Your survey wasn't of scientists. It was of petroleum engineers working the Alberta Tar Sands.
Golly, who could have predicted such a response?

Westwall -
Just in case I haven't mentioned this earlier - I now only read and respond posts by the the stonger, more on-topic posters. There is more to life than having to wade through you and glslack's gibberish and spam.
Hence, you are on ignore mode.
btw, If you are going to quote Schneider -try and do so honestly. You missed out this line:
On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but which means that we must include all the doubts, the caveats, the ifs, ands, and buts.
Your still unsubstantiated opinion is noted and set aside as you still can't back up what you're typing out.
Nice attempt at running, but it won't work. I'll just go right back to the point you're running from.
Scientists take a pay cut to be on the AGW side. Yet you accuse them of greed. How can someone be greedy for taking a pay cut? You claim money corrupts, but then you give your allegiance to the side that's been corrupted by money.

Saigon can debate rings around you and doesn't even need the A-game to do it. I wouldn't talk too much about others not backing up their shit, when you didn't provide a link either.Sure thing little one. Go ahead and slink back to your bedroom. The fact remains you are a liar and can't back up any of the bullshit you post and you can't stand it when someone like me calls you on your lies.
I get it. When you can't win you pack up your marbles and go home. So go away permanently you little twerp.

"Association of Professional Engineers, Geologists and Geophysicists of Alberta."
That is, mostly petroleum engineers.
One thing unique (sort of but not unlike mamooths methods) to saigon is the complete lack of fair quoting what he is responding to. He states the posters name thusly; gslack: and then commences to dishonestly misrepresent your post he is responding to and then debate that. Completely ignoring what you actually said and your post. He does this habitually and it is not only deliberate, but completely dishonest and unethical, which shows his claim of being a journalist to be a fabrication..
When you debate them know going in they are incapable of honesty and ethical behavior.
I am sure you would also agree that CO2 is cited by the overwhelming majority of scientists as being the main factor (but not the only factor) in rising temperatures.
Here is a list of papers establishing the link between CO2 and temperature:
Spectroscopic database of CO2 line parameters: 4300–7000 cm−1 – Toth et al. (2008) “A new spectroscopic database for carbon dioxide in the near infrared is presented to support remote sensing of the terrestrial planets (Mars, Venus and the Earth). The compilation contains over 28,500 transitions of 210 bands from 4300 to 7000 cm−1…”
Line shape parameters measurement and computations for self-broadened carbon dioxide transitions in the 30012 ← 00001 and 30013 ← 00001 bands, line mixing, and speed dependence – Predoi-Cross et al. (2007) “Transitions of pure carbon dioxide have been measured using a Fourier transform spectrometer in the 30012 ← 00001 and 30013 ← 00001 vibrational bands. The room temperature spectra, recorded at a resolution of 0.008 cm−1, were analyzed using the Voigt model and a Speed Dependent Voigt line shape model that includes a pressure dependent narrowing parameter. Intensities, self-induced pressure broadening, shifts, and weak line mixing coefficients are determined. The results obtained are consistent with other studies in addition to the theoretically calculated values.” [Full text]
Spectroscopic challenges for high accuracy retrievals of atmospheric CO2 and the Orbiting Carbon Observatory (OCO) experiment – Miller et al. (2005) “The space-based Orbiting Carbon Observatory (OCO) mission will achieve global measurements needed to distinguish spatial and temporal gradients in the CO2 column. Scheduled by NASA to launch in 2008, the instrument will obtain averaged dry air mole fraction (XCO2) with a precision of 1 part per million (0.3%) in order to quantify the variation of CO2 sources and sinks and to improve future climate forecasts. Retrievals of XCO2 from ground-based measurements require even higher precisions to validate the satellite data and link them accurately and without bias to the World Meteorological Organization (WMO) standard for atmospheric CO2 observations. These retrievals will require CO2 spectroscopic parameters with unprecedented accuracy. Here we present the experimental and data analysis methods implemented in laboratory studies in order to achieve this challenging goal.”
Near infrared spectroscopy of carbon dioxide I. 16O12C16O line positions – Miller & Brown (2004) “High-resolution near-infrared (4000–9000 cm-1) spectra of carbon dioxide have been recorded using the McMath–Pierce Fourier transform spectrometer at the Kitt Peak National Solar Observatory. Some 2500 observed positions have been used to determine spectroscopic constants for 53 different vibrational states of the 16O12C16O isotopologue, including eight vibrational states for which laboratory spectra have not previously been reported. … This work reduces CO2 near-infrared line position uncertainties by a factor of 10 or more compared to the 2000 HITRAN line list, which has not been modified since the comprehensive work of Rothman et al. [J. Quant. Spectrosc. Rad. Transfer 48 (1992) 537].” [Full text]
