grindupBaker at 09:34 AM on 28 July 20222nd law of thermodynamics contradicts greenhouse theory
Frankamungus @1512 One interpretation of your question is that you simply want to see a formula such as:
f = 5.35 * ln (CO2<now>/CO2<before>) w / m**2 for the heater of a CO2 increase in Earth's atmosphere from CO2<before> to CO2<now>.
If so, that's the one on NASA Web site and I've vague recollections of seeing assertions of values other than the 5.35 over the years.

Fixitsan,
In post 67 you say:
"I made it5 clear in my first response that I was aware of a difference between local and regional and global terminologies"
Then you refer to your claim that the sea level is not rising in the Maldives. We are not talking about a single location when we discuss sea level rise, we are talking about Global Sea level Rise. When you describe sea level rise at a single location and then claim that global sea level rise is not a problem it appears that you do not understand the difference between the Maldives and the entire world.
Fortunately Tamino has done an article on Global Sea level Rise (that is the average sea level rise for the entire globe, not just the Maldives).
We see that the global sea level rise is about 200 mm from 1900 to 2020. The current rate of Global sea level rise is 5 mm/yr. From year 0 (zero) to year 2000 we know that sea level rise was about zero siince Roman ports on the Med sea are still usable (as are major ports all around the world). If sea level rise was even 1 mm/yr that would have been 2 meters of sea level rise over a 2000 year period.
I look forward to your link to a site that shows current Global Sea level rise is comparable to the rise from 0 to 2000 CE.
I note that sea level rise is accelerating. According to Tamino, before 2010 the sea level rise rate was less than 4 mm/yr.
Where I live in Florida, Tamino shows that the current rate of sea level rise is 11 mm/yr. That is "scarily high". 21 million people live in Florida. Real estate in Florida near the ocean is increasing in value at a slower rate than inland since sunny day flooding is already a problem in most of the state near the ocean.

The comments in that Beer's Law post also provide a lot of relevant discussion, Frankamungus. I suggest that you post further questions on that thread, unless you have questions specifically related to the 2nd Law (this post).

Frankamungus:
For the basics, you can read about the Beer-Lambert Law (atmospheric absorption of IR radiation) on this page:
https://skepticalscience.com/from-email-bag-beer-lambert.html
Relating this absorption to increasing temperature is not the result of a single equation. It involves a system of equations relating the complete energy balance. Comment #15 on that blog post includes references to two early papers that do the math in one dimension (vertical).

Fixitsan @67 , your return to this forum will be most welcome, if you choose to come with some well-reasoned arguments. Arguments which are scientific and Forth-right, rather than merely rhetorical.
Meanwhile, may I commend for you the specialist blog: "WUWT". That blog hosts a large number of denizens who delight in all sorts of motivated reasoning and deficiencies in self-awareness. Quite entertaining, to see how the WattsUpWithThat-ites fail to grasp science and fail to look at the Elephant In The Room. Indeed, a very recent article by a Mr Kip is chock-full of uninsightful wordiness. . . . about numbers ;-)

I made it5 clear in my first response that I was aware of a difference between local and regional and global terminologies
I was accused of not being aware of those differences several times by what must be assumed to be people who had not read the first post I made on this topic.
Which, is pretty frustrating, and further frustration is felt by other posters then sayying I did not accept a difference in those terms when clearly I had.
Look at it from my point of view, it appears there is deliberate twisting and deliberate misunderstanding of what I wrote for what I assume are just personal humour reasons.
You might as well have just said "Stupid denier" and be done with it.
What is it about a lack of sea level rise which makes it so obectionable in a discussion about climate change ona climate change website to make moderaters call it off topic.
Until climate change came along sea level rise was just a normal fact of life, before it became something that has been given a new name as if it is a new phenomenon.
I leave to play your games, I'm more than capable of a broad discussion and tolerate a lot of topic deviation because that is what happens during the turn of conversation in real life.
You don't want to talk about a lack of sea level rise of a rate which is considered to be a worldwide threat, yet would allow to be published anything which claims sea level rise is not normal at all, and the current rate is scarily high compared to the past, when it isn't.

michael sweet @65,
To make plain the Moderator comment, @3 the record high night-time temperature of +25.8ºC is a HadUK value set 19/7/22. The +18.9ºC for 19/7/22 in HadCET was the second highest HadCET night-time temperature with the record +19.5ºC being set 20/7/16. And as this all suggests, there have been more recent record high night-time CET temperatures than have survived from earlier decades.

