Except for climate science I suppose. Climate models are not at all designed on the basis of physics, fluid dynamics, and mathematics. The sciences of fluid dynamics and radiative energy transfer have a definite liberal bias. :roll:


Radiative energy transfer? That sounds like a typical Commie redistribution of wealth scheme


You mean like a typical Pinko Stinko Commie redistribution scheme? I guess that would depend on whether the energy is transported upward or downward in the atmosphere.


:lol: :lol:

The global cooling myth

Filed under: Climate Science FAQ Greenhouse gases Instrumental Record Paleoclimate— william @ 14 January 2005 - ()

Every now and again, the myth that “we shouldn’t believe global warming predictions now, because in the 1970′s they were predicting an ice age and/or cooling” surfaces. Recently, George Will mentioned it in his column (see Will-full ignorance) and the egregious Crichton manages to say “in the 1970′s all the climate scientists believed an ice age was coming” (see Michael Crichton’s State of Confusion ). You can find it in various other places too [here, mildly here, etc]. But its not an argument used by respectable and knowledgeable skeptics, because it crumbles under analysis. That doesn’t stop it repeatedly cropping up in newsgroups though.


I should clarify that I’m talking about predictions in the scientific press. There were some regrettable things published in the popular press (e.g. Newsweek; though National Geographic did better). But we’re only responsible for the scientific press. If you want to look at an analysis of various papers that mention the subject, then try http://www.wmconnolley.org.uk/sci/iceage/.

Where does the myth come from? Naturally enough, there is a kernel of truth behind it all. Firstly, there was a trend of cooling from the 40′s to the 70′s (although that needs to be qualified, as hemispheric or global temperature datasets were only just beginning to be assembled then). But people were well aware that extrapolating such a short trend was a mistake (Mason, 1976) . Secondly, it was becoming clear that ice ages followed a regular pattern and that interglacials (such as we are now in) were much shorter that the full glacial periods in between. Somehow this seems to have morphed (perhaps more in the popular mind than elsewhere) into the idea that the next ice age was predicatable and imminent. Thirdly, there were concerns about the relative magnitudes of aerosol forcing (cooling) and CO2 forcing (warming), although this latter strand seems to have been short lived.

The state of the science at the time (say, the mid 1970′s), based on reading the papers is, in summary: “…we do not have a good quantitative understanding of our climate machine and what determines its course. Without the fundamental understanding, it does not seem possible to predict climate…” (which is taken directly from NAS, 1975). In a bit more detail, people were aware of various forcing mechanisms – the ice age cycle; CO2 warming; aerosol cooling – but didn’t know which would be dominant in the near future. By the end of the 1970′s, though, it had become clear that CO2 warming would probably be dominant; that conclusion has subsequently strengthened.

The climate debate is really too complicated to explain in one thread. I spent a good year or so doing a few courses about climate change/environmental geography. Don't expect to convince anybody with a few paragraphs. Its one of those things that are tl;dr to most people yet they are still willing to assert that its phoney without doing the hard research those who support it (those who aren't blindly supporting it, that is) do

Yeaahh I've done some google searches on climate change/global warming and I dunno wtf to think at all. There's way too many factors involved. But apparently there's an overwhelming scientific consensus on it being true.

Even after committing a lot of time to it I am still skeptical of some claims. Its always healthy to be skeptical. For instance I find it annoying that the time-scale that is often asserted (100 years? 20 years? 10,000 years?) doesn't seem to be consistent among many climate scientists. On the other hand, most of the skeptic scientists research is really not very good, and I don't trust oil companies to do honest research on the subject in general. Honestly I feel that a lot of the doomsaying is coming from media outlets putting words into scientists' mouths or using claims out of context- (conveniently also funded by oil companies, in many cases), because I have read many interviews with the leading proponents and they seem pretty calm about the whole thing

Yeah it's definitely always good to be skeptical. Nothing is too good to go unquestioned. Taking your word for it, it looks like there is considerable scientific controversy, though most of the controversy seems to lie in the media. btw wtf is up with the name change from global warming to climate change? There's something sketchy about that. But regardless climate change/global warming is one topic I usually stay out of.

I think it was meant to be more accurate. Some parts of the globe are supposed to become cooler, others not so much affected. I suppose they'll call it something new in a few years- 'atmospheric temperature gradient transition' (ATGT) or something :lol: they really like their abbreviations. It hurts my head, personally, to think of all the abbreviations I have had to memorize in the past in regards to this

Btw, when I mentioned media outlets taking their words out of context- I admittedly have an anti-Fox bias, but I am also against most other corporate media. Right wing media tends to out-context them in a negative light, while left wing media tends to do it in a positive light. Either side is doing the whole thing a disservice though.

I realize that providing ruveyn a source which says his bogus claim about "most 1970s scientists were global cooling believers" isn't going to suddenly convince him that anthropogenic climate change is happening. But the fact of that matter is that ruveyn and others have made this nonsense claim WAY TOO MANY TIMES and, for any impressionable third parties out there, I think it's useful to show that its a BS claim. On another web forum, in 2007, there were a bunch of BS claims about Obama being a Muslim going on the internet. While I didn't think I'd be able to convince people to vote Obama, I did find it useful to link to the Snopes page that showed the "Obama is a Muslim" claim to be bogus.

