The 60-year oscillation revisited

Guest Post by Javier It is a well-known feature of climate change that since 1850 multiple climate datasets present a ~ 60-year oscillation. I recently wrote about it in the 7th chapter of my Nature Unbound series. This oscillation is present in the Atlantic Multidecadal Oscillation (AMO), Arctic Oscillation (AO), North Atlantic Oscillation (NAO), Pacific…

Aurora Borealis and surface temperature cycles linked

Dr. Roger Pielke Sr. writes about a new paper from Nicola Scafetta.: New Paper “A Shared Frequency Set Between The Historical Mid-Latitude Aurora Records And The Global Surface Temperature” By N. Scafetta 2011 A new paper has just appeared Nicola Scafetta 2011: A shared frequency set between the historical mid-latitude aurora records and the global surface…

New Scafetta paper – his celestial model outperforms GISS

Dr. Nicola Scafetta writes: Anthony,   I believe that you may be interested in my last published work. This paper suggests that climate is characterized by oscillations that are predictable. These oscillations appear to be linked to planetary motion. A climate model capable of reproducing these oscillation would outperform traditional climate models to reconstruct climate oscillations.…

What Do We Really Know About Climate Change?

A Guest Post by Basil Copeland Like many of Anthony’s readers here on WUWT, I’ve been riveted by all the revelations and ongoing discussion and analysis of the CRUtape Letters™ (with appropriate props to WUWT’s “ctm”). It might be hard to imagine that anyone could add to what has already been said, but I am…

Is Global Temperature a Random Walk?

Guest Post by Basil Copeland Figure 1 Each month, readers here at Watt’s Up With That, over at lucia’s The Blackboard, and elsewhere, anxiously await the latest global temperature estimates, as if just one more month of data will determine one way or the other the eternal destiny of AGW (the theory of “anthropogenic global…

New paper – Global dimming and brightening: A review

Global dimming and brightening: A review Martin Wild Institute for Atmospheric and Climate Science, ETH Zurich, Zurich, Switzerland There is increasing evidence that the amount of solar radiation incident at the Earth’s surface is not stable over the years but undergoes significant decadal variations. Here I review the evidence for these changes, their magnitude, their…
