UPDATED AGAIN #4 — Now with Vukcevics Hale cycle graph of Echuca. and #3 David Archibalds suggestion of the Hale Cycle at work. #2 with Willis Eschenbach’s graph and my thoughts, (see below)
Ian Bryce sent me a striking graph (or two). Looking at the original raw data from Echuca Victoria shows a dramatic cooling trend of nearly half a degree since 1900, and rather than being a siting anomaly, it’s repeated in two towns about 100km away.
Curiously he also finds peaks in the maximums at Echuca that look for all the world like they match the solar cycle. Is it a fluke, or could it be real? If it’s real, what conditions make the solar sun-spot cycle so apparent in Echuca — where its maximum temperatures seemingly peak with each second solar cycle. Can anyone find this signal in other places? — Jo
The area is inland Northern Victoria
Has there been Global Warming or Global Cooling in Echuca
