The current cycle of the sun is taking a long time to start, triggering different explanations, writes Mark Lawson in an article entitled: ‘Scientists disagree over lack of sunspots,’ published in the Australian Financial Review (subscription required).
Excerpt: Despite being dismissed by a number of scientists as of little consequence to the present discussion of climate change, the issue of the sun’s activity – or apparent lack of it – has been the subject of considerable debate in recent months. Scientists who concern themselves with the fledgling subject of space weather (changes in the sun’s emissions) have been wondering where all the sunspots have gone, when they might come back and what effect this will have on climate…..
Another scientist who says he has identified a link between the sun’s activity and climate – in particular between rainfall in Australia and sunspots – is Robert Baker, an associate professor at the University of New England’s School of Human and Environmental Studies. Baker tells the AFR he has identified a strong correlation between sunspots, the sun’s magnetic activity and the Southern Oscillation Index (SOI). He says variations in the earth’s magnetic field account for about half of the variation in the SOI, and that changes in sunspot activity as an indicator of magnetic activity can be correlated with rainfall patterns in south-east Australia . The Bureau of Meteorology has rejected Baker’s reasoning and a paper by him was not accepted by the Australian Meterological Magazine. But Baker says his analysis has been accepted by the peer-reviewed journal Solar Terrestrial Physics for publication in December.
J.Hansford. says
Well, a correlation is not cause…. But I tell you what, It’s a far better one than CO2 and Temperature at the moment.
10 year flatline in Temperature despite a 5% increase in CO2….. Oppsies. Probably time for the AGW mob to “adjust” the data again… eh?
Gary Gulrud says
“Despite being dismissed by a number of scientists as of little consequence to the present discussion of climate change, the issue of the sun’s activity – or apparent lack of it – has been the subject of considerable debate in recent months.”
The relationship between funding and position on solar inactivity is under-examined to date in the media.
Most predictions by ‘Heliophysicists’ included in symposia rely on statistical measures of recent Schwabe cycles re: their maximum sunspot numbers.
In fact, the correlation between sunspot number and other measures of solar activity, e.g., 10 cm radio flux, or geomagnetic indicies, or solar flaring is not strong in terms of physical phenomena.
These scientists are attempting to limit the discussion to predictions they can provide without reference to their utility and in turn maximize their income stream.
Unfortunately, the sun is frustrating their concerted efforts and brinkmanship is now their sole consolation as all of Western science has missed the mark.
Barry Moore says
The suns effect on our climate is very complex and has both short term effects which are not to difficult to spot but there are also delayed effects which are much more difficult to identify.
There is a very good website, woodfortrees.org which is an excellent source of unbiased data. Reference this web site, it can be seen that the TSI from peak to minimum of a normal sunspot cycle is in the order of 0.1 to 0.15% of the 1366 watts/m2. this may not seem much but when you consider the earth is warmed about 260 deg K by the sun 0.1% is 0.25 deg C which is very significant. Now add to this the solar wind effect which impacts the cosmic ray muon flux density thus impacting the lower cloud density and the influence of the sun can not be considered insignificant. Whether or not the suns magnetic field oscillations which appear to be related to the sunspot activity have any effect on our ocean currents is I think totally unknown but it is possible.
The NOAA Boulder sun spot web site has just released the July sunspot numbers and I think at 0.5 for the month a new record low has been established so we may see a long delay to the start of cycle 24 which should produce some very interesting data for the sun spot watchers. Lets just hope we are not entering another Maunder minimum, albeit this would blow the IPCC totally away but the negative effect of such a cold spell would be disastrous for the world’s agriculture.
Richard111 says
Summer, which hasn’t happened yet, Autumn which seems to be on us now, Winter which I am dreading this year, Spring I hope will warm us up a bit.
Otherwise our familiar seasons. Temperature changes of 15, 20, 25 degrees C over a period of a few short months. Crops not growing in Winter. Water running short in Summer. All very normal. Been going on for more than 60 years to my belief.
What is so exciting about a possible 1 degree C increase in temperature per century?
KuhnKat says
Barry,
you need to include the effects of the orbital anomaly of the earth. The top of atmosphere intensity varies over a range of about 100 yearly. Whether the higher intensity is on the northern or southern hemisphere may make a difference as the energy will be absorbed more efficiently by the ocean. Currently TSI max is during southern hemisphere summer and minimum during northern hemisphere summer.
Here is a link to the TSI data from SORCE:
http://lasp.colorado.edu/sorce/tsi_data/daily/SORCE_L3_TSI_DM_V0008_20030225_20080812.txt
You will notice that they give 2 sets of measurements, one for 1 AU and one for Earth Distance. It is thought provoking.
Barry Moore says
Thanks for the info I have saved that website and it will need some study.
Another thought just popped into my mind, I read an article recently about the gravitational pull on the sun by the planets and the effect it has of causing the sun to process around the center of the solar system due to the changing configuration of the planets. This evidently causes the rotation of our world to vary very slightly, in terms of ms’s for a 24 hr day now this changing rotational speed although very small could have an effect on the principal ocean currents ( bit like the gas sloshing around in your gas tank ). Does anyone out there have any thoughts along these lines?
david says
We are indeed lucky that the sun is coolish ATM otherwise the current awful lack of sea ice would be more awful (http://nsidc.org/arcticseaicenews/) and the near record global temperatures (http://www.ncdc.noaa.gov/oa/climate/research/2008/jul/global.html#temp) would probably be a record. Let us all hope the lack of sun-spots continues, and provides us a buffer from man made global warming.
BTW Jen, how is that list of peer reviewed climate science papers from the local sceptics coming along?
SezaGeoff says
Interesting TSI dataset. We are continually told that the 1 to 1.5% change in TSI could not possibly cause significant Earth variations, but that percentage is the TSI standardised to 1 AU. If you take the variation at the earth by using the earth position column, the variation can hit 6%. Surely that would have a significant affect?
Joel says
David, we’re not here to do your homework for you. If you can’t find sceptical peer-reviewed papers, then you’re not trying and are simply reinforcing your own bias.
This is a list from another website. Have fun.

