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…
A quiet cue ball sun

Transit of Venus as seen in California
My lovely wife is snapping photos already, as it has just started. Here’s a sample.
Premonitions of the Fall (in temperature)
Guest post by David Archibald The first prediction of the current climatic minimum was made by Hubbert Lamb in 1970 in a report (Weiss and Lamb) for the German Navy.…
Annular Solar Eclipse 2012 – data and images
I’ve been asked to provide some information on the upcoming eclipse Sunday, so here it is. I’ll actually miss the first part of the Heartland conference (Sunday night and Monday)…
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…
Sunspot AR1476 takes aim on Earth
From Spaceweather.com NOAA forecasters estimate a 75% chance of M-class solar flares and a 20% chance of X-flares during the next 24 hours. Any eruptions are likely to be geoeffective…
Solar cycle update for April – sun still slumping
Got a bit sidetracked earlier in the month, this is overdue for an update. Earlier we reported that Hathaway had updated his solar cycle prediction saying “…the predicted size makes…
A Tale of Two Altitudes: how stratospheric temperature is de-coupled from the surface temperatures
On the battle between Arrhenius and Ångström. Story submitted by John Kehr, The Inconvenient Skeptic Any serious discussion about the Theory of Global Warming will eventually include the absorption band…
Paper: Russian Heat Wave of 2010 Linked to Solar Activity?
Just a quick note to bring this to attention of readers. I have not been able to locate a copy of this paper other than the paywalled one at Springerlink,…
Potential for large solar flares and CME's may be with us again soon
Readers may recall my reports on the CME’s from massive sunspot group 1429, seen below. It seems the sunspot group continues to live, and has unleashed another massive Coronal Mass…
Geomagnetic data reveal unusual nature of recent solar minimum
From the American Geophysical Union weekly highlights: Key Points Minimum 23-24 showed recurrence intervals of 9.0 and 6.7-d Historical geomagnetic activity data show that minimum 23-24 was unusual The heliosphere…
Recent solar flare seen bombarding Earth with gamma rays
From the “Oh noes it’s Radiation” department, Dr. Leif Svalgaard points out we all got a gamma ray bath on that recent big solar flare. I wonder how many Banana…
Solar storm continues, geomagnetic storm and auroras expected
We have about three hours to go for the expected arrival time of the CME at 0625 UTC/1025 PM PST. Proton flux remains high as do other indicators. Additionally another…
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…
GISS finally concedes a significant role for the sun in climate
UPDATE: The paper itself is available below. There is a new paper published yesterday in the journal Geophysical Research Letters from NASA GISS/Columbia University and Brown University titled Hydroclimate of…
The World won’t stop having climate cycles just because they are inconvenient.
Guest post by David Archibald The most skillful climatologist the World has seen was Hubert Lamb (1913 – 1997). He can be credited with making the first prediction of the…
Homeland Security takes on The Carrington Event
While we worry about future threats like global warming, and present threats like Iran’s escalating nuclear program, the sun’s propensity for belching out monstrous solar flares (like the Carrington event…
