:staregonk:  Imagine how awful it must have been during the Holocene Optima  or the Minoan, Roman and Medieval warm periods!  Oh wait - it wasn't.

Imagine how all of those warm periods were driven by the devil gas carbon dioxide.  Oh wait - they weren't.

Wake the fuck up.

Science / Re: NH winter cooling
Meanwhile, back in reality land
Tell me it's not true, FX!

Gulf Stream current at its weakest in 1,600 years, studies show

Wtf do you mean by "true" here?  The junk media article you reference is attempting to be alarmist about a study which is yet another CMIP5 GCM effort.  So if you want to believe that the output from a model ensemble with zero demonstrated predictive skill in a coupled nonlinear dynamical system may be ascribed the value "true" then that's your problem.

"This weakening is revealed by a characteristic spatial and seasonal sea-surface temperature 'fingerprint'--consisting of a pattern of cooling in the subpolar Atlantic Ocean and warming in the Gulf Stream region--and is calibrated through an ensemble of model simulations from the CMIP5 project".

Meanwhile all of the actual measured data gathered over recent years clearly indicates that AMOC is doing anything but slowing down.

This weakening AMOC trope is one of the many alarmist zombie 'facts' and they cannot ever let it go.  When the data flatly refutes it then as usual they go with a model which says whatever they want it to say and that is what the compliant media report.  Twice today I heard worried groups of people talking about the Gulf Stream shutting down because it's all over one of the most extreme propaganda falsehood machines in the world known as the BBC.

The junk media typified by the Guardian tirelessly seek out junk science typified by climate modelling in order to support their endless alarmist narrative and will go nowhere near actual empirical data which falsifies it.

Science / Re: NH winter cooling
If the Gulf Stream collapses that will entail adverse consequences for me so notwithstanding it's the Grauniad let us have a look.

Quote
The first study found significant Amoc weakening after the end of the little ice age in about 1850, the result of natural climate variability, with further weakening caused later by global warming.

Quote
The second study suggests most of the weakening came later, and can be squarely blamed on the burning of fossil fuels

Quote
However, it is already clear that human-caused climate change will continue to slow Amoc, with potentially severe consequences. "If we do not rapidly stop global warming, we must expect a further long-term slowdown of the Atlantic overturning," said Alexander Robinson, at the University of Madrid, and one of the team that conducted the second study. He warned: "We are only beginning to understand the consequences of this unprecedented process - but they might be disruptive."

So we have a bunch of assertions to the effect that an observed AMOC weakening is caused by fossil fuel use.  Now you know by now what I'm going to ask for don't you.  The article also states

Quote
He [Dr. David Thornally] said current climate models do not replicate the observed slowdown, suggesting that Amoc is less stable that thought.

and

Quote
The [current] climate models don't predict [an Amoc shutdown] is going to happen in the future - the problem is how certain are we it is not going to happen? It is one of these tipping points that is relatively low probability, but high impact.

The models fail to predict it - in a truly shock result - so it apparently lies outside of what anthropogenic-driven climate science thinks it understands.  What then is the evidence in support of the assertion that this reported AMOC excursion is driven by human fossil fuel use?

Evolution of the system is about tipping points. It's not telling people weather reports, it's looking at feedback loops that affect attractor basins. i.e. stable patterns we associate with climate in this case.

You're preaching to the wrong choir.  I have a deal of sympathy for your position here but it's the modelers you need to be berating.

Those models are concerned with boundary conditions and state flip.

Ah, no, the model used in the OP paper is a General Circulation Model (GCM).

Modelling the impact of a Southern Ocean freshwater pulse
Our simulations used the Commonwealth Scientific and Industrial Research Organisation Mark version 3L (CSIRO Mk3L) climate system model version 1.2, comprising fully interactive ocean, atmosphere, land and sea ice sub-models22, 63, 64. CSIRO Mk3L employs a reduced horizontal resolution and is designed for millennial-scale climate simulations. The ocean model is a 'rigid lid' model (i.e., the surface is fixed), with a horizontal resolution of 1.6˚ latitude × 2.8˚ longitude and 21 vertical levels, while the atmosphere model has a horizontal resolution of 3.2˚ latitude × 5.6˚ longitude and 18 vertical levels. A smoothed version of the 2-Minute Gridded Global Relief Data (ETOPO2v2) topography (https://www.ngdc.noaa.gov/mgg/global/etopo2.html) was used for the simulations (Supplementary Fig. 7). Despite the reduced horizontal resolution, the model has a stable and realistic control climatology and has demonstrated utility for simulating the past, present and future evolution of the climate system63,64,65.

