I lived through this and know it was real. Remember, the alarmist back then wanted to use giant airplanes to dump coal dust on the poles and Greenland to melt the ice faster.

Yes, some of those alarmists were onboard the Human-caused Global Cooling train, and then when the temperatures started warming up in the 1980’s, they pivoted 180 degrees, and got on the Human-caused Global Warming train.

And now it’s starting to cool again. It may be time for another pivot.

Ah, yes, but you forget the interconnecting acid-rain train, that met with the chlorofluorocarbon train, to buy a ticket for the global-warming train. Which broke down before it ever left the station … due to a lack of coal.

Alarmist Climate Science is full of ambiguous descriptions.

Science is supposed to be as precise as possible. Ambiguous descriptions don’t fit this bill.

And it was being heard in middle school. Repeating the experience I told about in my May 2011 guest post at CEI’s blog,

In the mid ’70s during a school discussion of the then-current global cooling crisis, a classmate asked if I was concerned about advancing ice sheets. I replied, “No, I’m sure I can outrun a glacier.”

If I remember right, it wasn’t led by the teacher, but was instead just a spontaneous topic among us kids in our science class.

Alarmists are the tools of the new world order folks that look to control every aspect of human life. Anything to ramp up fear to gain more control be it weather or a virus.

I would say it took me about a year, after I started seeing the Human-caused Global Cooling claims in the literature, to realize they didn’t have any evidence for these claims, just unsubstantiated assumptions and assertions.

I was willing to give the alarmists the benefit of the doubt, and I kept waiting and waiting, but they never produced anything close to definitive evidence of what they claimed, and it frustrated me to no end.

What really was frustrating to me was them using speculation as established fact. And publications like Scientific American were putting this BS (Bad Science) out. I wish the internet had been available back then. I would have blistered someone’s ears/eyes.

And now we have the exact same situation with Human-caused Global Warming. It’s promoters have never produced one shred of evidence backing up their claims. Yet the world carries on as if they have.

A few comments above you state that cooling is starting to happen, without a shred of evidence apart, I guess, from a few years of data post an El Nino event. If you have some strong evidence, I want to see it. Otherwise , you’ll have to wait to see if your speculation is correct.

… use the degree symbol with Kelvin

I keep getting conflicting “advice” on this issue, maybe someone here can point me (and everyone else …) to the “definitive” answer ?

1) Absolute temperatures : Use “Kelvin” or “degrees Celsius / Fahrenheit”

0°C = 32°F = 273.13K

2) Differences in temperature : Use “degrees K” or “C / F degrees” (?!)

1 = 1.8F° = 1°K

Reply to  Mark BLR
December 24, 2021 2:27 pm

I don’t know a definitive answer to your question, but I think the best answer is probably to just make sure your prose is clear. E.g., if you mean “difference in temperature of…” say “difference in temperature of…”.

A nit: I think you meant:

0°C = 32°F = 273.15K

December 24, 2021 6:45 am

I lived through this, in Northern Minnesota, even walking to school one morning (3 blocks) when the radio reported the temperature was minus 53 degrees F. We all thought this was simply normal, and it ignored the scare stories. I even filled a glass jug with green chlorine gas and left it on the back porch to liquify (at around -40) but it was March by then, and never got that cold.

The CIA report on global cooling had the same dire predictions as they now make for global warming. One brings death the other more food.

Here’s a 1974 CIA report: (or here)

This one appears to be a different scan of the same document:

I think that’s the report referred to in the 1976 news article. My guess is that it was prepared and dated in 1974, but not released until 1976.

(Or, was there another CIA climate report in 1976?)

Here’s an excerpt, from the Summary:

“The western world’s leading climatologists have confirmed recent reports of a detrimental global climatic change… during 50 of the last 60 years the Earth has, on the average, enjoyed the best agricultural climate since the eleventh century… The world is returning to the type of climate which has existed over the last 400 years. That is, the abnormal climate of agricultural-optimum is being replaced by a normal climate of the neo-boreal era. The climate change began in 1960…”

The grim climate to which we were thought to be returning was the Little Ice Age. “Boreal” means cold:

boreal. adj. Relating to or characteristic of the climatic zone south of the Arctic, especially the cold temperate region dominated by taiga and forests of birch, poplar, and conifers…

 ‍‍‍‍‍‍ ‍‍

This was a different report, from the same time period:

Here’s an excerpt:

In general, the period about 7000 to 5000 years ago was warmer than today, although the records of mountain glaciers, tree lines, and tree rings reveal that the past 7000 years was punctuated in many parts of the world by colder intervals about every 2500 years, with the most recent occurring about 300 years ago.

