Melting glaciers in Antarctica and Greenland may push up global sea levels more than 3 feet by the end of this century, according to a scientific poll of experts that brings a degree of clarity to a murky and controversial slice of climate science.
Such a rise in the seas would displace millions of people from low-lying countries such as Bangladesh, swamp atolls in the Pacific Ocean, cause dikes in Holland to fail, and cost coastal mega-cities from New York to Tokyo billions of dollars for construction of sea walls and other infrastructure to combat the tides.
“The consequences are horrible,” Jonathan Bamber, a glaciologist at the University of Bristol and a co-author of the study published Jan. 6 in the journal Nature Climate Change, told NBC News. …

A crime against humanity specifically aimed at the poor goes virtually unnoticed in our consciousness. It is the privitization of the world's water supply at a time when such actions only seek to deprive millions of this life giving human right. To think that in only 45 years time half of this world will be water scarce is incomprehensible. However, this is where we are heading and if it is allowed to happen people will die.
Privitization, corruption, waste and climate change are now all factors that contribute to the increasing amount of people globally who do not have enough water to live day to day. And as temperatures continue to warm glacial melting will decrease the supply of water to billions of people.
It is heartbreaking to see this affecting the world's poor as it is. For the most part those who live in water scarce areas like Bolivia are not contributing to the conditions that are exacerbating climate change and its effects in these areas. As this film also brings out there is also a social stigma attached to the poor who do not have access to water. It is in essence a caste system set up to deny social access to those who cannot afford water when water should be accessible to all as a human right.

A new movie highlighting the importance of water to our lives and the global crisis we face with ways to address it. It is good to see movies like this being made especially regarding water. We use too much of it (particularly regarding agriculture and energy,) we take it too much for granted and our misconceptions about its availability are being challenged. We are using much more than we can replenish and that exacerbates physical scarcity and non physical scarcity in the form of pollution that makes water unsuitable and unhealthy for human use.
In this age of climate change as well (when we are now seeing the human affect on the hydrologic cycle in connection with extreme weather events such as droughts and floods becoming more frequent and severe) we see moral will colliding with the forces of greed taking advantage of our apathy. We can no longer be secure in thinking we will never be without it and thinking it is a far away obscure crisis. It is here, it is now, and it is about all of us.A new movie highlighting the importance of water to our lives and the global crisis we... more

