacific. Some of this wild weather is clearly due to our being in an El Nino, but climate change may play a role as well. It’s not either/or.

Fossil Fuels

The public process by which new offshore areas, including parts of the East Coast, could be opened to oil exploration has begun.

After years of largely symbolic political maneuvering, President Obama finally said No to the Keystone Pipeline.

A number of oil trains crashed. Same as last year. I hate that those two statements go together.

Shell Oil pulled out of its attempt to drill for oil off the coast of Alaska—which looks like a victory, but it is likely to ramp up pressure to be allowed to drill in the Arctic National Wildlife Refuge instead.

Electoral Politics

The US Presidential campaign is now well underway. And while the Democratic candidates at least are all climate-sane, the media has not been treating that aspect of their campaigns as important. I’ve been covering this issue because we have to win this next election, “we” being the climate sane, and the Democrats look like the vehicle to do it. This blog is neutral on all other issues.

ExxonMobile

We have learned that the energy giant knew about global warming decades ago, despite its more recent denialist rhetoric. Given that I knew about global warming decades ago, too, and I was a child whose father simply read a lot, I don’t see how this is a surprise. Still, there have been called to prosecute the company for fraud and I support those calls.

Paris Accord

The world’s leaders got together and decided that destroying the world would be a bad idea. Ahead of the summit, we in the US organized a series of demonstrations in support of a strong climate agreement and nobody noticed. I sound cynical and facetious. Actually, I am cautiously optimistic about the Paris climate accord. I am only cynical, at present, about the American political process necessary for meaningful action on the subject.

The Pope’s Letter

Pope Francis released an official open letter to his Church (called an encyclical) quite correctly describing climate change as a serious problem with a moral dimension.

Jellyfish Blooms

For the second year in a row, large numbers of jellies were seen in Maine waters, suggesting a deep ecological imbalance that is possibly climate-related—except nobody knows for sure, because we have no baseline data on jellyfish populations.

Syrian Refugees

Syria has blown up in all sorts of horrible, awful ways, from a massive refugee crisis to the formation of a really scary international terrorist organization that likes to behead men and sell girls as sex slaves in the name of God. And yes, climate could have played a role. These stories go back before this year, but it was in 2015 that they became dominant in American news (finally).

Your Tuesday Update on Wednesday: For a Little Boy

I first posted “A Family Expecting” shortly after the birth of my nephew. I have re-posted it occasionally since then, but he’s getting old enough now that I figured the piece was due for  a major re-write. So, here it is, edited for length and clarity, and with a new ending. Please check out the original for the research links posted at the bottom.

Yesterday, my first nephew was born. He is small and wrinkled and has acne on his nose. He has wispy black hair and silvery-blue eyes. He knows the voices of his family and the scents and sounds of the hospital. He does not know about his home, going to school, or getting a job. He doesn’t know about casual friends, mean people, or birthday cake. He doesn’t know what the world will be like for him.

Neither do we, obviously, but if he lives to see his 89th birthday then his life will touch the end of the century, spanning the same period of time across which many climate models dare to predict. He comes from farming people in the Peidmont of the Mid-Atlantic. If he stays here and inherits his parents’ farm, as he might, then his life will also be the life of this landscape. What will he see?

This child will go home soon, and become the son of the land. He’ll rest in a cradle on the floor of a barn, his mother rocking him with one bare foot as she directs customers picking up vegetables in June. In two or three years, he’ll carry handfuls of squash guts as gifts for the chickens and a rooster as tall as he is will look him in the eye and decide he’s ok. He’ll listen to his parents worry about droughts. He’ll learn to hope the heavy rains don’t rot the tomatoes and that rising gas prices don’t break the bank. There will likely be more such worries as he gets older. Summers will be hotter. His mother will say it didn’t used to be like this, but grown-ups always say that.

According to the IPCC, by the time he’s a teenager, temperatures in the Mid-Atlantic will average maybe two degrees higher than they did during his mother’s childhood. That does not sound like much, but averages rarely do. One degree can turn a pretty snow into a destructive ice storm.