This particular GCM is described here https://eprints.utas.edu.au/2278/3/03CHAPTE.PDF

Quote
The development of Mk3L from these components is described in detail by Phipps (2006). The resulting model is computationally efficient, portable across a wide range of computer architectures, and suitable for studying climate variability and change on millennial timescales.

And

Quote
The model physics is described in Section 2.2,

And while revealing this to be a very impressive beast of a GCM, nowhere is there any mention of attractor basins or state flips.  These models operate by solving the relevant equations - or what are taken to be the relevant equations - across grid boundaries using finite element and/or finite difference techniques.  It's a brute computational force solution.

At least, that's what it means to predict the evolution of a dynamic system. You can't predict future points even on a Lorenz attractor, let alone an open dynamic system. That's a different kind of predictive value.

I also have deep reservations about the likelihood of success of this kind of modelling effort given the nature of the coupled dynamical system under consideration.

Here we see a cameo of everything that has gone so horribly wrong with climate science.  Now we codify a model in a deeply non-linear system with ill-understood or unknown feedbacks, don't demonstrate any predictive skill yet claim it has some relevance. 

The model used in this paper was not created to make predictions or forecasts,

The whole fucking paper is a modeled prediction starting from the last glacial melt water pulse you halfwit.  Now I understand Lamian's old sig.  You are a truly implacable waste of groceries.

Also, when your timescales are decades and centuries... well...
This is where Hari Seldon's model broke down!


And that is really about where we are with climate modelling.  It's pure science fiction yet is for some bizarre reason completely isolated from the normal strictures of science.
10
you can't predict a nonlinear system.

Yes you can.  If you understand the nonlinearities.  The acid test of course is can you make reliable predictions over more than a few timesteps.  It's a testing thing you know.  If people think they can for a coupled nonlinear system like the climate then they should make the predictions and let's see.  I know it's a bit backwards to express scepticism when people say they can predict the future but just indulge me anyway.
11
Yes indeed.  We humanzee throwbacks have that wild primitive hypothesis testing notion even now in the brave new modelworld.  We subscribe to the embarrassingly archaic view that hypotheses should reliably predict things.
12
Here we see a cameo of everything that has gone so horribly wrong with climate science.
I disagree.  They are trying to figure out why things happened as they did, in the past.  The deep ocean conveyor is a very important thing to understand.

I've no problem whatsoever with people trying to get a handle on things using numerical simulations.  The problem is that modern climate science goes on from there to treat the output of what are at best sketchy speculation as some sort of actual result.  None of it is any kind of a result until it progresses to the level of highly significant predictive skill.

Additionally whenever you see the word 'ensemble' with respect to climate modelling you know that you are dealing with zero predictive skill and this is the fudge to cover for that dismal fact.  Either you have a model which makes accurate predictions or you don't.  Having ensembles covering all conceivable system behaviours and using post hoc weightings which track the actual as-measured climate is becoming the new norm and obviously enough will never be wrong in the present but will likely never predict a thing correctly - but that doesn't matter because you simply adjust accordingly using your real world data-modified ensemble weightings in the future.
13
No one said that.  It's a typically stupid straw man.  The global temperature mean - whatever physical meaning you may wish to ascribe to taking an average temperature of the entire planetary fluid systems using thermometry - is quite possibly increasing.  I'd expect it is following the LIA.  I'd certainly hope it is because if it isn't that likely spells a return to a new local minimum which isn't good news at all.  In other news there are areas which appear not to be following the generalised trend and running counter to the predictions of the AGW hypothesis  The primary point is that when a record gets adjusted on a rolling permanent basis then it isn't a record at all.  It is a reflection of certain hypotheses advanced by those doing the adjusting.  The secondary point is that if you wish to ascribe the putative temperature rise to some causative agent then you need to provide the evidence to support those claims.  And the tertiary point is of course that NH winter cooling would be evidence refuting the AGW hypothesis.

Forecasts can generally predict how much precipitation an area may have several months in advance, but when it comes to specifically predicting snowfall, we're more in the dark. However, a new model may offer more advanced warning when it comes to the white stuff.

The current crop of alarmists just doesn't care to know.

Science / Re: NH winter cooling
I'm unclear that there are many "facts" established.

The only facts under discussion currently are related to what the prevailing scientific position was on temperature trends of the 1970's and I provided those facts above.

