Arctic snap will ice Northern states, whipped down by 'bomb cyclone'

(CNN)The ice man cometh. And does so early this year, after a former Pacific typhoon flew up toward the Arctic and rammed the jet stream.

The stream has whipped south, dragging down frigid air from Canada over the northern Plains and Mountain States and the Upper Midwest, according to the National Weather Service.

It is already plunging temperatures below freezing there and will hammer them into the teens and single digits in many places by midweek, even lower in others.

Great Falls, Montana, will shiver at 9 below zero on Tuesday night.

It’s the coldest weather of the season, the weather service said.

Minneapolis could soon get a foot of snow, the service said, with the Minnesota city experiencing below-freezing temperatures that could last for eight days.

Let it snow

The snap is forecast to lay down the first broad layer of wintry snow, flurries, sleet or ice — long before winter starts — from Montana down to Nebraska and over to Wisconsin.

It will accumulate in inches in the northern Rockies, northern Plains and Great Lakes.

People farther south will also shiver. "Much of the nation east of the Rockies is expected to see a major pattern change by the beginning of the work week," the weather service said.

The western Dakotas are also forecast to get significant snow.

Lows will drop to freezing in Kansas City late Monday, then into the 20s a night later. The snap will stop short, leaving much of the Deep South and Southwest in a fall-like warm zone.

Rain is expected to hit Chicago and Milwaukee on Monday and Tuesday, with a few snowflakes mixed in, according to the service on Sunday afternoon.

Residents in the northern United States can thank a whopping tropical cyclone in the Pacific Ocean for the wintry blast.

The remnants of super Typhoon Nuri rolled up north over Alaska’s Aleutian Islands on Friday, kicking off the ripple of Arctic air in the other direction.

Nuri is now the strongest known Northern Pacific cyclone on record, according to the National Weather Service Ocean Prediction Center.

Its remnants plowed into cold air adding violent energy as it went north, similar to what Superstorm Sandy did in the Atlantic two years ago. That earned it the weather moniker "bomb cyclone. More

Drought causes extreme emergency in Haiti

A state of emergency has been declared across northeastern Haiti. This is a country where 78 per cent of the population lives below the poverty level. A severe drought is wiping out sorely needed crops and livestock.

The dry season is due to last at least another month. Even then it will take the area at least another six months to recover when the rains do finally come.

The eight month long drought has caused the loss of two harvest seasons. The hardship is evident in some schools where there is food for students but no water to cook with.

There has been some rain in the area recently but not enough to replenish crops. Indeed the second rainy season began later than usual last year.

Until last November, rainfall had been evenly spread across the crop-producing areas, but that second rain season which usually comes in August, was almost three weeks late. To make matters worse, northeastern Haiti received very little of that rainfall.

Nearby, Jamaica has also been in a state of drought. The government has recently had to dispatch water trucks to the drought-parched west of the island.

The Ministry of Water, Land, Environment and Climate Change says that at least six parishes have been affected, including the one that holds the popular tourist spot of Montego Bay.

There is the possibility of some thundery showers around the northern Caribbean this week, but many places will not see any wet weather. The dry season across the Greater Antilles runs until the end of March. More

Pakistan’s Impending Famine

Thar, Sindh, Pakistan

It’s hard to catch a break in Pakistan.

Extremist violence is widespread, earthquakes and flooding are routine, and polio remains endemic. No nation has a higher infant mortality rate, and only a few have more cases of tuberculosis. Nearly half the country’s 180 million people lack access to safe water, and many Pakistanis have experienced power outages of up to 20 hours per day. Given such stresses, it’s not surprising that up to 16 percent of the country suffers from mental illness.

And now comes the latest scourge: Famine.

In recent days, media reports have revealed that dozens of people—many of them children—have died from malnutrition over the last three months in the bone-dry desert region of Thar, in the southern province of Sindh. And yet things could soon get much worse. A recent UNICEF report, noting that drought has “devastated” crops and livestock and that “hundreds of thousands” of people have fled, warns of a possible “massive humanitarian crisis” in Thar. Ominously, almost 3 million people “risk starvation” across Pakistan.

Many Pakistani press accounts—and numerous Pakistani politicians—depict the Thar tragedy as a catastrophic case of negligence by Sindh’s provincial government. They fault local officials for taking too long to get food assistance to those in need late last year when drought conditions first began to set in. And they single out authorities for failing to transfer sick children in remote areas to better hospitals.

Yet the Thar famine also reflects another type of failure: that of democracy.

In recent years, Pakistan—a country ruled by the military for about half its existence— has made remarkable democratic progress. With successive free elections, civilian rule is firmly in place. Pakistan’s mighty military has mellowed. Constitutional amendments have decentralized power. The Supreme Court is increasingly targeting powerful people and institutions. And private media outlets have rapidly proliferated.

