Barack Obama conceded over the weekend that no successor to the Kyoto Protocol would be signed in Copenhagen next month. With that out of the way, it may be too much to hope that the climate change movement take a moment to reflect on the state of the science that is supposedly driving us toward a carbon-neutral future.

But should a moment for self-reflection arise, campaigners against climate change could do worse than take a look at the work of Stephen McIntyre, who has emerged as one of the climate change gang’s Most Dangerous Apostates. The reason for this distinction? He checked the facts.

The retired Canadian businessman, whose self-described “auditing” a few years ago prompted a Congressional review of climate science, has once again thrown EnviroLand into a tailspin. In September, he revealed that a famous graph using tree rings to show unprecedented 20th century warming relies on thin data. Since its publication in 2000, University of East Anglia professor Keith Briffa’s much-celebrated image has made star appearances everywhere from U.N. policy papers to activists’ posters. Like other so-called “hockey stick” temperature graphs, it’s an easy sell—one look and it seems Gadzooks! We’re burning ourselves up!

“It was the belle of the ball,” Mr. McIntyre told me on a recent phone call from Ontario. “Its dance card was full.”

McIntyre and Lindzen to appear on Finnish TV documentary – transcript

9 11 2009

Transcript in English from the TV network website here (h/t to Goran Frojdh)

MOT: Climate catastrophe cancelled
Finnish Broadcasting Co. YLE, TV1, Nov 11th 2009 at 8.00 pm.

Voiceover (VO), reporter Martti Backman: Governments around the world are preparing for a grand climate conference, which should decide how humanity responds to the threat of a climate catastrophe. Negotiations are under way to replace the Kyoto treaty with a new treaty of Copenhagen.

VO: The threat is based on assessments by the Intergovernmental Panel on Climate Change, the IPCC. According to the panel, the Earth is going through an unprecedented period of temperature increase, caused by man and his carbon dioxide emissions from burning coal and oil.

(Pictures from An Incovenient Truth)

The Earth’s climate has always been changing. But now we are told that warming is happening faster than ever. The view is based on this figure.


(Picture: The global warming hockey stick graph. Music: Electric organ sounds from an ice-hockey game)

VO: This ten-year-old figure, dubbed as the hockey stick, was meant to revolutionize the dominant view of global climate history. The stick’s handle stretches for almost a thousand years, creating an impression of a steady climate, and its’ rising blade in the late 1900’s is proof of sudden, strong warming, which is caused by man.

According to the older view, climate has naturally varied considerably over the past millennium, and in the middle ages it was clearly warmer than today. But in the hockey stick graph, the Medieval Warm Period and the little ice age after it have disappeared. The hockey stick was promoted to honorary status in the IPCC’s third assessment report’s cover. It became the logo of catastrophic climate change. The stick was used to back up the claim that, 1998 was the warmest year of the millennium. Read the rest of this entry »

A real hockey stick

31 10 2009

In the past decade, since the release of the flawed 1998 study by Michael Mann, now known as MBH 98, the phrase “hockey stick” has been used to describe a certain shape of a graph. It has also become synonymous with poor data selection and  bad statistical procedure.

Yet again and again we see climate studies pushing this hockey stick shape as a way of saying we are “living in the worst time period of the data”.

Here, without statistics, without bristlecone pines, inverted lake sediments, midge larvae carcasses, larch trees in Yamal, or convoluted never before seen statistical methods, I present a directly measured data set that produces a real “hockey stick” shape.

Graph: It's worse than we thought

The data is directly measured and not a proxy, the plot is real. There’s no data adjustment or statistical manipulation. Care to know what it is? Read the rest of this entry »

Yamal treering proxy temperature reconstructions don’t match local thermometer records

30 10 2009

Circling Yamal 3 – facing the thermometers

Guest post by Lucy Skywalker

Let’s look closely and compare local thermometer records (GISS) with the Twelve Trees, upon whose treerings depend all the IPCC claims of “unprecedented recent temperature rise”.
For my earlier Yamal work, see here and here. For the original Hockey Stick story, see here and here.

Half the Hockey Stick graphs depend on bristlecone pine temperature proxies, whose worthlessness has already been exposed. They were kept because the other HS graphs, which depend on Briffa’s Yamal larch treering series, could not be disproved. We now find that Briffa calibrated centuries of temperature records on the strength of 12 trees and one rogue outlier in particular. Such a small sample is scandalous; the non-release of this information for 9 years is scandalous; the use of this undisclosed data as crucial evidence for several more official HS graphs is scandalous. And not properly comparing treering evidence with local thermometers is the mother of all scandals.

