Being boiled alive in the 101-degree ocean (according to NYT)

by philg

At least five of the folks with whom I chatted in the San Francisco Bay Area recently noted that the ocean water near Florida had been heated up to more than 100 degrees. When I asked them what part of the Florida shoreline was plagued with this scalding water, they couldn’t answer precisely. Their conjectures ranged from a few miles out to sea from Miami to maybe right near a popular beach.

For all of these loyal Followers of Science, one of whom has a Ph.D. in physics, the source was “101°F in the Ocean Off Florida: Was It a World Record?” (New York Times, July 26, 2023):

The reading from a buoy off Florida this week was stunning: 101.1 degrees Fahrenheit, or just over 38 Celsius, a possible world record for sea surface temperatures and a stark indication of the brutal marine heat wave that’s threatening the region’s sea life.

So it’s “off Florida” and therefore out into the open sea, right? If we had any doubt about this, the Scientists at the NYT include a photo of the open ocean underneath the headline:

Based on the headline and the photo, then, a Marvel-style villain heated up part of the open ocean to over 101 degrees and, with a little more climate change, it is easy to imagine this hitting 213 degrees F, the boiling point for sea water. (In other words, New Yorkers with money should not follow their former neighbors and move to Florida because the risk of being boiled alive at the beach is real.)

The best-known beach in Florida is Miami Beach. Is it 101.1 degrees in the water there? seatemperature.net says that, around the time that the NYT raised the alarm, it was a degree or two hotter than the average for previous years:

Maybe “off Florida” meant into the Gulf of Mexico? The water temp on the west coast of Florida was also about average.

Let’s dig for clues in the NYT article:

Allyson Gantt of the National Park Service, which monitors and maintains the buoy, said there was no reason to doubt the measurement. The data was consistent with high water temperatures seen in the area, Florida Bay, between the southern end of the Florida mainland and the Florida Keys, in recent weeks, she said.

Just like it’s easier to heat up a shallow bath than a deep one, the depth of the water is going to affect temperatures, said Jeff Masters, a former hurricane scientist with the National Oceanic and Atmospheric Administration and a co-founder of Weather Underground, a Web-based weather service.

So… it turns out the buoy was not “off Florida”, but rather inside Florida (between the Keys and the mainland). The NYT tells us that shallow water will heat up more than the deep ocean, just as your backyard swimming pool heats up more, but the newspaper of Science doesn’t tell us the water depth.

What’s unusual about the water between the Keys and the mainland? That’s where beginner kiteboarders and windsurfers are taken to learn because (a) the wind is steady, and (b) the water is so shallow that students can stand up after falling off the board. How shallow? The charts show between 0′ and 6′ at low tide:

So the NYT reader was informed that the “ocean off Florida” had reached 101.1 degrees when, in fact, it was a protected area possibly just a few feet deep. (The open ocean off Florida’s Atlantic coast quickly reaches depths of 1,000′ and more.) Is Florida Bay even part of the ocean? Wikipedia says that “It is a large, shallow estuary that while connected to the Gulf of Mexico, has limited exchange of water due to various shallow mudbanks covered with seagrass.” (What’s an estuary? Wikipedia says “An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.”)

A Bay Area Deplorable (deeply closeted so that he can keep his job!), when I shared these conversations with him, said “when you’re looking at the New York Times, what you don’t see is more important than what you do see.” (i.e., the unseen depth of the water and the unseen previous buoy high temp in the same area are more important than the seen recent high temperature)

When I got home on August 3, 2023, I discovered that the lifeguards on the Atlantic coast hadn’t been reading the New York Times. They marked the Juno Beach water temperature as 85 degrees:

In case the NYT article gets memory-holed, some screen shots:

Note that the article also mentions “Manatee Bay” as a place where the “ocean” is super hot. Here’s the open ocean in Manatee Bay, from Google Maps:

How deep is Manatee Bay? 4-5 feet, except where mud or coral makes it shallower.

Why does it matter? If you’re ordering a 150-meter boat from Meyer Werft, make sure to tell them it can’t draw more than 4′ (or 1′ for Florida Bay?) because you want to sail it in what the New York Times calls “the ocean”.

