It Ain't the Heat........



        Half an hour of pulling weeds in 89 degree heat is enough. I’m not really sweaty, though, as I would be most days at 89 Degrees. Thankfully, the dewpoint was just 74 at the time I finished. Also, uncharacteristically, the humidity was a mere 68%.  It was in the 80s yesterday

        
It's (the relative humidity) been running in the low 80s over the past several weeks. That's when the weather report says "temperature is 92, feels like 113!  Our actual predicted high is 104 this afternoon. I Hope the humidity and dewpoint stay low. Why does it matter?  Because it's all about the "feels like!"

        
Factoring in dew point and relative humidity at the time, an outside 89 degrees “felt like” 98, which is 8 degrees higher than the actual temperature, but just about body temperature.  That’s why I wasn’t sweaty, just dirty, when I came inside. Tuesday, on the other hand, on the golf course finishing hole the temp was 92 with a dew point of 80. The “feels like” temperature, that “heat index” they refer to on the TV weather report, was about 110 F.

      
“Dew point” is the true indicator of the total amount of moisture in the air. Most people find dew points of less than 60 degrees comfortable. When the dew point rises above 65 degrees we begin feeling that the air is “sticky.”  As the dew points climb through the 70s the humidity bothers more and more people who are outdoors.

        
 As I said, that whole "feels like" thingy is really the heat index, which is, sometimes called the "apparent temperature." It is a measure of how hot it really "feels" when relative humidity is factored with the actual air temperature. ... As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index (how hot it feels) is 121°F.!    This is also the origin of the "It's a dry heat" saying, because if the temperature is the same 96 degrees, but the humidity is a desert like 25%, the heat index is 94 F. At the same temperature, a 40% increase in relative humidity equates to an apparent temperature 23 degrees higher! Let’s take the ultimate comparison: Phoenix averages less than 40% relative humidity in summer. Orlando averages more than 40% higher than that.

      Deplaning in Phoenix several years ago the outside temp was 113 F. That's hot, but your clothes didn't immediately stick to you because, although it was hot, the heat index was lowered by the low dew point and/or humidity. Right now, , the temperature at Sky Harbor airport in Phoenix is 112 F, but the relative humidity is 11% and the dewpoint is 45.7 degrees. The heat index ("feels like") is 107 degrees. Meanwhile, at the “Magic Kingdom” (Disney World) here, it is 96  F with a relative humidity of 84% and a dew point of 79 degrees. The heat index (drum roll) is between 115 F (using dew point), and 144 (using humidity), which is why there is a high humidity advisory for Disney right now! The calculated heat index usually varies by a degree or two depending upon whether we use relative humidity or dewpoint, but they are usually close. Very high temperatures and humidity will skew the data a bit, as it has today at Disney.

 Using Villages current data at 1 pm local, about 2 ½ hours after I began this, with a lunch break, the temp is 94, humidity is 74% and the heat index is 106 and on the way up. The table below uses only relative humidity and temperature to derive heat index. Results using dew point would be similar except at the extremes. 



Note that the average Southwestern humidity is at the extreme low end of the chart, and the current Phoenix relative humidity (11%) is actually off the chart low.

        That’s what the “dry heat thingy really means. If we hit the predicted 104 degrees and the humidity remains stable at 70% and/or the dewpoint holds at 70, the heat index here will “feel like” between 111 and 113, depending which variable I use for the calculation. Although right now it is 18 degrees hotter in Phoenix than at Disney World, it actually feels cooler. So the next time some sage intones “It’s not the heat, it’s the humidity,” just nod, smile and say, “But what about the dew point?” Cue the crickets.

Stupid Human Tricks

 

This and That, but Mainly Stupid Human Tricks

Off the top:

         Someone I know and love, not immediate family, but a relative, posted the paragraph below as part of a somewhat rambling diatribe about masks, distancing, etc. The implication is that…well, read it for yourselves. My response follows.

