CO2, the Chinese virus and the profiteers of doom

By Christopher Monckton of Brenchley

By the time you read this, the monthly Mauna Loa CO2 concentration will probably have been published. The profiteers of doom have been delighted by the global Chinese-virus lockdown, which many of them would like to be permanent.

As John Christy reported here yesterday, in March the UAH dataset maintained by Roy Spencer shows the second-biggest month-to-month drop in global mean lower-troposphere temperature since the record began in December 1978.

But, as Anthony Watts pointed out in a comment, the fall in temperature owes nothing to a decline in CO2 concentration, whether or not caused by the lockdown. The keepers of the Mauna Loa record agree with him:


Let us assume that there has indeed been a 25% decline in our sins of emission, and that it will persist until the pandemic ends in 18 months’ time, as some epidemiologists have predicted. Let us also assume that there will be a further 0.2 ppmv reduction in CO2 concentration for each of the next 18 months. Then the CO2 concentration will have fallen by a dizzying 3.6 ppmv.

Maybe. For IPCC says CO2 persists in the air for about 125 years, in which event nothing we do this century will make much difference to CO2 concentration.

However, just for fun, let us imagine that over the next 18 months the concentration does indeed fall by 3.6 ppmv. Let us work out how much global warming the tens of trillions that the Chinese-virus lockdown has cost us will have bought.

In March, the Mauna Loa CO2 concentration C0 was 414.5 ppmv. At the end of the pandemic, then, C will be 410.9 ppmv. Let us pretend that, as the Thermageddonites wish, it would not bounce back to where it is now, but that the pandemic will reduce all subsequent CO2 concentrations, whatever they might otherwise have been, by 3.6 ppmv. Let us also pretend that the reduction will occur immediately, rather than in 125 years’ time.

The coefficient k in the CO2 forcing equation is 5 (derived from Andrews et al. 2012). The Planck or zero-feedback sensitivity parameter P is 0.3 K W–1 m2 (ibid.). The system-gain factor G from feedbacks is the absurdly exaggerated 3 imagined by IPCC et hoc genus omne (it is in truth more like 1.2, which means there is no climate “emergency”, but let us be generous to the cult).

Eq. (1), informed by these quantities, gives the global warming reduction arising from the drastic emissions reduction caused by the pandemic, on the generous assumption that it is a permanent reduction.


Gee wow golly-gosh! Mirabile dictu!! One whole twenty-fifth of a degree!!! Hold the front page!!!!

All the numbers fed into Eq. (1), as well as the equation itself, are “mainstream science”. And that’s the whole problem with this global warming nonsense. The cost of mitigation is as large as the benefit is small. Even if we stop emitting CO2 altogether by 2050, if IPCC is right the corresponding small reduction in global temperature will take 125 years to come through.

For that reason alone, even before allowing for official climatology’s glaring error in the definition of temperature feedback, an error in which IPCC intends fraudulently to persist in its Sixth Assessment Report even though it has been told in writing that its definition is incorrect, it makes no economic sense to do anything whatsoever about global warming except to let it happen, adapt to it and enjoy the sunshine.

Will someone tell world followers?

Today’s graphs show a continuing decline in active cases, but the mean daily compound growth rate in cumulative deaths remains high. The reason is that at this stage in the pandemic the case fatality rate is very high. Take the United States.

There have been 66,000 reported deaths at the time of writing, but the Centers for Disease Control concluded a couple of days ago that, based on excess mortality data, deaths have been under-reported by about 15%. So there have really been about 76,000 deaths.

Assuming a mean 17 days from case report to death, the deaths reported now arose on or about April 13, when there were 715,000 cases. So the U.S. case fatality rate, at a rough estimate, is about 10.5%, compared with a global 7.5% (and more like 24% in the UK).

But there are now 1.131 million cases in the United States. Allowing for the current gentle slowing in both reported cases and deaths, even if there were no more cases (and at present there are 30,000 new ones a day), by mid-June and perhaps sooner there will have been 125,000 U.S. deaths associated with the Chinese virus – and counting.

To put this in context, the CDC has estimated that the past winter’s flu season caused somewhere between 20,000 and 62,000 deaths. Already the Chinese-virus deaths have exceeded the high-end estimate within just a few weeks. Unfortunately, there are many more deaths to come.

Are we living out a tragedy or a comedy? Modern, instant mass communication has made possible, perhaps even unavoidable, mass hysteria, mass interest, mass concerns about many various issues. All these issues (of which you will find examples in whatever you read, see or hear in the media, in films or on radio) are about sex, food and and fear of enemies – humankind’s eternal centres of concern.

At present we are all consumed with fear of a very ordinary, not even particularly dangerous, infectious illness (this suddenly took over from the equally panicky fear of climate change– remember Greta Thunberg?).

One of the most influential novels ever written was Cervantes’ tale about Don Quixote, the illustrious Spanish gentleman who thought himself great and courageous and rode out in search of enemies to practice his valour on. Finding none, he attacked windmills. He was very sincere and certain he was right – likewise you will find no end of thoroughly sincere, intelligent people who are completely convinced that the world’s battle to conquer this virus is wholly justifiable.

Over the 400 years since this novel was written people have been arguing whether Cervantes meant it to be a comedy or a tragedy. Therein lies its greatness.

Imagine the mass hysteria you could have had if the fact that this was biolab leak and possibly a bioweapon had been know as it hit the West back in February!

CofB should have stopped with the CO2 calculation which he does at least seem to roughly understand.

To put this in context, the CDC has estimated that the past winter’s flu season caused somewhere between 20,000 and 62,000 deaths.

Last years seasonal flu was a generally mild flu year. A better “context” would be 2017/18 which was a bad flu season.

CDC seems rather coy about publishing an estimation for that year but does say this:

Nationally, mortality attributed to P&I [pneumonia and influenza] exceeded 10.0% for four consecutive weeks, peaking at 10.8% during the week ending January 20, 2018.

So IF CofB’s estimated CFR of 10.5% is about right, that places COVID-19 on a par with a bad flu year.

He has sadly, after briefly flirting with legible png formatted graphs, now gone back to fuzzy, illegible jpeg images and expecting folks to download his PowerPoint presentation. That’s probably my fault for reminding him that I suggested png 3 weeks ago in my list of helpful suggestions to his first post.