I checked out the NASA GISS page for all thermometer records in the vicinity of Yamal and the Polar Urals, in “raw”, “combined”, and “homogenized” varieties. Here are their locations (white). The Siberian larch treering samples in question come from Yamal and Taimyr. Salehard and Dudinka have populations of around 20,000; Pecora around 50,000; Surgut around 100,000; all the rest are officially “rural” sites. Some are long records, some are short.

Video: How some skeptics might view the “rush to save the planet now!” meme

14 10 2009

My lovely wife pointed this out to me tonight while I was writing the post on the DMSP/SSMI sea ice sensor issue. It spoke to me, not only because it was hilarious, but because I immediately saw a comparison in it to how I feel (as well as many others) about the “rush” to save the planet. We keep hearing these pronouncements that we only have “X number of years left” to act, that we’ll reach “tipping points”, or “points of no return” if we don’t pass the Copenhagen Treaty.

But while the warmers are driving in the fast lane to Copenhagen, us annoying old skeptics (which is how many warmers view us) keep plodding along with facts (they are stubborn things you know) with occasional whacks to the climate science fast track like McIntyre’s recent revelations about the majority of the hockey stick being based on a few tree cores in Yamal and the use of Wikipedia graphs in United Nations official climate reports.

But warmers don’t like it when we do this,  they simply want us to “get out of the way”: Read the rest of this entry »

United Nations Pulls Hockey Stick from Climate Report

5 10 2009
CCEP_report_cover

United Nations Climate Change Science Compendium - click for PDF

WUWT readers may recall that Steve McIntyre’s Climate Audit blog discovery of  UNEP’s use of a Wikipedia “hockey Stick” graphic by “Hanno”, was the subject of last week’s blog postings.

The Yamal data hockey stick  controversy overshadowed it, and much of the focus has been there recently.

The discovery of a Wikipedia graphic in the UNEP Climate Change Science Compendium must have been embarrassing as  it shows the sort of sloppy science that is going into “official” publications.

In this case, the United Nations simply grabbed an image from Wikipedia that supported the view they wanted to sell. The problem with the graph in the upper right of page 5 of the UNEP report is that it itself has not been peer reviewed nor has it originated from a peer reviewed publication, having its inception at Wikipedia.

And then there’s the problem of the citation as  “Hanno 2009” who (up until this story broke) was an anonymous Wikipedia contributor.

Yet UNEP cited the graph as if it was a published and peer reviewed work as “Hanno 2009″.

Here’s my screencap of the page from the UNEP Climate Change Science Compendium report from last week

In this case, the United Nations simply grabbed an image from Wikipedia that supported the view they wanted to sell.

The hockey stick, based on tree ring proxies has met an inconveniently timed death it seems.

It appears now that somebody at the United Nations must have gotten the message from blogland, becuase there has been a change in the graphics on page 5.

Below is page 5 as it appears in the UNEP Climate Change Science Compendium today:

Ross McKitrick sums up the Yamal tree ring affair in the Financial Post

2 10 2009

For those who don’t know, Ross McKitrick of the University of Guelph co-authored the first paper with Steve McIntyre debunking Michael Mann’s first Hockey Stick paper, MBH98. Ross wrote this essay in today’s Financial Post, excerpts are below. Please visit the story in that context here and patronize their advertisers. – Anthony

Flawed climate data

Only by playing with data can scientists come up with the infamous ‘hockey stick’ graph of global warming

Ross McKitrick,  Financial Post

Friday, October 2, 2009

Beginning in 2003, I worked with Stephen McIntyre to replicate a famous result in paleoclimatology known as the Hockey Stick graph. Developed by a U.S. climatologist named Michael Mann, it was a statistical compilation of tree ring data supposedly proving that air temperatures had been stable for 900 years, then soared off the charts in the 20th century. Prior to the publication of the Hockey Stick, scientists had held that the medieval-era was warmer than the present, making the scale of 20th century global warming seem relatively unimportant. The dramatic revision to this view occasioned by the Hockey Stick’s publication made it the poster child of the global warming movement. It was featured prominently in a 2001 report of the U.N. Intergovernmental Panel on Climate Change (IPCC), as well as government websites and countless review reports.

Steve and I showed that the mathematics behind the Mann Hockey Stick were badly flawed, such that its shape was determined by suspect bristlecone tree ring data. Controversies quickly piled up: Two expert panels involving the U.S. National Academy of Sciences were asked to investigate, the U.S. Congress held a hearing, and the media followed the story around the world.

