In a dramatic reversal of fortune compared to last year, an unusually dry winter is causing the level of Lake Mead, Nevada, to decline, making water managers increasingly anxious about supplying water to the thirsty Southwest.
The latest U.S. Drought Outlook shows continued dry conditions in the Southwest are likely for the rest of the winter.
During the past three years, the level of Lake Mead has followed a boom and bust cycle, dropping to a record low in 2010 during an intense drought, then recovering during 2011 thanks to record mountain snowfall, and now dropping again in the midst of a dry winter.
According to an article in the Las Vegas Review-Journal, water managers are forecasting the lake level to drop by about 13 feet due to the dry winter so far. As the newspaper reported:
"In December, the U.S. Bureau of Reclamation was predicting a roughly 11-foot rise in Lake Mead over the next year. Now the bureau expects the nation's largest man-made reservoir to shed about 13 feet by January 2013.
One acre-foot equals about 326,000 gallons, which is enough water to supply two average valley homes for one year. At current consumption levels, the 2.45 million acre-foot reduction in Lake Mead's forecast since last month represents enough water to supply the entire Las Vegas Valley for a decade."
During the past 11 years, a particularly dry and warm climate has lingered in Utah, Nevada, Arizona and Southern California, leading to reduced flow along the Colorado River. In fact, scientists have already shown that the stress on the water resources in the Southwest region is consistent with the effects of a warmer climate, and that increased emissions of heat-trapping gases are linked to recent changes in river flows and winter snow pack. Adding to the region's water challenges is the fact that cities that draw water from Lake Mead, such as Las Vegas, have grown in recent years and are further taxing the water supply.

Consider it a taste of the future: the fire, smoke, drought, dust, and heat that have made life unpleasant, if not dangerous, from Louisiana to Los Angeles. New records tell the tale: biggest wildfire ever recorded in Arizona (538,049 acres), biggest fire ever in New Mexico (156,600 acres), all-time worst fire year in Texas history (3,697,000 acres).
The fires were a function of drought. As of summer’s end, 2011 was the driest year in 117 years of record keeping for New Mexico, Texas, and Louisiana, and the second driest for Oklahoma. Those fires also resulted from record heat. It was the hottest summer ever recorded for New Mexico, Texas, Oklahoma, and Louisiana, as well as the hottest August ever for those states, plus Arizona and Colorado.
Virtually every city in the region experienced unprecedented temperatures, with Phoenix, as usual, leading the march toward unlivability. This past summer, the so-called Valley of the Sun set a new record of 33 days when the mercury reached a shoe-melting 110º F or higher. (The previous record of 32 days was set in 2007.)
And here’s the bad news in a nutshell: if you live in the Southwest or just about anywhere in the American West, you or your children and grandchildren could soon enough be facing the Age of Thirst, which may also prove to be the greatest water crisis in the history of civilization. No kidding.
If that gets you down, here’s a little cheer-up note: the end is not yet nigh.
In fact, this year the weather elsewhere rode to the rescue, and the news for the Southwest was good where it really mattered. Since January, the biggest reservoir in the United States, Lake Mead, backed up by the Hoover Dam and just 30 miles southwest of Las Vegas, has risen almost 40 feet. That lake is crucial when it comes to watering lawns or taking showers from Arizona to California. And the near 40-foot surge of extra water offered a significant upward nudge to the Southwest’s water reserves.
The Colorado River, which the reservoir impounds, supplies all or part of the water on which nearly 30 million people depend, most of them living downstream of Lake Mead in Los Angeles, San Diego, Phoenix, Tucson, Tijuana, and scores of smaller communities in the United States and Mexico.
Back in 1999, the lake was full. Patricia Mulroy, who heads the water utility serving Las Vegas, rues the optimism of those bygone days. “We had a fifty-year, reliable water supply,” she says. “By 2002, we had no water supply. We were out. We were done. I swore to myself we’d never do that again.”
In 2000, the lake began to fall -- like a boulder off a cliff, bouncing a couple of times on the way down. Its water level dropped a staggering 130 feet, stopping less than seven feet above the stage that would have triggered reductions in downstream deliveries. Then -- and here’s the good news, just in case you were wondering -- last winter, it snowed prodigiously up north in Colorado, Utah, and Wyoming.
The spring and summer run-off from those snowpacks brought enormous relief. It renewed what we in the Southwest like to call the Hydro-Illogic cycle: when drought comes, everybody wrings their hands and promises to institute needed reform, if only it would rain a little. Then the drought breaks or eases and we all return to business as usual, until the cycle comes around to drought again.
