Consider this admission on 12 May 2012 by the prominent German meteorologist Klaus Eckart Puls in an interview by Bettina Hahne-Waldscheck of the Swiss magazine “Factum”, translated, summarized and paraphrased for brevity by P. Gosselin in a journal article titled “The Belief That CO2 Can Regulate Climate Is Sheer Absurdity”:
Bettina: You’ve been criticizing the theory of man-made global warming for years. How did you become skeptical?
Puls: Ten years ago I simply parroted what the IPCC told us. One day I started checking the facts and data — first I started with a sense of doubt but then I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts and measurements. To this day I feel shame that as a scientist I made presentations of their science without first checking it . . . Scientifically it is sheer absurdity to think we can get a nice climate by turning a CO2 adjustment knob.
Bettina: Is there really climate change?
Puls: Climate change is normal. There have always been phases of global warming, many that far exceeded the extent we see today. But there hasn’t been any warming since 1998. In fact the IPCC suppliers of data even show a slight cooling.
Bettina: The IPCC is projecting 0.2 degrees Celsius warming per decade, i.e., 2 to 4 degrees Celsius by the year 2100. What’s your view?
Puls: These are speculative model projections, so-called scenarios — and no
prognoses. Because of climate’s high complexity, reliable prognoses just aren’t possible. Nature does what it wants, and not what the models present as prophecy.
The entire CO2 debate is nonsense. Even if CO2 were doubled, the temperature would rise only 1 degree Celsius. The remainder of the IPCC’s assumed warming is based purely on speculative amplification mechanisms. Even though CO2 has risen, there has been no warming in 13 years.
Bettina: How does sea level look?
Puls: Sea level rise has slowed down. Moreover, it has dropped a half centimeter over the last 2 years. It’s important to remember that mean sea level is a calculated magnitude, and not a measured one. There are a great number of factors that influence sea level, e.g., tectonic processes, continental shifting, wind currents, passats, volcanoes. Climate change is only one of ten factors.
Bettina: What Have we measured at the North Sea?
Puls: In the last 400 years, sea level at the North Sea coast has risen about 1.40 meters. That’s about 35 centimeters per century. In the last 100 years, the North Sea has risen only 25 centimeters.
Bettina: Does the sea level rise have anything to do with the melting North Pole?
Puls: That’s a misleading conclusion. Even if the entire North Pole melted, there would be no sea level rise because of the principles of buoyancy.
Bettina: Is the melting of the glaciers in the Alps caused by global warming?
Puls: There are many factors at play. As one climbs a mountain, the temperature drops about 0.65 degrees Celsius per 100 meters. Over the last 100 years it has gotten about 0.75 degrees Celsius warmer and so the temperature boundary has shifted up about 100 meters. But observations tell us that ice also 1,000 meters up and higher has melted. Clearly there are other reasons for this, namely soot and dust. But soot and dust do not have only anthropogenic origins; they are also caused by nature via volcanoes, dust storms, and wildfires. Advances and retreats of glaciers have always taken place throughout the Earth’s history. Glaciology studies clearly show that glaciers over the last 10,000 years were smaller on average than today.
Bettina: In your view, melting Antarctic sea ice and the fracture of a huge iceberg 3 years ago are nothing to worry about?
Puls: To the contrary, the Antarctic ice cap has grown both in area and volume over the last 30 years, and temperature has declined. This 30-year trend is clear to see. The Amundsen Scott Station of the USA shows that temperature has been declining there since 1957. 90 percent of the Earth’s ice is stored in Antarctica, which is one and a half times larger than Europe.
Bettina: Then why do we always read it is getting warmer down there?
Puls: Here they are only talking about the West Antarctic peninsula, which is where the big chunk of ice broke off in 2008 — from the Wilkins-Shelf. This area is hardly 1 percent of the entire area of Antarctica, but it is exposed to Southern Hemisphere west wind drift and some of the strongest storms of the planet.
Bettina: What causes such massive chunks of ice to break off?
Puls: There are lots of factors, among them the intensity of the west wind fluctuations. These west winds have intensified over the last 20 years as part of natural ocean and atmospheric cycles, and so it has gotten warmer on the west coast of the Antarctic peninsula. A second factor is the larger waves associated with the stronger storms. The waves are more powerful and so they break off more ice. All these causes are meteorological and physical, and have nothing to do with a climate catastrophe.
Bettina: Then such ice breaks had to have occurred in the past too?
Puls: This has been going on for thousands of years, also in the 1970’s back when all the talk was about “global cooling”. Back then there were breaks with ice chunks hundreds of square kilometers in area. People were even discussing the possibilities of towing these huge ice chunks to dry countries like South Africa or Namibia in order to use them as a drinking water supply.
