Greens seem to have an obsession with dimming the sun, otherwise known as starving plants of sunlight and stripping away our disease resistance.
Why dimming the Sun would be an effective tool in the fight against climate change

Lecturer in Earth Sciences, UCLIt’s becoming increasingly clear that we will fail to meet our climate goals. We were already at 1.26°C of warming in 2022 and are on track to blow through 1.5°C in the mid-2030s. Research even suggests that current climate policy will lead to more than 2.5°C of warming by the end of this century.
Warming of this magnitude would devastate vulnerable communities and ecosystems around the world. It’s time we consider something radically new that could stop climate change in its tracks.
After powerful volcanic eruptions, like Tambora (Indonesia) in 1815 and Pinatubo (Philippines) in 1991, global temperatures dipfor a few years. Major eruptions create a hazy layer of microscopic particles in the upper atmosphere that last for several years, dimming the Sun temporarily. We could copy this effect to fight climate change.

I don’t get how educated people can convince themselves deliberately dimming the sun is a good idea, when there is an abundance of evidence that it would be a very bad idea.
Last time the sun was dimmed significantly by a series of major volcanic eruptions, the Eastern Roman Empire almost failed. The dimming of the sun during the dark ages had multiple severe adverse consequences for human health.

Abstract
The large volcanic eruptions of AD 536 and 540 led to climate cooling and contributed to hardships of Late Antiquity societies throughout Eurasia, and triggered a major environmental event in the historical Roman Empire. Our set of stable carbon isotope records from subfossil tree rings demonstrates a strong negative excursion in AD 536 and 541–544. Modern data from these sites show that carbon isotope variations are driven by solar radiation. A model based on sixth century isotopes reconstruct an irradiance anomaly for AD 536 and 541–544 of nearly three standard deviations below the mean value based on modern data. This anomaly can be explained by a volcanic dust veil reducing solar radiation and thus primary production threatening food security over a multitude of years. We offer a hypothesis that persistently low irradiance contributed to remarkably simultaneous outbreaks of famine and Justinianic plague in the eastern Roman Empire with adverse effects on crop production and photosynthesis of the vitamin D in human skin and thus, collectively, human health. Our results provide a hitherto unstudied proxy for exploring the mechanisms of ‘volcanic summers’ to demonstrate the post-eruption deficiencies in sunlight and to explain the human consequences during such calamity years.

Quite apart from the starvation caused by reduced crop yields, reduced metabolic availability of Vitamin D in today’s world would be a big problem. Vitamin D is a major contributor to immune resistance to influenza and Covid, people who don’t receive enough Vitamin D are more likely to require emergency medical assistance.
Does vitamin D deficiency increase the severity of COVID-19?
E Kenneth Weir, professor of medicine,A Thenappan Thenappan, associate professor of medicine,B Maneesh Bhargava, associate professor of medicine,C and Yingjie Chen, professor of physiologyD
ABSTRACT
The severity of coronavirus 2019 infection (COVID-19) is determined by the presence of pneumonia, severe acute respiratory distress syndrome (SARS-CoV-2), myocarditis, microvascular thrombosis and/or cytokine storms, all of which involve underlying inflammation. A principal defence against uncontrolled inflammation, and against viral infection in general, is provided by T regulatory lymphocytes (Tregs). Treg levels have been reported to be low in many COVID-19 patients and can be increased by vitamin D supplementation. Low vitamin D levels have been associated with an increase in inflammatory cytokines and a significantly increased risk of pneumonia and viral upper respiratory tract infections. Vitamin D deficiency is associated with an increase in thrombotic episodes, which are frequently observed in COVID-19. Vitamin D deficiency has been found to occur more frequently in patients with obesity and diabetes. These conditions are reported to carry a higher mortality in COVID-19. If vitamin D does in fact reduce the severity of COVID-19 in regard to pneumonia/ARDS, inflammation, inflammatory cytokines and thrombosis, it is our opinion that supplements would offer a relatively easy option to decrease the impact of the pandemic.

