CERES and the Greenhouse Effect.

In 2017 we became interested in the CERES data, in particular the measured trend of increasing longwave radiation to space. Nobody seemed to register the significance of this, so in 2018 we downloaded the data and produced t his graphic: It showed very clearly that contrary to the greenhouse effect narrative that current warming is caused by increased absorption of long wave (LW) radiation to space by human CO2, that this radiation to space was actually increasing. It further showed that net radiation to space, a value calculated by subtracting the sum of SW and LW outgoing  from incoming solar radiation (hence the inverted axis), was controlled by a marked decrease in solar SW radiation being reflected back to space. In other words, it showed that our planet was warmed not by human CO2, but by a decrease in solar SW radiation reflected to space and therefore absorbed by the surface and atmosphere. We presented this argument continuously in social media and blogs, including to such luminaries as Gavin Schmidt, now director of NASA GISS. They could never refute the data, but chose to ignore it, especially since the Trunkmonkey Research Institute has little standing in those circles. In 2020, before the CERES data format was changed, we updated the graphic to show that the trends had continued.

Comes now a fully peer reviewed paper supporting our argument.


They comment:

“the root cause for the positive TOA net flux and, hence, for a further accumulation of 
energy during the last two decades was a declining outgoing shortwave flux and not a 
retained LW flux.” 

The authors have taken advantage surface fluxes, new to the CERES data, to directly measure the greenhouse effect. They do this by subtracting top of atmosphere upward LW flux from the surface upward LW flux in clear sky conditions. They find an attenuation of about 130W/m2 (33%) under clear skies from all the atmosphere except the liquid water and ice from clouds. 

Under cloudy skies, however, they find their correlations with CO2 and water vapor break down entirely, and now complicated by the absorption liquid water and ice in the clouds, a much reduced attenuation of 33W/m2 (12.6%). They comment:

” the rise of the greenhouse gas concentration from 2001 to 2020 had a measurable
 effect on the LW flux in the “Clear Sky”, covering about 1/3rd of the Earth surface. In 
the cloudy part, about 2/3rd, this effect was much smaller, if significant at all.”

Not only is the root cause of recent warming not human CO2, but rather increased shortwave absorption; but the greenhouse effect as the dominant narrative would have it significantly applies to only 1/3 of the earth’s surface.

Steve Rayner in Policy Making in a Post-Truth World

The problem is not that charlatans have duped the public with pseudoscience and misinformation but rather that the expert class and the institutions in which they are embedded has failed to attend to the panoply of public values that are unavoidably implicated in the construction of policy-relevant science. The solution, they argue, is not more research, better science communication, or louder condemnations of science denial. Instead, it is greater cognitive pluralism — both in how we define problems and how we shape solutions — so that both are better able to speak to a broader range of normative postures toward risk.

Corona with Lyme

A seasonal second wave of SARS-2 infections has spread around the Northern Hemisphere since the last post. Generally deaths are far fewer, both because many of the most vulnerable have been exposed and because a younger and healthier group is getting it now.
We digitized the available graphs of deaths for the 1918-19 pandemic. these were available for several US cities and for England.

The three Eastern Seaboard Cities of Boston, D.C., and Baltimore are pretty similar with DC having more of a preamble in July and Baltimore getting off easier on the second wave. San Francisco was more like the Eastern Seaboard but shifted. It had an easier first wave and a rougher second. Augusta had two more equal waves, with the second worse than the first. England got off easy in both waves and its first wave was opposite phase. There were substantial regional variations in phase and severity.

There are considerable phase and severity variations in the current pandemic around the US as well. What is really striking is how we have dragged the current pandemic out so much longer than prior ones.

Data for 1918 uses SF as a proxy, and requires a 50x separate scale. December data  for Covid is incomplete and will increase a bit. If we did actually flatten the Covid death curve with our interventions, the unflattened curve would have been impressively steep. I suspect we just delayed the waves.

