Two new papers suggest solar activity is a ‘climate pacemaker’

      Here are some highlights of these two new papers published in Physics Letters A by David H. Douglass & Robert S.Knox: Central Pacific region temperature dataset SST3.4 from 1990 to 2014 is studied. SST3.4 contains a sustained signal at 1.0 cycle/yr implying solar forcing. SST3.4 also contains a signal (<1 cycle/yr) showing…

Splicing Clouds

Guest Post by Willis Eschenbach So once again, I have donned my Don Quijote armor and continued my quest for a ~11-year sunspot-related solar signal in some surface weather dataset. My plan for the quest has been simple. It is based on the fact that all of the phenomena commonly credited with affecting the temperature,…

Partial solar eclipse shows off massive sunspot

From the National Science Foundation: Press Release 14-141 Spotlighting the sun October 24, 2014 Astronomers with the National Science Foundation (NSF)-funded National Optical Astronomy Observatory (NOAO) captured pictures not only of Thursday’s partial solar eclipse, but also of the “monster” sized active region or sun spot that has many comparing it to one of a…

Changes in Total Solar Irradiance

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…

Sunspot-2192

Massive X class flare erupts from the sunspot 2192

As we previously mentioned on WUWT, the Sunspot 2192 which is as large as Jupiter had the potential of hurling large solar flares toward Earth. According to NASA’s spaceweather.com “Giant sunspot AR2192 has a ‘beta-gamma-delta’ magnetic field that harbors energy for strong explosions. NOAA forecasters estimate an 85% chance of M-class flares and a 45%…