We also have evidence from modern times that volcanic eruptions impact crop yields.
Estimating global agricultural effects of geoengineering using volcanic eruptions
Jonathan Proctor, Solomon Hsiang, Jennifer Burney, Marshall Burke & Wolfram Schlenker
Abstract
Solar radiation management is increasingly considered to be an option for managing global temperatures1,2, yet the economic effects of ameliorating climatic changes by scattering sunlight back to space remain largely unknown3. Although solar radiation management may increase crop yields by reducing heat stress4, the effects of concomitant changes in available sunlight have never been empirically estimated. Here we use the volcanic eruptions that inspired modern solar radiation management proposals as natural experiments to provide the first estimates, to our knowledge, of how the stratospheric sulfate aerosols created by the eruptions of El Chichón and Mount Pinatubo altered the quantity and quality of global sunlight, and how these changes in sunlight affected global crop yields. We find that the sunlight-mediated effect of stratospheric sulfate aerosols on yields is negative for both C4 (maize) and C3 (soy, rice and wheat) crops. Applying our yield model to a solar radiation management scenario based on stratospheric sulfate aerosols, we find that projected mid-twenty-first century damages due to scattering sunlight caused by solar radiation management are roughly equal in magnitude to benefits from cooling. This suggests that solar radiation management—if deployed using stratospheric sulfate aerosols similar to those emitted by the volcanic eruptions it seeks to mimic—would, on net, attenuate little of the global agricultural damage from climate change. Our approach could be extended to study the effects of solar radiation management on other global systems, such as human health or ecosystem function.

Why do learned people keep cheerleading this crazy geoengineering idea, when the risks so obviously outweigh any possible benefits?
The rationale for geoengineering is that a few degrees of warming will have adverse consequences on food availability, which would justify taking these kinds of risks.
But farming is simply not that sensitive to temperature.
Take Maine potatoes. Potatoes are grown in Maine, a place not known for its tropical weather, but they also grow well in subtropical Bundaberg, a major food producing region in Australia. The only adjustment Aussie farmers applied to grow cold weather food crops in a tropical climate like Bundaberg, is extreme early planting – they plant the potatoes in Fall. The potatoes don’t know our mild tropical winters are actually winter, so they grow vigorously throughout the winter months, and are ready to harvest by Spring, before the tropical Summer heat withers and kills them.
My point is very few plants have such a narrow range that a few degrees of warming would impact yields. Cooling can be a problem, in marginal Northern agricultural regions cooler weather can shorten the growing season to such an extent that crops do not mature in time, but warming is much easier to accomodate. If the climate warms, farmers will simply plant their crops a little earlier in the season, maintaining the optimal temperature range for their growing cycle, or they will switch to other crops if the warming is sufficient that new and more profitable crops become viable.
Global warming, even if it continues, will not negatively impact food availability.
The abundance of evidence that solar geoengineering on any kind of scale would have dire health consequences, and is not justified by any genuine risk to our food supply, should rule out this foolish idea for vandalising our global climate.
Another case of the Green Blob assuming the Little Ice Age was some kind of golden age. If one thinks war, plague, and famine are good things, yes.
Since many Greens say that the world’s population should decline to 1 to 2 billion people, they would say that war, plague and famine are good things.
What could possibly go wrong?
Way back when, it was commonly believed that a comet or asteroid struck the earth approximately 65 million years ago. The smoke from the fires and the debris ejected high into the atmosphere blocked so much sunlight that most of the plant life died, followed by most of the surface life, including the dinosaurs.
Nowadays, we know this was wrong because it was climate change that caused this mass extinction. Climate change, as we well know, causes everything bad that happens.
The moral of the story is climate change is more serious than any possible geoengineering foul-up. We’re much too clever as a species to screw things up, particularly if we put the climate activists in charge. The computer models prove it.
What could possibly go wrong? Just watch the film Snowpiercer.
Makes sense. I think the prerequisite for running for the Presidency- is that the person must be a climate activist. 🙂
“I don’t get how educated people can convince themselves deliberately dimming the sun is a good idea…”
Well they have form.
These are the same people who think reducing CO2 in the atmosphere, the very thing essential for abundant plant growth, is a good idea.
hmmmm…. they’re starting to seem…. Satanic!
dim the sun- starve the plants- impoverish a greatly reduced human race!
Led by Baal Gates?
The Sun has been dimming on its own since about 1960. Because the oceans can hold so much heat, it takes decades to show up as land temperatures.

