Even after all that has happened and is happening globally regarding environmental factors and climate change, Americans are still under the impression that we are not vulnerable to that which now effects the developing world. I think this ignorance is what fuels much of the inaction regarding water issues and climate change in America. It needs to change. Now.
All reservoirs along the Colorado River might dry up by mid-century as the West warms, a new study finds. The probability of such a severe shortage by then runs as high as one-in-two, unless current water-management practices change, the researchers report.
The study's coauthors looked at the effects of a range of reductions in Colorado River stream flow on future reservoir levels and at the implications of different management strategies.
Even under the harshest drying caused by climate change, the large storage capacity of reservoirs on the Colorado might help sustain water supply for a few decades. However, new water management approaches are critical to minimize the chances of fully depleting reservoir storage by mid-century.
"This study, along with others that predict future flow reductions in the Colorado River Basin, suggests that water managers should begin to re-think current water management practices during the next few years, before the more serious effects of climate change appear," says lead study author Balaji Rajagopalan of the University of Colorado in Boulder (CU-Boulder).
The findings by Rajagopalan and his colleagues have been accepted by the journal Water Resources Research, published by the American Geophysical Union (AGU).
The Colorado River system is enduring its 10th year of a drought. Fortunately, the river system entered the drought in 2000, with the reservoirs at approximately 95 percent of capacity. The reservoir system is currently at 59 percent of capacity, about the same as this time last year, says Rajagopalan. Roughly 30 million people depend on the Colorado River for drinking and irrigation water.
The research team examined the future vulnerability of the system to water supply variability coupled with projected changes in water demand. They found that through 2026, the risk of fully depleting reservoir storage in any given year remains below 10 percent under any scenario of climate fluctuation or management alternative. During this period, the reservoir storage could even recover from its current low level, according to the researchers.
But if climate change results in a 10 percent reduction in the Colorado River's average stream flow as some recent studies predict, the chances of fully depleting reservoir storage will exceed 25 percent by 2057, according to the study. If climate change results in a 20 percent flow reduction, the chances of fully depleting reservoir storage will exceed one in two by 2057, Rajagopalan says.
"On average, drying caused by climate change would increase the risk of fully depleting reservoir storage by nearly ten times more than the risk we expect from population pressures alone," Rajagopalan says.
"By mid-century this risk translates into a 50 percent chance in any given year of empty reservoirs, an enormous risk and huge water management challenge," he says.
The river hosts more than a dozen dams along its 2,330-kilometer (1,450-mile) journey from Colorado's Rocky Mountains to the Gulf of California.

St. Thomas which was a city covered by Lake Mead due to Hoover Dam construction is now exposed due to recession of water levels. To some that may seem like justice because of what was done to St. Thomas originally because of the dam construction, but now this lake which is one of the largest has millions of people dependent on it for water. So now, those in this area who once lost all due to the water coming in may well see that again because of the opposite effect. This is a stark example of what population increases and climate change combined with waste can lead to. It should be a lesson to us all.
The defining moment of the 21st Century will not be securing another planet for us to live on. It will be how we meet this challenge on Earth. Can we get beyond the backbiting to keeping our eye on the prize? Or will our continued political, social, and religious differences keep us from the moral imperative? This is no joke. Water is becoming a scarcer resource for many people around the globe through waste, pollution, climate change, and privitization. By our hand.
Humans cannot live without water. So it should follow logically that if humans cannot live without water and potable freshwater is becoming scarcer that this would certainly be a crisis that is a matter of life and death. And yet, this issue hardly gets the attention it deserves.
Please look at these pictures at the link provided and realize that this is not about what is causing global warming/climate change and the petty political grudges that keep that debate from taking us to the necessary solutions to save this planet for ourselves and future generations. This is about seeing that future and visualizing what you know in your heart it should look like... and then making it happen.
Yes! Let's keep that going! Bottled water is one of the biggest scams ever perpetrated on the planet! And then we need to start working on plastic bottles in general that waste fuel, create carbon emissions that contribute to climate change, and cause massive plastic garbage swirls as can be found in the Great Pacific Garbage Patch.
It is time to assess just what we are doing to this planet and realize our potential to change it!
Excerpt:
An Australian town was set to ban bottled water on Wednesday over concerns about its environmental impact, in what is believed to be a world first. Bundanoon, a picturesque rural town with a population of just 2,000, was expected to vote heavily in favour of the move with a show of hands at a public meeting later. "At the moment we've got a lot of community support behind it. We're confident the town is going to back it," said activist John Dee.
"We believe Bundanoon is the world's first town that has got its retailers to ban bottled water. We haven't found it anywhere else." Local opinion was incensed when beverage company Norlex Holdings announced plans to tap an underground reservoir in the town, truck the water up to Sydney and then send it back in bottled form.