Quote
Aren't there a variety of estimates, projections as to what the climate changes may be in the future, if any?  But since projections may not include some complex or not understood interactive climate effects, we really just have to wait and watch for the facts to emerge.

That is my view yes and I'm a very long way from being alone in that.

Quote
I think we can take it as fact that our industrial activities are increasing the atmospheric C02 content at a significant rate as far as the numbers go.  But what does it mean?  My main take-away from scientific concerns dated to 1980 was that we were in effect running an experiment on our own nest.  Outcome uncertain, could involve undesirable climate changes, and if industry and population continued their growth patterns, and we make no efforts to curb carbon emissions, we will not be able to roll conditions back if we end up with bad climate results.

If there were evidence supporting the view that small changes in percentage composition of an atmospheric trace compound which underpins multicellular life and which is currently as low as it has ever been over the entire Phanerozoic is going to adversely impact the climate then these discussions would not be happening.  I for one certainly don't wish for the World to end and Big Coal are way overdue in paying me to say these things.

Quote
Maybe we will get lucky and it will eventually become clear that atmospheric C02 content is not much of a driver.  If we are not so lucky, there isn't much we can do about it at such a later date.

There isn't much we can do about it now - short of declaring nuclear war on India, China and the rest of the developing world because they aren't going to stop using hydrocarbons.  In addition you may like to have a look at projections of what effect we might in reality levy on global temperatures were we all to immediately and completely stop using hydrocarbons today?  Even if you accept that carbon dioxide drives temperature against all the available evidence and go with projections from absolutely worst case alarmist scenarios in which all of their so far unevidenced positive feedbacks turn out to be true.  You will probably be surprised.

Science / Re: NH winter cooling
Continuation.

Here's where Stewart and Glanz refer to actual scientific literature, although not any specific research:
Quote
Fueling the new-found political interest in climate was the debate that was then raging
in journals, meetings, conferences, and ultimately in the popular press about whether the
global climate was changing. Was it becoming warmer (with the appearance of book titles
like Hothouse Earth) or were we moving toward an Ice Age (with book titles like The
Cooling)? Still others, seeing the issue surrounded by a high degree of scientific uncertainty,
suggested strategies to cope with climate variability and change regardless of direction
(e.g., The Genesis Strategy: Climate and Global Survival). Selective evidence to support
each of these contending views could be found in the scientific literature
(e.g., it was
'time' for a new ice age, or thermal pollution or increased C02 loading of the atmosphere
would ultimately lead to a global warming).

So, the only remark they make about the scientific literature of the time, is that one could find support for either a warming climate or a cooling climate, if one was selective. Do you know what selective means? It's what you're doing.

Yes indeed selective evidence could be found for warming and cooling - just as it can today.  Unlike today though you probably wouldn't be sacked, vilified, slandered, have all manner of hysterical ad homs screamed at you, have your personal life attacked and threatened with court action for not going with the officially sanctioned selective evidence.  However the prevailing view of climate scientists at that time was cooling which - again - is why Stewart and Glantz conclude

Quote
One could effectively argue that in the early 1970s the prevailing view was that the earth was moving toward a new ice age.

And why the Subcommittee On The Environment And The Atmosphere Of The Committee On Science And Technology state several times that the prevailing view was cooling.  And that is supported by the overwhelming press reports of the day relating to the 'New Ice Age'.

So no, I'm not being 'selective'.  I'm referencing what was reported in what I consider to be reputable sources of the time.  You on the other hand are simply inventing your own unevidenced narrative that there was an equal division of scientific opinion between cooling and warming scenarios.

We have effectively the same conditions as prevailed in 1963 which triggered the great 'New Ice Age' scare of the seventies.

Yep. We still have the Yellow Press. There were a handful of researchers who made headlines with claims like these, but it did not hold up to scrutiny. The press forgot to report that the Ice Age scare turned out to be not real.

Lol your historical revisionist desperation is palpable.  So then if what you say is true and this paper from Stewart and Glantz along with its references may be construed as equally warming/cooling, why then were there countless press articles about cooling only?  Doesn't that strike you as at all strange?  Virtually none of them were talking about warming as far as I can find.  Here's a small sample from the English speaking press around the globe.

I feel reasonably confident the Spanish, French and German press were saying much the same.