John Masons' post @3 shows that the all time high low at night was set during this heat wave. Everyone informed knows that nights are warming faster than days and that the warmth is statistically confirmed. Fixitsan is just making things up.
Fixitsan: provide a link that shows data that the low temperature at night is not increasing.
Moderator Response:[BL] Should Fixitsan wish to restore any credibility, he should provide such an analysis. Since his most recent claim (#59) references CET, he should focus on that.
For what it is worth, there are links in the comments to this blog post that will lead to the Met Office's daily CET data from 1878 to present.
Spoiler alert: the daily minimum temperature from 1878 to today results in a linear trend of 0.78C per century. If you look at just the last 50 years, it is over 2C per century.

plicoin24:
Air temperatures are strongly linked to ocean temperatures, so although they are more variable, they are useful. We also have air temperatures - especially over land - for much longer periods than we have good deep ocean data. As such, air temperature trends can be determined much further into the past than ocean temperatures.
Air temperatures are not "wrong", but it is correct to say that ocean data is better for global trends - if it is available. Climate science benefits from having both.

No curiosity embedded in you at all then ?
Maximum highs are rising
Maximum lows are not

The maximum highs might be hotter, but the maximum lows are not, adn there is no certainty that next year will be one of the maximum high year instead of a normal one

David-acct@2, as nigelj pointed out, the variation due to solar fluctuations is small. We are currently warming about 0.2C/decade. I think it is difficult for most people to realize just how rapid that really is. Nature gave us cycles which, for the most part, slowly vary, such as TSI. The anthropogenic warming is currently swamping all other natural warming/cooling cycles.

Let us not forget that when we look at the graphs for global average surface temperature of the Earth vs. time, we are in some sense looking at the wrong graph if we want to know if the world is warming up. The fact that more than 90 % of the heat energy that the Earth accrues do the climate forcing supplied by greenhouse gases means that the lower atmosphere is much more subject to fluctuations in average temperature than than the ocean.

Why does the CET show that all mean low temperatures are not recent ?
Surely warming would increase the average low temperatures too, or else we're only talking about increasing peak highs, which is not the same as a general warming trend
Moderator Response:[BL] You are literally arguing with yourself. First, you use the term "all" with reference to a local/regional example, and then you clam that this relates to some characteristic of "a general warming trend".
Your back and forth between local, regional, and global, and your repeated failure to be consistent in your interpretation, is turning your posts into incoherent rambling.

""you treat us to the bizarre idea that we should be able to use the house prices on the Maldives to measure AGW ""
No that is your own disingenuity regarding the economic certainty that if the Maldives were about to be abandioned then nobody would live there, the house prices would therefore be zero.
Is it actually true that you think an island on the brink of abandonment attracts serial investors and property sharks who pop up out of the water for no other purpose than tax avoidance ?
Are you in a place where houses which will soon be abandined have excellent values ?
We have lots of clifftop houses here which are worthless because they're about to fall into the sea due to longstanding coastal erosion, I just assumed nobody would be stupid enough to pretend to think a property on the brink of abandonment would hold any value in the proporty market, for the sake of trying to make a lousy point. But you did it !|
I don't know if you would pay for a worthless property or not now. perhaps you actually would !
But I think MOST investors, banks, economic deprtments of the Maldives, and even loan sharks would, quite sensibly steer people away from investing on things about to be washed into the sea.
Conclusion - the properties are safe, or the world has gone mad

