Arctic Ocean periodically ice-free 6000 to 7000 years ago

But let’s not forget, there was no human-produced CO2 6000-7000 years ago.

1980 lies at the end-point of a well-known 30-year global cooling period which ran from about the mid-1940s to the mid-1970s.
During those three decades, some 20% of all the manmade CO2 ever produced (up to date), was emitted into the atmosphere.

Warming alarmists who maintain CO2 is the principal climate driver cannot reconcile the emission of nearly 100 gigatonnes of manmade CO2 coinciding with a corresponding period of cooling.

According to Alekseev et al. 2016 (and as you might expect after that 30 years of cooling) there was actually more Arctic sea ice in 1980 than at ANY other time during the 20th century.

So using that particular date as a starting point is useful if your aim is to accentuate the appearance of recent warming.

In any event, the Arctic ice cap is an intermittent feature. It comes and goes over millennia, and even over decades.

American nuclear submarines surfaced at an almost ice-free North Pole in 1959 and 1962. And yet by the 1999, the same region was an almost impenetrable field of sea ice.

Research into beach ridges on the northern coastline of Greenland show that 6000-7000 years ago the Arctic Ocean must have been periodically ice free all the way to the north pole for long periods of time.

But let’s not forget, there was no human-produced CO2 6000-7000 years ago.

Interestingly, according to the Danish Meteorological Institute, from 2006 to 2019 Arctic sea ice volume remained essentially constant (in fact a very slight rise may have occurred).

Once again, during this 13-year period around 20% of all the CO2 ever produced by humans was emitted into the atmosphere – and yet it had no effect on the Arctic ice cap.

So the volume of Arctic sea ice is irrelevant as far as human-induced ‘climate change’ is concerned. It comes and goes irrespective of our CO2 emissions. It’s clearly a natural variation.

Antarctic ice data is more difficult to track down but it’s understood that southern hemisphere sea ice increased strongly in the 40 years up to 2014, when it suddenly and inexplicably declined. (During that 40 years about 60% of all the CO2 ever produced by humans was emitted into the air. Yet the Antarctic sea ice grew.)

But in attempting to explain that sudden reduction in sea ice in recent years, it should be remembered that Western Antarctica and the West Antarctic Peninsula were only very recently discovered to be the home of the largest volcanic province on Earth.

In 2017 University of Edinburgh scientists identified 138 volcanoes, some as tall as 3,800 metres, buried under the ice. An increase in activity in this enormous volcanic province would doubtless be a significant factor affecting water temperature and sea ice.

So, this is why I and so many like me think it’s important that we set aside human CO2 from time to time and take a good look at the bigger picture.

Solar cycles, ocean currents, and volcanic heat are affecting Earth’s energy balance all the time, and always have.

Human influence, by comparison, is trivial and difficult even to detect.

None of the apocalyptic predictions of climate alarmism have eventuated. Not one.

The much-vaunted climate emergency therefore has no basis in science.

  1. Heck I never listen to these idiots anyway. Actually the Antarctic sea ice is currently more extensive than it was back in 1980.

  2. Very good data in these reports. Im lining them up for the election were having around these parts in a couple of months. Then Ill show or email them to some candidates..theyll get an ear full.

  3. “1980 lies at the end-point of a well-known 30-year global cooling period which ran from about the mid-1940s to the mid-1970s.”

    Yes – it falsifies the impression of the post-1980 period.

    Climate is generally understood when viewed in windows of at least 100’s of years – not that an abrupt change cannot occur – especially in a period of very active volcanism occurs which in turn drastically reduces Solar Irradiance from reaching Earth’s surface.

  4. No large scale CO2 production. Brush and camp fires, breathing and that is about it.

    Next to other sources human CO2 production is trivial.

  5. it is sad you can spend a life time trying to educate today’s brain washed young what is really happening in our world

  6. and mention the prior icemelts when man wasnt around???
    and get a blank stare or a that isnt the issue now response
    the other day some twerp was saying the little ice age and warming period were ONLY localised events..
    yeah..really?
    not.

