The Physics of Sandstorms

first_imgMidair collisions of sand particles can double the strength of a sandstorm, according to new computer simulations. The work—among the first analyses to track every sand grain in a virtual storm—could help predict how this destructive weather phenomenon shapes the surrounding landscape.It’s not easy to recreate a sandstorm on a computer. These columns of windswept sand—which can cause roadway pileups, eat away at buildings and machinery, and drive larger processes such as  erosion and dune formation—consisting of many millions of interacting particles propelled by ever-changing winds. Their intricacies overwhelm even the most powerful processors, forcing scientists to simplify their models, says physicist Marcus Vinicius Carneiro of ETH Zürich in Switzerland, lead author on the new research.But as computer speeds have increased, researchers have been able to make their simulations more complex. Recent models reveal a hierarchy within the seemingly chaotic cloud of sand. Just a few centimeters off the ground in a layer called the soft bed, bouncing particles called reptons move in the direction of the wind. A small number of grains called saltons leap high above the bed in a process known as saltation. These grains move much faster and have longer trajectories than reptons, because wind speeds increase with altitude. But physicists have struggled to explain what separates low-bouncing reptons from high-flying saltons, Carneiro says.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)He and his colleagues have been developing a program, first described in a 2011 paper, that follows the trajectory of every grain of sand in a model storm under various wind conditions. They can now simulate the movement of 4000 particles, which, Carneiro points out, is less than a mouthful of sand, but still a leap forward in complexity.In this new research, the team focuses on one feature that previous models have had to ignore: collisions between individual grains in the air. “Mathematical models become simply easier if midair collisions are neglected,” says Eric Parteli, a physicist at the University of Erlangen-Nuremberg in Germany who was not involved in the research. The influence of these interactions on the speed and strength of a sandstorm was initially assumed to be negligible, he says.The team ran simulations to gauge the effect of midair collisions on a storm’s strength, which they measure as flux, the number of particles passing through a given volume of air in a given amount of time. They can switch these collisions on and off in their model to see how flux changes. The team expected that particles bumping into one another would dissipate energy and slow the storm down, Carneiro says, but the results surprised them. Including midair collisions in the model increased the flux, in extreme cases approximately doubling the strength of the storm, they report online this month in Physical Review Letters.“In the beginning, we thought that was a mistake,” Carneiro says. But as the researchers further explored their simulation, they developed an explanation. As a sandstorm gets started, a strong wind lifts some particles off the ground. When they crash back into the soft bed of slow-moving particles, they create a splash, kicking more particles into the air. (This splash effect had been suggested in previous research.) The team dubbed these kicked-up grains leapers. When a grain on its way back down collides with an ascending leaper, the descending grain gets buoyed higher into the air. This is how reptons become high-flying saltons, the team explains. And the splash of descending saltons makes more and more leapers, which buoy more saltons in turn. As sand grains reach altitudes with greater wind speed, the sandstorm escalates.This more detailed and accurate model could help scientists better predict the motion of dunes or manage coastal land threatened by erosion, says physicist Hans Jürgen Herrmann, also of ETH Zürich, who led the research team. He thinks previous models that did not take midair collision into account have been underestimating the strength of sandstorms, making their prediction of a storm’s effects on the landscape inaccurate.This underestimation is most dramatic at higher wind speeds, notes Jasper Kok, an atmospheric physicist at the University of California, Los Angeles, who was not involved in the work. That means models ignoring the collisions would still be largely accurate for all but the most extreme storms. He also notes that numerical models like the team used have their limits. “Even though it’s a really well-done paper and I think the physics all checks out, it needs to be confirmed by experiment.” Such experiments will be a challenge, Kok says, because it’s hard to prevent these midair collisions when recreating a sandstorm in a wind tunnel or when measuring speeds of windblown sand in the field. What’s more, he says, the finding increases the gap between models and real-world studies. “Usually we get higher fluxes than what they measure in the field. And this finding makes it even worse.” If the collisions are as crucial as this research suggests, physicists will have to find some other way to account for the widening gap between the true storms and their digital mimics.last_img read more

