The geological factual basis is clear: Fluctuations in solar activity significantly influenced the development of the climate throughout the history of the Earth.
Today’s IPCC is clueless. With its simplistic approach, the IPCC is not able to reproduce the documented climate fluctuations of the past. The gross fundamental errors aren’t of any help at all for the most powerful computers. In the search for additional links in the sun-climate-impact, Willie Soon of the Harvard-Smithsonian Center for Astrophysics and David Legates of the College of Earth, Ocean, and Environment at the University of Delaware came across an exciting relationship. In a mutual study that appeared in the February 2013 Journal of Atmospheric and Solar-Terrestrial Physics, the scientists were able to show a relationship between solar activity fluctuations and the temperature gradient between the North Pole and the equator over a timescale of multiple decades.

Parts of European academia have obviously lost their marbles, as one apparently crazed professor has called for the death penalty for people who disagree with the IPCC dogma. Call it an interesting case of budding extreme fanaticism.
Dire tones from the University of Graz: music professor calls for the death penalty for climate science dissenters
By Dr Sebastian Lüning and Prof Fritz Vahrenholt(Translated/edited by P Gosselin)
Over the last 30 years huge progress has been made in natural and environmental protection. Exhaust today is being intensively scrubbed, waste-water is being cleaned and energy is being used ever more efficiently. We can consider ourselves fortunate to be living in a time and place where environmental hazards today are hardly a threat to the population.
But what started as a successful and well intentioned environmental movement, now appears to have careened totally out of control. The movement has not done itself any favors by hitching itself to the ideologically led fight against the supposed climate catastrophe. The climate catastrophe scenarios announced 10 years ago by a very convinced IPCC have not come to pass. In stark contradiction to the theoretical prognoses, global temperatures have not risen in 16 years. Over the last decade, the sea level rise has not accelerated, and weather extremes are well within the range of natural variability. A look at the real, measured data and the paleo-climatological reconstructions tells us there is no alarm.

Face it, challenging a dogma takes real courage and character. There’s the real risk of being ridiculed, marginalized – even criminalized.
And history has often shown that sometimes you even have to wait way beyond your death before society wakes up and appreciates that you had been right all along.
Yesterday I wrote about Dr. Hans Labohm‘s report, soon to appear in E&E. In it he describes the growing sceptic movement in Europe and how it is succeeding in forcing a very much unwanted debate on the cause of today’s climate change. It’s a debate that unfortunately governments, academia and media would very much prefer to skip altogether.

Although the silence that has spread over the mainstream media and “climate community” has been deafening, skeptic blogs on the other hand have been stepping in earnestly to inform the public on what the climate is really doing. The blogosphere has been ablaze over the last few days.
In Germany the media has been dead silent on the news that warming has stopped. There’s a simple reason for that: In Europe, good news is bad news.
Sebastian Lüning and Fritz Vahrenholt have published their take on the official HadCRUT confirmation that there’s been no warming since even before Michael Mann’s infamous hockey stick fabrication was first released.

Dr. Sebastian Lüning’s and Prof Fritz Vahrenholt’s website has an article today.
No North Atlantic Phenomenon: Medieval Warm Period and the Little Ice Age Found in the Andes
(Translated from the German by P Gosselin)
The Little Ice Age and the Medieval Warm Period are North Atlantic phenomena, so claim Stefan Rahmstorf and other IPCC colleagues. Globally, they were compensated for by other regions, and so we should not worry too much over these local climate anomalies. And least of all, we should not get the idea the sun may have had something to do with it. It is only a pure coincidence that the sun happened to be so strong during the Medieval Warm Period. Also, the low solar activity during the Little Ice Age also means nothing. Moreover, it is also completely meaningless that the second half of the 20th century was one of the most active episodes for solar activity in the last 10,000 years.
In September 2012 in the journal Climate of the Past Discussions a new study on the climate development of the last 1000 years in the Andes Mountains in South America was published. A group led by Marie-Pierre Ledru of the Institute of Sciences of Evolution of Montpellier studied pollen from a sediment core extracted from a marsh in Ecuador. They compared the climate development there with data from other areas taken in the mountains range.