So don’t be fooled. One day, perhaps soon, Lake Mead will renew its downward plunge. That’s a certainty, the experts tell us. And here’s the thing: the next time, a sudden rescue by heavy snows in the northern Rockies might not come. If the snowpacks of the future are merely ordinary, let alone puny, then you’ll know that we really are entering a new age.
And climate change will be a major reason, but we’ll have done a good job of aiding and abetting it. The states of the so-called Lower Basin of the Colorado River -- California, Arizona, and Nevada -- have been living beyond their water means for years. Any departure from recent decades of hydrological abundance, even a return to long-term average flows in the Colorado River, would produce a painful reckoning for the Lower Basin states. And even worse is surely on the way.
Just think of the coming Age of Thirst in the American Southwest and West as a three-act tragedy of Shakespearean dimensions.
snip
We have already experienced close to 1º C of that increase, which accounts, at least in part, for last summer’s colossal fires and record-setting temperatures -- and it’s now clear that we’re just getting started.
The simple rule of thumb for climate change is that wet places will get wetter and dry places drier. One reason the dry places will dry is that higher temperatures mean more evaporation. In other words, there will be ever less water in the rivers that keep the region’s cities (and much else) alive. Modeling already suggests that by mid-century surface stream-flow will decline by 10% to 30%.
Independent studies at the Scripps Oceanographic Institute in California and the University of Colorado evaluated the viability of Lake Mead and eventually arrived at similar conclusions: after about 2026, the risk of “failure” at Lake Mead, according to a member of the Colorado group, “just skyrockets.” Failure in this context would mean water levels lower than the dam’s lowest intake, no water heading downstream, and the lake becoming a “dead pool.”

White Tigers do not exist in the wild, they are purposefully inbred in captivity to meet the demand of the paying public. The kind of severe inbreeding that is required to produce the mutation of a white coat also causes a number of other defects in these big cats.
The same gene that causes the white coat causes the optic nerve to be wired to the wrong side of the brain, thus all white tigers are cross eyed, even if their eyes look normal. They also often suffer from club feet, cleft palates, spinal deformities and defective organs.White Tigers do not exist in the wild, they are purposefully inbred in captivity to... more

The state of water in our world currently is endangered. Pollution, privatization, waste, climate change effects and lack of attention to this most crucial life crisis is bringing us to the brink as a species. And we have no one to blame but ourselves. In trying to assess in my own mind why something so basic and necessary to our lives is given such little attention it is frustrating to say the least. Especially in this age of technology when we see through our modems and other devices so much more information than ever before being shared on this and so many other global crises.
When you look at the world as a whole and realize that 3/4 of it live in poverty and that the majority of those areas also do not have access to potable water/sanitation, the corrolation is obvious. Yet, we as a species even in the 21st century are failing at even providing the basic necessities of life to ourselves and others. Why? Why is water so unimportant to so many even though they know they cannot live without it? Is it ignorance? Arrogance? Or is it because there are those who have been made to believe that we will always have what we need because money can buy you anything even at the expense of taking it from others.
Just look at the levels of pollution in our global waterways. Industry and nitrogen fertilizer rich agriculture alone have managed to kill some of the major river systems of the world and made dead zones devoid of the oxygen marinelife needs to survive. The burning of fossil fuels, deforestation and other destructive land uses (fracking, tarsands extraction, strip mining, mountain top removal) are culminating to push our atmosphere and water to the tipping point. We are now seeing more extreme events (storms, floods, droughts) around the world which are the results of human forcings on the natural cycles of the planet to the point where we have actually affected the hydrologic cycle. And this is now being touted as the "new normal."
This has already resulted in billions of dollars of lost agriculture to the world, most recently in Thailand where much of their rice crop has been destroyed from unprecedented floods that are also happening globally simultaneously, as well as extreme droughts on both sides of the world. This then has a domino effect regarding food prices and the ability to live. And with predictions of these events (extreme floods and droughts) becoming more severe with rainfall patterns changing, the entire way the world grows food is being challenged. And in the process more fall into poverty, illness, war and hopelessness as those with more green paper think it buys them rights to the resources of Earth that belong to all mankind.
So for me there can only be one main reason why this has happened. We have strayed from our humanity. We have allowed materialistic manmade forces to infiltrate our consciousness and perceptions of life on this Earth and those skewed perceptions are now killing us and in the process destroying this Earth for future generations.
