From the Hockey Schtick, via the GWPF, news of a new paper supporting the Svensmark hypothesis:

NEW PAPER CORROBORATES SOLAR-COSMIC RAY THEORY OF CLIMATE
10/04/14 The Hockey Schtick

cloudsA paper published today in Environmental Research Letters corroborates the Svensmark cosmic ray theory of climate, whereby tiny 0.1% changes in solar activity are amplified via the effect on cosmic rays and cloud formation, which in turn may control global temperatures.

The authors find cosmic ray variations due to changes over solar cycles may have as much as 10 times larger effect than previous studies have estimated. The paper also finds that a tiny 0.2C temperature increase increases the cosmic ray induced cloud condensation nuclei by around 50%, thus acting as a natural homeostatic mechanism.

Guest post from Tony Thomas following up the GWPF story from yesterday about the degree to which schoolchildren are being propagandised by climate activist material and teaching practice.

 Climate Catastrophism For Kiddies
by Tony Thomas 9-4-14

kid-polar_bearGet ‘em young and fill their heads with warmist propaganda — that seems to the unofficial motto of Britain’s education establishment, which has just been warned by the Home Secretary that peddling propaganda as fact is a punishable offence

Alarming climate  and eco-activist messages are saturating the British school system, according to a report by noted UK bloggers Andrew Montford and John Shade. On the same  day of the report’s publication, April 8, the response of UK Secretary of State for Education Michael Gove was to warn   teachers they are breaking the law if they fail to provide balanced coverage of climate change and similar issues.

The affair suggests a similar independent inquiry into “climate teaching” in Australian schools would be worthwhile. Anecdotal accounts of brainwashing by activists masquerading as teachers in our primary and secondary schools are legion.

lollianus-mavortiusQuintus Flavius Maesius Egnatius Lollianus signo Mavortius (fl. 330 – 356) was a politician of the Roman Empire. Known as Roman consul Lolliano Mavorzio in the local dialect, an acephalous [headless] statue of Mavortius was discovered in Puteoli, then Pozzuoli (near Naples, Italy) in the C18th. He was Governor of Campania from 328 to 335, comes Orientis from 330 to 336, Proconsul of Africa from 334 to 337, Praefectus urbi of Rome in 342,Consul in 355 and Praetorian prefect of Italy for Constantius II between 355 and 356.

Being a well travelled man who had probably conversed with the scribes of   the Serapeum, had made many naked eye observations of the heavens, and taking a strong interest in the subject himself, he encouraged the senatorial writer Julius Firmicus Maternus to write an astrological essay, the Matheseos libri VIII. It is among the last extensive handbooks of a “scientific” astrology that circulated in the West before the appearance of Arabic texts in the 12th century. According to Firmicus Maternus, the system of horoscopic astrology was given early on to an Egyptian pharaoh named Nechepso and his priest Petosiris. The Hermetic texts were also put together during this period.

Green ‘smear campaign’ against professor who dared to disown ‘sexed up’ UN climate dossier
By David Rose 6-4-14

apocalypse

The professor who refused to sign last week’s high-profile UN climate report because it was too ‘alarmist’, has told The Mail on Sunday he has become the victim of a smear campaign.
Richard Tol claims he is fighting a sustained attack on his reputation by [Bob Ward, director of the Grantham Institute], a leading institution that researches the impact of global warming .
Prof Tol said:

This has all the characteristics of a smear campaign. It’s all about taking away my credibility as an expert.

Prof Tol, from Sussex University, is a highly respected climate economist and one of two ‘co-ordinating lead authors’ of an important chapter in the 2,600-page report published last week by the UN Intergovernmental Panel on Climate Change (IPCC AR5 WGII).
He has been widely criticised by green campaigners after he claimed that the much shorter ‘summary for policymakers’ [SPM] – hammered out in all-night sessions between scientists and government officials over a week-long meeting in Yokohama, Japan – was overly alarmist.
In his view, the summary focused on ‘scare stories’ and suggestions the world faced ‘the four horsemen of the apocalypse’.

Why the IPCC Report Neglects the Benefits of Global Warming 
It needs catastrophe scenarios. 

