Barack Obama: Glaciologist

September 6, 2015

The avid outdoors-man and eminent scientist, Barack Obama, has been trekking through Alaska lately.  He is lamenting the demise of the great glaciers of the North.  He is surely grieving over the harm that man is inflicting on the planet by spewing his toxic CO2.  The Washington Post reports

Standing near the foot of the Exit Glacier, which has receded 1.25 miles since 1815 and 187 feet last year alone, Obama said “this is as good of a signpost of what we’re dealing with it comes to climate change as just about anything.”

The man certainly has a way with words – a true poet.

I guess we are supposed to be alarmed because 187 feet per year is a lot faster than 1.25 miles per 200 years.  After all, 1.25 miles in 200 years averages out to only 33 feet per year.  The message we are supposed to get is that the Exit Glacier is receding about 6 times faster now than its average over the last 200 years.  This, of course, is due to the CO2 that vile humans use to poison the atmosphere and it means endless and escalating disaster unless we socialize the economy of the world.

But what does the National Park service say about the retreat rate of Exit Glacier? The following table of retreat distances and rates comes from the National Park Service’s “The Retreat of Exit Glacier.” Annotation in red was added by me.

Exit glacier retreat annotatedSo, this data confirms Obama’s assertion that the Exit Glacier has retreated 1.25 miles in the last 200 years.  But it also makes it quite clear that it was retreating as fast, or faster, 100 years ago.

If CO2 is the culprit today, what was the culprit 100 years ago?  The following graph shows the amount of anthropogenic CO2 in the atmosphere as a function of time going back to 1750.  The data comes from Oak Ridge National Laboratory.  I made the plot and added the annotation. It’s kind of hard to explain why the retreat rate was so much greater in the past when there was less than 10% of the anthropogenic atmospheric CO2 than there is today.  Perhaps Professor Obama will elucidate.

anthro atmos carbonMy wife and I were up in Alaska a few years ago, and we also visited some some of those receding glaciers.  At Glacier Bay National Park, which is several hundred miles southeast of Exit Glacier, I happened to pick up a park pamphlet that had the following series of illustrations showing the glacier extents in the park going back to 1680.

glacier bay extents v3The first thing that jumps out at you is the rapid ice advance between 1680 and 1750 and the subsequent retreat between 1750 and 1880.  The pamphlet said

“The Little Ice Age came and went quickly by geologic measures.  By 1750 the glacier reached its maximum, jutting into Icy Strait.  But when Capt. George Vancouver sailed here 45 years later, the glacier had melted back five miles into Glacier Bay – which it had gouged out.”

As an aside, a co-worker once told me that the Little Ice Age was not a global phenomenon, but rather, local to Europe.  He cited the Union of Concerned Scientists as the source of this insight.  But there it is, in Alaska!

It is hard to argue with the Union of Concerned Scientists because they’re, well, scientists.  Not just anybody can be a Concerned Scientist.  You have to send a check first.  My wife used to send a check years ago, but it was from our joint account so I figure I was only half a Concerned Scientist then.  Now I guess I am just a wholly unconcerned scientist.

IMG_1546 v2Anyway, Obama was getting excited about 1.25 miles of glacier recession since 1815, and a whopping 187 feet in the last year.  That pamphlet that I mentioned also had a large map of the Glacier Bay area marking the location of the various glaciers back to 1760. It’s easy to string the locations together and calculate the recession rate of these glaciers.  The image at the left  shows the map as I marked it out for Grand Pacific Glacier. (Click to enlarge.)

I have plotted the distance as a function of time for three glacier routes using this crude method.   As you can see below, these glaciers have receded at a much faster rate than Exit Glacier.  But Exit Glacier and the Glacier Bay National Park glaciers have one thing common:  they all retreated at their maximum rate back when anthropogenic atmospheric CO2 levels were very low compared to today.