And it is the hope of changing those perceptions and bringing a paradigm shift in thinking that is now bringing people out into the streets worldwide calling for justice and equality. Calling for accountability for those who have stripped this Earth of all that was once good in exchange for a world of their making that can sustain no one, not even themselves. The false illusion of money's worth in comparison to the limitless value of this Earth coupled with delusions of grandeur built on sand in failing to understand the true meaning of humanity and its true purpose must now be challenged. And that right now is the hope we have as a species... awareness, awakening, gnosis.
The inate instinct that tells us as humans that we are one with this planet and that to destroy her destroys us. This is the lesson we must learn. This is the perception we must impart to others. We are at the brink, but we don't have to go over. There are ways to heal her and ourselves. We can join globally with likeminded individuals who know the stakes and make this shift happen with our thoughts and our actions. We can reclaim our humanity and in the process save ourselves. It won't be easy. However, the alternative is simply not an option.
Water is life, it is our life, it is the blood of Earth.
And it is worth fighting for.The state of water in our world currently is endangered. Pollution, privatization,... more

Earlier this month, officials in the South Pacific island nation of Tuvalu had to confront a pretty dire problem: they were running out of water. Due to a severe and lasting drought, water reserves in this country of 11,000 people had dwindled to just a few days' worth. Climate change plays a role here: as sea levels rose, Tuvalu's groundwater became increasingly saline and undrinkable, leaving the island dependent on rainwater. But now a La Niña–influenced drought has severely curtailed rainfall, leaving Tuvalu dry as a bone. "This situation is bad," Pusinelli Laafai, Tuvalu's permanent secretary of home affairs, told the Associated Press earlier this month. "It's really bad."
So far Tuvalu has been bailed out by its neighbors Australia and New Zealand, which have donated rehydration packets and desalination equipment. But the archipelago's water woes are just beginning — and it's far from the only part of the world facing a big dry. Other island nations like the Maldives and Kiribati will see their groundwater spoil as sea levels rise. Texas, along with much of the American Southwest, is in the grip of a truly record-breaking drought — even after days of storms in the past month, Houston's total 2011 rainfall is still short of its yearly average by a whopping 2 ft., or 60 cm. Australia has experienced severely dry weather for so long, it's not even clear whether the country is in a state of drought, or more worryingly, a new and permanent dry climate that could forever alter life Down Under. "Climate-change impacts on water resources continue to appear in the form of growing influence on the severity and intensity of extreme events," says Peter Gleick, one of the foremost water experts in the U.S. and head of the Pacific Institute, an NGO based in Oakland, Calif., that focuses on global water issues. "Australia's recent extraordinary extreme drought should be an eye-opener for the rest of us."

Far from being "alarmist," predictions from climate scientists in many cases are proving to be more conservative than observed climate-induced impacts.
The warnings were dire: 188 predictions showing that climate-induced changes to the environment would put 7 percent of all plant and animal species on the globe - one out of every 14 critters - at risk of extinction.
Scientists have been quite conservative in a lot of important and different areas. - Naomi Oreskes, University of California, San Diego
Predictions like these have earned climate scientists the obloquy from critics for being "alarmist" - dismissed for using inflated descriptions of doom and destruction to push for action, more grant money or a global government.
But as the impacts of climate change become apparent, many predictions are proving to underplay the actual impacts. Reality, in many instances, is proving to be far worse than most scientists expected.
"We're seeing mounting evidence now that the scientific community, rather than overstating the claim or being alarmist, is the opposite," said Naomi Oreskes, a science historian with the University of California, San Diego. "Scientists have been quite conservative ... in a lot of important and different areas."
Biased science
A decade ago scientists predicted the Arctic wouldn't be ice-free in summer until 2100. But the extent of summer ice in the North has rapidly shrunk and today covers 70 percent of the area it did in 1979. Now some scientists think the Arctic could be naught but open water within 25 years.
In August, a team lead by University of York researcher Chris Thomas published a study showing that plants and animals are moving to higher elevations twice as fast as predicted in response to rising temperatures. They're migrating north three times faster than expected, they found
As for extinctions, earlier this year two scientists at the University of Exeter paired predicted versus observed annihilation rates. The real-world rates are more than double what the best computer modeling showed: While the studies, on average, warned of a 7 percent extinction rate, field observations suggested the rate was closer to 15 percent.
Oreskes has spent a career studying climate science. She finds ample evidence that climate scientists are indeed biased - just not in the way portrayed by politicians such as Texas Gov. Rick Perry, who claimed scientists paint a bleak picture to secure more research funding.
