Many of us saw the exaggerated headlines about the “massive heat wave” gripping the USA over the past weekend of 20-21 July 2019:

Well , there is an explanation, it’s called mid-summer.
Climatologically speaking, the two warmest days of the year were this past weekend: July 20 and 21.
Nationwide, Saturday averaged +0.8 F above climatology while Sunday averaged -0.2 F below climatology based on data from the Climate Reference Network:

On Saturday morning, two sites in the Pacific Northwest dropped to below freezing, Stanley ID with 29 F and Meacham OR with 31 F.
And on Sunday morning (21 July 2019) the temperature dropped to 38 F at Great Falls MT, the coldest July temperature of the past twenty years!
Well, here in Oregon, we’ve had a nice mild summer so far.
It was an average summer hot spell. What’s unusual is that kind of heat has been rare last couple summers.
Bias alert!
Citing two days out of this summer to cast doubt on _climate_change_? Please send me more cherries when you are done picking.
Meanwhile, over the past 50 years global _land_ average temp is rising @ur momisugly 0.2C/decade (note: _land_ is higher than _sea_ or _total_. but land is where I live; your experience may differ).
The bias was pretending the weekend was an indication of climatic trend.
Chris, is there some reason you cherry picked the global cooling scare to start your trend? Why not use the best data from satellites and correct for known factors which are not climate related?
Oh yeah, you hate real science. You end up with a trend about 1/3 of the nonsense you spewed.
When are you gonna pay of the debts from the bets you lost, Chris?
I was actually pleased to see little or no alarmism associated with the heat mini-wave. I’m sure it happened, and I don’t doubt that some of you saw it happen, but I didn’t have to roll my eyes once!
There is a massive heatwave every time the temperature goes above 90 in NYC and DC. That is where the media are and anything that happens in their faces is what is important. Anything that happens in flyover country might as well happen in a galaxy far, far away.
Twin Cities MN,
I turned on the air conditioning for four hours this weekend which makes my yearly total, 4 hours.
The morning temperatures for the last couple days have been in the lower 60s (F). My house is well insulated so open windows and fans at night keep the house cool enough to be pleasant all day. This summer has been cool and rainy. Corn crops are 2 weeks or more, less than normal. Nobody wants to buy my motorcycle.
I await NASA telling me I been horribly hot
I like to investigate the NOAA GHCN-Monthly Summary of unadjusted average temps. I know, I know, the TAVG is not the metric to use, but it’s what NOAA provides in monthly summary form, so I’ll look at it.
Here’s the interesting part: if I average each month’s average temp across all of the contiguous US stations, from 1900 to the present, every month but Feb shows a decreasing trend. Feels like I’m doing something wrong, but I can’t find a problem in my logic or my arithmetic.
Lots of “Where I live it is yadda yadda yadda, and has been blah blah blah all year” type comment here tonight.
So here is mine:
In Southern Florida, from early May to early October, it is very hot and very humid every single day.
It is almost never cool or even comfortable outside, unless it is raining heavily, in which case it feels freezing cold, even if you were roastingly hot ten minutes prior.
And sometimes in the early morning between midnight and 6 AM or so it does not feel too bad, as long as you are not moving to fast. But even then if you are wearing long pants and long sleeves to avoid mosquito bites like they recommend, it feels really sticky.
My recommendation is to keep in mind that prior to recent decades, people were always hot in Summer, and usually sticky and sweating, even at night when trying to sleep, unless they lived in a place where it is so cool it is hard to raise a crop, unless of course they were in some magical ideal place where it was just right just about all the time.
Back in the old days, people were typically quite uncomfortable, often hungry, usually dirty, rarely safe and contented, and most commonly in some sort of state of anxiety or fear.
And they liked it!
Right now a cold front is pushing into the state of Florida.
Record low temps are expected across a huge area of the US.
Now, it is for sure that such a push of cool air south will necessarily cause a mass of warm air to surge northwards somewhere else.
How much does anyone want to bet the weather headline of the next several days will barely mention half the continental US is having several days in a row of not just cool but comfortably dry air and that records will be set for how many hundreds of millions of people will have record high comfy index in mid Summer (of course no such index exists), but will instead focus intently on the place where it is of course somewhat hotter than normal?
The odds are 100%.
And it will be mentioned alongside the mentioning of the heat from a few weeks ago, without bringing up the fact that after record warmth in a few spots on a few days, Europe then got very cold, and there was actual frost in July in places like Saxony, a day or two after some places in France had a hot day.
Winter-like jet stream winds across the Western US, noctilucent clouds in the Southwestern US in Summer, feet of snow in Colorado in Summer, snow in New Mexico in Summer, frost in Saxony in mid July…
But these are not headline stories.
The completely normal Summer heat that was in fact very brief and not all that bad by historical standards…those are breathlessly reported and given the appellation of “climate crisis”.
I cannot wait until the climate liar clowns are exposed for the unscientific jackasses they are.
Didn’t James Hansen and a senator pick the hottest average day for the Senate hearing before which they opened the windows to make the air conditioning less effective?
This seems to have helped them add emphasis to their alarm about global warming.
Watch out for the next escalation –
heat thunderstorms!
Sweat – the salt / water osmosis mechanics:
Fish regulate buoyancy by changing body weight. The air bladder always holds the same air mass. Per osmosis the fish can uptake water into the body, the air bladder gets compressed, the fish sinks.
Per osmosis the fish can drain off water, the fish rises in environment.
The control knob for fish / osmosis mechanism is the salt saturation of environment water: drink water / drain off water
________________________________________
Humans use the salt / osmosis mechanism to drain body fluids that evaporates from the skin: thermo regulation.
So regardless of air humidity the body should always be accommodated to air temperatures, provided enough salt uptake.
So the alternatives are: body temperature fitting to environment, REAL temperature observation OR die.