barry moore says
David, instead of reading other peoples propaganda “the current awful lack of sea ice ” go to woodfortrees.org and just get the raw unbiased data then you can make up your own mind about such statements. Herr Gobals Hitler’s propaganda minister once said ” if you tell a big enough lie ofter enough sooner or later everyone will believe it” I think the IPCC and all its hangers on have taken that statement to a new height. You will find that over the last 30 years the SH sea ice has increased and the NH ice has decreased about 1/2 million sq Km but has been increasing for the past 2 years. Yes it is cyclic yes we have been through a normal warm cycle for which there are a number of reasons. But major change absolutely no way. Also the Antarctic ice by satellite readings is the thickest it has been since the readings were started 30 years ago.
barry moore says
Good list Joel and of course it is only a fraction of what is out there if I may suggest a few more.
I think the best fundamental physics paper is Climate Change by John Nicol.
Heinz Thieme has produced a number of papers from a thermodynamics point of view.
I think one of the foremost expert ice core scientists is Zbigniew Jaworowski, he has totally destroyed the IPCC ice core data. Also J.J.Drake Ice Core Corrections is very interesting.
david says
Joel, nice try.
Perhaps your next list my consist of LOCAL climate sceptics and PEER reviewed science journals.
Perhaps when you are done you might also tell the readers of this blog about the “editorial” policy of E&E and the why a climate paper would appear in a “journal” called “Journal of American Physicians and Surgeons”.
Tilo Reber says
david:
“Joel, nice try.”
First you ask for them, pretending that they don’t exist. Then when you get them you look for idiotic little excuses and qualifications that you can use to dismiss them. That’s why alarmists have no credibility.
Louis Hissink says
David
So tell us what the “editorial policy” is of E & E then.
Incidentally ‘peer review’ actually means not publishing anything that upsets the funding system.
It replaced “refereeing” scientific papers when the post modernists hijacked academia some 30 years ago. Supporters of Socratic Science are all about ensuring a scientfic consensus, and this is what peer review is all about – maintaining scientific consensus.
Except it isn’t science.

David,
Why do sceptics have to be local? That qualifier is moronic and indefensible.
The list wasn’t mine. I don’t agree with the listing of every single paper (nor have I read but a fraction). Nevertheless, there were also papers from:
Climate Research
Geophysical Research Letters
Journal of Climate
Journal of Geophysical Research
You’re playing the consensus card and its garbage.
I was in 3 different countries in July (Canada, US, Australia). All ridiculously cold. The contention that this July was the 5th warmest on record is hard to stomach. UAH shows it to be pretty average.