- So-called water schools, which educate communities on the resource and its links with the environment, gender and climate change, are helping to raise awareness on proper water management in Mexico, at a time of severe drought.
In recent years, projects of this kind have been set up in different parts of Mexico, especially in areas where water is scarce and measures to make water use more efficient are needed.
"We are training people to understand the relationship between water and gender, to influence public policies," Araceli Díaz, the president of the NGO Calmécac, told IPS. "We assess the problems faced by different regions, and then design a water policy agenda."
In 2011, Calmécac – named after the schools attended by the children of the nobility in the Aztec empire - set up a water school in the city of Taxco, in the state of Guerrero, 150 km south of Mexico City. Outreach workers from 12 surrounding municipalities are active in the school.
Because it suffers from chronic water shortages as well as pollution of water sources by gold and silver mining, that southwestern region is in need of special conservation and clean-up measures.
Mexico as a whole is highly vulnerable in terms of water supplies. And the situation has been aggravated by the effects of climate change, which in the medium to long term will threaten the availability of water, with negative impacts on food, agriculture, human health and biodiversity, experts from academia and civil society point out.
Besides the problem of pollution of groundwater, at least 100 of the country’s 653 aquifers are overexploited.
Water schools began to emerge in the decade of the 2000s in several countries of Latin America, due to the critical problems with water. The aim is to educate communities on the value of water, and instruct them in efficient, rational usage techniques. The schools also introduce new habits of water recycling, reuse and treatment.
In addition, they address the link between water and women, since in many communities it is women who are responsible for hauling, storing and distributing water, especially in areas where supplies are scarce.
These locally-based experiences "are important and valuable approaches, because the training and awareness-raising is carried out at a local level. Each local context has a very different set of problems," Edith Kauffer, at the public Centre for Research and Higher Studies in Social Anthropology (CIESAS), told IPS.
"Both local capacity-building and government policies are necessary - they are complementary," said the researcher, who lives in the city of San Cristóbal de las Casas in the southern state of Chiapas.
"The solution does not only lie in the hands of civil society. Governments have a role to play too," she said.
Since 2011, central and northern Mexico have been hit by drought, which has caused significant damage to the agriculture and livestock sectors. And several studies forecast that northern Mexico will continue to suffer water stress in the long term.
In Mexico, 30 percent of households do not have piped water and 15 percent receive water through other means only every three days, according to the National Institute of Statistics and Geography.
One of the water schools operates in the town of Malinalco, population 25,600, in the central state of Mexico, next to the Federal District (the capital). Its work focuses on cleaning up the San Miguel river and improving treatment of sewage or blackwater, and greywater, which is wastewater generated by domestic activities like bathing and washing clothes and dishes.
"We carry out community work with the local population to raise awareness about pollution of bodies of water," Macaira Vera, the head of the water school in Malinalco, told IPS. "The key has been community work, driving it home to local people that if we pollute the water, we are killing ourselves."
The initiative promoted the installation of 125 household biodigesters – containers that convert organic waste into fertiliser and biogas – and the construction of four community plants to treat sewage that previously ended up in the river.
An office that provides advice on water, helping the local population work out specific water treatment and handling problems, was also established.
Each biodigester serves 18 families, and each plant has the capacity to process 1.5 litres of sewage per second. The organisation also carries out monthly analyses of water quality at the community plants and in local wells.
Heavily polluted by raw sewage and fertiliser runoff, the San Miguel river is the hub of the work of the water school, which identified 125 spots where sewage was dumped into the river in 2008.
"We decided to try to get these issues onto the public agenda; we formed online networks to communicate with each other and try to get incorporated into the spaces where these issues are discussed, and decisions are reached," Díaz said.
In its assessments, Calmécac found problems of water availability and supplies, serious pollution, obsolete water distribution infrastructure, and a lack of citizen participation in decision-making.
The organisation is seeking funds to create a wetlands sewage treatment system – constructed wetlands that clean wastewater by filtration, settling, and bacterial decomposition – and to promote eco-techniques like rainwater collection and recycling.
It also foments family gardens, "to get people to change their consumption habits and learn to grow their own food," and hydroponics - a method of growing plants using mineral nutrient solutions instead of soil – Calmécac’s Díaz said.
"The priorities are improving access to piped water, improving water quality, and tackling the enormous lack of sewage treatment," said Kauffer, who is involved in research into the border rivers between Mexico, Guatemala and Belize, along this country’s southern border. "There are practically no rivers that aren’t polluted."

About 55 million years ago, an intense heat wave hit the planet. Earth's surface temperature surged by 9 degrees Fahrenheit (5 degrees Celsius). Then, after a relatively short time, the heat subsided, only to be followed by at least two similar, but smaller heat waves.
Based on chemical clues preserved in rocks, scientists believe a surge of carbon dioxide warmed the planet. But where did all of this greenhouse gas come from?
A team of scientists is proposing that it came from the melting of permafrost, frozen soil packed with organic matter, after cycles in the Earth's orbit warmed up the areas near the poles. The melting released a massive amount of carbon into the atmosphere, keeping reflected sunlight from escaping and causing the heat wave.
Previously, other scientists have theorized that the release of the carbon compound methane trapped in marine sediments — in a form known as methane hydrates — changed the atmosphere. But the study published in the March 5 issue of the journal Nature argues that not enough methane would have been released to account for the magnitude of the warming.
Other theories include a comet impact, extensive fires, or the drying of shallow continental seas — "all these difficult ideas," said study researcher Mark Pagani, a professor at Yale University. None of these explain the sequence of progressively smaller heat waves that followed, Pagani and his colleagues argue.
Examining a rock outcrop near Gubbio, Italy that contains evidence of these heat waves, also known as hyperthermals, the team found they lined up with cycles in the Earth's orbit.
The path of Earth around the sun and the planet's orientation can vary slightly in cycles that last up to 100,000 years. The researchers found that the timing of three large hyperthermals — beginning about 55 million years ago — aligned with periods when the tilt of the Earth's axis was greatest and when the planet's orbit was most eccentric (that is, least circular). [50 Amazing Facts About Earth]
This combination meant the high latitudes — the area closest to the poles — had warmer or longer summers, "with the potential to thaw vast areas of permafrost once a warming threshold is reached," wrote the researchers. The cycle became self-reinforcing, as more carbon entering the atmosphere encouraged more warming, which encouraged more melting and the release of more carbon.
"Then our climate models show if you have permafrost and you warm the temperatures slowly, there is sort of a sweet spot in the model: When you cross it, the whole thing just goes," Pagani said.
Modern discussions of melting permafrost focus on the Arctic. But about 50 million years ago, the world was warmer overall than it is now, and Antarctica was not yet ice-covered, so the researchers argue that the southernmost continent probably had its own large stock of carbon tucked away in the permafrost.
This process produced the successive hyperthermals, the team suspects: After a warming stint lasting some 10,000 years, the carbon from the permafrost would be depleted, resulting in atmospheric carbon dioxide that stuck around for about 200,000 years until natural processes drew it out, cooling the planet down, according to Pagani.
Then, about 1 million years later, the process most like repeated itself, but this time with less permafrost available to melt. This led to a smaller warming pulse, until the hyperthermals ran themselves out, he said.
These ancient hyperthermals are described by the researchers as intense bursts of warming, but nowadays the planet is warming more rapidly. Scientists anticipate that the melting Arctic permafrost is likely to exacerbate things.
"This source of carbon is a large and important source of carbon that has not been released yet; that is just one of those extra things that is waiting around the corner for us," Pagani said.

