Is The Signal Detectable?

Guest Post by Willis Eschenbach [UPDATE] In the comments, Nick Stokes pointed out that although I thought that Dr. Shaviv’s harmonic solar component was a 12.6 year sine wave with a standard deviation of 1.7 centimetres, it is actually a 12.6 year sine wave with a standard deviation of 1.7 millimetres (5 mm peak to…

The Missing ~ 11-Year Signal

Guest Post by Willis Eschenbach Dr. Nir Shaviv and others strongly believe that there is an ~ 11-year solar signal visible in the sea level height data. I don’t think such a signal is visible. So I decided to look for it another way, one I’d not seen used before. One of the more sensitive…

The New Sunspot Data … and Satellite Sea Levels

Guest Post by Willis Eschenbach [UPDATE: Upon reading Dr. Shaviv’s reply to this post, I have withdrawn any mention of “deceptive” from this post. This term was over the top, as it ascribed motive to the authors. I have replaced the term with “misleading”. This is more accurate since it describes the effect of the analysis…

Dr. Trenberth Redux

Guest Post by Willis Eschenbach A couple days ago, I was given a copy of a most interesting interchange from 2011 between Dr. Kevin Trenberth and a layman asking him a question. The sender of the question recently passed it on to me. I’ve redacted the email addresses and the name of the person asking the question,…

The Sea Level Cycles Get More Elusive

Guest Post by Willis Eschenbach In my last post on the purported existence of the elusive ~60-year cycle in sea levels as claimed in the recent paper “Is there a 60-year oscillation in global mean sea level?”, I used a tool called “periodicity analysis” (discussed here) to investigate cycles in the sea level. However, some people…

The Elusive ~ 60-year Sea Level Cycle

Guest Post by Willis Eschenbach I was referred to a paywalled paper called “Is there a 60-year oscillation in global mean sea level?”  The authors’ answer to the eponymous question is “yes”, in fact, their answer boils down to “dangbetcha fer sure yes there is a 60-year oscillation”, viz: We examine long tide gauge records…