 ‍‍‍‍‍‍ ‍‍

The U.S. National Academy of Sciences also published a long climate report, the following year:

Here’s an excerpt:

A striking feature of the instrumental record is the behavior of temperature worldwide. As shown by Mitchell (1970), the average surface air temperature in the northern hemisphere increased from the 1880’s until about 1940 and has been decreasing thereafter (see Figure A.6, Appendix A). Starr and Oort (1973) have reported that, during the period 1958-1963, the hemisphere’s (mass-weighted) mean temperature decreased by about 0.6 °C. In that period the polar and subtropical arid regions experienced the greatest cooling.

Here’s another excerpt:

In summary, we may say that observational data at the earth’s surface show that during the period 1900 to 1940 the northern hemisphere as a whole warmed, although some areas (mainly the Atlantic sector of the Arctic and northern Siberia) warmed far more than the global average, some areas became colder, and others showed little measurable change (Mitchell, 1963). In the time since 1940, an overall cooling has occurred but is again characterized by a geographical structure cooling since 1958 has occurred in the subtropical arid regions and in the Arctic (Starr and Oort, 1973). There is also some evidence that the northern hemisphere oceans are cooling (Namias, 1972b), although the oceanic data base necessary to confirm this has not yet been assembled.

 ‍‍‍‍‍‍ ‍‍

Here’s a paper that it referenced:

Here’s the abstract:

The trend of world temperature in this century appears to be directly related to the trends of atmospheric carbon dioxide content and atmospheric turbidity (dustiness). Both are believed by various scholars to be related to human activities. Since 1940, the effect of the rapid rise of atmospheric turbidity appears to have exceeded the effect of rising carbon dioxide, resulting in a rapid downward trend of temperature. There is no indication that these trends will be reversed, and there is some reason to believe that man-made pollution will have an increased effect in the future.

 ‍‍‍‍‍‍ ‍‍

It is interesting and disturbing that some of the papers referenced in those reports seem to have simply disappeared, like this one:

Mitchell, J. M., Jr. (1974). The global cooling effect of increasing atmospheric aerosols, fact or fiction? Proc. IAMAP/WMO Symp. Phys. and Dyn. Climatol. (Leningrad, USSR, August 16-20, 1971), World Meteorological Organization, Geneva (in press).

Dear Mr. President:

Aware of your deep concern with the future of the world, we feel obliged to inform you on the results of the scientific conference held here recently. The conference dealt with the past and future changes of climate and was attended by 42 top American and European investigators. We enclose the summary report published in Science and further publications are forthcoming in Quaternary Research.

The main conclusion of the meeting was that a global deterioration of climate, by order of magnitude larger than any hitherto experience by civilized mankind, is a very real possibility and indeed may be due very soon.

The cooling has natural cause and falls within the rank of processes which produced the last ice age. This is a surprising result based largely on recent studies of deep sea sediments.

Existing data still do not allow forecast of the precise timing of the predicted development, nor the assessment of the man’s interference with the natural trends. It could not be excluded however that the cooling now under way in the Northern Hemisphere is the start of the expected shift. The present rate of the cooling seems fast enough to bring glacial temperatures in about a century, if continuing at the present pace.

The practical consequences which might be brought by such developments to existing social institution are among others:

(1) Substantially lowered food production due to the shorter growing seasons and changed rain distribution in the main grain producing belts of the world, with Eastern Europe and Central Asia to be first affected.

(2) Increased frequency and amplitude of extreme weather anomalies such as those bringing floods, snowstorms, killing frosts, etc.

With the efficient help of the world leaders, the research …

–- and so on —

With best regards,

And what is happening now, the end of coal, manufacturing, natural gas hookups, actually phasing out the internal combustion engine and gasoline simply didn’t have a counterpart in the 70’s. PS My conspiracy theory mind goes into overdrive when biofuels were introduced that would make gas “environmentally friendly”…but also give gas a “shelf life”, precluding long term storage.

