Sunspot count is virtually unchanged from last month :

It seems possible that we’ve seen the double peak, and it will be downhill after this.
A similar status quo in radio flux – little change from last month.

The Ap magnetic index dropped 4 units from last month, suggesting a slowing in the solar dynamo.

On August 1st, solar scientist David Hathaway updated his prediction page but the text is identical to last month – no change in the forecast.
The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 67 in the Summer of 2013. The smoothed sunspot number has already reached 67 (in February 2012) due to the strong peak in late 2011 so the official maximum will be at least this high. The smoothed sunspot number has been rising again over the last four months. We are currently over four years into Cycle 24. The current predicted and observed size makes this the smallest sunspot cycle since Cycle 14 which had a maximum of 64.2 in February of 1906.
About the only significant even in the last month is that the solar polar fields have begun their reversal, indicating we are at “solar max”, which seems like a misnomer given the low activity observed at the moment. That’s why I think we may have seen the “double peak” and it is downhill from here.

Updated correlation for the evolution of the sun’s magnetic Polar Fields calculates at R^2=0.915
It is not correct to omit MWO as their data is good back to at least 1970 [following an upgrade of the instrument], as you can see from the close relationship with WSO when they overlap: slide 20 of http://www.leif.org/research/On-Becoming-a-Scientist.pdf

“I devised a formula, extrapolating to the unusually low solar activity in the late 2020s
http://www.vukcevic.talktalk.net/LFC2.htm
which is now widely accepted as a likely scenario”
No it is not, as your ‘formula’ predicts that the solar polar fields will not reverse in the next cycle. That is not accepted by anybody.
Hi doc
That remains to be seen, maybe or maybe not, anyway as you correctly quoted I said:
….” extrapolating to the unusually low solar activity in the late 2020s” which indeed is now widely accepted as a likely scenario, I didn’t say anything about the PF reversal, but if it did not occur I would be first one to be surprised by the accuracy of the extrapolation.
Now you mentioned it, I intend to put away one bottle champaign and one bottle of French plonk 2003 vintage, just in case. Both will be consumed with pleasure in the memory of my folly or otherwise, around 2024/5 whatever the sun and its polar fields do.
This is all done for fun, I leave the serious stuff to Dr. Hathaway and good yourself.
Cheers.

“Also, TSI, that is, the relatively low energy electromagnetic energy, probably is not the primary energy to look at when the sun’s influence on climate is attempted to be quantified. High energy waves are by and large neglected, as well as the high energy particles in the solar wind, e.g. neutrinos and protons, …”
The “T” in TSI stands for “total”, so accounts for _all_ of the electromagnetic radiation (EMR) energy radiated by the Sun (from low-frequency RF up to X-ray and gamma radiation). Most of this EMR is in the visible light spectrum and nearby IR and UV bands, according to its black-body temperature (~5800K) and the Planck distribution:
http://en.wikipedia.org/wiki/Planck's_law
Yes, this is mathematic model, but solar EMR observations fit the model very well.
The most reliable TSI measurements are made by the orbiting NASA SORCE/TIM instrument, which measures temperature changes caused capturing all solar radiation impinging on its ‘sensor’. The ‘sensor’ is actually a small aperture on the surface of an insulated calorimeter chamber. Because the diameter of the hole is relatively small compared to the size of the chamber, virtually all of the admitted EMR is absorbed by chamber and converted to heat, i.e. simulating an ideal black-body which, by definition, absorbs all incoming radiation.
http://glory.giss.nasa.gov/tim/
Because of this precise design, SORCE/TIM has changed the ‘consensus’ estimate of 1366 w/m^2 for TSI at TOA. It is now estimated at 1362 w/m^2 due to the greater precision of TIM’s aperture:
http://spot.colorado.edu/~koppg/TSI/#mission_highlights
Energy radiated by other forms of solar energy, e.g. particles is a small fraction of the solar EMR solar output. For example, solar neutrinos constitute 3% of total solar energy. But neutrinos barely interact with other forms of matter and so do not get absorbed by the atmosphere or Earth’s surface.

