Solar panel road [image credit: Wattway]


The rotting leaves didn’t help, says ScienceAlert. Neither did the local tractors. Solar panels should be angled towards the Sun anyway, but that kills the whole road idea.

In July, the French daily newspaper Le Monde reported that the 0.6-mile (1 kilometre) solar road was a fiasco.

In December 2016, when the trial road was unveiled, the French Ministry of the Environment called it “unprecedented”. French officials said the road, made of photovoltaic panels, would generate electricity to power streetlights in Tourouvre, a local town.

But less than three years later, a report published by Global Construction Review says France’s road dream may be over.

H/T The GWPF

The researchers say: “We have detected no evidence of human influence”, so the implications of the observed long-term natural variation are clear enough. But some reading between the lines may be needed here, due to a few of the usual nods towards man-made warming theory that climate researchers feel they have to make to survive these days.

Research sheds light on 500-year Chinese climate cycle and suggests global cooling could be on the way, reports the South China Morning Post.

A new study has found winters in northern China have been warming since 4,000BC – regardless of human activity – but the mainland scientists behind the research warn there is no room for complacency or inaction on climate change, with the prospect of a sudden global cooling also posing a danger.

The study found that winds from Arctic Siberia have been growing weaker, the conifer tree line has been retreating north, and there has been a steady rise in biodiversity in a general warming trend that continues today.

It appears to have little to do with the increase in greenhouse gases which began with the industrial revolution, according to the researchers.

They call it ‘the world’s most ambitious project‘. Mind-boggling expenditure if it ever gets built. The solar city aspect of the plan gets panned here.

The riches of Silicon Valley have enabled some extravagant and quixotic projects, but they’ve got nothing on what oil money can do, says MNNOFA News.

A new report from The Wall Street Journal shares some of the proposals for Saudi Arabia’s biggest megaproject yet: a city built in the desert named Neom, where robots will outnumber humans and hologram teachers will educate genetically-enhanced students.

The details are stunning. It’s a mixture of dystopian fiction (AI surveillance cameras everywhere!) and childish imaginings (let’s build a robot dinosaur park!). Taken together, the plans remind of you what a dedicated nine-year-old can achieve in Minecraft. Yes, the scale and ambition are impressive, but it’s not like you could do this in real life, right?

Cloud seeding? Robot servants? A fake moon!? Sure, why not.

Sunspots [image credit: NASA]


This looks timely as predictions of the possibly imminent – or not – start of solar cycle 25 jockey for position, so to speak. Is there a new and better method here?

In a pair of new papers, scientists paint a picture of how solar cycles suddenly die, potentially causing tsunamis of plasma to race through the Sun’s interior and trigger the birth of the next sunspot cycle only a few short weeks later, reports EurekAlert.

The new findings provide insight into the mysterious timing of sunspot cycles, which are marked by the waxing and waning of sunspot activity on the solar surface.

While scientists have long known that these cycles last approximately 11 years, predicting when one cycle ends and the next begins has been challenging to pin down with any accuracy. The new research could change that.

In one of the studies, which relies on nearly 140 years of solar observations from the ground and space, the scientists are able to identify “terminator” events that clearly mark the end of a sunspot cycle.

July 16, 2019: Note to astronauts: 2019 is not a good year to fly into deep space. In fact, it’s shaping up to be one of the worst of the Space Age.

The reason is, the solar cycle. One of the deepest Solar Minima of the past century is underway now. As the sun’s magnetic field weakens, cosmic rays from deep space are flooding into the solar system, posing potential health risks to astronauts.

NASA is monitoring the situation with a radiation sensor in lunar orbit. The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) has been circling the Moon on NASA’s Lunar Reconnaissance Orbiter spacecraft since 2009. Researchers have just published a paper in the journal Space Weather describing CRaTER’s latest findings.

Climate of Sophistry

Roy Spencer published an article today stating that I am incorrectly ranting about the fraud of flat Earth theory making its way into modern physics via climate science.  I analyze his statement and expose that climate science truly is indeed flat Earth theory: it is baked into the mathematics!

‘The coronal heating problem in solar physics relates to the question of why the temperature of the Sun’s corona is millions of kelvins higher than that of the surface. Several theories have been proposed to explain this phenomenon but it is still challenging to determine which of these is correct’ — Wikipedia.