In reality, Oreskes said, scientists skew their results away from worst-case, doomsday scenarios. "Many people in the scientific community have felt that it's important to be conservative - that it protects your credibility," she said. "There's a low-end bias. It has led scientists to understate, rather than overstate, the impacts."
Media's fault, too
Not all scientists agree that they and their colleagues have deliberately downplayed impacts, of course.
But other scholars have noted the misperception - and argued the fault lies not just with scientists, but also with journalists reporting those findings.
In a notable 2010 study, the late William Freudenberg, a University of California, Santa Barbara, researcher who studied science and the media, found that new scientific findings are more than 20 times likely to show that global climate disruption is "worse than previously expected" rather than "not as bad as previously expected."
He drew two conclusions from the assessment, one for scientists and one for journalists:
Scientists should be more skeptical toward supposed "good news" on global warming. And reporters, he warned, "need to learn that, if they wish to discuss 'both sides' of the climate issue, the scientifically legitimate 'other side' is that, if anything, global climate disruption is likely to be significantly worse than has been suggested in scientific consensus estimates to date."
Inherent challenges
Of course, the science of climate modeling itself could be inherently biased. Predicting the future impact of emissions remains a difficult task, despite advances in the field over recent decades. Disparate elements can interact in surprising and additive ways that belie scientists' best assumptions.
That may be the case with the discrepancy between predicted and observed extinction rates, said Ilya Maclean, a researcher at the University of Exeter and lead author of the study, published in July in the journal Proceedings of the National Academy of Sciences.
Many studies he examined tie predicted extinction rates to just one factor - rising temperatures, say, or loss of habitat due to sea-level rise. But a changing climate can impact habitats and species in diverse and unexpected ways, he said.
"That's not to say there are always additive effects," Maclean said. "But that might be one of the reasons why predictions tend to be quite conservative."

Another soft, deep roar. Dr Patterson emerges from a side door, closing it behind her, and joins me on the porch. Koko makes a sign. Dr Patterson translates: “Visit. Do you.
“Oh, sweetheart,” she says to Koko, then turns to me: “She’d like you to go inside.” Over the years Koko has inadvertently become a poster child for the gorilla conservation movement. There are several subspecies of gorilla, and today, according to the International Union for Conservation of Nature, all are either endangered or critically endangered.
It’s rare that anyone gets to meet Koko up close. I find out just how seldom at the Gorilla Foundation offices when I’m told most of the staff there have only ever been outside her enclosure. A handful of celebrities, Leonardo Di Caprio and Robin Williams included, plus a few business leaders have had the pleasure, but this was to raise her profile or secure donations for the foundation. Few journalists have had the opportunity, and I’m told none has spent as long as I will – an hour-and-a-half – in her company.http://tinyurl.com/6yhoct2Another soft, deep roar.

U.S. beefs up conservation efforts for endangered sea turtles
By Shelby Lin Erdman, CNN Radio
September 18, 2011 8:03 p.m. EDT
.
PHOTO: Loggerhead turtles will be divided into nine distinct population groups based on where they live, according to new regulations.
.
(CNN) -- The government has revised its rules on sea turtles to try to decrease the number killed every year and reduce the threats they face.
The new regulations place the Loggerhead turtle into nine distinct population groups, depending on where they live, instead of listing the marine animal as a single worldwide species. In all nine segments the turtles are listed as either threatened or endangered.
Officials at both the National Oceanic and Atmospheric Administration and the U.S. Fish and Wildlife Service, both responsible for overseeing the turtle conservation efforts, say they can better address the challenges the turtles face with the new geographical division.
Loggerhead or marine turtles live in tropical and subtropical waters around the world. The new "distinct population segments" for the turtles are: The Northeast Atlantic Ocean group, the Mediterranean Sea, the North Indian Ocean, the North Pacific Ocean, the South Pacific Ocean, the Northwest Atlantic, which includes the Gulf of Mexico and our Atlantic Coast, the South Atlantic Ocean, the Southeast Indo-Pacific Ocean and the Southwest Indian Ocean.
Researchers estimate more than 4,500 loggerheads are killed every year by commercial fishing, but environmentalists believe the number is probably much higher.
Commercial fishing is one of the biggest risks for the turtles, whether they live in the Indian, Pacific or Atlantic oceans, said Jim Lecky, the fisheries director for the National Oceanic and Atmospheric Administration.
