New insights into the solar magnetic dynamo

From NASA/GODDARD SPACE FLIGHT CENTER NASA: Understanding the magnetic sun The surface of the sun writhes and dances. Far from the still, whitish-yellow disk it appears to be from the ground, the sun sports twisting, towering loops and swirling cyclones that reach into the solar upper atmosphere, the million-degree corona – but these cannot be…

Amazon River Flow Data 1902 2014

Noise Assisted Data Analysis

Guest Post by Willis Eschenbach Once again, Dr. Curry’s “Week in Review-Science and Technology” doesn’t disappoint. I find the following: Evidence of a decadal solar signal in the Amazon River: 1903 to 2013 [link]  by Antico and Torres So I go to the link, and I find the abstract: Abstract It has been shown that…

A Dalton-like Amplitude for Solar Cycle 25

Guest essay by David Archibald The most accurate method for predicting the amplitude of the next solar cycle is to use the strength of the solar polar magnetic fields at solar minimum. But with solar minimum likely to be three years away, who can wait that long? The strength of the solar polar magnetic fields…

A Short Summary of Soon, Connolly and Connolly, 2015; “Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th Century”

Guest essay by Andy May Soon, Connolly and Connolly (2015) is an excellent paper (pay walled, for the authors preprint, go here) that casts some doubt about two critical IPCC AR5 statements, quoted below: The IPCC, 2013 report page 16: “Equilibrium climate sensitivity is likely in the range 1.5°C to 4.5°C (high confidence), extremely unlikely…

Solar Update October 2015

Guest essay by David Archibald Introduction While Solar Cycle 24 is well into its decline in terms of F10.7 flux and sunspot number, several types of solar activity have risen dramatically over 2015. The solar wind flow pressure, for example, is now at a two decade high. That in turn means that the low in…