Bettina: What about all the media photos of polar bears losing their ice?
Puls: That is one of the worst myths used for generating climate hysteria. Polar bears don’t eat ice, they eat seals. Polar bears go hungry if we shoot their food supply of seals. The polar bear population has increased with moderately rising temperatures, from 5,000 50 years ago to 25,000 today.
Bettina: But is it true that unlike Antarctica, the Arctic is melting?
Puls: It has been melting for 30 years. That also happened twice already in the last 150 years. The low point was reached in 2007 and the ice has since begun to recover. There have always been phases of Arctic melting. Between 900 AD and 1300 AD Greenland was green on the edges and the Vikings settled there.
Bettina: And what do you say about the alleged expanding deserts?
Puls: That doesn’t exist. For example, the Sahara is shrinking and has lost in the north an area as large as Germany over the last 20 years. The same is true in the South Sahara. The famine that struck Somalia, Kenya and Ethiopia was mainly caused by the leasing of large swathes of land to large international corporations so that they could grow crops for biofuels for Europe, and by war. But it is much easier for prosperous Europe to blame the world’s political failures on a fictional climate catastrophe instead.
Bettina: So we don’t need to do anything against climate change?
Puls: There’s nothing we can do to stop it. Scientifically, it is sheer absurdity to think we can get a nice climate by turning a CO2 adjustment knob. Many confuse environmental protection with climate protection. It’s impossible to protect the climate but we can protect the environment and our drinking water. On the debate concerning alternative energies, which is sensible, it is often driven by the irrational climate debate. One has nothing to do with the other.

The war on hydro-carbon fuels will have no measurable effect on global temperatures. Nor will carbon taxes, carbon offsets or subsidies for wind turbines or solar panels. There are climate controllers far bigger than human CO2 at work.
No place on Earth lives in the mythical average global temperature. Earth’s temperature dances to cyclic rhythms every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles.
The daily cycle of Earth’s rotation causes continual changes in radiant energy received by and transmitted from every spot on Earth. It produces the cold at dawn and the afternoon warmth.
Superimposed on the daily solar cycle is the monthly lunar cycle, driven by the orbit of the Moon around the Earth. These two cycles interact to produce variations in atmospheric pressure, and tides and currents in the oceans and the atmosphere. These are the short-term weather makers.
The yearly seasonal cycle is caused as the tilted axis of Earth’s rotation affects the intensity of solar energy received by each hemisphere. This produces spring, summer, autumn and winter for every spot on Earth. As the Earth’s orbit cycles between more or less elliptical, seasonal extreme temperatures also vary.
Then there is the 22 year sun-spot cycle, which correlates with cycles of floods and droughts. Sunspots are indicators of solar activity which cause periods of global warming and cooling.
Earth also generates the less predictable El Nino climate events that have a huge effect on the global patterns of weather and temperature.
The least recognised but most dangerous climate cycle is the glacial cycle.
We live in the Holocene Epoch, the latest warm phase of the Pleistocene Ice Age. The climate history of the Holocene, and its predecessor the Eemian, are well documented in the ice core logs and other geological records. One cycle consists of a glacial age of about 80,000 years followed by a warmer age of about 20,000 years, with peak warming occurring over about 12,000 years. Our modern warm era commenced 12,000 years ago, so it is probably nearing its end.
There have been eight warm eras separated by long glacial winters over the last 800,000 years of the Pleistocene. In every beat of this cycle, the vast ice sheets melt, sea levels rise dramatically, coral reefs and coastal settlements are drowned, and forests and animals re-colonise the higher land released from the ice. Warm climate animals such as hippos, water buffaloes and elephants got as far north as Germany in the last warm era.
Then the ice returned, covering the northern hemisphere as far south as Chicago and London, destroying the forests, lowering the seas, stranding the relocated coral reefs and eliminating unprepared species. (Some dopey grizzly bears got stranded in the growing Arctic Ice and the most enterprising of them survived to evolve into white grizzlies now called polar bears.)
This regular repetition of natural climate change is best explained by the Milankovitch cycles relating to changes in Earth’s orbit and tilt. These drive variations in solar energy received by Earth and have the greatest temperature effect on the large land masses of the Northern Hemisphere.
Earth’s climate is never still for long.
On a longer time scale, passage of the solar system through the plane of the Galaxy seems to trigger magnetic reversals and violent spasms of volcanism, glaciation and species extinction.
What is the role of carbon dioxide in climate? Al Gore did a great job to dramatise the recurring cycles of glaciation and carbon dioxide in his widely acclaimed work of science fiction. But he missed two “inconvenient truths”.
First, the ice cores show that in the glacial spring-time the temperature rose BEFORE the CO2 levels rose. Therefore the rising CO2 cannot be a CAUSE of the warming – it is a RESULT of CO2 being expelled from the warming oceans.
Second, at the top of every summer-time in the glacial cycle, the high levels of CO2 in the atmosphere were totally unable to prevent the cooling into the next cycle of ice. CO2 levels fell later as the cooling oceans absorbed more CO2.
We are already in the autumn of the current glacial cycle and nothing man can do will change that. Global temperatures today are lower than they were in Roman and Medieval times. They will still fluctuate with the effects of daily, lunar, seasonal, yearly and sun-spot cycles, but the long-term trend of maximum and minimum temperatures will continue drifting downwards. As soon as summer temperatures in Siberia and northern Canada are unable to melt last winter’s snow, the growing glaciers will join to form ice sheets which reflect more solar radiation, and Earth will once again slip into another long hungry Glacial Winter.
The warm days, seasons, years and epochs have never been a deadly threat to life on Earth. Frost, snow, hail and ice are the killers. If our descendants do not have the energy, resources and wisdom to keep their people warm and fed through the coming glacial epoch, humans may follow our Neanderthal cousins who perished in the last glacial winter, just 20,000 years ago.
There is ZERO evidence in the climate record that carbon dioxide has a detectable effect on global temperatures. However if it does indeed slightly delay the onset of the next glacial winter, we and all life on Earth should count ourselves extremely lucky.

Earth is a dangerous place. Of all the species that have ever lived, over 95% have already been extinguished by natural disasters.
Ice, not global warming, is the big killer and this recurring calamity often strikes quickly. Thousands of mammoths and other animals were killed by ice storms and their snap-frozen bodies are still entombed in ice around the Arctic. Just 15,000 years ago great ice sheets smothered the northern hemisphere as far south as Chicago, Moscow and London and all life had migrated towards the equator. This deadly ice had gripped Earth for about 50,000 years.
Ice ages are also times of dry winds and drought as cold oceans and cold dry atmospheres produce little evaporation or precipitation. Great deserts like the Sahara and the Gobi expand, and wind-blown dust fills the skies and rivers.
Adding to Ice Age woes, cold oceans suck the gas of life (carbon dioxide) out of the atmosphere, thus making surviving plants less able to cope with cold and drought. One of the great serendipities of modern life is that man’s use of carbon-rich fuels like oil and coal not only provides energy but also adds carbon dioxide plant food to the severely depleted carbon stocks of the atmosphere. Satellites have detected the resultant greening of the Earth.
Earth also suffers cycles of volcanism where much life is extinguished by ash, lava, earthquakes and tsunamis, usually followed by more cold and starvation as dust blocks sunlight. Just one era of volcanism covered the Deccan in India with many lava flows in places more than 2 km thick and spewed hot lava into the oceans along the mid-ocean trenches. Earthquakes and resulting tsunamis swept all life from large areas of land and dumped and buried their fragmented remains in heaps of mud.
We also have evidence of massive destruction on Earth from collisions and near misses by comets and other bodies in the solar system.
Humans are not immune to the threat of extinction, but it will not come from today’s warm, moist, atmosphere or from the gas of life, carbon dioxide. It will probably come from the next glacial cycle in the Pleistocene Ice age, where long bitter glacial eras are separated by short warm periods such as the Holocene warm era in which we live.
In every short warm era like today’s Holocene, the warming oceans expel enough carbon dioxide into the atmosphere to terrify today’s global warming alarmists. And these times have always supported abundant plant and animal life. But never has “global warming” from this “greenhouse gas” prevented the cyclic return of the ice.
When blizzards blow and glaciers grow, the great ice sheets will spread again and mankind will be decimated by cold, drought, crop failures and starvation. A lucky few living in equatorial regions or clustered in shelters and hot houses around nuclear power stations will survive. Those still able to extract coal, oil or gas may manage to generate enough warmth and carbon dioxide plant food to offset the cold sun, the perma-frost and the barren atmosphere. And a few with appropriate skills and tools may become hunters and gatherers again (but the Neanderthals did not make it last time).
We should celebrate, not fear, the Modern Warm Era and give thanks for the many benefits gained from recycling those marvellous batteries of stored and buried carbon resources to our still-hungry biosphere.
When the ice returns, derelict and snow-bound wind turbines and solar panels will remain as stark evidence of the failed Green religion of yet another endangered species.
