Mystery Climate Mechanism May Counteract Global Warming
A new study by two physicists at the University of Rochester suggests there is a mechanism at
work in the Earth’s atmosphere that may blunt the influence of global warming, and that this mechanism is not accounted for in the computer models scientists currently use to predict the future of the world’s temperature. The researchers, David H. Douglass and Robert S. Knox, professors of physics, plotted data from satellite measurements of the Earth’s atmosphere in the months and years following the volcanic eruption of Mount Pinatubo in 1991. The results, published in an upcoming issue of Geophysical Research Letters (and now online), show that global temperatures dropped more and rebounded to normal significantly faster than conventional climate models could have predicted.
“All we did was chart the data,” says Douglass. “We can be confident that our numbers are accurate because we aren’t using computer models and assumptions; we’re using simple observations. Despite whatever models might say, the analysis of the actual data says that the atmosphere rebounded from the Pinatubo volcano much faster than was expected.” In addition, the analysis of Douglass and Knox showed that the amount of the cooling measured could be explained only if there was some mechanism producing a kind of self-correcting feedback. In other words according to Douglass “ This feedback mechanism prevented the Earth from becoming much colder.”
Note from Editor: Numerous scientists have debunked the idea of global warming, contrary to scare tactic articles like one covering James Gustave Speth's urge to spread the word..."Scientists urged to spread word on global warming"
According to one reader, as long as the debate continues to reveal how little we really know about global climate, our public policy and interventions should favor the "no regrets" approach. A "no regrets" policy takes positions which remain beneficial no matter which way the proof finally falls. For example, destroying national weath is not a "no-regrets" policy. Improving the fertility and depth of topsoil normall is. Similarly, a move toward the hydrogen economy as opposed to the carbon economy will normally be a no-regrets policy because of the reduction in particulates, etc. But in the meantime, do not let anyone get away with claiming "scientific consensus" on this matter. It does not exist. There is even less economic consensus.