It’s one of the greatest and longest-running mysteries surrounding, quite literally, our sun—why is its outer atmosphere hotter than its fiery surface?

University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA’s Parker Solar Probe, says Phys.org.

In roughly two years, the probe will be the first manmade craft to enter the zone surrounding the sun where heating looks fundamentally different than what has previously been seen in space.

This will allow them to test their theory that the heating is due to small magnetic waves travelling back and forth within the zone.

Atmospheric blocking is a well-known weather phenomenon. The report below says ‘In recent years, the scientists observed a clear increase of these patterns’. But scientists have also reported a 20 year decline in solar magnetic fields and solar wind micro-turbulence levels. Coincidence, or possibly not?

Record breaking heatwaves and droughts in North America and Western Europe, torrential rainfalls and floods in South-East Europe and Japan – the summer of 2018 brought a series of extreme weather events that occurred almost simultaneously around the Northern Hemisphere in June and July, says IOP Publishing.

These extremes had something in common, a new study published today in Environmental Research Letters by an international team of climate researchers now finds.

The events were connected by a newly-identified pattern of the jet stream encircling the Earth. The jet stream formed a stalled wave pattern in the atmosphere, which made weather conditions more persistent and thus extreme in the affected regions.

The same pattern also occurred during European heat waves in 2015, 2006 and 2003, which rank among the most extreme heatwaves ever recorded. In recent years, the scientists observed a clear increase of these patterns.

If the global warming nightmare was to happen, solar and wind systems simply don’t work in high-heat environments. So why are activists pushing them, asks Climate Change Dispatch?

Everything, and I mean everything about the man-made global warming movement is rotten to the core, says Dr. Joel Adams.

Tens of thousands of our own brave and brilliant scientists, as well as websites such as Climate Change Dispatch, are fighting the good fight against the climate change fraud every day. It’s a fight we are working hard to win.

I just completed a 435-page book on the subject of climate change fraud and the people and motivations behind it.

I discovered that as bad as the scientific fraud is, the motivations behind it turned out to be worse. These motivations are to put it in a few words: money and a political totalitarian power grab by the political Left.

Coronal rain [image credit: NASA’s Solar Dynamics Observatory]


We’re told “The physics is literally the same” for the Earth’s rain and the Sun’s plasma showers, except that on the Sun the scale is much bigger than the entire Earth.

It’s one of the most enduring mysteries of the Sun: why the superheated surface of this great ball of glowing plasma is actually cooler than its outer atmosphere, called the corona.

Scientists now have a new explanation for this hotly debated topic says ScienceAlert, and the answer was hidden in a strange solar phenomenon that’s never been observed quite like this before: a deluge of plasma rain falling within newly discovered magnetic structures called Raining Null Point Topologies.

This looks significant, pointing directly at solar influences on climate patterns. The researchers found evidence that atmosphere-ocean coupling can amplify the solar signal, having detected that wind anomalies could not be explained by radiative considerations alone.

An international team of researchers from United Kingdom, Denmark, and Germany has found robust evidence for signatures of the 11-year sunspot cycle in the tropical Pacific, reports Phys.org.

They analyzed historical time series of pressure, surface winds and precipitation with specific focus on the Walker Circulation—a vast system of atmospheric flow in the tropical Pacific region that affects patterns of tropical rainfall.

They have revealed that during periods of increased solar irradiance, the trade winds weaken and the Walker circulation shifts eastward.

Another of the sun’s secrets comes into view.

The sun’s magnetic field is ten times stronger than previously believed, new research from Queen’s University Belfast and Aberystwyth University has revealed.

The new finding was discovered by Dr. David Kuridze, Research Fellow at Aberystwyth University, reports Phys.org.

Dr. Kuridze began the research when he was based at Queen’s University Belfast and completed it when he moved to Aberystwyth University in 2017. He is a leading authority on the use of ground-based telescopes to study the sun’s corona, the ring of bright light visible during a total eclipse.

The author writes in his 40-page document: ‘This report is not meant to be an exhaustive representation of all the published papers related to a solar influence on Earth’s climate, but aims to give a clear presentation of the current knowledge on the link between solar activity and climate.’

Where does cosmic ray variation fit into the ‘big picture’ of solar influences on the Earth?