“The US Population is 330,000,000 and in 5 months the number of Covid-19 deaths was 156,000. The number of deaths as a percent of the population is 0.00047 %, compared to the number of cancer cases diagnosed in 2019 (1,762,450) and 607,000 deaths.”

This implies, while avoiding a direct statement, that .00047% as many have died from Covid as from cancer. Here’s the problem with leading with that. To begin with, the math is misleading. The Covid annualized death rate for seven months is already 25% as high as the annual cancer death rate! The cancer death toll is .0018%. (Bear with me a moment longer.)  Annualizing the Covid rate to make an apples to apples comparison, Covid, alone will kill about 40% as many Americans in 2020 as all cancers combined!

      Cancer, first of all, isn't a communicable disease! Secondarily, cancer is a generic umbrella for over 100 different (as in distinct and without a common cause) types of aberrant cell growth. Why the underline? Because it’s critical to the validity of the entire argument. If we could avoid or minimize the possibility of contracting all cancer with a mask, no one would leave home without one. 

    Actually, and pathetically, some would, just as some still use tobacco products, even though there is zero doubt of the cancer risk. In fact, lung cancer kills more annually than Covid has to date in the US.)  Those folks (smokers) are the same persons who refuse to wear seat belts, drink habitually to drunkenness (goodbye liver, heart, blood sugar, blood pressure!), and don’t look both ways before crossing. 

        The common mental disconnect factors in these, include 1: “No one’s gonna tell me what to do, I’m an “Amurrican.”  2: denial, because of who knows what illogical personality characteristic. 3: rationalizing it away because it’s not (insert word of choice here, “comfortable”, “simple”, “easy”, “convenient”, “whatever”.) 4. Preferring bad information, while calling real world data “fake news,” because it gives them a “reason” to ignore sound medical advice.

         This is precisely the same mental disconnect as the anti-vaxxers share. Oh, and by the way, in an ironic Karmic twist, cases of Covid are not only more frequent among those in the age 0-15 age group which did not get MMR vaccinations,  but are also more severe, because they lack the innate immune system response. Follow the link below for a far more detailed explanation:

https://bubblehead1026.blogspot.com/2020/07/beware-law-of-unintended-consequences.html

        We, at least those of us with a brain, vaccinate our kids because competent medical advice from the overwhelming majority if physicians says it will prevent childhood diseases which can be fatal, Only radical and  truly fucked up anti-vaxxers oppose these things. As a result, instead of the 15,240 measles deaths in 1935, we see no reported measles deaths since 2015, since, in fact measles was declared eradicated in the US in 2000. Since then with the rise of anti-vaxxers, using the same (possibly fatally) flawed logic of some posts on this thread, we have seen clusters of measles in areas like Oregon where pre school vaccination is optional. So, if you vaccinated your child, but bitch about being as cautions as possible with Covid, your logic circuit is faulty.

And:

        With several major national College football conferences cancelling fall football due to concerns about Covid. Florida Governor DeSantis has urged Florida Schools to continue preparing for a season. This is the same moron who insisted on “opening up” the state prematurely, leading to Florida’s caseload and rate of positives surging to the top of the heap. As a Harvard Law grad and former Navy JAG officer (abbreviated JAGOFF, completely apropos in DeSantis’ case) I had hoped for a sliver of improvement over the former un-incarcerated Medicare fraud perp and also Navy vet, Rick Scott.  Alas, apparently both have suffered brain damage due to extended periods of time with their heads ensconced twixt Donald Trump’s buttocks.  

One final brighter spot:

After being pardoned by Trump,  88-year-old Joe Arpaio decided to run again for sheriff of Maricopa county, Arizona – a post he had held on to for 24 years and lost four years ago amid national outrage over his abusive policing tactics and immigration crackdowns. He lost in the primary, thankfully for Maricopa County, and hopefully as a prequel to even more rejections of Trumpian policy in the rest of the nation.