They’re on a suicidal spectrum
“”Wynn Alan Bruce, 50, from Boulder, Colorado, who self-immolated on Friday – when the world marked Earth Day – suffered critical injuries and was airlifted to hospital, where he died, a police spokesperson said.
Those who knew Bruce, who had managed a portrait photo studio in Boulder, say he was protesting against inaction on the climate crisis.””

All for nothing
The People’s Republic of Boulder…
One less idiot voting for the Socialists.
Bruce tried in 2017 — no reason known, even to his father who attempted to get his son into mental health council. There is a wiki page on this person:
Self-immolation of Wynn Bruce
If he wanted a renewable future he could reincarnate. Come back as a mealworm and my grankids will eat him . A sad case of murder in the first degree Greta Thunberg, Joe Biden Al Gore in the dock
Dimming the sun is a good thing? Maybe if one serves and seeks to curry favor with The Prince of Darkness. Plus make all those acres of solar farms ever less reliable and efficient.
Let’s bring back that good old SO2 air pollution blocking sunlight from the 1970s, and call it climate geoengineering.
Thanks for so many good articles Mr. Worrall — you are the best climate and energy reporter I know of, and I read and read over 20 climate and energy articles every day of the year … including every article you write.

A far easier way would be to go back to using bunker fuel on all shipping 🙂
The hubris of the warmunists has a natural end play to it … if humans can control Earth’s climate in a negative way (warming?), then ipso facto, humans can also control Earth’s climate in a positive way (cooling?).
Whatever it is that the warmunists want to do, it will fail, fantastically so, with massive amounts of blowback and unintended consequences. Of course, the opposite of hubris is humility, and the warmunists are totally devoid of humility. They believe they are the Masters of the Universe … or at least, if the rest of us would just get out of their damn way, they would be.
If GOVERNMENT could control the planet temperature, they would likely increase it by 2 or 3 degrees to make the planet more hospitable to humans, provide more farmland, longer growing seasons, more tropical paradise to retire to, more rainfall for vegetation, all those good things….
“Warming of this magnitude would devastate vulnerable communities and ecosystems around the world. It’s time we consider something radically new that could stop climate change in its tracks.”
They get crazier by the day. Like, as if they haven’t already considered extremely radical fantasies? Stop the monster in its tracks? I know a shrink- I’ll have to ask him what they use to treat psychotics. But maybe I won’t- since he’s a climate nut job. 🙂
This was a big idea back in the 1970s—it was called “nuclear winter”.
Global cooling, nuclear winter, acid rain, the ozone hole, and global warming were all running in the press at nearly the same time.
Throw enough mud at the wall and finally some of it will stick.
The ozone “holes” were over the poles, where for half the year they get no sunlight, no sunlight that’s involved both in breaking apart and putting ozone together. Without sunlight half the year it’s natural for there to be less polar ozone.
Aside from that, how is a “hole” over the Arctic and Antarctic supposed to have any effect on the amount of solar UV hitting the surface in Los Angeles, Sydney, St. Petersburg etc?
The usual propaganda:
“We were already at 1.26°C of warming in 2022 and are on track to blow through 1.5°C in the mid-2030s.”
And this “fact” (repeated over and over and over and over and over and over again) is known to a hundredth of a Kelvin, sure it is.
Global average air temperature tells very little about climate.
“
ResearchBogus computer modeling even suggests…”Edited for TRVTH.
And who are “we”?
Adding the +/- 3°C wouldn’t make it so scary or scientific sounding.
“Volcanic dust veils from sixth century tree-ring isotopes linked to reduced irradiance, primary production and human health”
No doubt they’re confident that they know the year of some tree rings- but I have my doubts- at least, to the accuracy that the article implies.