It does not remain to be seen whether your ‘prediction’ of no reversal is accepted. It simply is not.
I didn’t say anything about the PF reversal
Your ‘formula’ does. The sign is a large part of the correlation. Here you can see the effect of correlating 200 random number with their ordinal number. The first 100 are made negative. You get a hefty [and generally considered valid] correlation. Remove the sign and there is no correlation [the numbers are random]. So, in order to evaluate your correlation use MWO back to 1970 [the comined MWO+WSO series] and remove the sign [if you say that the sign does not matter]. Anything else is just junky ‘fun’ as you call it.

Reality check. Solar-anything driving weather pattern variation is easily refuted. A strong El Nino (which actually spits out heat from the oceans, thus cooling them) can warm things up on land in the face of a weak solar cycle. Therefore Oceanic conditions are more powerful than solar affects…..
>>>>>>>>>>>>>>>>
Pam, you haven’t followed that back to where that strong El Nino comes from. The Drakes Passage constricts the Antarctic Circumpolar Current and shoots some of the cold Antarctic water up the coast of South America where El Nino/La Nina originates. The Antarctic Circumpolar Current is driven by wind.
These winds are then connected to ozone:
Decadal Changes of Wind Stress over the Southern Ocean Associated with Antarctic Ozone Depletion
Ozone Thinning Has Changed Ocean Circulation “Jan. 31, 2013 — A hole in the Antarctic ozone layer has changed the way that waters in the southern oceans mix,… In a paper published in this week’s issue of the journal Science, Darryn W. Waugh and his team show that subtropical intermediate waters in the southern oceans have become “younger” as the upwelling, circumpolar waters have gotten “older” — changes that are consistent with the fact that surface winds have strengthened as the ozone layer has thinned. “
This is just a glimpse of other possibilities.

Energy radiated by other forms of solar energy, e.g. particles is a small fraction of the solar EMR solar output.
Indeed, the total energy of the solar wind, cosmic rays, and solar energetic particles is less than 1/100th of a W/m2.

