Putting together such a record isn’t at all easy. Weather stations weren’t really designed to monitor global climate. Long-standing ones were usually established at points of commerce, which tend to grow into cities that induce spurious warming trends in their records. Trees grow up around thermometers and lower the afternoon temperature. Further, as documented by the University of Colorado’s Roger Pielke Sr., many of the stations themselves are placed in locations, such as in parking lots or near heat vents, where artificially high temperatures are bound to be recorded.

So the weather data that go into the historical climate records that are required to verify models of global warming aren’t the original records at all. Jones and Wigley, however, weren’t specific about what was done to which station in order to produce their record, which, according to the IPCC, showed a warming of 0.6° +/– 0.2°C in the 20th century.

Now begins the fun. Warwick Hughes, an Australian scientist, wondered where that “+/–” came from, so he politely wrote Phil Jones in early 2005, asking for the original data. Jones’s response to a fellow scientist attempting to replicate his work was, “We have 25 years or so invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it?”

Reread that statement, for it is breathtaking in its anti-scientific thrust. In fact, the entire purpose of replication is to “try and find something wrong.” The ultimate objective of science is to do things so well that, indeed, nothing is wrong.
