The Belief That CO2 Can Regulate Climate Is “Sheer Absurdity” Says Prominent German Meteorologist


NoTrickZone
P. Gosselin

Meteorologist Klaus-Eckard Puls
Physicist and meteorologist Klaus-Eckart Puls was interviewed by Bettina Hahne-Waldscheck of the Swiss magazine “factum“.

I’ve translated and summarized the interview, paraphrasing for brevity.

factum: You’ve been criticising 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 still feel shame that as a scientist I made presentations of their science without first checking it. The CO2-climate hysteria in Germany is propagated by people who are in it for lots of money, attention and power.

factum: Is there really climate change?

Puls: Climate change is normal. There have always been phases of climate warming, many that even 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.

factum: The IPCC is projecting 0.2°C warming per decade, i.e. 2 to 4°C by the year 2100. What’s your view?

Puls: These are speculative model projections, so-called scenarios – and not 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 prophesy. The entire CO2-debate is nonsense. Even if CO2 were doubled, the temperature would rise only 1°C. 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.

factum: How does sea level rise 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.

factum: 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.

factum: 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.

factum: 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°C per 100 meters. Over the last 100 years it has gotten about 0.75°C warmer and so the temperature boundary has shifted up about 100 meters. But observations tell us that also ice 1000 meters up and higher has melted. Clearly there are other reasons for this, namely soot and dust. But soot and dust do not only have anthropogenic origins; they are also caused by nature via volcanoes, dust storms and wildfires. Advancing and retreating of glaciers have always taken place throughout the Earth’s history. Glaciology studies clearly show that glaciers over the last 10,0000 years were smaller on average than today.

factum: 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% of the Earth’s ice is stored in Antarctica, which is one and half times larger than Europe.

factum: 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% of the entire area of Antarctica, but it is exposed to Southern Hemisphere west wind drift and some of the strongest storms on the planet.

factum: 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 are 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.

factum: 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 1970s, back when all the talk was about “global cooling”. Back then there were breaks with ice chunks hundreds of square kilometres 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.

factum: 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 5000 50 years ago to 25,000 today.

factum: But it is 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 and 1300 Greenland was green on the edges and the Vikings settled there.

factum: 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 swaths 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.

factum: 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.

Frankenstorm


Climate Etc.
Judith Curry

Hurricane Sandy is the largest Atlantic hurricane on record in terms of diameter of the storm. Sandy was associated with an estimated 13 foot storm surge in areas near New York City.

The Wikipedia has a good discussion of the meteorology, preparations, and impacts of Sandy.

CFAN’s forecasts

Sandy was a highly predictable storm. Allow me some bragging rights regarding the forecasts made by my company CFAN (see this post describing our forecast methods).

We began watching the potential for disturbance in the Caribbean on 10/12, and on 10/16 we forecast a 40% of forming a TC and on 10/19 we predicted a high probability of formation. On 10/23, the NHC named Sandy as a tropical storm. CFAN’s forecast on 10/23 predicted a high probability of Sandy becoming a hurricane, with a 30% probability of landfall on the U.S. northeast coast. On 10/24, we predicted 50% probability of a landfall on the northeast U.S. coast on 10/29 or 10/30, with the most likely location between Delaware and New Jersey. On 10/24 we also forecast a horizontal size of 1250 km and a large storm surge.

Last Friday, CFAN’s lead forecasters conducted a webinar briefing for over 400 people in the energy sector, to help understand and plan for impacts in the energy sector (power outages, energy demand, impacts on northeast refineries).

Global warming (?)

I’m sure you have all spotted articles that blame Hurricane Sandy on AGW. Bill McKibben, in a post on democracynow, sums it up as:

Bill McKibben on Hurricane Sandy and Climate Change: “If There Was Ever a Wake-up Call, This Is It”

In the midst of a lot of unwarranted alarmisn on this issue, I have spotted two articles that, IMO, treat this issue appropriately

NPR

Eric Berger

One of my first blog posts at Climate Etc. was entitled Hurricanes and global warming: 5 years post Katrina. If you missed it the first time, have a look. Heck, even if you’ve read it before, read it again. The science has not changed, my assessment still stands.

The only possible impact of global warming that I am seeing on the Atlantic hurricanes is the extension of the tropical Atlantic warm pool eastward (towards Africa), which means formation is occurring further east than previously and results in more TCs curving North into the Atlantic (so called fish storms). Note: the impact of warming on hurricane intensity seems theoretically robust, but impossible to sort out an AGW signal from the the natural variability.

Kevin Trenberth frequently says that global warming is affecting all of weather. He is probably right, but apart from the relative magnitude of the effect, this begs the question as to whether the effect is good or bad; arguably in terms of Atlantic hurricanes, the warming is resulting in fewer U.S. landfalls.

2012 hurricane season

So far, the 2012 Atlantic hurricane season has seen 19 named storms, 10 hurricanes, and 1 major hurricanes, currently tied with 1887, 1995, 2010, and 2011 as the 3rd most active season for which we have records. At the beginning of the hurricane season, I had a post entitled 2012 Atlantic Hurricane Season. Pretty much everyone was predicting below normal activity; revisions on Aug 1 raised the levels to closer to normal activity. Note: I do not make seasonal hurricane forecasts myself.

What happened? A big part of the failed seasonal hurricane forecasts is ENSO. From my post:

Bottom line ENSO forecast: many forecasters think we are headed for El Nino by late summer/autumn. I agree that the most likely scenario is to have the ENSO index positive, it is not clear whether it will stay in neutral territory or make it to El Nino. Note: there is no sign of a Modoki (central Pacific warming), which is more predictable than ENSO.

In an ENSO neutral year, the AMO and PDO have substantial control. At the beginning of the summer:

With regards to AMO and PDO, the AMO index is currently moderately positive, the PDO index is currently moderately negative.

In this regime (which characterized the 1950’s), there were a large number of U.S. landfalls, particularly on the Atlantic coast.

Sandy impacts

At the time I am writing this, 16 people have been killed and the early estimates of insured damage are $10-$20B. Given the magnitude of this storm, size of population impacted and concentration of property in the path of the storm, these numbers are really astonishing low. The forecast for this storm was spot on, and the NHC pretty much had it right about 5 days in advance. FEMA and other agencies were on this very early in the game. Mayors of cities were primed for effective action after Hurricane Irene. NCY Mayor Bloomberg has done an exceptional job in this regard.

Sandy is a terrific example of how the U.S. is adapting to the elevated hurricane activity. Hurricane Katrina was a huge wake up call. A key element of this adaptation is good weather forecasts. Another key element is good partnership between the forecasters and decision makers. It is reassuring to see this success, particularly in view of the issues surrounding the Italian seismologists.
