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.
A tribute to Al Gore’s Brisbane visit by Viv Forbes
The Priest of Global Warming
Flew in to earn big fees
He warned of heat waves forming
Unless we grew more trees
Alas for Big Al’s forecast
The weather did not warm
Antarctic winds began to blast
And snowy clouds were formed
So if you’re sick of sunshine
And bored with balmy heat
Just pay Big Al to wine and dine
You’ll soon have frost and sleet.
I have spent 55 years in the engineering profession where ignoring the evidence often kills people. Thus I am predisposed to look at the evidence before drawing conclusions.
Many articles and claims about sea levels are in conflict with the evidence.
For instance, sea level has been rising at something between 2 and 3 mm per year since the end of the Little ice age. As you can see from the graph, there is no indication that the rate of sea level rise is increasing. There is some indication that the rate of rise has reduced slightly since 2006.
In addition, the Australian Bureau of Meteorology set up a chain of sea level measuring stations around Australia and in the Pacific that are the most accurate in the world. As you can see from the chart, the sea level at Tuvalu dropped markedly during the 1997 – 1998 El Niño and since 2000 it has been substantially constant. Claims that Tuvalu is sinking beneath rising sea levels caused by man-made carbon dioxide therefore cannot be true. it is most unfortunate that many people who choose to spread this rumour have not bothered to look at the data. It is particularly unfortunate for the population of Tuvalu because they have been told that their very real problems with erosion are beyond their control when, in fact, they have largely caused them by taking too much fresh water out of the water table and by mining the reef for coral to reclaim land. If the powers that be recognised that this is the case, then aid could be concentrated on solving the real problems, not the imaginary ones.
One division is 100 mm.
Others claim that Pacific Islands are disappearing. Once again, this does not stack up against the evidence:
