Revealed: The Australian companies manipulating our weather


Yesterday I covered Dr. Naomi Wolf’s reporting on cloud seeding and geoengineering. She made reference to Australia as one of the countries that has been cloudseeding.

It seems that, in Tasmania at least the Tasmania Hydro’s program has been suspended after it was demonstrated that major floods were preceded by several days of cloud seeding.




Here is some background.

But first there is this. The poisoning of the atmosphere is turned into a cute human interest story

The technology, which was used by the Chinese government to prevent a downpour during the 2008 Beijing Olympics, is becoming more mainstream.”
Company guarantees a rain-free wedding day with cloud-seeding service
TIE THE KNOT WITH HI-TECH: Could "rain on your wedding day" be a thing of the past?

10 March, 2015

Mid-1990s songstress Alanis Morissette sang that rain on your wedding day was Ironic.

While "ironic" might not have been the word Morissette was after, rain on a couple's big day is certainly annoying, particularly if an outdoor ceremony is involved.

But, for just £150,000 ($NZ308,000), one company is willing to guarantee blue skies while you tie the knot.

London-based Oliver's Travels, a luxury travel company that specialises in destination weddings, is now offering a cloud-bursting service for its clients.

"Here at Oliver's Travels, we've helped countless happy couples arrange the destination wedding of their dreams by pairing them with a perfect venue and making sure the food, drinks and entertainment are exactly what they've always wanted," the company says on its website.

"But one thing always bugged us – we can help plan everything down to the last detail, but there was one thing we could never really change: the weather. So we decided to do something about that."

The service uses silver iodide particles to essentially "pop" the clouds before they are due to produce rain.

The company employs a meteorologist, who studies the wedding venue's weather patterns for a week before the big day.

The day before the event, a pilot flies over the site of any identified rainclouds, spraying silver iodide into the air, which attracts moisture in the cloud, turning the cloud's condensation into ice crystals, delaying the rain.

Natasja Rasmussen, head of customer experience at Oliver's Travels, told Discover that the technology, which was used by the Chinese government to prevent a downpour during the 2008 Beijing Olympics, is becoming more mainstream.

"Cloud seeding is now considered a mainstream tool," she said. "New technology provides much more reliable results, meaning we can guarantee the perfect day."

Despite this, Oliver's Travels are yet to sign up a client since debuting the service earlier this year.

And here is some background written on the topic.

Revealed: The Australian companies manipulating our weather


25 June, 2018

Cloud seeding is a method of artificially generating additional rainfall from clouds through technology. It may involve attempting to produce rain when none would normally fall or it may be working to increase precipitation over a particular area.
For over five decades in Australia, the study of clouds, rain and the atmosphere has been largely hidden from the public, as a secretive network of private business interests and faceless corporate entities continue to manipulate the weather around us to their benefit.

CSIRO & CLOUD SEEDING:

Experiments of the cloud seeding theory began in Australia shortly following the world’s first laboratory trials, after new research papers published by USA researchers I Langmuir and V Schaefer stated that rain could be induced by seeding clouds with dry ice.

After a series of experiments in New York, the two researchers managed to make it rain using silver iodide bullets. They got a patent for their technique, referred to as cloud-seeding, soon after.

As a result of the international study, cloud seeding was first trialed in Australia in 1947 when the CSIRO used Royal Australian Air Force aircrafts to drop dry ice into the tops of cumulus clouds.

According to CSIRO history, the method worked reliably with clouds that were very cold, producing rain that would not have otherwise fallen, leading to more subsequent trials.

The first documented date of this success was in 1947. Described by CSIRO:
This is believed to be the first documented case anywhere in the world of an appreciable man-made rainfall reaching the ground and the first time that dynamic cloud growth had followed seeding.”

Following the success of initial trials, CSIRO scientists would continue this work until 1952, soon expanding to include theoretical, laboratory and airborne investigations of cloud structure and reaction.

CSIRO carried out similar trials from 1953 to 1956 in South Australia, Queensland and other states, however this time covering a large area instead of singular clouds as before.

Experiments used both ground-based and airborne silver iodide generators to gain results. Each experiment covered a target area of 2,000 to 8,000 square kilometres and a neighbouring control area of the same size which was not seeded.