I do not remember any of these articles, but I do have a personal experience from that time.

I came to Timmins Ontario in the middle of September 1976 to work for a year in the mining industry. The snow came the last day of September and did not leave till the middle of May 1977 and it was cold. I remember nights of -60C and changing tire with bare hands where my fingers almost froze on the lognuts.

Just a personal anecdote to validate that it was indeed cold in the mid 70’s.

Mr. 76: Thanks for that. My own experience included living in NE Ohio before ’77-’78, SE Ohio after; and four years in Milwaukee. Those were the worst winters in all three regions for many, many years, before and after. The coming ice age was in the news, and even back then the news knew which “experts” to interview. When those same experts later flipped to AGW the news folks never noticed the contrast. I learned a great deal from watching enviros and the press perform duets for the last 5-6 decades.

We’d have weeks of -30c or colder and when we’d get a little chinook from Alberta and the temp came above freezing for a day we’d all run around without coats celebrating like it’s some sort liberation.

I have my mom’s photo albums, year after year of massive snow drifts that we could tunnel in to standing up, all ended in the winter of 81-82 thankfully.

And based on the mindset and verbiage of the climate Scientologists this is what they want to somehow force us back to, not possible but it shows the level of insanity present in all these people.

I am so ancient and clearly recall attribution to smog/aerosols from burning fossil fuels, hence the subsequent bans on domestic coal burning and generation with fuel oil. And lo the trend reversed, warming came about. Attribution? Again, burning fossil fuels, now producing CO2 etc. Always the fossil fuels! Apparently started by the nuclear industry, of which James Hanson was a supporter. Now it’s driven by world socialism and desire to control our mobility and life-styles. Increasingly appears however that it is all part of long term ocean current phases, as hinted at by climate-gate icons Phil & Mick. All will be revealed like the quarks, as the trillion funded

The cooling was certainly real. Their attribution to aerosols seem to have been based primarily on assumptions though. There appear to be periodic, quasi-cyclical warming and cooling periods which have nothing to do with man. Not least because human activity can contribute to both warming and cooling. It is therefore laughable nonsense to try to say that man can affect climate to any great degree. That certainly doesn’t stop the charlatans though, from doing just that.

If I may, as to “a periodic cyclic warming and cooling”, the Pacific Decadal Oscillation was discovered by a biologist from Univ. of Wasington in about 1997, when he was studying salmon returns to their home rivers in BC and Alaska and Washington state. He found that there are two regimes to the warmthh of the northren pacific waters. Each regime lasted for about 20 to 30 years, with few years in the middle. This toggling mechanism coincided with the 1970 centered cool period and the warming out of that was to be centered around 1990-2000. He found that when the northern Pacific was warm, the central USA was cool (and salmon counts were high), and when the northern pacific was cool the central USA was warm (and salmon counts were low). The SE USA was in phase with the warm or cool northern Pacific.

The blacktop effect mitigated cooling. The Greenhouse effect is forcing greening. The temperature evolves in space and time with an impulsive orientation (e.g. recurring blocking events that force statistical anomalies).

Late ’70s, the CBC National, then hosted by Peter Mansbridge, ran a roughly 10 minute documentary during its evening news hour about what seemed to be the return of the ice age, narrated by Adrian Clarkson…I know this because I watched it.

Shortened growing seasons, global crop failures, increasingly severe winters, etc., the end of the world as we know it is nigh.

Good luck trying to find this in the CBC archives! I can’t find it…but maybe someone here is better at such searches than I???

That should read “Adrienne Clarkson”.

“Everybody complains about the weather nobody does anything about it.”
It’s still true that nobody CAN do anything about the weather.
But some have learned to profit from it by pretending they can.

Earth is colder when the solar wind is stronger, as in the early to mid 1970’s, because ENSO and the AMO change inversely to changes in the solar wind strength. The AMO was much colder, and there were multi-year La Nina conditions, but the UK and Europe were toasting, so was California. That’s all driven by a positive NAO/AO regime.

Attribution to a cooling effect from industrial aerosols is highly questionable, as low altitude aerosols exacerbate land heatwaves considerably. As with the hot UK summer of 1783 with fumes and dust from the Laki eruption, heavy industrial air pollution with the record high UK max temperatures in Easter 2011 and through 22-27 Feb 2019, the Moscow 2010 summer heatwave with forest fire smoke in the air, and in Syracuse Sicily in August 2021 with fire smoke.

