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…

Aurora Borealis and surface temperature cycles linked

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.…

Warming on 11 year hiatus? How about cooling?

A guest post by Basil Copeland Lucia, at rankexploits.com, has been musing over Tilo Reber’s posting of a graph showing flat 11 year trends in the HadCRUT land-ocean global temperature…

I'm considering a blog policy change

Preparing to launch a “flame”. A couple of things have happened this week that has made me look at this blog just a bit differently than in the past. I’ve had to…

The pause that cools: No more warming until 2015?

You may recall the previous post where Basil Copeland and I looked at correlations between HadCRUT global temperature anomaly and sunspot numbers. This is similar, but looks at the Pacific…

Seeing the Wood for the Trees: Interactive climate analysis for everyone

In America we have a saying, “Seeing the forest for the trees…” which is used to suggest seeing the bigger picture. In Britain, the similar saying is “Seeing the wood…
