I fully support the findings of Jan Erik Solheim , Kjell Stordahl and Ole Humlum and their very recent paper called The long sunspot cycle 23 predicts a significant temperature decrease in cycle 24 dated February 2012. The abstract reads:
Relations between the length of a sunspot cycle and the average temperature in the same and the next cycle are calculated for a number of meteorological stations in Norway and in the North Atlantic region. No significant trend is found between the length of a cycle and the average temperature in the same cycle, but a significant negative trend is found between the length of a cycle and the temperature in the next cycle. This provides a tool to predict an average temperature decrease of at least 1.0 ◦C from solar cycle 23 to 24 for the stations and areas analyzed. We find for the Norwegian local stations investigated that 2556% of the temperature increase the last 150 years may be attributed to the Sun. For 3 North Atlantic stations we get 6372% solar contribution. This points to the Atlantic currents as reinforcing a solar signal.
Before finding the above paper on WUWT, I had recently done a similar and slightly different analysis.
I took the Annual sunspot numbers for each year since 1900 and noted the solar maximums and solar minimums. I also noted all the years around the solar maximums that had sunspot numbers over say 60-70. These solar active periods around the solar maximums can last as many as 3-5 years . Then I lagged the data by 9 years. Then I looked at the global temperature anomalies Hadcrut3gl for the all the actual years and noted the associated and lagged sunspot numbers. I then added and noted the El Nino active years using the ONI index.
I discovered that global temperatures were rising during the years around the lagged solar active period around the solar maximum and they were down during the period around the lagged solar minimum. Also there were El Ninos at the beginning or during the lagged active sun or solar active or maximum period. In another words the sun really affects the atmosphere not in the same cycle but during the next cycle or about 9 years later . It would appear that the extra solar radiation around solar maximums, heats the surface waters of the major oceans especially the Pacific and Atlantic. The warm water is then transported by the ocean conveyor belt deeper into the ocean waters and down swelled and conveyed around the globe. It reappears as warm upwelling along the South American west coast [and other upwelling locations] and ultimately contributes to the warming of the EL Nino area Pacific waters and modifies the PDO spatial patterns or warming to put more warmer water along the west coast of North America .
Similar event happens in the Atlantic as indicated by the AMO. The longer solar cycles means fewer solar active periods or maximums and less heating 9 years later. A series of short solar cycles in a row will cause more frequent heating and the PDO and AMO will both turn positive or warm simultaneously causing what we now refer to as global warming. The extended global cooling happens when there are series of longer solar cycles with lower maximums. Co2 seems to have little or negligible effect on these large natural cycles. Natural cycles will always dwarf any minor warming from manmade greenhouse gases.
Thus our long term climate is all in the cycles of sun lagged about 9 [ 9-11]years later in its effect and interacting with the oceans which then in turn affect our atmosphere 9-11 year later.
Since we are now in the equivalent lagged year[2012-9=2003] and will next experience the solar effects of the decline of solar cycle #23 [the solar period of 2000 to 2008 ], we can expect cooler weather for at least 6 years plus another nine years after the next warming effect of the solar active period of cycle #24 [ maximum around 2013 to 2014.] So I see no significant warming for 20 years at least [2030 earliest]. This is what ocean cycles like PDO predict and what the 60 year climate cycle predicts but now we may possibly have one of many hypothesis of how the sun does all this.
The El Nino around 2009-2010 was the effect of the last solar maximum of cycle #23 [around 200-2001].
This brief article was meant to continue the debate about the exact mechanism of how our sun affects our global climate It does not answer all the questions and may pose others.
Al Gore on suicide watch.
Oh no! The end is nigh!. Al Gore is chilling! Someone quick send him back to Warm World.
This won’t slow the global warming nuts one bit. They’ll try to raise taxes and institute “social justice” before the cooling begins, then claim victory.
I would rearrange the list to:
1) We need to raise taxes
2) We need to de-industrialize the West
3) We need to invest in green tecnology
4) We're all going to die
Thus, if we are all going to die anyway why bother with the rest? So I say eat, drink and be happy! I'll have another Long Island iced tea and pass the chips.
I hope so. I REALLY need some justification for that snowmobile. Especially as lame as this winter has been up here.
In all seriousness, this is very reliable science. Solar minimums have preceded temperature reductions across the board. We likely won’t see a mini-ice-age like we did in the middle ages, as much of that was due to heavy volcanic activity in the 12th-14th centuries.
Industrialization cannot produce the sort of atmospheric “black out” that comes from normal geocentric processes. Man produces such a miniscule amount of “pollution,” that Earth’s natural scrubbers can do a fine job alone.
Matter of fact, I’ve seen some global cooling/ice age stuff on History/NatGeo lately that makes me wonder if the Liberals at those stations are going to preempt the coming “cold apocalypse.” It’s funny to watch them squirm. They can’t just chalk it up to nature doing what nature does.
Regarding the Cooling Sun.
But isn’t AGW a religion now? Can’t I live forever if I believe in AGW, veganism, Hope and Change?
Bump for later reading
Believable proofs keep pouring in as to how we may be ready for a mini ice age. Taint going to be a nice thing to have to go through.
Add me to your ping list, please.
You won’t be able to afford the gas for it, anyhow.
Many of you know that I have been writing, about exactly this type of mechanism to account for Earth’s temperature, on FR for the last decade or thereabouts. I have favored a somewhat shorter lag time, but have no quibbles with this proposed 9yr lag. The evidence is so clear that I honestly don’t understand how the IPCC-supporting alarmists are able to honestly maintain that CO2 is largely responsible for the 20th century warming. Crimeny: for the whole second half of the century, Sol was “the warmest it has been for the last 8000 years”, as Solanki and others published around a decade ago. The IPCC ignoring that rather pertinent fact in attempting explanations of temperature is massively delusional, and doing so because they don’t understand mechanisms as to how it could possibly affect temperatures so much is a poor excuse.
I have always believed that the poor immediate correlations were a function of ocean heat transport, which is clearly chaotic. However Svensmark’s cosmic ray mechanism, and Lndzen/Spencer’s tropical clouds mechanism (which may be linked) were welcome additions to the mix of theoretical possibilities for me. No matter what the actual reasons, it is more and more clear that changing CO2 levels account for only a small proportion of the temperature changes of Earth.
Gonna distill me some legislators and greenie activists. Oughta keep me in fuel for a good long while.
In the Religion of Heat, one is one’s own God - more powerful than nature. So let it be written. So let it be done.
