Climate – Natural Change for over 4 billion years!

Contrary to what climate alarmists would have you believe there are many very well qualified scientists who do NOT accept that man is responsible for the global warming which has occurred over the last 200 years and especially since the last world war. The brave ones speak out.  Many more would speak but for fear of being ostracised and accused of heresy before an inquisition reminiscent of a modern medieval age. They simply cannot risk their careers; as is well demonstrated by the treatment meted out to some of the brave “heretics” who have taken the risk.  A common ploy used against those who do speak out is to claim that such scientists have received funding from the “fossil fuel industry” etc. which, even where such cases may occur, ignores the fact that government and “green industry” funding of the accepted established church view is very many times more!  In any event, science should stand or fall on its own merits, ie the facts, irrespective of the source of funding for the person or organisation that demonstrated them – or indeed whether they be many or few.

This page shows a few well researched lectures to demonstrate that there is very sound scientific evidence in support of natural causes for climate change, sometimes quite sudden, and most of which relate to the cycles of the sun as well as variations in the earth’s orbit and declination to the sun (Milankovich cycles).

I originally compiled this piece to give a degree of balance for the benefit of some local students researching the subject. I hope you may find it of interest.

Almost all media promotes the idea of dangerous man-made global warming – it is somewhat of a risky business to do otherwise!  In 2018 in England the BBC was criticised for giving a “platform” to views which did not conform to the so-called accepted consensus and since then contrary views have effectively been stifled.

However, as you will see, there are still a good number of scientists who do not accept the so called consensus – and are prepared to say so!

Here is a good place to start; just 5 minutes:


And here is a more detailed (half hour) lecture given by Dr. Christy (Distinguished Professor of Atmospheric Science and Director of the Earth System Science Center at The University of Alabama in Huntsville and recipient of NASA’s Medal for Exceptional Scientific Achievement) speaking in Paris in May 2019:




I would just mention a few points which are worth remembering.

Although the climate is always changing, in general colloquial use, the term “Climate Change” is frequently a euphemism for what used to be called “Man-made Global Warming” (sometimes called Anthropogenic Global Warming or AGW).  In recent years, maybe because some of the scare stories have become harder to promote, instead of Global Warming the term Climate Change is now used but it is generally intended to imply Climate Change caused by man-made carbon dioxide or CO2. Most recently, presumably to excite the general population even more, the term “Climate Emergency” has also come into vogue.

Some four hundred years ago Galileo was imprisoned for heresy: he dared to question the “settled science” of the day  which was that the sun revolved around the earth.  Amazingly, this archaic way of thinking (ie the concept of heresy) is being replicated in the modern world regarding Climate Change where some leading scientists, who consider that climate is changing naturally, are called Sceptics or “Climate Deniers” and have even been accused of mass murder of future populations!   The BBC, once lauded for its impartial reliability, today has a policy of not allowing the established view to be questioned.  The leading group promoting the idea of man-made climate change is the IPCC which stands for the “Inter-governmental Panel on Climate Change”. This is a UN sponsored political organisation. This business has become very political rather than scientific as it should be. So, sad to say, you should at least be aware that if you do not adhere to the popular view of the day you may be mocked or criticised by the dominant alarmist lobby.  Yet the sceptical view is becoming ever more prevalent among the population at large which is increasingly doubting the politically correct establishment propaganda on a wide range of subjects.

Remember all of the forecasts for the future are based on computer models and, given the complexity of the climate, forecasting even a few years, or indeed months, into the future is well-nigh impossible.  This is a major area of dispute between climate alarmists and climate sceptics.  The alarmists are using forecasting models which, because of such incomplete knowledge, have many uncertainties built in whilst the sceptics seek to rely on known factual data from the past up to the present day.  Of course the sceptics are also very critical of the alarmists who are trying to shut down discussion by saying there is a scientific consensus and that the issue is all agreed and settled. It only requires just one scientist to demonstrate that a theory is wrong to overturn the views of a 1000 others.

So here is a selection of lectures given by some well qualified scientists who have been brave enough to speak out.  Such men and women are often heavily criticised and even lose their university posts as a result. I have set out their professional CVs to show that they are indeed well qualified to speak.