The press don't simply make it up.  They take their lead from the prevalent opinions of the scientists of the day.  They of course ham it up but they don't simply pull it out of thin air.  Today virtually all of the press reports are about catastrophic warming because that is what the climate science community is feeding them.  There are plenty of scientists writing papers which do not support the catastrophic warming conclusion but the prevailing view of this time is for anthropogenic warming so that is what the press report.  The press of 1970's did exactly the same.  There wasn't an even balance of warming and cooling articles.  It was virtually all cooling and that is because that is what the climate science community were feeding them.  And that is why the major survey works of the day, commissioned to facilitate effective policy making, also concluded that cooling was the prevalent scientific opinion and also why Stewart and Glantz made the same conclusion from the perspective of the early 1980's.

The behaviour you exhibit here is primarily why I come to these threads.  The irrefutable evidence is all there in black and white and yet cultists will go to quite extraordinary lengths to deny it.  It shouldn't really be all that much of a big deal.  There was a period of cooling and people reported on it so what is all the fuss about?  The fuss is about the fact that this small and seemingly innocuous piece of information slightly undermines the quasi-religious never-to-be-questioned conviction of today's anthropogenic warming consensus and what is the cause of observed warming.  You haven't the smallest interest in what happened back in the seventies.  Your sole aim is to desperately defend your religion at all costs - and that interests me.

Science / Re: NH winter cooling
Continuation.

The statement "One could effectively argue that in the early 1970s the prevailing view was that the earth was moving toward a new ice age" is not referring to scientists, or climate scientists. It refers to policymakers and planners in government and the agriculture industry, the intelligence community and the general public. It most definitely does not refer to the prevailing scientific view.

This is a high level document and is indeed concerned with policy making.  Now where do you think "policymakers and planners in government and the agriculture industry, the intelligence community and the general public" get their information on the climate from?  Have a little think about that.  Do you suppose they all pull it out of their collective colon?  Or do you suppose it comes from the climate science community?

Read the selected reference list.

Bear in mind that this is a selected bibliography to give an overall impression of what kind of sources the authors drew from.  They looked at pretty much everything.  The climate literature,  relevant books, reports and publications.  People who compile these kind of surveys tend to be quite thorough.

Science / Re: NH winter cooling
Continuation owing to exceeded word limit.

There's no reference to any research into global cooling or ice ages, and no reference to any research about warming, either.  But that's ok, because this paper is not a review of scientific literature of that time.

The strange thing is that you appear to believe that this work  by Stewart and Glantz - on the subject of forecasting climate as it relates to policy making - was commissioned in a vacuum of reference to the actual climate of the day.  What would make you think that Stewart and Glantz felt enabled to make comments like


http://www.albany.edu/cpr/stewart/Papers/J1290-StewartGlantzNDU1985cap.pdf

Quote
The conclusions of the NDU study might have been predicted from a knowledge of the prevailing 'spirit of the times' (i.e., the prevailing mood in the science community) when the first part was conducted. This was an interesting time in recent history of climate studies. One could effectively argue that in the early 1970s the prevailing view was that the earth was moving toward a new ice age. Many articles appeared in the scientific literature as well as in the popular press speculating about the impact on agriculture of a 1-2°C cooling. By the late 1970s that prevailing view had seemingly shifted 180 degrees to the belief that the earth's atmosphere was being warmed as a result of an increasing CO2 loading of the atmosphere.  ... The causes of global climate change remain in dispute.  Existing theories of climate, atmospheric models, and actuarial experience are inadequate to meet the needs of policymakers for information about future climate.

without reviewing the literature of the day?  That would be just nuts wouldn't it.

Look at the table of contents of the document being referenced by Stewart and Glantz.  The online digitized version can be sketchy to read in some browsers so I'll roughly reproduce it here.

This paper analyzes the methodological underpinnings of a study of future climate

was designed to elicit expert opinion about the probability of different climate futures.
Its conclusions suggested that climate in the next twenty years would be similar to that of
the recent past.

Yes thanks I do.

The authors aren't arguing for anything.  They are reviewing the literature of that time and based on that review they conclude...

I seriously doubt it.  I've no doubt you skimmed the titles for what you desperately wish to believe.

Were you aware that Stewart and Glanz did not include in their references even one citation to research about climate change?

Were you aware that many of those references are to massive tomes of work already completed which cite the literature?  Try actually reading the references instead of assuming what you think they say.  For example the third reference is to a 416 page document 'A Primer On Climatic Variation And Change Prepared For The Subcommittee On The Environment And The Atmosphere Of The Committee On Science And Technology U.S. House Of Representatives Ninety-Fourth Congress'.

