Living with less water: Lessons for Californians – and the rest of us – from a New Mexico village

Krista Langlois | Feb 26, 2014 05:00 AM

Let me start right off by saying that I failed. Miserably. Last summer I moved to western Colorado after spending most of my 29 years in exceptionally rainy places, and amid discussions of water rights and fights and rivers drying up and unraveling, I decided it would be a good idea to limit my own water footprint. For one week, I’d live on just five gallons of water a day. Then I’d write about it.

I could envision two possible endings:

Scenario One: While standing naked in the bathtub, smugly dribbling water over my head from a cup dipped in a bucket, I conclude that I must be in the 99th percentile of environmentally conscious Americans because living on five gallons a day requires little sacrifice. My houseplants thrive, I remain clean and good-natured, and the brilliant essay I planned to write suffers because it was too easy.

Scenario Two: One week into my experiment, I am ragged and filthy. My plants have withered and I've been shunned at work for peeing in a chamber pot under my desk. I am desperate for a hot shower, and when I finally turn on the faucet and step into the tub, I experience deep revelations that lead to a brilliant essay about limiting my water supply.

Scenario Three never made an appearance in my daydreams, but this is what really happened: It's Monday night – a mere three days after my resolution to live for a week on limited water ­– and I am sitting in bed freshly showered. I did not shower with a bucket. In other words, I didn't even make it to the end of the week.

***

For me, five gallons a day was a quirky experiment. For the 17 California communities on a list released last month by state health officials, it may become reality: As drought tightens its grip on the state, each community is at risk of running out of drinking water within 100 days. Officials are discussing trucking in water as a possible solution.

In one such place, a town of 1,200 called Lompico, water comes from underground aquifers replenished by rainwater. The problem is, there hasn’t been much rain lately: California received an average of just 7 inches in 2013, compared to their usual 22, and the Sierra Nevada snowpack that feeds many reservoirs is at 12 percent of normal. Lompico residents have been asked to cut their water usage by 30 percent, but as Water District Board president Lois Henry pointed out to the San Francisco Chronicle, “We live in the Santa Cruz Mountains. People don't have lawns. They don't have gardens. How are they going to conserve 30 percent?"

California isn’t the only state to face water shortages; residents of Magdalena, N.M., might be able to offer a few water-conserving suggestions. Last June, Magdalena’s sole well ran dry, and for several weeks Socorro County officials had to truck in water from the county seat, 30 miles away. For a while, families received two plastic water bottles and a five-gallon tank per day. The medical clinic shut its doors. Restaurants switched to disposable plates. Tourism effectively ceased, and some people living in rental properties packed their bags and moved on. It was like a glimpse into a drought-wracked dystopian future ­– or a not-so-distant future, if predictions that the California drought will persist for several months or longer prove accurate.

Climate-based wolverine listing delayed by scientific disputes

Sarah Jane Keller | Feb 25, 2014 11:05 AM

With thick fur and snowshoe-like feet, wolverines are well-adapted to live in snow caves and run straight up mountains. Their high elevation lifestyles have helped them stay out of harm’s way in recent decades, and stage a slow comeback from the rampant carnivore persecution of the early 1900s. Though elusive and tenacious, they won’t be insulated from human impacts forever. They face a precarious future as climate change eats away at the snowpack they need.

That’s why the U.S. Fish and Wildlife Service is proposing to add them to the endangered species list, even as a handful of wide-ranging wolverines are venturing into states where they haven’t been seen for generations. The agency was slated to make a listing decision earlier this month as part of a legal settlement with environmental groups. But reputable wolverine biologists have criticized the scientific underpinnings of the agency’s proposed listing decision, especially the parts related to snowpack. Now, the FWS is delaying the decision for another six months so they can reconvene with scientists about wolverine habitat and climate impacts to it.

If wolverines are listed, they will join polar bears in having the dubious distinction of receiving federal protection in the name of climate change. Even if that can’t do much to curb climate impacts, it would renew discussions about federal and state wildlife managers reintroducing experimental populations of wolverines in higher elevation refuges like Colorado, to help maximize their survival prospects in the U.S.