“Goodbye Joe, you gotta go, me o my o, time to go pole a pirogue down the bayou.” (apologies to Hank Williams) Or just go away.

Even More and More Lies My President Told Me.


                   Even More and More Lies my President Told Me (and you and all of us!)

        Unlike my earlier “lies…etc.” posts, all the prevarications discussed today came from one 40 minute interview ( I prefer the term “burst of bull flatus”) which Trump was stupid enough to do and allow to be broadcast on HBO (Axios filmed it on July 28 and it aired on HBO Aug. 3). I say stupid enough because, if one watches it on HBO, there is no Faux News talking head to explain why the lies are really not lies or a Kellyanne Conway to “walk the statement back” and explain that it is was really not her moronic employer meant to say.

       I’ll start with one of the worst simply because it is vintage Trumpian dog whistle pandering to his White Supremacist base.

"Police have killed white people. In a larger number, police have killed white people."

        This is a vintage Trump deception, generally intended as a defense of the (factual) charge that cops shoot unarmed Blacks at an inordinately large rate. In the absence of context, the statement is true. It is also a favorite claim of the “anti-BLM” folks and is even cited occasionally by Black conservatives. It is actually vintage “ad speak,” in that you never get the contextual data which proves the lie. It’s like the large “40% more flavor” statement on a “new and better” dog food, without the rest of the story which is, “40% more flavor” than what? (cardboard or something else equally bland? You get the picture)

       The context here is everything. While the raw data is accurate, the statistic, as quoted is meaningless.What gives meaning here is the fact that Black people account for just under 13% of all Americans, while 60.4 % self-identify as “White.”  By this metric, if these heinous miscarriages of justice were “color blind”, we should expect to see about 4.6 times as many Whites killed as Blacks. Statistically, that is far from the truth.

       In 2019, 403 white people were shot and killed by police in the line of duty, compared with 250 Black people, according to the Washington Post tally from law enforcement sources. But as the real numbers indicate, the rate at which Black Americans are killed by police is significantly higher. The total number of fatal LEO involved shootings in 2019 was 653. If lethal force had been administered evenly, one would expect just 85, or so, of those deaths to be Black individuals. Reality shows that almost three times that number were killed than their proportion of society should indicate. In truth, I’m not sure Trump even understands the depth of the deception here.

"You can test too much, read the manuals… read the books."

        Of course, Trump is referring to CoVid19 testing here and attempting to defend the real statistic which, as today’s (8/5/2020) news shows, is that the US leads the world in Coronavirus deaths by a sizeable margin with over 155,000. We are just short of 5 million confirmed cases, with about 60,000 new cases repeated daily.

        So where are the lies here? First, “What manuals?”  This from the man who never reads his daily security briefs. I thought this was merely a preference, but as I saw him struggle last night with words like “Yosemite,” (mispronouncing it twice in two attempts) I realize he just doesn’t read well. Trump here is doing what he does so often, which is to make a vague reference to a generic source, the objective of which is to shift blame to a shadowy “them,”  rather than leave it where it should reside.

        The carping about testing is primarily a ruse to divert attention from the fact that Americans, especially Trump’s power base of deplorables, augmented by equally deplorable Fundamentalist Evangelicals who apparently think Covid can be “blown away,” are responsible for the rapid surge in positive cases. One quick daily news example, AP reported: A South Dakota “Christian Youth Summer camp,” requiring apparently little or no concession to the virus, has 96 positives (so far) out of just over 300 attendees. OR The woman in St. Louis who pepper sprayed pizza restaurant employees who asked her to leave because she refused to wear a mask. When the Cheetoh in Chief shills for false cures and eschews the use of a mask for months on end and his sycophants follow suit, it is predictable.