Glacier retreatLet’s take a closer look at the Grand Pacific Glacier.  John J. Clague and S. G. Evans (J. of Glaciology)  used various data sources to plot the retreat of the Grand Pacific Glacier.  I have converted their data to miles and overlaid it with my coarser data from the map. The Clague data and the map data agree nicely, but the Clague data fills in some of the gaps.  The most interesting point is that like Exit Glacier, the retreat rate for the Grand Pacific Glacier was greatest around the last part of the 19th century. In fact, the Clague data may indicate that the Grand Pacific Glacier was slightly progressing, not retreating, during most of the 20th century.

Grand Pacific Glacier retreatIt is pretty clear that the Grand Pacific Glacier was retreating fastest around 1860.  Where is that on the anthropogenic atmospheric CO2 timeline?  The graph below shows that the anthropogenic atmospheric CO2 level was only about 2% of today’s level when the Grand Pacific Glacier was retreating at its fastest by far!

CO2 and Grand PacificHow is that possible???????  I thought it was high CO2 levels that caused the glaciers to recede.


Definition: Barber Event

May 9, 2015

A monumental climatic event is unfolding before our eyes this year.  The ramifications will affect entire human race, nay, the entire community of Gaia dwelling souls.

 David Barber, 21st Century Arctic Explorer, has been warning us for years, but too many of us have been blinded by our greed for oil and money.  The Arctic will go completely ice free this summer.  This will no doubt force polar bears into extinction and set off a globe spreading chain reaction of extinction and desolation.

This extraordinary occasion deserves its own geological name.  I propose we call it the “Barber Event.”

Here is what will happen to Arctic sea ice…

Seven IPCC Claims Refuted

December 8, 2014

Roger Andrews addresses seven claims of the IPCC Working Group 2.  I know that oil people are supposed to be automatically suspect, but open your mind and read what Andrews has to say as he handily addresses these points…

Claim 1: Glaciers continue to shrink almost worldwide due to climate change

Claim 2: Many terrestrial, freshwater, and marine species have shifted their geographic ranges ….. in response to ongoing climate change.

Claim 3: While only a few recent species extinctions have been attributed as yet to climate change, natural global climate change at rates slower than current anthropogenic climate change caused significant ecosystem shifts and species extinctions during the past millions of years.

Claim 4: Based on many studies covering a wide range of regions and crops, negative impacts of climate change on crop yields have been more common than positive impacts.

Claim 5: Impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability.

Claim 6: At present the worldwide burden of human ill-health from climate change is relatively small … and is not well quantified. However, there has been increased heat-related mortality and decreased cold-related mortality in some regions as a result of warming.

Claim 7: Violent conflict increases vulnerability to climate change.

Here is a teaser.

Victor Davis Hansen has his say about “climate change”

December 3, 2014

Hansen sums up the phenomena of global warming alarmism in two ripping paragraphs…

Take also global warming — for Secretary of State John Kerry, the world’s greatest challenge. Once the planet did not heat up in the last 18 years, and once the ice of the polar caps did not melt away, global warming begat climate change. The new nomenclature was a clever effort to link all occasional weather extremities to some underlying and fundamental climate disruption. Brilliant though the strategy was — the opposites of cold/hot, drought/deluges, and calm/storms could now all be used as proof of permanent climate change — global warming finally was hoist on its own petard: If it caused everything, then it caused nothing.

So, in the end, what was global warming? It seems to have grown up largely as a late-20th-century critique of global-market capitalism by elites who had done so well by it that they had won the luxury of caricaturing the very source of their privilege. Global warming proved a near secular religion that filled a deep psychological longing for some sort of transcendent meaning among mostly secular Western grandees. In reality, the global-warming creed had scant effect on the lifestyles of the high priests who promulgated it. Al Gore did not cut back on his jet-fueled and lucrative proselytizing. Obama did not become the first president who, on principle, traveled with a reduced and green entourage. Solyndra did not run a model transparent company as proof of the nobility of the cause. As in the case of illegal immigration, the losers from the global-warming fad are the working and middle classes, who do not have the capital to be unharmed by the restrictions on cheap, carbon-based fuels.