How did the crippled-by-Long-Covid Swedes beat the American soccer world champions?

by philg

We are informed by the New York Times and CNN that Long COVID is (a) crippling, and (b) almost inevitable for those who reject Faucism. Sweden is renowned for letting SARS-CoV-2 rip through its younger-than-70 population while the elderly hid (excess mortality data by country). The Swedish women’s soccer team doesn’t contain anyone over age 73 and, therefore, must necessarily be riddled with Long COVID. How do we explain “Knocked out. Sweden bounces top-ranked U.S. out of the Women’s World Cup in penalties” (state-sponsored NPR) then?

It can’t be that the world champions are also Covid-plagued. From summer 2020, “Megan Rapinoe one of three internationals to withdraw from NWSL Challenge Cup” (BBC):

Forward Christen Press and midfielder Tobin Heath will not play because of “uncertainty” caused by the virus.

“Megan let us know that she has decided not to play,” said Bill Predmore, chief executive of Rapinoe’s team OL Reign.

“Like all NWSL players, she was given the option to participate … but we understand and respect her decision.”

The tournament, being played in empty stadiums, starts on Saturday in Utah and will last for one month.

Star players also cowered in their bunkers in the fall and winter of 2020… “NWSL star Megan Rapinoe says she won’t play in fall series” (CBC):

Two-time World Cup winner and OL Reign midfielder Megan Rapinoe is opting out of the National Women’s Soccer League (NWSL) fall series starting next month, the Washington-based franchise said in a statement.

No reason was given for her decision but Rapinoe, 35, also skipped the NWSL Challenge Cup tournament in June, which was played in empty stadiums due to the COVID-19 outbreak.

Rapinoe sang the praises of lockdown in the Journal of Popular Studies:

Megan Rapinoe on Quarantine Life with New Fiancé Sue Bird: ‘It’s Been Such a Gift’

“Because we’re athletes, we’re constantly on the go and we never get to spend this much time with people that you love,” Megan Rapinoe tells PEOPLE in this week’s issue

So… the soccer players who were out and about in 2020, exposed every day to dangerous levels of SARS-CoV-2, beat the soccer players who wisely cowered in place and thus were protected from Long Covid and the even-more-dangerous Medium Covid. How can this fact be squared with Faucism?

Loosely related… an open-to-all-genders single-city team of 14-year-olds beat the world champions prior to coronapanic (CBS):

Also… “Djokovic Heads Hard-Court Leaderboard” (from the gender-neutral ATP Tour, 6 days ago):

Novak Djokovic has dominated the ATP Tour’s hard courts throughout his career, and the past 52 weeks are no exception for the 36-year-old.

Across a run that includes titles at the 2022 Nitto ATP Finals and the 2023 Australian Open, the Serbian has posted a tour-leading 91.9 per cent win rate (34-3) on the surface during that span. He also won hard-court titles in Tel Aviv and Astana last year as well as at the Adelaide 1 event to start the current season.

How is it possible for someone who was infected with SARS-CoV-2 without a previous vaccination to be the world’s best hard-court tennis player?

Also related, “The social justice of coronashutdowns” (January 2021), in which a friend who lives in a $9.6 million house (pre-Biden money) disagrees with my assertion that “[school] shutdowns are ordered by people who live in mansions (governors) and supported by rich white people who live in 4,000+ square foot suburban houses” and therefore don’t consider “a single parent in a 2BR public housing apartment with three kids” and “what benefit the shutdown is delivering to a 30-year-old single mom and her 10-year-old kids”.

Infrared versus regular gas grill? (and what about electric?)

by philg

We’re getting ready to run a natural gas line to where our gas grill is ($1500 is the new $700 for a half day of plumbing effort). We’ll need either to convert our basic propane grill, now 1.5 years old, or buy a fancy new grill. The space is tight and a grill wider than about 50 inches won’t look right (even the smallest grills are about this size with side shelves). We go through a propane tank every 1-2 months (using the grill every other day).