"I wasn't talking about flat period of global temperatures mid last century, but instead a flat temperature in the UK from 1910 and proceding into the 1990s, which is 70% - 80% of the last century,...."
Ok, but I was just trying to make the point there are almost certainly logical explanations for that long flat period. So for example the first link I posted discussed how different regions warm at different rates, - and would also have different timing of the warming. I havent looked at mid Englands climate history and what factors have driven it, but there is bound to be some local or regional factor or combination of factors that explains the unusually long flat period of temperatures, despite rising CO2. And obviously a large part of that flat period is explained by sulphate aerosols (from about 1945 - 1980).
I agree quoting that particular temperature record could get you labelled a denier. Not sure what the solution to that is other than to say I don't personally dwell on very local temperature records like that, because its incredibly obvious that in our complex climate system there will be a lot of local variation. I'm mostly just interested in the global average trend and whats happening where I live myself. Local variation doesnt bother me because anyone with more than half a brain knows that doesn't represent the global trend and there are dozens of plausible reasons consistent with an anthropogenic warming trend.
And I agree the media sometimes exaggerate climate change. What can you do about that? I've complained to my local media for both exaggerating certain things, and and playing down other climate issues. It's the second problem thats a bit more concerning.

Changes in solar irradiance produce a much smaller warming effect than the anthropogenic greenhouse effect, so any solar heat energy thus sequestered in the oceans and later released, isn't going to be hugely significant. As follows:
"The Sun's overall brightness varies on timescales from minutes to millennia, and these changes are detectable in the global temperature record."
"During strong solar cycles, the Sun's total average brightness varies by up to 1 Watt per square meter; this variation affects global average temperature by 0.1 degrees Celsius or less. "
"Changes in the Sun's overall brightness since the pre-industrial period have been minimal, likely contributing no more than 0.01 degrees Celsius to the roughly 1 degree of warming that's occurred over the Industrial period."
"Projected warming due to increasing greenhouse gas levels in the coming decades will overpower even a very strong Grand Solar Minimum."
"Rising amounts of atmospheric carbon dioxide have postponed the next Milankovitch-driven ice age by at least tens of thousands of years."

Good point on the elevator graph. though it raises an interesting point coupled with the article a few weeks ago on the ocean time lag and the recent knowledge gained from the research associated with the ocean time lag and how it can take 20-40 years for the warming to manifest in the atmosphere.
Total solar irradiance has increased since the late 1800's, and remains higher today than it was in the late 1800's . Granted TSI has dropped somewhat since the mid 1900 (circa 1950/1960) yet still remains higher than the early 1900's .
Scientists are just now getting a better understanding of the ocean time lag effect. It merits additional research into how much of the warming over the last few decades relates to warming from tsi and the long delay in tsi effect manifesting in the atmospheric temps

