The New Religion

Icecap Note: First let me set the stage, New Zealand has had two very snowy and cold winters, and this winter started out with record cold and early snow in May and a cold June (here). New Zealand is in denial of the on-going climate reversal and like most countries has bought into man-made global warming and is considering 2020 emission targets. 

This account is from a New Zealand Scientist, Bryan Leyland, a New Zealand based Consulting Engineer specialising in hydropower, power systems and markets. It illustrates how this movement will not give up without a fight. In fact they think they have won the science or at least have succeeded in fooling the populace and are pressing to achieve their goals of controlling the rest of us at the expense of our quality of life and livelihoods.

“Last night I had the unpleasant experience of being present at a public meeting called by Nick Smith the Minister for climate change issues to discuss New Zealand’s 2020 emissions target. In the flyer it says “our target needs to be realistic so that we do not put our economy at risk or damage a good international reputation by failing to deliver. It must also be sufficient to protect the environment and associated economic and social benefits into the future.”

The meeting was at the Hyatt Regency ballroom. There would have been at least 300 people there. I would say that 90+ percent were convinced global warmers and at least 70% had been herded there by Greenpeace. Many of them had large posters with “40% by 2020 and on them. They were properly printed and cased in plastic. They would have cost several dollars each and I suspect that Greenpeace had been handing them out as people came into the hall. They must have invested several thousand dollars in this alone.

The whole show bore a strong resemblance to a “salvation circus”. There was a lot of “We have sinned! We must repent!” Hard science, evidence and economic realities did not come into it. But there were Godlike references to the IPCC!  The meeting started off with a presentation by Nick Smith that included the usual IPCC curves and the like. He made it very clear that he was totally convinced that man-made global warming was real and dangerous and something had to be done. But he also accepted that there were major problems as a result of the economic damage that might be done. However, he did quote a recent—and discredited—report that claims that the economic damage would be relatively minor.

He said the government would soon bring in an amendment to the emissions trading scheme. He made (as I recall) absolutely no mention of the select committee process and certainly no mention of the need to wait for the outcome of this process. He frequently referred to “carbon pollution” and mentioned the fact that we had to be sure of the science.  He also mentioned that he had had dinner that evening with Jim Salinger who was present in the room.
The chairman was Mike Lee of the Auckland regional Council. He made a short speech in which he made it absolutely clear that he had bought into the global warming religion. He made particular mention of the presence of Jim Salinger, Graeme Easte (Councillor) and Tariana Turia the co-leader of the Green party. I think he also mentioned the leader of Greenpeace who was in the same row as me sitting alongside Jim Salinger. All got great applause.

A third person who, I think, was involved in negotiations (it was not Tim Groser) also spoke briefly and then the floor was opened for questions. Mike Lee asked people make their presentations brief and stick to the question—“what should we do”. He then let the first speaker ramble on for more than five minutes. The second speaker was from Oxfam she rambled on for another five minutes and talked about the poor Cateret islanders who were sinking beneath rising seas levels and the fact that a recent floods in Bangladesh had killed hundreds of thousands of people. (I have worked in Bangladesh. The Brahmaputra floods regularly and the more people there are the more get drowned in a flood. But it is also true that the land area of Bangladesh is increasing—due to silt building new islands).

I was next in line to speak and I started off by pointing out that I was part owner of a small hydro scheme and so, unlike many people in this room, I was speaking against my own financial interests. (this was aimed at the Green party who have invested in wind farms - and many others In the room.) I then asked Nick Smith whether or not he would be taking scientific advice from a wide range of scientific views. He said that the National party relied entirely on the IPCC for their scientific advice as they were the ones who knew it all (or words to that effect). This was news to me! I tried to continue but Mike Lee handed over to the next one in line. I protested loudly and Nick Smith came to my rescue.

I then pointed out that the Carteret Islands were sinking due to tectonic plate movement and the woman from Oxfam’s statement was typical of the misuse of science associated with global warming.  I then went on to say that surely the only sensible policy was to take note of the fact that the world was cooling and we did not know whether or not it would warm or cool. But according to the Sun spots and the Pacific decadal oscillation, continued cooling was more likely than a return to warming and we knew that cooling would be seriously bad for the world. Therefore the government should stick to the line that no action will be taken until and if the warming trend restarts and it is firmly associated with man-made greenhouse gases. This went down like a lead balloon.