However, there are limits to this progress.

The most commonly cited obstacles to deeper democratization are the military, which continues to exert heavy influence over politics; a lack of pluralism and tolerance, which contributes to the deplorable plight of religious minorities; and the country’s abysmal law enforcement, which enables militants to operate with impunity.

Yet the tragedy in Thar underscores a more insidious and underreported threat to democracy: Astounding manifestations of land inequality.

In Sindh, a paltry 0.05 percent of households hold more than five acres of land (the figure is similar in Punjab, Pakistan’s most populous province). In the nation as a whole, 2 percent of households own nearly 50 percent of land, while 5 percent of agricultural households own nearly two thirds of Pakistan’s farmland.

This means that the majority of the population holds little to no land. Without land, it’s difficult to access food and water (and it’s also difficult to earn a livelihood; landless Pakistanis make up 70 percent of the country’s rural poor). Most Pakistanis must depend on a tiny, wealthy landowning minority for access to these natural resources.

These resources, and the land that holds them, are becoming increasingly precious. According to one alarming estimate, Pakistan loses three acres of good agricultural land every 20 minutes. In Thar, land and natural resources are further imperiled by Islamabad’s plan to tap into the region’s vast coalfields to ease the country’s severe energy crisis. Officials insist there will be no deleterious impacts on local communities, but there’s good reason to fear that such exploitation could cause environmental distress and displacement, and deprive an impoverished region of a critical natural resource. These are very real problems in equally dry and poor Baluchistan, a province long subjected to intensive natural resource extractions by Islamabad and large corporations. Such conditions have helped fuel a long-running separatist insurgency.

In effect, millions of Pakistanis have neither the land to grow food nor the money to buy it. And yet little is done to help them. Landed rural elites—the essence of vested interests in Pakistan—seemingly spend more time blocking critical agricultural reforms (including those that would increase the tax base) than addressing the plight of the landless. They have also been accused of siphoning off irrigation water flows from poor farmers, and of diverting floodwaters away from their crops and into more vulnerable communities. What’s particularly troubling about all this is that these wealthy landowners are often politically connected, or politicians themselves (Sindh’s landed rural elite is a strong base of support for the Pakistan People’s Party, or PPP, which runs the Sindh government).

Consider the strikingly blasé reactions of local officials to current conditions in Thar. Apparently unmoved by (or oblivious to) UNICEF’s warnings of a massive crisis, PPP leaders have described events of recent days as “normal” and “nothing new.” Sindh’s advocate general, speaking Monday at a hearing convened by Pakistan’s Supreme Court, expressed regret, but also appeared to lay the blame on parents for not taking their kids to the hospital.

Perhaps most egregious of all, after federal officials toured affected areas this week, Sindh’s government hosted a lavish buffet lunch featuring fried fish and biryani —“an act of such monumental stupidity and insensitivity,” according to one Pakistani editorial, “that it beggars belief.”

Call this heartlessness, or call it apathy. Many Pakistanis call it feudalism—the embodiment of a system in which imperious landed elites lord over their hapless subjects. One thing you can’t call it, however, is democracy. Yes, it’s an imperfect institution—but surely it doesn’t sanction such vast disparities in land ownership, or the type of leadership that seems unmoved by the humanitarian crises spawned by those disparities.

The takeaway here is that in Thar, people are dying because of deeply entrenched inequalities that make them profoundly food insecure and hyper-vulnerable to calamities—like drought and disease—that more fortunate people elsewhere can withstand and survive.

Ultimately, the dead and dying of Thar—just like slaughtered Shia Muslims, the military’s large political footprint, and state sponsorship of militancy—underscore the fact that despite considerable achievements in recent years, democracy in Pakistan remains a work in progress.

California Exceptional Drought Worsens

I keep hearing from some people how the storms at the end of February and the start of March had to have helped the California drought.

That all the rain that fell in the lowlands and snow in the Sierra had to have had an impact. Right after the storms in my , I was already pointing out that this was not the case. One set of storms does not end a three-year drought. In that post I stated, "The drought in California did not just develop this year, or in the last 12 months, but over the last three years. It is unrealistic to think one series of storms is going to have a huge impact on the long-term drought..."

Now, two weeks later, here is more evidence that the short period of rain and mountain snow had little impact.

Below is a comparison of the Drought Monitor maps for California from Feb. 18 (before the storms) and the one released today.

Over this span of time the area coverage of D4 drought conditions (exceptional) has actually increased substantially from 14.62 percent to 22.37 percent of the area, covering the rich farming area of the Central Coast to the San Joaquin Valley. The D3-4 area (extreme drought) did come down a little from 68.30 to 65.89, mostly in southwestern California.