One Planet Only Forever at 08:17 AM on 26 July 2022Taking the Temperature: a dispatch from the UK
Fixitsan @42 (and other comments),
Thank you for accepting that averaging larger amounts of data provides a clearer indication of long-term trends like the impacts of increasing CO2 levels. That understanding leads to awareness that the surface temperature impact of increased CO2 in the atmosphere is best seen by the trend of the global 30-year moving average (the global version of the one for CET presented on the Wikipedia page I linked to @40). Also, the 30-year ‘global average’ is understandably the better indication of the trend than any regional 30-year average.
I have more to share regarding CO2 and temperatures. But the following will hopefully help explain the comments I will make.
We appear to agreed that many people appear to be uninterested in putting the effort into pursuing the most logical explanations for the ever increasing evidence of what is going on. Learning requires a willingness to change your mind based on ‘new information and evidence’. It can require giving up on developed (status quo) beliefs and actions (no matter how popular, profitable or enjoyable they are).
The following 6 minute BBC Reel item “The psychology behind conspiracy theories” is informative. Watch it. Think about it. Then watch it again. Then seriously consider the possibility that you are resisting learning for some reason(s).
When there is a lot of evidence, as there is regarding climate science (especially since the first IPCC Report in 1990), the understanding still improves as additional evidence is obtained. But the fundamental understanding developed by 1990 is very unlikely to change ‘statistically significantly’ due to new evidence. And the observations you make regarding CET are not ‘new evidence’ (btw, Why is your focus on anything other than what the CET 30-year average trend since 1990 indicates?)
Many other comments have been helpful (they really are), but I will only refer to a few of them.
Bob Loblaw @47 provides a great overlay of the history of CO2 levels and global average surface temperature (GAST). But the 30-year moving average temperature line looks even more like the CO2 line.
You can use the SkS Temperature Trend Calculator to see the 30-year GAST trend for the GISS v4 (the temperature dataset Bob Loblaw used). Choose GISTEMPv4 and set the follow: Start date = 1880; End date = 2023; Moving average = 360 months (30 years). The GISTempv4 30-year moving average increases between 1920 and 1950, and after 1965 (note that there is no ‘levelling off’ in a 600-month moving average). What is happening in the CET is similar. But local conditions can be understood, and expected, to vary relative to the global trend. The term ‘vary’ leads to the next points.
Many variables affect the GAST. It isn’t just the CO2 levels. Increased CO2, primarily due to fossil fuel use, is known to be ‘the major factor’. However, additional variables affecting GAST are already well understood (with more being learned – because – well that’s science for you). They include:
- Aerosols (see nigelj @45)
- Other ghgs in the atmosphere, not just CO2
- ENSO (el Nino, la Nina)
- Solar radiation levels
- Milankovitch (Orbital) Cycles
In addition to variables affecting GAST, there are other factors affecting local climates including:
- ENSO (it affects regional climates as well as being large enough to affect the GAST)
- Atlantic meridional overturning circulation AMOC
The AMOC is weakening due to Global Warming. That could mean cooler winters in the CET region even with increased Global Warming due primarily to increased CO2, due primarily to human activity (primarily fossil fuel use).
So ... it is not wrong to say “Increased CO2 = increased GAST”. All that needs to be understood is that CO2 due to fossil fuel use is only the primary part of the 'increasing GAST and resulting Climate Change' problem.
Closing with a brief bit about the future of the Maldives due to increasing GAST. Reviewing the Climate Central Map of “Land projected to be below annual flood level in 2050” (a detail you missed or misunderstood when commenting about bridges near Edinburgh) you can see that only ‘most of the Maldives’ will be expected to be annually flooded by 2050 (using the default settings). More of the Maldives would be annually submerged in subsequent decades. Mind you, with the default settings, even by 2100 there are still little bits of the Maldives above the annual flood level. A related understanding is that people playing marketplace games can make 'very bad bets'.
A related understanding is that people playing marketplace games can make 'very bad bets', like investing in fossil fuelled pursuits, or buying in the Maldives (like the unfortunate people on Kona, the Big Island, Hawaii who chose to buy property and live in areas that are now under lava).

Fixitsan @42-44&46,
It seems SLR has gone Forth and we are now back amongst the sassenachs with their CET record.(Note you miss the point @43 where you respond to a caooment which is questioning why a discussion of CET should suddenly be discussing a strange article in the Edinburgh News abuot SLR projections.)
@42&44 you forget that it is the global average SAT which will show some warming from a positive climate forcing resulting from increased CO2, and react with lots of warming from a big positive climate forcing like the CO2 forcing within AGW.
But as you say up-thread (perhaps you have forgotten), the temperature record of a wider area provides a "better guide" than a smaller area. So @42 perhaps the question of what is causing these CET wobbles of the 1970s/80s (or any other period) may provide an exemplar for why a smaller area is more wobbly than a biggerer one. And @44 there appears to be some inane idea that global SAT (& thus also wobbly CET) should have been rising vigorously since that day Abraham Derby first thought to make his steel using coal rather than of charcoal.
@46 you treat us to the bizarre idea that we should be able to use the house prices on the Maldives to measure AGW (with some inverse correlation) and because there is no indication of any falling prices to be seen, "the average person" will thus conclude the political message on AGW is yet more nonsense from the political classes.
Yet in such a world, what "the average person" thinks or doesn't think makes no reference to the SLR records in the Maldives.

