What I believe is irrelevant, and please don't be condescending. I've done science for most of my life and had the word "scientist" in my job title for a good part of it.

The article talks about "climate change" since the 1960's, but it's obviously lumping in cooling and warming without distinction, which is misleading.

By limiting your engagement, you are slamming the door on debate and discussion, which is the same game that all climate change alarmists play. Science is never about consensus, it's about a cycle of theory, experiments (where possible), and analysis.

Galileo and Einstein were both victims of consensus.

TLDR: The book "The Discovery of Climate Change" by Spencer Weart dedicates an entire chapter to fitting the global cooling coverage you remember into the wider history of today's consensus, and I think it will address that much more satisfactorily for you than anyone here can.

Edit: Or one quick one about cooling specifically:

>There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age. Indeed, the possibility of anthropogenic warming dominated the peer-reviewed literature even then...When the myth of the 1970s global cooling scare arises in contemporary discussion over climate change, it is most often in the form of citations not to the scientific literature, but to news media coverage.

I wrote a different reply and deleted it in hopes of taking a completely different direction rather than just try to argue the points here. My dad remembered the same new coverage and had (I think) the same questions as you, and eventually he got his questions answered in a way that satisfied him in understanding the present day scientific consensus about climate change.

On a board like this you're always going to get terse responses to what you are asking about because to most people here it is akin to demanding that they, individually, win a debate that electricity is safe before you will use your light switch. There is no shortage at all of literature by so many sources specifically to address what you are asking about. Highly qualified people have labored exhaustively compiling the present day evidence for climate change, how it was gathered, how consensus has changed over time. Many people remember the global cooling controversy of the 70s and have asked your exact kind of question many times before. A quick google found this reply on /r/askhistorians[0], and that reply just links a post from 2005[1] which itself cites Spencer Weart's History of Global Warming, since republished as The Discovery of Global Warming, which dedicates a whole chapter specifically to 1970s "global cooling" claims.[3] These kinds of sources are going to be much better equipped and better qualified to explain the facts to you than an internet commenter, and since they've already spent the effort, why should some stranger on this board do it? Especially since this information is already easily available to you! I am not a researcher, or an expert, I didn't have this all immediately on hand. I'm sure you will have stringent standards to apply to select your sources, but even still I suspect you will be able to find enough scholarly works you find sufficiently trustworthy to build a good understanding of how "global cooling" on cable news in the 70s fits into the bigger story of reaching today's scientific consensus about climate change, without somehow contradicting all of it.

Spencer Weart is not an "alarmist playing a game," he provides an extremely thorough analysis of how this science was discovered. The internet records many instances of these positions being investigated and debated without the door being slammed in anyone's face. The refusal of a random internet commenter to retread the exact same debate here today doesn't make them an alarmist and it doesn't say anything about the validity of the general consensus for climate change. The popular debate about climate change has been held and reheld so many times that today scientists ask why there is still such an ongoing popular debate despite so many years of such broad scientific consensus.[4]

The sources linked by the commenter you replied to would probably help too, and my hope is their offer of a "limited engagement" would include a discussion of those sources - which I would be interested to read. But personally, I am not going to debate the viewpoints of these sources with you, and it's not because I'm playing the game, it's because I can't explain this stuff half as well as the original authors, and I especially can't attempt to do that with anyone who's unwilling to even read what they have to say before debating the consensus viewpoint. I really think the Spencer book is a good place to start - he's a historian of science first and foremost, has been for decades.

Please see my above reply citing over two dozen contemporaneous articles from reputable sources and scientists about global cooling ~50 years ago. Can you cite even a few articles or papers from the same era on the topic of global warming?

So much for the consensus argument, but why are you using it anyway? Science has nothing to do with consensus.

The Spencer Weart book you cite appears to be a "history of scientific discoveries that led to the current scientific opinion on climate change." I will give it a read, but I am reminded of this presentation: (You Have No Idea How Wrong You Are)

> Can you cite even a few articles or papers from the same era on the topic of global warming

Yes, the citations of the article I linked in my edit, the one you requoted, are absolutely full of them. The article also specifically addresses the "cooling consensus" some people perceived from media coverage and compares it to the reality of what was being published and cited at the time academically (note many of the sources you linked are newspaper articles, not journal publications). In particular, refer to the section starting at page number 1329:

>Survey of the Peer Reviewed Literature

>One way to determine what scientists think is to ask them. This was actually done in 1977 following the severe 1976/77 winter in the eastern United States. “Collectively,” the 24 eminent climatologists responding to the survey “tended to anticipate a slight global warming rather than a cooling” (National Defense University Research Directorate 1978). However, given that an opinion survey does not capture the full state of the science of the time, we conducted a rigorous literature review of the American Meteorological Society’s electronic archives as well as those of Nature and the scholarly journal archive Journal Storage (JSTOR).

>The survey identified only 7 articles indicating cooling compared to 44 indicating warming. Those seven cooling articles garnered just 12% of the citations.

On page number 1332, you will find an entire table "Cooling, neutral, and warming papers as defined in the text followed by the number of times they have been cited up through 1983."

The book also of course cites lots of research over the decades that built to this consensus, a consensus originating from many reputable sources and scientists individually studying global warming. I'm don't agree with the climate change consensus in a vacuum, but on the basis of the real story of how the consensus was reached from real research that I am trying so hard to point you in the direction of.

I'll just refer back to my original remarks that it's pretty much impossible for anyone to discuss these points with you if you won't do the reading. I said above I'm not interested in a personal back and forth about this point. I already gave you what you asked for in this reply in an earlier source, and I'm not going to keep replying any further now. Enjoy the book, but if all you need to be convinced is peer reviewed research into global warming from the 70s-80s it is readily available online. Below are just two examples I pulled from that article and a web search.

M. I. Budyko (1977) On present-day climatic changes https://www.tandfonline.com/doi/pdf/10.3402/tellusa.v29i3.11...

>Thus, one should recognize the possibility of rising mean air temperature within the next quarter of the century. Then the calculations carried out using different models of climate theory show that in this case the boundary of polar ice will appreci- ably recess to the north. The available data show that this warming, possibly began in late or even mid-1960s

> It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980s.
