There goes that “scientific consensus” about AGW again. And in a peer-reviewed study too.
Three Australasian scientists have published a study in the Journal of Geophysical Research claiming that virtually none of the observed temperature increases in the Earth’s atmosphere in recent years can be attributed to man-made factors.
Ummm … sure am wantin’ me some of that cap-and-trade now. As anyone should be able to figure out by now, the science is anything but settled concerning AGW.
Their research says that it is the El Nino-Southern Oscillation that pretty much has its way with temperature. And, the claim, volcanoes have a pretty significant impact on cooling.
“The surge in global temperatures since 1977 can be attributed to a 1976 climate shift in the Pacific Ocean that made warming El Niño conditions more likely than they were over the previous 30 years and cooling La Niña conditions less likely” de Freitas said.
“We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century. It may even be more if the period of influence of major volcanoes can be more clearly identified and the corresponding data excluded from the analysis,” he added.
“Overall the results suggest that the Southern Oscillation exercises a consistently dominant influence on mean global temperature, with a maximum effect in the tropics, except for periods when equatorial volcanism causes ad hoc cooling.”
Not so much.
I’m sure our resident AGW believers will troop in to tell us how this is obviously not anything that “real science” would advance – except this is real science, with real scientists and a peer-reviewed study.