Dendrochronology is quite accurate and useful.
Treemometers, not so much.
Sure, but when you get back that far- I’m skeptical. I’ll have to read your link. They’ll have to have a continuous record of tree rings unless you h ave a tree that is 1,500 years old.
We are being systematically lied to:

Or something like that.
The worry is that he is paid to teach other people when he is quite barking. And ‘Earth Sciences’? Smells bad to me.
The rich plan on making trillions from climate change spending which is estimated at $US200 trillion to stop warming by 2020 by Bloomberg’s green research team. Other estimates are similar.
Didn’t Kerry just make one of these “smells bad” comments at COP-28..
Geo engineering is just an unfortunate symptom of climate derangement syndrome. Despite this readily available research, it’s challenging to convince people about the true severity of global warming. It boggles my mind that people don’t take it upon themselves to conduct research and question the acceptance of highly dubious “scientific” claims.
I think any serious attempt to dim the Sun’s light would be a cause for war among nations.
All the “people” advocating for this stupidity should be herded into an abandoned mine and left in the dark for 6 months. Problem solved.
We just have a dimmed sun, by a weather phenomenon usually called fog.
Or clouds !
the vast majority of deaths from COVID had very low levels of vitamin D that the body produces from exposure to sunlight – so killing people may be the real goal
Funny thing about vitamin D is that the FIRST mention of use of it by Fauchi was in September, 9 months after the start of the China Virus talk. I always hopped that, during a committee meeting where he was a witness, someone would ask him why he hated “people of color” so much as to NOT mention the need for them to take D during his first press conference. Then follow up with “Was it more important for to you to make TRUMP! look bad by ensuring more POC die under his watch, their deaths serving the greater good?”
BTW, as a diabetic I take 6000 iu of D a day. I also spend SOME time outdoors, but being at altitude much of the time, I wear long pants, long sleeve shirts and hats to keep from getting burned. 20 minutes at 8600 ft can get you in the summer.
There are some good videos of presentations on the topic of vitamin D.
Bruce Hollis is a good one.
https://www.youtube.com/watch?v=QrU1yrmNIqc
The long and the short of it: Vitamin D isn’t just helpful in treatment of prostate cancer, it helps shrink an enlarged prostate which is not cancerous.
Despite what many pre-medical professionals are still taught, it is extremely difficult to over-dose on vitamin D. We have evolved with much higher levels than most people maintain today, due to insufficient skin exposure to UV. A constant exposure/dose is important because of the pharmacodynamics of production/dosage versus the long term storage which is effectively unavailable on a short term basis.
Plus, it is far more important for many cellular processes than was originally understood. Medical science is way behind the curve in terms of what would-be Physicians are taught in medical school textbooks.
My wife and I started taking 4000iu of vitamin D daily shortly after the start of Covid.Apart from a short period, approx 1 overlapping week each, where we had a flu like illness which tested positive for Covid, we were fine. We continue to take it daily.
People should be careful about taking vitamin D.
I had a doctor that perscribed 10,000iu a day for me. I, being me, decided that was too much, and instead took about 5,000iu a day.
My doctor retired and my new doctor told me to stop taking vitamin D as I had toxic levels of vitamin D in my system!
And that was with only taking half of what was prescribed for me.
So make sure you need vitamin D before you take any.
I found out vitamin B-12 is also important.
I had a little numbness in my feet, and I kept seeing commercials on tv about peripheral neuropathy, which is where your feet go numb from complications of diabetes.
So, I was thinking maybe I had pre-diabetes or something and went to the doctor and got the lab work done and it showed my blood sugar was right in the middle of the normal range and diabetes was not an issue.
But it turns out that a lack of vitamin B-12 can cause similar symptoms and I was low on my vitamin B-12, and I’ve been taking supplements for a few months now, and my foot numbness is slowly going away.