My personal belief is if we calculate mortality based on total cases, this virus is less deadly than the flu. We won’t know for sure until we get accurate data. By many accounts, deaths are overestimated. People who were never tested should not be included. People who recovered from Covid-19 but later died of something else should not be included.

But I suspect we should be calculating the death for the entire population. The death count may be much higher.

But we should keep these numbers in perspective. The vast majority of the population are not at high risk. Yes, people under 60 with no known corbidity factors are dying, but these are a small percentage of Covid-19 deaths.

To which, my answer is, No! They will not tell them, neither will they listen.

I think Phil was joking.

I absolutely agree, the use of the term “climate denier” is wrong for two reasons:
1. It’s pure poison, clearly designed to sound like “holocaust denier”.
2. It’s completely false. Sceptics do not deny the reality of climate change, that would be ridiculous. Ironically an important sceptical argument is that the climate is always changing.

Another irony: if you think about it, the Mannian hockey stick really is climate denial. The whole point of that fraudulent “science” was to show that there was no significant climate change until the 20th century. The Medieval Warm Period and the Little Ice Age were wiped away – or “got rid of” to quote an infamous email – as if they had never existed. Now if that isn’t climate change denial I don’t know what is!

Paul Johnson-
Even if the satellites give you the resolution you want, that isn’t going to prove anything regarding the relationship between CO2 concentrations and fossil fuel emissions. We would really need to see many months – probably a year or two- of data at 25% emission reduction to be able – perhaps – to discern how this might be modulating the huge natural exchanges of the gas that utterly dwarf the emissions themselves. The balance of opinion, even on the sceptical side, is that it does have this effect, but demonstrating it by this unintended experiment is going to be difficult.

For the same reason, the Mauna Loa team’s statement that “most of the emissions come from urban areas, so that it may be easier to see the effect downwind of cities” is also quite irrelevant and, indeed, misleading.

May 2, 2020 11:21 pm

Just as error, deceit, and manipulation of temperature leads to the nonsense that “we live in a warming world”, the Covid 19 deaths are apparently subject to the same mendacities.
Mr. O’keefe’s Project Veritas has come up with some pretty solid information that deaths are attributed to Covid 19 simply because it improves the greedy grab for money.

I have not confirmed the truth of this story relayed to me yesterday, but I’ll put it out there anyhow for possible consideration as truthful: A nurse at a retirement-living complex got sick. I don’t know where she went to be assessed, but the story, as related to me, is that she was refused a COVID-19 test, but given a diagnosis of “probably COVID-19”.

And I continue to see people everyday — the mask-wearing pod people — completely misusing their face coverings, … some ignorantly, others in defiance (i.e., only wearing them when management is looking). So, lots of people generally are NOT using face masks properly, even if masks could have a marked effect. This is why, I think, the original recommendation was that apparently healthy people should not wear masks. Many people end up risking contaminating themselves by re-breathing contamination on the mask that they themselves have put there or have failed to properly remove, before putting the mask on again.

It has turned into a big show — a circus.

Masks reduce the amount of droplet dispersion FROM infected Individuals by up to 80%…which would otherwise be deposited on surfaces everywhere or inhaled by others directly (up to 10 feet away) from coughs or sneezes.

The biggest downside is that the masks collect viruses from droplets by filtration of the air. If the mask is touched with the hands while the viruses are still viable and then the hands touch the face, viruses can be introduced into the eyes or the respiratory system.

So especially if you are sneezing and coughing (during which times YOU SHOULD NOT go out into public spaces) a mask should be worn. But remove it without touching the mask part…then wash your hands before touching anything else (turn on the spigot before removing the mask).

When N95’s become widely available, they should be used by hair dressers and barbers and others in constant contact with the public. Be ready for a “respiratory workout”. Up to 80 extra calories an hour is expended in just sucking air through some high efficiency masks. “Weight loss mask” infomercials should be expected soon.

Reply to  DocSiders

In theory, the mask should work, as you say, but human behavior is NOT going along with this strict method of handling the mask. Many people simply are NOT doing it correctly — they have no clue.

What if a person is NOT symptomatically “infected”? — does such a person harbor a viral load of sufficient size to expel it from their lungs in sufficient quantity to cause a contamination issue?

Where is the virus now on a contaminated mask that the wearer mishandled?– lingering on the outside of the mask? — in line with the breathing of the mask’s wearer? — possibly getting encased withing micro-droplets or repeated moist breath, now ready to be slingshot off the mask’s fibers into the air once again, from the pressure of air during conversation or just breathing normally?

I’m not convinced that just any old mask will reduce initial droplet dispersion, as you say. Most common fabrics have spaces between the woven threads that are far larger than the virus. When a portion of the droplets containing the virus hits threads, what are the actual dynamics of the droplets after impact? What is the cumulative effective of repetitive droplet/mask collisions over a two-hour time span, in a real-world setting? — a setting where the masks are NOT handled under pristine, lab-controlled guidelines?

The studies that I have read on masks never quite commit to the level of certainty that would offer the assurance that most popular accounts have prevailed in communicating. I see a lot of “may”, “might”, “need more research”, “unknown” … in the wording, and yet the conclusions of such studies seem to contradict this uncertainty by erring on the side of hope in their final statements.

I see no reason for asymptomatic people to walk around like pod people, with symbolic erasures of their individual voices and identities captured in a further symbolic display of compliance with a decree that robs their choices and freedoms to make independent judgments.

Smokers can make an individual choice to light up, with little regard for people thirty feet away who are forced to endure the drifting residue of their exhalations, while people are criticized for exercising freedom to make similar choices regarding unnatural coverings that restrict normal breathing and conversation.

It’s hard enough to understand some cash-register operators in stores, as they speak, and now you put a mask over their faces AND place them behind a plastic barrier, … to further distort their speech, making communication unreasonably more difficult at a point of sale. It’s ridiculous. If we are that afraid to interact, then either shut down the world entirely, everybody avoid everybody else, collapse into a black hole of economic suicide, … or just get back to living.

