Fifth National Climate Change Assessment Propaganda “Science Report” Released

Guest essay by Larry Hamlin

The White House has released the Fifth National Climate Change Assessment report providing the country the latest government hyped climate alarmism science propaganda updates as noted in the news article excerpts discussed below.  

The Associated Press highlights the following “even clearer evidence” that now exists since the last government science propaganda report 5 years ago:

“The climate change signal is “even clearer today than it was five years ago,” Hayhoe said. In the U.S., people across all regions are experiencing hotter temperatures and longer-lasting heat waves, with nighttime and winter temperatures warming the fastest.”

The L A Times highlights among the other “usual suspects” of climate alarmism hyped propaganda the following:   

“Anyone who willfully denies the impact of climate change is condemning the American people to a very dangerous future. Impacts are only going to get worse, more frequent, more ferocious and more costly,” Biden said.

Tuesday’s assessment paints a picture of a country warming about 60% faster than the world as a whole, one that regularly gets smacked with costly weather disasters.”

Looking at the latest available NOAA National Time Series update that provides detailed maximum temperature data for the monthly Contiguous U.S. Maximum Temperature measurements from January 1895 to October 2023 (shown below) we struggle to see where the huge increase is happening in “experiencing hotter temperatures” and where the “warming” growth rate “60% greater than the world as a whole” is taking place because the measured data says those claims are nothing but climate alarmist contrived propaganda.

The NOAA data establishes that the highest maximum temperatures in the Contiguous U.S. occur in the month of July with all July monthly maximum temperature measured data show below for the period from 1895 to 2023.

Furthermore, the maximum monthly temperatures ever recorded in the Contiguous U.S. during the period from 1895 through 2023 occurred in July 1936, July 1934, July 1901, July 2012, July 2006, and July 1931 as shown below with these measured results making a mockery of the contrived “60% greater warming growth rate” climate alarmist hype.

 Looking at NOAA California monthly maximum temperature data (shown below) from 1895 to 2023 in pursuit  of “warming“ growth rates “60% greater” than the world as a whole we find no  measured scientific evidence supporting these contrived climate alarmist hyped claims.

California’s maximum monthly temperature recorded data shows that July 1931 (by 1.4 degrees F higher than the next highest maximum) was the highest ever measured temperature as shown below from NOAA’s measured data.

The climate alarmist L A Times published this government propaganda “science” update report on page 1 as shown below.

The Orange County Register placed this ridiculous climate alarmist update report buried on page 10 (lower left article) where this contrived propaganda garbage “science” report belonged as shown below.

From the above article:

” ‘Anyone who willfully denies the impact of climate change is condemning the American people to a very dangerous future. Impacts are only going to get worse, more frequent, more ferocious and more costly,’ Biden said.”

Hmmm . . . count me as standing proudly among those who you condemn. I can easily take such bullsh*t.

Now, having said that, do you, Joe Biden, have any scientific proof preponderance of evidence—in fact, any scientific evidence at all—that the rest of what you spouted forth is true?

Oh, and FYI, “climate change” has been happening on Earth continuously for some 4.5 billion years,usually with extraordinary impacts.

And I can’t imagine anything more “ferocious” than the climate change that wiped out something like 90% of all living species on Earth over a period of 60,000 years centered on some 252 million years ago, at the end of the Permian period.

In 1989 the UN predicted entire nations would be adversely affected if the supposed warming trend weren’t reversed within a decade. It also claimed that all of humanity had until 2000 to solve the greenhouse gas effect before it went completely out of control. So here we are, a third of a century past those forecasts with populations, life expectancies, and agricultural outputs all increasing. Did something go wrong or was it the old story of most of the planet ignoring the alarmists and their histrionics

The solution to EV car fires has been solved. Everyone can now buy a EV/Hybrid with piece of mind. No longer do you need to be concerned about you and your family being trapped by fire in your house, parking structure, ferry, or what ever.

The EV Fire Blanket is here.

Insurance Companys intend to require EVs be wrapped in this blank at night

These blankets will be prepositioned on all public roadways, bridges, and parking structures

Any one using a ferry will be required to carry one in their trunk and carry a training certificate

The UN is considerationing the required use on all EVs being shipped across international waters.

The world is saved.

Hmmm . . .my understanding, limited as it is, is that the “EV Fire blanket”:
a) does not prevent EV battery fires from spontaneously occurring,
b) does not extinguish EV battery fires, and
c) only reduces the chances that the EV battery fire spreads to an adjacent vehicle or structure.

Therefore, probably worth $4.99, assuming one can purchase one at that price.

The lithium is involved in a chemical reaction that does not require O2. The blanket would smother other material that burns using O2. A Li bat in a small phone charger recently caused a fire on a plane….water was dumped on it but the water is just for any material that the Li fire caused to start burning….Li reacts with water…..Elon does not talk about Li fires….just the acceleration of his Teslas and how the Teslas do not roll over easily.

Removing the blanket from a burning vehicle, preparing it close by then moving alongside and tucking it in is not the safest place to be with an EV fire.