I loved those winters.

I know it was real from its imprint on popular culture. There are a few cartoons and some sci-fi short stories that I saw and read in the 1980s that prominently featured pollution causing global cooling, and either leading to an ice age or or a world covered in soot and smog.

Since I was only 4 in 1980, I don’t remember the height of the scare, but those artifacts left an impression on me as a child.

One thing I remember was that Woods Hole Oceanographic Institution was at the enter of that, and the very same Woods Hole was a leader when the flipped to alarmism about warming. A second center of that was East Anglia, and they, too flippedd when flipping was a bigger bandwagon, but early on. Cooling didn’t make for grant money, as I have underrstood it over the years. But warming sure did.

Like others here, I remember the period from the winter of 1976-77 all the way through the winter of 1984-85 was freaking HORRIBLE cold, and not a little bit of blizzard-like weather. That last winter, between Rockford and Chiaggo in my town the temp got down to -34F. I NEVER want to do that again. I had lived at the same latitude for most of the previous decade, and had not run into anything like that period. I simply could not figure out why Chicago was so darned frigid – shortly after I got there. I’d never heard of it being THAT cold.

It was just as cold in the decade of the 1910’s as it was in the decade of the 1970’s, according to the unmodified, U.S. surface temperature chart.

The temperaures cooled from the 1880’s to the 1910’s, then warmed to the 1930’s, then cooled again to the 1970’s, then warmed again to 1998, then flatlined (discounting El Nino’s) to 2016/2020, and have cooled 0.6C since that time.

The cooling from 1940 to 1980 was equivalent to about 2.0C of cooling (according to the US chart). So the 0.6C of present cooling means we are about 1.4C away from the temperatures of the 1970’s.

Here’s the U.S. surface temperature chart (Hansen 1999), shown next to a bogus Hockey Stick chart. Note the differnce in cooling from 1940 to 1980, on both charts. The Hockey Stick chart downplays the amount of cooling that took place during this period.

Hi Tom
It’s more insidious than that.
The left graph is the USA, right graph is the world.
The USA has the best continuous records but doesn’t show the right info. Since modified which you can see if you go on the GISS website and graph the same 5 year mean 1880-2000

The world graph is made up of data points that are primarily cities, the only place they kept even partial records in most of the world.

And so of course that World graph is pretty much entirely UHI corruption

I was taught this shiite in high school and that the world would run out of oil energy , made me think its the the end of the world , no point in having children etc . How times have changed but not peoples thinking .

Ironically, much of what was said about the dangers of cooling (now falsely being attributed to “climate change”) was true. Cooling is in fact, far more dangerous, although we can certainly adapt, and have far more of the capability to adapt now. Good thing, because cooling might be coming, if not already here. How much cooling no one can predict, but another LIA type of cooling is certainly possible. We should be planning for that by doing the complete opposite of what the Climate Caterwaulers want us to.

Calling is not possible it is inevitable

A new glaciation period is also inevitable
They just jumped the gun by looking at the previous 30 years and then extrapolating forever.

Now where else have I read something similar

Three different thoughts come to mind.

1) In 1973 I was in third grade. I remember the teacher telling us that a new ice age was coming. She wasn’t alarmed and she didn’t blather on about it, she just mentioned it as an apparently established fact. I specifically remember this because I was fascinated at the idea even at that young age. I imagined big cities in constant winter conditions and wondered how we would all deal with it.

2) While in college, one of my geology professors told the class that if a process takes less than ten thousand years to occur, geologists refer to it as “instantaneous.” Current and near-term conditions matter to human beings, but arguing about trends that occur over years or decades or even centuries is pointless.

3) The trap that too many people seem to fall into is, “If this trend continues….” That was the main reason for the global cooling scare, and that’s the main reason for the global warming scare. The trend never continues! It’s a “trend!” Trends go up, trends go down, trends fluctuate. Much peace and sanity would ensue if people realized the nature of trends.

I remember it very clearly- and all the experts who so damn sure about it. Makes all this politicized “science” clear for the junk it is. It’s incredibly frustrating that they just keep on lying and lying and lying.