If you CHOOSE not to interact with people, then fine, that’s your choice. If you CHOOSE to wear a mask, … again fine. If you choose to go to work, to take the risk of driving, walking under a dangling tree limb, among a hoard of people who forgive each other for engaging in habits that give them lung cancer, heart disease, obesity, diabetes, etc., then fine.

My choice is not to wear a mask, and not to be afraid of other people not wearing masks, and to go about living, without constant fear of dying.

Not good enough.
It is well known that airborne droplets can infect people through their eyes, so Glasses are also needed along with gloves.
Don’t believe the bull about not wearing masks and gloves. I provide a simple example about no mask and gloves.
You are in contact with airborne virii, they settle on your face, nose, lips and eyes as well as on yours hands from touching objects.
They tell you to just wash your hands when you get home, but not your face which could be covered in virii.
You wash your hands touch your face and immediately re-infect your hands and if anyone else touches your face, ie with a cheek or lip kiss, they are also infected.
With your face covered by a mask and glasses there is very little of your face to be infected.
You take off your glasses and mask, deposit any shopping etc in the house and then remove the gloves and wash both hands & face.
If you are using the car remove a glove to open doors, boot etc and then remove them and place in the boot otherwise you have to wipe down everything you touch inside the car.
Put the gloves back on to deposit shopping etc in the house and then remove them and wash hands & face.
It requires thought to do everything necessary and stay safe wearing them, but if your life depends on it it is not that hard.

Those wearing PPE for 8-12 hours have a real problem to remember all of that the whole time, that is why face visors as well as a mask are essential.

Significance of the numbers makes the alarm. Exponential rate of change is important because it can make tolerable numbers significant.

Current rough numbers from worldometers does not justify (IMHO) drastic actions. People under 65 should go safely back to work. Daily deaths in the World are about 5 000, UK 500 and Sweden 50. Last two weeks of the latter two look stable. Multiple these with 400 (=365 in one significant number) we get 2 000 000 (0,03%), 200 000 (0,3%) and 20 000 (0,2%). Of course we assume daily deaths to decline.

The monthly mean CO2 level from Mauna Loa as reported by Scripps/NOAA shows the same Northern Hemisphere Growth season sponsored rise over 2019 as all the previous years do : (414.50/411.97 ppm). The industrial shutdown has had no measurable effect on the CO2 cycle as the amount of CO2 that is manmade is only 4% of Nature’s grand effort. The annual variation cycle of CO2 level is about 5/6 ppm and peaks after the NH growing season and bottoms after the SH growing season. The present temperature slide is not driven by any fall in CO2 levels. It is driven by something else, as yet undefined. The trees continue to enjoy the increased CO2 levels but do not approve of the lowering temperatures but are at least, for them, it is offset by the increased CO2 nutrient.

Thanks Tesdorf for the update.

I had an email discussion with Monckton about 11 or 12 years ago, where I insisted on 5% human contribution to the CO2 increase. Monkton agreed with me, but stated that it was difficult to prove, so he reckoned it was more feasible to state that all or most of it comes from human’s fossil fuel burning.

If it can be proven that the lock-down has significantly reduced the consumption of fossil fuel, it appears to me that we now have a confirmation of the 3 to 5%.

A question I have always wondered about. How much of the CO2 comes from human respiration? I have never seen this mentioned but, as the population increases, so will the CO2 output. Is it of any significance or it is so small as to be inconsequential? Doubling the population must double the output.

About 3 billion tonnes annually, but it’s good CO2 because its converted plant material, just like the Methane we produce. This different from the methane and CO2 produced by the animals we eat because it means the GHG gases they produce are in fact produced twice. This is clear evidence for becoming Vegan and ploughing up the grassland currently being used to produce meat.

Not sure about the actual numbers.
However, termites are said to be the most significant land based CO2 producing animal.
With respect to humans: Humans convert about 100W of energy in our body. Much of this energy transformation releases CO2. Additionally we transform around 1000W or so via mostly fossil fuel, wind turbines, etc., which all produce significand amounts of CO2 and comfort.
There are really so many CO2 sources – we are and live in a carbon world, a world the Greens do not want us to be part of.

I’ve been curious for some time regarding the residence time of atmospheric CO2. I have read/heard of claims anywhere from 7 years to 200,000 years, with the IPCC figure being 125 years. I recently read somewhere that, based on measurements of atmospheric CO2 with Carbon-14 resulting from nuclear testing in the 1950’s, the half-life of CO2 in the atmosphere is 16 years. However, I have no knowledge of the veracity of that claim.

So, can any of the WUWT readers/contributors offer any cogent insight into the residence time of CO2? At this point it seems to me that this is just another facet of climate that we just don’t understand very well, and that such claims are largely just conjecture.

Reply to  Dennis Kelley
May 3, 2020 6:06 pm

This was my understanding as well, based on previous research I’ve done. I know that early on it was widely accepted that residency time was probably over 100 years. There are still people saying this, but the newer information I’ve found in the past is what you said. I would love to see if anyone here has knowledge of any newer studies.

Reply to  Dennis Kelley

Dennis Kelley ,

There is a lot of confusion on what the residence time means.
The official formula is:
residence time = mass in the atmosphere / throughput
or mass / input
or mass / output
As long as input = throughput = output, which is true within a few %.
For the current atmosphere that is 830 GtC (as CO2 mass in the atmosphere) and a throughput of ~150 GtC/year (mainly seasonal) thus gives:
830 GtC / 150 GtC/year = 5.53 years.

That is all about exchanges of CO2 molecules between reservoirs, whatever the sources, and mainly temperature driven. That doesn’t change the amount in the atmosphere at all, as long as inputs equal outputs.

The average ocean surface temperature gives a quite stable dynamic equilibrium between atmosphere, oceans and vegetation of about 290 ppmv for the current average sea surface temperature.
If some source (humans, volcanoes) emit more CO2, the CO2 pressure (pCO2) in the atmosphere increases and less CO2 is emitted by the oceans from the upwelling zones near the equator and more is absorbed in the cold sinking waters near the poles. It is that difference which removes CO2 mass out of the atmosphere. The amounts are in direct ratio with the extra pCO2 in the atmosphere above the equilibrium.
The formula for a linear response then is:
e-fold decay rate (tau) = cause / effect
tau = extra CO2 pressure / net sink rate
For the year 2010, that gives:
tau = 110 ppmv / 2.15 ppmv/year = 51.2 years

Thus two different decay rates are involved: the residence time which describes the fate of an individual molecule in the atmosphere (thus the isotopic composition) and the decay rate for any extra CO2 pressure above equilibrium (whatever the cause).