I have already shown that many reservoirs in central and northern California are still at near-record low levels. The graph below shows the daily Sierra snowpack this year, compared to the previous two years and to normal.

With no substantial rain and snow expected for at least another week, and a round of near-record temperatures likely in the Central Valley and southwestern California coming for this weekend, all of these stats are not going to get any better. In fact, there is a good chance of below- to well below-normal precipitation over the next couple of weeks.

Namibia battles worst drought in decades

Opuwo, Namibia - The Tjikundi family sits around a small fire boiling a tin pot filled with water and maize - the only food that's available this day. A band of children crawl about, chewing on plastic tubing, and chase the visitors with animated curiosity.

The homestead is spectacular in its bareness. Soft, dry sand interrupted only by rocks and boulders fashion a molten envy for a lighter, brighter time. The livestock kraal is empty. So too are the granaries.

Scraggy roosters gawk and peck at the dust with fraught expectation while a domestic cat, at total odds with the environment, purrs and curls around people's ankles.

"This year is very bad because we have lost all our cattle," Mukaokondunga Tjikundi, in her early 20s, told Al Jazeera. "Sometimes the children go to bed with empty stomachs. Sometimes they just drink some water and go to sleep."

Hunger and hardship are recurring themes in Kunene, the northwest province in Namibia, considered the hardest-hit region by a drought many consider the worst in decades.

Almost one million people out of Namibia’s 2.3 million population face moderate to serious levels of food insecurity. The Namibian government in May estimated this year's harvest would yield 42 percent less than 2012.

In Kunene, two years of failed rains have devastated millet and maize plantations, dried up watering holes for livestock, and forced a population to search for precarious water supplies. Animals drink stagnant water in dry riverbeds, while some Namibians dig for water across the province and guard any source found with little wooden fences.

'Catastrophe'

"If people can resort to [drinking] dirty water, more are likely to suffer from water-borne diseases and the health situation is likely to deteriorate for animals and humans," Jack Ndemena, water and sanitation officer with the International Federation of Red Cross and Red Crescent Societies (IFRC), told Al Jazeera.

"There is nothing and if the rains don’t come, it is going to be a catastrophe."

In May, Namibian President Hifikepunye Pohamba was forced to declare a state of emergency and requested $33.7 million in international support to avert a crisis. Recognising the strain across the country, the IFRC and UNICEF launched appeals for $1.2m and $7.4m, respectively.

President Hifikepunye Pohamba has appealed for aid [EPA]

But little aid has arrived.

On September 2, Algeria donated $1m in food aid but the reaction from the rest of the international community has been poor.

Experts say Namibia’s status as a middle-income country hasn’t helped its appeals. Despite its wealth, the country suffers from high levels of income inequality. One-third of the population lives on less than $1 a day, and Namibia ranked 120 out of 187 countries on the 2012 UNDP Human Development Index.

Malnutrition is the second-most common cause of death recorded for children under five, even in non-drought years. And with the onset of this year’s drought, an estimated 109,000 children under five are at risk of acute malnutrition.

"Namibia still does not feed itself, and the middle-income classification comes from livestock, mining and fisheries industries - [this] does not provide an accurate situation on the ground," Cousins Gwanama, head of the Department of Crop Sciences at the University of Namibia in Windhoek, told Al Jazeera.

And it is unlikely the situation is about to get better.

'Confused'

With little rainfall predicted for later this year, farmers have described the drought as among the harshest in a generation. Granaries are empty as few crops were planted last year. With plateaus unsuitable for grazing, many pastoralist farmers have been forced to leave their homes and families and herd their livestock to higher ground with more vegetation, often involving a few days’ walk.

Accustomed to little rainfall, farmers have survived in semi-arid regions of Namibia for decades. But the total absence of precipition has left many perplexed and concerned, their farms lurching towards economic ruin.

"I thought we understood the environment, nature, but we are almost confused and don’t know what to expect," farmer Toivo Ruhozu told Al Jazeera.

"If the government doesn’t help, we will just have to face death." More

Human Influence On Climate Clear, IPCC Report Says

It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. The evidence for this has grown, thanks to more and better observations, an improved understanding of the climate system response and improved climate models.

Warming in the climate system is unequivocal and since 1950 many changes have been observed throughout the climate system that are unprecedented over decades to millennia. Each of the last three decades has been successively warmer at Earth's surface than any preceding decade since 1850, reports the Summary for Policymakers of the IPCC Working Group I assessment report, Climate Change 2013: the Physical Science Basis, approved on Friday by member governments of the IPCC in Stockholm, Sweden.