On July 4, 2010, Joost Notenboom and Michiel Roodenburg set off from Deadhorse, Alaska, on a more-than-18,000-mile journey to the southern tip of Argentina. Their chosen mode of transport: bamboo bicycles. Their mission: to raise awareness of the global water crisis that leaves more than 1 billion people without access to safe drinking water. Eighteen months, 14,000 miles, and 62 flat tires later, we caught up with them just long enough to ask a few questions about their trip so far -- and their plans for when they finish, which, if all goes as planned, will happen in just a few more months. To learn more about their trip, or to support local water projects along their route, check out their website.
Q. What are a couple of Dutchmen doing shouting about water scarcity? Last I checked, there was no dearth of the wet stuff around your corner of the globe.
A. True, true. We actually started getting really interested in water once we finished our university exchange program in Israel a few years ago. (That's also where we met.) Joost was writing his thesis on the issue of water in the Israeli/Palestinian conflict, and that was where we both saw that water is something that people will fight about.
It's also not only a question of scarcity. It's about energy, about food, about climate change, about ecosystems. Water is the basic building block of life. So it's true that back home, we don't have many issues with access to clean water -- everyone has a tap with water coming out -- but we do feel the effects of climate change when the sea levels will start to rise; we do pollute our rivers through industry; and through international trade we increase our virtual water footprint.
What we wanted to do with this trip is learn as much as possible about some of these different issues surrounding water.
Q. Tell the truth, is this not just an excuse to have an epic cycling adventure?
A. Also very true. We cannot say that this is something that we hate doing. It's a lot of fun, and every day is another adventure, literally. But who says you can't do both? Trying to do some good doesn't have to be sacrificial or tiresome; you can have fun while doing it, right?
Visiting these water projects, trying to learn something, doing presentations to share our experiences -- that keeps it very interesting for us. We also get to visit places where tourists normally don't come. This is because we're cycling through some of the tiniest little towns, and on some of the shittiest and most deserted back roads. But it is also because we get asked to come check out remote projects, or talk at universities. This way we get to know so much more about a place and its people than doing a standard Lonely Planet-guided backpack trip.
Q. Have you ever attempted to ghost ride your bikes into a ditch and book a flight home?
A. We've seen a lot of beauty, and we've lived together every day for the past 18 months. We've shared all the ups and the downs, and we both think this is a big reason why we haven't been tempted to book a flight back yet. There's always someone to cheer you up or push you along; doing this kind of thing alone would be something very, very different.
But the most inspiring thing so far has to be the kindness of the people we meet along the way. It's sort of unusual to see two guys on bamboo bikes hauling trailers full of gear. We guess it's instantly clear we're going a long way and people respond to that by offering us a place to stay, advice on travel conditions, a kind word, food, or just a wave from their car as they pass us by. We've had so many encounters with wonderful people that it has completely reinforced our faith in humanity.
Q. What does the water crisis look like? What are some of the images that will stick in your minds?
A. It really is water crises (plural). It has so many faces. It might be a global issue, but every country or region has its own specific consequences and realities.
It's for instance the three little girls pulling a rope together to haul one bucket of water from a well in the tiny little mountain community of Xepatan, in Guatemala. It's hard work, and because these girls have to help their mom doing these chores, this means they cannot go to school. Access to a clean water supply, more than anything else, gives you time. Not having to walk hours a day simply fetching and carrying water means that kids (because it's mostly them that do this) can just be kids, and play and go to school.
It's also the image of not seeing the pink river dolphin in the Amazon Basin. We were invited to go to the Amazon and learn more about this, the largest reservoir of freshwater on our planet, draining more than one-fifth of the world's total river flow. River dolphins are a bellwether species in this aquatic environment, and their health is directly correlated to the health of the forest. Not seeing them means that their environment is most likely in trouble, and we learned that this is mainly due to big hydroelectric projects, pollution [from] gold mining, and deforestation.
Q. Tell us about some of the water projects you've seen or been involved in.
A. There are so many examples of successful projects that made a difference in the lives of those they were intended for. There are solutions for the billion people who don't have access to clean water today; there are solutions for the 2.5 billion who don't have access to basic sanitation. It's a matter of reaching those people and giving them that one little push so they can help themselves. Because -- and we've seen this time and time again -- it's always the local people themselves who want to change their own situation. They get fed up with their kids getting sick, or their crops failing, or their animals dying, and they are clever and proud and entrepreneurial enough to seek out solutions.
We remember going to a fancy university in Costa Rica, and the people there showed us a biodigester they had made which collected all the waste from the student dorms and turned it into energy and clean water. This was their prototype and they were very proud of it. A few months later, in Colombia, we saw the same thing at someone's farm. He had built his own biodigester a few years back because he couldn't afford his electricity bill anymore. He'd just thought of it and it seemed to him like a good idea. Now he collects the sewage from his own house and from his pigs and converts that into power and water. The waste is then used as fertilizer. Sustainable development in action!
Q. What good are you? What have you done to help solve the problem?
A. We can't solve the problem, so we're probably not very good. We're not the fastest cyclists either, nor the strongest; and we're not even the first. We haven't raised the most money, or brought our own water footprint down to zero ... Riding a bicycle from the Arctic to the Antarctic ... is actually sort of easy. But effecting real change is difficult and slow ...
We are raising donations for small, local water projects, and we've deliberately not chosen to raise funds for one big, international NGO. We like those small projects that previously didn't have a chance of reaching out to international private donors, and had to depend solely on public money. So we've supported one pump-building project in Guatemala so far; getting that $20,000 budget financed took a long time. And now we're trying to do the same for another water filtration project in Colombia for which $10,000 has already been raised, and that still needs $4,000.

