| I think I heard of this; didn't they exclude something like 3/4 of the Russian stations? And the exclusion was heavily biased towards rural stations that hadn't been moved / seen much development? |

Yep - they teach the concept of urban heat islands in high school geography. If you start sampling more from urban areas of course you are going to show a warming trend. I guess these "scientists" missed those high school classes. |

Oh, I was aware of heat island effects - my post-secondary education was heavily focused on environmental sciences. Reading the article you linked brought to mind an exchange between me and a prof about ... 8 years ago, when the topic of global warming came up in a general macro ecology class. I made the comment that the small degree of warming measured could have quite a bit to do with urban heat islands. The prof replied that the effect couldn't possibly explain a worldwide trend, to which I replied that it could, if the monitoring stations were mostly located in cities. Oddly prescient, in a way. |

| do you think that these conspirators would use a tactic so simple: the urban heat island effect, to convince all these scientists? wouldn't it have to be more complicated? |

It's usually easier to convince those who has a predisposition to the conclusion you're pushing. It's even easier if there's funding involved.

It *is* a lot more complicated. The heat island effect has an impact on a tremendous number of temperature stations across the world, and the raw data 'generated' from the stations. Very, very few scientists have ever seen the raw data sets (of which there are only 4) on which pretty much the entire record of modern 'warming' is based. This is the equivalent of planting evidence to secure a conviction for which there was only circumstantial evidence to begin with. |

After what happened at East Anglia do you really think selective sampling is beyond these people? |