The next speaker was Jim Salinger who started off by making very disparaging remarks about me—he called me a denier and several other things. I protested and and asked him not to resort to personal attacks.  Mike Lee attacked me.  He said I had accused him of being a “balanced”. That was not true—what I’d actually done was shake his hand and told him that Stalin would have been proud of a speech that he had made advocating that people’s right to live where they liked should be taken away from them by the planners. I’m sure that Stalin would have been pleased with that - as he would have been with Mike’s attempt to stop me finishing what I had to say. All the remaining speakers ranted on—and that is a fair description—about various subjects.  One or to were definitely in a religious mode.  Many of them quoted the mantra “40% by 2020” and, for as long as I stayed, none of them made any constructive attempts to answer Nick Smith’s questions. In spite of some weak kneed pleas from Mike Lee, all of them ran over the two or three minutes he had requested as a limit and he made only the feeblest of attempts to stop them. I would have expected that a man in his position would have been an competent chairman. He was not. The meeting was supposed to stop at 9 PM but by 9:30 PM there was still a good 10 speakers lined up waiting to speak so I walked out in disgust. 

As a way of getting public feedback it was a total failure.  As I said before, it was a gift to the Green party and Greenpeace - at our expense. It also confirmed my belief that Greenpeace, the Green party and others see this as a wonderful attempt to destroy our economy and gain power over the people who refuse to swallow their nonsense.  They made an impressive job of making their presence felt and intimidating any other people who may have been inclined to speak up.”

How to Turn Away Investors: Green Police State Britain

By Jonathan Leake, Times On-Line

The boys in green are coming as the Environment Agency sets up a squad to police companies generating excessive CO2 emissions.

The agency is creating a unit of about 50 auditors and inspectors, complete with warrant cards and the power to search company premises to enforce the Carbon Reduction Commitment (CRC), which comes into effect next year.

Decked out in green jackets, the enforcers will be able to demand access to company property, view power meters, call up electricity and gas bills and examine carbon-trading records for an estimated 6,000 British businesses. Ed Mitchell, head of business performance and regulation at the Environment Agency, said the squad would help to bring emissions under control. “Climate change and CO2 are the world’s biggest issues right now. The Carbon Reduction Commitment is one of the ways in which Britain is responding.”

The formation of the green police overcomes a psychological hurdle in the battle against climate change. Ministers have long recognised the need to have new categories of taxes and criminal offences for CO2 emissions, but fear a repetition of the fuel tax protests in 2000 when lorry drivers blockaded refineries.

The central unit, based in Warrington, Cheshire, can call on the agency’s national network of hundreds of pollution inspectors, many of whom will soon be trained in CO2 monitoring.

It will also be able to demand energy bills from utilities without the companies under investigation knowing they are being watched. Perhaps most worrying for managers will be the publication of an annual league table ranking companies by performance in cutting emissions. The government hopes the potential shame of a lowly placing will drive organisations to greater energy efficiency.

Mitchell predicted the unit would audit about 1,200 businesses a year. The first stage would be a desk study of their energy bills and activities, followed by a visit when numbers do not add up. “The inspectors will carry warrant cards giving them powers of entry to collect evidence. We will also have access to company accounts with suppliers,” he said. Read more here.

Also in this New York Times Story, The Big Four of Accounting Will Be Among the Big Winners if U.S. Adopts Climate Law. Having helped companies explore the labyrinth of greenhouse gas regulation in Europe, the Big Four auditing and accounting firms are now moving quickly to build climate and carbon shops in the United States. Their goal is to stake claim to a business that could one day rival tax compliance and financial disclosure in size and scope.

Deloitte Touche Tohmatsu, Ernst & Young, KPMG and PricewaterhouseCoopers are the undisputed giants of the auditing, tax advisory and business consulting world. They boast a client list that includes thousands of the biggest names in the corporate world.

The four are already well-known in Europe for their carbon footprint accounting, abatement strategy consulting and emissions disclosure services as industries on the other side of the Atlantic are forced to comply with the European Union’s Emission Trading Scheme (ETS), but so far, their presence in America’s nascent carbon market has barely been recognized.

But that’s about to change. All four firms are in the midst of shifting experienced staff from places such as London and Copenhagen to New York and Washington.

Icecap Note: This is a frightening look into our future under a Waxman Markey Cap-and Tax legislation or EPA regulation. We have to stop them NOW. The last time we had green police was in Nazi, Germany. It is the height of irony that Al Gore likened this battle against global warming to the battle AGAINST the Nazi’s. The British should rebel against this assault on reason and their freedoms Temperatures have been cooling globally for 8 years, have not risen since 1995. This together with the cooling from the 1940s to the late 1970s acquits CO2 from any involvement in climate change. They should throw the politicians pushing this and the crazed greenies and all the profiteers out.