Oh, my. And while I was preparing comment #47, Fixitsan has posted #46, where again he fails to recognize that CET is not the UK, fails to realize that his eye-crometer view of trends is off (refer to the Tamino post I linked to earlier), repeats his grossly-inaccurate characterization that rising CO2 must cause constantly rising temperatures, fails again to actually look at when the CO2 rise is happening...
...and goes off on another tangent about sea level somewhere else in the world.

Bob Loblaw at 23:34 PM on 25 July 2022Taking the Temperature: a dispatch from the UK
...and Fixitsan is back to his bogus argument that rising CO2 must create temperatures that are "always undoubtedly more warming". Is Global warming still happening? is #5 on the list of most common myths. Does CO2 always correlate with temperature? is #47 on the list of most common myths.
And he's picked the cherry of the 1970s cooling. Why did climate cool in the mid-20th century? is #49 on the list of most common myths. Will he chase the squirrel of early 20th century temperatures next? That is #52 on the list of most common myths.
And he's justifying going off topic for this blog post ("Taking the temperature: A Dispatch from the UK") because he seems to be incapable of using the search function (top left of every page at Skeptical Science) to find a post where sea level rise is on topic. Oe perhaps he simply does not understand that the link between sea level rise and global temperatures is the result of the slow overall rise in global temperature, not the week of record-high temperatures in a small part of the world (the UK). Given his repeated failure to understand the global vs local relationships for temperature, it seems quite likely that he is equally-poorly-informed about the causes of sea level rise.
And he returns to the CET temperature trend as if local variabilty disproves global trends. (He's still wrong.) And he goes into the pre-1900 period (part of the "Industrial Revolution") as an example, seemingly unaware that CO2 rise is largely a 20th century phenomenon - and mostly the latter half of that century.
I need to correct an earlier misunderstanding on my part. Fixitsan is not playing "look, squirrel!". He's playing Climate Myth Bingo. Which square will he call out next?

I wasn't talking about flat period of global temperatures mid last century, but instead a flat temperature in the UK from 1910 and proceding into the 1990s, which is 70% - 80% of the last century,which is a period of time I bet if you asked the layperson to describe in terms of temperature for that period almost certainly would argue that because CO2 has risen for that century then so too must have temperature. To even suggest to them that that had not been the case, even backed up by such a reliable and noteworthy source, is just bound to have you labelled a denier, despite being backed up by science in that case. Well, if it isn't the layperson who would say that, any of the 'journalist fact repeaters' and news cockatoos would definitely stick their oar in.
To even get to that stage though suggests there is an enormous disconnect between what most people think and what is happening in reality. Science provides the data for reality and I assume the media in general make it their mission to sex up everything to do with climate change out of habit.
I still wait every morning for the final calamatous news that the Maldives have finally become a victim to sea level rise, as I was assured by the Maldivian climate minister and international scientists should have happened by today that it was the only certain outcome if CO2 production did not decline. CO2 output has increased over those 30 years .
Concerned about the properties of the people there I turn to Google and type 'Maldivian Properties risk' and get nothing but pages and pages of property sales pages reporting increasing property prices due to a high demand in the The Maldives, representing a good risk for investment. How interesting it is to find presumably otherwise finance savvy investors throwing money out to be washed away with the at risk properties in the Maldives (sarc)
You would think for an island constantly on the cusp of being destroyed it ought to be seeing falling property prices !
The cost of living in The Maldives is 9.82% lower than in the UK
Rent in The Maldives is 11.3% lower than in the UK on average
Surprisingly expensive for somewhere about to disappear forever under water that will rise and engulf it, apparently, when it gets around to it, it's just busy not rising all that quickly at the moment and has not been for quite some time indeed.
So did the Maldivian Environment minister and international scientists lie ? Perhaps they only made the most dire prediction possible and that hasn't come true. But in itself that makes it difficult to detect when any other prediction is a realistic one or if that's also the most dire possible prediction. Under these circumstances who can blame the average person for feeling like it is just business as usual where politicians are concerned, always amplifying negatives and generating high levels of irrational fear, but conveniently always leaving office before they have to be held accountable for being wrong. Again. Business as usual.

