Hiding The Decline : Iowa Temperatures Plummeting For 120 Years

The graph below shows measured maximum daily temperatures for all USHCN stations in Iowa with records going back to the year 1900. recent years have been 5-9 degrees cooler than the 1930s.

The next graph shows all-time record maximums set or tied at all long-term stations. Recent years have been near the bottom of both graphs.

Even UHI contaminated average temperatures show a decline.

Our friends at NOAA have turned this decline into a warming trend, because it is important for funding to make sure that the public believes in global warming.

    I like that the record maximum and minimum temperatures inform the historic climate record without the need for the obscure TOBS adjustments.

    • The TOBS adjustment is a fraud. USHCN1 showed no additional TOBS after 1990, but USHCN 2 shows it steadily increasing. Neither the algorithm nor the station data changed, which means that they are cheating.

  2. Andy DC says:

    The minute agenda driven people start making “adjustments”, the data is contaminated. Just the way Mayor Daley contaminated the Illinois vote during the election of 1960. It is commonly referred to as CHEATING.

    Most people have no idea this cheating is taking place. How do we get the word out?

    The AGW theory, the computer models, the political consensus, and the ballyhoo publicity, have said that with this level of CO2 in the atmosphere, dictates that the planet must get warmer.

    Historical records and current state of the climate will show this scam for what it is. A plan to recover all the money from the charlatans is what’s required.
