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
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.
“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.”
“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.”
“There is absolutely no connection,” he said.
“That is an outrageous suggestion”.
And some confirmation from mainstream media. The connections between the Tasmanian floods and cloud-seeding got quite a lot of coverage across Australian media.

Greedy Green Hubris gone wrong? It took months of bad choices to achieve this Gold-Star Moment in Bad Management:
Hydro Tasmania's website is HERE
November 1, 2003
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.
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

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