List: cc Kevin and Crispin 

1. This needs only a little reply - nothing from Kevin on the content of my 
reply to Crispin - only on my introduction. 

2. Crispin had a medium, selective reply (nothing on any of my cites, mostly 
repeats of some of his original), .sent only to me. I have just asked if his 
reply could be shared. 

3. Kevin says below: " # I feel it is rather apparent that Crispin simply wants 
to focus on topics relevant to the Stoves List. "Believer Issues" are not 
relevant to the Stoves List. 
I had 6 responses below Crispin's - none of which used the word "stoves", nor 
had anything overt (I think hidden, though) to do with stoves. The reason I 
wrote is precisely because I found nothing (repeat nothing) on stoves (overt) 
in Crispin's message of yesterday. I look forward to hearing the " rather 
apparent " that I missed. 
Yes, I admit to responding as a "believer" - but only when I am trying to show 
how climate-nonsensical is almost everything I read from climate-deniers. 
Talking about a sudden CO2 swing around 1940 up to 450 ppm and back in a decade 
or so is the most ludicrous one I have seen. Where does that appear in print 
except Beck, Crispin, and WUWT? 

4. Kevin: Below your sign-off below, after the above in bold and four others, 
is your usual phrase: "# Inserts below.".. I don't find any such # inserts 
below it,

List cc Crispin 

Apologies in advance. If you don't want to read about the relationship between 
climate denial and stoves, stop reading now. 

# You are turning the Bioenergy Lists into a Bully Pulpit to promote your 
"Controversial Believer Views". Your apology is meaningless unless you mend 
your ways and confine your comments relating to "Believer Issues" to "Believer 
Forums." 

This is my attempt to analyze why Crispin's email below (today) was written. 

# I feel it is rather apparent that Crispin simply wants to focus on topics 
relevant to the Stoves List. "Believer Issues" are not relevant to the Stoves 
List. 

Crispin is in blue; I am in black and preceded by bold [RWL.... 
This is substantially different from the last exchange I have had like this. 

# If you are referring to our "exchange" on teh Biochar-Policy List, I see many 
similarities to "the road you are going down." 
Points I have observed from our "exhange are: 
"Your general approach, when responding to points that conflict with your 
present views, seems to be one or more of the following: 
* to ignore such points 
* to respond with Ad Hominum attacks and insults 
* to evade the issue by introducing new topics 
* to restate your opinion and present it as a fact to show that you are 
correct. 
* to quote IPCC sources to support IPCC positions." 
This "exchange" is shaping up the same way. I hope you will try to be more 
professional in future "exchanges." 

I see no other place than "stoves" to offer this rebuttal of material 

# Please take your "Believer Discussions" to "Believer Forums." If "Stoves List 
Members" have an interest in "Believer Issues" they can decide for themselves 
if they want to go there. The Pope, as Head of the Catholic Church, and the 
Queen of England, as Head of the Church of England, are respectful of each 
other and neither attempts to crash the other's gigs. 

which I consider very dangerous for the stove community. 

# As requested in our other exchange several times, but which you failed to do, 
please show why Stove Development cannot "fly on its own." If you can't show 
this, then you are doing the Stoves List a great disservice by introducing 
diversionary "Believer Issues" at every opportunity . There is a place for 
"Full Fuel Combustion Stoves, where the efficiency of utilization is important 
to the Stove Owner. There is also a place for "Char Producing Stoves", when the 
production of char is desired by the Stove Owner. It is perverted and dishonest 
to attempt to manipulate Stove Testing Protocols through "Believer Concerns", 
simply to promote Char Making stoves. Both stove systems should rise or fall on 
their own honest merits.

Dear Friends 



There were a couple of inaccurate statements made in the past few days about 
the recording (since the 1950’s) of CO2, its level now and its level over the 
period of time during which measurements have been made. 




RWL1: Aha! It took awhile, but I found at least one list culprit - Richard 
Stanley you better apologize. On Sunday, you said 
"....we just past the reported tipping point of 400 ppm co2 apparently." 

Such inaccuracy cannot be tolerated on this list, which deals so extensively 
with scientific precision. 
You were off by more than one part in 10 million.  Anyone else who said the 
word "400" had better fess up, also. 




CO2 has been measured for 185 years first using a chemical process (some 10’s 
of thousands of measurements made at many locations). The precision ranges from 
extremely good (better than 1 part in 1000) to 1 part in 30. 



http://www.anenglishmanscastle.com/180_years_accurate_Co2_Chemical_Methods.pdf 



This work has been ignored by the IPCC which for some reason claims the level 
was constant and less than 300 ppm, ignoring actual measurements. 