Professor Bob Carter was a Fellow at the Institute of Public Affairs (IPA, Melbourne). A palaeontologist, stratigrapher, marine geologist, environmental scientist and writer with more than 40 years professional experience, and held degrees from the University of Otago (New Zealand) and the University of Cambridge (England). He held tenured academic staff positions at the University of Otago (Dunedin) and James Cook University (Townsville), where he was Professor and Head of School of Earth Sciences between 1981 and 1999.

Bob has wide experience in management and research administration, including service as Chair of the Earth Sciences Discipline Panel of the Australian Research Council, Chair of the national Marine Science and Technologies Committee, Director of the Australian Office of the Ocean Drilling Program, and Co-Chief Scientist on ODP Leg 181 (Southwest Pacific Gateways). He was Chief Science Adviser to the International Climate Science Coalition and an Emeritus Fellow of the Institute of Public Affairs.


“Climate Context as a basis for Better Policy” The first 30 minutes or so of this lecture in particular clearly demonstrate that late 20th century climate change was in no way unusual when compared with the past.



Prof. Bob Carter answers questions about climate change on this page.


Dr. Timothy Ball is a renowned environmental consultant and former climatology professor at the University of Winnipeg, Manitoba, Canada.  Ball is also Chief Science Advisor of the International Climate Science Coalition and a Policy Advisor to The Heartland Institute. With a doctorate in climatology from the University of London, Queen Mary College, England, Dr. Ball’s comprehensive background in the field includes a strong focus on the reconstruction of past climates and the impact of climate change on human history and the human condition.

Dr. Ball in effect accused IPCC lead author Michael Mann of fraud for producing research which sought to hide the well documented Medieval Warm Period and the following Little Ice Age which embarrassed the climate alarmist case as they occurred before the 20th century rise in CO2. Due to its shape, Mann’s graph became known as the Hockey Stick and was prominently cited by the IPCC to “prove” man-made climate change. In a long drawn out legal case for defamation taken by Mann, he then refused (for fairly obvious reasons!) to produce his data and workings resulting in 2019 with his case being thrown out. Ball was also awarded all his costs of defence.  The British state broadcaster, the BBC, appears to have overlooked this significant piece of news.




Dr. John R. Christy holds a PhD (1987) in atmospheric science from the University of Illinois. He is currently Distinguished Professor of Atmospheric Science and Director of the Earth System Science Center at the University of Alabama in Huntsville where he began studying global climate issues in 1987. Since November 2000 he has been Alabama’s State Climatologist. In 1989 Dr. Roy W. Spencer (then a NASA/Marshall scientist and now a Principle Research Scientist at UAH) and Christy developed a global temperature data set from microwave data observed from satellites beginning in 1979. For this achievement, the Spencer-Christy team was awarded NASA’s Medal for Exceptional Scientific Achievement in 1991. In 1996, they were selected to receive a Special Award by the American Meteorological Society “for developing a global, precise record of earth’s temperature from operational polar-orbiting satellites, fundamentally advancing our ability to monitor climate.” In January 2002 Christy was inducted as a Fellow of the American Meteorological Society.

Jasper Kirkby is a British experimental particle physicist currently with CERN. He originated the idea for the Tau-Charm Factory, an accelerator now under construction as BEPC II in Beijing. He has led several large particle accelerator experiments at SPEAR; the Paul Scherrer Institute; and most recently, the CLOUD experiment at CERN.

This talk presents an overview of the palaeoclimatic evidence for solar/cosmic ray forcing of the climate, and reviews the possible physical mechanisms.  It is interesting in showing the complexity of the subject and how little is still understood about forecasting the future. I believe he had to be quite careful in voicing some of his views.





Judith A. Curry is an atmospheric scientist and climatologist. She holds a PhD (1982) in geophysical sciences from the University of Chicago. She has taught at the University of Wisconsin, Purdue University, Pennsylvania State University, the University of Colorado at Boulder, and Georgia Institute of Technology (Georgia Tech). In 2017, under a torrent of criticism from her colleagues and negative stories in the media, she was forced to take early retirement from her position as Professor in the School of Earth and Atmospheric Sciences at Georgia Tech, a position she had held for 15 years (during 11 of those years, she had been Chair of the School). Curry is currently Professor Emerita at Georgia Tech, as well as President of Climate Forecast Applications Network, or CFAN, an organization she founded in 2006.

