A rebuttal to Steven Sherwood and the solar forcing pundits of the IPCC AR5 draft leak
Teaming up with Jo Nova to answer The Team down under: “Professor Sherwood is inverting the scientific method” Guest post by Alec Rawls My leak of the draft IPCC report…
Isaac Held's 2-box model: another failed ocean-equilibration excuse for dismissing solar warming
Guest post by Alec Rawls Dr. Isaac Held, who models fluid dynamics at NOAA, dismisses a solar explanation for late 20th century warming by invoking a 2-box model of ocean…
Solar Activity – Past, Present, Future
Essay/paper by Dr. Leif Svalgaard Abstract As our civilization depends increasingly on space-borne assets and on a delicate and vulnerable earth-bound infrastructure, solar activity and its potential impact becomes of…
Is there a planetary influence on solar activity? It seems so according to this new paper
Guest post by David Archibald Long suspected, it seems that this has now been confirmed by a paper in Astronomy and Astrophysics with the title “Is there a planetary…
Muscheler retracts? Offers a NEW excuse for why solar activity can't be responsible for post-70's warming
Guest post by Alec Rawls Technically Dr. Muscheler is asking me to retract the title of my post, “Raimund Muscheler says that a steady high level of forcing can’t cause warming“:…
Raimund Muscheler says that a steady high level of forcing can't cause warming
Guest post by Alec Rawls Solar warming and ocean equilibrium, part 4 I emailed Dr. Muscheler about the very strange remarks that were attributed to him in the recently released…
Paper demonstrates solar activity was at a grand maximum in the late 20th century
Solar activity measured by isotope proxies revealed the end of 20th century was the highest activity in 1200 years A 2010 paper (that I somehow missed) was recently highlighted by…
Another regime change indication – this time in solar data
Note: See also the 1997 regime change in global climate data by the same method, here I’m happy to report that something I recognized and reported back in 2008 related…
The Sun has changed its character
Guest post by David Archibald A number of solar parameters are weak, and none is weaker than the Ap Index: Figure 1: Ap Index 1932 to 2026 Figure 1 shows…
NASA June 2012 Solar Cycle 24 Prediction
Compiled by Joe D’aleo WeatherBell via NASA MSFC The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 60 in the Spring of 2013. We…
Another day, another Central Asian precipitation study finds a link to solar activity
From Sun and Liu 2012: all of the deep solar minima of the last millennium (Oort, Wolf, Spörer, Maunder and Dalton) correspond to periods of drought in the Qilian Mountains…
Solar grand minima linked to cooling period in Europe
This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800…
NASA/Hathaway's updated solar cycle prediction – smallest in 100 years
…the predicted size makes this the smallest sunspot cycle in about 100 years (Updated 2012/05/01) From: http://solarscience.msfc.nasa.gov/predict.shtml The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum…
From Schmidt 2005 to Miller 2012: the "not needed" excuse for omitted variable fraud
Guest post by Alec Rawls Miller et al. 2012 recently provided some pretty strong evidence for a solar driver of climate. “This is the first time anyone has clearly identified…
Back-testing the Solar – Sea Level Relationship
Guest post by David Archibald This is a little bit amusing. In February, I had a post on the solar – sea level relationship which quantified the sea level fall…
Scafetta's new paper attempts to link climate cycles to planetary motion
Nicola Scafetta sent me this paper yesterday, and I read it with interest, but I have a number of reservations about it, not the least of which is that it…
Talking about the weather
Harold Ambler needs a bit of a boost, his book Don’t sell your coat is the American equivalent of Ian Plimers book How to get expelled from school in Australia,…
Another solar study: this one suggests no significant solar influence
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…