A joke last winter was that if Covid lasted until summer, we could have corona with Lyme (disease). It did.

Fuel Moisture and the Dragon’s Breath

Fuel moisture content equilibrates with atmospheric humidity on a scale of hours to weeks depending whether it is dead or alive and how thick it is. There is widespread superstition that drier fuels from climate change can be blamed for the rash of fires recently. Here we explore the relationship between atmospheric temperature and humidity to show that temperatures have not increased enough to reduce fuel moisture more than 3%.

The United States Forest Service has been studying fires for a long time. A graphic from USFS research paper INT-359 below shows the relationship between atmospheric temperature and humidity in an Idaho forest.

It can be seen that the temperature changes about 25 degrees F and humidity changes about 25%. Santa Rosa, CA has a similar diurnal range. We can generalize that the relationship is symmetrical and inversely related at 1:1 degrees F to %humidity.

Santa Rosa and nearby Windsor have lost houses each of the last three years. How much has Santa Rosa’s climate changed? Below is a graphic from Jim Steele showing average high temperatures for Santa Rosa.

It can be seen that average maximum temperatures in Santa Rosa have declined since the 1930’s like most of California and the American West. Maximum temperatures control fuel moisture low points. Atmospheric humidity and fuel moisture must have increased from the 30’s, although they have been decreasing since 1980.

The average temperature of the entire state of California is a fatuous metric for fires, but even if we could come to believe the average somehow controls the many areas like Santa Rosa where temperature has decreased, the increase of 2.5 degrees F from 1930 would only yield a 2.5% decrease in fuel moisture. The dragon’s breath needs more than that.

Furthermore, NASA has come out with a global fire area assessment.

Seems the dragon just likes California.

Will a Vaccine Work?

Last year’s seasonal flu vaccine was judged 45% effective. This is typical effectiveness for a seasonal flu vaccine after half a century of practice. Now let’s say 50% of the people will take the vaccine in line with recent studies. This is multiplicative so the population effectiveness is 22.5%. SARS 2 has an Ro of at least 3, so a vaccine would need to be effective for 70% of the population. 22.5% will help but will not end the pandemic. However, natural immunity from recovery has been building. Unlike vaccine immunity based only on who was given or will take the vaccine, natural immunity is based on the virus finding the most susceptible first. Natural group immunity may require only ~20% of the population to end the pandemic. The extent of natural immunity is currently unknown. The pandemic will end when either the natural or vaccine threshold of group immunity is achieved, or some combination thereof. What is clear is that a significant contribution from natural immunity will be necessary for a vaccine to work.

Seasonal Darwinism

The time scale of viral evolution is hours. The infectious vectors called virions can each produce thousands of copies of themselves from a single infected cell. Within hours, natural selection will determine which virions will successfully infect another cell/organ/individual; and which will die.

In ecology, the opposing reproductive strategies of wide dispersal and rapid colonization vs. taking a stand and extracting maximal resources are mathematically modeled as r and k selection, respectively. R selection favors being a weed. K selection favors being a giant sequoia.

The hypothesis of seasonal Darwinism attempts to explain the mysterious seasonality of some viruses as near real time r selection, favoring dispersal and transmissivity, during the summer when human populations are better fed, more dispersed, more outside, and more vitamin D enriched; and k selection, favoring virulence, in the winter when these factors are reversed.

SARS 2 is a single stranded positive RNA virus. It must first create a negative copy for replication, making replication and translation at the same time more difficult. The virus must balance these two processes, and the balance struck determines how many copies of itself it makes–its virulence. Selection based on this balancing strategy, with virulence favored when it is easy to find new hosts, and transmission–producing fewer copies for a longer period of time–when finding new hosts becomes more difficult. 

One might argue that SARS 2 is not seasonal since a resurgence has taken place over much of the northern hemisphere summer, but this resurgence has clearly been less virulent, with a far lower case fatality ratio. The coming winter will tell.

