A CRACK IN THE AGW WALL: BRITISH RESEARCHERS ADMIT SUNSPOTS EFFECT CLIMATE
IT'S A START:Sun activity link to cold winter
A period of low solar activity could lead to more cold winters in the UK
The 'Big Freeze' explained
The UK and continental Europe could be gripped by more frequent cold winters in the future as a result of low solar activity, say researchers.They identified a link between fewer sunspots and atmospheric conditions that "block" warm, westerly winds reaching Europe during winter months.
But they added that the phenomenon only affected a limited region and would not alter the overall global warming trend.
The findings appear in the journal Environmental Research Letters.
"By recent standards, we have just had what could be called a very cold winter and I wanted to see if this was just another coincidence or statistically robust," said lead author Mike Lockwood, professor of space environment physics at the University of Reading, UK.
To examine whether there was a link, Professor Lockwood and his co-authors compared past levels of solar activity with the Central England Temperature (CET) record, which is the world's longest continuous instrumental record of such data.
The researchers used the 351-year CET record because it provided data that went back to the beginning of the Maunder Minimum, a prolonged period of very low activity on the Sun that lasted about half a century.
...The Maunder Minimum occurred in the latter half of the 17th Century - a period when Europe experienced a series of harsh winters, which has been dubbed by some as the Little Ice Age. Following this, there was a gradual increase in solar activity that lasted 300 years.
Professor Lockwood explained that studies of activity on the Sun, which provides data stretching back over 9,000 years, showed that it tended to "ramp up quite slowly over about a 300-year period, then drop quite quickly over about a 100-year period".
He said the present decline started in 1985 and was currently about "half way back to a Maunder Minimum condition".
This allowed the team to compare recent years with what happened in the late 1600s.
"We found that you could accommodate both the Maunder Minimum and the last few years into the same framework," he told BBC News.
THEY'RE STILL DENYING THAT THE MINIMUM WAS AND WILL BE AGAIN WORLDWIDE.
BUT IT'S A START.

Pastorius,
So what? Mainstream Climatologists have been saying that sunspots effect climate for years. I saw a problem on the History Channel about a time period refereed to as "The Little Ice Age." It came after a time people refer to as "The Medieval Warm Period." During the little ice age the Earth was significantly colder than now and one of the things that climatologists think caused the cooler temperatures was lower solar activity during that period in world history. People have been talking about how solar activity effects climate for years now. This isn't something that's going to disprove the claim that man's actions are having an effect on the climate.
Here's some more resources on the subject of the little ice age.

You need to put up that blonde ape photo for these guys too.
Damien,
The AGW set did not even acknowledge the Medieval Warm Period. That was part and parcel of the Hockey Stick.
Look it up.
If you can't find it, I'll find it for you.
cjk,
Blonde ape?
That sounds like something Epa would put up. I don't remember it.
Pastorius,
yes they did acknowledge it and they still do. You seem to think that the people who believe that there is convincing evidence that high levels C02 and other greenhouse gases warms the planet, always reject any other cause.
Pastorius,
You seem to think that if you show there is another factor, that means that what you call ANG must be false. You seem to think that its either ANG or something else and not both. That's Fallacious thinking. Also scientists have done studies on the climate during the Jurassic period. Even the ones who are the most certian that man is having an effect on climate now, know full well that humans could not have been effecting the climate during the age of the dinosaurs because their no people. Yet they know that the climate changed through out Earths history even before people, and that there are factors involved in climate other than just greenhouse gases. I don't think there is a single climatologist out there who think that the only thing that effects climate is the amount of greenhouse gases in the atmosphere.
Damien,
You said: You seem to think that if you show there is another factor, that means that what you call ANG must be false.
I say: No, I recognize that weather is complex, and that there are many causes for fluctuations in temperature around the globe. I think the Sun is one of the major causes of Warming. Now, does that sound insane to you, or what? The sun, who woulda thunk?
They tried to minimize the Medieval Warm Period, Damien. They did this because they want you to believe that CO2 is the main cause of temperature fluctuations, which is, in my opinion, an asinine theory.

By the way, the term I tend to use when discussing Global Warming is "Anthropogenic Global Warming."
an·thro·po·gen·ic
/ˌænθrəpəˈdʒɛnɪk/ Show Spelled[an-thruh-puh-jen-ik] Show IPA
–adjective
caused or produced by humans: anthropogenic air pollution.
If the larger of those two volcanoes in Iceland goes off (the one currently erupting and shutting down air travel all over the neighborhood is just the little sister) we may have our own Little Ice Age for a few months and let's see them explain THAT as AGW.
Pastorius,
You said that they tried to minimize the Medieval Warm period? Okay, how?
I don't think that many of them outright denied that the Medieval Warm period ever happened or claimed that the climate was stable before the twentieth century. Pretty much all climatologists think that the sun played a major role in Earth's climate throughout the planet's history, including today. Rea-forming the role the sun has on our climate does not prove that greenhouse gases are not a major factor. Just because CO2 and other greenhouse gases created by human activity wasn't a major factor in the past, doesn't mean it isn't now.
Sorry I have to apologize for something. What I meant when I wrote ANG was Anthropogenic Global Warming. I can't believe I didn't abbreviate it correctly. I'll try to use AGW from now on when trying to abbreviate it.
Damien,
1) Do you understand that Phil Jones attempted to minimize that MWP?
2) Do you understand that the hockey stick graph left it out?
3) Do you understand that it was not a regional event?

Pastorius,
I never said, I thought that the MWP was a regional event. Based on what I know, I would say increased solar activity caused the MWP, and greenhouse gases had little if anything to do with it. However that does not prove that man's activities are to effecting the planet now. Don't forget that people didn't that much coal, and they didn't have gas guzzling automobiles. I don't even think they had any uses gasoline, back than. As for the other things you said, I'll spend some time and look into them. I'll also check out that link you showed me.
Well some of the links you showed me. You just posted more of them while I wrote my last comment.
Damien,
You said: I would say increased solar activity caused the MWP ...
I say: And, of course, the warming we're having now pales in comparison to the MWP.
And, while we know there has been some warming in this past century, we do not ACTUALLY know the source of it.
But, we do know THE TREND HAS REVERSED RECENTLY EVEN THOUGH GREENHOUSE GASES HAVE CONTINUED TO RISE.
So, where's the logic for your side of the argument?
Pastorius,
There maybe other factors that are negating it.
Second of all the Earth's climate is so complex that different areas maybe effected differently.
But, no one knows, do they? And yet, AGW is put forth as being such incontrivertable truth that we are supposed to change the world's economy to accomdate the AGW model.
Damien,
You are arguing with me when you can't prove your side.
"different areas may be effected differently."
Alright, I concede that. But, in effect you are saying, you don't have any idea.
And, that is my point.
The AGW scientists do not really know what they are talking about.