Ahh

errr No! Are yours paid by the mining industry?
Paul Biggs says
David – Isn’t Robert Baker mentioned in the article ‘local?’ Bob Carter springs to mind who looks at climate on geological timescales, and Prof Aynsley Kellow who was a referee for Chapter 19 in the [IPCC] Report on ‘Key Vulnerabilities and Risk Assessment,’ but doesn’t agree with its conclusions despite being a signatory. That’s 3 without really trying.
GraemeBird. says
Generally speaking the longer a solar cycle takes to come to peak activity the weaker its going to be. This is cycle 24 and the solar people were divided on how strong it would be. But they appear to have been united on the idea that solar cycle 25 will be incredibly weak.
Looking at the historical data you will see that you can get away with one weak solar cycle and you won’t necessarily have much of a change in the air temperature. This is because the air temperature is the tail and the dog is accumulated energy in the oceans.
But you won’t ever have two weak cycles in a row and not get dramatic cooling. 23 was weak by 20th century standards. If 24 is weak the cooling trend just started will continue and it will set us up for a truly catastrophic plunge during the time period of solar cycles 25 and 26.
Leftwingers never pay up on bets. But if you could legally lock it in, you could bet your last dollar on the fact that the 2030’s will be substantially colder than the 90’s. This won’t be a line-ball call and even Goddard won’t be able to finesse the data away.
This will be a serious disaster.
Barry Moore says
Graeme; I am interested in how they project out to cycle 25 and 26. I have found papers by solar physicists which explain the prediction for the coming cycle 24 based on the relative strength of the polar to the toroidal magnetic fields. Statistically I understand how past solar cycles can be related to climate. I agree the end of 23 does not seem to be here yet and the sunspot number for july was at a record low so we have been 3 years in the single or low double digit numbers with no sign of recovery I agree it does not look good.
dhogaza says
E&E is garbage, but there are some credible journals in there.
However, when James Annan is listed as a “skeptic”, you begin to realize that you’d better read each paper on the list before you believe that the research is actually questioning the consensus position.

yes, reading papers carefully is always the right thing to do. I have noticed in several climate papers that there seems to be a de rigeur statement about AGW even when the paper would seem to undercut the AGW science.

So, are you making a prediction of an ice age?
Gary Gulrud says
“Leftwingers never pay up on bets.”
They’re called welchers here; no credit is extended to them.
GraemeBird. says
“So, are you making a prediction of an ice age?”
A “LITTLE” ICE AGE YES.
Thats what the science says. There is simply no getting around that. But so far I do believe that we ought to be able to avoid the full-blown version if at first we can defeat socialism in science.
Each new little ice age has a more than 50% chance of being more severe than the last. Thats just a fact.
But I surmise that the glacial period only gets locked in when the ice interferes witht the ocean currents. So we can avoid this side of it hopefully but only so long as we are a free and viable civilisation. You leave it up to nature and nature will cock it up every time.
But yes we are on the cusp of a so-called “little ice age”.
No question about that at all.
Things change if you only go on the scientific evidence. It changes everything. The prattling of puny humans becomes meaningless. The leftists have their mantras and its the commie version of wishing upon a star.
THE LEFTISTS THINK IN THEIR HEARTS THAT IF A MILLION OF THEM CAN LIE A MILLION TIMES IT WILL ALTER REALITY.
But it won’t.
So yes if we are only going on scientific evidence then we have a “little-ice-age” on our hands.
The decade I can be absolutely sure of is the 2030’s. But I speculate that the cooling will move apace pretty much from here on in.
GraemeBird. says
“Graeme; I am interested in how they project out to cycle 25 and 26. I have found papers by solar physicists which explain the prediction for the coming cycle 24 based on the relative strength of the polar to the toroidal magnetic fields.