"Observations of changes in the climate system are based on multiple lines of independent evidence. Our assessment of the science finds that the atmosphere and ocean have warmed, the amount of snow and ice has diminished, the global mean sea level has risen and the concentrations of greenhouse gases have increased," said Qin Dahe, Co-Chair of IPCC Working Group I.

Thomas Stocker, the other Co-Chair of Working Group I said: "Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions."

"Global surface temperature change for the end of the 21st century is projected to be likely to exceed 1.5°C relative to 1850 to 1900 in all but the lowest scenario considered, and likely to exceed 2°C for the two high scenarios," said Co-Chair Thomas Stocker. "Heat waves are very likely to occur more frequently and last longer. As Earth warms, we expect to see currently wet regions receiving more rainfall, and dry regions receiving less, although there will be exceptions," he added.

Projections of climate change are based on a new set of four scenarios of future greenhouse gas concentrations and aerosols, spanning a wide range of possible futures. The Working Group I report assessed global and regional-scale climate change for the early, mid-, and later 21st century.

"As the ocean warms, and glaciers and ice sheets reduce, global mean sea level will continue to rise, but at a faster rate than we have experienced over the past 40 years," said Co-Chair Qin Dahe. The report finds with high confidence that ocean warming dominates the increase in energy stored in the climate system, accounting for more than 90% of the energy accumulated between 1971 and 2010.

Co-Chair Thomas Stocker concluded: "As a result of our past, present and expected future emissions of CO2, we are committed to climate change, and effects will persist for many centuries even if emissions of CO2 stop."

Rajendra Pachauri, Chair of the IPCC, said: "This Working Group I Summary for Policymakers provides important insights into the scientific basis of climate change. It provides a firm foundation for considerations of the impacts of climate change on human and natural systems and ways to meet the challenge of climate change." These are among the aspects assessed in the contributions of Working Group II and Working Group III to be released in March and April 2014. The IPCC Fifth Assessment Report cycle concludes with the publication of its Synthesis Report in October 2014.

"I would like to thank the Co-Chairs of Working Group I and the hundreds of scientists and experts who served as authors and review editors for producing a comprehensive and scientifically robust summary. I also express my thanks to the more than one thousand expert reviewers worldwide for contributing their expertise in preparation of this assessment," said IPCC Chair Pachauri.

Water harvesting helps Kenya's women cope with failing rains

NGURUBANI, Kenya (Thomson Reuters Foundation) – When Rose Wanjiku first moved to her home in Central Kenya province 14 years ago, the region received four months of rain every year. The rains began in April and again in October, and were sufficient for a small-scale farmer such as herself to grow staples like maize and beans to feed her family and sell the surplus at local markets.

Today the Ngurubani area gets only two months of rain a year. Because of the growing scarcity, Wanjiku has resorted to irrigating her crops with water pumped from the Thiba River when rains fail in mid-season. Even though the river is just a stone’s throw away from her house and fields, the water pump means extra expenses for her household.

“Farming has become very expensive for us these days. We hardly make profits,” said her husband Munene. His wife added that the river water cannot be used for household purposes because it is too muddy.

To counter the water shortages, Wanjiku, 45, has begun harvesting rainwater. Her roof is fitted with gutters and through a loan from SMEP, a Kenyan microfinance programme, she has bought a 2,300-litre (600-gallon) water tank to store the harvested water.

Rainwater gathered since April has been sustaining her household until the rains are due to begin again next month.

Wanjiku began making loan payments of 1,000 Kenyan shillings (around $11) a month in February, and aims to clear the loan by November.

The frustrations of poor rainfall also have taken a toll on Margaret Njeri Muthee, 38, another farmer and secretary of the 12-member Wendani Women’s Group, which also counts Wanjiku as a member.

Njeri recalls that when she first moved to Ngurubani 15 years ago, rains were regular and she was able to harvest up to two 90kg bags of beans per acre of land. Today she gets half a bag of beans at most.

“The weather has really changed here – there is a chill I never saw before, destroying our staples,” Njeri said. Because of the unpredictable weather and poor crop yields, Njeri now rears pigs, in addition to chickens and cattle.

“I’m tired of farming maize and beans,” she added.

As a result of increasingly short rainfall, Njeri was spending 400 shillings (nearly $5) every week to pay for a donkey-drawn cart to fetch water from the Thiba River, over a kilometre away from her home. But now she, too, has a water tank, bought on credit from SMEP.

Njeri and Wanjiku are among over 7,000 Kenyan recipients of an ongoing water credit schemeaccessed through microfinance institutions such as SMEP. The scheme enables households to buy tanks to capture and store clean rainwater that runs from rooftops along the gutters.

WIDESPREAD WATER STRESS

UNESCO reports that 17 million of Kenya’s 41 million inhabitants lack access to safe water.