Warming, in and of itself, will be good for the crops; only a local rise of about five degrees Fahrenheit or more hurts productivity. That’s unlikely to happen here until my nephew is a very old man. But the Great Plains may warm faster, enough to cause a problem; he could study the shifting agricultural economics in college. Or, he might prefer the shifting flights of birds, since many migrants head south based on conditions in Canada, and Canada will warm faster yet. Should be interesting.

Our area could either get wetter or drier. Parts of northern and central Mexico will almost certainly get drier, maybe dramatically so. These areas are dry already, so I imagine a lot more people will start heading north. My nephew will discuss the refugee problem with his friends, lean on his shovel in the morning sun, and wonder if the United States has a responsibility to keep Mexicans from dying when Congress is already deadlocked over how to pay for the flooding in New England. Seems you can’t keep a bridge built in Vermont, anymore. He takes off his sun hat and scratches his thinning hair.

Years pass. My nephew thinks about his upcoming fiftieth, and also about New York City, where three of his grandparents grew up. It’s turning into a ghetto. It’s not under water, exactly, though the highest tides creep slowly across abandoned parking lots in some neighborhoods, spilling over the older seawalls. The problem is this is the second time it’s been stricken by a hurricane, and now no one can get the insurance money to rebuild. The same thing has happened to New Orleans and Miami. Boston may be next. Those who can get out, do. Those who can’t, riot. They have a right to be angry. His daughter is pregnant with his first grandchild. My nephew cannot keep his family safe indefinitely, but he’s glad his parents taught him how to grow food.

My nephew turns sixty-five. He proud of his skill as a farmer, especially with the way the rules keep changing. The farm seems to be in Zone 8, these days. He’s got new crops and new weeds. He’s got friends in southern Maryland who haven’t had a hard frost in two years. Maybe this year they will; Farmer’s Almanac says it’ll be cold. Last year he and his wife took a trip through New England and let his kids take care of the harvest for once. They stayed at romantic little bed-and-breakfasts and took long walks in the woods, holding hands. There was white, papery birch-bark on the ground, here and there, the stuff takes a long time to rot, but he knew he’d have to go to Canada if he wanted to see one alive. It’s sad.

My nephew lives long enough to see more change than any prior human generation has, and that’s saying something. A lot of the change is environmental, but not all of it. Major technological shifts rework the country yet again, and the entire political and economic center of gravity pulls away from the coasts. He is aware of this upheaval intellectually, but viscerally he is used to the world he lives in. He lives well. He is loved and he is useful. No dramatic disasters befall him, the worst-case scenarios do not play out, but plenty of disasters do happen to other people. My nephew is sympathetic. He writes his Congress-people and gives generously through his church whenever he can.

But a lot of good that could have been done decades ago wasn’t.

I saw my nephew tonight. He’s at home now, wrapped in a blue blanket like an animate dumpling, slowly fretting against the swaddling. His wrists and ankles are as thin as my thumbs. He’s too young for baby fat. He doesn’t know what his future holds. And neither, really, do we.

——————–

I wrote the above fantasy several years ago and many of my predictions have already come true. My little nephew has indeed learned about birthday cake (I hope he does not yet know about mean people) and does indeed share his farm with chickens, though he prefers the company of the goats and can imitate their voices. More darkly, Manhattan was hit by a major storm-surge (Superstorm Sandy) and Miami Beach now floods regularly due to sea-level rise. I don’t think he knows it, but the years of his  life thus far have seen consecutive global heat records broken, two successive record-breaking tropical cyclones (Haiyan and Patricia), rumors of “jellyfish seas,” a major climate-related refugee crisis, the possible California Megadrought, and dramatic, unprecedented fires in Canada, the United States, and Indonesia. Among other deeply worrying developments.

Come on, people, put your backs into it, whatever we make of the future, my nephew will have to live there.

Your Tuesday Update: Prosecute ExxonMobile

As some of you will have heard, Exxon knew that climate change was real and largely caused by fossil fuel use back in the eighties. The company then publicly denied climate change for decades, working through many of the same PR experts who had previously worked for the tobacco industry.

In a way, this should not be news. After all, I knew about climate change in the eighties. And I was a little kid at the time, not one of the leaders of a major corporation. Of course Exxon’s leadership knew.