They cannot predict cycle 26 as far as I know. I said “during cycle 26” for entirely other reasons. Air temperature correlates with the prior cycle even better than with the current one for very good reasons.
Don’t ask me for the Sami Solanki link that proves this because all the good stuff seems to go AWOL on the net.
As to cycle 25 it appears that a consensus has developed due to a surface conveyer on the sun. This surface conveyer has a big leadtime and so it wasn’t 25 that had the doubt factor about it. But the predictions of 24 can sound like omens. They can sound like omens much to the delight of science-frauds and failed analysts like Quiggin., who calls all people who look for patterns “cycle-cranks”
Thats where the disparity is here. With 24 they had to go on prior patterns and rules of thumb. The whole thing is done on rules of thumb at the moment but this is a valid thing.
But the reason that they are so sure of the disaster of cycle 25 is that they bore witness to the surface conveyer. Whereas their speculations of cycle 24 were far more indirect.
I say that the 2030’s will be disastrously cold because thats the only decade I’d wager my entire superannuation on.
But being less of a pussy about it, and waging a good bet, I would suggest to you that the cooling will start pretty much right away. With only one or two up years all the way down to the 2030’s.
Its a weakass thing to say that the cooling WILL!!!! start pretty much right away. Because as we all know its already started.
You might get some mild uptick after Forbush events, after the next solar maximum, or during the period after the gulf stream has been in a strong phase. But I would see a sort of situation of 8 years of cooling against 3 years of feeble warming and a sort of continual oscillation down clear through the 2030’s.
sunsettommy says
It is plain silly to be predicting an ice age on a slow solar cycle.
The DAULTON MINIMUM is the only possibility at this time.Beyond that is sheer speculation.
GraemeBird. says
No no you have it wrong. Progressively worsening “little-ice-ages” have to be considered the default position.
As tragic as they are and will be for puny humans they are the norm. They require no predictive capacity. The idea that we might avoid them is where the speculative thought comes in.
The last glacial period apparently began in this slow fashion around 112000 years ago. That at least is what I’ve been able to glean. But it didn’t really get locked in until much later. Perhaps from memory about 83000 years ago. The geneticists tell us that by 70 000 years ago most of the human race had been slaughtered.
I say this at the risk of getting our environmentalists excessively excited at the prospect of a renewed slaughter.
We were in full-blown glacial conditions at 70 000 years ago. And it oscillated up and down from there. Research needs to look at physical obstructions to the gulf stream to see how this nastiness gets locked in.
My understanding is that things were not too much different at 70,000 years ago, as compared to the ice maximum of 18000 years ago.
We can stop this disaster if we try.
SJT says
“We can stop this disaster if we try.”
How? What do we have to do?

I just told you. A number of things can be done to stop the glacial period being locked in. Nothing can be done to prevent this next little-ice-age. But there are some things that might be done to prevent such occurences from locking us into an endless deep freeze. The most important is heading off any obstruction to the gulf-stream.
For example Heinrich events lead to a lot of ice being dumped on the Gulf stream periodically. And each time this is done that sends us backwards and stops us getting out of the glacial period. Particularly harmful is the ice that leads to Heinrich events off Hudson bay.
We could find a way to reduce aerosols. Not only human aerosols but those from volcanoes. We could find a way to reduce friction here and there in the ocean currents and particularly the gulf stream.
Ice moves like a slow-motion river. We could strategically nuke some parts of the land ice sheet to stop it moving forward. We might cover large areas of farmland with Ethylene tetrafluoroethylene. Sometimes it may be possible for someone to buy up ice-covered land cheaply, cover it with Ethylene tetrafluoroethylene, and reclaim this land for agriculture. Certainly the ice-damaged land would be cheaper so thats an economic opportunity.
We don’t want to be getting rid of sea ice. Because sea ice is a great insulator. Heinrich events happen, for example, due to heat buildup because of ices insulative capacity. But there is an exception where the ocean currents are concerned. We want to pre-empt ice getting near to anywhere that they may obstruct the oceans currents.

Of course heating is dead easy to reverse. We would simply take the SO2 that we had scrubbed out when making liquified coal. Then what we’d do is when a commercial airliner was flying near the equator in open water it would shoot an SO2 missile into the upper stratosphere. Cheap and easy. No problem at all. But the situation of problematic warming isn’t going to occur in the first place.

“he Bureau of Meteorology has rejected Baker’s reasoning and a paper by him was not accepted by the Australian Meterological Magazine.”
So much for peer review. That ought to be the end of this particular cult. This shows that stupidity in the public sector is our gravest problem.