Spectra calculations in central and wing regions of CO2 IR bands between 10 and 20 μm. I: model and laboratory measurements – Niro et al. (2004) “Temperature (200–300 K) and pressure (70–200 atm) dependent laboratory measurements of infrared transmission by CO2–N2 mixtures have been made. From these experiments the absorption coefficient is reconstructed, over a range of several orders of magnitude, between 600 and 1000 cm−1.”
Collisional effects on spectral line-shapes – Boulet (2004) “The growing concern of mankind for the understanding and preserving of its environment has stimulated great interest for the study of planetary atmospheres and, first of all, for that of the Earth. Onboard spectrometers now provide more and more precise information on the transmission and emission of radiation by these atmospheres. Its treatment by ‘retrieval’ technics, in order to extract vertical profiles (pressure, temperature, volume mixing ratios) requires precise modeling of infrared absorption spectra. Within this framework, accounting for the influence of pressure on the absorption shape is crucial. These effects of inter-molecular collisions between the optically active species and the ‘perturbers’ are complex and of various types depending mostly on the density of perturbers. The present paper attempts to review and illustrate, through a few examples, the state of the art in this field.”
On far-wing Raman profiles by CO2 – Benech et al. (2002) “Despite the excellent agreement observed in N2 here, a substantial inconsistency between theory and experiment was found in the wing of the spectrum. Although the influence of other missing processes or neighboring bands cannot be totally excluded, our findings rather suggest that highly anisotropic perturbers, such as CO2, are improperly described when they are handled as point-like molecules, a cornerstone hypothesis in the approach employed.”
Collision-induced scattering in CO2 gas – Teboul et al. (1995) “Carbon-dioxide gas rototranslational scattering has been measured at 294.5 K in the frequency range 10–1000 cm−1 at 23 amagat. The depolarization ratio of scattered intensities in the frequency range 10–1000 cm−1 is recorded. The theoretical and experimental spectra in the frequency range 10–470 cm−1 are compared.”
The HITRAN database: 1986 edition – Rothman et al. (1987) “A description and summary of the latest edition of the AFGL HITRAN molecular absorption parameters database are presented. This new database combines the information for the seven principal atmospheric absorbers and twenty-one additional molecular species previously contained on the AFGL atmospheric absorption line parameter compilation and on the trace gas compilation.”
Rotational structure in the infrared spectra of carbon dioxide and nitrous oxide dimers – Miller & Watts (1984) “High-resolution infrared predissociation spectra have been measured for dilute mixtures of CO2 and N2O in helium. Rotational fine structure is clearly resolved for both (CO2)2 and (N2O)2, the linewidths being instrument-limited. This establishes that predissociation lifetimes are longer than approximately 50 ns.”
Broadening of Infrared Absorption Lines at Reduced Temperatures: Carbon Dioxide – Tubbs & Williams (1972) “An evacuated high-resolution Czerny-Turner spectrograph, which is described in this paper, has been used to determine the strengths S and self-broadening parameters γ0 for lines in the R branch of the ν3 fundamental of 12C16O2 at 298 and at 207 K. The values of γ0 at 207 K are greater than those to be expected on the basis of a fixed collision cross section σ.”
Investigation of the Absorption of Infrared Radiation by Atmospheric Gases – Burch et al. (1970) “From spectral transmittance curves of very large samples of CO2 we have determined coefficients for intrinsic absorption and pressure-induced absorption from approximately 1130/cm to 1835/cm.”
Absorption of Infrared Radiant Energy by CO2 and H2O. IV. Shapes of Collision-Broadened CO2 Lines – Burch et al. (1969) “The shapes of the extreme wings of self-broadened CO2 lines have been investigated in three spectral regions near 7000, 3800, and 2400 cm−1. … New information has been obtained about the shapes of self-broadened CO2 lines as well as CO2 lines broadened by N2, O2, Ar, He, and H2.”
High-Temperature Spectral Emissivities and Total Intensities of the 15-µ Band System of CO2 – Ludwig et al. (1966) “Spectral-emissivity measurements of the 15-µ band of CO2 were made in the temperature range from 1000° to 2300°K.”