During the late 1950s and early 1960s, CSIRO performed cloud seeding in the Snowy Mountains, on the York Peninsular in South Australia, in the New England district of New South Wales, and in the Warragamba catchment area west of Sydney.

CSIRO’s activities in Tasmania in the 1960s were also successful, with seeding over the Hydro Electricity Commission catchment area on the Central Plateau achieved documented rainfall increases as high as 30% in autumn.

The Tasmanian experiments were so successful that the Commission has regularly undertaken seeding ever since in mountainous parts of the state.
Furthermore, striking results documented across Australia held such promise at the time that new systematic programs of cloud seeding were set up as a result for the next fifty-years.

This work is done today by the CSIRO Division of Cloud Physics under the ‘Marine and Atmospheric Research’ division.

THE PLAYERS:

Cloud seeding continues across Australia in 2018 – and is more advanced than ever.

Today, while some government-run projects exist, the most popular type of project involves coordination between the government and a private company.
A key example of a modern operation currently bringing these experiments to the modern era – one of two of the largest in Australia – is weather and water experimental company, Snowy Hydro, based out of the Snowy Mountains in NSW.

Following initial trials in 2004 in the region, Snowy found that the “exceptional scientific merit of the trial”“positive results of the evaluation”, and “absence of adverse environmental impacts” were sufficiently ‘compelling’ for the government to pass legislation for an ongoing, operational cloud seeding program.

James Pirozzi, manager at Snowy Hydro, explained how their technology works and has developed in the 21stcentury:
We’ve got a series of ground-based generators on the western side of the Great Dividing Range in the Kosciusko National Park, and we use the natural terrain features in the wind to give us uplift to get that material from the ground up into the clouds,” Mr Pirozzi said.
Those generators, the burners themselves [are] essentially a big propane flame.”

The cloud seeding activities undertaken by Snowy Hydro are authorised by the Snowy Mountains Cloud Seeding Act 2004 (Act), which prescribes a number of mandatory requirements for cloud seeding programs in NSW.

2009 paper looking into cloud seeding found “overall rainfall over targets was somewhere between 5 per cent and 13 per cent greater than over a nearby control region”.

Another recent peer reviewed paper suggested an average 14 per cent increase in rainfall due to recent Snowy Mountain cloud seeding trials.

A company by the name of Hydro Tasmania conducted were also recently under fire for cloud seeding in the lead-up to deadly flooding in north-western Tasmania that resulted in a coronial inquest.

It was later found in a DPAC review that the seeding from Hydro “had no measurable impact on precipitation” — despite the flight lasting for an hour and 34 minutes over the Upper Derwent catchment, targeting Lake Echo.

The review found the cloud seeding flight did not contribute to subsequent flooding of 2016.

Hydro Tasmania’s cloud seeding operation has been on hold since the incident.
Weather Modification, Inc. also supported the Queensland Environmental Protection Agency during their 2008 ‘Feasibility Study for the Augmentation of Rain & Air Chemistry Monitoring’ – providing an instrumented aircraft and crew for cloud seeding.

In December 2006, the Queensland government announced $7.6 million in funding for “warm cloud” seeding research to be conducted jointly by the Australian Bureau of Meteorology and the United States National Center for Atmospheric Research.

These are only a few examples!


THE MURDOCH CONNECTION:

Current Prime Minister Malcolm Turnbull announced in 2007 that $10 million from the Australian Government Water Fund will be given to the investigation of an ‘untried technology’ that aims to trigger rainfall from the atmosphere, even when there are no clouds.

The money bankrolls research into mysterious ionisation technology promoted by the secretive Australian Rain Corporation (now Australian Rain Technologies), in hopes of using forthcoming trials to show the technology can bring increased rain.
In a sense, the company will be taking methods previously discussed above, and adding electrification of the ionosphere to create clouds out of thin air, even when there is no rain.

Mr. Turnbull’s office says there was no breach of caretaker protocol because the project was actually approved before the election was announced.

Malcolm Turnbull’s fundraising group, the Wentworth Forum, includes a long list of generous donors responsible for this move, including Frank Lowy, Ros Packer, John Simons, and Matt Handbury – chairman and part-owner of the Australian Rain Corporation!