PERSPECTIVE A growing fraction of current evidence suggests that the world may be entering a new climate regime. Amid recent expressions of concern that the Earth may be on the verge of entering a new ice age, a potential serious problem for mankind is perceived. However, this concern has been voiced by many, both within scientific circles, and through the mass media without the qualifications appropriate to any such venture into the realm of the predictability of climate.

Impact of Climatic Change If present global cooling trends continue for several more decades, high latitude areas such as Canada, the U.S.S.R. and northern China would experience shorter growing seasons and a drop in output. Helmut Landsberg, a climatologist at the University of Maryland, estimates that a drop in average temperature of 2 degrees centigrade in the region above "ij The degree month value is the sum of the mean monthly temperatures in excess of 32 degrees Fahrenheit. CRS -14 the 40 degree parallel would completely eliminate wheat and corn production in major regions of Canada. A decrease of 1 degree Centigrade in the mean annual temperature in Iceland has already reduced the number of degree days by 2 7 percent --a reduction in the growing season of 2 weeks. In addition to shorter growing seasons from a cooling trend, there would be broad bands of excess and deficit rainfall in the middle latitudes. Europe can expect to be cooler and wetter. The western regions of the U.S. wheat belt- -from Montana to Colorado --would experience increased wheat crop failures. The northern Great Plains would experience a 14-18 day reduction in growing season, but the southern plains would gain in crop yields due to increased rainfall. In general the existing crop belts of the U.S. would shift southward. Overall U.S. agricultural production would be unaffected or perhaps slightly increased. The monsoon rain belt would also shift southward causing these rains to fall into the oceans rather than the traditionally fertile areas of sub- saharan Afri«ca, India, Japan and south China. Production of rice would be seriously affected in the warm lands below 30 degree latitude. Impacts on Agricultural Trade Climatic changes of the order just described would drastically affect the capability of nations to feed their people and the availability of food from traditional exporting nations. In Europe the number of persons supported per hectare of land would fall from 3 to 2; in China from 7 to 4 according

Although it is almost unanimously held that the Earth is presently in a phase of climatic change, theories as to the future course and rate of the change vary considerably. Today, most experts agree that the Earth is in a cooling phase. Proceeding from that observation, the following scenarios for the future are commonly predicted: 1) that Earth is slowly (ever thousands of years) entering into a new ice age; 2) that Earth will rapidly (within 100 years or slighly more) enter in- to a new ice age wherein much the planet will be locked in glaciers; 3) that the present cooling trend is only a minor aberration due to cyclic sunspot activity and is not necessarily a harbinger of a new ice age; 4) that man's activities (release of CO2, heat, and other substances into the world's weather machinery) will forestall the onset of a scheduled ice age; and 5) that man's activities will accelerate the ice age process

They also say

However, there are also some experts who hold that, contrary to the above, the earth is in a long-term warming phase. Proceeding from that theory, the following scenarios for the future are commonly predicted: 1) that the Earth is slowly (over thousands of years) emerging from the last ice age; 2) that presently, more areas of the world are warming than are cooling; 3) that cooling over the past three decades is but a minor regression in a longer-term warming phase; 4) that man's activities will precipitate either a slow or fast warming process; and 5) that so significant is man's impact on the weather, that a major warming trend will soon melt the ice caps triggering a global increase in sea level.

Although the most popular theory appears to support a global cooling trend, it is almost unanimously agreed by most experts that any climatic o change, even one resulting in a change of as little as + 1 C will have a profound effect on global human health and welfare.

By far the most popular theory today is that the Earth is undergoing a cooling trend. Just how rapid this trend will be, and therefore, what its impact will be on man is the subject of much speculation. In any event it is widely held that the world climate was unusually stable be- tween 1890 and 1945, but that since 1950, began taking a turn for the worse.

According to Professor Hubert H. Lamb of the Climatic Research Unit in Great Britain, "The decline of prevailing temperatures since about 1945 appears to be the longest continued downward trend since temperature records began, " 12 /

It's a review paper.  Do you understand what that means?  The authors aren't arguing for anything.  They are reviewing the literature of that time and based on that review they conclude

This was an interesting time in recent history of climate studies.  One could effectively argue that in the early 1970s the prevailing view was that the earth was moving toward a new ice age.

and that

Many articles appeared in the scientific literature as well as in the popular press speculating about the impact on agriculture of a 1-2°C cooling.