One of the divides in the consumer grill world seems to be infrared vs. conventional. The IR enthusiasts claim that they get better sear marks after a faster heating time and the reduced amount of hot air flow keeps more moisture in the food. On the other hand, some of the higher-end grills either don’t have an infrared burner or reserve the infrared burner for rotisserie, or have an infrared burner as a specialty zone with most of the grill being conventional. Here’s a grill that I overheard one rich guy recommending to another rich guy:

It has “Rotisserie system with infrared burners” but the primary burners are conventional. (Why would anyone pay $34,000 for a freestanding grill? The product lets you stick charcoal or wood in and light it with the gas. You can also do it with a $1500 Canadian grill from Napoleon and an accessory tray if a $32,000+ savings is significant to you.)

TEC sells $4,000+ infrared-only grills and claims that they’re vastly superior in every way. Certainly nobody is going to steal one because their smallest model weighs 248 lbs. on a pedestal. If TEC is so great, why don’t all of $1000 grill brands copy them? “Advantages and Disadvantages of Infrared BBQ Grills” says that infrared is unconditionally better:

Clean up is easier, too. The high temperatures practically vaporize any drippings or unwanted mess. In fact, most infrared grills are designed to use this feature by collecting the drippings in a channel. They’re then vaporized back into the food as pure flavor, eliminating the fare-ups in ordinary grills that must be conquered to avoid burning the food. These channels just wipe or clean with a regular grill brush. This is because of the high radiant heat.

Finally, food actually tastes better on an infrared grill, according to many. This is due to the high temperature and direct heating. The infrared burners are wide and cook uniformly with even heat distribution. It locks in all the seasoning and natural flavors in your food. The quickness of the neat locks in moisture, too. Meat, seafood, vegetables – everything is quickly seared and flavor-locked for the best taste.

“Infrared Grills — Advantages, Disadvantages and How They Work” says that the disadvantage is an ability to cook at low temps:

Although an infrared grill could take your steak cooking skills to another level, popular opinion is that this is about all it will do. With the crazy high temperatures it can reach, the grill can be somewhat difficult to master when it comes to the time-temperature relationship. In addition to this, it doesn’t offer the lower temperatures that a traditional gas or charcoal grill does. In contrast, other more traditional grills can offer as low as 100f at the low-end, which is great for slow cooking meats, whereas an infrared grill only goes as low as 250f.

(the TEC people claim that they can now go down to 200 degrees)

This retailer page suggests that infrared is not the complete solution.

To prepare for climate change, in which our 3-mile-inland house will soon be at the beach, it might be good to get a grill made from 316L marine grade stainless. Here’s one from Blaze into which an infrared burner can be installed to replace one of the conventional burners (about $4,000 total and we’d need to lose one side shelf to make it fit).

Readers: Have you cooked on an infrared grill? Is it suitable for nearly all grilling projects?

Crazy/heretical idea: If infrared is truly the best technology, why bother with natural gas or propane? Why not run a dedicated outlet, either 120V or 240V, and use electricity to create as much heat as desired? Char-Broil sells what they claim is “TRU-Infrared” for 320 square inches for $250. That’s actually larger than the 296-square-inch grilling surface claimed by TEC for its $4,000+ product. (Food&Wine magazine says that it doesn’t work) If you don’t need infrared, then a Ninja outdoor electric grill for $330 (you can toss in wood pellets for authentic smoked flavor), which gets 4.7 stars on Amazon. An electric grill used for slow-cooking should be vastly simpler and more reliable. Instead of adjusting the knobs and monitoring, set the desired temperature and walk away for 5 hours. Maybe gas grills are obsolete, just as gas ranges in the kitchen are obsolete, having been slain by mighty induction! (as predicted by Katherine Clerk Maxwell’s Equations) There aren’t that many full-size electric grills available right now, but we’ve been doing fine with 320 square inches of cooking surface on our existing grill.

(Existing electric grills don’t seem to make any attempt to compete with gas grills for total heat output. A medium-size standard four-burner grill puts out 48,000 BTUs, about 14,000 watts. The highest wattage electric grills that I have seen are 3,000 watts, less than a single burner on a high-end induction cooktop (3,300 to 3,700 watts is typical).)