The IPCC uses the Bern and similar models, which has several separate decay rates towards different reservoirs (oceans, vegetation,…), but also implies that a large part of the sinks get saturated, thus assuming that large parts of our emissions (as mass, not the original molecules!) remain in the atmosphere for hundreds to thousands of years.
That is only true for the ocean surface, not for the deep oceans or vegetation. Until now, the decay rate still is the same as 60 years ago, no sign of saturation visible…

Carbon-14 is a different story. In principle, the excess decay rate would be about the same as for the bulk of CO2 (mostly 12CO2 and a small % of 13CO2). But there is a problem: what goes into the deep oceans is the isotopic composition of today, what comes out of the deep oceans is the composition of ~1000 years ago, long before any huge human influence.
That makes that in 1960, at the peak of the 14CO2 from the bomb tests some 97.5% of all sinking 12CO2 returned the same year out of the deep, but only 45% of the amount of 14CO2.
That makes that the excess 14CO2 decay rate was much faster than for any excess 12CO2…

Hope this helped a little…

“As John Christy reported here yesterday, in March the UAH dataset maintained by Roy Spencer shows the second-biggest month-to-month drop in global mean lower-troposphere temperature since the record began in December 1978.”

This stuff is just silly. No, JC did not report that. He reported the second biggest drop in temperature over a two month period, in the Northern Hemisphere, not global. That is a really contrived “record”.

But of course these fluctuations are not caused by CO₂ variation. Whoever said they were? The NH lower trop temp went up to the Feb peak, then went down (a little faster). None of that variation had anything to do with CO₂. Our emissions have a steady, cumulative effect. The variation in CO₂ due to the events of the last month or so is too small to even show up on the Mauna Loa record, let alone in the noisy temperature record.

CO2 increase in the atmosphere near perfectly tracks human emissions at around half the emissions:

Even if that is pure coincidence: human emissions increased slightly quadratic over the years and so did the increase in the atmosphere and thus the net sinks (which are in direct ratio to the extra CO2 pressure in the atmosphere).
The point is that the sinks over the past 60 years were near always smaller than what humans emitted, thus nature was a net sink for CO2, not a source, but not fast enough to remove all human extra CO2 (as mass, not the original molecules!) in the same year as released…
If humans would halve their emissions, there was no increase of CO2 in the atmosphere anymore…

Some way down the track the productive sectors of society must pay the piper – all through a mass failure by governments to implement contingency plans in case of a pandemic. They had plenty of warning. They are to blame, let there be no doubt. Now they buy redemption by using their subjects’ reserves and mortgaging their future

Why did just one country swim against the tide? The Swedish are possibly the highest taxed on Earth. Did their government realize that there was simply too little fat in the system to withstand higher taxes in the future?

The future is a socialist’s dream: high taxes and state intervention, nationalised services such as airlines, rail; perhaps even fuel supplies. Add a throng of families with inadequate incomes: left-leaning voters.

The unemployed, the unemployed. Just look at the numbers and be honest. In the US the highest since the Great Depression. Some are saying 20 %

Don’t blame the virus. The real catastrophe is man-made and irreversible, the damage done. We are saving some lives and the reputation of health services (note services). Is it really worth it?

The nursing homes give evidence that a very poor job was done protecting the vulnerable.

Rather than isolation, nursing homes were practicing herd immunity by grouping health and infected patients and staff.

Was each patient given an isolated air supply? Or were they sharing air with infected patients and/or staff?

Why was this not put into effect years ago to protect against flu and other communicable diseases?

Independent air supply for each patient in a nursing home would even allow family and friends to visit.

There’s a common misconception that “assisted living” facilities are nursing homes. The latter are health care facilities, the former are not but are counted as nursing home deaths.

“There have been 66,000 reported deaths at the time of writing, but the Centers for Disease Control concluded a couple of days ago that, based on excess mortality data, deaths have been under-reported by about 15%. So there have really been about 76,000 deaths.”

Yes but at the same time even more people are counted that happened to die with CV19 present, that would have died anyway (institution acquired after end of life admission), and doctors have been doing death certificates with CV19 by symptoms (and politics) without actual testing – causing over counting too.

I pointed out before the way that in the 2015 flu in the UK old people that died of something else were merely noted as having the flu too (inconsequentially), but this year with CV19 the emphasis has been reversed.

It will be impossible to get to the true figures even when this is all over.

One thing for sure, the more testing that is being done globally, the faster the death rate is shrinking.

May 3, 2020 2:20 am

Maybe. For IPCC says CO2 persists in the air for about 125 years …

As pointed out above, the anthropogenic contribution to the CO2 budget is so tiny that, even if it is changed a lot, the effect disappears into the noise.

The other thing is that the CO2 books don’t balance. link The IPCC acknowledges that.

The only way CAGW works is for CO2 to have a very long residence time. Proving that requires that the CO2 budget is known with great precision, which it isn’t.

That article at WUWT was firmly commented, as I see tens of comments by myself…
Of course there is a balance: yearly human emissions are known by taxes and the increase in the atmosphere is measured, thus the difference between these two is what nature net has emitted or absorbed at the end of a full year, whatever the individual natural fluxes and their direction.

The e-fold decay rate of our emissions in the atmosphere is around 50 years. Indeed much shorter than what the IPCC uses via the Bern model and there is no saturation in sight…

A few musings about excess deaths.

I don’t know about other countries, but here in Spain they cancelled all medical services except emergencies. From my toddler’s vaccines to my elderly neighbour’s chemo, all cancelled.
What’s considered an emergency? A burst appendix. The doctor won’t see you with, for example, an inflamed tendon. You are sent home to self-treat with paracetamol. How many extra deaths are due to six weeks of treatments cancelled, patients sent home, overuse or misuse of over-the-counter medication? Normal diseases haven’t gone away. Are there any numbers available? How many people are still treated for diseases that aren’t Covid-19?