A listing will also send a strong message about the fragile future of mountain snowpack that so many people depend on for water. But the prospect of a decision based on climate models, rather than more traditional, tangible, threats is already attracting attention. As Bob Inman, a wolverine biologist for the Wildlife Conservation Society in Montana wrote in his peer review comments, “The magnitude of the precedent that this ruling establishes warrants careful scrutiny.”

Colorado first in the nation to regulate oil and gas industry’s methane emissions

Sarah Gilman | Feb 25, 2014 10:10 AM

The home of the West’s most pitched battles over oil and gas development is once more in the news for major energy policy reforms. On February 23, Colorado’s Air Quality Control Commission voted in significantly stricter statewide rules governing air pollution from oil and gas development, including the nation’s first state-level controls on the industry’s emissions of methane – a much more potent greenhouse gas than CO2.

The rules, which officials will begin implementing this year, “require companies to detect leaks and fix them (and) install devices that capture 95 percent of emissions — both volatile organic compounds and methane,” reports Bruce Finley for the Denver Post. State officials estimate that they will reduce emissions of volatile organic compounds (or VOCs), which contribute to the formation of lung-damaging, smog-making ozone, by 92,000 tons, and methane, by tens of thousands of tons. The measures are part of the state’s efforts to bring the urban area’s air into compliance with federal health standards.

Air quality hasn’t been helped by a recent drilling revival, driven in part by advances in the oil and gas extraction process known as hydraulic fracturing, or fracking, wherein a mix of water, sand and chemicals are fired into the ground to stimulate hydrocarbon production. With rigs moving closer to more communities, several have banned or otherwise voted to restrict the practice in hopes of avoiding accompanying air and water pollution, as well as public health impacts. A recent study in Environmental Health News has stoked those fears with the finding that women who live near gas wells in rural Colorado are more likely to have babies with congenital heart and neural tube birth defects.

With many enviros staking out hardline positions – calling for more local bans and even a statewide moratorium on fracking – the state, the industry and some environmental groups have been working to find common ground on how to lesson industry’s impacts. The new air quality rules are a good example, brokered as they were with the Environmental Defense Fund and the major energy companies Anadarko, Noble and EnCana.

The terrifying yet awesome beauty of the gas patch

Jonathan Thompson | Feb 24, 2014 08:40 AM

Contrails feather out across the hard-blue February sky, and the unforgiving light of mid-morning  accentuates the bright reds, oranges, and synthetic blues of the fake flowers at the foot of scattered headstones, mostly engraved with Hispanic names. A Virgen de Guadalupe statue, hands clasped together, miniature rosary and cross hanging from her neck, stares down at the dirt, sun-cracked and blemished by not one blade of grass or weed or leaf, as though this cemetery is both meticulously cared for and utterly ignored, all at once. A constant high roar, or perhaps a hiss, drowns out the sound of my camera’s shutter click, as I’m careful not only to get the shrine in the frame, but also the condenser towers, like giant robot phalli, looming frighteningly close.

ShrineGasPlant

Like nearly every other acre of the landscape in this swath of northwestern New Mexico, the St. Mary’s Cemetery has been inundated by the gas patch. Its graves butt up against a big fence, just behind which are the tangle of big pipes and cooling towers that are part of Conoco-Phillips’  San Juan Gas Plant, one of a handful of similar facilities in this neighborhood of beaten down trailers, modest homes and a houseboat beached inexplicably in a plot of sand next to an arroyo.

I look around furtively before shooting another photograph, just in case someone suspects me of being a terrorist scout, casing the joint for a future attack. If questioned, I’ll tell them I’m photographing small graveyards in the region for a cultural project. But what if I were to tell the truth? What would I tell them then?

That I’m looking for glimmering shards of beauty? Here? In the gas patch?

