Victoria is driving down Blackout Drive. They have reports from South Australia up ahead, they know where the road goes, but the state is paying for the first class ticket on a trip to RiskyGrid.
Victoria has 5.7 million people, over three times bigger than South Australia. Right now SA relies on the Victorian grid stability to keep running, and gets up to 800MW of reliable electrons from the state-next-door. But Victoria wants to add more wind power — theoretically the equivalent of a big coal fired plant (like Hazelwood).
Tom Quirk and Paul Miskelly looked closely at the numbers and patterns and see the writing on the wall. To help expensive, unreliable, intermittent green energy survive the government subsidizes it by around 9c per KWhr (bear in mind the wholesale rate for coal fired power is 3 – 4c per kWhr.) The government also demands retailers have a 12.5% mix of renewables, and that they accept most electrons from wind power whenever and wherever it is available. This strange anti-free market rule is called “nondispatchable” power, meaning the system can’t just throw it away if there is any demand at all. Whereas coal [...]

Climate change and the Victorian bushfires: this is not a coincidence
Klose tells us climate change is too complicated for stupid people:
“The issue of bushfires can’t be divorced from climate change. For too many people climate change remains an esoteric concept – something that may happen to someone else in the hazy, far-off future.”
Luckily gifted people, like Cambell Klose (political adviser) can “feel” the causes of climate change.
“Clearly this isn’t the case. The effects of climate change are being felt right now and it is having real impacts on Australians and people all across the world.”
Who needs computer models? (Or for that matter, thermometers?)
What not to do when faced with infernos:
“Yackandandah is trying to do something about this. The community has committed to powering themselves entirely by renewable energy by 2022.”
Some people reduce fuel-loads, others fight off the flames with a solar panel.
Wind farms may reduce bush fires if we have to chop down large tracts of forest to install them. Otherwise they make expensive fire-breaks.
More errors in ACORN – The Bureau of Met wonder-database corrects for mysterious “statisticals” but not for 15 story buildings built next to the thermometers. They correct a step change that doesn’t occur in minima, but don’t correct for one that does in maxima. Big site changes are marked in some datasets but not in others. And where is the correction for obvious urban heat island effects? Bear in mind, the size of the artificial steps and corrections is on a par with the warming supposedly due to carbon dioxide. Hmmm.
The BoM database needs to be independently and publicly replicated, all the way from their raw data to the final output down to several decimal places. Then we will all know what is going on. Let’s shine a light in. If it ain’t replicated, it ain’t science.
Melbourne has one of the longest temperature records in the Southern Hemisphere. Looking at the original records it appears Melbourne maximums have not changed much from 1855 – 1995. Then they suddenly jumped or stepped up.
Tom Quirk did some sleuthing, and figured out why that happened. But what he can’t figure out is why the Bureau missed this adjustment, yet makes [...]
Rutherglen is one of the seemingly best stations in Australia, apart from a break from 1955-1965. Bill Johnston looks closely at the raw data, finding that there is probably no trend — flat temperatures — rather than either cooling or warming. And that it’s difficult to fill in data from surrounding stations. He speculates that something fishy goes on in 1924. He also finds that rainfall probably drives a fifth of the temperature swings. He discusses his disappointment at the intellectual level of debate on The Conversation.
Because he knows the area, he also talks about the effect of wet years and dry years, and how that affects winter and summer temperatures. He has a dry wit, and lovely casual style.
I think that if we have to rely on statistical analysis to “know” whether data was shifted or moved when there is no documentation suggesting it was, all certainty is shot, and any definitive statement about temperature trends in Australia is a joke. — Jo

UPDATED AGAIN #4 — Now with Vukcevics Hale cycle graph of Echuca. and #3 David Archibalds suggestion of the Hale Cycle at work. #2 with Willis Eschenbach’s graph and my thoughts, (see below)
Ian Bryce sent me a striking graph (or two). Looking at the original raw data from Echuca Victoria shows a dramatic cooling trend of nearly half a degree since 1900, and rather than being a siting anomaly, it’s repeated in two towns about 100km away.
Curiously he also finds peaks in the maximums at Echuca that look for all the world like they match the solar cycle. Is it a fluke, or could it be real? If it’s real, what conditions make the solar sun-spot cycle so apparent in Echuca — where its maximum temperatures seemingly peak with each second solar cycle. Can anyone find this signal in other places? — Jo
The area is inland Northern Victoria
Has there been Global Warming or Global Cooling in Echuca
