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

Whether We Engage or Do Nothing... This Changes Everything

The following is an excerpt taken from the introduction of Naomi Klein's newly published book, This Changes Everything: Capitalism vs. the Climate, and appears at Common Dreams with permission from the book's publisher Simon & Shuster. All rights reserved.

“Most projections of climate change presume that future changes—greenhouse gas emissions, temperature increases and effects such as sea level rise—will happen incrementally. A given amount of emission will lead to a given amount of temperature increase that will lead to a given amount of smooth incremental sea level rise. However, the geological record for the climate reflects instances where a relatively small change in one element of climate led to abrupt changes in the system as a whole. In other words, pushing global temperatures past certain thresholds could trigger abrupt, unpredictable and potentially irreversible changes that have massively disruptive and large-scale impacts. At that point, even if we do not add any additional CO2 to the atmosphere, potentially unstoppable processes are set in motion. We can think of this as sudden climate brake and steering failure where the problem and its consequences are no longer something we can control.” —Report by the American Association for the Advancement of Science, the world’s largest general scientific society, 2014

“I love that smell of the emissions.” — Sarah Palin, 2011

I denied climate change for longer than I care to admit. I knew it was happening, sure. Not like Donald Trump and the Tea Partiers going on about how the continued existence of winter proves it’s all a hoax. But I stayed pretty hazy on the details and only skimmed most of the news stories, especially the really scary ones. I told myself the science was too complicated and that the environmentalists were dealing with it. And I continued to behave as if there was nothing wrong with the shiny card in my wallet attesting to my “elite” frequent flyer status

Climate change is... hard to keep it in your head for very long. We engage in this odd form of on-again-off-again ecological amnesia for perfectly rational reasons. We deny because we fear that letting in the full reality of this crisis will change everything. And we are right."

A great many of us engage in this kind of climate change denial. We look for a split second and then we look away. Or we look but then turn it into a joke (“more signs of the Apocalypse!”). Which is another way of looking away.

Or we look but tell ourselves comforting stories about how humans are clever and will come up with a technological miracle that will safely suck the carbon out of the skies or magically turn down the heat of the sun. Which, I was to discover while researching this book, is yet another way of looking away.

"Climate change is... hard to keep it in your head for very long. We engage in this odd form of on-again-off-again ecological amnesia for perfectly rational reasons. We deny because we fear that letting in the full reality of this crisis will change everything. And we are right."

Or we look but try to be hyper-rational about it (“dollar for dollar it’s more efficient to focus on economic development than climate change, since wealth is the best protection from weather extremes”)—as if having a few more dollars will make much difference when your city is underwater. Which is a way of looking away if you happen to be a policy wonk. Or we look but tell ourselves we are too busy to care about something so distant and abstract—even though we saw the water in the subways in New York City, and the people on their rooftops in New Orleans, and know that no one is safe, the most vulnerable least of all. And though perfectly understandable, this too is a way of looking away.

Or we look but tell ourselves that all we can do is focus on ourselves. Meditate and shop at farmers’ markets and stop driving—but forget trying to actually change the systems that are making the crisis inevitable because that’s too much “bad energy” and it will never work. And at first it may appear as if we are looking, because many of these lifestyle changes are indeed part of the solution, but we still have one eye tightly shut.

Or maybe we do look—really look—but then, inevitably, we seem to forget. Remember and then forget again. Climate change is like that; it’s hard to keep it in your head for very long. We engage in this odd form of on-again-off-again ecological amnesia for perfectly rational reasons. We deny because we fear that letting in the full reality of this crisis will change everything. And we are right.

We know that if we continue on our current path of allowing emissions to rise year after year, climate change will change everything about our world. Major cities will very likely drown, ancient cultures will be swallowed by the seas, and there is a very high chance that our children will spend a great deal of their lives fleeing and recovering from vicious storms and extreme droughts. And we don’t have to do anything to bring about this future. All we have to do is nothing. Just continue to do what we are doing now, whether it’s counting on a techno-fix or tending to our gardens or telling ourselves we’re unfortunately too busy to deal with it.

All we have to do is not react as if this is a full-blown crisis. All we have to do is keep on denying how frightened we actually are. And then, bit by bit, we will have arrived at the place we most fear, the thing from which we have been averting our eyes. No additional effort required.

There are ways of preventing this grim future, or at least making it a lot less dire. But the catch is that these also involve changing everything. For us high consumers, it involves changing how we live, how our economies function, even the stories we tell about our place on earth. The good news is that many of these changes are distinctly un-catastrophic. Many are downright exciting. But I didn’t discover this for a long while.

"All we have to do is not react as if this is a full-blown crisis. All we have to do is keep on denying how frightened we actually are. And then, bit by bit, we will have arrived at the place we most fear, the thing from which we have been averting our eyes. No additional effort required."

I remember the precise moment when I stopped averting my eyes to the reality of climate change, or at least when I first allowed my eyes to rest there for a good while. It was in Geneva, in April 2009, and I was meeting with Bolivia’s ambassador to the World Trade Organization (WTO), who was then a surprisingly young woman named Angélica Navarro Llanos. Bolivia being a poor country with a small international budget, Navarro Llanos had recently taken on the climate portfolio in addition to her trade responsibilities. Over lunch in an empty Chinese restaurant, she explained to me (using chopsticks as props to make a graph of the global emission trajectory) that she saw climate change both as a terrible threat to her people—but also an opportunity.