Few places are as imbued with the energy economy, and its detritus, as San Juan County, New Mexico. This is not a sudden boomtown like, say, Williston, N.D. It’s been in a chronic state of boom and bust since the 1920s, when oil was discovered nearby. Uranium mines and mills, coal mines and massive power plants and natural gas followed. Workers and wildcatters and corporations came in droves, drilling at least 40,000 holes in the earth over time, some as deep as 14,000 feet, causing the sleepy little farming town of Farmington to balloon into a bustling, sprawling mini-city. The county’s population jumped from 18,000 in 1950 to 53,000 a decade later; today it’s around 130,000.

Rate of undocumented immigrants winning deportation cases is on the rise, many still detained

Tay Wiles | Feb 22, 2014 05:00 AM

It’s an interesting moment for immigration reform in the United States. The very phrase has come to symbolize the failure of the Obama Administration to push much meaningful change through Congress, since the Senate bill to create a 13-year path to citizenship for undocumented migrants floundered amongst GOP opposition last year. Perhaps it was the federal shutdown that threw reform off the rails. Or maybe Republicans just aren’t ready to stop shooting themselves in the foot by alienating one of the fastest growing minorities in the country.

Though politicians on both sides of the aisle are still demanding to see reform in 2014, it’s unclear how quickly the issue will make a serious comeback. But new data from the Transactional Records Access Clearing House, a research group at Syracuse University, show that an increasing number of unauthorized immigrants are beating deportation charges. Several hundred thousand undocumented people are deported yearly – 368,644 in fiscal year 2013 – for anything from running a stop sign or crossing the border illegally to committing a violent crime.

The rate of these deportation cases that ICE is losing is now higher than at any time in the last 20 years. As the Associated Press reports, over 78 percent of those facing deportation in Phoenix have won their cases this fiscal year, a marked change from 35 percent in fiscal year 2010. Since October 2013, immigration judges have seen 42,816 cases across the country, and allowed nearly 50 percent of those defendants to stay in the U.S. at least temporarily, up from just 24 percent five years ago. California and Oregon show some of the strongest shifts toward leniency. Utah is one of the few states to resist that change, with judges there still more likely to side with Immigration and Customs Enforcement (ICE) in booting migrants out of the country.

So why has ICE been losing more cases? “We really don’t know,” says Susan Long, a statistician and sociologist with TRAC. “That would be a good question to ask ICE.” (At the time this story was published, ICE had not responded to requests for comment.) Long is wary of drawing conclusions about the reasons. because the trend could be caused by a variety of factors. But one thing’s for sure – she and other researchers were surprised by the numbers.

To begin with, Long had thought that the rate of deportation would have actually gone up thanks to a 2011 federal initiative. The push  to close thousands of pending deportation cases in an effort to trim the massive backlog and prioritize immigrants who truly pose a threat to public safety, led Long to believe that the rate of immigrants able to fight off deportation would go down, not up. In other words, a more focused deportation strategy was supposed to result in fewer court cases but a higher rate of deportation for those that did in fact make it to court.

For native birds, cities may spread disease while still providing sanctuary

Ben Goldfarb | Feb 20, 2014 11:15 AM

Ours is an increasingly urban nation – over 80 percent of the U.S. population now dwells in cities and towns, a figure that’s only rising. Nowhere is that trend more pronounced than in the West: Phoenix, Salt Lake City and Denver are among the country’s fastest-growing cities. Our metropolitan migration has environmentalists and planners dreaming of efficient high-density housing and a public transportation revolution. But before we wholeheartedly embrace urban living, it’s worth asking what the growth of American cities means for our wildlife.

Two recent studies approach that question in very different ways. The first, published this month in the journal PLOS ONE, suggests that cities could be hazardous to the health of animals dwelling in and around urban areas. To arrive at that conclusion, researchers at Arizona State University trapped house finches – small, crimson-breasted birds native to southwestern deserts – across a range of habitats in the Phoenix area, from the heart of downtown to a park twenty miles outside the city, and examined them for parasites and a disease called avian poxvirus. What they found was troubling: Finches that lived in areas with higher human populations and greater habitat disturbance were more likely to be infected.