Here’s a piece of restaurant equipment that I discovered at a friend of a friend’s house:

It seems to be called a “salamander” and the claim is that it will heat up to 1050C. It is all-infrared-all-the-time Based on a quick search, they seem to start at about $4,000 and consume 3000-4500 watts. (The house that I visited contained not a single piece of kitchen equipment that I knew how to either turn on or use.) More background on salamanders: from a retailer; from a manufacturer.

Loosely related (on the advantages of a propane-free society)… a story about Mohamad Barakat, a successful asylum-seeker from Syria:

Firefighters notified police [in Fargo, ND] after seeing guns, ammunition and propane tanks in Mohamad Barakat’s apartment, according to a report provided to The Associated Press Wednesday by the City of Fargo Fire Department.

Battalion Chief Jason Ness noted what appeared to be “a significant amount of gun ammunition,” “multiple ‘assault style’ rifles,” a 20-pound propane cylinder in a bedroom, a second smaller propane cylinder in the kitchen, and “a funnel, blender, and other items that looked to be for measuring purposes” in his report on the Sept. 6, 2022 fire.

“FPD determined everything was legal with the gun collection,” Ness wrote. “The individual admitted to owning approximately 10 guns and 6,000 rounds of ammunition. My decision to refer the issue to PD was based on the presence of the guns, several high capacity magazines, and the presence of propane tanks with no means of using the tanks for cooking or grilling.”

The migrant-turned-U.S. citizen loaded up the propane tanks a year later: AP News.

Climate resilience and Oshkosh (EAA AirVenture)

by philg

Attendance at “Oshkosh” (technically, EAA AirVenture) seemed lighter than in 2021 and 2022, possibly due to the weather being about 10 degrees F hotter and the first couple of days being marred by poor air quality courtesy of our Canadian neighbors. (EAA says that attendance was actually a record, contradicting our lived experience.) The EAA Lifetime Member “Oasis” was nothing of the sort, due to A/C that couldn’t cool the place down below 80 degrees. The typical GA plane, warbird, or vintage/antique lacks A/C and, therefore, people had trouble getting motivated to do intra-event flying.

Given that people have less tolerance for discomfort every year (central and mini-split A/C having grown in popularity) and that we’re assured by the New York Times and CNN that Planet Earth is going Full Venus, I wonder if it wouldn’t make sense to move the fly-in to early June. The public schools in Oshkosh get out on May 31, 2024, thus freeing up the no-A/C school buses that are essential to the EAA event. Why not fire up EAA AirVenture on June 10, 2024? Here are the weather averages by month:

June is 5 degrees cooler than July (though records for June 10 include some 90-degree days in various years; record temp for June 10 is 94). Given the higher heat in July, one might imagine that it is also the peak time for thunderstorms, hail, and tornadoes. Here’s a warning that we got:

OSHALERT 7/27: NWS issued Severe Thunderstorm WATCH for KOSH until 11pm. Could bring 1-2″ hail, 70mph winds, heavy rain, isolated tornado.

When basic new airplanes cost about the same as Corvettes and thousands were produced annually, perhaps a mass casualty hail event at KOSH wouldn’t have been so bad. But now that new piston four-seaters can be over $1 million and parts can take months to obtain, the risk of losing 10,000 planes has to be given more weight. From my web searches, it looks like June is actually a higher risk month for tornadoes and severe thunderstorms than July.