Charity Water has been doing wonderful things to bring potable water to those who need it most. Over four thousand projects this year alone. In the coming years with climate change and pollution having a greater effect in a world with a growing population, potable water and sanitation will be even more essential to life.
There is no better gift to give than water. To see the smile on the face of a child as they put clean water from a tap to their lips for the first time to drink is unlike any other.
2011 was a year in which we saw more water sources compromised by scarcity, pollution and the effects of climate change (such as drought, evaporation, floods.) This coming year will be no less of a challenge. However, when we work together for a common cause we can do wonders.
Let us make 2012 the year we begin to heal this planet and bring this living liquid to all in our world who need it.
Water Is Life.

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

Every single day, we are getting closer to a horrific global water crisis. This world was blessed with an awesome amount of fresh water, but because of our foolishness it is rapidly disappearing. Rivers, lakes and major underground aquifers all over the globe are drying up, and many of the fresh water sources that we still have available are so incredibly polluted that we simply cannot use them anymore. Without fresh water, we simply cannot function. Just imagine what would happen if the water got cut off in your house and you were not able to go out and buy any. Just think about it. How long would you be able to last? Well, as sources of fresh water all over the globe dry up, we are seeing drought conditions spread. We are starting to see massive "dust storms" in areas where we have never seem them before. Every single year, most of the major deserts around the world are getting bigger and the amount of usable agricultural land in most areas is becoming smaller. Whether you are aware of this or not, the truth is that we are rapidly approaching a breaking point.Every single day, we are getting closer to a horrific global water crisis. This world... more