Of the loan recipients, 92 percent are women. According to Patrick Alubbe, East Africa regional director of Water.Org, a nongovernmental organisation, it is the women in households who must spend hours searching for water, and this makes them appreciate the scheme, as it saves them time.

SMEP has given 821 water-related loans so far, with repayment rates of more than 90 percent, according to Fridah Njeru, SMEP’s senior programmes coordinator.

Kenya has 29,000 beneficiaries of water-related loans countrywide, with some funds going to building latrines or fix sewer systems to improve sanitation. The scheme also operates in Uganda, Bangladesh and India.

With a tank to harvest rainwater, Wanjiku says she no longer needs to wait for mud in collected river water to settle at the bottom of her containers so that she can use it at home.

Kenya’s average annual rainfall is 630 mm, which qualities it as a water-scarce country, according to a study published by the U.N. Food and Agriculture Organization. However, astudy by the Southern and Eastern Africa Rainwater Network notes that large groundwater aquifers represents a valuable water resource not directly related to or dependent on rainfall patterns.

Experts are pointing to aquifers as the country’s next important source of water. This comes following the recent discovery of aquifers in the drought-hit Turkana region in Kenya’s north, where rainfall does not exceed 450mm annually.

The aquifers are reported to hold 250 billion cubic metres – enough to supply Kenya’s needs for 70 years at the current rate of consumption of 3 billion cubic metres a year. More

After the Storms, A Different Opinion on Climate Change

Extreme weather may lead people to think more seriously about climate change, according to new research. In the wake of Hurricanes Irene and Sandy, New Jersey residents were more likely to show support for a politician running on a “green” platform, and expressed a greater belief that climate change is caused by human activity.

This research, published in Psychological Science, a journal of the Association for Psychological Science, suggests that traumatic weather events may have the power to shift people’s automatic attitudes — their first instincts — in favor of environmentally sustainable policies.

Though scientists are in near-unilateral agreement that human activity contributes to climate change, the relationship isn’t as clear to many politicians and citizens. This translates into lackluster support for environmental policies, especially when the short-term consequences amount to higher taxes.

“Americans tend to vote more from a self-interested perspective rather than demand that their government affect change,” says lead researcher Laurie Rudman of Rutgers University.

In 2010, Rudman and her colleagues Meghan McLean and Martin Bunzl surveyed over 250 Rutgers undergraduate students, measuring their attitudes toward two politicians, one who favored and another who opposed environmental policies that involve tax increases. The researchers asked the students whether they believed that humans are causing climate change, and they also had the students complete a test intended to reveal their automatic, instinctual preferences toward the politicians.

Though most students said they preferred the green politician, their automatic preferences suggested otherwise. The automatic-attitudes test indicated that the students tended to prefer the politician who did not want to raise taxes to fund environment-friendly policy initiatives.

After Hurricanes Irene and Sandy devastated many areas on the Eastern Seaboard in 2012, Rudman and colleagues wondered whether they would see any differences in students’ attitudes toward environmental policies.

“It seemed likely that what was needed was a change of ‘heart,’” Rudman explains. “Direct, emotional experiences are effective for that.”

In contrast with the first group, students tested in 2012 showed a clear preference for the green politician, even on the automatic attitudes test. And those students who were particularly affected by Hurricane Sandy – experiencing power outages, school disruptions, even damaged or destroyed homes – showed the strongest preference for the green politician.

“Not only was extreme weather persuasive at the automatic level, people were more likely to base their decisions on their gut-feelings in the aftermath of Sandy, compared to before the storm,” Rudman explains.

While they don’t know whether the first group of students would have shown a shift in attitudes after the storms, the researchers believe their findings provide evidence that personal experience is one factor that can influence instinctive attitudes toward environmental policy. If storms do become more prevalent and violent as the climate changes, they argue, more people may demand substantive policy changes. More

Drought Called a Factor in Syria’s Uprising

Two-and-a-half years ago, a group of children in the Syrian city of Dara’a triggered one of the bloodiest conflicts in the 21st century when they painted some anti-government graffiti on a school wall in the ancient farming community.

The children were quickly detained and tortured, leading to widespread protests in the city that were met with harsh repression. The government’s brutal response led to a nationwide revolt that has now stagnated into a bloody stalemate with no end in sight. Dara’a is a mostly agricultural community in a region that has suffered an unrelenting drought since 2001.

Some experts say it’s no accident that Syria’s civil war began there. In 2009, the United Nations and other international agencies found that more than 800,000 Syrian farmers and herdsmen had been forced off their lands because of drought, with many crowding into cities like Dara’a. Additionally, thousands of illegal wells were drilled, drastically lowering the nation’s ground water supply.