What explains the urban illness? One possibility, says Kevin McGraw, the study’s senior author, is that bird feeders encourage high population densities and unhygienic conditions that lead to infection. “When you’re around many other members of your species, you’re more likely to get infected,” explains McGraw. “Dirty birdfeeders themselves might also be a route of transmission.” The pollutants, pesticides, and junk food that urban birds encounter may also make the creatures more susceptible to illness by putting stress on their bodies. “Anytime you’re stressed, you could be immunologically compromised,” McGraw says.

Madhusudan Katti, an ecologist at California State University, Fresno who has studied birds throughout the Southwest, proposes a fourth hypothesis. “Because food is readily available in cities, birds that might die in the wild survive,” says Katti. “You can cause an unhealthy population to persist.”

Katti’s own research suggests that the relationship between birds and cities is immensely complicated. To wit: Abert’s towhee is a large sparrow, native to the Sonoran Desert, which ordinarily sticks to riparian corridors. In Phoenix, however, where manmade features like sewage ponds and groundwater recharge basins provide watery habitat, Katti found that the towhee sometimes strays miles from stream channels. “Desert birds take advantage of any water, anywhere,” he says. “Cities create urban oases, which bring in a lot of opportunistic species.”

But those opportunists don’t always flourish. Cities and other human-altered habitats can become ecological traps that lure wildlife with the promise of easy food and shelter, and then suppress reproduction and survival. After all, cities, with their cats and collision-inducing windows, are perilous places for birds, and our well-intended aid may not help. “We attract them with bird feeders, but I wonder about the nutritional value of the food we’re giving them,” says McGraw. “They’re eating the equivalent of bird candy.”

The task for planners and conservationists, then, is to ensure that cities function less like traps and more like oases. Another study, published in Proceedings of the Royal Society B last week by researchers affiliated with U.C. Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS), offers a partial solution to that challenge. The paper, a sweeping analysis of urban plant and bird biodiversity in 147 global cities (including some in the American West like Los Angeles, Tucson and Seattle), found that cities retain a surprisingly rich suite of native species. Sure, urban areas can’t match the diversity of undeveloped landscapes, but they’re not homogenous wastelands of pigeons and starlings, either: the median city contained 112.5 bird species, only 3.5 of which were exotic. (If you don’t think 109 native birds is impressive, try naming 50 in your hometown, and your neighbor’s cockatiel doesn’t count.) “Most people think of cities as concrete jungles that aren’t important for conservation, but they actually support 20 percent of bird species worldwide,” says Myla Aronson, a Rutgers University biologist and lead author.

The NCEAS study also demonstrates that if an urban area’s vegetative cover increases, so does its species density. “That’s a message to urban planners about the value of green space,” says Frank Davis, director of NCEAS. “What you plant, the way you design streamside corridors – there are ways to make urban areas more friendly to biodiversity.”

To be sure, increased green space isn’t a panacea for wildlife health: Although habitat loss has been associated with the spread of animal disease elsewhere in the world, an extra park or two likely won’t prevent birds from crowding around dirty feeders stocked with non-nutritious seed. The presence or absence of high-quality green space habitat, says McGraw, still lies within the “big black box of stress” — meaning it’s a variable that could compromise birds’ immune systems, but, compared to other factors like feeder hygiene, is so complex that it’s hard to directly connect to animal health. “We still don’t understand a great deal about disease dynamics in urban areas,” adds Katti (who’s also one of the authors of the NCEAS study).

When it comes to retaining native species, however, creating green space is still the best tool urban planners have. Los Angeles’ Debs Park, site of a new Audubon nature center, hosts over 140 different avian species, Phoenix is using a U.S. Fish and Wildlife Service grant to create nesting habitat, and surveys on the green space-rich Berkeley campus suggest that avian diversity hasn’t declined in the last 75 years. “We go to cities and appreciate the language and culture, but there’s another side, and that’s their nature,” says NCEAS’ Davis. “It may be diminished biodiversity, but it’s still native biodiversity, and we can’t give up on trying to restore it.”