It has been revealed that Mr. Handbury is the wealthy nephew of Rupert Murdoch and chairman and proprietor of Murdoch Books, which is the headquarters for Australian Rain Corporation!

All starting to make sense now?

Malcolm Turnbull was asked the following question in relation to the connection by the ABC in  2007: Has Matt Handbury’s contribution to your fundraising Wentworth Forum helped in securing funding for the Australian Rain Corporation?
There is absolutely no connection,” he said.
That is an outrageous suggestion”.

Requests for interviews with Mr. Turnbull, the head of the Australian Rain Corporation, the head of the center contracted to test the device were declined.

Climate control gone wrong: Tasmanian Hydro seeded clouds before disastrous floods



11 June, 2016

Greedy Green Hubris gone wrong? It took months of bad choices to achieve this Gold-Star Moment in Bad Management:

Tasmania’s state-owned Hydro-electric power generator could face legal action for damages after admitting it cloud-seeded in or near water catchments the day ­before disastrous flooding, although heavy rain was forecast.

Tasmania  shut their only fossil fuel power plant in August last year, and relied on renewable energy and one sole Basslink electricity cable to mainland Australia. The cable was supposed to be a back up supply but was bringing in 40% of Tasmania’s electricity, and it broke in December. But a green and greedy approach in Tasmania meant that the state had already run its dams down to 26% levels by selling too much electricity to the mainland at high “renewable” subsidized prices. That was a low level at the start of summer, normally a drier season in Tasmania. After the Basslink cable broke, the dam levels fell to a precipitous 13%, so fast that the green state had to bring in diesel generators just to keep the lights on. They also switched back on the Tamar Gas plant in late January. So much for being the “100% renewable” state.

When rain was forecast in June the hydro managers must have been delighted, but even faced with the forecasts  they seeded clouds on June 5th as well. (Rivers were rising on June 4 and flood warnings were valid for many areas of Tasmania.) This was the same storm system that hit Sydney on its way to Tasmania, causing deaths and threatened houses. Flood damage and losses from that same system in Tasmania now amount to around $100 million. One man is still missing, feared drowned....

In August 1952, the RAF in Britain conducted Operation Cumulus, which involved gliders spraying clouds with dry ice, salt or silver iodide. Within days North Devon received 250 times its normal August rainfall. The town of Lynmouth was virtually washed away and 35 people were killed.

The link between the experiments and the flood has not been proved and cloud seeding over mainland Australia has also been inconclusive, according to the CSIRO.

But artificial rainmaking has its supporters, and a House of Representatives inquiry into water supplies has reignited their dispute with the CSIRO.

Only Tasmania conducts cloud seeding, although in August, Snowy Hydro announced it would undertake a six-year $5 million trial in the Snowy Mountains, spraying clouds with silver iodide from generators on the ground.

Snowy Hydro predicts that snowfall could increase by 10 per cent and could deliver improved environmental flows to the Murray River.

The federal member for Mallee, the National Party's John Forrest, is Canberra's main advocate of cloud seeding.

A Melbourne weather research company, Australian Management Consolidated - which advocates the research of Israeli meteorologist Danny Rosenfeld - has also given evidence to the inquiry, which expects to finish its report early next year. AMC and Professor Rosenfeld say pollution from the Latrobe Valley and Melbourne has caused drought in Gippsland and the Alps by hindering the way clouds release rain. Cloud seeding would rectify the problem, they say.

The head of cloud seeding at Hydro Tasmania from 1990 to 2002, Ian Searle, said the process boosted rainfall in Tasmania's catchment areas by about 87 millimetres a year.

"In my view, the current CSIRO view is based on some rather unhappy experience they had and I think it's flawed," Mr Searle told The Age.

Monthly rainfall varies greatly from year to year. Trying to prove rain was caused by cloud seeding would require a long, expensive experiment. The CSIRO says the trials it conducted in Victoria in the 1970s and 1990s were unable to prove that cloud seeding worked.

Mr Searle disagrees. He said a trial in Tamworth in 1994 was inconclusive, but farmers found it useful. "In my view . . . it was an outstanding success," he said. "People would call up and say they got so much rain. They were very happy."