Credit: These ideas are strongly influenced by Patrick Stewart on his blog, oldwivesandvirologists. He believes strongly in a temperature switch in the viral RNA secondary structure. Whether or not this proves to be the case, natural selection based on conditions of the host population–seasonal Darwinism–can explain much of viral seasonality.

Fun With Cut and Paste

Perusing the state new case curves on https://rt.live/ some patterns become apparent.

Some states with early exposure are on a clear downward trend.

Some southern states with later exposure are on an upward trend, California being an exception by early exposure.

Some  early starting midwestern states seem over the hump, DC being eastern with similar shape.

Some later starting states also seem over the hump.

Some northerly late starting states are climbing.

Some states are cruising.

Some show a second wave, and Wyoming which never lifted off.

  1. There is no consistent relationship between lifting house arrest and new cases.
  2.  There is no indication that seasonality is slowing the spread.
  3.  Below Rt=1 (faintly visible in background) Rt can rise and new cases can still fall. The inverse is also true.
  4.  Washington State has managed a modest decline with Rt>1.
  5.  Utah has had steady Rt>1 for the entire period. A month elapesd before there was appreciable increase in cases, and it experienced a striking rise without any increase in Rt.

The more you know, the more you know you don’t know Jack.

Trouble with Model

We had been trying to do this ourselves but found this fun model: https://gabgoh.github.io/COVID/index.html


We can attest that the model parameters agree with our own incomplete efforts. It has lots of fun stuff to play with, and you can test the sensitivities of all the variables. We disagree with the commonly assumed R(initial) value ~2.5. The table of calculated values on the site has an average of 4.5. An excellent paper in review, Sanche et al at Los Alamos available on the CDC website finds Ri over 5. This model goes completely off the rails at these values so we set close to 3. We also disagree with a short infectious duration. Symptomatic spread alone is at least 5 days and there are at least 3 days of asymptomatic. Surprisingly, the model is insensitive to infectious duration, merely shifting the timing. Above we set the model to as close as possible to N=1 million so for the US you multiply by 327. The model seems excessively sensitive to initial infections. By limiting to 1 million and 1 initial behavior improved. Hospitalizations are a reasonable match, but deaths are too low. What we like about this is that contrary to the IHME model which predicts a decline that has not materialized, this shows we are going to be dealing with this for a while.

Above we tried to coax the model to replicate data we have for deaths and hospitalizations. We know from the Covid Tracking Project and Worldometers that daily hospitalization accelerated to 79,000 about April 15 and have declined only slightly since  ever since, defying the IHME model’s projected decline. Daily deaths reached a high of 2800 about April 20, and have likewise failed to decline according to IHME.

We were able to get a reasonably sensible approximation of actual US hospitalization and death only by removing intervention altogether. This makes no sense as intervention must surely be a factor. The model also takes way too long to reach appropriate values. We are seemingly only two months in.

We have developed some sympathy for the difficulty of modeling, but are forced to conclude that important variables are not yet included.

The Possible Origins of 2019-nCoV Coronavirus

The 2019-nCoV coronavirus has caused an epidemic of 28,060 laboratory-confirmed
infections in human including 564 deaths in China by February 6, 2020. Two descriptions
of the virus published on Nature this week indicated that the genome sequences from
patients were 96% or 89% identical to the Bat CoV ZC45 coronavirus originally found in
Rhinolophus affinis (1,2). It was critical to study where the pathogen came from and how it
passed onto human.

