Global Warming or a New Ice Age: Documentary Film
Global cooling was a conjecture during the 1970s of imminent cooling of the Earth’s surface and atmosphere along with a posited commencement of glaciation. More on this topic: https://www.amazon.com/gp/search?ie=UTF8&tag=tra0c7-20&linkCode=ur2&linkId=d5efc8b59353d775d70007da8af41fce&camp=1789&creative=9325&index=books&keywords=global%20cooling
This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the scientific understanding of ice age cycles. In contrast to the global cooling conjecture, the current scientific opinion on climate change is that the Earth has not durably cooled, but undergone global warming throughout the twentieth century.
Concerns about nuclear winter arose in the early 1980s from several reports. Similar speculations have appeared over effects due to catastrophes such as asteroid impacts and massive volcanic eruptions. A prediction that massive oil well fires in Kuwait would cause significant effects on climate was quite incorrect.
The idea of a global cooling as the result of global warming was already proposed in the 1990s. In 2003, the Office of Net Assessment at the United States Department of Defense was commissioned to produce a study on the likely and potential effects of a modern climate change, especially of a shutdown of thermohaline circulation. The study, conducted under ONA head Andrew Marshall, modelled its prospective climate change on the 8.2 kiloyear event, precisely because it was the middle alternative between the Younger Dryas and the Little Ice Age. The study caused controversy in the media when it was made public in 2004. However, scientists acknowledge that “abrupt climate change initiated by Greenland ice sheet melting is not a realistic scenario for the 21st century”.
Currently, the concern that cooler temperatures would continue, and perhaps at a faster rate, has been observed to be incorrect by the IPCC. More has to be learned about climate, but the growing records have shown that the cooling concerns of 1975 have not been borne out.
As for the prospects of the end of the current interglacial (again, valid only in the absence of human perturbations): it isn’t true that interglacials have previously only lasted about 10,000 years; and Milankovitch-type calculations indicate that the present interglacial would probably continue for tens of thousands of years naturally. Other estimates (Loutre and Berger, based on orbital calculations) put the unperturbed length of the present interglacial at 50,000 years. Berger (EGU 2005 presentation) believes that the present CO2 perturbation will last long enough to suppress the next glacial cycle entirely.
As the NAS report indicates, scientific knowledge regarding climate change was more uncertain than it is today. At the time that Rasool and Schneider wrote their 1971 paper, climatologists had not yet recognized the significance of greenhouse gases other than water vapor and carbon dioxide, such as methane, nitrous oxide, and chlorofluorocarbons. Early in that decade, carbon dioxide was the only widely studied human-influenced greenhouse gas. The attention drawn to atmospheric gases in the 1970s stimulated many discoveries in future decades. As the temperature pattern changed, global cooling was of waning interest by 1979.

This video should be removed as it suggests reasons and rationales that have been categorically shown to be false. The evidence that CO2 emissions from all sources, not just our fractional contribution, has been shown by a multitude of data and many disciplines to be almost inconsequential to 'global warming'. CO2 levels change because of temperature change. It is exactly opposite to the foolish premise of Al Gore.
We will need greenhouses to even grow food in the near future and still this type of nonsense persists.

So here we are 3 years later at the beginning of a GSM. What are your thoughts now?
"" Other estimates (Loutre and Berger, based on orbital calculations) put the unperturbed length of the present interglacial at 50,000 years. Berger (EGU 2005 presentation) believes that the present CO2 perturbation will last long enough to suppress the next glacial cycle entirely.

