Sublimation

The word sublimation has different meanings. One is from physics: Sublimation is when a substance passes directly from a solid to a gaseous state. Dry ice is one example.

Another meaning is in psychology, where sublimation is an unconscious defense mechanism, diverting instinct into personally and socially acceptable channels. Defense mechanisms may be healthy or they may be pathological. Here are some characteristics of a pathological defense mechanism:

  • the defense is rigid and exclusive
  • the defense is motivated more by past needs than present or future reality
  • the defense significantly misstates the present situation

Both definitions appear to apply to Anthropogenic Global Warming theory. The “settled science” is rapidly passing from solid to vapor, and the AGW proponents’ defense mechanisms are, if not clearly unhealthy, decidedly unscientific.

Doctor Phil Jones, director of the University of East Anglia’s Climatic Research Unit, may be making progress, however. He’s just admitted that there has been no global warming since 1995:

…And he said that the debate over whether the world could have been even warmer than now during the medieval period, when there is evidence of high temperatures in northern countries, was far from settled.

Of course, the computer models “proving” that humans are causing global warming heavily depend on there having been no global Medieval Warming Period. Michael Mann’s discredited hockey stick graph, for example, completely erases that warming.

Before Mann:

From first progress report of the IPCC -1990


After Mann:

From 3rd IPCC Assessment Report


Up until the mid 1990’s a global MWP was an undisputed fact for climate researchers. An MWP is still acknowledged by those who promote AGW, but they restrict its effects to the northern hemisphere, because, they say, “We don’t have much in the way of data for the southern hemisphere in that period.” So, as Dr. Jones says,

We know from the instrumental temperature record that the two hemispheres do not always follow one another. We cannot, therefore, make the assumption that temperatures in the global average will be similar to those in the northern hemisphere.

But it does not follow that we must, therefore, assume the opposite: That temperatures in the southern hemisphere definitely did not reflect a global average warming during the MWP. Why is it a better “assumption” that the MWP was NOT global? The answer is that if the MWP were global it seriously undermines AGW theory.

For Dr. Jones to admit the science is not settled is quite important. This was not his position a few weeks ago, before the East Anglia emails and computer code were leaked. Still, it is ironic that Dr. Jones defends his rejection of a global Medieval Warming Period based on lack of data, since he appears to have misplaced his own modern records: World may not be warming, say scientists
