We all know about UHI (Urban Heat Island) and how it affects
temperature (even AGW'er cultists acknowledge this point, though they claim their computer models account for UHI and can show temperature increases even after UHI is subtracted out of the data) But what about Urban CO2 island? Is is possible the Mauna Loa, Hawaii CO2 measuring site, run by the Keeling clique, is subject to CO2 from nearby urban areas like Honolulu? That the actual background CO2 level is much smaller? As also evidenced by other "non-Hawaiian" CO2 measuring stations? Can it be that the myth of the supposed "world mixing bowl" of the Mauna Loa site is just that, a myth? Yes, yes it can. See the below article synopsys from the CO2 climate change website. RL The Urban CO2 Dome of Mexico City Reference Velasco, E., Pressley, S., Allwine, E., Westberg, H. and Lamb, B. 2005. Measurements of CO2 fluxes from the Mexico City urban landscape. Atmospheric Environment 39: 7433-7446. What was done As the world's second largest city, the capital of Mexico is an urban center with a wide range of direct and indirect CO2 emissions from a mix of commercial, industrial, residential and mobile sources. In the present study, the authors installed an eddy covariance flux system to a height of 37 meters above the ground in a densely populated section of the city to investigate the diurnal flux of CO2 over the urban landscape. CO2 flux data were obtained over 23 days (7-29 April 2003) during the warm dry season, including a period of significantly reduced traffic during the Holy Week national holiday (14-20 April). What was learned Urban CO2 concentrations showed a clear diurnal pattern over the period of study with the highest concentrations (398 to 444 ppm, average of 421 ppm) occurring during the morning hours and the lowest concentrations (average of 375 ppm) occurring in the afternoon. The average CO2 flux over the 23-day period was predominately positive, indicating that the surrounding urban surface was a net source of CO2 to the atmosphere, and that CO2 uptake by urban vegetation was not sufficient to offset the CO2 release from anthropogenic sources. The authors also note that urban CO2 concentrations were an average of 20 ppm higher during the morning rush hour of the higher-traffic week prior to Holy Week and 14 ppm higher during the following week. CO2 concentrations were additionally found to be higher on weekdays versus weekends, which effect, in the words of Velasco et al., is "directly related to vehicular traffic," since the transportation sector accounts for approximately 60% of the urban CO2 emissions burden. What it means The results of this study add to the growing body of evidence that identifies the urban CO2 dome as a major, although localized, human-induced perturbation of the background rural environment.

There is nothing here worth the bandwith to debate it.
The "CO2 Science" website is run by a father and son team, the Idso family, both paid fossil fuel industry shills and notorious liars. According to "www.ExxonMobilsecrets.org," recent payoffs to these two from industry bagmen include: Craig Idso: Board of Academic and Scientific Advisors with Committee for a Constructive Tomorrow: $ 382,000 Chairman, Founder and Former President with Center for the Study of Carbon Dioxide & Global Change: $ 65,000 Expert with George C. Marshall Institute: $ 515,000 Sherwood Idso: Board of Academic and Scientific Advisors with Committee for a Constructive Tomorrow: $ 382,000 President with Center for the Study of Carbon Dioxide and Global Change: $ 65,000 Expert with George C. Marshall Institute: $ 515,000 The Idso's summaries of scientific articles are infamous for lies by omission. One would be wise to read the actual articles, even the abstracts of the articles, rather than to accept the half-truths of a summary on the Idso's "CO2 [pseudo] Science" web site. |

Care to debate urban heat island and/or CO2 island Roger, or just sling
mud? We're past the tipping point. Why are you even posting to this group anymore? The game is over. Now bend over and take it like the weasel you ****ing wetback spic****. |

But what about Urban CO2 island? Is is possible the Mauna Loa, Hawaii CO2 measuring site, run by the Keeling clique, is subject to CO2 from nearby urban areas like Honolulu? Honolulu is not really nearby. That the actual background CO2 level is much smaller? As also evidenced by other "non-Hawaiian" CO2 measuring stations? Can it be that the myth of the supposed "world mixing bowl" of the Mauna Loa site is just that, a myth? Yes, yes it can. Is it possible Klingons are using disruptors to heat up the planet? Yes, in the wacky world of Ray, anything is possible. See the below article synopsys from the CO2 climate change website.

Given the trade winds, it's upstream from Honolulu. There are also measurements in Antarctica showing the same values as on Hawaii, although a year or two later. Øyvind Seland |

That does not, however, explain the similar CO2 increases seen globally. Scott |