Don J. Easterbrook is Professor Emeritus of Geology at Western Washington University. He was educated at the University of Washington, where he received a BSc, MSc and a PhD (Geology). His doctoral dissertation was entitled Pleistocene Geology of the Northern Part of the Puget Lowland, Washington. Easterbrook has studied global climate change for five decades. He was chairman of the Geology Department at Western Washington University for 12 years. He is an active environmentalist, having initiated undergraduate and graduate programs in environmental geology at Western Washington University.

Here is a compilation from several interviews and lectures by various scientists



Professor Lindzen is a dynamical meteorologist with interests in the broad topics of climate, planetary waves, monsoon meteorology, planetary atmospheres, and hydrodynamic instability. His research involves studies of the role of the tropics in mid-latitude weather and global heat transport, the moisture budget and its role in global change, the origins of ice ages, seasonal effects in atmospheric transport, stratospheric waves, and the observational determination of climate sensitivity. He has made major contributions to the development of the current theory for the Hadley Circulation, which dominates the atmospheric transport of heat and momentum from the tropics to higher latitudes, and has advanced the understanding of the role of small scale gravity waves in producing the reversal of global temperature gradients at the mesopause, and provided accepted explanations for atmospheric tides and the quasi-biennial oscillation of the tropical stratosphere. He pioneered the study of how ozone photochemistry, radiative transfer, and dynamics interact with each other. He is currently studying what determines the pole-to-equator temperature difference, the nonlinear equilibration of baroclinic instability, and the contribution of such instabilities to global heat transport. He has also been developing a new approach to air-sea interaction in the tropics, and is actively involved in parameterizing the role of cumulus convection in heating and drying the atmosphere and in generating upper level cirrus clouds. He has developed models for the Earth’s climate with specific concern for the stability of the ice caps, the sensitivity to increases in CO2, the origin of the 100,000-year cycle in glaciation, and the maintenance of regional variations in climate. Prof. Lindzen is a recipient of the AMS’s Meisinger and Charney Awards, the AGU’s Macelwane Medal, and the Leo Huss Walin Prize. He is a member of the National Academy of Sciences and the Norwegian Academy of Sciences and Letters, and a fellow of the American Academy of Arts and Sciences, the American Association for the Advancement of Sciences, the American Geophysical Union, and the American Meteorological Society. He is a corresponding member of the NAS Committee on Human Rights, and has been a member of the NRC Board on Atmospheric Sciences and Climate and the Council of the AMS. He has also been a consultant to the Global Modeling and Simulation Group at NASA’s Goddard Space Flight Center, and a Distinguished Visiting Scientist at California Institute of Technology’s Jet Propulsion Laboratory. He earned a Ph.D. at Harvard University.

This is an interesting but much “heavier going” lecture. It also includes examples of how scientists get frightened to speak out.  Watch if you have the time and interest.




Giant Of Geology/Glaciology, Prof. Christian Schlüchter, Refutes CO2 …
Feature Interview Throws Climate Science Into Disarray  –  (see his presentation below)

By P Gosselin  9. June 2014

This post is about an interview by the online Swiss Der Bund with Swiss geology giant Christian Schlüchter titled: “Our society is fundamentally dishonest“. In it he criticizes climate science for its extreme tunnel vision and political contamination.

Geologist Sebastain Lüning sent me an e-mail where he writes: “This is probably the best interview from a geologist on climate change that I have read for a long while. My highest respect for Prof. Schlüchter.” Fritz Vahrenholt calls it “impressive”.

(Hat-tip: Bernd Felsche and Wolfgang Neumann at Facebook.)

His discovery of 4000-year old chunks of wood at the edge of glaciers in Switzerland in the 1990s unintentionally thrust the distinguished geologist into the lion’s den of climate science. Today the retired professor and author of more than 250 papers speaks up in an interview.

Almost glacier-free Alps 2000 years ago

Early in the interview Schlüchter reminds us that during Roman times in the Alps “the forest line was much higher than it is today; there were hardly any glaciers. Nowhere in the detailed travel accounts from Roman times are glaciers mentioned.” He criticizes today’s climate scientists for focusing on a time period that is “indeed much too short“.

In the interview, Schlüchter recounts how he in the 1990s found a large chunk of wood near the leading edge of a glacier. The chunk of wood, he describes, looked as if it had been dragged across a cheese shredder. It was clear to Schlüchter that the specimen had to be very old. Indeed laboratory analysis revealed that it was 4000 years old. Next they found multiple wood fragments with the same age, all serving to fill in a major piece of the paleo-puzzle. His conclusion: Today where one finds the Lower Aare-Glacier in the Bernese Alps, it used to be “a wide landscape with a wildly flowing river“. It was warmer back then.