The expert reports upheld all of our criticisms of the Mann Hockey Stick, both of the mathematics and of its reliance on flawed bristlecone pine data.YAMAL.eps

…

Most of the proxy data does not show anything unusual about the 20th century. But two data series have reappeared over and over that do have a hockey stick shape. One was the flawed bristlecone data that the National Academy of Sciences panel said should not be used, so the studies using it can be set aside. The second was a tree ring curve from the Yamal Peninsula in Siberia, compiled by UK scientist Keith Briffa. Read the rest of this entry »

Carbon Credit Market Imploding: CCX now 10 cents a tonne

1 10 2009

Obverse

We knew this was coming. Carbon Financial Instruments are now trading for 10 cents per metric tonne on the Chicago Climate Exchange. I wonder if the investors are reacting to the Hockey Stick Implosion news? As reported on WUWT, less than one month ago it was 25 cents a tonne, and a year ago it was over 1 dollar.  The all time high was May 2008 at over 7 dollars a tonne. Today: poof.

Response from Briffa on the Yamal tree ring affair – plus rebuttal

1 10 2009

First here is Dr. Keith Briffa’s response in entirety direct from his CRU web page:

Dr_Keith_Briffa

Dr. Keith Briffa of the Hadley Climate Research Unit - early undated photo from CRU web page

My attention has been drawn to a comment by Steve McIntyre on the Climate Audit website relating to the pattern of radial tree growth displayed in the ring-width chronology “Yamal” that I first published in Briffa (2000). The substantive implication of McIntyre’s comment (made explicitly in subsequent postings by others) is that the recent data that make up this chronology (i.e. the ring-width measurements from living trees) were purposely selected by me from among a larger available data set, specifically because they exhibited recent growth increases.

This is not the case. The Yamal tree-ring chronology (see also Briffa and Osborn 2002, Briffa et al. 2008) was based on the application of a tree-ring processing method applied to the same set of composite sub-fossil and living-tree ring-width measurements provided to me by Rashit Hantemirov and Stepan Shiyatov which forms the basis of a chronology they published (Hantemirov and Shiyatov 2002). In their work they traditionally applied a data processing method (corridor standardisation) that does not preserve evidence of long timescale growth changes. My application of the Regional Curve Standardisation method to these same data was intended to better represent the multi-decadal to centennial growth variations necessary to infer the longer-term variability in average summer temperatures in the Yamal region: to provide a direct comparison with the chronology produced by Hantemirov and Shiyatov.

These authors state that their data (derived mainly from measurements of relic wood dating back over more than 2,000 years) included 17 ring-width series derived from living trees that were between 200-400 years old. These recent data included measurements from at least 3 different locations in the Yamal region. In his piece, McIntyre replaces a number (12) of these original measurement series with more data (34 series) from a single location (not one of the above) within the Yamal region, at which the trees apparently do not show the same overall growth increase registered in our data.

More Yamal tree ring temperature data: this data is flat as roadkill

30 09 2009

Today while looking for something else I came across an interesting web page on the National Climatic Data Center Server that showed a study from 2002

A continuous multimillennial ring-width chronology in Yamal, northwestern Siberia (PDF) by Rashit M. Hantemirov and Stepan G. Shiyatov

That study was tremendously well done, with over 2000 cores, seemed pretty germane to the issues of paleodendroclimatology we’ve been discussing as of late. Jeff Id touched on it breifly at the Air Vent in Circling Yamal – delinquent treering records?

A WUWT readers know, the Briffa tree ring data that purports to show a “hockey stick” of warming in the late 20th century has now become highly suspect, and appears to have been the result of hand selected trees as opposed to using the larger data set available for the region.

OK,  first the obligatory Briffa (Hadley Climate Research Unit) tree ring data versus Steve McIntyre’s plot of the recently available Schweingruber data from the same region.

http://wattsupwiththat.files.wordpress.com/2009/09/rcs_chronologies_rev2.gif?w=420&h=360&h=360

Red = Briffa's 12 hand picked trees Black = the other dataset NOT used

The Hantemirov- Shiyatov (HS) tree ring data that I downloaded from the NCDC is available from their FTP server here. I simply downloaded it and plotted it from the present back to the year 0AD (even though it extends much further back to the year 2067 BC) so that it would have a similar x scale to the Briffa data plot above for easy comparison. I also plotted a polynomial curve fit to the data to illustrate trend slope, plus a 30 year running average since 30 years is our currently accepted period for climate analysis.

