The world isn't warming--data is no good

I apologize for being absent for the past 3 weeks or so. I have had many things I have had to do.

A friend just sent me an article to the Times (UK) which basically verifies what this blog has been saying for quite a while, that the temperature record is not reliable. I have shown that the temperatures measured at two closely spaced towns are terribly inconsistent due to heat sources.

The article cites research by Christy and other research by McKittrick.

"Christy has published research papers looking at these effects in three different regions: east Africa, and the American states of California and Alabama.

“The story is the same for each one,” he said. “The popular data sets show a lot of warming but the apparent temperature rise was actually caused by local factors affecting the weather stations, such as land development.”

The IPCC faces similar criticisms from Ross McKitrick, professor of economics at the University of Guelph, Canada, who was invited by the panel to review its last report.

The experience turned him into a strong critic and he has since published a research paper questioning its methods.

“We concluded, with overwhelming statistical significance, that the IPCC’s climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias,” he said."


To refresh everyone's memory of how bad and inconsistent the temperature record is, look at the temperature difference between Stillwater, Oklahoma and Perry, Oklahoma, towns merely 16 miles apart. I subtracted Perry's daily temperature from Stillwater's and then averaged each year. Notice how these YEARLY averages vary over such a small difference, sometimes favoring Stillwater, and sometimes favoring Perry.

Think also in terms of wind direction. We know that wind blows from the hot regions to the cold regions. The predominant winds in Oklahoma are from the west and southwest. Temperature differences like those seen below should impact the average wind direction--of course nothing is observed along those lines so the temperatures probably aren't real.

    Phil Jones is also now saying that there has been no statistical warming since 1995.
    Professor Jones also conceded the possibility that the world was warmer in medieval times than now – suggesting global warming may not be a man-made phenomenon.

    And he said that for the past 15 years there has been no ‘statistically significant’ warming.

    Just because the records are bad does not mean that the world is not warming. It means that we can't tell what is going on.

    Just because the records are bad does not mean that the world is not cooling. It means that we can't tell what is going on.


  4. I hope you were giving a deposition in the Texas vs EPA case.