Yeah, you're right. I've had my fill of the climate debate over the past few years so excuse me for my negative attitude. Its like trying to nail jello to a wall

Badly based, because it does not weigh ALL possible climate drivers properly. Cosmic Rays which affect cloud formation are not properly factored in. Also the variations in earth orbit and earth axis tilt are not factor in properly. Also the underling dynamics is chaotic dynamics which is not modeled properly by mathematics. Chaotic systems are for the most part mathematically intractable and cannot be simplifield faithfully with linear models.

Bottom line: there is no "climate science". There are only climate models which are fitted to the political landscape to get the most funding.

ruveyn

The problem with that, Ruveyn, is that the predictions made by climate scientists decades ago are now coming to fruition with startling frequency. You may not like their methods, but accurate predictions are the best indicator of a successful model.


The "climate scientists" predicted an other little ice age back in the 1970s

The earth has not yet become like the planet Venus and if the North Atlantic halocline disappears because of fresh-water melt Europe will become much cooler than it is.

The average temperature has not risen as high as the "hockey stick" fanatics predicted.

Nor have the oceans risen 100 meters to flood the coasts.

I am still waiting for a disaster. Where is it?

ruveyn


That is totally inaccurate. In the 1970s there was no consensus on the direction that climate was heading. Unlike today. In 1975 the NAS noted the many (majority of) papers claiming that global warming was coming and the smaller number that noted that an ice age was due and said that no conclusion was currently possible and that more data was required. Today the NAS supports conclusions about global warming. You've been reading too much creationist style propaganda that has no basis in reality.

In 1900 physicists thought movement was Newtonian now they think something completely different. This proves they are wrong today.

You don't believe that the climate science is real because things haven't gotten vastly worse than the climate models predicted for this point in time? Do you understand how illogical that is?

climate change disbelief long ago moved from skepticism to denialism, and the leaders of it are now heading in the direction of conspiracy theorism.

But people were well aware that extrapolating such a short trend was a mistake (Mason, 1976) . Secondly, it was becoming clear that ice ages followed a regular pattern and that interglacials (such as we are now in) were much shorter that the full glacial periods in between. Somehow this seems to have morphed (perhaps more in the popular mind than elsewhere) into the idea that the next ice age was predicatable and imminent. Thirdly, there were concerns about the relative magnitudes of aerosol forcing (cooling) and CO2 forcing (warming), although this latter strand seems to have been short lived.

The state of the science at the time (say, the mid 1970′s), based on reading the papers is, in summary: “…we do not have a good quantitative understanding of our climate machine and what determines its course. Without the fundamental understanding, it does not seem possible to predict climate…” (which is taken directly from NAS, 1975). In a bit more detail, people were aware of various forcing mechanisms – the ice age cycle; CO2 warming; aerosol cooling – but didn’t know which would be dominant in the near future. By the end of the 1970′s, though, it had become clear that CO2 warming would probably be dominant; that conclusion has subsequently strengthened.

The climate debate is really too complicated to explain in one thread. I spent a good year or so doing a few courses about climate change/environmental geography. Don't expect to convince anybody with a few paragraphs. Its one of those things that are tl;dr to most people yet they are still willing to assert that its phoney without doing the hard research those who support it (those who aren't blindly supporting it, that is) do


I realize that providing ruveyn a source which says his bogus claim about "most 1970s scientists were global cooling believers" isn't going to suddenly convince him that anthropogenic climate change is happening. But the fact of that matter is that ruveyn and others have made this nonsense claim WAY TOO MANY TIMES and, for any impressionable third parties out there, I think it's useful to show that its a BS claim. On another web forum, in 2007, there were a bunch of BS claims about Obama being a Muslim going on the internet. While I didn't think I'd be able to convince people to vote Obama, I did find it useful to link to the Snopes page that showed the "Obama is a Muslim" claim to be bogus.

I don't think ruveyn is going to stop repeating it. We've already been there before in a previous thread. Just for that I'm going to be pre-emptive. Claims that temperatures during the "medieval warm period" were warmer than today over the entire globe are also bogus. The only way you get the "medieval warm period" to be warmer than today's measured global mean temperature is to only consider certain proxy data from Europe and the North Atlantic.

Skeptics are blatantly hypocritical when they criticize tree-ring data in one case (the data used to create the controversial "hockey stick" graph) yet refer to the very same source of data (while only considering a subset of it) to claim that the medieval warm period was much warmer than today.

It's a bit of a shame because ruveyn is not a creationist and seems reasonable when it comes to evolution. For some reason he can't see that denialists are using creationist tactics letter for letter. In many cases they are exactly the same people.

Not to stray too far from the subject of the thread, but the History Channel had run an interesting documentary a few years ago called (I believe) Big Chill, Little Ice Age. This dealt with how during much of the middle ages and after, Europe underwent what could only be described as a miniature ice age, in which temperatures dropped considerably.