[RWL2a : There is no evidence that the IPCC has ignored this paper. Beck's 
publication in 2007 was a year after the deadline for inclusion in IPCC AR4. 
Maybe it will be discussed be in AR5. I hope they discuss and knock it down The 
reason is In what I found in the material in italics about this paper at: 
http://www.realclimate.org/index.php/archives/2007/05/beck-to-the-future/ : 







"The list of arguments against such variability in the carbon cycle is too long 
even for a post on RC but here are a few of the main ones: 

    • The fluxes necessary to produce such variations are just unbelievably 
huge. Modern fossil fuel emissions are about 7.5GT (Giga Tons) Carbon per year 
which would correspond to about 3.5ppm increase per year (except that about 
half is absorbed by natural sinks in the ocean and the terrestrial biosphere). 
Beck’s supposed 150ppm source/sink in a decade corresponds therefore to a CO 2 
production/absorption about ten times stronger than the entire global 
industrial production of 2007 (putting aside for the moment additional 
complications since such CO 2 levels had to be equilibrated at least partly 
with the ocean and the real CO 2 source must even be larger). 
    • Such huge biospheric fluxes would leave an enormous 13 C signal in the 
atmosphere. Nothing remotely like that is observed in tree ring cellulose data. 
    • Beck makes an association of some of the alleged huge CO 2 peaks with 
volcanic eruptions. The Mauna Loa CO 2 record started by Charles Keeling 1955 
(http://cdiac.ornl.gov/, 
http://cdiac.ornl.gov/trends/co2/graphics/mlo145e_thrudc04.pdf ) however 
doesn’t show much variability associated with the big eruptions of El Chichon, 
Agung or Pinatubo. (Readers should know however that on much longer, geologic, 
timescales, CO 2 levels are heavily influenced by volcanic and tectonic 
activity, but that is not important on the interannual (or even centennial) 
timescale). 
    • The paper suggests that the CO 2 peak in the 1940 is forced by the first 
temperature rise in the 20th century. That would make 150ppm due to a 
temperature shift of 0.4°C. What happened then with the next rise from the 
1970s to today? The observed about 0.5°C rise corresponded to “only” 70ppm 
always assuming that fossil fuel combustion does not leave any remains in the 
atmosphere…. ;) 
    • And most importantly, we know from ice core analysis the CO 2 
concentration from the pre-industrial to modern times. The results of three 
different Antarctic cores broadly confirm the picture of an accelerating rise 
of CO 2 above levels of natural variability over the last 650.000 years 






CO2 has been measured in Hawaii since the late 1950’s using a different method. 
After a while it was upgraded. It shows a clear annual variation that coincides 
with northern hemisphere Spring and the melting of a huge amount of continental 
and Arctic ice and snow creating fresh water which absorbs a great deal of CO2 
– about 1125 ppm, drawing down the concentration by about 6 ppm until the 
re-freezing starts again. 




[RWL3a: Hmm. I understand the "6 ppm" part (maybe 10 at Moana Loa? Gets near 
zero in Antarctica) but 1125 ppm? Sounds like a total CO2 number being used 
about 50 Million years ago. Can this number be explained by someone? Also why 
is this topic being highlighted on this list? 





RWL 3b: Maybe it can be associated with this gem associated also with Beck: 

http://www.realclimate.org/index.php/archives/2007/06/curve-manipulation-lesson-2/
 










The CO2 concentration in the atmosphere rises and falls when the climate 
changes (see Figs 1 and 2 at the link immediately above) 




RWL4a : This was from an early version of the paper (saying "do not cite"). It 
was published later that year (with referees!) I found this site had good 
rebuttals of these 2 Beck figures: 


http://www.realclimate.org/wiki/index.php?title=E._G._Beck 





RWL4b: Among other rebuttals of Beck at this site, an exceptionally good one 
(based on many different types of measurements) on why the rise in CO2 is 
caused by fossil fuels (not what Beck (and apparently Crispin) are claiming) is 
this site 


http://www.ferdinand-engelbeen.be/klimaat/co2_measurements.html 







Correction to the other post: The current CO2 concentration has not risen above 
400 ppm – a correction was issued by NOAA (you heard about the correction in 
the media, right?) 



http://wattsupwiththat.com/2013/05/13/premature-400-ppm-fail-a-bration/#more-86162
 



http://www.latimes.com/news/science/sciencenow/la-sci-sn-carbon-dioxide-400-20130513,0,7196126.story
 



>From the LA Times article: 

“For the previous 800,000 years, CO 2 levels never exceeded 300 ppm, and…” 



This comment is erroneous and is contradicted by multiple sources. As ice cores 
show, the CO2 level lags temperature rises by about 800 years. As it was 
significantly (about 2 Deg C) warmer during the Minoan Climate optimum than it 
is now, it is highly likely that the CO2 level responded as normal during those 
millennia which means it rose. As there exist thousands of CO2 measurements 
made during a period long enough to experience significant climate cycles the 
idea that the temperature and the CO2 level were constant cannot be supported. 
Temperature, most importantly ocean temperature, has a significant though 
delayed effect on the CO2 concentration. How much has been contributed by 
burning fossil fuels is not clear as studies (based on isotopes) are not in 
agreement. 