Then there’s depression. How many old people live alone and haven’t seen anyone in weeks? And in retirement homes, how many are forced to eat alone now and spend their days in what amounts to solitary confinement? The caretakers spend as little time as possible with their charges, wearing gloves and masks and what not. Is this causing depression? Anecdotal evidence tells me that yes, it is. Does anybody have numbers?
In normal times, caretakers in retirement homes don’t wear masks. They use gloves only when treating wounds or changing diapers. It’s been long known that beyond a certain point, more hygiene measures get counterproductive: They lower the risk of infection, but depress the people.

My daughter (adrenal insufficiency and 6 mos preganant with monozygotic twins, blood pressure issues and gestational diabetes) had a sore throat a month ago, so her OB appointment was cancelled, she was sent for a COVID test and put under house arrest for 4 days, not even allowed to walk the dog. Negative test, but sore throat continued. Triage nurse again sent her for another test rather than her OB appointment; would not even look in her throat for fear of catching SOMETHING. She has a long history of repeated tonsilitis, so having a stock of amoxicillin, she dosed herself and is feeling much better. This is what has happened to care in the high risk OB clinic in Montreal.

Aclima Measures 10% Drop in Carbon Dioxide Across the Bay Area

As the COVID-19 response altered behaviors that generate emissions, toxic pollutants declined, especially those caused by driving in heavy traffic. At the same time, greenhouse gas emissions dropped. The Aclima mobile sensor network is actively measuring hyperlocal air pollutants and greenhouse gases in every county in the Bay Area, across a range of parameters including CO₂. By averaging our block-by-block measurements at the county level from February 6 to March 19, we can see the trend of CO₂ declining in a pattern similar to NO₂ starting in early March resulting in a 47 ppm or 10% decrease in CO₂ levels.

May 3, 2020 5:48 am

Water vapour has a residency time of about 9-10 days in the atmosphere, as compared to 20-50-125 years for CO2. Take your pick, I don’t know if anyone really knows the real residency time of CO2. But at former levels of increased fossil consumption, there would be more water vapour which would flow continuously through the atmosphere if it didn’t change much. Now that it has dropped a certain percentage, will it show up in any future temperature or rainfall record? I don’t know, and how would you ever know as compared to any simultaneous change in natural variation? It could be half, equal or double and no way to make sense of what was happening unless it was a permanent feature, this temporary reduction in fossil burning and water vapour creation. Maybe after 3-4 years there might be some gleanable data.

I would say anthro water vapour might be a feature locally in high urban population situation, perhaps adding to the rain intensity of a local thunderstorm for example, which would skew the record since the rain from that additional water vapour would be local and minimal. But it might cause a small local flood that jacks up insurance rates and then they blame climate change en masse. Even though it was all local and then extrapolated to be global. Hence the false global alarmism, IMHO.

Reply to  Earthling2
May 3, 2020 7:57 am

The “residency time” for CO2 used in the models is not a physical parameter. It is a “fudge factor” used to make the correlation between burning of fossil fuel and the rise in atmospheric CO2 concentration. Analysis of the naturally caused variation of CO2 in the Arctic proves that practically all CO2 emissions (both natural and fossil fuel burning) are removed from the atmosphere each year. The year to year increase is because natural emission concentrations have been increasing since the 1950s. I expect these natural increases to continue for several more years. A drastic decrease in fossil fuel burning will not show up in the rate of increase in the atmospheric concentration of CO2. Natural emissions are at least 20 times greater than man made emissions. A 25% reduction in man made emissions would be expected to reduce the rate of increase by only 1%. The natural year to year variation in the rate of increase is greater than that.

Ignored by the IPCC and several leading skeptics, as the residence time is irrelevant for the increase or decrease of CO2 in the atmosphere.

It is like the difference between the throughput (turnover) of materials through a factory and the gain (or loss) a factory makes at the end of the fiscal year…

Reply to  Fred Haynie

The residence time is roughly known on the base of the solubility of CO2 in the sea surface with seasonal temperature changes and the O2 and δ13C changes for vegetation over de seasons.
About 5 years, or 4 years if you include the diurnal CO2 exchanges in vegetation.

The human emissions and increase in the atmosphere are known and the difference makes that the “practically all emissions” are more sink than source over the past 60 years, so natural emissions may have increased or decreased or staid even, that doesn’t matter at all, as humans are the cause of the increase, not nature.
A human emissions decrease of 25% will show up if that is sustained over at least a full year, which is not what I hope for…

Reply to  Ferdinand Engelbeen
May 5, 2020 2:05 pm

So you are saying that the sinks take up all the natural emissions but only about half the man made emissions. I don’t believe that. Natural emissions have been increasing for over 60 years along with the increases in man made emissions. The fact is that natural emissions are about 20 times natural emissions. The cold waters in the polar regions are always sinks. The sink rates are being controlled by the rate of delivery of CO2 to the sinks, not thermodynamics.

Reply to  Ferdinand Engelbeen
May 6, 2020 1:54 pm


The natural sinks did take up all natural emissions, because the natural fluxes are mainly seasonal and temperature driven. The seasonal cycle hardly changed over the decades:

There is no reason to assume that the winter-summer temperature difference changed a lot over the past 60 years, thus neither the natural in/out fluxes between atmosphere and oceans or vegetation.

There is also no reason for nature to take any extra CO2 out of the atmosphere, whatever the cause, except that the increased CO2 pressure (pCO2) in the atmosphere pushes more CO2 in the oceans and vegetation. That is a different process, which is pressure driven, thus completely independent of the temperature driven huge seasonal CO2 fluxes.
The extra CO2 pressure in the atmosphere makes that there is a slight difference between CO2 inputs and CO2 outputs, which is directly proportional to the extra CO2 pressure in the atmosphere above the ocean surface average temperature, which for the current ocean surface temperature is about 290 ppmv.
How much is net absorbed by oceans and vegetation is independent of the huge in/out fluxes or the momentary human emissions of one year, but only depends of the extra CO2 pressure in the atmosphere.

Yearly human emissions increased a fourfold in the past 60 years. Natural emissions should have increased a fourfold too to be the main cause of the increase in the atmosphere (that implies a fourfold decrease in residence time!), if the natural fluxes were pressure driven, but they are not…

No idea if that man is right:
Scrutinizing the carbon cycle and CO2 residence time in the atmosphere
presuming only: The anthropogenic contribution to the actual CO2 concentration is found to be 4.3%, its fraction to the CO2 increase over the Industrial Era is 15% and the average residence time 4 years.

