Guest post by Alec Rawls My first post on this subject remarked on the number of scientists who assert that late 20th century global warming cannot have been driven by…

The minimal solar activity in 2008–2009 and its implications for long‐term climate modeling
This is a new paper in Geophysical Research Letters by C. J. Schrijver, W. C. Livingston, T. N. Woods, and R. A. Mewaldt. WUWT readers may recognize Livingston as the…
Normal Seasons of the Sun (GW Tiger)
Guest post by Ira Glickstein PhD. We had joy, we had fun, we had Seasons of the Sun. But the mountains we climbed were but whimsies of our minds. That…
New paper on forcings of historical European temperatures
From Nature Geoscience Influence of human and natural forcing on European seasonal temperatures Gabriele Hegerl, Juerg Luterbacher, Fidel González-Rouco, Simon F. B. Tett, Thomas Crowley & Elena Xoplaki Journal name:…
New Total Solar Irradiation (TSI) baseline value – solar min measured lower in 2008
From a new paper by Dr. Greg Kopp and Dr. Judith Lean, new finding on the solar minimum TSI in 2008: The most probable value of total solar irradiance representative…
The sun is still in a slump – still not conforming to NOAA "consensus" forecasts
NOAA’s Space Weather Prediction Center (SWPC) produced their monthly solar cycle progression update yesterday. The news is not encouraging. We’ve had a drop in solar activity again in December, The…
Do solar scientists STILL think that recent warming is too large to explain by solar activity?
Guest post by Alec Rawls Study of the sun-climate link was energized in 1991 by Friis-Christensen and Lassen, who showed a strong correlation between solar-cycle length and global temperature: This…
Solar Geomagnetic Ap Index Hits Zero
This is something you really don’t expect to see this far into solar cycle 24. But there it is, the Solar Dynamics Observatory satellite shows the sun as a cueball:…
Confirmation of Solar forcing of the semi-annual variation of length-of-day
This essay by Paul Vaughn is very interesting because it shows correlation between cosmic rays (via neutron count), terrestrial angular momentum, and length of day. – Anthony Semi-Annual Solar-Terrestrial Power…
A Dalton Minimum Repeat is Shaping Up
The sun went spotless yesterday, the first time in quite awhile. It seems like a good time to present this analysis from my friend David Archibald. For those not familiar…