Compare it to the Briffa (CRU) data above. Read the rest of this entry »

AGU presentation backs up McIntyre’s findings that there is no late 20th century hockey stick in Yamal

30 09 2009

If you are just joining us, the story is this. After 10 years of data being withheld that would allow true scientific replication, and after dozens of requests for that data, Steve McIntyre of Climate Audit finally was given access to the data from Yamal Peninsula, Russia. He discovered that only 12 trees had been used out of a much larger dataset of tree ring data. When the larger data set was plotted, there is no “hockey stick” of temperature, in fact it goes in the opposite direction. Get your primer here.

http://wattsupwiththat.files.wordpress.com/2009/09/rcs_chronologies_rev2.gif?w=420&h=360&h=360

Red = 12 hand picked Yamal trees Black = the rest of the Yamal dataset

Now there’s independent confirmation from a study presented at the American Geophysical Union Conference in 2008 that there is no “hockey stick of warming” at Yamal.

The presentation is” Cumulative effects of rapid climate and land-use changes on the
Yamal Peninsula, Russia by D.A. Walker, M.O. Leibman, B.C. Forbes, H.E. Epstein. (click link for PDF)

In the hallway poster for their AGU presentation, they have this graph, with the caption saying a “nearly flat temperature trend” for Yamal, especially for the late 20th century period where the “hockey stick” from those 12 trees emerges:

A must read: The Yamal Hockey Stick Implosion in laymans terms

30 09 2009

WUWT readers may remember when Bishop Hill wrote Caspar and the Jesus paper. It was a wonderful narrative of the complex subject of tree rings and Steve McIntyre’s quest with debunking the Mann MBH98 paper, which created the original hockey stick. Now Bishop Hill has done it again with another great narrative. – Anthony

The Yamal implosion

DateSeptember 29, 2009

There is a great deal of excitement among climate sceptics over Steve McIntyre’s recent posting on Yamal. Several people have asked me to do a layman’s guide to the story in the manner of Caspar and the Jesus paper. Here it is.

The story of Michael Mann’s Hockey Stick reconstruction, its statistical bias and the influence of the bristlecone pines is well known. McIntyre’s research into the other reconstructions has received less publicity, however. The story of the Yamal chronology may change that. Read the rest of this entry »

More broken hockey stick fallout: Audit of an Audit of an Auditor

29 09 2009

http://www.blisstree.com/files/232/2008/11/magnifying-glass.jpgFor those that don’t read a lot of the WUWT comments closely, there has been a scholarly argument going on between  Tom P of the UK and several WUWT commentators over the methodology Steve McIntyre used to illustrate the “breathtaking difference” between the plot of  the hand picked set of 12 Yamal trees and the larger Schweingruber tree ring data set also from Yamal. Tom P. reworked Steve’s R-code script (which he posted on WUWT) to include both the 12 excluded and the Schweingruber and  thought he found “insensitivity to additional data”, saying “There is no broken hockeystick”.

Jeff Id audited the auditor of an auditor and found that Steve’s work still holds up “robustly”. – Anthony

Jeff Id writes on The Air Vent

Just a short post tonight I hope. Tom P, an apparent believer in the hockey stick methods posted an entertaining reply to Steve McIntyre’s recent discoveries on Yamal. He used R code to demonstrate a flaw in SteveM’s method. His post was on WUWT, brought to my attention by Charles the moderator and is copied here where he declares victory over Steve.

Tom P writes on WUWT:

===========

Steve McIntryre’s [sic] reconstructions above are based on adding an established dataset, the Schweingruber Yamal sample instead of the “12 trees used in the CRU archive”. Steve has given no justification for removing these 12 trees. In fact they probably predate Briffa’s CRU analysis, being in the original Russian dataset established by Hantemirov and Shiyatov in 2002.

One of Steve’s major complaint about the CRU dataset was that it used few recent trees, hence the need to add the Schweingruber series. It was therefore rather strange that towards the end of the reconstruction the 12 living trees were excluded only to be replaced by 9 trees with earlier end dates.

I asked Steve what the chronology would look like if these twelve trees were merged back in, but no plot was forthcoming. So I downloaded R, his favoured statistical package, and tweaked Steve’s published code to include the twelve trees back in myself. Below is the chronology I posted on ClimateAudit a few hours ago.

Broken Hockey Stick Fallout: Leading UK Climate Scientists Must Explain or Resign

29 09 2009

If you are just joining us, first you should read about what started it all here.

