In July last year three climate scientists published a paper in the Journal of Geophysical Research. “Influence of the Southern Oscillation on tropospheric temperature” concluded that nature, not man, was responsible for “recent global warming.”
The paper, by John McClean, Chris DeFreitas and Bob Carter, shows that what the SOI does now, the temperature will do in between five and eight months’ time.
Simple. But does it work to predict global temperatures? Continue Reading →