Plain Speaking from John Coleman

October 22, 2014

John Coleman, co-founder of the Weather Channel, knows a thing or two about the climate.  He recently had plenty to say about global warming hysteria.  In an open letter to the UCLA Hammer Forum he said…

The ocean is not rising significantly. The polar ice is increasing, not melting away. Polar Bears are increasing in number. Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing). I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid.

Here’s John explaining the basics…



10 to 1 odds for Prof. David Barber

August 27, 2014


Back in 2008 University of Manitoba Professor David Barber made two rediculous statements.  First, National Geographic reported on June 20th, 2008, that Barber said

“We’re actually projecting this year that the North Pole may be free of ice for the first time [in history].”

Of course, that did not happen.  At the low point for the year there were still 3 million square kilometers of ice in the Arctic and 2.25 million square kilometers in the Arctic Basin.   But Barber wasn’t done sharing his insight.   That year the Star Pheonix (Saskatoon) reported

The ice that has covered the Arctic basin for a million years will be gone in little more than six years because of global warming, a University of Manitoba geoscientist said. And David Barber said … he estimates the Arctic sea should see its first ice-free summer around 2015.

At the time I challenged Barber to…

…a friendly wager based on this prediction. I will bet David Barber $1000(US) that the ice covering the Arctic Basin will not be gone anytime before December 31st, 2015. The bet would involve no transfer of cash between myself or Barber, but rather, the loser will pay the sum to a charitable organization designated by the winner.

Definition of terms. The Arctic Basin is defined by the regional map at Cryosphere Today. “Gone” means the Arctic Basin sea ice area is less that 100,000 square kilometers, according to National Center for Environmental Prediction/NOAA as presented at Cryosphere Today . Charitable organizations will be agreed upon at the time the bet is initiated.

David Barber is a smart guy and evidently an expert in his field. Taking on a wager with an amateur like me should be like shooting fish in a barrel. I look forward to reaching an agreement soon.

I got no response from Barber.

On August 15th, 2009, I upped the ante, sending Barber email offering 2 to 1 odds.

Still no response. 

Instead, in November of 2009 The Univeristy of Manitoba published this video of Barber…

Current Ice Status

Anybody who is paying attention knows that Barber has been wildly off the mark for the Arctic, and that the sea ice extent in the Antarctic is pushing record highs.  Globally, the sea ice area has been above its historical average during most of the last year.

10 to 1 odds

Today I am offering Barber 10 to 1 odds.  That’s right, I will put up $10,000 to his $1000 that the ice covering the Arctic Basin will not be gone anytime before December 31st, 2015, all the rest of the terms being the same.  Today I sent Prof. Barber this email, to the address found here.   I am looking forward to hearing from him soon.


Vermeer and Rahmstorf paper rejected

January 31, 2014

Vermeer and Rahmstorf had a paper rejected by the journal “Climate of the Past.” This news is 16 months old, but I just heard about it, and could find very few references about it on the web.

This paper, On the differences between two semi-empirical sea level models for the last two millennia,  promoted their earlier sea level rise models.  They couldn’t seem to get traction with this paper.

Here are some reviewers’ comments…

One of the major problems with this work is the decidedly biased analysis and presentation.

Highly biased analysis and presentation.

It currently takes significant effort to figure out which pairs of models and training data sets the authors use, and whether they have evaluated all the relevant combinations of the same.

No surprise here.  Rahmstorf has a history of alluding to all kinds of data sets and implying that he has taken them into consideration, but only presenting results for those that support his thesis.

And the final blow…

In the light of the two negative reviews and one comment which all require new analyses and point to fundamental flaws in the methodology of the current paper, I regret to inform you that my conclusion is to support rejection. I strongly dissuade the authors from submitting responses and a revised version.

Here is the paper…

Here is the reviewers’ discussion that lead to the the rejection.

Of course, Vermeer and Rahmstorf do not give up that easily, and similar papers have been shopped around to other journals