Amit Shah chairs 24th meeting of Western Zonal Council in Goa

first_imgUnion Home Minister Amit Shah on Thursday chaired the 24th meeting of Western Zonal Council in Goa. The Western Zonal Council is a forum for the Centre and States to exchange ideas on issues such as health, security and social welfare. Maharashtra Chief Minister Devendra Fadnavis, Gujarat Chief Minister Vijay Rupani, Goa Chief Minister Pramod Sawant, representatives from the Union Territories of Daman and Diu and Dadra and Nagar Haveli attended the meeting. Mr. Sawant is the vice-chairman and host of the meeting. The previous meeting of the Western Zonal Council was chaired by then Home Minister Rajnath Singh at Gandhinagar in Gujarat in April last year. The zonal councils provide a forum where irritants between the Centre and the States, and among the States themselves can be resolved through free and frank discussions and consultations, an official said. The States have been divided into five zones and each zone has its council comprising the Chief Minister, two Ministers and the Chief Secretary of each State. The zonal councils are headed by the Union Home Minister and each zone nominates one Chief Minister as its vice-chairman on rotation basis.last_img read more

Ind vs Eng: Strauss equates India series to Ashes

first_imgEngland Test captain Andrew Strauss considers the upcoming series against India as tough as the historic Ashes but is banking on home advantage to upstage the world’s number one side.”This series against India is certainly up there with the Ashes. I think the one thing we have in our advantage over the Ashes is home advantage,” said Strauss ahead of the series starting July 21 at the Lord’s.”We expect to beat any side at home. And so you should because it is a substantial advantage. But you only have to look at what India have done in the last two years to know they will be incredibly confident,” he added.Tough it might be but Strauss said the prospect of facing the world’s top side is also great motivation to do well.”They have a lot of good players and are heavily motivated to win. We will have to be at our best if we want to compete with them. We’re under no illusions on that, but that excites us.”In international cricket, you always need challenges like this. I think we’re better equipped than in 2007. We’ve had a lot of success recently and we’re a more competent unit.We’ve been progressing every series we’ve played over the last couple of years,” he said.”Over the next four Test matches we’re more than capable of winning. That motivation of playing against the best side in the world is just what we need at the moment,” Strauss added.Strauss takes over from ODI skipper Alastair Cook.advertisementSpeaking about England’s experiment with three captains for all three formats (Stuart Broad being in charge of the Twenty20 side, Strauss said he is still adjusting. “The simple answer is I don’t know how it will be,” he said.”I have seen a few of the lads over the last couple of weeks and it didn’t feel particularly different ? but we never know how things are going to work out. You can’t be sure and it would be arrogant for me to assume that it will be exactly as it was.”But it is not like we are doing radically different things. Alastair, myself and Stuart Broad, we are still operating within a general strategy which we have all had a hand in formulating,” he added.- With inputs from PTIlast_img read more

Just not cricket! Govt and BCCI draw flak for proposing India-Pakistan series in December. Opposition parties, even cricket legends slam the decision