Until the 1990s, scientists thought that the Alps glaciers had been more or less consistently intact and only began retreating after the end of the Little Ice Age. Schlüchter’s findings showed that glacial retreats of the past also had been profound.

This threw climate science into chaos and it remains unreconciled today.

Ice-free 5800 of the last 10,000 years

But not all scientists were thrilled or fascinated by Schlüchter’s impressive discoveries. He quickly found himself the target of scorn. Swiss climate scientist Heinz Wanner was reluctant to concede Schlüchter’s findings. Schlüchter tells Der Bund:

I wasn’t supposed to find that chunk of wood because I didn’t belong to the close-knit circle of Holocene and climate researchers. My findings thus caught many experts off guard: Now an ‘amateur’ had found something that the Holocene and climate experts should have found.”

Schlüchter tells of other works, which also have proven to be a thorn to mainstream climate science, involving the Rhone glacier.

His studies and analyses of oxygen isotopes unequivocally reveal that indeed “the rock surface had been ice-free 5800 of the last 10,000 years”.

Distinct solar imprint on climate

What’s more worrisome, Schlüchter’s findings show that cold periods can strike very rapidly. Near the edge of Mont Miné Glacier his team found huge tree trunks and discovered that they all had died in just a single year. The scientists were stunned.

The year of death could be determined to be exactly 8195 years before present. The oxygen isotopes in the Greenland ice show there was a marked cooling around 8200.”

That finding, Schlüchter states, confirmed that the sun is the main driver in climate change.

Today’s “rapid” changes are nothing new

In the interview he casts doubt on the UN projection that the Alps will be almost glacier-free by 2100, reminding us that “the system is extremely dynamic and doesn’t function linearly” and that “extreme, sudden changes have clearly been seen in the past“. History’s record is unequivocal on this.

Schlüchter also doesn’t view today’s climate warming as anything unusual, and poses a number of unanswered questions:

Why did the glaciers retreat in the middle of the 19th century, although the large CO2 increase in the atmosphere came later? Why did the earth ‘tip’ in such a short time into a warming phase? Why did glaciers again advance in 1880s, 1920s and 1980s? […] Sooner or later climate science will have to answer the question why the retreat of the glacier at the end of the Little Ice Age around 1850 was so rapid.”

On science: “Our society is fundamentally dishonest”

CO2 fails to answer many open questions. Already we get the sense that hockey stick climate claims are turning out to be rather sorrowful and unimaginative wives’ tales. He summarizes on the refusal to acknowledge the reality of our past: “Our society in fundamentally dishonest“.

“Helping hands for politicians”

In Der Bund interview Schlüchter describes a meeting in England that turned him off completely. The meeting, to which he was “accidentally” invited, was led by “someone of the East Anglia Climate Center who had come under fire in the wake of the ‘Climategate’ e-mails”:

The leader of the meeting spoke like some kind of Father. He was seated at a table in front of the those gathered and he took messages. He commented on them either benevolently or dismissively. Lastly it was about tips on research funding proposals and where to submit them best. For me it was impressive to see how the leader of the meeting collected and selected information. For me it also gets down to the credibility of science. […] Today many natural scientists are helping hands of politicians, and no longer scientists who occupy themselves with new knowledge and data. And that worries me.”

Schlüchter adds that the reputation of science among young researchers is becoming more damaged the more it surrenders to politics. He indirectly blasts IPCC chief scientist Thomas Stocker:

Inventing the devil was one of man’s greatest inventions ever achieved. You can make a lot of money when you paint him on the wall.”

Northern hemisphere still gripped in ice age mode

Schlüchter also says that the northern hemisphere is still in the ice age mode and that the glaciers during the Roman times were at least 300 to 500 meters higher than today. “The mean temperature was one and half degree Celsius above that of 2005. The current development is nothing new in terms of the earth’s history.”

At the end of the interview Schlüchter says that solar activity is what is sitting at the end of the lever of change, with tectonics and volcanoes chiming in.

Christian Schlüchter is Professor emeritus for Quaternary Geology and Paleoclimatology at the University of Bern in Switzerland. He has authored/co-authored over 250 papers.
