    We have argued this point repeatedly, with the alarmist side saying that everyone should just cede to the authority of the scientists making up the data tables.

    Climategate showed that HADCRU vigorously adjusted the data and when they were asked to produce the raw data they said they had thrown it away.

    The Y2K bug fiasco showed that NASA GISS continuously adjusts the data to the point that outside studies using the GISS data set have to define which date of data they used in order for the findings to make sense.

    While many have called for an audit of temperature data, New Zealand actually forced their climate study organization to answer the tough questions about raw data and the adjustments made and the reasoning behind the adjustments. After a year of squirming and dodging questions the NIWA just gave up!

    I wonder what will happen when people decide to find out what is going on with North American data?

    Adjusting the data, it's how "ManMade" gets into the phrase "ManMade Global Warming"

    NASA has recently been caught deliberately shutting down northern, rural surface stations in favor of making more southern urban (heat island and read out compromised) stations.

    No fucking wonder we're getting bad data from the wizards of smurt.

    While I am doubtful that it will ever happen, I sure would like to see the results of an independent audit of american temperature data and the 'adjustments' that have been tacked on in the last few decades.

    edit- the temporary drop for 1998 in the middle of the graph was caused by a talented amateur who discovered a Y2K bug that went undiscovered until 2006. NASA's immediate fix made headlines for changing the order of america's hottest years. NASA's reversal of those changes after a few months did not.

    How many physical points on earth can the temperature be read and how many points are uses.

    I would guess for every billion points that data can be read only one point is used. I say there are trillions points of data not being utilized.

    Scientists using selective temperature data, skeptics say
    In the 1970s, nearly 600 Canadian weather stations fed surface temperature readings into a global database assembled by the U.S. National Oceanic and Atmospheric Administration (NOAA). Today, NOAA only collects data from 35 stations across Canada.

    Worse, only one station -- at Eureka on Ellesmere Island -- is now used by NOAA as a temperature gauge for all Canadian territory above the Arctic Circle.

    The Canadian government, meanwhile, operates 1,400 surface weather stations across the country, and more than 100 above the Arctic Circle, according to Environment Canada.

    Yet as American researchers Joseph D’Aleo, a meteorologist, and E. Michael Smith, a computer programmer, point out in a study published on the website of the Science and Public Policy Institute, NOAA uses “just one thermometer [for measuring] everything north of latitude 65 degrees.”

    --

    They say NOAA collects no temperature data at all from Bolivia -- a high-altitude, landlocked country -- but instead “interpolates” or assigns temperature values for that country based on data from “nearby” temperature stations located at lower elevations in Peru, or in the Amazon basin.

    The result, they say, is a warmer-than-truthful global temperature record.

    “NOAA . . . systematically eliminated 75% of the world’s stations with a clear bias towards removing higher latitude, high altitude and rural locations, all of which had a tendency to be cooler,” the authors say. “The thermometers in a sense, marched towards the tropics, the sea, and to airport tarmacs.”​

    It's easy to win if you stack the deck. If AGW scientists were gamblers, they wouldn't be allowed to set foot in any Vegas casino.

    I've come to the conclusion that the reason for so much disparity in the data is the lack of actual statistical procedures in the statistical practices. It's glaringly obvious that none of these scientists ever conducted a regression analysis on their data to catch things like this.

    The funny part is that their hubris gets the best of them and their ignorance is proven.