Looking back at annualized growth in federal spending, the biggest spender was Ronald Reagan (8.7%) followed closely by Bush II (8.1%), Bush I (5.4%), and Bill Clinton (3.2%). As a matter of fact, even Clinton’s low of 3.2% federal spending growth is nearly two-and-a-half times higher than President Obama’s 1.4% during his first term in office.
http://m.whitehouse.gov/omb/budget/Historicals
One simple fact Republicans understand, but many in the population do not, is that the first year of every presidential term starts with a previous administration’s budget approved by Congress. Republicans began their lying by counting 2009′s fiscal year budget as the President’s even though it began four months before he moved into the White House, and included spending increases of hundreds of billions of dollars in response to Bush-Republicans’ economic and financial catastrophe. In the 2009 fiscal year budget, the last of George W. Bush’s presidency, federal spending rose by 17.9% from $2.98 trillion to $3.52 trillion, and the first budget attributable to President Obama (fiscal 2010), spending fell 1.8% to $3.46 trillion. In fiscal 2013, the final budget of the President’s first term, spending is scheduled to fall 1.3% to $3.58 trillion according to the non-partisan Congressional Budget Office (CBO), and extended out means that over the President’s first four budget years, federal spending is on track to rise from $3.52 trillion to $3.58 trillion, an annualized increase of just 0.4%. Obviously, there has been no huge increase in spending under President Obama, and yet Republicans claim he has been on a spending binge that is the sole cause of the nation’s economic woes.
http://www.cbo.gov/publication/42905
The utter failure of Republicans is acknowledging that President Obama is stingy with federal dollars, and that their spending cut propensity is directly correlated to which party is in the White House. Republicans had no problem blowing up the deficit when Bush II was in the White House, and most Americans are unaware that Bush’s folly in Iraq and Afghanistan were kept out of the budget and still old George and Republicans presided over the second highest federal spending increase since Reagan was president. President Obama gave Republicans a good offer to avoid the dreaded fiscal cliff that included over $800 billion in spending cuts they hardly considered adequate because in their world view, one can never cut enough from services and safety nets.
It is a hard pill for Republicans to swallow, but this President has reduced spending to the point that there is little left to cut without causing more undue harm to tens-of-millions of Americans. However, one must remember that causing harm to the poor, children, Veterans, and seniors is the prime directive of Republicans and their policy machine the Heritage Foundation, and regardless that President Obama leads the pack in reducing spending, Republicans and Heritage will always find more ways to punish Americans whether it is robbing them of their Social Security retirement accounts, cutting food stamps, cutting healthcare spending, slashing Veterans benefits, or eliminating school lunch programs that not only reduces spending, it reduces life expectancy.
1) Conservatives opposed the American Revolution
Conservatives vehemently warned us that it was unnatural to rebel to our Sovereign Lord, King George III, and that doing so would plunge the colonies into disorder. They assured us, as the father of Conservatism, Edmund Burke echoed, that social stability would only come from the small group of wealthy aristocrats ruling over the poor majority. Conservatives reiterated that it was the duty of the poor to obey their “betters.” Their rewards, after all, will come in Heaven.
2) Conservatives opposed freeing the slaves
It is interesting to note that, in 1860, the Democrats were the real conservatives, while the Republicans were the left-leaning radicals.
Lincoln believed that rich Americans should pay more than their less wealthy friends and neighbors.
But, because they are CONS and want to rig the system in their favor, they only considered slaves “people” for purposes of counting them in order to increase the slave-state representation in Congress.
Conservatives warned that freeing the slaves, believe it or not, was an affront to liberty – as well as an evil government plot to force hardworking business owners to release their property. After all, as the Bible tells us, and as Rush Limbaugh later reminded us, “some people are just born to be slaves.”
3) Conservatives opposed women’s suffrage
4) Conservatives opposed minimum wage and child labor laws, the 8-hour work day, weekends, sick leave… etc.
5) Conservatives opposed humane treatment of animals
6) Conservatives opposed the Social Security Act
7) Conservatives oppose clean air and water
8 ) Conservatives opposed the Civil Right’s Act
9) Conservatives opposed Medicare
10) Conservatives oppose Equal Protection Under the Law
The Stefan-Boltzmann radiation law states that radiation depends on the fourth power of temperature, from which is follows that a 0.1% change in radiation corresponds to a change in temperature of one quarter of that, so your 0.28C should be 0.07C.

What has always bothered me about your focus soley on TSI is related to the ultraviolet variations. If, as the AGW hypothesis suggests, that a minor atmospheric trace gas can effect temperatures so much due to the resonant coupling of the absorption/emission spectra with those molecules bandgap energy, why then can’t the strong couplings with oxygen in the ultraviolet spectrum not have a similar effect? Thus if those wavelengths are suppressed with cycle variances that we know are there, which can easily be seen in exoatmospheric density variations, why can’t are hypotheses related to this well known and tested by data phenomenon dismissed?
We also see evidence for the eleven year and other cycles of the sun’s output in many many climate proxies, thus there must be something missing in this focus simply on TSI.
Nigel, it really IS an increase of only 0.00012 (0.012%) of the atmosphere.
Making percentages of tiny numbers vs other tiny numbers in order to make the comparator look bigger is an old propaganda trick.