A yearly doctor’s visit is worth its weight in gold.
Remdesivir did not make sense because it was known to cause kidney failure and yet it was and is still an “approved” treatment.
Health care organizations in their scientific brilliance have concluded that Covid-19 is one of a few viral diseases known to attack kidneys.
Between the autumnal and vernal equinoxes the NHS in the U.K. advise vitamin D supplements of 400 IU/ 10 microgrammes per day. Between the vernal and autumnal equinoxes most people obtain sufficient vitamin D from the sun.
“Good sources of vitamin DFrom about late March/early April to the end of September, most people should be able to make all the vitamin D they need from sunlight.
The body creates vitamin D from direct sunlight on the skin when outdoors.
But between October and early March we do not make enough vitamin D from sunlight. Read more about vitamin D and sunlight.
Vitamin D is also found in a small number of foods.
Sources include:
Another source of vitamin D is dietary supplements.
In the UK, cows’ milk is generally not a good source of vitamin D because it is not fortified, as it is in some other countries.”
The attached picture is a list of EU countries and their vitamin D supplement policies.
“What happens if I take too much vitamin D?Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). This can weaken the bones and damage the kidneys and the heart.
If you choose to take vitamin D supplements, 10 micrograms a day will be enough for most people.
Do not take more than 100 micrograms (4,000 IU) of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years.
Children aged 1 to 10 years should not have more than 50 micrograms (2,000 IU) a day. Infants under 12 months should not have more than 25 micrograms (1,000 IU) a day.
Some people have medical conditions that mean they may not be able to safely take as much. If in doubt, you should consult your doctor.
If your doctor has recommended you take a different amount of vitamin D, you should follow their advice.
You cannot overdose on vitamin D through exposure to sunlight. But always remember to cover up or protect your skin if you’re out in the sun for long periods to reduce the risk of skin damage and skin cancer.””
“Don’t take more than 4000 IU per day as it may be harmful ”
NONSENSE !
DO A LITTLE RESEARCH !
How much can a person get from sunlight!
Hint … it is a LOT more than 4000 IU !
We do not get enough vitamin D in the UK. We are constantly running at a deficit because of the latitude/angle of the sun. Ask yourself this – why did our ancestors skin colour change from our previously dark brown skin colour to the pale colour we have now in the northern latitudes? To get as much sunlight as possible into our bodies and it still isn’t enough – everybody should be taking 500-1,000 units daily, more the further north you live. I have a vitamin D deficiency so currently take around 3000 units every few days (10,000 units a week, roughly) because, without it, my vitamin D levels drop to just above the danger level.
information that is decades out of date
I’ve said it before, I’ll say it again. There is every scientific reason to believe that solar geo-engineering can quickly return the earth’s climate to that of the Little Ice Age. And to do it for pennies on the dollar in comparison with Net Zero, which is a fantasy in any case.
The great majority of climate activists in the environmental NGO’s, in government, and in the climate change industrial complex will never support solar geo-engineering as a solution.
The activists will spend money on solar geo-engineering research just to claim they are pursuing every alternative for addressing climate change. But they will never allow it to be put into actual practice. For the simple reason that if solar geo-engineering ends global warming, the climate change gravy train ends with it.
The Marshal Islands are in a life or death struggle against climate warming…they want $35 billion to survive….can you help them?
I would, but I’m in a life and death struggle myself, currently in the living part.
“Browns” versus “Greens”
I am always frustrated with the term “Green”, such as “Green New Deal”. It is a scientific fact any reduction in atmospheres Carbon Dioxide (CO2) would limit plant/tree growth and vitality.
These CO2 reductions would definitely reduce the “Green” and increase the “Brown” on our planet.