A threat for the obvious reasons: Bolivia is extraordinarily dependent on glaciers for its drinking and irrigation water and those white-capped mountains that tower over its capital were turning gray and brown at an alarming rate. The opportunity, Navarro Llanos said, was that since countries like hers had done almost nothing to send emissions soaring, they were in a position to declare themselves “climate creditors,” owed money and technology support from the large emitters to defray the hefty costs of coping with more climate-related disasters, as well as to help them develop on a green energy path.

She had recently given a speech at a United Nations climate conference in which she laid out the case for these kinds of wealth transfers, and she gave me a copy. “Millions of people,” it read, “in small islands, least developed countries, landlocked countries as well as vulnerable communities in Brazil, India and China, and all around the world—are suffering from the effects of a problem to which they did not contribute. . . . If we are to curb emissions in the next decade, we need a massive mobilization larger than any in history. We need a Marshall Plan for the Earth. This plan must mobilize financing and technology transfer on scales never seen before. It must get technology onto the ground in every country to ensure we reduce emissions while raising people’s quality of life. We have only a decade.” More

Mega dry spell Spain's worst in 150 years

Parts of Spain are currently suffering through their most intense dry spell in a century and a half with Valencia and Alicante among the worst affected regions. Future predictions are not too rosy either, meteorologists warn.

The last eight months have been brutally dry for large swathes of southern and eastern Spain.

While huge storms buffeted Spain's Atlantic coasts and the Canary Islands during the winter and spring, Valencia and Alicante, as well as areas including Murcia, parts of Albacete province, and the Andalusian provinces of Jaén, Almería, Cadíz and Málaga have all been starved of rain.

In the last 150 years, there has never been "such a long and intense drought", according to the country's meteorological agency Aemet.

Indeed there are parts of the country where during "the second worst period of drought on record there was twice as much rain as now", meteorologist José Antonio Maldonado told Spanish free daily 20 minutos.

Rainfall levels in many areas have been less than half of those seen from 1971 to 2000, while some places have seen less than 25 percent of those levels.

Most dams are still at somewhere between 74 percent and 90 percent of capacity thanks to rains from earlier years, but some farmers are already struggling to water their crops, or have gone out of business.

Spain is also facing an uncertain water future: a 2013 study by the Spanish National Research Council (CSIC) looking at the period from 1945 to 2005 found the country's droughts were becoming more intense and more regular. 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.

    Farmers worldwide suffer as extreme weather wreaks food havoc

    To address the crisis, farm ministers from around the world are gathering in Berlin Saturday to discuss climate change and food production.

    BOSTON — Volatile weather around the world is taking farmers on a wild ride. Too much rain in northern China damaged crops in May, three years after too little rain turned the world’s second-biggest corn producer into a net importer of the grain. Dry weather in the U.S. will cut beef output from the world’s biggest producer to the lowest level since 1994, following 2013’s bumper corn crop, which pushed America’s inventory up 30 percent. British farmers couldn’t plant in muddy fields after the second-wettest year on record in 2012 dented the nation’s wheat production.

    “Extreme weather events are a massive risk to agriculture,” said Peter Kendall, president of the British National Farmers Union, who raises 3,953 acres of grain crops in Bedfordshire, England. “Farmers can adapt to gradual temperature increases, but extreme weather events have the potential to completely undermine production. It could be drought, it could be too much rain, it could be extreme heat at the wrong time. It’s the extreme that does the damage.”

    Farm ministers from around the world are gathering in Berlin Saturday to discuss climate change and food production at an annual agricultural forum, with a joint statement planned after the meeting.

    Fast-changing weather patterns, such as the invasion of Arctic air that pushed the mercury in New York from an unseasonably warm 55 degrees Fahrenheit on Jan. 6 to a record low of 4 the next day, will only become more commonplace, according to the New York-based Insurance Information Institute. While the world produces enough to provide its 7 billion people with roughly 2,700 calories daily, and hunger across the globe is declining, one in eight people still don’t get enough to eat, some of which can be blamed on drought, the United Nations said.

    “There’s no question, while there’s variability and volatility from year to year, the number and the cost of catastrophic weather events is on the rise, not just in the U.S., but on a global scale,” said Robert Hartwig, an economist and president of the insurance institute. “It’s all but certain that the size and the magnitude and the frequency of disaster losses in the future is going to be larger than what we see today.”

    The number of weather events and earthquakes resulting in insured losses climbed last year to 880, 40 percent higher than the average of the last 30 years, according to Munich Re, the world’s largest reinsurer.

    Research points to a culprit: an increase in greenhouse gases, generated by human activity, that are forcing global temperatures upward, said Thomas Peterson, principal scientist at the U.S. National Climatic Data Center in Asheville, N.C. The warmer the air the more water it can hold, he said.

    “What we’re finding worldwide is that heavy precipitation is increasing,” Peterson said.

    Flood waters in Passau, Germany, in May and June reached the highest level since 1501, Munich Re said. That was the year Michelangelo first put a chisel to the block of marble that would become his sculpture of David. High water did $15.2 billion in damage in parts of Central and Eastern Europe, according to Munich Re.

    A July hailstorm in Reutlingen, Germany, led to $3.7 billion in insured losses, according to Munich Re. Hailstones the size of babies’ fists cracked the windshield of Marco Kaschuba’s Peugeot.

    “Two minutes before the storm started you could already hear a very loud noise,” said Kaschuba, a 33-year-old photographer. “That was from hailstones hitting the ground in the distance and coming closer.”

    In 2012, Britain had its second-highest rainfall going back to 1910, according to Britain’s meteorology office. England and Wales had its third-wettest year since 1766. More

    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.

    The Summary for Policymakers of the Working Group I contribution to the IPCC Fifth Assessment Report (WGI AR5) is available at www.climatechange2013.org or www.ipcc.ch.

    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

    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.