Real Climate Permits The Continued Presentation Of Misinformation

By Roger Pielke Sr., Climate Science

Over at Real Climate, quite a few of the comments that they post continue to incorrectly interpret the observed behavior of the global average upper ocean heat content changes and sea level rise over the last 5 years (see the misinformation in the comments on the Real Climate weblog More bubkes).

The authors of Real Climate, unfortunately, are permitting this erroneous information (and personal insults) to be posted without their comments and correction. Apparently, the balance provided by Gavin Schmidt that I reported on in my weblog Gavin Schmidt’s Interview On Media Hype On Climate Science Issues was just a fluke. In this weblog, I will correct two of the major errors made in number of the comments on the Real Climate website.

One of the commentators on Real Climate list three papers that purportedly refute the finding of no recent upper ocean warming and that the sea level rise has flattened since 2006 . These papers are (1) Levitus S. et al. (2009) Global ocean heat content 1955-2008 in light of recently revealed instrumentation problems Geophys. Res. Lett. 36, L07608; (2) Cazenave A. et al. (2009) Sea level budget over 2003-2008: A reevaluation from GRACE space gravimetry, satellite altimetry and Argo Glob. Planet. Change 65, 83-88; (3) Leuliette E.W. and Miller L. (2009) Closing the sea level rise budget with altimetry, Argo, and GRACE Geophys Res. Lett. 36, art # L0406.  I have already weblogged on two of these papers:

Sea Level Budget over 2003–2008: A Reevaluation from GRACE Space Gravimetry, Satellite Altimetry and Argo by Cazenave et al. 2008. This paper includes the text “From the results presented in this study, we see that confronting independent estimates of ocean and land contributions to sea level with altimetry results leads to a rather coherent picture for recent years variations. This can be summarized as follows: since 2003, sea level has continued to rise but with a rate (of 2.5 +/-0.4 mm/yr) somewhat reduced compared to the 1993-2003 decade (3.1+/-0.4 mm/yr).”

“The steric sea level estimated from the difference between altimetric (total) sea level and ocean mass displays increase over 2003-2006 and decrease since 2006. On average over the 5 year period (2003-2008), the steric contribution has been small (on the order of 0.3+/-0.15 mm/yr), confirming recent Argo results (this study and Willis et al., 2008).” This paper supports both conclusions in my recent weblogs (see and see) that the sea level rise has flattened and that the upper ocean heat content changes have been essentially flat since 2004.

On the Levitus et al paper, I weblogged on this in Comments On A New Paper ”Global Ocean Heat Content 1955-2008 In Light Of Recently Revealed Instrumentation Problems” By Levitus Et Al. 2009.

Even a causal view of the Levitus et al figure, which is reproduced in my weblog, shows that upper ocean heat content has been flat in their data for the last 4 years. The large rise just before than is suspicious (as I am told by colleagues working of this subject), and, moreover, is not consistent with the sea surface temperature trends for this time period (see the GISS data on the ocean surface temperature trends here at ).  Thus even the group that Gavin Schmidt works for (GISS) presents data with no sharp spike that is at all consistent with the Levitus et al analysis and, moreover, the GISS analysis shows that the global average sea surface temperature has been essentially flat since 2002!

All of these analyses are consistent with no significant heating in the upper ocean and a flattening of sea level rise, and even more clearly, that these climate metrics are not “progressing faster than was expected a few years ago”. Real Climate has it backwards; these climate metrics are changing less than was expected a few years ago!

The Leuliette et al paper states “An analysis of the steric and ocean mass components of sea level shows that the sea level rise budget for the period January 2004 to December 2007 can be closed, we find that the sum of steric sea level and the ocean mass component has a trend of 1.5 ± 1.0 mm/a over the period.”

This finding is not flat, but it is not still does not support the claim by Real Climate that this climate metric “is progressing faster than was expected a few years ago”. In fact, this rate of sea level rise is even less than reported in Cazenave et al 2009! Read more here.