There are many videos showing enormous jets of flame coming from these cars when on fire plus the smoke is toxic

The Congressionally mandated NCAs are the joint work product of 19 federal agencies. All of which have a vested interest in receiving more climate funding from Congress. So naturally they produce NCAs that require more climate funding for themselves. Similar to Mafia protection racket shakedowns.
Their ‘only’ problem is that their obviously biased assessments are easily refuted by readily available facts, as here.
The old Soviet PRAVDA probably had more truth than any NCA produced by USG.

November 16, 2023 3:31 am

Thanks for all the constructive criticism of the national data.

I used 1970 as a starting point, as that’s roughly the time when modern global warming started. It’s also the starting point the assessment using when it’s comparing global to national warming.

Of course if you look at the entire data set starting in 1895, you see a slower rate of warming, just as you do globally.

For annual max data, this is 0.08°C / decade, compared with NOAA’s global average data over the same period of 0.09°C / decade.

If you restrict it to just July, the US max data drops to 0.05°C / decade. This has a lot to do with the climate emergency the US was suffering in the 1930s.

Hansen’s chart of U.S. temperatures (Hansen 1999) shows 1934 to be warmer than 1998/2016.

Why doesn’t your graph show this?

Reply to  Tom Abbott
November 16, 2023 7:16 am

Why doesn’t your graph show this?

Short answer – it does. Annual maximum temperatures in the NOAA data are 66.76°C for 1934 and 65.63°C for 1998. 1934 is around 1°F warmer, which is similar to the 0.5°C difference shown in Hansen’s graph.

Of course, his graph says nothing about 2016, given it was produced two decades before we could have known how hot 2016 would be. Even so, NOAS’s graph shows 2016 as being 66.69°C – still insignificantly cooler than 1998. You may be confusing this with 2012, which is the warmest max year in the NOAA series, at 67.69, almost 1°F warmer than the second place 1934. Again for some unknown reason Hansen failed to include 2012 in his data set produced in 1999.

Of course, it should be said that these graphs are not showing the same thing in any case. My graph is for maximum temperatures where as Hansen’s is for average ones.

If you look at average temperatures, 1934 is very slightly cooler than 1998, and there have been several warmer years since then. The 1930s had hot days, but also cooler nights, it would seem. Also some cold winters.

Why the 1999 graph shows a bigger spike in 1934, I couldn’t tell you. As always I think it’s a mistake to look at anyone graph as being the one true vision, and therefore any other graph is wrong. Much better to look at a range of graphs as an aggregate of knowledge. This is especially true when one of the graphs is a quarter of a century old.

“Of course, his graph says nothing about 2016”

His graph doesn’t have to say anything about 2016.

According to UAH, 1998, and 2016 are within about 0.1C of each other which makes 2016 cooler than the 1934, by about 0.4C

Reply to  Tom Abbott
November 18, 2023 5:19 am

“According to UAH, 1998, and 2016 are within about 0.1C of each other”.

According to UAH, 2016 was 0.2°C warmer than 1998 in the US, and 2015 and 2017 about 0.16C warmer still.

But you can’t compare UAH and satellite data with a 25 year old surface data set. You don’t know what Hansen’s method would have said about 2016, or what UAH would have said about 1934.

As always you seem to be hung up on the idea that Jim Hansen in 1999 was capable of producing infallible data, and any other data set that doesn’t agree with it must be wrong. Except you also think Hansen’s 1999 global data set is also wrong because it doesn’t agree with his US data set.

What you see is recent warming during the 1970’s preceded by a 45-year cooling trend from 1934 to 1979. Is recent warming a rebound from the cooling? Who knows? But it refutes the claim that CO2 is the main cause because CO2 has increased steadily over the last century but temperatures have both cooled and warmed over the same period, apparently indifferent to CO2. What happens in the next few decades is a guess, based on the variability of the last century.

Because that’s roughly when global warming started. It’s also the start point used in the assessment when comparing US and global temperatures.

As I say above, you can look at all the data since 1895 and get similar levels of warming for the US and global. But that’s trying to fit a linear trend over not very linear data. And of course, the US had it’s own problems in the 1930s which skew the comparison somewhat.

The maximum monthly temperatures ever recorded in the Contiguous U.S. during the period from 1895 through 2023 occurred in July 1936, July 1934, July 1901, July 2012, July 2006, and July 1931 as shown below with these measured results making a mockery of the contrived “60% greater warming growth rate” climate alarmist hype.

While it’s certainly impressive that someone believes six individual months can somehow single-handedly debunk well-established climate science trends, it might be helpful to remind them that statistical analysis would generally form the basis of credible counterpoints in this situation.

Since the alarmist government report claims that U.S. temperatures have been “climbing 60% faster than elsewhere on earth” and that our citizens are experiencing “hotter temperatures” why would the “highest ever” measured U.S. temperatures have occurred in the 1930s? “Statistical analysis” isn’t needed when the answer is as obvious as this data clearly shows particularly when the exaggerated temperature claims are nothing but alarmist hype in the first place.

“climbing 60% faster than elsewhere on earth” “

OK, since 2005, when USA temperatures were measured in a reasonable way and at reasonable surface sites, the average trend of satellite (UAH-USA48), and surface (ClimDiv and USCRN), is about 0.02ºC per year.