The Next Grand Minimum

I am still studying this paper but wanted to share and get your feedback

Executive Summary

Over the last twenty years there has been good progress in understanding the solar influ- ence on climate. In particular, many scientific studies have shown that changes in solar activ- ity have impacted climate over the whole Holocene period (approximately the last 10,000 years). A well-known example is the existence of high solar activity during the Medieval Warm Period, around the year 1000 AD, and the subsequent low levels of solar activity during the cold period, now called The Little Ice Age (1300–1850 AD). An important scientific task has been to quantify the solar impact on climate, and it has been found that over the eleven- year solar cycle the energy that enters the Earth’s system is of the order of 1.0–1.5 W/m2. This is nearly an order of magnitude larger than what would be…

Pairs or multiple systems of stars which orbit their common center of mass. If we can measure and understand their orbital motion, we can estimate the stellar masses.

How does this work? The two massive stars in question are orbiting each other at a distance of 180 AU (astronomical units), six times greater than that of Neptune to the Sun. Each orbit may take nearly 600 years.

Scientists from the RIKEN Cluster for Pioneering Research in Japan, Chalmers University of Technology in Sweden and the University of Virginia in the USA and collaborators have made observations of a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system, reports Phys.org.

While it is known that most massive stars possess orbiting stellar companions it has been unclear how this comes about—for example, are the stars born together from a common spiraling gas disk at the center of a collapsing cloud, or do they pair up later by chance encounters in a crowded star cluster.

Solar tsunami can trigger the sunspot cycle

Something else for solar theorists to ponder. The researchers say: ‘We have demonstrated here a physical mechanism, the solar tsunami, which gives birth to the new cycle’s sunspots precisely within a few weeks from the cessation of old cycle’s spots.’

According to the model, the next sunspot cycle can be expected to begin in 2020, says The Hindu.

It is believed that the “solar dynamo” — a naturally occurring generator which produces electric and magnetic fields in the sun — is linked to the production of sunspots.

What kick-starts the 11-year sunspot cycle is not known. Now, a group of solar physicists suggests that a “solar tsunami” is at work that triggers the new sunspot cycle, after the old one ends.

Quiet sun [image credit: NASA]


In which we are informed that the Maunder Minimum was ‘an incident’, warming is due to ‘climate change’, and solar cycle 25 may not start until 2020.

Some fear that we could be heading to another Little Ice Age, but scientists say that’s unlikely, reports CBC News.

The sun is quiet … very quiet. In February, for the first time since August 2008, the sun went an entire month without any sunspots.

What does this mean for Earth?

Maybe there’s some military angle to this. As the report says, it ‘will be difficult and costly’. Capturing the sun’s power will be cloud-free, but when transmitting to the ground the clouds are still there.

China wants to put a solar power station in orbit by 2050 and is building a test facility to find the best way to send power to the ground, reports MACH (NBC News).

As the green energy revolution accelerates, solar farms have become a familiar sight across the nation and around the world.

But China is taking solar power to a whole new level. The nation has announced plans to put a solar power station in orbit by 2050, a feat that would make it the first nation to harness the sun’s energy in space and beam it to Earth.

These types of tech ‘breakthroughs’ tend to have a low survival rate in the real world, so we await any developments – or not.

Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air, reports Science Business.

After ten years of development, the panel can now produce 250 litres per day – a world record, according to the researchers.

Twenty of these solar panels could provide electricity and heat for one family for an entire winter.

What effects might this have on so-called ‘climate change’? The next few years could be interesting as lower solar activity displaces the higher activity of the 1990s and early 2000s.

Feb. 21, 2019:Cosmic rays in the stratosphere are intensifying for the 4th year in a row. This finding comes from a campaign of almost weekly high-altitude balloon launches conducted by the students of Earth to Sky Calculus. Since March 2015, there has been a ~13% increase in X-rays and gamma-rays over central California, where the students have launched hundreds of balloons.

neutronsandxrays2

The grey points in the graph are Earth to Sky balloon data. Overlaid on that time series is a record of neutron monitor data from the Sodankyla Geophysical Observatory in Oulu, Finland. The correlation between the two data sets is impressive, especially considering their wide geographic separation and differing methodologies. Neutron monitors have long been considered a “gold standard” for monitoring cosmic rays on Earth. This shows that our student-built balloons are gathering data of similar quality.

Why are cosmic rays increasing? The short answer is “Solar…
