Mom & I went for a lovely morning #NatureWalk at #ElkLake after my denturist appointment.
We only saw 2 other people on the trail. We had our morning tea, at the lake.
💧 the #seawater#greenhouse is a really cool idea, literally. It's a way of using evaporating seawater to cool and humidify crops 🌱, which can drastically reduce the amount of fresh #water needed to support the #crop in a desert #climate.
As #climatechange and #freshwater scarcity increasingly challenges crop survival over the coming decades, carbon neutral seawater greenhouses will become much more common.
So when I tell y'all I've got to go get my son at MTU in Houghton, MI, it should be no surprise that I'll drive 8 hours - one way - and still be in Michigan. (Houghton is that 2nd to last stop at the very northern part of the upper peninsula on that map) https://en.osm.town/@TerribleMaps/112151215602573413
New analysis shows that the global #freshwater cycle has shifted far beyond pre-industrial conditions
An analysis of freshwater resources across the globe shows that the updated planetary boundary for freshwater change was surpassed by the mid-20th century. In other words, for the past century, humans have been pushing the Earth's freshwater system far beyond the stable conditions that prevailed before industrialization.
"Shifts in the hydrologic cycle are creating many of the most urgent needs for adaptation. Driven by climate change, these shifts threaten the availability of #freshwater, impoverishment of biodiversity, reduced food production, and direct and indirect impacts on human health. Traditional approaches to managing hydrologic variability are failing..."
Arguably Australia's most precious asset.

#Bitcoin’s growing #water footprint
Each Bitcoin transaction uses 4,200 gallons of water — enough to fill a swimming pool — and could potentially cause #freshwater shortages. A data scientist at DNB and a researcher for VU Amsterdam, stressed water consumption has increased over the years. He also calculated computational process behind Bitcoin uses 8.6 to 35.1 billion liters of water annually in the #USA or roughly one swimming pool's worth of water per transaction. https://www.cell.com/cell-reports-sustainability/fulltext/S2949-7906(23)00004-6#secsectitle0010

"When #Maine lawmakers tried to rein in large-scale access to the state’s #freshwater this year, the effort initially gained momentum. The state had just emerged from #drought, and many Mainers were sympathetic to protecting their snow-fed #lakes and #streams.
“BlueTriton isn’t a household name, but its products are. Americans today buy more bottled water than any other packaged drink, and BlueTriton owns many of the nation’s biggest brands, including Poland Spring, named after a natural spring in Maine that ran dry decades ago.
“Maine’s bill threatened BlueTriton’s access to the #groundwater it bottles and sells. The legislation had already gotten a majority vote on the committee and was headed toward the full Legislature, when a lobbyist for BlueTriton proposed an amendment that would gut the entire bill.
“'Strike everything,' starts the proposed amendment, which was written in a Word document that contained a digital signature showing that it had been created by Elizabeth M. Frazier, who represents BlueTriton and is one of the most influential #lobbyists in Maine. The document was e-mailed by Ms. Frazier to lawmakers in the days after the committee vote.
“After BlueTriton’s intervention, the committee pulled the bill back. The company’s actions, which haven’t previously been reported, were described to The New York Times by three state legislators. The Times also reviewed several of the e-mails sent by Ms. Frazier as well as the Word document.
“'We couldn’t believe it. Their amendment strikes the entire bill,' said Christopher Kessler, a Democratic state representative who represents South Portland and a committee member who voted to advance the bill. 'Because all this happened behind closed doors, the public doesn’t know that Poland Spring stalled the process.'
“Bottlers have faced increasing scrutiny for the millions of throwaway #plastic bottles they produce, the marketing message that their products are safer or healthier than tap water, and for a business model in which they buy freshwater, often at low cost, only to sell it back to the public at much higher prices.
“And while the bottled-water business doesn’t use nearly as much groundwater as the nation’s thirstiest industries, like agriculture, the pressure on bottlers is building as awareness grows of the stress that intensive pumping can place on local water supplies. A Times investigation this year revealed that many of the aquifers that supply 90% of the nation’s water systems are being severely depleted as overuse and #GlobalWarming transform fragile #ecosystems.
“BlueTriton has been caught up in issues of local opposition and water use, and not only in Maine. The company also is fighting for access to water sources in numerous states, including #Michigan, #Colorado and others.
“In response to detailed questions, BlueTriton on Monday pointed The Times to a new page on its corporate website. 'After thoughtful consideration, BlueTriton opposes the proposed legislation,' the page says, because the bill 'would make it unaffordable for any large-scale water purchaser, including Poland Spring, to invest in infrastructure and operations.'
“Ms. Frazier didn’t respond to detailed questions.
“Groundwater use is regulated by states, not the federal government, which means there is little national coordination, monitoring or management of a vital natural resource. Maine’s bill seeks, among other things, to put a seven-year limit on contracts for large-scale freshwater pumping by corporations that ship water out of Maine, and to make the deals subject to local approval. That would block BlueTriton’s current efforts to lock in contracts up to 45 years long for pumping water.
“'We couldn’t believe it,' State Representative Christopher Kessler said of the lobbying effort.
“Industries and other interest groups routinely try to influence lawmaking, and there has been no suggestion that Ms. Frazier violated any rules. But it seemed 'unusual procedurally' for a corporation to propose rewriting an entire bill after it had already advanced within the Legislature, said Anthony Moffa, associate professor at the University of Maine School of Law.