        Of course, none of this is due to Trump’s criminal negligence or abysmal failure to lead, while discrediting actual skilled medical authorities. First, it was due to “The terrible testing rule the Obama administration left us” (Trump, March 4: I just want to add, if I might — and to go a little bit further — the Obama administration made a decision on testing that turned out to be very detrimental to what we’re doing.”  This is/was pure hogwash, but typical of Trump “Obama shaming.”  But now, it’s “that damned testing!”

        "You don’t know" that South Korea had 300 deaths, "and they have spikes."

        To keep this to manageable size, I’ll end with just one more of the many bullshit Trumpian statements from the interview. It begins with a favorite Trump tactic – the implication that he possesses information to which the rest of us aren’t privy, so we should believe it because he says it.  In the case of Covid19 data, Johns Hopkins and others have, from before Trump even really understood the problem, tracked world data and had it available to anyone who cared to look. The “you don’t know” line is meant to make the observer believe that what follows is true and significant.  Neither is categorically true or, moreover, remotely significant true in this case.

       As of today, and as shown for more than 5 months of daily updated data, South Korea’s Covid involvement is available at the click of a mouse. South Korea has (as of today, 8/5/2020) 14,456 confirmed cases and just 302 deaths. That is a death rate per case of .02%. The current US rate of deaths per case is over .03%, so referring to Korea in a negative is ludicrous.

 And since you know I like real data, here’s some Trump “overlooked.”


                                                S Korea                 US 

Population:                             51.6 mil               328 mil

Pop. dens. per square mi.      1366/mi                92/mi

Pop. dens. largest city           42,000!                 27,013    

Ratio of population         328 mil/51.6 mil     US 6.3 times pop         

Number of cases:                  14,466                   4,772,027

Number of deaths:                 302                        156,840   

        Summing up the extrapolations from these real (as in today) figures we see some real eye openers. The first is that the only fair way to evaluate how effectively the virus is being dealt with is to compare apples to apples. So, taking the ration of populations of the US and S Korea, one fact which leaps out is that South Koreans are packed much more closely in the largest city (Seoul), and in fact in the entire nation, with a national population density of  14 times higher than the US. This is partially offset by the fact that we (US) have a lot of wide open and empty space, so comparing population ratios is a far better way to evaluate the data. On that basis the US has 6.3 times as many souls as S. Korea, so we can apply that ratio to S. Korea’s data to legitimately compare how our two nations are doing in combatting Covid.

        Simply put, if I multiply S. Korean numbers by the 6.3 X  population ratio, if both nations are combatting this pandemic equally well, the S. Korean numbers multiplied by 6.3 should equal or at least be close to US numbers.

       Doing the simple math analysis described above reveals a vastly different result. If we and South Korea were having the same success rate, adjusted for population difference, South Korea would have about the same number of deaths (in the vicinity of 156,000), however that number is only 6.3 X 302, or 1903!  Likewise, the number of cases S. Korea would have should be about the same as the US at almost 5 million.  In truth, however, applying the ratio 6.3 X 14,466 yields just 91,136!  

        Reduced to plain language, even with accounting for the difference in population, S. Korea is still doing 52 times better in controlling the number of cases and 82 times better in limiting the deaths from these cases. Like all statistics there are caveats. For these numbers there are several we have to acknowledge. First, the lifestyles of many Americans, from diet to fitness to racial predispositions have an effect on the number of deaths, although not the number of cases. More important, and this is why Trump should have never opened his mouth re: S. Korea, is the fact that as a national policy and as a people, they have responded with leadership and taken sound medical advice to successfully minimize the inevitable  effects of this global pandemic.

         There have been a large number of variables regarding this unprecedented plague which were difficult to analyze and control. Donald Trump and his cohort of science naysayers have failed at the one which was absolutely controllable. If Trump had stressed masks and distancing from the beginning and believed those who touted their necessity, there was high probability that his followers would have complied.  He failed to lead, placing the economy above human lives. Predictably, his more doctrinally slavish political sycophants, such as our moronic Florida governor, have followed suit. The nation is paying the price in blood.