"They all continue to be challenged by a number of threats, incidental capture in fishing gear, longlines, gill nets, trawl gear, trap and pot lines, which tangle turtles and other species, and dredges; all have incidental mortality of sea turtles in those fisheries," he said.
But Lecky says that's not the only threat for the turtles. "They are all also challenged by losses of habitat, degradation of nesting habitat. There still is direct harvest of eggs in adults ... at some level and they are all subject to vessel strikes."
The turtles are facing all those threats, but at different levels. So the new rules will allow fine-tuning of sea turtle conservation measures and regulations.
"We believe that this revised listing of the Loggerhead will help us and our partners to better focus recovery and conservation efforts by allowing us to take a more regional approach. But, again, the separation of Loggerhead into these population groups will not reduce our current conservation efforts," said Sandy MacPherson, the national sea turtle coordinator for the U.S. Fish and Wildlife Service.
MacPherson also told CNN Radio, "These new listings will help us to provide more focused recovery and conservation, as well as more focused threat analysis and evaluation of conservation successes."
The Center for Biological Diversity said in a statement that Loggerhead populations "need more protection to survive this century."
The rule revisions also included designating five regional populations as endangered species, which the group characterized as "a wake-up call that a whole host of threats, from oil spills, channel dredging and commercial trawling to longline and gillnet fisheries, continue to kill off turtles faster than the animals can possibly hope to reproduce."

When I started this blog several years ago these were the main areas of concern surrounding lack of access and potability of water in the world. And as with the climate crisis there have been many people out here talking about this and trying to educate people in doing what is necessary to provide this human right to all and warning of the consequences of not doing so. Unfortunately, though we have come some part of the way thanks to education, activism and the work of NGOs like Charity Water and others whose links I will also post here there is a long way to go.
As we are now seeing across the globe privitization is still trying to make more of a headway (even though we have seen initiatives in Germany, Italy and in the US in stopping this insidious move to control our global water supply) and moving to "commoditize" water in a market system sure to deprive the most poor of this basic human right even though it was declared so at the UN.
War is also playing a part. As a result of the tumultuous battles taking place in Libya the Great Manmade River Project started by Gaddafi (and this is not to be a political post so I will refrain from discussing opinions of him) which regardless of politics was and is an engineering marvel (I will post video on that here too) has been bombed and essentially shut down thereby cutting off water to more than half of Tripoli and other regions. Water is then still being used as a weapon of war which I find insidious regardless of who does it.
We are seeing as well increasing pollution levels in rivers, continued toxification of our oceans, acidification of our oceans, plastic garbage patches in our ocean's gyres that stretch for miles and on top of all of this, effects of a changing climate brought on by human activity that now threaten water supplies for billions of people worldwide and the systems that sustain our marinelife.
What are we to make of all of this? Are we finally reaching the point where more people will discover just how crucial water is to all of the systems that sustain us? If not, by the time critical mass is reached will it be beyond saving? For the next couple of weeks I will be writing and reporting on ways that we are affecting water and also ways we can save it. In the world we live in now water access has never been more of an urgent crisis.
That is why supporting organizations like Chartity Water are essential in working to provide equality, access and potability of water to the billions who now go without and that also includes adequate sanitation. It is unfathomable to believe that in the 21st century with all of the technological advances we have achieved that we still cannot provide basic sanitation and potable water for the people who live on this planet, even now as we explore other worlds. I say, let's take better care of the one we have now.
Please watch this video and look at the links to other organizations I will post here and reflect on what you can do to address this crisis locally and globally. Water is the one tie that binds us all. We cannot afford to lose it.

It offends me to no end the way they insist on politicizing everything environmental. Why does concern and honest, open discussion about the health of our world have to be cast in a liberal vs. conservative light. I want open debate concerning climate change, not baseless rhetoric.
"The idea Irene is a “harbinger” of climate change is just as reliable as the predictions uttered with sober certainty only 48 hours ago that the storm would cause unprecedented damage. But there is one trend we can rely upon to be true. Despite the complete absence of proof, for the foreseeable future, global warming alarmists will continue to spout theories about an increase in hurricanes and any other type of bad weather and assert they are the result of human activity that is cooking the planet. And much of the mainstream media will continue to report such wild theories as if they were verifiable facts."
I don't know whether or not Irene is a sign of anything, nor do I don't claim to, and especially not just for political reasons. I do know know we're actively taking a massive dump all over our planet, and that's just a horrible idea. Pond scum, Pa-tooie!

