Oct. 3, 2019: Solar Minimum is underway, and it’s a deep one. Sunspot counts suggest it is one of the deepest minima of the past century. The sun’s magnetic field has become weak, allowing extra cosmic rays into the solar system. Neutron monitors at the Sodankyla Geophysical Observatory in Oulu, Finland, show that cosmic rays are percentage points away from a Space Age record:

Researchers at the Sodankyla Geophysical Observatory have been monitoring cosmic rays since 1964. When cosmic rays hit Earth’s atmosphere, they produce a spray of secondary particles that rain down on Earth’s surface. Among these particles are neutrons. Detectors in Oulu count neutrons as a proxy for cosmic rays.

As the top panel shows, cosmic rays naturally wax and wane with the 11-year solar cycle. During Solar Maximum cosmic rays are weak; during Solar Minimum they are strong. The Space Age record for cosmic rays was set…

There are many reasons NASA is pursuing the Artemis mission to land astronauts on the moon by 2024: It’s a crucial way to study the moon itself and to pave a safe path to Mars, says Phys.org.

But it’s also a great place to learn more about protecting Earth, which is just one part of the larger Sun-Earth system.

Heliophysicists—scientists who study the Sun and its influence on Earth—will also be sending up their own NASA missions as part of Artemis. Their goal is to better understand the complex space environment surrounding our planet, much of which is driven by our Sun.

An interview with Professor Valentina Zharkova on the effect of solar activity on terrestrial climate – from Conversations That Matter, with Stuart McNish.

The sun is going through a stage known as a solar or Maunder Minimum. This is where the solar activity that ignites solar flares or sun spots has decreased.

It’s a normal cycle and one that has been linked to the mini ice age that lasted more than 50 years starting in the mid-1600s.

Thanks to Ian Wilson for introducing us to his new paper, which is part three of the planned four-part series. The paper can be downloaded from The General Science Journal here. Abstract below.

Abstract

The best way to study the changes in the climate “forcings” that impact the Earth’s mean atmospheric temperature is to look at the first difference of the time series of the world-mean temperature, rather than the time series itself.

Therefore, if the Perigean New/Full Moon cycles were to act as a forcing upon the Earth’s atmospheric temperature, you would expect to see the natural periodicities of this tidal forcing clearly imprinted upon the time rate of change of the world’s mean temperature.

Using both the adopted mean orbital periods of the Moon, as well as calculated algorithms based upon published ephemerides, this paper shows that the Perigean New/Full moon tidal cycles exhibit two dominant periodicities on decadal time scales.

Solar cycle 24 – going, going…

Spaceweather.com

Sept. 23, 2019: Could northern summer 2019 go down in history as “the summer without sunspots”? From June 21st until Sept 22nd, the sun was blank more than 89% of the time. During the entire season only 6 tiny sunspots briefly appeared, often fading so quickly that readers would complain to Spaceweather.com, “you’ve labeled a sunspot that doesn’t exist!” (No, it just disappeared.) Not a single significant solar flare was detected during this period of extreme quiet.

This is a sign that Solar Minimum is underway and probably near its deepest point. For 2019 overall (January through September), the sun has been blank 72% of the time, comparable to annual averages during the century-class Solar Minimum of 2008 (73%) and 2009 (71%). The current Solar Minimum appears to be century-class as well, meaning you have to go…

Obsessing about tiny percentages of trace gases in the atmosphere may be a popular sport in some quarters these days, but it’s an unproductive one.

Political and corporate leaders gathered for the climate week in New York City have urged significant action to fight global warming, writes Dr. Shaviv in the Epoch Times.

But, given the high costs of the suggested solutions, could it be that the suggested cure is worse than the disease?

As a liberal who grew up in a solar house, I have always been energy-conscious and inclined toward activist solutions to environmental issues.

I was therefore extremely surprised when my research as an astrophysicist led me to the conclusion that climate change is more complicated than we are led to believe.

The disease is much more benign, and a simple palliative solution lies in front of our eyes.

This 2017 Chinese study is here.

Below is the Summary — obviously the full info and graphics can be viewed via the link.
– – –
Many studies presented that solar variability does play a significant role in affecting the Earth’s climate change. Almost all of previous studies focused on the effects of solar total irradiation energy.

As the second major source, the solar wind energy flux exhibits more significant long-term variations, but its effect has been rarely concerned. Although the energy content of solar wind energy flux is of 4-5 orders lower than that of irradiation energy, its long-term variation is much more significant.

Sunspots [image credit: NASA]


Here it’s claimed that the model matches the observations, which is surely a good start in any research. With a deep solar minimum now in progress, theorists should have plenty of new data to work with.

For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun’s surface, says Phys.org.

They have observed but been unable to explain why the number of spots peaks every 11 years.

A University of Washington study published this month in the journal Physics of Plasmas proposes a model of plasma motion that would explain the 11-year sunspot cycle and several other previously mysterious properties of the sun.

“Our model is completely different from a normal picture of the sun,” said first author Thomas Jarboe, a UW professor of aeronautics and astronautics. “I really think we’re the first people that are telling you the nature and source of solar magnetic phenomena—how the sun works.”

The Solar Panel Toxic Waste Problem

‘Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants’ – and in some parts of the world recycling rules can be sketchy, or worse.

PA Pundits - International

By Duggan Flanakin ~

For decades, the solar industry benefited from generous federal, state, and local subsidies to increase its footprint. Yet these generous subsidies ignore the costs of disposal of solar panel waste.

Things may be changing. In May 2018, Michael Shellenberger, a Time Magazine “Hero of the Environment” and Green Book Award Winner, wrote in Forbes that the problem of solar panel disposal will explode with full force in two or three decades and wreck the environment because it is a huge amount of waste which is not easy to recycle.

Shellenberger was citing comments, published in the South China Morning Post, from Chinese solar expert Tian Min, general manager of Nanjing Fangrun Materials, a recycling company in Jiangsu province that collects retired solar panels. Tian called his country’s solar power industry “a ticking time bomb.”

This is not really news. The Associated Press had reported in 2013…

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.

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.

Plus: how big will the bite of the ongoing solar minimum be, compared to the last one? We’re due to find out sometime soon.

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.

Omega blocking highs can remain in place for several days or even weeks [image credit: UK Met Office]


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.