The reason different parts of the world warm at different rates is discussed here.
The reason there was a flat period of global temperatures mid last century in the centre of England and for the planet as a whole was because industrial sulphate aerosols suppressed the warming caused by CO2. This effect ended around the 1980's as CO2 concentrations became large enough to overcome the effects of aerosols, and the quantities of aerosols dinished as coal fired power stations fitted equipment to filter much of them out. I believe this was to reduce acid rain effects and their affects on respiration.
This material is mostly intuitively obvious and takes only seconds to find on the internet. Why people can't find it is beyond me.

Regarding the CET it seems to show no net gain in temeprature between about 1760 and 1910. An amazing sight to see, shoudl I be ever tempted to read news headlines which assert that temperatures have been rising continuously throughtout the industrial revolution. Not in Central England, they haven't.
Of course it depends if you use the 10 year or 30 year average but short term trending allows more noise through but regardless of that, warming only seemed to being in 1910 on the CET terecord, reached temperatures as high as those seen in 1730 by about 1940 (it remained colder than 1730 until 1940) and since 1940 we have seen a discontinuous warming, which incudes a cooling starting in the 1960's which doesn't finish cooling until the 1990's
With a lack of variability in atmospheric CO2 levels over that 100 or so year period (the change in CO2 has been steady and predictable, rarely variable) being coincident with the CET record during that time, it's visible to see that the theory of more CO2 = more warming is not being measured by instrumentation in the last 100 or so years. That is not to say that CO2 does not cause warming, but the CET record doesn't show what I believe many epople might understand is happening in their own minds when picturing the promoted relationship between CO2 and temperature on it's own

@ Bob ""I'm not sure exactly what sea level rise has to do with temperature records""
No, perhaps reading any press article which consistently ties the two together ought to be all you need to do to raise your awareness.
Say 'climate change' on any high street, hear ' sea level rise' addended
Perhaps though you weren't aware of any previous connection between temperature and sea level ? Have you heard of a thing called climate change thepory ? Perhaps ? Maybe ? Oh well, hideaway.

One Planet, with reference to your own referenced series extracted from CET
Why was there a cooling starting at around 1972, with temperatures not recovering tot heir pre 1970's level until the 1990's if CO2, the alleged cause of all warming, was rising throughout the same period ?
The theory is more CO2 = always undoubtedly more warming.

One more (last) poke at how hard it is to misunderstand what the HadCET dataset shows:
- The following webpage "Met Office Hadley Centre observations datasets: HadCET", is the page linking to downloads of the dataset. The dominant feature on that page is a graphic presentation of each year's 'Mean Temperature difference from 1961-1990 average'. What it shows is hard to misunderstand.
- The Wikipedia page for Central England Temperature has a section called "Trends revealed by the series" includes a graph of the 10-year and 30-year moving averages. That shows that prior to 1950 there was only a brief period (around 1735) when the 30-year average was close to being as warm as the coolest values since 1950. And since 1990 the 30-year average has consistently 'statistically significantly' increased. It also shows that the current 10-year averages are warmer than any 10-year averages before 1990. And it also shows that the annual data points cover a broader range than the 10-year average, which has a broader range of values than the 30-year average. That should lead to understanding that the monthly values would have a larger range than annual values, with daily values having an even larger range of values.

Fixitsan says: "We are definitely only talking about a single location on the planet which continually monitors the temperature, unlilke [sic] most locations on the planet."
If the implication is that the region covered by CET is a single location on the planet which continually monitors the temperature, unlike most locations on the planet (the problematic part of the point), then we are not talking about the same thing, or at least 'we' have not yet developed a shared common sense of the bigger picture (reasonable common awareness and logical common understanding based on all of the evidence).
Where I live in Canada, scientifically collected (with Stevenson screens and all the other protocols) temperature data is available back to 1884 (when the region I live in was being harmfully over-taken in a 'settlement way' by the invading European colonizers - another emerging understanding that misleading marketing has held at bay for centuries). I am sure there are many other locations with longer histories of temperature data than the region I live in, not just CET.
Check out my comment on the Skeptical Science New Research for Week #29 2022.
There are many unreasonable reasons for the difficulty in establishing a common sense understanding regarding many issues these days. The power of misleading marketing is probably the most damaging scientific development by humans, likely more damaging than nuclear weapons or the diversity of fossil fuel developments.

