Frank Lansner on Foster and Rahmstorf 2011

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…

Are secular correlations between sunspots, geomagnetic activity, and global temperature significant?

New paper by Love et al suggests no prominent role for solar‐terrestrial interaction in global climate change. I’m providing it here for discussion. We are not convinced that the combination…

Hathaway's November Solar Prediction

By David Archibald Joe D’Aleo asked for my comments on NASA’s James Hathaway’s latest solar prediction, available here: http://solarscience.msfc.nasa.gov/predict.shtml When I read May 2013 for solar cycle maximum, I thought…

Solar and climate- no longer taboo

Paul Hudson of the BBC writes: This is an exciting time for solar physics, and its role in climate. As one leading climate scientist told me last month, it’s a…

Archibald: Solar Based Climate Forecast to 2050

Guest post by David Archibald When I started out in climate science in 2005, the climate people ignored the solar physics community. A casual perusal of the literature though indicated…

Study: solar activity lull increases chances of cold UK winters

From the Institute of Physics More than 1 in 10 chance of colder UK winters As the Sun enters a period of low solar activity over the next 50 years,…

Easterbrook on the potential demise of sunspots

THE DEMISE OF SUNSPOTS—DEEP COOLING AHEAD? Don J. Easterbrook, Professor of Geology, Western Washington University, Bellingham, WA The three studies released by NSO’s Solar Synoptic Network this week, predicting the…

"All three of these lines of research to point to the familiar sunspot cycle shutting down for a while."

I’ve managed to get a copy of the official press release provided by the Southwest Research Institute Planetary Science Directorate to MSM journalists, for today’s stunning AAS announcement and it…

"People underestimate the power of models. Observational evidence is not very useful."

Guest post by Alec Rawls Andrew Orlowski at the UK Register has an anecdotal account of Downing College’s skeptics-vs-believers mash-up. Ace of Spades pulled the juiciest bit: In short, the…

New solar reconstruction paper suggests 6x greater solar forcing change than cited by the IPCC

This is interesting. This recent paper published in the journal Astronomy & Astrophysics here has done a reconstruction of TSI using Beryllium 10 isotope records combined with sunspot records. The paper…

Solar warming and ocean equilibrium, Part 3: Solanki and Schuessler respond

Guest post by Alec Rawls Solar physicist Sami Solanki and his colleagues at Germany’s Max Planck Institute for Solar System Research helped pioneer the use of cosmogenic isotopes from ice…

New paleo paper shows solar impact on past temperatures

From C3 headlines – Scientists Say Norwegian Sea Research Confirms Large, Robust Solar Impact On Temperatures Read here. Map source here. (click on image to enlarge) There are multiple factors…

Does solar activity have to KEEP going up to cause warming? Mike Lockwood responds

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…