If the event can’t be moved, perhaps it can be made more comfortable. EAA has over $44 million/year in revenue (see Form 990; note that this was down to just $18 million in 2020, AirVenture having been canceled due to lockdowns). How about spending some of that $44 million on A/C for the four vendor hangars and also on some air-conditioned lunch venues scattered around the grounds? While EAA is at it, build some additional permanent running-water bathrooms around the show grounds and bathhouses (not Florida-style, necessarily) in campgrounds. Porta-potties and trailers don’t make for a luxurious experience. EAA is constantly harping on how they want to get more people who identify as “women” to show up. How many women want to use an outhouse for 7 days? And women with kids? Imagine the mom below trying to manage and clean up her 3 young kids in porta-potties:

Airparks I learned about at Oshkosh

by philg

The young aviator dreams of having his/her/zir/their own plane. The old aviator dreams of living at the airport. One thing that I enjoy at Oshkosh is learning about new airparks. The one that seems to have the most promise for Florida residents is Big South Fork Airpark, which offers through-the-fence access to a public 5,500′ runway in personal-income-tax-free Tennessee just north of Knoxville. KSCX is indeed right next to some mountains, but the “numerous strip mines” note on the chart is concerning:

The sales reps said that lots are about $150,000 and their approved local builders can create a nice house for $200 per square foot ($500/ft. is more like it in South Florida!). Here’s the plan:

An instrument approach to this runway gets down to about 250′ above the runway and requires only 1 mile of visibility. When the runway needs repaving, the FAA will pay for it out of aviation fuel taxes that pilots and aircraft owners are already paying.

For pilots in the frigid Northeast, Kaynoa in the Dominican Republic might be a more attractive choice. It’s a 4,000′ runway and the homeowners will have to pay to repave it. The renderings look good! (Flying has an article with some photos of what it actually looks like.)

Speaking of Flying, their own project’s web site still says “coming in 2023”. This airpark is near Chattanooga.

(Note that Floridians enjoy much stronger protection against a state personal income tax, which is barred by the state constitution, than do Tennesseans. If a future legislature/governor pair in TN decides that more revenue is needed, nothing would stop the state from imposing an income tax.)

The New York Times said that the temperature outside was up around 125 degrees (see Floridians brave Extreme Danger heat levels), but, thanks to Florida Power and Light and inventor Jennifer Carrier, we were comfortable inside.

A humanist looks at Sweden v. Covid

by philg

For us numbers nerds, here’s an interesting thread from Daniel Hadas, a medieval Latin professor in London who describes himself as a “Catholic humanist”… “Some remarks on Covid and Sweden.”:

… what matters is that life in Sweden during Covid continued largely as normal.

Lockdowns are deeply unnatural. They do not happen without intense social pressure, whether it be through legislation or propaganda. That pressure was absent, or at least muted, in Sweden.
At this point, it is customary to start arguing about statistics. Anti-lockdowners point to Sweden’s low excess mortality. Pro-lockdowners point to the number of Covid deaths, or to unfavourable comparisons with some of Sweden’s neighbours.
But there is no need to look at statistics to draw the essential conclusion about Sweden’s response. Any innumerate peasant can draw it, and indeed it is only those whose sense-making relies on statistics who can think some more potent conclusion lies hidden in them.
The essential conclusion is: 𝘯𝘰𝘵𝘩𝘪𝘯𝘨 𝘵𝘦𝘳𝘳𝘪𝘣𝘭𝘦 𝘩𝘢𝘱𝘱𝘦𝘯𝘦𝘥. Sweden’s health system did not “collapse”, whatever that means. Stockholm does not look like Athens after the plague. Sweden is as Sweden was.

No numbers are needed to prove this.

In other words, numbers nerds like me are useless!

Thus Sweden, like every other jursidiction that did little in response to Covid, gives the lie to all the modellers and panic-mongers who screamed at the public that there was 𝘯𝘰 𝘢𝘭𝘵𝘦𝘳𝘯𝘢𝘵𝘪𝘷𝘦 to shutting down society, that every extreme measure taken was not enough.

Maybe Hadas disdains numbers because he can’t think with numbers? Actually he can!

It is ludicrous to maintain that, via statistics, certainty can be established on the causal link between a country’s anti-Covid measures, and the number of deaths in that country. The system we are trying to analyze is vastly complex: the whole of society, over several years. The potentially confounding variables are therefore countless. The effects being sought are small.

I made the following point back in 2020, but he does it more succinctly and eloquently. The majority of Americans assumed that a society with a lower Covid-tagged death rate was superior to a society with a higher Covid-tagged death rate. But that can be true only with some value judgments.