Complete abstract:

Climate scientists presume that the carbon cycle has come out of balance due to the increasing anthropogenic emissions from fossil fuel combustion and land use change. This is made responsible for the rapidly increasing atmospheric CO2 concentrations over recent years, and it is estimated that the removal of the additional emissions from the atmosphere will take a few hundred thousand years. Since this goes along with an increasing greenhouse effect and a further global warming, a better understanding of the carbon cycle is of great importance for all future climate change predictions. We have critically scrutinized this cycle and present an alternative concept, for which the uptake of CO2 by natural sinks scales proportional with the CO2 concentration. In addition, we consider temperature dependent natural emission and absorption rates, by which the paleoclimatic CO2 variations and the actual CO2 growth rate can well be explained. The anthropogenic contribution to the actual CO2 concentration is found to be 4.3%, its fraction to the CO2 increase over the Industrial Era is 15% and the average residence time 4 years.

Sorry but Dr. Berry is completely wrong.

1. He uses the residence time as base, but residence time which is about turnover of CO2 in the atmosphere and the time needed to remove some extra CO2 above equilibrium out of the atmosphere have nothing in common.

2. He uses the reverse of the residence time:
residence time = mass / output
He reverses that to:
output = mass / residence time.

You may do that if and only if all input and output fluxes are unidirectional, which is not the case at all: in spring/summer ocean CO2 is released and is absorbed by growing vegetation with the atmosphere as passing by station. In fall/winter the flux is reverse. The net effect in the atmosphere after a full year is a few ppmv increase for about 50 ppmv CO2 passing by in both directions, thus a throughput of 100 ppmv on 400+ ppmv mass. The residence time still is the same, as that is indifferent for the direction of the fluxes, but there is zero effect on the in/out fluxes, as these are not controlled by the CO2 mass in the atmosphere but by the temperature effect on vegetation and ocean surface…

The herd immunity concept is not “letting people die”. That is an offensive misrepresentation. Unless the virus just disappears for no apparent reason – wishful thinking – it can only be defeated by the population acquiring herd immunity. There are 2 ways of achieving this. We can lockdown until a vaccine is discovered, trialled, licenced, manufactured in large quantities and administered. If this is going to take 12 – 18 months, can we really lockdown for that long without consequences that are worse than those of the pandemic itself ? Or we can allow infections amongst the young and healthy who would suffer no symptoms or only mild symptoms.

In my opinion, neither full lockdown nor “let it rip” was the correct option. We should have instigated a regime of very strict isolation and protection of the elderly and those with underlying health conditions. The young and healthy should have been allowed to continue normal life. Exposure of the young and healthy to the virus would have created the herd immunity necessary to eradicate the disease. Vulnerable groups cannot be totally protected, as we have seen from the full lockdowns around the world. A more targeted lockdown more rigorously enacted might have been better.

If medication totally reduces the risk for everyone, which can be found with extra time given by lockdown then ergo you do not need lockdown.

Carbon Model Calculations by Peter Dietze

IPCC’s emissions scenario IS92a is used as first input to a simple carbon model, parametrized in four different ways. A second simulation is performed with IS92aD, a reality-adapted IS92a scenario which peaks at 12 GtC/yr around 2040 and then reduces emissions until all the usable 1,300 GtC are burnt in 2150. The CO2 concentration perfectly matches present observations and does not increase to more than 470 ppm. The airborne fraction reduces to near zero in 2070. The third simulation uses the SRES A1 scenario from IPCC TAR. Eyestriking exaggerations of IPCC’s Bern model results (677 vs. 540 ppm) and an unrealistic CO2 lifetime of 570 years are revealed – being confirmed as well by a WRE550 stabilization scenario run showing a seven times too high CO2 increment. Essential discussions are presented.

Mr. Monckton is right about global warming and the corona virus. The economic shutdowns add to Mr. Monckton’s credibility. The virus models showed that anywhere from 1 million to 2.2 million Americans would die if nothing was done to mitigate the Wuhan virus, and that between 100,000 to 140,000 Americans would die if mitigation measures were taken.

The current death toll in the U.S. is 68,000 and climbing which means the virus computer models are certainly in the ballpark in their initial projections so claiming an economic shutdown is not called for is denying reality. Unless, of course, it is acceptable to the one making the clam that we allow 2 million people to die that we could have saved had we taken action.

What is not credible are all the virus computer model bashers who have gotten it all wrong and want us to make policy based on their delusions and misunderstandings of the virus computer models.

When can we expect those who have tried to destroy the credibility of the virus computer models and the authorities who use them, going to apologize for misleading the public and causing public consternation and confusion?

“The Planck or zero-feedback sensitivity parameter P is 0.3 K W–1 m2 (ibid.).”

No it is not. This is equivalent to 1.62 W/m^2 of surface emissions per W/m^2 of forcing and is not the zero-feedback sensitivity, but the steady state average sensitivity after all ‘feedback’ like effects have already had their effect. This is not and can not be further amplified by additional feedback. The feedback of 0.62 W/m^2 per W/m^2 of forcing is already accounted for.

To be consistent with feedback analysis, the zero feedback sensitivity would be 1 W/m^2 of surface emissions per W/m^2 of forcing corresponding to less than 0.2C per W/m^2, i.e. an ideal BB at the surface temperature. They claim that 1.62 W/m^2 per W/m^2 of forcing is the ‘zero-feedback’ sensitivity, but don’t explain where the extra 0.62 W/m^2 of surface emissions per W/m^2 of forcing is coming from. They get away with this by incorrectly claiming a temperature output rather than an emissions output from the climate feedback model. Again, to be consistent with the feedback analysis, the extra 0.62 W/m^2 per W/m^2 is the feedback and is the entire extent of the feedback PERIOD.