first_imgThe BCCI’s initiative to host the Pakistan cricket team for a series on Indian soil after five years has caused a massive uproar in political circles, divided opinion in the cricket fraternity and pushed the government on the back-foot. Opposition parties, such as the BJP and the Shiv Sena, were quick to slam the decision to resume cricketing ties despite Islamabad’s inaction against the perpetrators of the 26/11 Mumbai terror attacks. Even the Mahrashtra unit of the Congress lashed out at the BCCI for being insensitive towards terror victims. Cricketers too were critical, with legendary batsman Sunil Gavaskar saying: “Being a Mumbaikar I feel what is the urgency when there is no co-operation from the other side.” Faced with severe criticism, the government quickly distanced itself from the BCCI’s announcement. Officials in the Ministry of Home Affairs (MHA) said that the cricket body was “yet to seek permission for the series”. The statement was in contract to senior BCCI functionary Rajiv Shukla’s indication that there was “no problem with the government”. Politicians questioned the need for cricket diplomacy at this juncture, especially since such attempts have failed miserably in the past. In 1987, Pakistani dictator Zia-ul-Haq visited Jaipur to watch a match featuring the two arch-rivals and promote peace between the country. But soon after, in 1989, there was outbreak of Islamabad-sponsored terrorism in the Kashmir valley. In 2005, Pakistan President Pervez Musharraf witnessed the Indo-Pak cricket match at New Delhi’s Ferozshah Kotla stadium. But a series of terror attacks in India again derailed the peace process. More recently, during the 2011 World Cup, Prime Minister Manmohan Singh invited the then Pak premier Yousuf Raza Gilani to watch the semi-final match between the two countries in Mohali. But this peace initiative failed too as Islamabad took no action against 26/11 perpetrators despite it’s promises. The BCCI on Monday announced that it had decided to invite Pakistan to play three one-dayers and two Twenty20 games in December this year.advertisementlast_img read more

Dum Dum Muncipality councillors husband found dead in shop

first_imgKolkata: Mystery shrouds the death of Dum Dum Municipality councillor’s husband. The deceased identified as Nirmal Kundu was the husband of Supriya Kundu, councillor of Dum Dum Municipality. His body was found hanged inside his shop on Monday.According to sources, Supriya and Nirmal used to reside at a flat at Kamalapur in Dum Dum. Supriya was elected as a councillor from ward Number 11 in the last municipality elections. Her husband Nirmal was a popular Trinamool Congress leader. He ran a stationary shop on the ground floor of the building that housed their apartment. Also Read – Centuries-old Durga Pujas continue to be hit among revellersOn Sunday night he went to sleep inside the shop. As he used to sleep there often, Supriya and other family members did not doubt anything suspicious. On Monday morning, their neighbours saw that the lights inside the shop were on. When some of them knocked on the shop’s shutter which was locked from inside, however, no one responded. Immediately they informed Supriya. After a few minutes, she along with other family knocked on the shutter but Nirmal did not respond. They informed Dum Dum police station. The police came and broke the shutter and found Nirmal hanging from ceiling fan with the help of a nylon rope. He was brought down and rushed to Dum Dum Hospital where Nirmal was declared brought dead. Sources claimed that he was going through depression since Trinamool’s result in the Lok Sabha elections in Dum Dum was not up to the mark. Also, he was suffering from various ailments and had almost stopped stepping out of his home. An Unnatural Death (UD) case has been lodged at the Dum Dum police station. No suicide note was found from the incident site.last_img read more

Syrian chocolatier to hire mentor refugees They come here to contribute

first_imgANTIGONISH, N.S. — A one-time Syrian refugee who founded a thriving Nova Scotia chocolate company has announced plans to hire and mentor other refugees.Peace by Chocolate of Antigonish, N.S., has committed to hiring 50 refugees by 2022, and to mentor 10 refugee-run start-ups over the next few years.The now-famous company was founded by the Hadhad family, who fled their home in war-torn Damascus in 2012. They arrived in Nova Scotia with next to nothing in 2016.The company was founded shortly after and quickly found success, bolstered by high-profile shout-outs like one from Prime Minister Justin Trudeau in an address to the United Nations.The family’s remarkable story has been told around the world.Tareq Hadhad, CEO of the company, said Peace by Chocolate aims to give back to the country that welcomed his family when so many nations were closing their borders to the Syrian plight.Now he plans to expand on that vision by giving back to other refugees looking to start new lives — as Canadians did for his family when they needed it most.“They (refugees) come here to contribute, they come here to give back to the community, and as a family that lost everything in the world we know how they feel,” Hadhad said in an interview.“Being a refugee is not a choice, it’s not a decision, it’s not a life goal. These people are fleeing their homes because of war, because of persecution. It is substantial and it’s the responsibility for everyone to do his role in supporting these newcomers to Canada.”Hadhad said the roles on offer will include positions in production, sales, and senior management, nurturing the skills and experience refugees bring with them.Hadhad’s father, Assam, ran a chocolate business in Damascus for decades but it was destroyed in a 2012 bombing.Many of the jobs will be located at new facilities planned for different parts of the country as Peace By Chocolate expands, with locations still being finalized.Hadhad said he hopes other Canadian businesses will follow his lead and support newcomers.The chocolatier added that most Canadians have the generosity of Indigenous people to thank for their successes in Canada.“Everyone when they came here, they received a hand, and now it’s the turn for all these settled Canadians to help,” he said.“We want to support other refugees like our community supported us.”– By Holly McKenzie-Sutter in St. John’s, N.L.The Canadian Presslast_img read more