Laboratory investigation of the absorption and emission of infrared radiation – Burch & Gryvnak (1966) “Extensive measurements of the absorption by H2O and CO2 have been made in the region from 0·6 to 5·5 microm. Two different multiple-pass absorption cells provided path lengths from 2 to 933 m, and sample pressures were varied from a few μHg to 15 atm. Approximately thirty new CO2 bands were observed and identified, and the strengths of the important bands determined. The H2O data provide enough information for the determination of the strengths and widths of several hundred of the more important lines. The wings of CO2absorption lines were found to be sub-Lorentzian, with the shapes depending on temperature, broadening gas, and wavelength in ways which cannot be explained by present theories. The absorption by H2O and CO2 samples at temperatures up to 1800°K has been studied from 1 to 5 microm. The transmission of radiation from hot CO2 through cold CO2 and from hot H2O through cold H2O has been investigated to determine the effect of the coincidence of emission lines with absorption lines.” Darrell E. Burch, David A. Gryvnak, Journal of Quantitative Spectroscopy and Radiative Transfer, Volume 6, Issue 3, May–June 1966, Pages 229–240, http://dx.doi.org/10.1016/0022-4073(66)90072-0.
Line shape in the wing beyond the band head of the 4·3 μ band of CO2 – Winters et al. (1964) “Quantitative absorpance measurements have been made in pure CO2 and mixtures of CO2 with N2 and O2 in a 10 m White Perkin-Elmer cell. With absorbing paths up to 50 m-atm, results have been obtained from the band head at 2397 cm−1 to 2575 cm−1.”
Emissivity of Carbon Dioxide at 4.3 µ – Davies (1964) “The emissivity of carbon dioxide has been measured for temperatures from 1500° to 3000°K over the wavelength range from 4.40 to 5.30 µ.”
Absorption Line Broadening in the Infrared – Burch et al. (1962) “The effects of various gases on the absorption bands of nitrous oxide, carbon monoxide, methane, carbon dioxide, and water vapor have been investigated.”
Total Absorptance of Carbon Dioxide in the Infrared – Burch et al. (1962) “Total absorptance… has been determined as a function of absorber concentration w and equivalent pressure Pe for the major infrared absorption bands of carbon dioxide with centers at 3716, 3609, 2350, 1064, and 961 cm−1.”
Rotation-Vibration Spectra of Diatomic and Simple Polyatomic Molecules with Long Absorbing Paths – Herzberg & Herzberg (1953) “The spectrum of CO2 in the photographic infrared has been studied with absorbing paths up to 5500 m. Thirteen absorption bands were found of which eleven have been analyzed in detail.”
The Infrared Absorption Spectrum of Carbon Dioxide – Martin & Barker (1932) “The complete infrared spectrum of CO2 may consistently be explained in terms of a linear symmetrical model, making use of the selection rules developed by Dennison and the resonance interaction introduced by Fermi. The inactive fundamental ν1 appears only in combination bands, but ν2 at 15μ and ν3 at 4.3μ absorb intensely.”
Carbon Dioxide Absorption in the Near Infra-Red – Barker (1922) “Infra-red absorption bands of CO2 at 2.7 and 4.3 μ. – New absorption curves have been obtained, using a special prism-grating double spectrometer of higher resolution (Figs. 1-3). The 2.7 μ region, heretofore considered to be a doublet, proves to be a pair of doublets, with centers at approximately 2.694 μ and 2.767 μ. The 4.3 μ band appears as a single doublet with center at 4.253 μ. The frequency difference between maxima is nearly the same for each of the three doublets, and equal to 4.5 x 1011. Complete resolution of the band series was not effected, even though the slit included only 12 A for the 2.7 μ region, but there is evidently a complicated structure, with a “head” in each case on the side of shorter wave-lengths. The existence of this head for the 4.3 μ band is also indicated by a comparison with the emission spectrum from a bunsen flame, and the difference in wave-length of the maxima of emission and absorption is explained as a temperature effect similar to that observed with other doublets.” [For free full text, click PDF or GIF links in the linked abstract page]
Ueber die Bedeutung des Wasserdampfes und der Kohlensäure bei der Absorption der Erdatmosphäre – Ångström (1900)
Observations on the Absorption and Emission of Aqueous Vapor and Carbon Dioxide in the Infra-Red Spectrum – Rubens & Aschkinass (1898) “Our experiments carried out as described above on the absorption spectrum carbon dioxide very soon showed that we were dealing with a single absorption band whose maximum lies near λ = 14.7 μ. … The whole region of absorption is limited to the interval from 12.5 μ to 16 μ, with the maximum at 14.7 μ.” [For free full text, click PDF or GIF links in the linked abstract page]

This is the proper and adult way to debate.. Notice the way I quoted your post and then responded to it thus?
Your childish refusal to properly quote people is getting old now socko.. It's quite clear why you do it, and it's inexcusable..

Actually, if you did look at the science, you would see that much of it is based on observational data on increases in both CO2 and temperature.
This is what you miss out on by not looking at the evidence.