The effects of drought and water-mismanagement in the region were highlighted recently by the publication of U.S. National Aeronautic and Space Administration satellite photographs of Syria, Turkey and Iraq. Faced with drought, Syrians crowding these farm towns started drilling deeper for fresh water in the aquifer beneath them. Experts estimated that 60 percent of the aquifer has been lost due to illegal drilling, and a total of 177 million-acre feet of water disappeared, the second-largest aquifer loss in the world.

Satellite images reveal depth of drought

“I actually don’t think the aquifer will recover,” said , a hydrologist and leader of a study of seven years of NASA satellite data that show the Tigris-Euphrates region second only to India in the speed of its groundwater loss. “The Middle East is the dry part of the world and now that climate change is expressing itself very clearly, one of the things that we will see is that the dry parts of the world will get drier,” Famiglietti said. “Think of it as a persistent prolonged drought.” Because of climate change, the Tigris-Euphrates basin and the underground reservoirs of fresh water that once nurtured this fragile desert climate may not be able to sustain future populations in Syria.

It all started in Dara’a

The Syrian uprising was unlike political uprisings in Egypt, Yemen and other Middle East states, all of which started in the major cities. Dara’a was a regional agricultural hub with a pre-war population of 90,000. “Dara’a is the capital of an agricultural province, one of the most significant agricultural areas,” said Syria scholar Ayel Zisser of the Tel Aviv University. Their protests spread from Dara’s at Syria’s southern border to communities north of Aleppo and across the vast al-Jazira plain that stretches from the banks of the Euphrates to the banks of the Tigris. The pattern of the protests followed the rural path of the drought. “Even until today it’s been a peasant revolt isolated to the rural areas,” Zisser said. Assad’s economic reforms focused on global trade that benefitted the urban middle classes, thereby worsening the plight of Syria’s farmers, according to Zisser. The reforms were implemented “at the expense of the population in the rural areas, where they abolished agricultural subsidies,” Zisser said. “The regime turned its back to the rural population and the result was the revolt.” Like other Middle Eastern countries, Syria’s population has increased dramatically in recent years. “This is the first time in history that in less than 30 years, the Middle East doubled its population. It was between 1950 and 1980,” said Arnon Soffer, a demographer and the head of research at the University of Haifa and Israel’s National Defense College. “If that’s not tragic enough, from 1980 to 2010 – another 30 years – this crazy area doubled itself again,” Soffer added. Even before climate change threatened less rainfall in the region, water was a hot-button issue. In 1973, Iraq rushed troops to Syria’s eastern border as upstream, Syria began filling its Tagba Dam with Euphrates water to create Lake Assad.

The real water power in basin is Turkey.

Syria and Iraq depend on the waters of the Euphrates and the Tigris, which flow from southern Turkey, for most of their agricultural irrigation. Farmers on both sides of the border also rely on traditional irrigation techniques that waste water resources. “Turks use most of the water of the Euphrates,” said Bogochan Benli, a water expert who worked in the Aleppo labs of the International Center for Agricultural Research in Dry Areas during the years of the drought. Aleppo and many northern Syrian communities traditionally also depended on the Euphrates for their drinking water, he said. In Turkey, Benli said since the 1970’s the Southeastern Anatolia project has created employment for a poor and arid region of Turkey. It’s the main income-generator for the region and their water policy “will never change.” The project is an ambitious development of 22 dams and 19 hydroelectric power plants to irrigate and provide electrical power in nine Turkish provinces. The centerpiece is the massive Ataturk Dam and hydroelectric power plant that opened in 1990. According Arnon Soffer of Haifa University a few months before the dam was completed, then-Turkish president Turgut Ozal told Syria’s president, Hafez al-Assad, “Now you can wash yourself for the next two months, but I will close the Ataturk Dam and I will dry the Euphrates River.” He said Ozal’s abrupt pronouncement to Hafez Assad was devastating to Syria. “The Euphrates became a wadi, a dry valley,” said Soffer. Assad Dam closed for a month. “The dam was empty and there was no electricity. Even up to today, I could not imagine how they could recover.” Though Turkey and its downstream neighbors have discussed sharing their waters, Turkey has not signed away any rights. With little or no regional cooperation on water issues, experts fear that the turmoil now wrecking Syria could be a prelude to other conflicts in the region. More

While there is still no regional conflict in the region there is a compelling need for an international organization to start a regional conversation on trans-boundary rivers. Rivers, although they may, as in this case originate in Turkey, are a critical element of the global commons, and must be fairly shared by all riverine states. We are no longer in colonial times where for instance Egypt got the lions share of the Nile, leaving very little for Ethiopia. Syria is already in turmoil, Turkey is simmering with protests, Jordan is being blown to and froe and Israel may go off on a tangent at any time. Let us therefore address this issue immediately.