George Michael died of accidental drugs overdose says his cousin

first_imgGeorge Michael’s cousin has said he suspects the star died of an accidental drugs overdose.Andros Georgiou said the singer had resumed taking “hard drugs” toward the end of his life, but denied his death was suicide.The 53-year-old superstar was found dead at his home in Goring-on-Thames, Oxfordshire, on Christmas Day.Police said a post-mortem had proved “inconclusive” and the results of further tests are yet to be revealed.His death is being treated as “unexplained but non-suspicious”. Speaking to the BBC’s Victoria Derbyshire programme, Mr Georgiou said hard drugs “had been back in [Michael’s] life” and crack cocaine was a “favourite”, but he denied the singer used heroin.”I just think he took too much of something, mixed with antidepressants and other drugs he was on – with alcohol,” he said.”I think his heart just stopped beating.” The former record producer rejected speculation that Michael had taken his own life after suffering from depression.He said: “I believe he had suicidal thoughts, because his mental health was all over the place. But I don’t believe this was suicide.”Mr Georgiou worked with Michael at the height of his fame, although the pair became estranged in 1998.He paid tribute to the “incredibly generous” star who was “one of the nicest people you could ever meet”.

Albion cane harvester conned by bandits

A cane harvester attached to the Albion Estate, Berbice is now left counting his losses after bandits on Monday conned him of his gold jewellery.According to information received, the man was at home when he received a call where the caller purported to be a representative of the GTT in New Amsterdam.He was instructed to report to the GTT office there in relation to his phone line, which the caller told him he would lose if he failed to go to the office.This publication understands that the man left his home to go to the utility company.While on his way to the company, a call was then made reportedly by the same perpetrator to the 12-year-old son of the cane harvester.He was instructed to collect all of the gold jewellery in the house and take it to the New Amsterdam Hospital.Sources close to the Police confirmed that the boy gathered the jewellery belonging to his mother and sister totalling in excess of $200,000 and took it to the hospital.When he arrived at the hospital, he was sent to the back where he was instructed to leave the jewellery on a table.Moments later, he was told to go back for the jewellery, but when he did it was not there.Information surrounding the entire incident is sketchy; however, the Police have launched an investigation.