A severe winter drought is threatening crop production in China, the world's biggest wheat provider, the UN's Food and Agriculture Organisation (FAO) said in an alert issued Tuesday. Substantially below-normal rainfall since October in Northern China has not only put the crop at risk but has also caused shortages in drinking water affecting over 2.57 million people and their livestock, FAO said.
"The ongoing drought is potentially a very serious problem," the Rome-based agency's alert said, adding that the main affected provinces -- around 5.16 million hectres -- represent two-thirds of national wheat production.
On Monday, the FAO warned that floods and heavy rain across southern Africa have damaged thousands of hectares (acres) of farmland, raising fears for food supplies.
World food prices reached their highest level ever recorded in January and are set to keep rising for months, the agency said last week, warning that the hardest-hit countries could face turmoil.
Rising food prices have been cited among the driving forces behind recent popular revolts in north Africa, including the uprising in Egypt and the ouster of Tunisia's president Zine El Abidine Ben Ali after a 23-year rule.
And in its latest survey, FAO said its index which monitors monthly price changes for a variety of staples averaged 231 points in January -- the highest level since records began in 1990.A severe winter drought is threatening crop production in China, the world's... more

Theodore Roosevelt once noted that "civilized people ought to know how to dispose of the sewage in some other way than putting it into the drinking water." But that's what we're still doing every day.
The one-time use of water to disperse human and industrial wastes is an outmoded practice, made obsolete by new technologies and water shortages. Yet it is still common around much of the world. Water enters a city, becomes contaminated with human and industrial wastes, and leaves the city dangerously polluted. Toxic industrial wastes discharged into rivers and lakes or into wells also permeate aquifers, making water -- both surface and underground -- unsafe for drinking.
The current engineering concept for dealing with human waste is to use vast quantities of water to wash it away, preferably into a sewer system, where it may or may not be treated before being discharged into the local river. The "flush and forget" system takes nutrients originating in the soil and typically dumps them into the nearest body of water. Not only are the nutrients lost from agriculture, but the nutrient overload has contributed to the death of many rivers and to the formation of some 405 "dead zones" in ocean coastal regions. This outdated system is expensive and water-intensive, disrupts the nutrient cycle, and can be a major source of disease and death. Worldwide, poor sanitation and personal hygiene claim the lives of some 2 million children per year, a toll that is one-third the size of the 6 million lives claimed by hunger and malnutrition.
Sunita Narain of the Center for Science and Environment in India argues convincingly that a water-based disposal system with sewage treatment facilities is neither environmentally nor economically viable for India. She notes that an Indian family of five, producing 250 liters of excrement in a year and using a water flush toilet, contaminates 150,000 liters of water when washing away its wastes.
As currently designed, India’s sewer system is actually a pathogen-dispersal system. It takes a small quantity of contaminated material and uses it to make vast quantities of water unfit for human use. With this system, Narain says, both "our rivers and our children are dying." India’s government, like that of many developing countries, is hopelessly chasing the goal of universal water-based sewage systems and sewage treatment facilities -- unable to close the huge gap between services needed and provided, but unwilling to admit that it is not an economically viable option.
Fortunately, there is a low-cost alternative: the composting toilet. This is a simple, waterless, odorless toilet linked to a small compost facility and sometimes a separate urine collecting facility. Collected urine can be trucked to nearby farms, much as fertilizer is. The dry composting converts human fecal material into a soil-like humus, which is essentially odorless and is scarcely 10 percent of the original volume. These facilities need to be emptied every year or so, depending on design and size. Vendors periodically collect the humus and market it as a soil supplement, thus ensuring that the nutrients and organic matter return to the soil, reducing the need for energy-intensive fertilizer.
This technology sharply reduces residential water use compared with flush toilets, thus cutting water bills and lowering the energy needed to pump and purify water. As a bonus, it also reduces garbage flow if table wastes are incorporated, eliminates the sewage water disposal problem, and restores the nutrient cycle. The U.S. Environmental Protection Agency now lists several brands of dry compost toilets approved for use. Pioneered in Sweden, these toilets work well under the widely varying conditions in which they are now used, including Swedish apartment buildings, U.S. private residences, and Chinese villages. For many of the 2.5 billion people who lack improved sanitation facilities, composting toilets may be the answer.
Rose George, author of The Big Necessity: The Unmentionable World of Human Waste and Why It Matters, reminds us why the "flush and forget" system is an energy guzzler. One, it takes energy to deliver large quantities of drinking-quality water (up to 30 percent of household water usage is for flushing). Two, it takes energy -- and lots of it -- to operate a sewage treatment facility.
In summary, there are several reasons why the advanced design composting toilets deserve top priority: spreading water shortages, rising energy prices, rising carbon emissions, shrinking phosphate reserves, a growing number of sewage-fed oceanic dead zones, the rising healthcare costs of sewage-dispersed intestinal diseases, and the rising capital costs of "flush and forget" sewage disposal systems.
Once a toilet is separated from the water use system, recycling household water becomes a much simpler process. For cities, the most effective single step to raise water productivity is to adopt a comprehensive water treatment/recycling system, reusing the same water continuously. With this system, which is much simpler if sewage is not included in the waste water, only a small percentage of water is lost to evaporation each time it cycles through. Given the technologies that are available today, it is quite possible to recycle the urban water supply indefinitely, largely removing cities as a claimant on scarce water resources.

