Dr John Christy, University of Alabama at Huntsville
Speaking
to a meeting in the Palace of Westminster in London, Professor John
Christy of the University of Alabama in Huntsville told MPs and peers
that almost all climate models have predicted rapid warming at high
altitudes in the tropics:
“They all have rapid warming above 30,000 feet in the tropics – it’s
effectively a diagnostic signal of greenhouse warming. But in reality
it’s just not happening. It’s warming up there, but at only about one
third of the rate predicted by the models.”
A similar discrepancy between empirical measurements and computer predictions has been confirmed at the global level:
“The global warming trend for the last 40 years, starting in 1979
when satellite measurements began, is +0.13C per decade or about half of
what climate models predicted.”