While Realclimate.org continues deleting the ongoing river of comments posted on their threads ( Note: Any of you who find that your posts to those sites are being rejected {as usual without any explanation} can keep a copy of the post, and post it at http://rcrejects.wordpress.com if you want. Keep those screencaps going folks) asking about the McIntyre Yamal data development, Jennifer Marohasy of Australia is drawing a bit of a line in the sand. Given the churlishness of the Team and the blockades put up by Hadley, I can’t say that I blame her stance. – Anthony

Leading UK Climate Scientists Must Explain or Resign

Jennifer_marohasyBy Jennifer Marohasy

MOST scientific sceptics have been dismissive of the various reconstructions of temperature which suggest 1998 is the warmest year of the past millennium.    Our case has been significantly bolstered over the last week with statistician Steve McIntyre finally getting access to data used by Keith Briffa,  Tim Osborn  and Phil Jones to support the idea that there has been an unprecedented upswing in temperatures over the last hundred years –  the infamous hockey stick graph.

Mr McIntyre’s analysis of the data – which he had been asking for since 2003 – suggests that scientists at the Climate Research Unit of the United Kingdom’s Bureau of Meteorology  have been using only a small subset of the available data to make their claims that recent years have been the hottest of the last millennium.   When the entire data set is used, Mr McIntyre claims that the hockey stick shape disappears completely. [1]

http://wattsupwiththat.files.wordpress.com/2009/09/rcs_chronologies_rev2.gif?w=420&h=360

Red - before new data Black - after new data

Mr McIntyre has previously showed problems with the mathematics behind the ‘hockey stick’.   But scientists at the Climate Research Centre, in particular Dr Briffa, have continuously republished claiming the upswing in temperatures over the last 100 years is real and not an artifact of the methodology used – as claimed by Mr McIntyre.     However, these same scientists have denied Mr McIntyre access to all the data.    Recently they were forced to make more data available to Mr McIntyre after they published in the Philosophical Transactions of the Royal Society  -  a journal which unlike Nature and Science has strict policies on data archiving which it enforces.   Read the rest of this entry »

Update: A zoomed look at the broken hockey stick

28 09 2009

Steve McIntyre published an update tonight showing the last 200 years of the Yamal tree ring data versus the archived CRU tree ring data used to make the famous hockey stick. For those just joining us, see the story here.

First here’s the before an after at millennial scale.

Steve McIntyre writes:

The next graphic compares the RCS chronologies from the two slightly different data sets: red – the RCS chronology calculated from the CRU archive (with the 12 picked cores); black – the RCS chronology calculated using the Schweingruber Yamal sample of living trees instead of the 12 picked trees used in the CRU archive. The difference is breathtaking.

A look at treemometers and tree ring growth

28 09 2009

peanuts_treemometerSince there has been a huge amount of interest in Steve McIntyre’s recent discovery of what happens to the “hockey stick” when all of the Yamal tree ring data is used rather than a special subset of 10, I thought it might be a good time to talk about how tree rings are grown.

Several readers have correctly pointed out that trees don’t respond just to temperature. The also respond to available water, available nutrients in soil, and available sunlight. For example, the only time in modern history where some trees did not produce summer growth rings occurred in the year 1816, also known as the Year Without a Summer:

Many consider the Year Without a Summer to have been caused by a combination of a historic low in solar activity (The Dalton Minimum) and a volcanic winter event; such as the powerful Mount Tambora eruption in 1815 which had four times the power of the famous Krakatoa eruption and hurled huge amounts of aerosols into the atmosphere.

Obviously, sunlight was a limiting factor for tree growth then, reduced temperature also figured in.

I touched on the idea of trees used for dendroclimatology being rain gauges before: Bristlecone Pines: Treemometers or rain gauges ? There has obviously been years of drought when trees also did not grow as much, so how do we separate temperature and moisture in the growth analysis?

But, right now what I really want to introduce readers to is Leibig’s Barrel. Read the rest of this entry »

Steve McIntyre’s ICCC09 presentation with notes

18 03 2009

I sat next to Steve on the Climatology Panel at ICCC09 and thought he did a fine job of summarizing the Mannian methodology and the Bristlecone Pine issues for the general public. Jeff Id invited me to repost this from his blog, the Air Vent, and am more than happy to oblige so that it gets the widest possible exposure. Note, unlike at the Air Vent, this thread will be TCO free since we don’t allow cussing here. ;-) – Anthony

I’ve taken the time to post Steve McIntyres speech notes for the 2009 IPCC presentation along with the slides. It gives a much more complete view of the devastating presentation about Global Warming alarmism and IMO is a must read. SteveM’s notes for the speech are in Blue, as he says it he seldom uses the wording in the slides.