Groundbreaking “Sea Ice Atlas” aids Arctic planning and is really cool to boot

Krista Langlois | Feb 19, 2014 01:35 PM

Back in the dark ages of the 1960s, the science of ice forecasting – predicting how much ice will be choking Arctic seas in a given month – was based more on intuition than science. Forecasters relied largely on memory and anecdotal observations, with results about as fallible as you’d expect. Sometimes, the dearth of information caused trouble for forecasters, like the time they sent barges laden with Alaska pipeline materials into the Bering Sea and accidentally trapped them in the ice for days.

Thanks to satellite technology, today’s Arctic-going vessels have a better chance of avoiding such mishaps. But without a solid historical record to contextualize the data, there are still a lot of unknowns. A digital Sea Ice Atlas is out to change that, bringing 160 years' worth of observation together with modern GIS mapping to take forecasting into the 21st century.

With temperatures at record highs and Alaskan sea ice at record lows, activity above the Arctic circle has spiked. Oil, fishing, tourism, military and shipping officials have each expressed the need for a reliable resource to help them navigate not only the ever-shifting northern seas, but also the future of the Arctic itself. Dael Devenport, a National Park Service archeologist, plans to use the atlas to predict coastal erosion and preserve archeological sites at the Bering Land Bridge National Preserve.

Though the atlas was mostly created for people who work in the Arctic, the interactive maps and historical record are free for anyone with an internet connection, and are just plain cool to play around with – especially if you’re in the midst of a mid-winter heat wave and dreaming of snow and ice, as we are at the HCN headquarters in Paonia, Colo.

$80k a year with a high school diploma: Why it's difficult to replace coal-mining jobs

Emily Guerin | Feb 18, 2014 11:15 AM

On a Saturday in early February, the wooden bleachers at the old middle school in Paonia, Colo. were filled with men in boots, camouflage hats and Carhartt jackets. Most were miners who had recently been laid-off by one of the North Fork Valley’s three coalmines. Stern-faced women sat beside them, some wearing pins that said, “I dig mining!” One man wore a miner’s helmet covered in stickers from the coal company that had just laid him off. Right above the brim he’d stuck his most brazen sticker, which read “Stop the war on coal, fire Obama.”

The Democratic state senator representing the district had called the meeting and lined up a series of speakers to offer advice and encouragement to the out-of-work miners. During a presentation about re-training programs, a miner named Cliff Brewer spoke up.

“I’m all for the re-training programs and I’ve looked into them already, but the fact of the matter is, it does not support our life. A $10/hour job, that’s not enough to keep us here,” he said, to murmurs of agreement from the crowd. “Is there anything that would train a miner to make the kind of money he’s used to making underground?”

With a few exceptions, the answer to that question is no. “The city of Montrose (Colo.) hired patrol officers starting at $50,000 a year,” said John Jones, the director of Delta Montrose Technical College, as he touted the school’s law enforcement training program to the miners. “It’s not the kind of wage that a miner makes, but it’s a good living wage.”

But for miners accustomed to making – and spending – nearly double that amount, it doesn’t feel like a living wage. The transition can be especially hard for those miners who only have high school diplomas. “I don’t have a college degree and I make 80 grand a year, you tell me another job that’s going to pay me $80,000 a year,” Brewer said when I talked to him after the meeting. “There’s none. I’m going to go where the mines are at and unfortunately that’s not here anymore.”

Miners willing to move may find jobs in coal-producing regions that are still booming, like Wyoming’s Powder River Basin or the Illinois Basin in Western Kentucky. But for those who want to stay put and find new jobs in places like Eastern Kentucky, West Virginia and, at the moment, Paonia, Colo., it can be hard to accept the severe pay cut.

Terrorists, infrastructure porn and our fragile energy systems

Jonathan Thompson | Feb 17, 2014 08:00 AM

They came shrouded by the early morning darkness near San Jose, Calif., equipped with night-vision goggles, AK-47s and an apparent lust to spill some transformer fluid. They cut some telephone cables and then, according to the Wall Street Journal:

Within half an hour, snipers opened fire on a nearby electrical substation. Shooting for 19 minutes, they surgically knocked out 17 giant transformers that funnel power to Silicon Valley. A minute before a police car arrived, the shooters disappeared into the night.