…………….
It is exactly what happened at the time of the Dalton Minimum if transposed to the Polar Fields few years earlier
http://www.vukcevic.talktalk.net/PF.htm
Thanks for the challenge.
. Let’s review what happened during low sunspot or lower solar flux activity according to historical CET temperature records. I seriously question the claim of only 0.1C drop due to the sun during solar minimums .
Record CET Coldest winter temperatures during major solar minimums
19 of the 30 coldest annual CET temperatures were during the three very low sunspot periods of Maunder Minimum. Dalton Minimum and the Modern Minimum of 1880-1910
20 of the 30 coldest winter CET temperatures were during the same three major minimums, regular minimums, or sustained low solar sunspot years
During Maunder minimum and looking at CET temperature data 1645-1715
The period 1690-1699, the coldest decade, had an average annual temperature of 8.107C. The average annual decade temperature during 1981-2010 was 9.9 C. The annual average temperature 1940-1979 [the era before global warming was 9.48C] The annual average temperature shortly after MM, namely 1720-1729 was 9.3 C and 1730-1739 was 9.8 C. So on an annual basis the temperatures dropped about 1.2 -1.7C during MM
During Dalton Minimum [1790-1720
The same analysis of the period 1807-1816 during the Dalton Minimum shows annual temperatures of about 8.6C when annual sunspot number was zero during 1810. The winter of 1814 was the 4th coldest in CET records at – 2.9 C again -5.3C colder than 2010
During other low solar activity periods
If we further check the record, global temperatures tend to drop near the end of long solar cycles and at the beginning of the next decade. One can see the global temperatures decline at the end of cycles # 9, 13, 14, and 20.
If we also check the impact on Northern Hemisphere winter temperatures as measured by Hadcrutgl3, the temperatures drops for 3-4 years around each of the last 3 solar minimums or whenever the solar flux F 10.7 level drops to between 100 and 70 [ unless there happens to be an El Nino during the same years] Just check the years 2009, 2010 2011
CET Winter temperatures dropped at the solar minimum year or the years before or after for 30 of the last 31 solar minimums.
Thus we note that these historical temperature drops during low solar activity are significantly more than -0.1 C when looking at winter temperatures
If the sun is not somehow involved in these changes , the so called “other climate factors “ must have a very smart calendar to come on and off each time the sun drops to a certain threshold after a sustained and declining period of about 5-10 years .

Why not ask Ilya Usoskin or Kalevi Mursula? Cycle 4a lasted only 3 years
A bit of honesty would do you good. If you would care to check, they say 7 years. And their 4a cycle has already been discredited and gone the way of the Dodo, e.g. http://www.mps.mpg.de/homes/natalie/PAPERS/cycle4.pdf “Taken together, the evidence from these various tests strongly suggests that no cycle was missed and that the official sunspot cycle numbering and parameters are correct”
But back to the issue. You predict that the maximum of cycle 26 will occur only two years after the maximum of cycle 25. so when will the minimum be? halfway between the two maxima? in 2024? that gives SC25 only one year to descend from maximum to minimum. You are stretching things a bit too much here. But such is the lot of a pseudo-scientist. Sooner or later, reality catches up with him. Most of the time he will ignore that and invent so excuse. What will be yours?
On to 25, to the extent it will exist at all.

Ed,
I agree with almost all the above, but most of the younger conservatives here are probably not aware of the above history, and it’s unfair to paint them with the same brush as former generation conservatives. I’m one of those center left- I prefer that term- luke warmers who is very upset by the liberal establishment’s groupthink and uncritical embrace of CAGW, but equally upset by much of the right wing groupthink and uncritical embrace of conspiracy theories about liberal CAGW motivations. The belief we know other’s motivations is like the belief we know the future of global warming and cooling- self satisfying, but unhelpful.

What has always bothered me about your focus soley on TSI is related to the ultraviolet variations.
UV variations follow TSI and the sunspot number generally. TSI is where the energy is and is where everybody [e.g. Jack Eddy] thought the influence would come from up until we found that TSI does not vary enough. Then other mechanisms [UV, feedback, unspecified ‘amplifications’, ‘unknown processes, magic, etc] were invented instead of following standard scientific practice when dealing with data not matching expectations.
We also see evidence for the eleven year and other cycles of the sun’s output in many many climate proxies, thus there must be something missing in this focus simply on TSI.
TSI is only an indicator for all the other solar outputs. They vary to first order like TSI [or perhaps it is TSI that is the result of all the rest – doesn’t matter]. The so-called evidence is weak and unconvincing, otherwise there would be no debate. All correlations I have seen over the past 40 years I have studied this problem have failed in one way or other, perhaps you can show me one that have worked having error bars and significance [and sound analysis – e.g. no cherry picking] that is compelling.
Why is my comment awaiting moderation for the first time since in months? WUWT?