Kickstarter Launched to Wipe the Rat From the End of The Departed

first_imgStay on target Kickstarter is a truly amazing thing. We’ve seen some extremely innovative products and wonderful creative projects launched there. There are also plenty of Kickstarters that are awesome because of their absurdity.There was that whole potato salad thing, which raised more than $55,000 and got more looks than the original Oculus Rift and Reading Rainbow Kickstarters.Now there’s a guy who wants $4,000 to digitally erase the painfully obvious symbolic rat from the end of Martin Scorsese’s The Departed.The Departed was a good movie with a very bad ending. Here’s my explanation of the problem. pic.twitter.com/loXLMbqLDj— Erase the rat in The Departed (@RatErase) February 19, 2019The project is clearly not something that creator Adam Sacks just hastily threw together. He’s carefully laid out the entire process and crunched the numbers to arrive at his funding goal.Sacks will start by buying a copy of The Departed on Blu-Ray, as well as a Blu-Ray player to play it on. He’ll also need to purchase Blu-Ray ripping software.Once he’s got a digital file that can be worked with, Sacks will hand it off to visual effects artist Ed Mundy for the actual editing. He plans to pay Mundy $599 for his assistance, because $600 is the point at which you have to file tax forms with the IRS and he doesn’t need that hassle.Once Mundy has done his thing, Sacks will pay to have a film print made — just like Scorsese’s original. Then it’ll be converted back to digital. $57.69 for a month of Adobe CC access will let Sacks splice in the rat-free closing scene.Erasing the rat from the end of The Departed is a simple 9 step process. pic.twitter.com/hN0aCjxtSO— Erase the rat in The Departed (@RatErase) February 19, 2019Another $38.31 will go toward blank Blu-Ray discs that will be used to burn the finished product. $2.71 will cover a black Sharpie to “properly label” the discs (what’s more proper on a burned disc than Sharpie?).A pledge of $70 will get you The Departed minus rat. Well, technically it gets you a sealed copy of the Blu-Ray which Sacks will helpfully throw away for you and replace with the expurgated version.Assuming Sacks gets the $4,000 he’s after and the studio’s legal team doesn’t fire off a c & d, this is definitely a thing that could happen.More on Geek.com:10 Reasons ‘Into the Spider-Verse’ Is the Best Spider-Man Movie EverJason Momoa Joins Cast of ‘Dune’ RebootThe ‘Captain Marvel’ Website Is a Throwback to ’90s Design Keto Turns Your Smartphone Into Your Car KeysCovert Dock for Nintendo Switch Fits in Your Pocket last_img read more

Morata blames Contes playing style for Chelsea struggles

first_imgChelsea striker Alvaro Morata believes that Antonio Conte’s direct style was the cause for his underwhelming first seasonThe Spanish forward failed to live up to his £60m price tag in last summer’s move from Real Madrid after scoring just three times in his final 23 appearances.Morata had been heavily linked with a move away from Chelsea this summer, but he is determined to prove his worth.“For me, it’s easy. I could have gone back to Spain or Italy, all the people believe in me there, but I want to change things here. I want to, not for all the haters, but for me and for Chelsea.“Chelsea gave me everything that I needed and now I have time to give back all that Chelsea gave me,” said Morata, according to Sky Sports.The 25-year-old is confident that he will flourish under new manager Maurizio Sarri’s footballing philosophy.Tammy Abraham, ChelseaChelsea hat-trick hero Tammy Abraham hopes for more Andrew Smyth – September 14, 2019 Tammy Abraham hopes this season will be his big breakthrough at Chelsea after firing his first hat-trick for the club in Saturday’s 5-2 win at Wolves.“The most important thing is the way we play,” he said.“Last season it was direct balls and for me to protect the ball in the air is not my best quality“Now I can attack the space, I can play one touch and go in the area for the crosses. It’s better for me.“Sarri works with the ball always and when you always have the ball the strikers have more chances. I want to score more than 30 goals, but I would prefer to score 15 or 20 and get the Premier League or one big trophy.”Morata opened his scoring account for the 2018/19 campaign for Chelsea in their 3-2 victory over Arsenal in Saturday’s London derby at Stamford Bridge.last_img read more

Portland police investigating fatal collision

first_imgEarly this morning, Tuesday November 16, 2010 at approximately 1:31 a.m., Portland Police officers responded to the report of a motor Portland Police Traffic Investigators have identified the drivers of last nights fatal crash. The driver of the 2000 International Tanker Truck that was rear-ended has been identified as 53-year-old Gregory Rupert of Seattle.