Reconstruction of precipitation amounts for the edge of the Tibet Plateau. The bars on the chart depict prominent weak phases of solar activity, which correspond to Om = Oort Minimum; Wm = Wolf Minimum; Sm = Spörer Minimum; Mm = Maunder Minimum; Dm = Dalton Minimum)
. Figure from: Sun & Liu (2012)
Yet another study has appeared in the Journal of Geophysical Research, this one looks at the precipitation history on the Tibet Plateau of the last 1000 years.
Geologist Dr. Sebastian Lüning and chemist Prof. Fritz Vahrenholt have written a summary of this paper, which I’ve translated in the English.

Comparison of solar activity (blue curve) and the Asian climate development (green curve, delta 18O of a stalagmite in a Chinese cave) for the last 9000 years (both curves normalized). One clearly sees a good agreement between the two curves, which stgrongly suggests a significant climate impact by the sun.

The IPCC thinks the sun plays nary a role on climate and that anthropogenic factors explain almost the entire warming since 1850.
It’s been completely ignored that Gerard Bond was able to show more than 10 years ago that the last 10,000 years have been characterized by a global temperature roller coaster that runs up and down in sync with solar activity (Bond et al. 2001).

P. Gosselin: There’s been lots of disingenuous criticism from the CO2 end-of the world warmists and Armageddonists aimed at Fritz Vahrenholt’s and Sebastian Lüning’s new best selling skeptic book Die kalte Sonne. Much of it attacking Svensmark’s theory of solar amplification via cosmic rays.
Again. none have really read the book, they simply repeat the same old debunked arguments.
Henrik Svensmark hits back at the skeptics at the Die kalte Sonne site (scroll down to the English version):
Prof. Henrik Svensmark, Danish National Space Center (Copenhagen) on the criticism aimed at his solar amplifier via cosmic rays:
"Some people, including your critic Florian Freistetter on ScienceBlog, seem to think that physics is a democratic process and what matters is to count how many papers favour or disfavour each hypothesis. That of course is nonsense. All that really signifies is the evidence from observations and experiments, and how a theory stands up to attempts to falsify it. Remember Einstein’s comment on the pamphlet Hundert Autoren gegen Einstein (1931) – “If I were wrong, one would be enough”.

Hell has finally frozen over! Fritz Vahrenholt, one of the fathers of Germany’s environmental movement who has headed the renewable energy division of RWE, that country’s second largest utility company, has co-authored a new blockbuster book with geologist/paleontologist Sebastian Luning announcing that the climate catastrophe heralded by the U.N.’s Intergovernmental Panel on Climate Change (IPCC) has been called off. Titled “The Cold Sun: Why the Climate Disaster Won’t Happen”, it raises a man-made blizzard of icily numbing challenges to IPCC competence in general, and to their exaggerated attributions of CO2 greenhouse warming influence in particular.
Such charges from a prominent socialist and former global warming doctrine apostle have really taken the alarmist community by storm…and their symbolic timing as Germany has been experiencing its worst cold snap in 26 years made the message even more dramatic. Three of Germany’s most widely read news publications, Bild, Der Spiegel, and Die Welt immediately took notice, releasing skeptical climate science articles in their print and on-line editions.
The initial Bild article titled “The CO2 Lie” addressed “What the IPCC of the U.N. doesn’t tell you”, and then asks, “…what if the IPCC is wrong? Can we really blindly trust these experts? Are they really independent?” They then conclude, “The phenomenal prognoses of heat from the IPCC are pure fear-mongering.” Part 2 titled “There Hasn’t Been Any Global Warming In 12 Years!” emphasizes that CO2 is not that potent of a gas, and that a doubling would lead to only a 1.1°C temperature increase. Yet the IPCC fudges the models so that they produce a much higher increase because of the assumed water-vapor amplifier. This assumption is really on shaky ground.
