10 to 1 odds for Prof. David Barber

August 27, 2014

Background

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.

Climate Hockey Stick Confirmed!!

June 29, 2014

The Climate deniers are taking it on the chin again today as another independent source confirms the climate hockey stick that was first revealed by Michael Mann.  It is getting harder and harder for those corporate sponsored capitalist luddites to hide the truth about runaway effects of increasing atmospheric CO2.

See for yourself…

graph 140629_2

 

This satellite data comes to us via an unimpeachable source: The University of Illinois Department of Atmospheric Sciences. What could be clearer than the rapidly rising temperature seen in the blade of the hockey stick on the right side of the graph? Based on this data, it is high time that the deniers are rounded up and punished (executed?) for their greed inspired destruction of the planet.

The Search for Acceleration, part 10, US Gulf Coast

February 17, 2014

magnifying glass 145This is part 9 of a series of posts in which I am searching for a large acceleration in sea level rise rate in the latter part of the 20th century.  Such a rise rate is needed  to reconcile the 1.8 mm per year average rise rate for the century attributed to tide gauge data and the approximately 3 mm per year rise rate for the tail end of the century attributed to the satellite data.

U.S. Gulf Coast

This region  has 4 tide gauge sites with at least 90% data completion between 1950 and 2008.  Three of the sites have data back to 1930 or earlier .  I will analyse this data in my usual manner: detrending, weighting, averaging and derivatives.

This slideshow shows my standard analysis.

Conclusion

One thing is certain from the above graphs: the sea level rise rate in the US Gulf Coast region has not shown an acceleration in the last part of the 20th century or the 21st century. The rise rate reached a peak in the 1940s and has been dropping since around 1970.

Keep in mind that there are many factors that contribute to the rise rate in this region.  Subsidence is the primary cause, and subsidence itself has multiple components.

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

Why left-leaning environmentalists ignore southern peril

January 23, 2014

I have pointed out the imminent danger of global freezing to the Southern Hemisphere.  I have pondered why it is that the left-leaning environmentalist get all worked up about warming in the arctic, but don’t seem to be bothered by rapidly advancing ice in the South.  I am not sure if their prejudices are conscious or subconscious.

I promised that the answer to this question would break the story wide open.  Here it is…

Time to recognize approaching Southern Hemisphere disaster

December 26, 2013

I warned the world before, and they ignored me, but the evidence continues to mount. The Southern Hemisphere, and maybe the entire world, is headed for a frozen doom.

All day long polar orbiting satellites fly over the Antarctic and the surrounding ocean and measure the extent of the sea ice.  The amount of ice waxes and wanes with the seasons, ranging from about 2 to 16 million square kilometers between southern summer and winter.

Thirty years of this satellite data have made it possible to calculate the average ice extent for any given day of the year.  The deviation from this average is called the “anomaly.”  It is this anomaly data that reveals the impending drastic changes in the Southern Hemisphere.

Here is the anomaly data for the last three years from the University of Illinois’ Polar Research Group…

advance rate

The anomaly is increasing by half a million extra square kilometers every year!!! To put this in perspective, the Earth has a surface area of about 500 million square kilometers. Roughly speaking, an additional 1/1000th of the Earth’s surface is covered by ice each year. Consider that the Southern Hemisphere sea ice maxes out at about 16 million square kilometers each year, then 32 years of the current increase rate would double this amount.

By 2050, a mere 36 years from now, the ice encased Tierra Del Fuego on the southern tip of South America will replace Greenland as the most ironically named place on Earth.  By 2100 the dairy farms surrounding the town of Gore in the Southern Plains of the South Island of New Zealand will be a frozen mockery to the same-named purveyor of global warming alarmism.

Here is what is in store for the Southern Hemisphere…

You can’t deny this.  This is science!  My conclusion is based on the proven analysis techniques of NASA climate scientist Jay Zwally.

Has the 21st century brought us to a tipping point?

All the best data indicates that a tipping point has already occurred.  Think about this: according to NOAA data (see here and here) 8 out of 10 years with greatest Southern Hemisphere sea ice extent have occurred since 2000!  Here they are in order…

  1. 9/14/13
  2. 9/24/12
  3. 9/24/06
  4. 9/24/09
  5. 9/29/05
  6. 9/28/00
  7. 9/8/04
  8. 9/29/07

We also now know that the all time low temperature for the Antarctic was reached in 2010.  Satellite data shows that on August 10th, 2010, the Antarctic temperature descended to 136 ºF (minus 93 ºC).  This shattered the previous record of minus 128.6 ºF (minus 89.2 ºC), set in 1983.

That is a drop in the minimum recorded temperature of 7.4 ºF in a mere 27 years.  If that continues, as indicated by Jay Zwally type analysis, then the low temperature by 2100 could be minus 159 ºF (minus 106 ºC)!!!