That means that “elsewhere on Earth” is warming at 0.0125ºC/year.

@Gorilla R… it is important to note that trends from 1895 to about 1945 were increasing, from 1945 to 1975 or so, they were cooling and since 1975 they are increasing again. The earlier rate of increase is approximately the same as the later increase… and the majority of the maximum recorded temperatures were before the 1940’s. Claims that this July was the warmest “evah” are balderdash.

Yes, they are.

Debunk this U.S. temperature chart (Hansen 1999):

I see a longterm warming trend beginning in the 1910’s culminating in the warmth of the 1930’s, then a longterm cooling from the 1940’s to the 1970’s, and then a longterm warming from the 1980’s to 1998 (the limit of this chart).

So it isn’t just a few individual months that show the picture.

The discrepancy between the graph you show and updated version of the graph is the result of a time of observation bias adjustment and pairwise homogenization.

It’s supposedly the reasoning for those adjustments.

So.. thanks for verifying the change is because of FAKED adjustments.

Not helping your cause.

Emphasis on the word ‘supposedly.’ I don’t subscribe to the idea that the adjustment is valid; I just know that’s the reason for why the trend turns from cooling to warming.

“The discrepancy . . . is the result of a time of observation bias adjustment and pairwise homogenization.”

You mean “they” haven’t yet applied “adjustments” for:
— change in temperature monitoring instrumentation accuracy/calibrations that occurred from 1880 to ca. 1998?
— change in temperature monitoring station site locations and instrumentation enclosures that occurred from 1880 to ca. 1998?
— increases in the number of temperature monitoring sites that occurred from 1880 to ca. 1998?
— impacts of UHI bias in reported temperatures of a significant number of temperature monitoring sites from 1880 to ca. 1998? (This obviously excludes all temperature monitoring stations comprising the USCRN, which only began being implemented around 2001 and was declared “complete” in 2008)?
— human changes in Earth’s surface albedo that have occurred from 1880 to ca. 1998 . . . you know, those due to deforestation as well a use of cultivated land for large scale agriculture
— changes in percentage of atmospheric cloud coverage that may have occurred from 1880 to ca. 1998, as overall global climate has changed over that interval?

Looks like “updating” has left out many, many important things.

There, fixed it for you.

“The climate change signal is “even clearer today than it was five years ago,” Hayhoe said. In the U.S., people across all regions are experiencing hotter temperatures and longer-lasting heat waves, with nighttime and winter temperatures warming the fastest.

That’s called UHI.

That’s also called Hayhoe climate propaganda.

The climate change signal may be clearer to her, but there is still no evidence there is a climate change signal.

Hayhoe sees what she wants/is paid, to see.

Hayhoe is doing her usual job of distorting the truth about CO2 and the Earth’s climate.

If you see Hayhoe is involved, expect an “it’s worse than we thought” commentary. That’s her job.

Exactly! Look at who pays Hayhoe for her “services”. Then look at their not-so-hidden agendas.

I’m still having trouble with the following NOAA chart for Wokeachusetts. How can it range from 46F one year to 56F another year? This is what the state is using to push all the alarm bells. Could the annual average temperature really change that much? Up 12F???

“Could the annual average temperature really change that much? Up 12F???”

Sure, it could.

“Massachusetts sees a wide variety of temperatures throughout the year, the average being as high as 95 °F (35 °C) in the summertime, and as low as -8 °F (-22 °C) in the wintertime.”
https://en.wikipedia.org/wiki/Climate_of_Massachusetts

You’re inquiring about a variation of 12 deg-F in year-to-year averages, when the variation within a single year is typically about 103 deg-F: a ratio of about 1:8.5.?

Seems reasonable to me.

Of course the temp throughout the year varies tremendously but the annual average temp? They are two very different things- so doesn’t seem reasonable at all.

Actually, your extreme numbers aren’t correct. I’ve experienced 105F and as low as -22F.

Reply to  Joseph Zorzin

1) Not my numbers . . . Wikipedia’s

2) Wikipedia explicitly stated sated: “. . . temperatures throughout the year, the average being as high as 95 °F (35 °C) in the summertime, and as low as -8 °F (-22 °C) in the wintertime.” (my bold emphasis added)
In contrast you seem to refer to a particular peak high and a particular peak low.

Reply to  ToldYouSo

Since my particular high and low are different- that means Wikipedia is wrong- which is something you apparently can’t grasp. And my numbers aren’t that rare. It gets over 95 most years. I haven’t see it as low as I mentioned- that was 40 years ago- but it can happen again. I’d say -8 is often the lowest for most years.

“. . . which is something you apparently can’t grasp.”

Hmmmm . . . that would be the logical fallacy of an ad hominem attack.

It’s sad to see you felt the need to go there, but I reckon not all that unexpected.

Please inform Wikipedia of their mistake(s).

Added the decadal trend line to the National Time Series chart – 1st one above. Comes in at +0.16F/decade.

Then I changed the date of the trend from 1895 to June 1936. The trend is +0.42F/decade.

Needless to say, that is long before any potential human footprint in global temperatures..