  7. The antarctic decline was a response to the 2015-2016 back to back el nino. It restores usually after 3-4 years.

    Exactly what is happening

  8. If, as popular science has it, this planet in the last 180 years or so, has moved out of the Little Ice Age (LIA) then why is there still a large icecap at the North Pole?
    Surely after all that time the planet should have warmed enough to banish those ice fields, defrosted much of the Arctic tundra, and made Greenland more like the green and hospitable land it once was. But no!
    For nearly 200 years the climate has just very, very slightly move away from the LIA, for nearly 200 years this planet has been on the edge of slipping back to a cooler regime. For nearly 200 years the warming of the planet has been slow and weak!
    With the sun’s output currently in the doldrums it appears we all should be preparing for colder and more brutal times ahead. So get prepared now, start by reading ‘Climate Revolution’ a book by David DuByne. The last half of the book is about solutions we can all use to prepare for the inevitable shift in society.

  9. I still think the issue of ocean currents has not had the look in it deserves. The specific heat capacity of water is well above that of air, despite how much or how little CO2 is present. My own hunch is that ocean currents have a life of their own and coal burning and cow farts mean nothing here. Salinity of water? I’d say important. All sorts of things may influence our experienced climate and it is too one dimensional to focus on carbon dioxide to the exclusion of all other factors.
    Greta means well but when Stockholm becomes a tent city full of drug abusers and people defecating in public due to economic mismanagement and failure to see reality then there could be much loss of life.
    Healthcare suffers the same one dimensional blinkered vision. Covid occludes everything else both in news media and medicine. Cancer does not take a holiday like your children did from school now does it?
    Meanwhile I wait patiently for the dentist to get back to me. . . and wondering how much money I must offer him to get seen. All appointments at the doctor’s and dentists have been cancelled because of the virus in the same way all cars must now run on batteries to curb CO2 emissions.
    Feeling most nauseated.

  10. “Research into beach ridges on the northern coastline of Greenland show that 6000-7000 years ago the Arctic Ocean must have been periodically ice free all the way to the north pole for long periods of time.”

    Does somebody have a link for this paper?

    • Hi Eric.
      Yes, you can read more in a 2008 Science Daily article, covering research which comes from the Geological Survey of Norway.
      Here’s a link:
      https://www.sciencedaily.com/releases/2008/10/081020095850.htm

      Here are some quotes from the article:

      ”The climate in the northern regions has never been milder since the last Ice Age than it was about 6000-7000 years ago. We still don’t know whether the Arctic Ocean was completely ice free, but there was more open water in the area north of Greenland than there is today,” says Astrid Lyså, a geologist and researcher at the Geological Survey of Norway (NGU).

      ”The beach ridges which we have had dated to about 6000-7000 years ago were shaped by wave activity,” says Astrid Lyså. They are located at the mouth of Independence Fjord in North Greenland, on an open, flat plain facing directly onto the Arctic Ocean. Today, drift ice forms a continuous cover from the land here.
      Astrid Lyså says that such old beach formations require that the sea all the way to the North Pole was periodically ice free for a long time.
      ”This stands in sharp contrast to the present-day situation where only ridges piled up by pack ice are being formed,” she says.

      The Little Ice Age, with some of its lowest temperatures experienced in the 1600s, was the coldest period of the Holocene era.
      In other words, since the early 1700s the world has been slowly emerging from its coldest episode since the end of the last major glaciation – roughly 11,000 years ago.
      The recent warming is natural (having started long before human CO2 could have been a factor, which it isn’t anyway!) and has been a welcome recovery from a lengthy period of miserably cold conditions.

      Changes in the Sun and in the Earth’s orbital parameters are ultimately responsible for our climatic variations, but you can’t tax sunshine, can you? And you can’t assume control of Earth’s orbit and axial tilt for political purposes either, can you?
