By Andy May This post is about an important new paper by Nicola Scafetta, Richard Willson, Jae Lee and Dong Wu (Scafetta, Willson and Lee, et al. 2019) on the ACRIM versus PMOD total solar irradiance (TSI) composite debate that has been raging for over 20 years. ACRIM stands for Active Cavity Radiometer Irradiance Monitor,…
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 Shaviv’s reply to this post, I have withdrawn any mention of “deceptive” from this post.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…
Total solar irradiance, also called “TSI”, is the total amount of energy coming from the sun at all frequencies. It is measured in watts per square metre (W/m2). Lots of folks claim that the small ~ 11-year variations in TSI are amplified by some unspecified mechanism, and thus these small changes in TSI make an…
Guest Post by Willis Eschenbach I was pointed to a 2010 post by Dr. Roy Spencer over at his always interesting blog. In it, he says that he can show a relationship between total solar irradiance (TSI) and the HadCRUT3 global surface temperature anomalies. TSI is the strength of the sun’s energy at a specified distance…
Guest Post by Willis Eschenbach Are there cycles in the sun and its associated electromagnetic phenomena? Assuredly. What are the lengths of the cycles? Well, there’s the question. In the process of writing my recent post about cyclomania, I came across a very interesting paper entitled “Correlation Between the Sunspot Number, the Total Solar Irradiance,…
Despite some small upticks on sunspot and 10.7cm radio activity, the magentic activity of the sun is still bumping along the bottom. A slight uptick was seen in sunspot count. A similar slight uptick occurred in radio flux.
On Saturday I posted about this study from Pierre Gosselin at No Tricks Zone: New Study Shows A Clear Millennial Solar Impact Throughout Holocene Now we have another that suggests little effect. and shows a business as usual projected warming trend. From the: JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, D05103, 13 PP., 2012 doi:10.1029/2011JD017013 What…
This is a repost from Lansner’s website, since Tamino aka Grant Foster won’t allow it to be discussed on his own website, I thought I’d give a forum for discussion here. – Anthony The real temperature trend given by Foster and Rahmstorf 2011?