Amphibian species clings to life
Fewer than 200 mountain yellow-legged frogs are believed to exist. The Station fire [Los Angeles, California] destroyed habitat; now 104 have died mysteriously in a zoo's breeding tanks.

By Louis Sahagun, Los Angeles Times
August 17, 2011
.
One of the nation's most ambitious wildlife reintroduction efforts has suffered a setback with the deaths of 104 mountain yellow-legged frogs that had been rescued from the fire-stripped San Gabriel Mountains in 2009, authorities said Tuesday.
The federally endangered frogs, which recently metamorphosed from the tadpole stage, died in captive breeding tanks over the last several weeks at the Fresno Chaffee Zoo.
"We have two frogs left. We're trying to determine exactly what happened," said Scott Barton, director of the zoo, which is highly regarded for amphibian husbandry. "We were thrown a curve ball with a species that was new to us. It's been a humbling experience."
Barton said the facility may "send these two frogs off to see if someone else will have better luck."
The zoos in Fresno, Los Angeles and San Diego are involved in a public-private effort to pave the way for the Rana muscosa population to reestablish residency in Southern California.
For thousands of years, mountain yellow-legged frogs thrived in hundreds of streams cascading down the San Bernardino, San Gabriel and San Jacinto mountains.
Since the 1960s, the species has been decimated by fires, mudslides, pesticides, fungal infections, loss of habitat and the appetites of nonnative trout, bullfrogs and crayfish.
Today, fewer than 200 are believed to exist in nine isolated wild populations, including a group in the San Gabriel Mountains' Devils Canyon that survived the devastating Station fire.
According to U.S. Geological Survey ecologist Adam Backlin, a lead scientist in the recovery effort, "saving the mountain yellow-legged frog from extinction is turning out to be more difficult than anyone anticipated."
The Fresno zoo is not the only facility to have run into problems while trying to spur a jump in the population of the 3-inch amphibians.
Thirty-six tadpoles have not been seen since biologists at the San Diego Zoo's Institute for Conservation Research released them a year ago into a remote San Jacinto Mountain stream from which they had been absent for a decade, zoo officials said.
In 2006, seven mountain yellow-legged frogs — found three years earlier in a shallow pool in the San Bernardino Mountains after a large brush fire — died at the San Diego Zoo. Studies showed those frogs died of the same type of fungal infection that is killing frogs around the world.
The species' minuscule scattered population gives mountain yellow-legged frogs the distinction of being one of the most endangered amphibians on the planet.
"These frogs are very specific in their requirements. What works for one group may not work for another, which is why we have three zoos involved," Backlin said. "The problem is that zoos do not have the space, staff or the funds to keep many of these frogs, which need … almost constant attention.
"This program is still in its infancy," Backlin said. "I have high hopes."

Power and water are more interconnected than you might think, and that has serious consequences for a changing world, especially the American West.
Energy and water are as intertwined as the hydrogen and oxygen atoms in a bottle of Evian. California likes to think of itself as being ahead of the curve. So when the state set out to reduce greenhouse gas emissions, regulators did all the right things - stringent tailpipe standards for cars, tighter codes for buildings, higher renewable energy standards for utilities. Then they took one of the most aggressive energy-saving steps of all.
They started a campaign to save water.
The link between energy and water is not always apparent, but the two are as intertwined as the hydrogen and oxygen atoms in a bottle of Evian.
By now, everyone knows you save energy by turning out lights. And you conserve water by taking shorter showers. But it's just as true that saving water may be one of the most effective ways to save energy - and vice versa. "It's a 'buy one, get one free' deal," said Douglas Kenney, a professor at the University of Colorado Law School and the editor of an upcoming book that explores the nexus of water and energy.
In California today, the consumption of water accounts for 20 percent of the state's energy use. Much of that energy goes to heating water, but it takes power to gather, purify and distribute water, especially in places like southern California where water is piped hundreds of miles to supply Los Angeles' sprawling demands.
Nationally, energy production sucks more water from freshwater sources than any other sector except agriculture. It takes water to create the power we use to drive our cars, transport our groceries, and run our toaster ovens. Virtually every source of electricity in a typical American home or manufacturing plant - whether it comes from hydroelectricity, coal, natural gas, nuclear, biofuels, or even concentrated solar -- also requires water. Lots of water.
One reason for this problem is that electricity, as we've chosen to produce it, is pretty wet stuff. That's a growing problem, because in many places, finding water for energy isn't easy - and it's bound to get tougher as energy demands soar and climate change alters hydrological cycles in already arid regions. The energy sector is the fastest-growing water consumer in the United States, according to a January 2011 Congressional Research Service report [pdf].