Maude Barlow gave this stirring plenary speech, full of hope even in the face of ecological disasters, to the Environmental Grantmakers Association annual retreat in Pacific Grove, California. Barlow, a former UN Senior Water Advisor, is National Chairperson of the Council of Canadians and founder of the Blue Planet Project. Barlow is a contributor to AlterNet's forth-coming book Water Matters: Why We Need to Act Now to Save Our Most Critical Resource.
We all know that the earth and all upon it face a growing crisis. Global climate change is rapidly advancing, melting glaciers, eroding soil, causing freak and increasingly wild storms, and displacing untold millions from rural communities to live in desperate poverty in peri-urban slums. Almost every human victim lives in the global South, in communities not responsible for greenhouse gas emissions. The atmosphere has already warmed up almost a full degree in the last several decades and a new Canadian study reports that we may be on course to add another 6 degrees Celsius (10.8 degrees Fahrenheit) by 2100.
Half the tropical forests in the world – the lungs of our ecosystems – are gone; by 2030, at the current rate of harvest, only 10% will be left standing. Ninety percent of the big fish in the sea are gone, victim to wanton predatory fishing practices. Says a prominent scientist studying their demise “there is no blue frontier left.” Half the world’s wetlands – the kidneys of our ecosystems – were destroyed in the 20th century. Species extinction is taking place at a rate one thousand times greater than before humans existed. According to a Smithsonian scientist, we are headed toward a “biodiversity deficit” in which species and ecosystems will be destroyed at a rate faster than Nature can create new ones.
We are polluting our lakes, rivers and streams to death. Every day, 2 million tons of sewage and industrial and agricultural waste are discharged into the world’s water, the equivalent of the weight of the entire human population of 6.8 billion people. The amount of wastewater produced annually is about six times more water than exists in all the rivers of the world. A comprehensive new global study recently reported that 80% of the world’s rivers are now in peril, affecting 5 billion people on the planet. We are also mining our groundwater far faster than nature can replenish it, sucking it up to grow water-guzzling chemical-fed crops in deserts or to water thirsty cities that dump an astounding 200 trillion gallons of land-based water as waste in the oceans every year. The global mining industry sucks up another 200 trillion gallons, which it leaves behind as poison. Fully one third of global water withdrawals are now used to produce biofuels, enough water to feed the world. A recent global survey of groundwater found that the rate of depletion more than doubled in the last half century. If water was drained as rapidly from the Great Lakes, they would be bone dry in 80 years.
The global water crisis is the greatest ecological and human threat humanity has ever faced. As vast areas of the planet are becoming desert as we suck the remaining waters out of living ecosystems and drain remaining aquifers in India, China, Australia, most of Africa, all of the Middle East, Mexico, Southern Europe, US Southwest and other places. Dirty water is the biggest killer of children; every day more children die of water borne disease than HIV/AIDS, malaria and war together. In the global South, dirty water kills a child every three and a half seconds. And it is getting worse, fast. By 2030, global demand for water will exceed supply by 40%— an astounding figure foretelling of terrible suffering.
Knowing there will not be enough food and water for all in the near future, wealthy countries and global investment, pension and hedge funds are buying up land and water, fields and forests in the global South, creating a new wave of invasive colonialism that will have huge geo-political ramifications. Rich investors have already bought up an amount of land double the size of the United Kingdom in Africa alone.
We Simply Cannot Continue on the Present Path
I do not think it possible to exaggerate the threat to our earth and every living thing upon it. Quite simply we cannot continue on the path that brought us here. Einstein said that problems cannot be solved by the same level of thinking that created them. While mouthing platitudes about caring for the earth, most of our governments are deepening the crisis with new plans for expanded resource exploitation, unregulated free trade deals, more invasive investment, the privatization of absolutely everything and unlimited growth. This model of development is literally killing the planet.