Heat Wave In China

For the entire month of July and the first half of August, eastern China baked in a record-breaking heat wave. Nineteen provinces endured above-normal temperatures.

Shanghai broke its all-time record high three times in as many weeks. The current record—40.8 degrees Celsius (105.4°F)—was set on August 7, 2013. At least 40 people have died during the heat wave, including ten in Shanghai, according to the Xinhua news service.

During a heat wave, ground temperatures soar, particularly in urban areas where there are fewer plants to cool the ground with shade and evapotranspiration. Paved or metallic surfaces can become warm enough to cook food. These images show land surface temperatures as measured by two different satellites.

The image above shows temperature anomalies across China between August 5 and August 12, 2013, as observed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Red areas are warmer than the long-term average for the week, while cooler-than-average temperatures are blue. While much of China was warm during this period, the worst of the heat wave was concentrated near the coast and in Tibet. This weather pattern is tied to a subtropical high-pressure system parked over southern China, according to the China Meteorological Administration.

Though miserable everywhere, the heat wave was likely worst in China’s cities, where manmade surfaces absorb heat during the day and cool slowly at night. As a result, cities are warmer during the day and slower to cool at night, making an extended heat wave more uncomfortable, and more deadly, in a city. The image below shows this “urban heat island” effect in Shanghai.

The image was made with measurements taken on August 13, 2013 by the Thermal Infrared Sensor on the Landsat 8 satellite. The warmest surfaces are yellow, while cooler surfaces are pink. The image shows pockets of very warm areas, particularly downtown, surrounded by cooler suburban areas. The dark purple dots are cold clouds.

Chinese officials have declared a weather emergency, warning residents to limit time outdoors. It is the first time the country has issued a weather warning for heat. China’s National Meteorological Center expected the heat to break sometime after August 15.

Goodbye to All That (Water)

Martha and the Vandellas would have loved it. Metaphorically speaking, the New York Times practically swooned over it. (“An unforgiving heat wave held much of the West in a sweltering embrace over the weekend, tying or breaking temperature records in several cities, grounding flights, sparking forest fires, and contributing to deaths.”)

Colorado River

It was a “deadly” heat wave, a “record” one that, in headlines everywhere, left the West and later the rest of the country “sweltering,” and that was, again in multiple headlines, “scary.” The fire season that accompanied the “blasting,” “blazing” heat had its own set of “record” headlines -- and all of this was increasingly seen, in another set of headlines, as the “new normal” in the West. Given that 2012 had already set a heat record for the continental U.S., that the 10 hottest years on record in this country have all occurred since 1997, and that the East had its own sweltering version of heat that wouldn’t leave town, this should have been beyond arresting.

In response, the nightly primetime news came up with its own convenient set of new terms to describe all this: “extreme” or “severe” heat. Like “extreme" or "severe" weather, these captured the eyeball-gluing sensationalism of our weather moment without having to mention climate change or global warming. Weather, after all, shouldn’t be “politicized.” But if you’re out in the middle of the parching West like TomDispatch regular William deBuys, who recently headed down the Colorado River, certain grim realities about the planet we’re planning to hand over to our children and grandchildren can’t help but come to mind -- along with a feeling, increasingly shared by those in the sweltering cities, that our particular way of life is in the long run unsustainable.

Never Again Enough
Field Notes from a Drying West

Several miles from Phantom Ranch, Grand Canyon, Arizona, April 2013 -- Down here, at the bottom of the continent’s most spectacular canyon, the Colorado River growls past our sandy beach in a wet monotone. Our group of 24 is one week into a 225-mile, 18-day voyage on inflatable rafts from Lees Ferry to Diamond Creek. We settle in for the night. Above us, the canyon walls part like a pair of maloccluded jaws, and moonlight streams between them, bright enough to read by.

One remarkable feature of the modern Colorado, the great whitewater rollercoaster that carved the Grand Canyon, is that it is a tidal river. Before heading for our sleeping bags, we need to retie our six boats to allow for the ebb.

These days, the tides of the Colorado are not lunar but Phoenician. Yes, I’m talking about Phoenix, Arizona. On this April night, when the air conditioners in America’s least sustainable city merely hum, Glen Canyon Dam, immediately upstream from the canyon, will run about 6,500 cubic feet of water through its turbines every second.

Tomorrow, as the sun begins its daily broiling of Phoenix, Scottsdale, Mesa, Tempe, and the rest of central Arizona, the engineers at Glen Canyon will crank the dam’s maw wider until it sucks down 11,000 cubic feet per second (cfs). That boost in flow will enable its hydroelectric generators to deliver “peaking power” to several million air conditioners and cooling plants in Phoenix’s Valley of the Sun. And the flow of the river will therefore nearly double.

