A quite one-sided and scurrilous piece from the Daily Mail, which attempts to rubbish the latest paper from Christy and McNider.
John Christy’s paper, “Satellite Bulk Tropospheric Temperatures as a Metric for Climate Sensitivity”, is hardly controversial in itself. It claims that, based on satellite measurements, the rate of atmospheric warming has not accelerated since 1994. (Note – they are not saying that temperatures have stopped rising.)
To reach their conclusions, they have taken out the effect of the two major volcanic eruptions of El Chichon in 1982, and Pinatubo in 1991. They have also adjusted for ENSO changes.
Neither of these adjustments are in any way controversial or illegitimate, and other scientists have also attempted to calculate their effect previously. Of course, the exact calculations can be properly debated. Nevertheless, it is inarguable that both volcanic eruptions had a significant cooling effect on…