"The company has been looking to extract water locally, bottle it in Sydney and bring it back here to sell it again," said Dee. "It made people look at the environmental impact of bottled water and the community has been quite vocal about it."
Dee, whose Do Something group was instrumental in a plastic bags ban in Coles Bay, Tasmania, said he hoped the ban would make people think twice about buying bottled water. "It's possible it will extend to other places. The main idea is to get people thinking about their usage of bottled water -- we're spending about half a billion dollars on it here in Australia," he said.
'Palestinian President Mahmoud Abbas said Israel must address the vital issue of water in the West Bank if meaningful peace talks are to take place. Israel's leaders said nothing, but Abbas had touched on one of the most sensitive issues in the seemingly endless negotiations, which have been in abeyance for the last few years, and one on which any expectation of a comprehensive settlement will probably ultimately rest.Israel's unilateral control over rivers and aquifers meant scarce water resources were not being shared equitably "as required by international law," he declared. "It is with dismay that I see 9,000 Israeli settlers in the Jordan Valley utilize one-quarter of the water that the entire Palestinian population in the West Bank utilizes," he told the World War Forum in Istanbul.
In the largely arid Middle East, water is more valuable than oil and has been a source of conflict since time immemorial. As the world's resources, from oil to timber and minerals, dwindle, the prospect of more water wars in the Middle East in the decades ahead increase with each passing day. The crisis is deepened by rapidly expanding populations across the Arab world. This, coupled with industrial growth and a relentless drive for food self-sufficiency, is draining water supplies faster than they can be replenished. Global warming accelerates the damage.
Climate experts warn that one-third of the Earth's surface may be at risk of extreme drought by the end of the century, triggering mass migrations of "environmental refugees." Many of those will be in the Middle East and North Africa. The region has been hit by a severe drought for the last five years, making the water issue all that more critical, aggravating a dispute between the Israelis, whose own water resources are dwindling, and the Palestinians, who sit on a major aquifer under the West Bank that Israel covets as much as its ever-expanding archipelago of settlements.Israel views the water from the West Bank -- as it did the water it siphoned off from the Litani River in Lebanon during its 1978-2000 occupation of that country's southern zone -- as vital to its national security. The Palestinians will not be able to sustain a viable independent state without water. _________________ How hard is this for Israel or any oher country to understand? Water is the lynchpin to peace.
'A team of NOAA-supported scientists from the Louisiana Universities Marine Consortium, Louisiana State University, and the University of Michigan is forecasting that the "dead zone" off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be one of the largest on record. The dead zone is an area in the Gulf of Mexico where seasonal oxygen levels drop too low to support most life in bottom and near-bottom waters.
Scientists are predicting the area could measure between 7,450 and 8,456 square miles, or an area roughly the size of New Jersey. However, additional flooding of the Mississippi River since May may result in a larger dead zone. The largest one on record occurred in 2002, measuring 8,484 square miles.
Dead zones are caused by nutrient runoff, principally from agricultural activity, which stimulates an overgrowth of algae that sinks, decomposes, and consumes most of the life-giving oxygen supply in the water.
The dead zone size was predicted after researchers observed large amounts of nitrogen feeding into the Gulf from the Mississippi and Atchafalaya Rivers. The rivers experienced heavy water flows in April and May that were 11 percent above average.
"The high water volume flows coupled with nearly triple the nitrogen concentrations in these rivers over the past 50 years from human activities has led to a dramatic increase in the size of the dead zone," said Gene Turner, Ph.D., a lead forecast modeler from Louisiana State University.
This forecast helps coastal managers, policy makers, and the public better understand and combat the sources of the dead zones. For example, the models that generate this forecast have been used to determine nutrient reduction targets required to reduce the size of the dead zone.
This hypoxic, or low-to-no oxygen area, is of particular concern because it threatens valuable commercial and recreational Gulf fisheries by destroying critical habitat."
End of excerpt _________ It isn't enough that we are killing the land and air with toxic waste and poisoning our food with an overuse of pesticides and herbicides... we are now literally sucking the life out of our water. Hypoxia is the phenomenon we now see in the Gulf Of Mexico, which is a lack of oxugen in the water whicha lso effects marinlife and which also effects many bodies of water worldwide.
And we, humans, are doing it. In our zeal to make lots of money that we think we can actually enjoy in a poisoned world where our health and the sustainability of our planet is threatened, we have lost touch with our true purpose as stewards of this planet. Pesticides, herbicides, CAFOS, climate change, and the relentless lobbying of the brokers of these poisons to politicians are all part of the vicious circle we now are part of.
Somewhat good news considering the drought Iraq is currently in. Although, considering they are also growing Monsanto seeds, I don't know how truly prosperous Iraqi farmers will be now.