Nationally, that's a challenge, but regionally it could be a calamity. As the Congressional Research report notes, "much of the growth in the energy sector's water demand is concentrated in regions with already intense competition over water."
Giant plug of concrete
The connection between energy and water - and the precariousness of that link in the western United States - is exemplified in a gigantic plug of concrete stopping the muddy Colorado River above Las Vegas, otherwise known as Hoover Dam. At the ceremony inaugurating the Depression-era public works project in 1935, then-Interior Secretary Harold Ickes noted proudly, "no better understanding of man cooperating with nature can be found anywhere."
Hoover Dam provided the two key ingredients - water and power - that freed the Southwest and southern California to go on a 75-year growth spurt. Lake Mead now supplies water to more than 22 million people, and it produces more than four billion kilowatts of electricity per year.
But Ickes likely never imagined how quickly man's cooperation with nature would disintegrate in the 21st century. In the American West, a burgeoning population created a double-whammy of surging power demands and dwindling freshwater supplies. The Colorado River, lifeblood of seven western states, is already as overdrawn as the federal treasury. Drought conditions during most of the 21st century have forced water managers to plan for a day when the region's vast system of dams and reservoirs no longer have enough water to store. Already, utilities have to scramble to respond on days when everybody in Phoenix, Las Vegas and Los Angeles wants to crank their air conditioners during the same heat wave.
Sustained drought and insatiable upstream water demand have drained Lake Mead to the point that experts are predicting it may soon be shallow enough to be in deep trouble. Despite near record snowfalls and runoff this year that raised its level from historic lows in January, Lake Mead is still 113 feet below "full pool" - and is filled to less than 50 percent of its capacity.
Three years ago researchers at Scripps Institution of Oceanography warned Lake Mead has a 50-50 chance of running dry by 2021 and that the reservoir's water level could dip low enough to reduce or stop electricity production as early as 2013. Although this year's run-off probably forestalled this dramatic assertion, utilities around the country have already been forced to reduce or stop electrical production because of water issues. According to a survey done in California's 2009 Water Plan Update [pdf], states from Virginia to Nevada and Texas to North Dakota have all curtailed energy development projects because of water quality or quantity concerns.
Wet stuff
One reason for this problem is that electricity, as we've chosen to produce it, is pretty wet stuff. Plug an appliance into an outlet and you might as well open a faucet as well. Running an average refrigerator all day uses about as much water as a ten-minute shower (without a low-flow showerhead). According to the U.S. Geological Survey, electric power generation accounts for nearly half of the nation's water usage [pdf]; it takes on average 21 gallons of water to produce one kilowatt hour of electricity. In the arid West, those numbers add up. A report by Western Resource Advocates [pdf] notes that "thermoelectric power plants in Arizona, Colorado, New Mexico, Nevada, and Utah consumed an estimated 292 million gallons of water a day in 2005 - approximately equal to the water consumed by Denver, Phoenix, and Albuquerque, combined."
Pretty much every step of energy production requires water, from mining to refining, processing to generation. Some of this water is "consumed" - evaporated as steam. Some of it is returned to watersheds in altered forms - like water heated during coal-fired electrical production and stored in cooling towers or ponds before being released - at higher temperatures - back into rivers. "Produced" water from coal-bed methane extraction releases underground water with high mineral content into watersheds. Deep drilling for seams of underground gas deposits rely on chemicals used in "fracking fluids," which contaminate water sources when they leak.
Other potential fossil fuel energy sources, like oil shale, require so much water during its production cycle that energy companies in Colorado have stealthily acquired rights to develop hundreds of thousands of acre feet of water, even before they've invented a viable technology to turn that rock into oil. An acre foot of water is 325,851 gallons, or enough to cover an acre of flat farmland with water a foot deep.
That's enough water to escalate the state's already intense water disputes into open warfare. "If oil shale energy does become commercially viable, it will be a huge new water drain," says Dan Luecke, a Colorado-based hydrologist and Western water consultant.

The US gets most of its Shrimp from Thailand's shrimp farms. Small ponds that are killing habitat at an alarming rate. Habitat the fishing cat (which provides a service by keeping the rodent population down) needs. Check out the packing and from Wal Mart to Whole Foods you will see it all seems to come all the way from Thailand.The US gets most of its Shrimp from Thailand's shrimp farms.