John Forrest - who says 40 countries, including South Africa, the United States and China practise weather modification - visited Texas last year, where cloud seeding is practised over a third of the state. Like AMC, he says pollution is hampering rainfall, but cloud seeding with salt will fix it.

"The (clouds) are full of aerosols and dust and industrial pollutants which impairs the rain-producing capabilities of the cloud . . . $5 million would give us a good (cloud seeding) program over six or seven years," he said.

The CSIRO says the money could be better spent elsewhere.

"Over Victoria, there is absolutely no reason at all, no evidence, that pollution has an effect on rainfall," the CSIRO's climate modelling team leader, Brian Ryan said, before adding that the climate "is so complex we can't rule anything out".

Dr Ryan said the decline in the state's rainfall was more likely the result of natural variability and the greenhouse effect.

While he agreed that the Snowy Hydro trial would be a good test of cloud-seeding technology, he said the US National Academy of Sciences this month found there was no evidence that cloud seeding worked.


Tasmania's government-owned energy company has been asked to explain why it conducted cloud seeding over the Derwent River catchment the day before flooding began this week.

In the state's north, one person was killed and another remains missing.



For centuries mankind has dreamed of changing the weather at will, to reverse drought, stave off destructive storms or to water crops.

Climate change aside, most of those attempts have been little more than wishful thinking. But when the snow begins to fall in Kosciuszko National Park in a few short months time, it will be getting a helping hand – from a utilities company.

Officials with electricity generator Snowy Hydro are installing a series of burners along the western edge of Kosciusko national park. Those burners are part of a large network of equipment and expertise the company plans to use to increase the amount of snow falling in the NSW alps this winter.

With more than 10 years of scientific trials complete, the company has been given the green light by the NSW Government to conduct regular cloud seeding operations, a move that has some environmentalists worried, despite the strict operating restrictions placed on the program


Hydro Tasmania to conduct a review of its cloud seeding operation



August 1, 2016


THE future of cloud seeding in Tasmania is unclear, as Hydro Tasmania embarks on a review of the controversial practice.

Hydro released a report on Friday on a cloud seeding flight over the Upper Derwent catchment on June 5, the day before deadly floods hit the region. The report said the cloud seeding did not have a measurable impact on the floods.
But cloud seeding in general will now be subject to a review – and there is no word on when it may resume.

Tasmanian waters are waring more quickly than the rest of the world

Waters off Maria Island warming more quickly than the rest of the world
WATERS off Maria Island on Tasmania’s East Coast will be as warm as those at Batemans Bay in New South Wales as early as 2060, according to a new Senate Inquiry report.


7 December, 2017



The report into the impacts of climate change on marine fisheries and biodiversity was tabled in Federal Parliament yesterday, with Tasmania a key focus.

IMAS scientist Professor Stewart Frusher told the inquiry that waters off Maria Island were already as warm as waters off Eden in southern New South Wales were in the 1940s.

His colleague Dr Neville Barrett said the waters near Maria Island would warm to the same temperatures as those off Batemans Bay by “at best case, 2100 and, at worst case, 2060.”

The warming is related to the increased strength of the East Australian Current.

The CSIRO submitted that “for the Tasmanian coast, it is expected the water will continue to warm faster than the rest of the world as more warm East Australian water moves southward ...”

Tasmanian Greens Senator Peter Whish-Wilson instigated the inquiry after a marine heatwave hit Tasmania’s East Coast in 2015-16, with temperatures 2.9C above average for 250 days.
The report noted temperature increases had caused issues in growth rates of salmon, abalone and rock lobster.
The report addressed the impacts of Pacific oyster mortality syndrome and kelp forest deaths due to urchin barrens — impacting on habitats and biomass of abalone and rock lobster.
The report made 15 recommendations to the Federal Government including:
A REVIEW into funding provided for research into the effects of and adapting to climate change on the marine environment.
BUILDING relationships between the fishing and aquaculture industry and research organisations to help industry understand and adjust to the effects of climate change.
Senator Whish-Wilson said Tasmanian scientists and aquatic industries needed to discuss climate change together for both the environment and industry.
Tasmania is a global hotspot for warming oceans and is showing signs of rapid, frightening change, quite unlike other parts of the world,” Senator Whish-Wilson said.
We need to employ a co-ordinated approach across science and industry to work out what this change means for our state and put in place plans that build resilience for industry and the environment to better deal with it.”