October 15, this Friday is Blog Action Day when thousands of voices across the Internet speak out for one important issue affecting us all. This year the issue is water, and it could not be a more important and crucial issue. From climate change, pollution, to privitization water is quickly becoming a resource we will have less of if we continue to ignore this defining issue of our future and that will leave us without a future. My blog will be participating in this and I hope if you have one you will sign up as well.October 15, this Friday is Blog Action Day when thousands of voices across the... more

It is widely acknowledged that greenhouse gas emission-fueled climate change is having a profound and negative impact on fresh water systems around the world. Warmer weather causes more rapid evaporation of lakes and rivers, reduced snow and ice cover on open water systems, and melting glaciers.
What is less understood is that our collective abuse and displacement of fresh water is also a serious cause of climate change and global warming. If we are to successfully address climate change, it is time to include an analysis of how our abuse of water is an additional factor in the creation of global warming as well as solutions that protect water and watersheds.
There are two major factors. The first is the actual displacement of water from where it is sustaining a healthy ecosystem as well as healthy hydrologic cycles. Because humanity has polluted so much surface water on the planet, we are now mining the groundwater far faster than it can be replaced by nature. New Scientist reports of a “little-heralded crisis” all over Asia as a result of the exponential drilling of groundwater. Water is moved from where nature has put it in watershed and aquifers (where we can access it) to other place where it is used for flood irrigation and food production – where much of it lost to evaporation – or to supply the voracious thirst of mega cities, where it is usually dumped as waste into the ocean.
AUTHOR: Maude Barlow, former senior advisor to the UN on water issues, is co-author of the bestseller Blue Gold (New Press) and chairperson of the Council of Canadians.
Water is also lost to ecosystems through global trade – water used in the in the production of crops or manufactured goods that are then exported (known as virtual trade in water). Over 20% of daily water used for human purpose is exported out of watersheds in this way. Water is also piped across long distances for industry leaving behind parched landscapes.
The second factor is the removal of the vegetation needed for a healthy hydrologic cycle. Urbanization, deforestation and wetland destruction greatly destroy water-retentive landscapes and lead to the loss of precipitation over the affected area.
Slovakian scientist Michal Kravcik and his colleagues explain that the living world influences the climate mainly by regulating the water cycle and the huge energy flows linked to it. Transpiring plants, especially forests, work as a kind of biotic pump, causing humid air to be sucked out of the ocean and transferred to dry land. If the vegetation is removed from the land, this natural system of biosphere regulation is interrupted. Soil erodes, reducing the content of organic material in the ground, thus reducing its ability to hold water. Dry soil from lost vegetation traps solar heat, sharply increasing the local temperature and causing a reduction in precipitation over the affected area. This process also destroys the natural sequestration of carbon in the soil, leading to carbon loss.
Of course, these two factors are deeply related. Just as removing vegetation from an ecosystem will dry up the soil, so too will removing water from an ecosystem mean reduced or non-existent vegetation.
Taken together, these two factors are hastening the desertification of the planet, and intensifying global warming. Even if we successfully address and reverse greenhouse gas emissions and our dependence on fossil fuels, Kravcik says, we will not be able to stop climate change if we do not deal with the impact of our abuse of water on the planet.
Unless we collectively address the crisis of fresh water and our cavalier treatment of the world’s water systems, we will not restore the climate to health.It is widely acknowledged that greenhouse gas emission-fueled climate change is having... more

Six days ago, the Summit on the Summit (SOTS) expedition departed on a mission to conquer the world’s largest freestanding mountain: Mount Kilimanjaro. The 50 mile hike to the 19,340 ft peak led the 14 person team of celebrities, educators, activists including including American actors Emile Hirsch and Jessica Biel, on a trek through high winds, snow, sleet, hail and rain. The expedition, led by Grammy-nominated musician and social activist, Kenna, was made as part of an ambitious effort to raise awareness and promote action to end the global water crisis which affects more than a billion people who lack access to clean water.