Bob Loblaw at 03:57 AM on 24 July 2022Taking the Temperature: a dispatch from the UK
Wow. Fixitsan sure has a wild game of "look, squirrel!" going on.
From an original claim that a long list of temperaure records from the Central England Temperature series represented UK "national" values, he's gone into full retreat. No longer calling it "national" (he must have run out of "national"s in his keyboard, having used it nine times in his first post), he's backed down to calling it "regional" (not unreasonable), and then local, and finally (in comment #24) saying "We are definitely only talking about a single location on the planet which continually monitors the temperature, unlike most locations on the planet."
His game-killer statement? "But there is clearly 1 location on the earth where that is not true." (He's talking about places with record highs.)
Now, if he had looked at (and understood) the figures provided in the article, he would see that the rise in temperatures across the globe is not uniform. Here is the original figure, copied again:
Notice how the maps show a range of colours? The dark red ones are the hottest (relative to their normal temperature), and the blue ones represent locations that were colder than normal, with a range of colours in between. And Fixitsan seems to think that this is news - and devastating to the science of climate change. Of course, it is not. It's just a variation on the myth "It's freaking cold!" that Skeptical Science already has a page on.
If he understood anything about weather, he would also know that "climate" includes variations about the averages. Gradual warming does not mean that we'll never see cold again (see above link about "it's freaking cold!"), and it also does not mean that we'll never see record cold temperatures set. What we do see is records highs being set a lot more frequently than record lows - as would be expected in a warming climate. It turns out that Skeptical Science has a post about that, too.
https://skepticalscience.com/Record-high-temperatures-versus-record-lows.html
So, Fixitsan still hasn't said anything that is actually new, or that goes against our understanding of climate and climate change. He's just repeating myths that have been around for years - and debunked many times.
His closing comments on temperature seem to be: "...the question needs to be asked about how many other areas do not align with the global trends, and therefore apparently challenge the notion that global warming is not global (affecting everywhere) at all."
Guess what? Some areas are warming less than (or more than) other areas, and some may even show some cooling, but none of this represents any challenge to climate science. In fact, observations such as increased warming at the poles, regional variations in warming, etc. are all things that were predicted by climate theory. Fixitsan's "show stoppers" are actually confirmation of the science.
Then, running out of myths to retreat to on temperature, Fixitsan has jumped the shark to start going on about sea level rise. He's not doing any better on this. All he seems to have is some newpaper headlines and misinterpretations of same.
I'm not sure exactly what sea level rise has to do with temperature records, but I guess the discussion is a least on topic with the UK slant of the blog post.
Having seen his sea level "gotchas" torn to shreds, will we see Fixitsan jump to chase another squirrel? There are lots to choose from. Check out Skeptical Science's Most Used Climate Myths, choose your favorites, and place your bets!

MA Rodger at 03:05 AM on 24 July 2022Taking the Temperature: a dispatch from the UK
Fixitsan @33,
So, are you sitting comfortably? Then I'll begin.
The Edinburgh News may appear distributed nationally across Scotland if you live in Edinburgh, but elsewhere it is absent from the shop shelves although it maybe they keep it below the counter for the conveneince of Lothian folk.
The new bridge at Kincardine has been called the Clackmananshire Bridge since 2008 (previously the Upper Forth Crossing) and it is named as such by the original article in the Scotsman. Mind, you folk down-river may have a different name for it.
But as pointed out @ 26, whatever it is called and whether or not it has "a high water clearance of 9m to the underside of the deck" is all rather irrelevant as it is a hump-hacked bridge (although a very long one) with its approach roads (as with the old Kincardine Bridge) built across the flat lands alongside the water. So with a bit of SLR you maybe can cross the bridge dry-foot but you'd need a boat to access the bridge. This was presumably what the original copywriter at the Scotsman was saying when he tapped out "areas near the Clackmannshire Bridge were identified as at risk" while his editor and some credulous Edinburgh hack then added in the ridicule which you are attempting to prolong.