… behind the policy language of “a country’s response to Covid” lie questions for each individual: Should I lock up my children for 23 hours a day? Should I leave my parents to die alone? Should I not touch another man or woman for months on end? … The answer to these questions is not to be found in numbers.

The Swedish response to Covid was right, because, or in as much as, Swedes answered such questions in the negative. The only true disaster threatening us in the Covid years was answering them in the affirmative.

Maybe more people should study medieval Latin!

And because I’m not a humanist, but a numberist, let’s check the numbers:

and here’s the curve (of excess deaths) for Ireland (picked as a comparison country for Sweden by the NYT):

Hunting down an air handler fan that is running too slowly and growing mildew (breaker panel power monitor)

by philg

I’ve been trying to reengineer the air conditioning in our house to match the new(ish) reduced cooling load after a hurricane low-E glass window retrofit by the previous owner (see ChatGPT is almost as bad at home maintenance as I am). Before I downsized the system, however, I decided that I had better make sure that the theoretical Manual J calculations of an 8.5-ton demand were correct. The goal was to see what percentage of the time the 12-ton current system (divided into three condensers/air-handlers) was running on hot days (e.g., when the NYT says South Florida is facing EXTREME DANGER).

I decided to install an inductive current monitor in the circuit breaker panel that could watch all three air handler breakers, specifically the Emporia Vue 2. This is supposed to be easy to install oneself and I have a Ph.D. in Electrical Engineering… so I decided to hire an electrician to do it properly. It took him less than one hour and he never shut off power to the panel, as the instructions suggest.

The software is reasonably good, but setup operations take longer to complete than you’d expect. Budget perhaps 30 minutes to get it all connected to WiFi and then to rename the ports. Here’s our Air Handler 3, a 3-ton system, on a day that was 125 degrees (NYT) or 91 degrees (Google/Apple). We can see that the variable-speed air handler (sadly, connected to a one-speed condenser) ramps up to about 500 watts and also that it is running most of the time (the calculated current demand for the upstairs was just 2.3 tons).

Here’s the a 5-ton air handler:

It’s drawing only 100 watts. Notice that I called it “AH2Try2” because I replaced the probe (myself!) and connected it to a different port because I assumed that the Emporia device was bad.

The installation guide for the Trane TEM6 air handler says that it should be drawing at least 500 watts:

I found that the unit was sweating on the outside and, opening it up, mildewing on the inside. The A/C contractor did the following:

  • replaced the blower (covered under warranty by Trane)
  • took the air handler apart and cleaned it
  • pumped out the refrigerant and cut the evaporator coil out and brought it down to the side yard and cleaned it thoroughly
  • cleaned out the air handler interior
  • replaced the plenum
  • replaced a failed UV sterilizer that had been in the old plenum with a REME HALO

With the new fan in place, power consumption went up to over 700 watts and the cabinet stopped sweating.

Given that air handlers are hard-wired, I don’t know of any other way to verify that they’re working properly. The regular A/C service guys don’t measure airflow carefully. And the power monitor is fun to have for investigating random appliance power consumption questions. Our 20-year-old last-legs KitchenAid refrigerator is consuming only 75 watts, for example.

What if you don’t want to spend $250-ish, including an electrician’s time? You can spend $thousands to replace your whole breaker panel and/or all of the breakers with “WiFi breakers”. Span will sell you a panel for $4,500 (plus the breakers?). Can you guess where this new company is located?

Eaton, which has been making panels for about 100 years, sells individual WiFi breakers that can report consumption and also be reset remotely. These seem to cost about $250 each, but if you already have an Eaton panel the installation could be cheap and simple.

Leviton makes a comprehensive system, but it will require replacing your panel(s). The panels themselves from Leviton seem to be cheap (less than $200). Once that’s done, an individual breaker can be as cheap as $54. Our electrician put this system in his own house and likes it.

Speaking of breakers, how long do they last in your experience? Our panels have spent 20 years in a hot/humid garage and the Cutler Hammer breakers inside don’t seem to be happy about it. Especially if a big one trips or is toggled it will tend to require replacement.