FACT: More than 3,500,000 people die every year from water-related diseases.
FACT: Every 15 seconds, a child dies from PREVENTABLE water-borne related illness.
FACT: Nearly a billion people are without SAFE DRINKING WATER.
UNEP, Kenyan government launch fund to save Mau (Kenya Broadcasting Corporation) - The government of Kenya in conjunction with the United Nations Environment Programme (UNEP) has launched a multi million dollar appeal to save the Mau Forests Complex.
The appeal aims at mobilizing resources for the rehabilitation of the Mau, the largest closed-canopy forest ecosystem in Kenya covering over 400,000 hectares - the size of Mount Kenya and the Aberdares combined.
UN Under-Secretary-General and UNEP Executive Director Achim Steiner said: “The Mau Complex is of critical importance for sustaining current and future ecological, social and economic development in Kenya. The rehabilitation of the ecosystem will require substantial resources and political goodwill. UNEP is privileged to work in partnership with the Government of Kenya towards the implementation of this vital project.”
The strategic importance of the Mau Forest lies in the ecosystem services it provides to Kenya and the region, including river flow regulation, flood mitigation, water storage, reduced soil erosion, biodiversity, carbon sequestration, carbon reservoir and micro-climate regulation.
Speaking during the launch Prime Minister lauded Steiner and UNEP for the support provided in the recovery of the water catchment area.

Is it the final curtain for the Fertile Crescent? This summer, as Turkish dams reduce the Tigris and Euphrates rivers to a trickle, farmers abandon their desiccated fields across Iraq and Syria, and efforts to revive the Mesopotamian marshes appear to be abandoned, climate modellers are warning that the current drought is likely to become permanent. The Mesopotamian cradle of civilisation seems to be returning to desert.
Last week, Iraqi ministers called for urgent talks with upstream neighbours Turkey and Syria, after the combination of a second year of drought and dams in those countries cut flow on the Euphrates as it enters Iraq to below 250 cubic metres a second. That is less than a quarter the flow needed to maintain Iraqi agriculture.
Tensions have been growing since May, when the Iraqi parliament refused to approve a new much-needed trade deal with Turkey unless it contained binding clauses on river flows. But Turkey appears in no mood to compromise. In July, it announced the final go-ahead for yet another dam, the Ilisu on the Tigris.Is it the final curtain for the Fertile Crescent?

Hopes that the 10 Nile Basin countries would sign a water-sharing agreement at a meeting in Alexandria to settle one of the planet's most contentious water issues have been dashed — for now at least — after Egypt and Sudan rejected any cuts in their traditional quotas.
But the prospects of a long-term accord on an equitable share-out of the waters of the 3,470-mile Nile, the world's longest river, remain dim, largely because Egypt, the largest user, refuses to surrender its veto powers and its historic rights over the river that has been its lifeblood since time immemorial.
The Nile and its tributaries flow through Egypt, Sudan, Ethiopia, Eritrea, Tanzania, Uganda, Kenya, the Democratic Republic of Congo, Rwanda and Burundi.
The water ministers of these states put off finalizing a treaty for six months when they wrapped up their four-day Alexandria meeting on Tuesday.
In May, the riparian states had drafted a Cooperative Framework Agreement at a summit in the Congo, but Egypt and Sudan refused to sign because it made no mention of their historic claims on Nile water that date back to the colonial era.
Cairo and Khartoum, which do not see eye-to-eye on most things, hailed Tuesday's postponement. "It's a big victory," a senior Sudanese official declared. "They were going to sign the agreement beginning Aug. 1 regardless of Egypt and Sudan."
The dispute over the Nile's life-giving waters has stirred resentment and tension for years now. But now the feuding over water appears to be intensifying.
Some international law experts have gone so far as to suggest that if political and diplomatic efforts fail to settle the issue, the use of military force would be the only option.
Others say it is unlikely that any of these states would resort to such extreme action. But the U.N. Development Program recently voiced concern that conflict over shrinking water resources could trigger "water wars" — as has happened before in the arid Middle East.
Climate change in recent years has reduced rainfall, leading to lower water flows in the Nile and jeopardizing hydraulic projects in several states.
Egypt and neighboring Sudan are the Nile's largest consumers. Egypt, which lies at the end of the river as it flows into the Mediterranean, does not contribute any water to the Nile system.Hopes that the 10 Nile Basin countries would sign a water-sharing agreement at a... more