With its dark red and black stripes, spotted fins and long venomous black spikes, the lionfish seems better suited for horror films than consumption. But lionfish fritters and filets may be on American tables soon.
An invasive species, the lionfish is devastating reef fish populations along the Florida coast and into the Caribbean. Now, an increasing number of environmentalists, consumer groups and scientists are seriously testing a novel solution to control it and other aquatic invasive species — one that would also takes pressure off depleted ocean fish stocks: they want Americans to step up to their plates and start eating invasive critters in large numbers.
“Humans are the most ubiquitous predators on earth,” said Philip Kramer, director of the Caribbean program for the Nature Conservancy. “Instead of eating something like shark fin soup, why not eat a species that is causing harm, and with your meal make a positive contribution?”
Invasive species have become a vexing problem in the United States, with population explosions of Asian carp clogging the Mississippi River and European green crabs mobbing the coasts. With few natural predators in North America, such fast-breeding species have thrived in American waters, eating native creatures and out-competing them for food and habitats.
While most invasive species are not commonly regarded as edible food, that is mostly a matter of marketing, experts say. Imagine menus where Asian carp substitutes for the threatened Chilean sea bass, or lionfish replaces grouper, which is overfished.
“We think there could be a real market,” said Wenonah Hauter, the executive director of Food and Water Watch, whose 2011 Smart Seafood Guide recommends for the first time that diners seek out invasive species as a “safer, more sustainable” alternative to their more dwindling relatives, to encourage fisherman and markets to provide them.
“What these species need now is a better — sexier — profile, and more cooks who know how to use them,” she said. She has enlisted celebrity chefs to promote eating the creatures.
Scientists emphasize that human consumption is only part of what is needed to control invasive species and restore native fish populations, and that a comprehensive plan must include restoring fish predators to depleted habitats and erecting physical barriers to prevent further dissemination of the invaders.
“We are not going to be able to just eat our way out of the invasive species problem,” Dr. Kramer said. “On the other hand, there are places where this can be a very useful part of the strategy.”
The United States Fish and Wildlife Service is now exploring where it might be helpful. Models suggest that commercial harvest of Asian carp in the Mississippi would most likely help control populations there, “as part of an integrated pest management program,” said Valerie Fellows, a spokeswoman.
In practice, it is still unclear whether commercial fishing pressure could be high enough to have a significant impact, she said. The Army Corps of Engineers has spent millions of dollars to erect electronic barriers to keep Asian carp from moving from the Illinois River into the Great Lakes.
There are risks to whetting America’s appetite. Marketing an invasive species could make it so popular that “individuals would raise or release the fish” where they did not already exist, Ms. Fellows said, potentially exacerbating the problem; tilapia were originally imported into Latin America for weed and bug control, but commercialization helped the species spread far more widely than intended.
Dr. Kramer is concerned that the marketing of lionfish might increase the number of traps on reefs, which could trap other fish as well. He said spearfishing was the sustainable way to catch lionfish, which are reef dwellers.
Cookbooks do not say much about how to filet an Asian carp, which has an unusual bony structure. And even if one developed a taste for, say, European green crab soup, there is nowhere to buy the main ingredient, though it is plentiful in the sea.
To increase culinary demand, Food and Water Watch has teamed up with the James Beard Foundation and Kerry Heffernan, the chef at the South Gate restaurant in New York City, to devise recipes using the creatures. At a recent tasting, there was Asian carp ceviche and braised lionfish filet in brown butter sauce.
Lionfish, it turns out, looks hideous but tastes great. The group had to hire fishermen to catch animals commonly regarded as pests. Mr. Heffernan said he would consider putting them on his menu and was looking forward to getting some molting European green crabs to try in soft-shell crab recipes.
Last summer, the Nature Conservancy sponsored a lionfish food fair in the Bahamas, featuring lionfish fritters and more. They offered fishermen $11 a pound — about the price of grouper — and got an abundant supply. Lionfish, native to the Indian Ocean and South Pacific, arrived in the Caribbean in the early 1990s and are spreading rapidly; voracious eaters, they even eat juveniles of native fish.
Lionfish, like grouper, can carry ciguatoxin, which causes vomiting and neurological symptoms, so they cannot be taken from water where the microbe that produces the toxin is found. The fish’s venomous spines must be removed before sale, although that is not a serious marketing obstacle.
Mitchell Davis, vice president of the Beard Foundation, said other species had moved from being pariah pests to must-have items on American plates, like dandelion greens for salads.