Herrera Beutler joins Obama salute of Seattle Seahawks

first_imgWASHINGTON — President Barack Obama can appreciate a team overcoming long odds.Welcoming the Super Bowl champion Seattle Seahawks to the White House on Wednesday, Obama took note that some football analysts hadn’t seen Seattle as a top-tier team. A die-hard fan of his hometown Chicago Bears, Obama nevertheless said he felt a certain kinship with the overachieving Seahawks.“As a guy who was elected president named Barack Obama, I root for the underdog,” the president joked.Joining in the festivities was U.S. Rep. Jaime Herrera Beutler, R-Camas, who chatted with the president after the ceremony.The Seahawks clinched their first Super Bowl victory in the history of the franchise in February by beating the Denver Broncos 43-8.The distinction for the team and by extension for the NFL came a day after a group of retired players accused the league in a lawsuit of turning a blind eye to the use of painkillers by teams that later led to serious complications.Obama has expressed misgivings about the violence of the sport, saying in an interview with the New Yorker published early this year that if he had a son he would not let him play pro football. Next week, Obama will hold a White House meeting on concussions and sports safety at the White House that will include young athletes, professional athletes, parents, coaches and health experts.In a nod to that controversy, Obama took note of Seahawks owner Paul Allen’s charitable foundation that has donated millions of dollars to research traumatic brain injuries. “Obviously this is a concern of the NFL, but is also a concern of our troops,” Obama said.Obama singled out the team’s outspoken cornerback, Richard Sherman, for being a role model to young people. Sherman was born in Compton, California, once a center of gang activity and a city that suffered from severely underperforming schools. Sherman however was a standout student who attended Stanford University on a scholarship.last_img read more

Senate Passes State Spending Limit

first_img“Alaska must control its spending in order to refill our savings accounts and sustain constitutionally required programs Alaskans rely on in their everyday lives,” said Senate Majority Leader Peter Micciche (R-Soldotna). “Senate Bill 196 will help constrain the growth of government, so in the future we don’t find ourselves in the same difficult fiscal situation we face today.” “Had we had an effective spending cap in place during the fiscal years of 2006 through 2014, we would have about $15 billion in our Constitutional Budget Reserve right now,” said Sen. Natasha von Imhof (R-Anchorage). “A spending cap could give the Legislature the discipline it needs to keep state spending at a reasonable level from one year to the next.” Facebook0TwitterEmailPrintFriendly分享The Alaska Senate today passed a bill to limit the growth of state spending. The limit does not apply to appropriations to the Alaska Permanent Fund, payments for Permanent Fund dividends, required spending for state debt obligations, capital projects, or to meet a state of disaster declared by the governor as prescribed by law. The bill also has a three year “look back” provision to evaluate how the limit is working. “SB 196 plants a seed for a future tree of fiscal sustainability for Alaskans,” said Sen. Micciche. “Had the Legislature passed this bill 15 years ago, we would have billions more in savings, new taxes would not be a primary objective for the current House Majority, and it’s unlikely the governor would have cut Permanent Fund dividends.” To promote transparency with the public, the bill requires the governor to submit a report, along with the budget, comparing the governor’s spending proposal with the spending limit. In addition, the spending limit adjusts over time to reflect changes in inflation. The spending limit is a key priority for the Senate Majority. The Senate passed a spending limit in 2017 paired with a bill that placed guard rails around draws from the Permanent Fund earnings reserve, but the spending limit provision was rejected by the House Majority. This year, the Senate passed the spending limit as a standalone bill to simplify negotiations with the House on a solution to the state’s budget deficit. SB 196, sponsored by the Senate Finance Committee, caps unrestricted general fund (UGF) spending at $4.1 billion. SB 196 passed the Senate by a vote of 13 to zero after Senate Democrats opposed the bill during the floor debate and chose to not participate in the vote. The bill is now on its way to the Alaska House of Representatives for consideration.last_img read more
