Nicola Scafetta and Richard Willson have a new paper in press which contains the most thorough analysis yet of the intercomparison of the empirical ACRIM and modeled PMOD TSI series. It’s a comprehensive yet readable paper of high interest to all diligent climate researchers interested in determining the relative strengths of various climate drivers. It is […]

Nicola Scafetta has reminded me to revisit his global average surface temperature (GST) forecast (Cyan area), which he derived from a simple phenomenological model using solar system planetary frequencies at the start of 2012. It is clearly much more accurate than the IPCC projection from 2000 (shown in Green on the figure below). See below […]

Congratulations to Nicola Scafetta  and Richard Willson on the publication of their new paper, made freely available by high impact journal Pattern Recognition in Physics : Multiscale comparative spectral analysis of satellite total solar irradiance measurements from 2003 to 2013 reveals a planetary modulation of solar activity and its nonlinear dependence on the 11 yr […]

Dr Nicola Scafetta has asked for assistance from the talkshop to disseminate a talk he has given at the John Locke Foundation recently. We are very happy to oblige. Video below the break. The John Locke Foundation introduces the video with this text: Nicola Scafetta is a research scientist at the Active Cavity Radiometer Solar […]

Congratulations to Dr Nicola Scafetta, who has just had another major paper published in the high-impact journal Earth-Science Reviews. In email, Nicola tells me: This paper contains a detailed analysis of all CMIP5 models used by the IPCC, and demonstrates that they do not well reproduce the decadal and multidecadal patterns since 1850 (not just […]

This is a low interest informal article, I’ll chat, where it is easier to do as a new article than as a huge comment to an existing article. I’ve been taking a close look at some of the TSI data to see what I can find. Other matters need my attention so I am wrapping […]

My Thanks to Nicola Scafetta for alerting us to his new paper co-authored with Richard Willson. The introductory section has a good condensed history of the solar-planetary theory worth a post in its own right really. But the meat of the paper deals with exciting new findings, including a finer resolution examination of the z-axis […]

Congratulations to Nicola Scafetta, who has successfully published a new paper on sea level rise Multi-scale dynamical analysis (MSDA) of sea level recordsversus PDO, AMO, and NAO indexes in the  journal Climate Dynamics. This is a major paper, which undertakes a comprehensive review of recent studies, which diverge widely in their findings. He finds that the main […]

Congratulations! to Nicola Scafetta and Richard C Willson on the publication of their new paper: Planetary harmonics in the historical Hungarian aurora record (1523–1960). This is another excellent paper, published in Planetary and Space Science. Grabbitquick before I take it offline. Scafetta always makes papers available later if you miss this one. The Hungarian record goes back […]
