Michael Kruger at German skeptic site Science Skeptical here writes about how solar energy indutry in Germany has disintegrated spectacularly.
What follows are 4 charts that show us some shocking trends, and how in reality the German solar industry has seen a bloodbath that can be rated as one of the worst in a long time. The reality is that Germany’s green revolution is far from being a model for the world.

The solar activity in the past millennia can only be reconstructed from cosmogenic radionuclide proxy records in terrestrial archives. However, because of the diversity of the proxy archives, it is difficult to build a homogeneous reconstruction. All previous studies were based on individual, sometimes statistically averaged, proxy datasets. Here we aim to provide a new consistent multi- proxy reconstruction of the solar activity over the last 9000 years, using all available long-span datasets of 10Be and 14C in terrestrial archives.

The star that keeps us alive has, over the last few years, been almost free of sunspots, which are the usual signs of the Sun’s magnetic activity. Last week [4 September 2009] the scientific team behind the satellite SOHO (Solar and Heliospheric Observatory) reported, “It is likely that the current year’s number of blank days will be the longest in about 100 years.” Everything indicates that the Sun is going into some kind of hibernation, and the obvious question is what significance that has for us on Earth.
If you ask the Intergovernmental Panel on Climate Change (IPCC) which represents the current consensus on climate change, the answer is a reassuring “nothing”. But history and recent research suggest that is probably completely wrong. Why? Let’s take a closer look.

Dr. Willie Soon is an independent solar physicist at the Harvard-Smithsonian Center for Astrophysics who has been studying the Sun and its influence on the Earth’s climate for more than a quarter of a century. A short while ago, he had a conversation with Mr. Grégoire Canlorbe, an independent journalist who is also vice president of the French Parti National-Libéral (“National-Liberal Party,” conservative, nationalist, and free-marketist). Here Dr. Soon speaks for himself.
Canlorbe: You say polar bears are far less endangered by global warming than by environmentalists dreading ice melt. Could you expand?

Evidence of a Cycle 25 sunspot found
In our previous post: Solar activity crashes – the Sun looks like a cueball,
Our resident solar physicist, Dr. Leif Svalgaard commented and provided a link to something reported by his colleagues, something that likely would not have been possible without the fantastic solar observations of NASA’s Solar Dynamic Observeratory (SDO).
It seems a small sunspot has been observed, that has the opposite polarity of cycle 24 sunspots.

Right now, the sun is a cueball, as seen below in this image today from the Solar Dynamics Observatory (SDO) and has been without sunspots for 10 days. So far in 2018, 61% of days have been without sunspots (…)

Huge hole over 400,000 miles long (700,000 kilometers) is 55 times wider than the Earth A wide hole in the sun’s atmosphere is facing Earth and spewing a stream of solar wind toward our planet. Estimated time of arrival: April 9th. In this extreme ultraviolet image from NASA’s Solar Dynamics Observatory, we see not only the […]

People have asked about the tools that I use to look for any signature of sunspot-related solar variations in climate datasets. They’ve wondered whether these tools are up to the task. What I use are periodograms and Complete Ensemble Empirical Mode Decomposition (CEEMD). Periodograms show how much strength there is at various cycle lengths (periods) in a given signal. CEEMD decomposes a signal into underlying simpler signals.
Now, a lot of folks seem to think that they can determine whether a climate dataset is related to the sunspot cycle simply by looking at a graph. So, here’s a test of that ability. Below is recent sunspot data, along with four datasets A, B, C, and D. The question is, which of the four datasets (if any) is affected by sunspots?

Periods of extreme cold winter weather and perilous snowfall, similar to those that gripped the UK in a deep freeze with the arrival of the ‘Beast from the East’, could be linked to the solar cycle, pioneering new research has shown.
A new study, led by Dr Indrani Roy from the University of Exeter, has revealed when the solar cycle is in its ‘weaker’ phase, there are warm spells across the Arctic in winter, as well as heavy snowfall across the Eurasian sector.
The research is published in leading journal Scientific Reports, a Nature Publication, on Tuesday, 20 March 2018.

So, you still don’t believe small changes in solar activity can significantly affect climate? You know a very cold period during the Little Ice Age coincided with the Maunder Minimum, but you have heard that the Little Ice Age could have had other causes, like volcanoes. You have been told repeatedly that since 1980 solar activity has been decreasing while global temperature has been increasing, so it can’t be the Sun.
Not so fast. There is a vested interest in climate change not being due to the Sun, as the Sun can’t be taxed or prevented from doing what it does. A further problem is that solar physicists have no clue about how the Sun can show centennial or millennial periodicities. As they prefer to talk about what they know, they reject such periodicities, even though we have evidence in cosmogenic records (14C in tree rings and 10Be in ice cores).
And if I tell you that little changes in the Sun have a disproportionate effect on climate you won’t believe me. You shouldn’t believe me. You shouldn’t believe anybody. Science is not about believing. Religion is about believing. So, I propose that you prove to yourself what effect little changes in the Sun have on climate.

L’ Alliance solaire internationale est une initiative lancée par l’Inde et la France lors de la COP21 qui vise à « augmenter de manière significative la production d’électricité solaire » dans les 121 pays situés en totalité ou en partie entre les tropiques du Cancer et du Capricorne (des pays en voie de développement pour la grande majorité).
En juin 2017, l’Alliance solaire internationale indiquait que 33 pays avaient signé son accord-cadre et que 6 l’avait ratifié : l’Inde, la France et 4 territoires insulaires (Fidji, Maurice, Nauru, Tuvalu)(5). Il est nécessaire que 15 pays ratifient cet accord-cadre pour qu’il entre en vigueur. En mars 2018, l’Alliance solaire internationale a été officiellement lancée à New Delhi, en présence d’Emmanuel Macron et d’une vingtaine de dirigeants d’Asie, d’Afrique et d’Océanie.
Le gouvernement indien s’est engagé à abriter le secrétariat de l’Alliance solaire internationale pour une durée de 5 ans (jusqu’en 2021).

According to the United Nations Intergovernmental Panel on Climate Change (UN-IPCC) and computer modeling, the Sun’s role in modern-era climate change checks in at somewhere slightly above nothing.
And yet it is increasingly evident that more and more scientists across the globe do not take the position that the Sun’s influence on climate change is negligible.
In 2016 and 2017, for example, over 250 papers (see here and here) linking the Sun to climate changes were published in scientific journals.

The sun is the natural source of heat and light for our planet. Without our sun, the earth would be a cold dead planet adrift in space. But the sun is not constant. It changes and these subtle changes affect the Earth’s climate and weather.
At the end of solar cycle 23, sunspot activity declined to a level not seen since the year 1913. [Comparing Yearly Mean Total Sunspot Numbers1]
The following was observed during the solar cycle 24: (…)

As mentioned yesterday, scientists now believe we could be heading into a 50 year period of reduced solar activity similar to what happened in the mid-17th century, which could lead to a drop in global temperatures of “several tenths of a degree Celsius”.
As has been pointed out, climate is a far more complex matter than climate scientists admit, and one about which we still know very little.
Whether a Maunder-like Minimum will happen again in the next few years, and whether it will have the effect claimed, remain to be seen.
But there is considerable evidence that the Maunder Minimum did coincide with a sharp fall in temperatures across the NH, as NASA show above.