It’s a dramatic tale, and — as is any story about a group of people shooting into the night with assault rifles — scary, too. The substation was a big one, and the transformers critical pieces of equipment in keeping the electrical grid humming along smoothly. And it doesn’t take a flurry of bullets to put one out of commission and take out power to millions: Simple human error, a branch rubbing against a wire, or a bird landing on or a squirrel chewing on the wrong wire can do that. In this case, grid operators were able to bypass the substation without cutting off power to Silicon Valley. Disaster averted.

TransmissionOutages
Each year, there are more than 1,500 unplanned outages in the Western Grid. Weather is the main cause; vandalism or terrorism are extremely rare. Source: WECC.

When the attack happened last April, it was at first called a random act of vandalism. Then, as premeditation became apparent, it was upgraded to sabotage. Conspiracy theory-leaning websites, meanwhile, insisted it was an act of terror, and that something bigger might be on its way. They weren’t the only ones. Last week, the Wall Street Journal whipped the news media into a frenzy with a report that has former Federal Energy Regulatory Commission Chairman Jon Wellinghoff saying that it was, indeed, a terror attack, and that it could be a “dress rehearsal” for a much larger action against the grid. That prompted leading Democratic lawmakers to send a letter to FERC, asking it to consider raising security standards on the grid.

Those of you who are regular readers of HCN's Goat Blog might remember my story about the attack shortly after it happened, and about how I thought we shouldn’t worry about terrorists: Climate change, not to mention birds and tree branches and mylar balloons, are a bigger threat to the grid. The new information doesn’t change my mind. With no disrespect to Wellinghoff and all the politicians worried about physical attacks to the grid, I say this: Yes, you should be concerned about the viability of our energy infrastructure. Yes, you should be putting some cash into making it more robust and regulating it more strictly. But, no, terrorism is not the biggest threat. Far from it.

Owls react to megafire and climate trends in central Colorado

Tay Wiles | Feb 15, 2014 05:00 AM

In the 1980s, when ecologist Brian Linkhart first started digging around in old woodpecker holes in Colorado for flammulated owls – fuzzy, black-eyed creatures weighing just one to two ounces – his research was all about the birds. He wanted to understand if and where the secretive little animals were breeding – questions he pursued purely because the owls fascinated him.

But after decades on the job, the Colorado College professor has turned his attention to what these owls can tell us about larger phenomena, like megafires and climate change.

Not many people have extensively studied “flams,” as Linkhart calls them, because they’re elusive: The birds are nocturnal and sing for only a short span of time during mating season, and even then quietly. Linkhart has studied flammulated owls longer and more deeply than anyone, which puts his research in a unique spot to evaluate how long-term trends like warming temperatures may impact the owls. It takes decades of observation for those cause-and-effect relationships to exit the speculative realm and come into relief – and that’s exactly what’s happening with Linkhart’s data.

I the early 2000s, he first started seeing Colorado flams breeding earlier in the year than they used to. “That was one of my first clues,” Linkhart says, that the owls were responding to changes in the climate. Then he began to notice fewer offspring and evidence of siblicide in broods. More recently, these changes inspired Linkhart to examine the larger trends that could be causing them.

Linkhart has found that the earlier breeding cycle has a direct correlation with warmer spring temperatures. Precipitation declines over many years in the Manitou Experimental Forest, one of his study areas in the Pike National Forest southwest of Denver, are likely a factor in the decrease in offspring. Flams usually produce two or three fledglings a year, but over the past 15, Linkhart has seen an average closer to one. With less moisture between January and June, he thinks the shrubs, flowers and vegetation that insects – the owls’ primary food source – depend on, aren’t growing as abundantly as they used to and support fewer insects. That makes for hungrier flams. Increasingly parched summers have also made a major predator, red squirrels, more aggressive. With trees producing fewer seeds for squirrels to eat, the rodents have been pillaging flam nests more often than usual, to feast on eggs.

These temperature and precipitation trends may be a result of the last half-century of climate change, though it’s difficult to prove. Either way, future climate change will no doubt exacerbate the trends.