I therefore call it the “Brown New Deal” and those supporting as “Browns” and not “Greens”. My non-woke friends are typically amused and in agreement, while woke friends are typically not amused.
By the way, the term “Brown” has second meaning, although crude, when describing this destructive ideology.
Everything these Greens do will turn the world Brown.
Use Brown versus Green
I can with total certainty say that Peter Irvine is stark raving mad. Why anyone would listen to him is beyond me.
See my comment above. Peter,Irvine isn’t stark raving mad. He is a member of the climate change industrial complex and is selling further research into solar geo-engineeriing as his niche business inside climate change academia. He makes a good living pursuing this research.
If someone wants to return the earth’s climate to that of the Little Ice Age, there is little question solar geo-engineering can get the job done.
That said, Peter Irvine has to know that climate activists will never allow solar geo-engineering to be put into actual practice. For the simple reason that if solar geo-engineering ends global warming, the climate change gravy train ends with it.
Why do they want to do it? They know the CO2 crisis warming meme has been brutally falsified by sceptics and Narure herself. Their anomaly forecasts in the heyday of of 1990 for 25 yrs forward proved to be 300% higher than observations. Ditto every other weather metric – floods, fires, droughts, arctic ice – nothing alarming or new.
How do we know that the Dark Side itself knows that they have been horribly wrong? By their behavior and actions. They moved the goalposts of the period of manmade warming back from 1950 to 1850 (when pop. at~1m) to bankroll 0.6°C of natural warming from the LIA. They began fiddling temperatures, now automated to adjust T daily cooling the past and warming the present in fractions if a degree. They didn’t need to do that when the actually believed it would be 5-7 C higher by 2100 with seas rising 19-12 ft.
The frenzy to enact horrible legislation and get geoengineering done is to be able to say they prevented the worst of the harm by their actions. It’s to get ahead of the parade to nowhere. They know otherwise that the untold millions of deaths caused by Climate Policy by the destruction of economies, rampant inflation and destruction of food security will be properly laid at the feet of the globalist billionaire shotcallers – Gates, Schwab, and other WEF gangsters, western governments and the academic useful fools. Yeah, they should be scared.
The Vitamin D3 information is from 2020. The idea was forcefully put in blogs (Jo Nova, others) back then, but this article would have been very helpful had the U.S. CDC promoted it. If they did, I missed it. Seems they were busy convincing folks Ivermectin was dangerous.
From the post: We were already at 1.26°C of warming in 2022 [Peter Irvine, Univ. College-London]
I’m sure he rounded up. The actual number was 1.257839°C. 😏
I moved from Cleveland, Ohio to Los Angeles, California many years ago.
Although it was 20F warmer, it was still comfortable.
After about 5 years I moved back to Cleveland and still like the weather here although in Cleveland you have to bundle up in the winter.
In winter, in LA the rain can be almost constant and hard for days on end. In Cleveland we have colder snowy days and warmer days in the winter. The snowy and rainy days are both about as irritating.
1.5C is nothing. It’s even less than the average difference in temperature between day and night.
“Why do learned people keep cheerleading this crazy geoengineering idea, when the risks so obviously outweigh any possible benefits?”
Because the vast majority of the highly credentialed are not truly learned, they are indoctrinated group-thinkers. They cannot do critical thinking or math.
Yes, if the goal is to control the weather and therefore the climate, then that goal is certain to be missed thankfully. If we were able to control our climate then the last person we would want making the decisions is a lunatic such as this oblivious lecturer who thinks we can and should block out the sun which gives makes all life on Earth possible. Why does it seem that the closer a person gets to higher education and the longer they stay there the lower their capacity for logic and critical thinking?
If we ever get to the point of actually controlling climate I suggest we let farmers, miners and primary producers who live in the real world make the decisions.