TOTAL COMPLETE UTTER BULLSHIT! 50,000 year interglcial? WTF? The 'present' inter-glacial effectively ended when the medieval warm period collapsed into a 400 year cold period, the present tiny warm period only lasted as long as there was decent solar activity & now that's ending and we're about to drop down another notch into the glacial period with solar activity declining. Warming ended 20 years ago, there has been global cooling since 2006 when AlGores first movie came out and ice has been increasing in both antarctica and greenland.. and 'climate change being certain today?' what a load of shit, all the models exaggerated warming.. Global Warming scammers are such morons.
Global cooling causes sea levels to drop because so much water turns into ice.
Everyone here is intelligent enough to realize that these so called documentaries are funded by oil companies, right?
ROFLMAO, the exact opposite of what the climastrologists say today, all except for the doom, we're all doomed, in fact I predict everyone will die.
This is probably Al Gore's favorite movie.
For all you idiots who think you were supposed to die a while back just remember it doesn't take 2seconds to die from a cigarette it takes time to develop cancer ..and we the earth has been smoking cigarettes for quite some time( metaphorically speaking) these people that are telling us that the earth is going through these changes is like a doctor telling us to slow down on the damn nicotine it's killing us slowly …so please stop saying it's a fake ..this is real they have proof and they study everything they have told you people one day your kids will realize this and it will be too late for them…we are not a healthy planet and most of you are oblivious to this fact …
There are these things called cycles. (You all got that?) and these cycles happen naturally. Think about it (still with me?), these cycles happen almost like clockwork and they happen every time. Just in time for us, each one is due. The Grand Solar Minimum started a few months back, the mini ice age will start by 2019 or 2021, and the BIG ONE will probably start by 2050.
What a bunch of disinformation! This biosphere is only about 6,000 years old. The foundation of science information false, all base on science fiction theory. Can't watch such crap.
Raging wildfires and over 90 active volcanos producing far more CO2 than man ever could is driving the climate change.
they said: "begining inless than 7 years",,,,and this was made in 2011 !!!! you mean that's it? ice age begining this winter?
pretty funny to see all these pompous false predictions…
Bring it we need a thinning,Al Gore first to go,Obama,Clintons,Holder,Rice,Schumer,shitty shifty Schiff,all the asshole liers go first,by force if necessary. I think i remember this documentary from the 70's,when scientists had Honor and told the truth unlike Bill Nye the asshole guy
Note that an ice age never happened according to the timeline of this film.
What a load of shit that is nothing about science or data analysis. Nothing
Global warming a massive hoax!
Warnings of both global warming and cooling have suffered from extrapolation fallacy based on just the previous few decades of data, cooling 1940-80, warming 1980-2017.
Lmfao… Less than 7 years away! This documentary looks to be from the late 70s or from the 80s… That was 30+ years ago.
just maybe a little off I've agree by 1995😄
now don't mistake my jest as disbelief just how it comically blew up in that time frame
What a load of BS. 1995 came and went and we are no closer to an iceage, the oil hasn't run out and life goes on.
Regardless of the truth or reality, a great cult of stupidity is arising enriching certain politicians.
kig ind på varmestuen, eller bliv frelst
You can tell this is over 30 years old ,,.,even though it does describe the 70s 80s correctly
fava beans grow in -5c temp
In india from last 7 years winter was severe
Killer cold wave across country.
Its all because of climate change
Melting of many of the worlds glaciers indicates we are still coming out of the last ice age, not entering a new one.
38:30 – It's not quite true that only the trees of the world can save us. We can manufacture 'artifical trees' thats only purpose is to remove CO2 from the atmosphere, or prevent CO2 from being released. When dry they absorb CO2, but when immersed in water the CO2 is released. This expelled CO2 can be captured & then inject into porous rocks that are bounded by non-porous rocks. Not so much carbon sinks as carbon safes.
LMAO……….how OLD is this documentary? Citing Florida Citrus crops freezing from the early 1980's and "harsh" winters (no year given) from up North??? That's almost FORTY years ago. Like many commenting below, those who made this should really learn the difference between weather and climate. Weather is the atmospheric conditions of a certain day, week, month………Climate is the AVERAGE of those atmospheric conditions over an area (usually 60 km by 60 km) during an extended period (usually 30 years). So trying to use such examples does nothing but muddy the waters in the opinions of those that really don't know much about this subject.
And for the record, FUCK Al Gore, those piece of shit movies he made, and the rest of his ilk (e.g. hypocrite politicians)……..he single-handily set back the whole field of climatology decades. Leave the science to the scientists, so unless you are one the keep your mouth shut on the topic. It was a travesty that he got a Nobel prize. The sad thing, is that he wasn't really wrong with much of what he said, he just stated those extreme predictions as fact without discussing the extremely low probability of said events actually happening.
Never mind the fact that climate change ISN'T the elephant in the room……there are unknown negative feedbacks in complex adaptive system we know the climate, that will help limit the perturbation of the anthropogenic greenhouse effect. The REAL elephant in the room with respect to increased atmospheric CO2 is Ocean Acidification, and this is basic high school chemistry. As CO2 dissolves in seas water, carbonic acid is a by-product………because the carbon is bound up in carbonic acid, shelled sea life can't use it to make calcium carbonate for their shells. This, in all probability, will have a devastating impact on ocean ecosystems and biota…….and with pollution, over fishing, etc., it could just be the straw that broke the camels back. And it's a problem that we are already seeing…….I highly recommend the following NOVA program.

extra CO2 can not and does not have much effect ,because the absorption spectra for CO2 is already almost fully saturated