How The US Temperature Record is Adjusted

By Michael Hammer, Jennifer Marohasy Blog

In the US, the National Oceanic and Atmospheric Administration (NOAA) collects, analyses and publishes temperature data for the United States.  As part of the analysis process, NOAA applies several adjustments to the raw data. If we consider, the below graph, which shows, their plot of the raw data (dark pink) and the adjusted data (pale pink), it is obvious that the adjustments have little impact on data from early in the 20th century but adjust later temperature readings upwards by an increasing amount.  This means that the adjustments will create an apparent warming trend over the 20th century.  [Click on the above chart for a better larger view, this chart can also be viewed here.

image

NOAA state that they adjust the raw data for five factors.  The magnitude of the adjustments are shown in Figure 2.

image
Figure 2.  Form of individual corrections applied by NOAA. The black line is the adjustment for time of observation.  The red line is for a change in maximum/minimum thermometers used.  The yellow line is for changes in station siting. The pale blue line is for filling in missing data from individual station records. The purple line is for UHI effects (this correction is now removed). Link to larger one here.

It is obvious that the only adjustment which reduces the reported warming is UHI which is a linear correction of 0.1F or about 0.06C per century, Figure 2.  Note also that the latest indications are that even this minimal UHI adjustment has now been removed in the latest round of revisions to the historical record.  To put this in perspective, in my previous article on this site I presented bureau of meteorology data which shows that the UHI impact for Melbourne Australia was 1.5C over the last 40 years equivalent to 3.75C per century and highly non linear.

Compare the treatment of UHI with the adjustments made for measuring stations that have moved out of the city centre, typically to the airport.  These show lower temperatures at their new location and the later readings have been adjusted upwards so as to match the earlier readings.  The airport readings are lower because the station has moved away from the city UHI.  Raising the airport readings, while not adding downwards compensation for UHI, results in an overstatement of the amount of warming. This would seem to be clear evidence of bias.  It would be more accurate to lower the earlier city readings to match the airport readings rather than vice versa.

Note also the similarity between the shape of the time of observation adjustment and the claimed global warming record over the 20th century especially the steep rise since 1970.  This is even more pronounced if one looks at the total adjustment shown in Figure 3 (again from the same site as Figure 1).  As a comparison, a recent version of the claimed 20th century global temperature record downloaded from GISSis shown in Figure 4 (not shown here but can be seen here).

image
Figure 3.  Magnitude of the total correction applied by NOAA - enlarged here.

Since the total corrections for the US look so similar to the claimed temperature anomaly, it begs the questions as to what the raw data looks like without any corrections.  Does it show the claimed rapidly accelerating warming trend claimed by the AGW advocates?  To determine this I took the raw data from the USHCN graph shown in Figure 1 and plotted this using a 5 year mean (blue trace), matching the smoothing in the NASA GISS profile shown in Figure 4.  The result is shown in Figure 5.  Please note that while the plot is one that I generated, the data comes directly from the raw data from Figure 1 published by NOAA.

image
Figure 5 Plot of raw temperature data versus time (from fig 1) 5 point smoothing. Vertical axis degrees Fahrenheit.  Red line is a linear trend line. Green line is a 2nd order (parabolic) trend line. Larger image here.

Clearly the shape of this graph bears no similarity at all to the graph shown in Figure 4.  The graph does not even remotely correlate to the shape of the CO2 versus time graph.  The warming was greatest in the 1930’s before CO2 started to rise rapidly.  The rate of rise in 1920, the early 1930’s and the early 1950’s is significantly greater than anything in the last 30 years.  Despite the rapid rise in CO2 since 1960, the 1970’s to early 1980’s was the time of the global cooling scare and looking at the graph in Figure 5 one can see why (almost 2F cooling over 50 years).

A linear least squares trend line, created using the Excel trend line function (Red trace) shows a small temperature rise of 0.09C per century which is far less than the rise claimed by AGW supporters and clearly of no concern.  However, the data shown in figure 5 bears little if any resemblance to a linear function.  One can always fit a linear trend line to any data but that does not mean the fitted line has any significance.  For example, if instead I fit a second order trend line (a parabolic) the result is extremely different.  That suggests a temperature peak around 1950 with an underlying cooling trend since.  Which trend line is the more significant one?  If there was really a strong underlying linear rise over the time period it should have shown up in the 2nd order trend line as well.  This suggests that it is questionable whether any relevant underlying trend can be determined from the data.

It would appear that the temperature rise profile claimed by the adjusted data is largely if not entirely an artefact arising from the adjustments applied (as shown in Figure 3), not from the experimental data record.  In fact, the raw data does not in any way support the AGW theory.