How is sweden doing? Are they up to 16,000 deaths a day as the exponential growth models predicted for an open for business nation?
Maybe they are recording 8,000 deaths per day?
Well, they have to be recording at least 1,000 a day by now?
250 a day has to be the least they should be suffering for still allowing people to work and earn a living!
100 per day then?
Close to it… They reached 108 deaths per day on a 7 day rolling average and have since then been declining down to under 70 deaths per day on a 7 day rolling average.
Impossible, the models were saying they would see 18,000 deaths by september, and that would require them to be dying in far larger numbers and still climbing!
Those models had an agenda, just like Lord Monckton has one. I do not know what his agenda is, but the agenda of the models was to destroy western civilization for the benefit of the Chinese by forcing governments who are supposed to be responsible adults in the room to shut down their economies.
The models began by arguing that we needed to save the health care system from being overrun by sars-cov-2 victims. We needed to flatten the curve. It sounded good. But in actuality, the healthcare system, at least in most 1st world nations could have handled the virus outbreak, with some stress obviously.
Since our healthcare systems did well, the modelers have changed the goal to slowing the number of deaths so that the deaths between now (whatever day it is) and some period a few months off, are fewer. Of course, this is a virus, no matter what day today is, if you can argue that opening up for business will cause more deaths in the same amount of time, then this argument is always true. But at the end of the day, being a virus that is stealthy and highly contagious, it will eventually reach just about everyone regardless of whether you slow it down or not.
Sweden is one of the only control groups we have to see if this argument is true. So far, after 6 full weeks of open for business, more or less individually determined social distancing, all schools except higher education still open, they have not seen the death rates that modelers argue we would see if we went the way of Sweden. 6 weeks is certainly more time than is needed to see if the exponential growth model is accurate or not. We do not need to wait years to see if what Sweden is doing is right or not. We have many more weeks than was needed to see if it was going wrong. If it were going wrong exponential growth shows up exponentially fast!
In the United States of America, we have probably burned well over $10,000,000,000,000 in our worthless efforts to save lives. That is 10 trillion dollars that will not be available for many other things. That is 15 years of our military budget. Gone, vaporized, destroyed, missalocated.

Those models had an agenda, just like Lord Monckton has one.

I too happen to disagree with Monckton over a few issues, but I have newer felt he even remotely served an agenda he would not be open about.

Astonerii, I agree with most of what you are saying. I also agree it is hard for many people to comprehend and live “stay home” orders. Both Monckton and I are not hit that hard, we both have pretty good housing in rural surroundings, but as more than half the worlds population now live in cities, the curfew must be terrible in the long run. And, as you say, Sweden has pretty much proven to have been the most mature and data driven.

We Swedes will send the you the bill for limiting our production of exported goods. 🙂

They only have 10 million living there, why don’t you compare them to Czechia who also have only 10 million?
Sweden 22nd in the world with 22,317 cases and 2679 deaths growth rate 5.8.
Czechia 42nd in the world with 7,764 cases and 245 deaths growth rate 2.8.
Or Singapore, or South Korea, or Taiwan?

As everyone loves to argue, everything that is not the same is different. Thus you cannot get anything from comparing different things.
But, Sweden is in for a world of hurt in the next few weeks. Or maybe it will take longer. Ok, not yet, maybe a little longer. But since I support lockdowns, and since Sweden did not lockdown, then I know for a fact they are wrong and will suffer for it. But, then again, maybe since Sweden is not doing so badly, maybe they are really locked down, but just never told anyone they are, because, science bro!
You see, I keep seeing these arguments against Sweden. They are not as densely populated. Different population totals. They are further north. They may not have government lock down, but in spirit they are locked down. The list goes on an on and on and on and on.
But the bottom line is that you can compare different things to one another.
Sweden is not as densely populated as a whole country as many others. Their biggest city is not as densely populated as New York City is. But they do have cities, and they have wide open areas, and 80% of their population in lives in city of one form or another. So, for the most part, they are similar enough to the entirety of the worlds countries to make some comparisons. On a per capita basis, say per millions, they have several nations that are much worse off than they are. Spain, Italy, United Kingdom for instance are far worse off than they are. They also seem to be fitting into a band with several other nations. The United States of America for instance, and there are other nations way down and doing great. Germany, Japan.
And the difference is this. Sweden is open for business, and it is in the middle of the pack in general. It is the control group for whether economic suicide is a valid response to the virus. And the evidence shows that economic suicide is not a valid or valuable response to the virus. Better to keep working, creating the wealth that allows you to deal with problems and remain healthy and alive, rather than hunker down and suffer the same with far less resources.
Would you rather face a freezing winter with plenty of oil and gas to keep warm, or would you rather stop working, stand outside screaming, “stay away cold” and face winter with empty fuel tanks?

Yes we can see that it died down in April & May, it only went from 863184 at the end of March to 3,481,371 now.
This is not the flu.

All those who think it is a flu, should volunteer to work in hospitals without PPE-s, get infected, recover speedily and build immunity. While armed with a new health status start rebuilding post-corona economy and take advantage of enormous opportunities for those who get there first.

As you were with the catatonics and seizures doomsters as we’ll all adapt-
In the meantime don’t forget to take your medication if the CO2 levels are a bit low with the Rona shutdown and early adapters should keep some dry ice on hand as smelling salts. Soda pop is handy in an emergency too.

The USS Roosevelt has 1,100 cases of Wuhan Virus. Four people went to the hospital. One died. This group is younger than the average population, but the Navy isn’t populated with teenagers – many sailors officers stay in the service for more than 20 years, some for more than 30 years. And, we’re not talking about a bunch of marines! People in the navy are only marginally healthier than civilians of the same age range. (I was honorably discharged after six years of service during the Reagan Admin, so I know more than a little bit about this.)
It’s high time we talk the germaphobes down and end this hostage crisis! Besides, the curve has been completely flattened. That was supposed to be the point, right? In the US at least, you can count on one hand the number of places where the health system could possibly be overwhelmed if infections ramped back up.
The US has a rich history of civil disobedience, starting from before there was a US. It’s looking more and more like it’s time to add a new chapter to that history.

You are close. You have found a covid statistical anomaly. A cohort of individuals who have an unusually low death rate for covid.


Vitamin D Insufficiency is Prevalent in Severe COVID-19

The sailors, sail in warm waters and hence are not Vitamin D deficient.

One death out of 1000 covid cases.