An article published on The Lancet reported that 41 people in Wuhan were found to
have the acute respiratory syndrome and 27 of them had contact with Huanan Seafood
Market 3. The 2019-nCoV was found in 33 out of 585 samples collected in the market after
the outbreak. The market was suspicious to be the origin of the epidemic, and was shut
down according to the rule of quarantine the source during an epidemic.
The bats carrying CoV ZC45 were originally found in Yunnan or Zhejiang province,
both of which were more than 900 kilometers away from the seafood market. Bats were
normally found to live in caves and trees. But the seafood market is in a densely-populated
district of Wuhan, a metropolitan of ~15 million people. The probability was very low for the bats to fly to the market. According to municipal reports and the testimonies of 31 residents and 28 visitors, the bat was never a food source in the city, and no bat was traded in the market. There was possible natural recombination or intermediate host of the coronavirus, yet little proof has been reported.
Was there any other possible pathway? We screened the area around the seafood
market and identified two laboratories conducting research on bat coronavirus. Within ~280 meters from the market, there was the Wuhan Center for Disease Control & Prevention (WHCDC) (Figure 1, from Baidu and Google maps). WHCDC hosted animals in laboratories for research purpose, one of which was specialized in pathogens collection and identification (4-6).

In one of their studies, 155 bats including Rhinolophus affinis were captured in Hubei
province, and other 450 bats were captured in Zhejiang province (4). The expert in collection was noted in the Author Contributions (JHT). Moreover, he was broadcasted for collecting viruses on nation-wide newspapers and websites in 2017 and 2019 (7,8). He described that he was once by attacked by bats and the blood of a bat shot on his skin. He knew the extreme danger of the infection so he quarantined himself for 14 days (7).

In another accident, he quarantined himself again because bats peed on him. He was once thrilled for capturing a bat carrying a live tick (8). Surgery was performed on the caged animals and the tissue samples were collected for DNA and RNA extraction and sequencing (4, 5). The tissue samples and contaminated trashes were source of pathogens. They were only ~280 meters from the seafood market. The WHCDC was also adjacent to the Union Hospital (Figure 1, bottom) where the first group of doctors were infected during this epidemic. It is plausible that the virus leaked around and some of them contaminated the initial patients in this epidemic, though solid proofs are needed in future study.
The second laboratory was ~12 kilometers from the seafood market and belonged to
Wuhan Institute of Virology, Chinese Academy of Sciences (1, 9, 10). This laboratory
reported that the Chinese horseshoe bats were natural reservoirs for the severe acute
respiratory syndrome coronavirus (SARS-CoV) which caused the 2002-3 pandemic (9).
The principle investigator participated in a project which generated a chimeric virus using
the SARS-CoV reverse genetics system, and reported the potential for human emergence (10). A direct speculation was that SARS-CoV or its derivative might leak from
the laboratory.
In summary, somebody was entangled with the evolution of 2019-nCoV coronavirus.
In addition to origins of natural recombination and intermediate host, the killer coronavirus probably originated from a laboratory in Wuhan. Safety level may need to be reinforced in high risk biohazardous laboratories. Regulations may be taken to relocate these laboratories far away from city center and other densely populated places.

Pandemic Persistence

We labor under a serious misconception that Corona can be eliminated, like polio. The history of pandemics tells us otherwise. The H2N2 virus likely caused the pandemic of 1890. It became the seasonal flu until it was supplanted by H3N2 during the pandemic of 1900. H3N2 was in turn supplanted by the H1N1 virus that caused the 1918 pandemic,which became the seasonal flu until the pandemic of 1957, when it was supplanted by an evolved H2N2. Of course, this became the seasonal flu until 1968, when it was supplanted by a new and improved H3N2 during the pandemic of that year. Vaccination became routine in the U.S. in the 1990’s, but none of these viruses has been eliminated.

The graphic above by Ed Rybiki illustrates this game of virus leap frog. An H1N1 genetically identical to laboratory samples from 1918 caused an epidemic in 1977, but many Americans had immunity. There can be little doubt the critter escaped. Another H1N1 variant caused an epidemic in 2009 that caused fewer U.S. deaths because older Americans still had immunity.

Corona is the new lead dog pulling this sled. It may abate as the weather warms, but it is not going away. We will get antibodies from exposure or vaccine, or succumb. Let’s hope seasonality drums it down and gives us time to develop a vaccine.