Based on this data, the US temperature data does not correlate with carbon dioxide levels.  The warming over the last 3 decades is completely unremarkable and if present at all is significantly less than occurred in the 1930’s.  It is questionable whether any long term temperature rise over the 20th century can be inferred from the data but if there is any it is far less than claimed by the AGW proponents.

The corrected data from NOAA has been used as evidence of anthropogenic global warming yet it would appear that the rising trend over the 20th century is largely if not entirely an artefact arising from the “corrections” applied to the experimental data, at least in the US, and is not visible in the uncorrected experimental data record.

This is an extremely serious issue.  It is completely unacceptable, and scientifically meaningless, to claim experimental confirmation of a theory when the confirmation arises from the “corrections” to the raw data rather than from the raw data itself.  This is even more the case if the organisation carrying out the corrections has published material indicating that it supports the theory under discussion.  In any other branch of science that would be treated with profound scepticism if not indeed rejected outright.  I believe the same standards should be applied in this case.

McIntyre on USHCN2’s “warmer” trend treatment of Orland: Detective Mike Hammer and USHCN

By Steve McIntyre

In my last post, I observed that NOAA’s Talking Points applied their new “adjustments” to supposedly prove that NOAA’s negligent administration of the USHCN network did not “matter”.

In order to illustrate the effect of the new methods in this post, I’ll compare the new adjustments (post-TOBS) to the old adjustments (post-TOBS) on a “good” station - Orland CA, a prototype “good” station, discussed at the outset of surfacestations.org, discussed at WUWT here and CA here in early 2007.

image

The station history for Orland (at CDIAC) says that it has been in its present location for (at least) most of the 20th century and has had minimal changes during that time, other than perhaps time-of-observation (TOBS). The TOBS adjustment is carried forward into USHCN-v2. As I understand it, NOAA’s New Adjustment Method replaces station-history based adjustments for instrumentation changes and station location (the latter formerly done in FILNET).

As a benchmark, here is the difference between FILNET (adjusted) and TOBS for Orland in the “old” USHCN. Adjustments in the 20th century are negligible - in keeping with station history information that indicates no changes in location.

image
“Old” USHCN Adjustments for Station Location and Instrument Changes

Now here is the net adjustment in the “New” USHCN. Two points jump out. Look first at the monthly adjustments at the right hand side. In the “old” method, there weren’t any adjustments to recent data - where metadata did not indicate any relevant change. In the “new” method, there are all sorts of jittery little adjustments. They seem to average out, but why introduce these jitters in the first place? It’s starting to look like a pointless Hansen-esque (ROW-style) adjustment that simply distorts the underlying data.

On a larger scale, the new adjustment noticeably increases the 20th century trend at Orland.

image

These graphics strongly indicate to me that the effect of the algorithm - regardless of whatever good intentions may underlie it - is that data from lower quality stations is being blended into the presently archived Orland data. I presume that something similar is happening to other “good” stations (though I’ve only examined one example so far.) (Note that Orland is a CRN3 station. However, its excellent continuity makes it a pretty attractive station for benchmarking and visually it doesn’t look a “bad” CRN3 station).

Based on this example, it looks like NOAA’s Talking Points comparison is between the overall average and 70 “adjusted” stations - AFTER the good stations have been adjusted. See post and comments here.

------------------------------

Along this same line, this post on Jennifer Marohasy’s blog by Michael Hammer shows how most of the warming in the USHCN comes from adjustments to the raw data.

In the US, the National Oceanic and Atmospheric Administration (NOAA) collects, analyses and publishes temperature data for the United States.  As part of the analysis process, NOAA applies several adjustments to the raw data. If we consider, the below graph, which shows, their plot of the raw data (dark pink) and the adjusted data (pale pink), it is obvious that the adjustments have little impact on data from early in the 20th century but adjust later temperature readings upwards by an increasing amount.  This means that the adjustments will create an apparent warming trend over the 20th century.  [Click on the above chart for a better larger view, this chart can also be viewed here.

It is obvious that the only adjustment which reduces the reported warming is UHI which is a linear correction of 0.1F or about 0.06C per century, Figure 2.  Note also that the latest indications are that even this minimal UHI adjustment has now been removed in the latest round of revisions to the historical record.  To put this in perspective, in my previous article on this site I presented bureau of meteorology data which shows that the UHI impact for Melbourne Australia was 1.5C over the last 40 years equivalent to 3.75C per century and highly non linear.
