UK Government overrules council to give go-ahead to fracking

Fracking permission takes a week in Texas but nine years in Britain, as the GWPF’s Dr Benny Peiser points out. Some objectors still claim the technique is unproven despite years of experience in the USA and elsewhere.

Communities secretary Sajid Javid has upheld an appeal made by Cuadrilla in February against the decision by Lancashire County Council to refuse permission to carry out hydraulic fracturing at two sites in the region reports Utility Week.

In a letter to a lawyer representing the drilling company, Javid said it will be allowed to drill and then fracture four exploratory wells at its site on Preston New Road, subject to some conditions.

Wind farms undermine energy security, warns Aussie Government

David Crowe in The Australian reports on the row about renewable energy policies in the wake of the storm that crashed South Australia’s entire state power grid. Phrases like ‘reality check’ and ‘sow the wind, reap the whirlwind’ spring to mind.

The Australian government will confront the states over the ­danger of statewide blackouts at an urgent meeting tomorrow to respond to the outage across South Australia last week, amid a furious political fight over ­whether wind farms helped cause the failure.

The states are being warned that their growing use of renewable energy will make their power networks more vulnerable to outages, leaving Australians at risk of blackouts from any repeat of last week’s ferocious storm.

Are planets setting the Sun’s pace?

Variation in solar activity during a recent sunspot cycle [credit: Wikipedia]

Here we are told that ‘Researchers…are putting forward a new theory’ which may be amusing to Talkshop regulars and others who have been discussing and investigating such matters for years, but – better late than never for the rest of the science world!

The Sun’s activity is determined by the Sun’s magnetic field. Two combined effects are responsible for the latter: The omega and the alpha effect. Exactly where and how the alpha effect originates is currently unknown.

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are putting forward a new theory for this in the journal Solar Physics. Their calculations suggest that tidal forces from Venus, the Earth and Jupiter can directly influence the Sun’s activity.

Many questions regarding the Sun’s magnetic field are still unanswered. “As with the Earth, we are dealing with a dynamo. Through self-excitation, a magnetic field is created from virtually nothing, whereby the complex movement of the conductive plasma serves as an energy source,” says the physicist Dr. Frank Stefani from HZDR.

The Sun’s so-called alpha-omega dynamo is subject to a regular cycle. Approximately every eleven years the polarity of the Sun’s magnetic field is reversed, with solar activity peaking with the same frequency.

This manifests itself in an increase in sunspots — dark patches on the Sun’s surface which originate from strongly concentrated magnetic fields. “Interestingly, every 11.07 years, the Sun and the planets Venus, the Earth and Jupiter are aligned. We asked ourselves: Is it a coincidence that the solar cycle corresponds with the cycle of the conjunction or the opposition of the three planets?” ponders Stefani.

Although this question is by no means new, up to now scientists could not identify a plausible physical mechanism for how the very weak tidal effects of Venus, the Earth and Jupiter could influence the Sun’s dynamo.
Talkshop comment: Unless they came across some of Ian Wilson’s research perhaps?

Strengthening through resonance
“If you only just give a swing small pushes, it will swing higher with time,” as Frank Stefani explains the principle of resonance. He and his team discovered in recent calculations that the alpha effect is prone to oscillations under certain conditions. “The impulse for this alpha-oscillation requires almost no energy. The planetary tides could act as sufficient pace setters for this.”

The so-called Tayler instability plays a crucial role for the resonance of the Sun’s dynamo. It always arises when a strong enough current flows through a conductive liquid or a plasma. Above a certain strength, the interaction of the current with its own magnetic field generates a flow — in the case of the colossal Sun, a turbulent one.

It is generally understood that the solar dynamo relies on the interaction of two induction mechanisms. Largely undisputed is the omega effect, which originates in the tachocline. This is the name of a narrow band between the Sun’s inner radiative zone and the outer areas in which convection takes place, where heat is transported using the movement of the hot plasma. In the tachocline, various, differentially rotating areas converge. This differential rotation generates the so-called toroidal magnetic field in the form of two “life belts” situated north and south of the solar equator.

Booker Exposes Wadhams’ Crackpot Theories

Fool me once, shame on you; fool me twice, shame on me.

Arctic ice scare merchants are fast running out of credibility in the face of the inconvenient – for them – facts.

NOT A LOT OF PEOPLE KNOW THAT

Booker in the Telegraph today:

I know it is only two weeks since I last reported on Arctic ice, but the latest news from that front is even more remarkable. My theme then was those sad climate activists who regularly venture into the polar regions because they have been fooled into thinking that the ice is vanishing but find it so thick that they have to be rushed back to safety. But this week’s focus is on those responsible for fooling them.

For nine years, two professors – Wieslaw Maslowski from California and Peter Wadhams from Cambridge – have been in the forefront of warning that, thanks to runaway global warming, the Arctic will soon be “ice-free”. Their every dire prediction has been eagerly reported by the warmist media, led by the BBC, In 2007 they said this would happen “by 2013”.

In July 2008 The Independent even devoted its…