 

josh_raymondo_scrThe IPCC’s Working Group II, tasked with assessing the risks and impacts of climate change, could have chosen to make amends for its previous effort in 2007, which was widely panned for bias and numerous errors. Such was the outcry over the 2007 report that the Dutch parliament ordered the country’s Environmental Assessment Agency to carry out an audit. It found that the working group was dismissive of the potential benefits of climate change, and it criticized the group’s process for being insufficiently transparent. Similarly, a report by the InterAcademy Council, chaired by Princeton’s Harold Shapiro, noted that the group’s Summary for Policymakers had been criticized “for various errors and for emphasizing the negative impacts of climate change.” The summary contained many statements that “are not supported sufficiently in the literature, not put into perspective, or not expressed clearly,” the Council said.

There is a new open access paper published in Environmental Research Letters by Yannick Peings and Gudrun Magnusdottir entitled ‘Forcing of the wintertime atmospheric circulation by the multidecadal fluctuations of the North Atlantic ocean’. It’s another blow to the ‘bad winter weather is caused by us wicked humans’ doom mongers such as Met Office chief scientist Julia Slingo.

wpid-PRP-Censured.jpgOver the last five years there’s been a revival of an old hypothesis which suggests that the motion of the planets around the Sun modulates its output, and that variation in the Sun’s output affects the Earth’s weather and in the longer term, shifts in regional and global climate. This revival has been most visible here in the blogosphere, where ideas can be kicked around with less professional reputational risk, and a faster exchange and development of concepts and narratives can take place. There has also been a steady trickle of papers published in the scientific literature relevant to the theory, and these have been championed and denigrated by bloggers on both sides of the issue.

Naturally, in the overheated atmosphere of the climate debate, the second part of the idea is especially controversial, with the Intergovernmental Panel on Climate Change telling us that human emitted ‘greenhouse gases’ are the primary driver of global warming since the middle of the last century. They also say the Sun’s variation has very little effect on climate change. An IPCC author recently took exception to our special edition on the theory and got the journal we published it in axed. The first part of the idea is controversial too, as the received wisdom from most mainstream solar physicists is that the planets are too small and too far from the Sun for their motion to affect it. They are sure that the Sun runs an internal ‘dynamo’ (Babcock & Leighton) and ‘chronometer’ (Dicke) which accounts for the observations of its cyclic variations that have been made over the centuries.

Gergis findings re-surface – the Hockey Stick lives!

By Tony Thomas 31-03-2014

josh-gergisHello again Hockey Stick, goodbye global Medieval Warming Period.

These are the conclusions of a multi-proxy 1000-year climate reconstruction published today (March 31) in Nature Climate Change, by Dr Raphael Neukom of the Oeschger Centre at the University of Bern, and Dr Joelle Gergis of the University of Melbourne.

Dr  Neukom   summed up for a University of Melbourne press release:

The study showed the ‘Medieval Warm Period’, as identified in some European chronicles, was a regional phenomenon. 

During the same period, temperatures in the Southern Hemisphere were only average. Our study revealed it was not a common climate event that many people have previously assumed.

The paper claims that in 99.7 percent of the results, the warmest decade of the millennium occurred after 1970.

The press release says,“And surprisingly, only twice over the entire past millennium have both hemispheres simultaneously shown extreme temperatures.

One of these occasions was a global cold period in the 17th century; the other was the current warming phase”.”[1]

H/T to Gerry Pease for alerting me to this paper from last year by Steinhilber and Beer which lays out a solar prediction from their analysis of their reconstruction of solar activity from proxy data.

Prediction of solar activity for the next 500 years
Friedhelm Steinhilber1 and Jürg Beer1
Received 18 May 2012; revised 18 February 2013; accepted 2 March 2013.

Recently, a new low-noise record of solar activity has been reconstructed for the past 9400 years by combining two 10Be records from Greenland and Antarctica with 14C fromtree rings [Steinhilber et al., 2012]. This record confirms earlier results, namely, that the Sun has varied with distinct periodicities in the past. We present a prediction of mean solar magnetic activity averaged over 22 years for the next 500 years mainly based on the spectral information derived from the solar activity record of the past. Assuming that the Sun will continue to vary with the same periodicities for the next centuries, we extract the spectral information from the past and apply it to two different methods to predict the future of solar magnetic activity.