Extreme weather in Tasmania

BREAKING NEWS!! 165KM/H WIND GUST ON TOP OF MT WELLINGTON, TASMANIA 1130AM

This is the equivalent of category 3 cyclone!

ROARING DAMAGING WINDS CONTINUE TO BATTER TASMANIA!! Please stay safe and secure all loose objects!!

Winds will moderate a touch tomorrow.

Tasmania weather: Wind gusts of 150kph batter Hobart, 3,000 without power
  • Mount Wellington recorded strongest gusts of 165kph
  • SES warns people to not undertake any unnecessary travel
  • TasNetworks flooded with calls as thousands of homes blacked out

ABC,
14 July, 2016

Damaging winds with gusts of up to 150 kilometres per hour are continuing to batter Tasmania as crews work to restore power to 3,000 homes and businesses.

The State Emergency Service (SES) is dealing with dozens of call-outs and some residents around Hobart have been without power since Tuesday.

Houses have lost roofs and buildings in Hobart's CBD have been damaged, including the Vodafone building in Bathurst street, which had a 10th floor window frame blown in.

A statement from Vodafone said a large window frame containing six windows blew inwards.

Hobart's Mount Wellington recorded one of the strongest wind gusts, clocking 165kph about 11:30am.

SES regional manager Mark Nelson warned people to avoid unnecessary travel.

"There is a lot of potential for damaged trees, powerlines down, power outages," he said.

"Be aware of dangerous road conditions as well, there's going to be a lot of debris on the roads.

"If you can, just avoid walking and driving out and about because there's just a lot flying around."

The SES repeated warnings to secure outdoor furniture and equipment, after a trampoline landed on a neighbour's roof.

TasNetworks spokeswoman Jacquie Collis did not say when power would be fully restored adding the company had been overwhelmed with calls for help.


"[We were] responding to 1,000 calls an hour yesterday, and we've tripled our staff levels," she said.

Fifty crews were out prioritising larger areas such as Glenorchy and South Hobart, but there was no estimate of when the Tasman Peninsula would be back on line.

Police closed Strickland Avenue in South Hobart between the Cascade Brewery and Huon Road, where a tree was down and winds were damaging homes.

Tasman Mayor Roseanne Heyward said residents and businesses on the Tasman Peninsular were struggling to cope with ongoing power outages.

"The main complaints that I get are the fact that they can't connect, there's no internet, there's no phone," she said.

"Places like the medical centre or the historical site, businesses that rely on power, the cafes of course and restaurants can't open so they lose money. It's a big problem."




Trimming trees could have prevented blackout, resident says

Claire, a resident of Summerleas, located south of Hobart, told 936 ABC Hobart she had been without power overnight.

"We've been out of power since ten o'clock Tuesday night," he said.

"We have tank water and that, which means we've got no water, no power, no internet, no nothing.

Joe from South Hobart said he had been without power for the best part of two days but pre-emptive action could have prevented the blackout.

"You can bet every time there's a weather event we're the first to lose power," he said.

"The reason, there are trees within metres of the lines which fall across the lines and road.

"The fix is simple. Cut or trim the trees. It's called preventative maintenance.

"It'd surely be less expensive than emergency call-outs and the back-pay cheques that we receive

"Would it take a life to be lost before action is taken."

The weather bureau has also issued a flood watch for the south.

Forecaster Alex Melitsis said between 30 and 80 millimetres was expected in the west, with the rainfall flowing into southern river basins.

"With this very strong westerly airstream, we're just seeing moisture being pumped into the west and very heavy shower activity into the west," he said.

Strong winds yesterday caused about $1 million damage at Hobart's showgrounds and a man was trapped after part of a building collapsed in central Hobart.

Meanwhile , in New Zealand









Truck drivers have been warned not to use the Auckland Harbour Bridge as strong winds hit.

Wild winds have ripped through the centre of the country, crushing fences, felling trees and cutting power to hundreds.

A thunderstorm which tore through Paraparaumu, north of Wellington, on Thursday morning left fences crushed under fallen trees from a possible tornado.

MetService meteorologist Emma Blades said the "band of thunderstorms" that crossed the area about 2am were extremely strong.