It takes time for these dam-controlled tidal pulses to travel downstream. Where we are now, just above Zoroaster Rapid, the river is roughly in phase with the dam: low at night, high in the daytime. Head a few days down the river and it will be the reverse.

By mid-summer, temperatures in Phoenix will routinely soar above 110°F, and power demands will rise to monstrous heights, day and night. The dam will respond: 10,000 cfs will gush through the generators by the light of the moon, 18,000 while an implacable sun rules the sky.

Such are the cycles -- driven by heat, comfort, and human necessity -- of the river at the bottom of the continent’s grandest canyon.

The crucial question for Phoenix, for the Colorado, and for the greater part of the American West is this: How long will the water hold out?

Major Powell’s Main Point

Every trip down the river -- and there are more than 1,000 like ours yearly -- partly reenacts the legendary descent of the Colorado by the one-armed explorer and Civil War veteran John Wesley Powell. The Major, as he preferred to be known, plunged into the Great Unknown with 10 companions in 1869. They started out in four boats from Green River, Wyoming, but one of the men walked out early after nearly drowning in the stretch of whitewater that Powell named Disaster Falls, and three died in the desert after the expedition fractured in its final miles. That left Powell and six others to reach the Mormon settlements on the Virgin River in the vicinity of present-day Las Vegas, Nevada.

Powell’s exploits on the Colorado brought him fame and celebrity, which he parlayed into a career that turned out to be controversial and illustrious in equal measure. As geologist, geographer, and ethnologist, Powell became one of the nation’s most influential scientists. He also excelled as an institution-builder, bureaucrat, political in-fighter, and national scold.

Most famously, and in bold opposition to the boomers and boosters then cheerleading America’s westward migration, he warned that the defining characteristic of western lands was their aridity. Settlement of the West, he wrote, would have to respect the limits aridity imposed.

He was half right.

The subsequent story of the West can indeed be read as an unending duel between society’s thirst and the dryness of the land, but in downtown Phoenix, Las Vegas, or Los Angeles you’d hardly know it.

By the middle years of the twentieth century, western Americans had created a kind of miracle in the desert, successfully conjuring abundance from Powell’s aridity. Thanks to reservoirs large and small, and scores of dams including colossi like Hoover and Glen Canyon, as well as more than 1,000 miles of aqueducts and countless pumps, siphons, tunnels, and diversions, the West has by now been thoroughly re-rivered and re-engineered. It has been given the plumbing system of a giant water-delivery machine, and in the process, its liquid resources have been stretched far beyond anything the Major might have imagined.

Today the Colorado River, the most fully harnessed of the West’s great waterways, provides water to some 40 million people and irrigates nearly 5.5 million acres of farmland. It also touches 22 Indian reservations, seven National Wildlife Reservations, and at least 15 units of the National Park System, including the Grand Canyon.

These achievements come at a cost. The Colorado River no longer flows to the sea, and down here in the bowels of the canyon, its diminishment is everywhere in evidence. In many places, the riverbanks wear a tutu of tamarisk trees along their edge. They have been able to dress up, now that the river, constrained from major flooding, no longer rips their clothes off.

The daily hydroelectric tides gradually wash away the sandbars and beaches that natural floods used to build with the river’s silt and bed load (the sands and gravels that roll along its bottom). Nowadays, nearly all that cargo is trapped in Lake Powell, the enormous reservoir behind Glen Canyon Dam. The water the dam releases is clear and cold (drawn from the depths of the lake), which is just the thing for nonnative trout, but bad news for homegrown chubs and suckers, which evolved, quite literally, in the murk of ages past. Some of the canyon’s native fish species have been extirpated from the canyon; others cling to life by a thread, helped by the protection of the Endangered Species Act. In the last few days, we’ve seen more fisheries biologists along the river and its side-streams than we have tourists.

The Shrinking Cornucopia

In the arid lands of the American West, abundance has a troublesome way of leading back again to scarcity. If you have a lot of something, you find a way to use it up -- at least, that’s the history of the “development” of the Colorado Basin.

Until now, the ever-more-complex water delivery systems of that basin have managed to meet the escalating needs of their users. This is true in part because the states of the Upper Basin (Colorado, Wyoming, Utah, and New Mexico) were slower to develop than their downstream cousins. Under the Colorado River Compact of 1922, the Upper and Lower Basins divided the river with the Upper Basin assuring the Lower of an average of 7.5 million acre-feet (maf) of water per year delivered to Lees Ferry Arizona, the dividing point between the two. The Upper Basin would use the rest. Until recently, however, it left a large share of its water in the river, which California, and secondarily Arizona and Nevada, happily put to use. More