If you don't like it do your own review of the climate literature of that era and refute the findings of Stewart and Glantz.

They have no earthly idea why one model outperforms the other at some point nor why it stops doing so at some other time.  They just go with the absurd idea that an average of them all has some sort of physical meaning.  It doesn't.
Another way t look at is even easier to grasp.  If any model could actually show the climate change that matches the observation of the past, and predict the future (calm down, I will come back to that), then that is the model that would be used.  Because it would be a model that is useful. 

The obvious question might be

Why do the models differ at all? 


As for predicting the future, we have over thirty years now to actually compare to past models.  If they don't match what happened, (and none of them do), then we can say they were wrong.

But the problem with that is actually multiple problems. First, the observations used have been so munged by adjusting them that they no longer have any basis in reality.

Second, the past observations don't actually cover much of the world.

Third, the models differ because they don't use the same laws of physics.  And they don't actually model the real world.

Don't even.  The modelers are fucking raving mutant lunatics.  Here's what NOAA has to say for the lay audience about how the models are "validated"

How are Climate Models Tested?
Once a climate model is set up, it can be tested via a process known as "hind-casting."  This process runs the model from the present time backwards into the past. The model results are then compared with observed climate and weather conditions to see how well they match. This testing allows scientists to check the accuracy of the models and, if needed, revise its equations.  Science teams around the world test and compare their model outputs to observations and results from other models.  

So according to NOAA what you do is write a model and run it into the past while adjusting whatever you need to adjust in order to make the model fit the historical data.  Then you say that the model is validated, run it into the future and it will faithfully track the future climate.  Bearing in mind that the climate is the absolute archetype of a nonlinear dynamical system - meaning that by definition it is unpredictable.

Quote
Once a climate model can perform well in hind-casting tests, its results for simulating future climate are also assumed to be valid. To project climate into the future, the initial conditions are set to reflect a finite set of possible future conditions called scenarios. Scenarios are possible stories about how quickly human population will grow, how land will be used, how economies will evolve, and the atmospheric conditions that would result for each storyline.

I have no proper words to express how an actual scientist views this.

We have effectively the same conditions as prevailed in 1963 which triggered the great 'New Ice Age' scare of the seventies.

Yep. We still have the Yellow Press. There were a handful of researchers who made headlines with claims like these, but it did not hold up to scrutiny.
Nonsense.  Utter bollocks.


Then post a link to something other than a magazine article, concerning the ice age that was coming in the seventies.

What is it you're looking for?  Research papers, review papers, government agency releases, press articles?  There's enough to keep you reading well into the next actual ice age if you're interested in evidence rather than historical revisionism.  You could just google it yourself but you do have to get past the pages of hysterical denial.  It's become a whole fascinating subject all of its own but you might like to start with this pretty comprehensive review paper from the perspective of 1985.

The conclusions of the NDU study might have been predicted from a knowledge of the prevailing 'spirit of the times' (i.e., the prevailing mood in the science community) when the first part was conducted. This was an interesting time in recent history of climate studies. One could effectively argue that in the early 1970s the prevailing view was that the earth was moving toward a new ice age. Many articles appeared in the scientific literature as well as in the popular press speculating about the impact on agriculture of a 1-2°C cooling. By the late 1970s that prevailing view had seemingly shifted 180 degrees to the belief that the earth's atmosphere was being warmed as a result of an increasing CO2 loading of the atmosphere.  ... The causes of global climate change remain in dispute.  Existing theories of climate, atmospheric models, and actuarial experience are inadequate to meet the needs of policymakers for information about future climate.

I disagree.  The climate change now is not like the cooling measured then.

All I meant by it was that the sea froze in bitterly cold conditions at the beginning of March which is a rare thing for the UK and similar to that time of year in the fell winter of 1963.  It does however make it difficult to convince the public that they are experiencing 'runaway global warming' and why they should bankrupt themselves to make it even colder.  I actually now see the term 'runaway climate change' in use.  Now that is funny.

Also

The main reason I post events like this is for fun and because the alarmists squawk and screech at every flood, drought, heatwave, rainstorm, bush fire ... and claim they are evidence of global warming.

It's just weather but I bring it up to remind the usual lunatics that next time there is a hurricane or drought or whatever - that is just weather too.

Grown ups, like legitimate meteorologists and associated climate related disciplines find a way to deal with the issue

Sure thing.  I mean it's not like these grown ups ever got anything wrong before or anything like that.  And they certainly do always "find a way to deal with" any issue at all.