RWL5: Going though this long section - topic by topic: 




5a An interesting snide remark about barely not making 400 ppm. Actually we are 
very close to the annual peak, so there is a chance NOAA (not IPCC) will be a 
year off. Not mentioned is that we are darn close to a full 3 ppm rise in the 
past year. As a "believer", I have to admit for NOAA's sake that I am pulling 
for that last 0.11 ppm. Admission: I was a post-Doc at NOAA- Boulder. I found 
it to be a good group. 





b. On the contrary, the LA Times article seems perfectly accurate to me. It 
seems probable, we didn't see 400 ppm for up to 35 million (not thousand) 
years. My source is Figure 5 in 




http://www.columbia.edu/~jeh1/2008/TargetCO2_20080407.pdf 




What counter source on 400 offered by Crispin? It is not in any cite on this 
page. Crispin is apparently arguing here that 400 ppm is common (certainly that 
is in the Beck material - but that has been discredited above). The ice core 
data, which I can find only going back 800 k years always is always below 300 
ppm (not 400 ppm) 





c. The whole lead-lag argument is denier bogus. This is a denial by denier 
Crispin that we have anything to worry about. There is a huge data base on ths 
issue and its relevance to the year 2013. This argument about what leads what 
is straight out of WUWT. 



d. Re the "Minoan" temperatures, see temperature plots for the holocene ( the 
Minoan period is about half way back) at 

http://en.wikipedia.org/wiki/Holocene_climatic_optimum 

Maybe(?) the Mediterranean was a bit hotter (probably not 2 degrees) , but all 
the global data shows only tiny wiggles back for almost 10,000 years. The 
attempt here is apparently to say 2 degrees is fine - lets look forward to it. 
A denier argument - and dangerous. And out of place on a stoves list unless you 
are trying to kill something being discussed 





e The "thousands of measurements" sentence is harking back to the discredited 
(above) arguments of Herr Beck - with my reminding you that Beck himself was a 
climate denier. See above. 

f. Re isotopes: See above very strong rebuttal of the "not-fossil" argument by 
Engelbeen (based in part on isotopes). I ask Crispin for the source/cite of his 
denial on fossil fuel causation. 




Ocean heat content, the main determinant of atmospheric temperatures, is a 
relatively new field of study and has been brilliantly captured by Bob Tisdale 
in his book on the subject. See 
http://wattsupwiththat.com/2013/05/14/multidecadal-variations-and-sea-surface-temperature-reconstructions/#more-86210
 for his most recent study (aimed at non-experts so it is quite appropriate). 



[RWL6a: see: 
http://www.skepticalscience.com/modeled-and-observed-ohc-is-there-a-discrepancy.html
 




6b. Is Tisdale a denier? I think his endorsement by WUWT probably merits that 
title, but I have just learned of this regular blogger at WUWT. I have skimmed 
through his very recent material (and the comments) which seems to revolve 
around placement of the origin of relatively small differences in T vs t plots. 
But I again ask why Crispin has brought it to our attention on this list? It 
would seem to support the reason why temperatures have appeared to be leveling 
off. 



6c. In further reading, I now believe this is all about the proper numerical 
value for climate sensitivity. Deniers want the number to be small. The range 
is somewhere between 1 and 8 (degrees C rise for a doubling of CO2). This is 
maybe the biggest problem for making predictions of the future. The IPCC says 
between 2 and 4.5. Jim Hansen is still at 3, I believe. I, who know very little 
on this topic, think Hansen is being intentionally (maybe dangerously) 
conservative. (I really admired an extensive analysis (By a Brit I will have 
trouble finding) proving 8 - all because of positive feed-backs like arctic 
methane (not in IPCC modeling). 





6d. Arguments about ocean temperatures are at the heart of this sensitivity 
dialog/argument. Which has no place on a list about stoves unless you want to 
downplay a type of stove that can be part of reversing ocean warming. Talking 
about unknowns on ocean energy content and time changes does explain why a 
stove-oriented denier might like to bring it up. Anyone have a better 
explanation for this whole message? Ron ]