The effects are already being felt

It is now the warm season in the Southern Hemisphere.  Sea ice is making its seasonal retreat, yet the Russian cruise ship, Akademik Shokalskiy, is trapped in the sea ice with “52 tourists, scientists and explorers” and a crew of 22.  You would think the combined brains of all those scientists on board would have kept them out of the zone of freezing water.  While the ship’s brochure points out that “Views are excellent from the large, open decks and the Navigation Bridge'” maybe they couldn’t see the ice coming from the vantage point of the “Lounge and bar, open late afternoon and evening with a wide selection of wines and spirits” (an essential feature of all scientific research vessels).  Our prayers go out to the scientists and others on this harrowing adventure as ice breakers race to free them the frozen grip of the sea.  I hope the sauna stays warm and the booze holds out until they get there.

Why the great silence?

Where are the voices of leading scientists and environmentalists?  Why haven’t you seen anything about this impeding hemispheric disaster on the front pages of the news papers or on prime-time news reports?  A subsequent post will soon answer those questions and break this issue wide open.  

Stay tuned…

James Delingpole, please correct this mistake

November 23, 2013

The only thing that bugs me more than when climate alarmists get things wrong is when skeptics get it wrong.

A case in point is the assertion by James Delingpole that a recent volcano in Iceland put more CO2 into the atmosphere that all of human activity since 1950.

Delingpole is a vocal supporter of the skeptic community, and the fact the he has a widely viewed blog , writes for several publications and authored several books, all give his words wide dissemination.  The problem is that when a fence-sitter who is trying to make up his mind about the global warming issue realizes that somebody like Delingpole is asserting and defending an indefensible claim, well, that fence-sitter is likely to fall off the fence to the side of the alarmists.  This will happen even if Delingpole is correct on other points.  Fence-sitters don’t necessarily have the time or inclination to sort out and weigh all the arguments, and something like this can easily tip their judgement scales one way or the other.

Delingpole appeared as a guest on the Mike Rosen Show on Denver’s AM station KOA.  This is a 50,000 Watt station and tens of thousands of people probably heard this exchange.  Rosen is a pretty smart guy and usually nobody’s fool, but he let this bogus assertion slide by…

Audio version: Rosen/Delingpole 11/20/13 MP3

Rosen: 713-8585 our telephone number in Castle Rock. Cliff, you’re on 850 KOA. James Delingpole our guest. Hi Cliff.

Cliff: Mike and James, good morning.

Rosen: Morning

Delingpole: Hi Cliff.

Cliff: Hey, I finally think I have somebody who can actually answer this question.

Rosen: Alright.

Cliff: Ah, you know we’ve got, the greenies are all against cars and the exhaust, and you know, all this pollution that we put in the air. Ah, whats the equivalency of a volcano that’s erupting and spewing stuff into the air thirty miles high.

Delingpole: That’s a good question. You remember that volcano that erupted in Iceland a couple of years ago?

Cliff: Yep, that’s the one that made me start thinking about it

Delingpole: Yeah, I think that, I think that that – that volcano produced more CO2 than I think humans have produced in the last, in the last fifty years.

Cliff: Watta we gonna do about that? (…unintelligible…)

Delingpole: We should ban volcanoes.

You  can hear the entire interview (Wednesday, 10AM, 11/20/13) on KOA’s podcast

What are the facts?

The facts are well know, easily accessible, and have been presented to Delingpole before now.  Here it is summed up by the USGS…

Do the Earth’s volcanoes emit more CO2 than human activities? Research findings indicate that the answer to this frequently asked question is a clear and unequivocal, “No.” Human activities, responsible for a projected 35 billion metric tons (gigatons) of CO2 emissions in 2010 (Friedlingstein et al., 2010), release an amount of CO2 that dwarfs the annual CO2 emissions of all the world’s degassing subaerial and submarine volcanoes (Gerlach, 2011).

The published estimates of the global CO2 emission rate for all degassing subaerial (on land) and submarine volcanoes lie in a range from 0.13 gigaton to 0.44 gigaton per year (Gerlach, 1991; Varekamp et al., 1992; Allard, 1992; Sano and Williams, 1996; Marty and Tolstikhin, 1998). The preferred global estimates of the authors of these studies range from about 0.15 to 0.26 gigaton per year. The 35-gigaton projected anthropogenic CO2 emission for 2010 is about 80 to 270 times larger than the respective maximum and minimum annual global volcanic CO2 emission estimates. It is 135 times larger than the highest preferred global volcanic CO2 estimate of 0.26 gigaton per year (Marty and Tolstikhin, 1998). 

It is an embarrassment to me, as a skeptic, that the alarmist site “Skeptical Science” gets it right while Delingpole, a well know mouthpiece for skepticism, gets it wildly wrong.  This meme has been around for years and was long ago thoroughly debunked.  

I would forgive an acquaintance at a coffee shop or around the water cooler for making this mistake.  Then I would gently try to set him straight with the facts  But if you are going to put yourself forth as some kind of expert, then you need to get your facts straight.  This type of mistake may win converts to your side in the short run, but when people realize how wrong you have were, then they will not believe you even when you are right.  Worse yet, they will also be less inclined to believe other skeptics when they are right.

So, James, please fess up on this issue.  Admitting this mistake will only improve your credibility in the long run.

By the way, this reminds me of another misinformed claim:that underwater volcanoes in the Gakkel ridge were causing reduced sea ice in the Arctic.