"It could have been a tornado or it may have just been a line. There was rain off and on all night and seems to have peaked [about 5am]."

By midday Auckland Transport was warning of speed limits and strong gusts - up to 90kmh - on the Harbour Bridge.

The New Zealand Transport Agency said at 1.30pm on Thursday that gusts of up to 90km/h were recorded and were expected to continue for the next few hours.


This damage was reportedly left by a tornado in Paraparaumu which happened overnight on July 13, 2016.

"High-sided vehicles and motorcyclists should consider using State Highway 16 and 18 as an alternative route," said agency spokeswoman Sarah Azam.

"Road users should take extra care and increase their following distance."

MetService meteorologist Lisa Murray said the mean wind speed around the bridge was 48km/h, gusting up to a gale-force 83km/h.

"With gusts of that strength, you need to be concerned, high rise vehicles or light vehicles can be pushed around.

Meanwhile, storms across the Nelson region left hundreds without power. Network Tasman chief executive Wayne Mackey said crews worked in hazardous conditions to try to restore electricity to customers.

Further south, ski fields are in for a welcome dump of snow as winter closes in.

More rain, strong winds and snow to low levels are all on the cards for many parts, particularly the South Island, throughout Thursday and into Friday.

Snow is set to dump between 10cm and 15cm at Coronet Peak, the Remarkables, Cardrona and Ohau ski fields.

State Highway 94 remains closed between Te Anau and Milford.

Severe thunderstorms, possibly with small coastal tornadoes, could hit Westland and Buller north of Harihari from 6am to midday Friday, and south of Harihari in Westland and Fiordland between midnight and 7am.

Damaging wind gusts up to 110kmh could accompany the thunderstorms. "Wind gusts of this strength can cause damage to trees, power lines and unsecured structures and may make driving hazardous. If any tornadoes occur, they will only affect very localised areas," MetService said.

MetService meteorologist Erick Brenstrum​ said the worst of the overnight system had passed and heavy rain was starting to ease for most parts. The heavy rain band was moving east over the Bay of Plenty, he said.

Overnight, 300mm of rain fell west of the divide in Westland and spilled over the Southern Alps to bring snow and rain to central and eastern parts of the South Island.

"This has been one of the events where the rain has not been confined to the Southern Alps. It's also done this thing called spillover. Rain has been sweeping across the North Island but the front has not been as active.

"The front that caused the rain in the west is now over the Bay of Plenty and should be east of the North Island by midday. With the front having moved east of much of the country the winds have dropped.

"This air coming in on Thursday is colder. That's causing snow.

"It's snowing at the Milford tunnel. It's likely snow's down to low levels."

OUTLOOK FOR FRIDAY...LESS DRAMA

Brenstrum said an approaching front overnight to Friday was forecast to bring another band of heavy rain and possibly severe gales.

"Then we go into a southwest flow where it continues with showers in western areas. For most parts of the country it's less drama.

"The second front's west of Fiordland about midnight [Thursday]. That should have cleared the whole of New Zealand by Friday night. By far and away the biggest weather producer is over the Bay of Plenty [on Thursday]. The front coming tonight is significant and I think we'll be putting warnings on it.".

Severe northwest gales between 130kmh and 140kmh hit Wellington, Marlborough, the Wairarapa, Taranaki, Wanganui and Taihape on Thursday morning.

Road snowfall warnings are in effect, with snow expected to low levels in Otago, Southland and Canterbury. Snow showers on Thursday are forecast to dump 6cm of snow on the Lewis Pass, up to 8cm on Arthur's Pass, 2cm on Porters Pass and 7cm on the Lindis Pass in Central Otago.

Up to 30cm of snow was forecast to fall around Milford and State Highway 94 between Te Anau and Milford remains closed.

Auckland can expect rain and 16C, Napier gets morning rain then clear conditions and 17C while Wellington is forecast to get rain, thunder and gale force gusts.

In the South Island, Nelson can expect showers, strong westerlies and 15C, but Christchurch has a better day ahead than most with some cloud, wind and 14C.

For Greymouth, it's heavy rain, strong westerlies and thunderstorms with a maximum 12C.

Morning showers are forecast for Dunedin with some cloud and 11C.