One Planet Only Forever at 02:30 AM on 24 July 2022Taking the Temperature: a dispatch from the UK
Fixitsan,
Regarding the Scotsman article about things near Edinburgh likely being ‘below annual flood levels in 2050’ have a look at the Climate Central map that is linked in the article:
“A map produced by Climate Central, an independent organisation of leading scientists, shows the most under-threat areas.
The map predicts the impact climate change would have by 2050.”
The presented description of the actual Climate Central map is “Land projected to be below annual flood level in 2050”.
Indeed, the approach roads to the Kincardine Bridge and Clackmannanshire Bridge (not the tops of the bridges) are indicated to be below the likely annual flood level in 2050. The approaches to the A91 bridge over the Forth would also be below the likely annual flood level in 2050. And the approaches, and significantly more road length, to the M9 and A905 crossings of the River Carron are also below the likely 2050 annual flood level.
That leads to understanding an answer to your question in your comment @24: "What is one to say to someone who shows to me that the hottest May was nearly 200 years ago ?"
The problem appears to be a lack of interest in more fully, and more logically, investigating things, even things that are rather easy to more logically fully investigate and better understand.

One Planet Only Forever at 02:04 AM on 24 July 2022Skeptical Science New Research for Week #29 2022
The following BBC News item is research related.
The audacious PR plot that seeded doubt about climate change
The opening of the investigative reporting story is:
"On an early autumn day in 1992, E Bruce Harrison, a man widely acknowledged as the father of environmental PR, stood up in a room full of business leaders and delivered a pitch like no other.
At stake was a contract worth half a million dollars a year - about £850,000 in today's money. The prospective client, the Global Climate Coalition (GCC) - which represented the oil, coal, auto, utilities, steel, and rail industries - was looking for a communications partner to change the narrative on climate change."
And a concise summary point in the investigative reporting story is:
"What the geniuses of the PR firms who work for these big fossil fuel companies know is that truth has nothing to do with who wins the argument. If you say something enough times, people will begin to believe it."
And people are more likely to believe a misleading/deceptive claims if they have developed a desire to benefit from believing the claim, no matter how harmfully incorrect their desire can be shown to be.
More telling is that it appears that many 'whistle-blowers' are only now speaking up, decades after the beginning of the disastrous damaging plot they worked on as secretively as possible (and after Harrison died in 2021). Many other people have already broken through the attempts by the nasty deceivers and cheaters to hide what they are doing or find other ways to get away with understandably harmful actions.
There have already been other evidence-based reports, notable is Merchants of Doubt (the 2010 book by Naomi Oreskes and Erik M. Conway), on the sordid and wicked things done in the grand massively damaging deception schemes that some very wealthy powerful people and a bunch of greedy others undeniably pursued (and continue to try to get away with).

It is, and I found it quickly long before you posted the link by a simple search - but it did not get widely-circulated in the denialosphere, probably because it's so self-evidently ridiculous. That means even they didn't think they could get away with using it to attempt to undermine climate science - always their prime objective. Was probably the work of an intern with about 3 days of experience!

MA Rodger, clearly not a local, the bridge in Clackmananshire is the Kincardine Bridge, known by no other name.
The Forth Bridge pertains to either the Forth Rail Bridge or Forth Road Bridge, either way, well over 50m or more above sea level.
The Edinburgh News is distributed nationally in Scotland, with the Herald and the Scotsman.
But just for the sake of pedantry as you[ve opened that gate, the Kincardine Bridge (The old one or the new one, you did not specify ?) has a high water clearance of 9m to the underside of the deck.
9m/28 years = 321mm per year of sea level required. Looking forward to hearing you explain how that is possible, when the highest ever during the meltwater period was approximately 60mm per year.
Nearly 1mm PER DAY
You're deluded if you think it is possible, but I cannot wait to hear you explain , how ?