But for Exxon to use climate research to plot corporate strategy (such as deciding to pursue drilling in the Arctic because the warmer climate would make doing so cheaper) while simultaneously insisting to the public that these same studies were unreliable…it’s just insulting, is what it is.

And, as it turns out, the whole strategy may be illegal under the RICO statutes–the Racketeer Influenced and Corrupt Organizations Act, a law originally passed in order to tackle organized crime. The tobacco industry was successfully sued under RICO for exactly the same strategy of willful disinformation–so why not EXXON? The settlement could be big enough to fund some serious climate adaptation and mitigation and could discourage other professional deniers. This could be big.

I don’t suggest specific actions very often, but this seems important; please click here to sign a petition asking President Obama to sue ExxonMobile under RICO for climate denial.

Syria

The Syrian refugee crisis is starting to get scary. I mean, obviously the Syrian refugees themselves have been terrified for a long time, that’s why they have become refugees, but what I mean is that this is not a run-of-the-mill humanitarian disaster. This one has the potential to change the world, but not in a good way. The people are running from violence, primarily, and also poverty. For four years, now, people have been coming out–more than four million already. Mostly they go to neighboring countries, but many–more than three hundred and fifty thousand this year so far alone–make their way into Europe. Some are now being sent on to the United States.

To put this in perspective, Syria’s total population is now less than 24 million people, meaning that about one in every seven people in that country has recently left. Forced migrations on this scale leave scars that last for generations and radically change the cultures that take in the migrants–I’m thinking here of the Irish Potato Famine, which killed a million people and displaced a million, far fewer than in the Syrian crisis, but then Ireland was a much smaller country at the time. The whole world was much smaller. Almost two hundred years later, the Irish Diaspora continues to enrich the rest of the world–and the great-grand children of Irish refugees continue to take their history personally. I do, anyway.

The fact that I’m talking about Syria here suggests that climate change is involved somehow–and indeed it might be. The connection is that from 2006 to 2011, parts of Syria were in a very serious drought. Huge numbers of farmers were forced off their land and into the cities looking for work. The Syrian government severely mishandled the crisis, triggering the present civil war. The drought, of course, is just one more event made more likely by climate change. No less an entity that the US Defense Department warns that climate change is a destabilizing influence, capable of creating exactly the sort of mess currently exploding in the Middle East and into Europe.

The climate-deniers have, of course, cried foul, questioning the science of the drought attribution point by point. It is a mistake to argue science with those whose real objection is cultural or ideological, so I’m not going to offer a detailed rebuttal–but the point is not a direct causal chain, anyway. The point is that large areas of the Middle East and Africa are extremely poor, huge numbers of people living just above the poverty line–if anything goes wrong, they fall off into the abyss. Climate change simply makes it more likely for things to go wrong.

For rich countries, like the United States or most of Europe, a serious natural disaster (and we’re having two at present, the California drought and the related western fires) hurts us but does not destabilize us. We have enough of a safety margin that we can not only continue to take care of our own, we can simultaneously offer aid to other countries and take in refugees.

The reason the Syrian crisis is scary is that its scale hints at the possibility of a world where we will no longer be able to do that, where even if the United States remains comparatively rich, the number of things going wrong will rise so high that we will no longer be able to take our stability as a country for granted. Fourteen years ago today, many Americans made the unsettling discovery that we are not immune from attack. I did not–I never thought that our country was special in that way. It’s true we don’t get attacked very often, but that’s not because we live in a protective bubble. It’s not because we’re immune. But I gotta say, I’ve gotten kind of used to this national stability thing.

For weather to contribute to a civil war is nothing new. Weather and climate have always been one of the drivers of history–as James Burke elegantly demonstrated almost twenty years ago. Where crops fail and where they succeed, where floods and fires occur and where they do not, even something as simple as where the weather is pleasant, all these things have always been one of the several facets of historical events. The only thing that has changed is that weather, that thing that has always shaped events, is becoming ever more chaotic.

And the problem is that as long as we keep pumping greenhouse gasses into the sky, there will be no new normal to adapt to. Stability will not be available.