“State senator Mark Lawrence, a Democrat who heads the committee considering the bill, said the committee would consider amendments proposed by any interested person or party. In Maine, 'a lot of the legislation that’s proposed is written by lobbyists, companies, different people like that,' he said.
“Mr. Lawrence also said that, at the same time the amendment was proposed, several members had begun to express fresh concerns that the State Legislature would be setting overly stringent curbs on contracts.
“BlueTriton finds itself pitted against local water boards, environmentalists and other groups across the country.
“In Colorado, environmental groups have been battling a 10-year contract that BlueTriton renewed with a semi-arid county to pump water from the Upper Arkansas River Basin, a region affected by historic drought.
“In #California, BlueTriton has publicly criticized and vowed to fight a cease-and-desist order issued by the state’s water board to stop diverting millions of gallons of water from a spring in San Bernardino County.
“In Michigan, lawmakers have proposed legislation that would close a loophole that enables BlueTriton and other commercial water users to pump water from the protected Great Lakes watershed. Known as the 'bottled-water loophole,' it allows for water to be used this way if it’s in containers that are 5.7 gallons or less.
“On its new corporate page, BlueTriton said 'there is no evidence of adverse impacts to the aquifer' in Colorado, and that California’s ruling 'negatively impacts every water agency and farmer in California that relies on groundwater, and in doing so, indirectly harms every Californian.'
“BlueTriton is a major presence in Maine, drawing water from eight locations around the state. It is currently trying to lock in a new contract of up to 45 years to pump water in Lincoln a former mill town.
“That would be BlueTriton’s second decades-long contract in the state, the kind of deals that would run afoul of the State Legislature’s proposed 7-year cap. The company’s pursuit of these deals, and the uncertainties of how climate change may affect Maine’s water supplies in the future, is what inspired the legislation, said Margaret M. O’Neil, the Democratic state legislator who introduced the bill.
“'We’re seeing our communities get locked into these contracts that are going to last, basically, the rest of my lifetime,' which is too risky, she said, considering climate uncertainties.
“In 2016-17 and in 2020-22, Maine experienced significant drought, followed by wet years. The state has also started seeing what scientists call 'snow drought.' As winters warm because of #ClimateChange, #snowpack and groundwater recharge can dwindle.
“John Mullaney, a hydrologist with the USGS's New England Water Science Center, said that a warming climate meant Maine was likely to experience more variability, with stronger rains but also worsening drought. 'The question is, what will we be able to do in 50 years,' he said. 'There might be changes that need to be made, including reducing groundwater extraction.'
“Industry groups emphasize that Maine still has ample groundwater and that bottled water accounts for only a small portion of its use compared to practices like irrigation. They also stress bottled water’s value in emergencies when drinking water is disrupted.
“And in Maine, BlueTriton has a powerful local ally: local water utilities, which say the revenue generated by selling water to bottlers helps keep costs down for everyone else.
“'Turning away a customer that’s seeking to pay money to the utility because of an alleged problem with extraction would be contrary' to ratepayers’ interests, said Roger Crouse, a board member at the Maine Water Utilities Association. 'If they have a contract that could be expiring in seven years, and the math doesn’t work out, they’re going to have to invest their money somewhere else.'
“Still, hydrologists warn that bottled water should not be discounted as an additional strain on aquifers and watersheds, as well as on residential wells. Last month, the US Geological Survey began its first-ever study of how the activities of the bottled water industry result in changes to groundwater levels, spring flows and water quality. 'Withdrawals, no matter what the use, influence movement of groundwater,' Cheryl Dieter, a hydrologist who is leading the study, said in an interview.
“BlueTriton itself is a creation of Wall Street. It is owned by the private equity funds One Rock Capital Partners and Metropoulos & Co., which paid $4.3 billion in 2021 to buy Nestlé’s North American bottled-water business.
“In Maine, some neighbors of BlueTriton, like Natalie DiPentino, are skeptical of the company for more personal reasons.
“Ms. DiPentino, who lives near Lincoln, can’t prove it but wonders if pumping by Poland Spring contributed to a crisis in her home during a drought in 2017, when her well ran dry along with those of several neighbors. Her family had to haul buckets of river water to flush the toilet, she said. Stores nearby ran out of bottled water.
“After learning about BlueTriton’s proposed 45-year contract at its Lincoln facility, she led calls for a public hearing, arguing that deals were being cut behind closed doors and that Poland Spring would be paying too little, $15,000 a month, for millions of gallons of water. 'You don’t know how badly you need water until you don’t have it in your house,' she said.
“The hearing she sought is now scheduled for next month."
In fact #IDF is literally blowing up every tunnel entry they find on sight...
#Egypt used to pump #Seawater into those tunnels but stopped after protests pointing out this does salten the already overstrained #Aquifers used to pump #freshwater from...
"Engineers designed a solar #desalination system that passively turns seawater into drinking water. It circulates water in swirling eddies which drives water to evaporate and leave salt behind. The resulting water vapor can be condensed and collected while the leftover salt circulates out of the device.
A small suitcase-sized system could produce up to 6 litres of #drinking#water per hour and last several years."