Prevalence and correlates of vitamin D deficiency in US adults

42% of the US population has been shown to be Vitamin D deficient. With elderly and dark skin people the most Vitamin D deficient.

82% of the US dark skin (‘black’) citizens are Vitamin D deficient.

Dark skin people in the US and in London had roughly three times as many deaths per covid 1000 cases as white skin people.

Chart summarizing the results of Vitamin D studies. Roughly 70% reduction cancer, almost elimination of type 1 diabetes, 64% reduction in multiple sclerosis, and so on. There is also a strong correlation with dementia and Vitamin D deficiency.

William: The recommended vitamin D supplement that has been confirmed by extensive testingt o be absolutely safe and close to sufficient to reach body optimum is 4000 UI/day.

This is a link to the US researcher who was responsible for the oversight of all Vitamin D research from 1000 UI to 10,000 UI in the US. There were zero health problems observed due to the supplements, in that range.

This video is a lecture from the US researcher who has forced to treat Vitamin D supplements the same as dangerous cancer drugs. He was responsible for oversight of all US Vitamin D supplement research from 1000 UI to 10,000 UI and beyond.

There were zero problems in any of the research for Vitamin D supplement use from 1000 UI to 10,000 UI.

P.S. This is all new news to me. There is sufficient evidence that there is a case for criminal negligence.

In the Canadian system I have unused power. This will not stand. There will be a political explosion in Canada when the population finds out how long the Vitamin D research has been ignored and held back because of special interests.

This is system rot, not failure.

Thanks for that Vitamin D summary, William. Very useful. I take Vitamin D supplements so I’m glad to learn it is doing me so much good. 🙂

I haven’t had the flu in so long I can’t remember the last time, and I take flu shots only sporadically. Maybe that luck will hold for the Wuhan virus. If not, I’m off to the Doc for some hydroxychloroquine ASAP.

A headline this morning states several hundred workers at a meat packing plant in Nebraska have tested positive for the Wuhan Virus. ALL of them were asymptomatic.
Of course, we all know how much sunlight meat packing plant workers get, in general, and this one is located in that famously sunny state of Nebraska. So, nothing really to see here folks…

“CO2 persists in the air for about 125 years”

I’m not sure if anyone addressed this in the comment section. My understanding is that residency time is, at most a couple of decades, maybe a little more, or a little less. It’s been a while since I’ve studied this particular subject. I’ll do some more research, but if anyone has seen any recent studies on residency time, a like would be awesome. Thanks!

From the article: “But there are now 1.131 million cases in the United States. Allowing for the current gentle slowing in both reported cases and deaths, even if there were no more cases (and at present there are 30,000 new ones a day), by mid-June and perhaps sooner there will have been 125,000 U.S. deaths associated with the Chinese virus – and counting.”

It’s time to call out those who have been trashing the virus computer models, claiming they are inaccurate, and were not a reason to put society on lockdown. The trashers are obviously wrong, and they should admit it and also admit that the authorities were correct to institute social distancing in order to save millions of innocent lives.

The virus computer model bashers have caused doubt in the minds of the public about how and why this pandemic is being handled. Putting doubt in the public’s mind is not a good idea in a crisis, especially when that doubt is fueled by arguments that turn out to be wrong.

The pulbic is misled by the Leftwing media and now those who don’t want the economy shut down are chiming in claiming we didn’t have to do this in the first place because the computer models are all wrong. But it is those who make these claims who are all wrong.

And our current death toll has been kept down by our social distancing efforts, and although I can’t prove it, I would say that hydroxychloroquine has had a role in keeping the death count down.

It’s time for the virus computer model bashers to admit they had it all wrong and they treated Dr. Fauci and Dr. Birx unfairly, accusing them of all sorts of perfidity, and undermining the Plan to fight the Wuhan virus in the process.

It’s gotten to the point that even a mention of the virus computer models gets a firm kneejerk dismissal from some quarters, even though there is nothing wrong with the models. Good work, you propagandists. Your propaganda is having an effect, but not the one you want. It’s just causing more problems because of the misunderstandings you have introduced to the subject. You need to correct yourselves and stop panicing people with disinformation about the virus computer models.

My brother, a true believer in the Wuhan Virus models, sent me a link from the seditious rag, The Washington Pravda, that dismissed the models used every year to calculate flu deaths. Deaths are actually much, much lower doncha know! So, the Leftists disparage models when they feel like it. Of course, that article is the equivalent of relentlessly revising historical temperatures down in order to make current temperatures look like they are problem when they are not.
If you feel badly about our “kneejerk reaction” to doubt models, you ought to take it up with the charlatans that squandered the public trust in the last couple decades to promote a faux crisis.
Also, it’s been quite awhile since I read it, so perhaps you could remind me, who is the subject of the cautionary tale of the boy who cried wolf too much? Is it the boy or his audience?

“If you feel badly about our “kneejerk reaction” to doubt models, you ought to take it up with the charlatans that squandered the public trust in the last couple decades to promote a faux crisis.”

No, I dont feel badly about it, I think it is Wrong. You’ll see in the not-too-distant future.

Making excuses for critiizing the virus computer models based on the human-caused climate change computer models just shows confusion on your part. Noone bashes the climate computer models more than I do. I do so based on the fact that climate change models are not based on facts but on guesses. The virus computer models are different. They are based on facts and educated guesses and they are compared to reality, whereas, if the climate models were compared to reality, they would fail every time.

The virus computer modelers say the mitigated deaths from the Wuhan virus will be between 100,000 and 140,000. You apparently say that is not correct. I’m happy to watch this all unfold, and I’m pretty sure you are the one who is going to be wrong. I’m sure you will correct me, if that time ever comes. I don’t expect to be hearing from you on this matter.

That Wuhan Wolf has killed about 70,000 Americans. The Boy who cried wolf was referring to an imaginary danger.

Quoting myself: “It’s gotten to the point that even a mention of the virus computer models gets a firm kneejerk dismissal from some quarters, even though there is nothing wrong with the models.”

Just to emphasixe the point, I just heard Brian Kilmeade, an otherwise smart guy, say on Fox & Friends this morning that the virus computer models are all junk.

The Virus Computer Model Disinformation Specialists are doing an effective job. Thanks for sowing confusion in the ranks. A wonderful contribution to humanity.
