Just to add to the debate, there were no sun spots recorded last month - an indicator of continued cooling? I cannot find this important fact on the BBC however.
SOLARCYCLE 24.com
a month every now and then in a 4.5 billion year time span is not really that important is it? as a sunspot is cooler than the rest of the sun, surely the absence of any would be an indicator of the sun being warmer and therefore I somehow doubt that would affect cooling.

You miss the point - to expand:
Drop in solar activity has potential effect for climate on earth.
The sun has reached a milestone not seen for nearly 100 years: an entire month has passed without a single visible sunspot being noted.
The event is significant as many climatologists now believe solar magnetic activity – which determines the number of sunspots — is an influencing factor for climate on earth.
According to data from Mount Wilson Observatory, UCLA, more than an entire month has passed without a spot. The last time such an event occurred was June of 1913. Sunspot data has been collected since 1749.
When the sun is active, it’s not uncommon to see sunspot numbers of 100 or more in a single month. Every 11 years, activity slows, and numbers briefly drop to near-zero. Normally sunspots return very quickly, as a new cycle begins.
But this year — which corresponds to the start of Solar Cycle 24 — has been extraordinarily long and quiet, with the first seven months averaging a sunspot number of only 3. August followed with none at all. The astonishing rapid drop of the past year has defied predictions, and caught nearly all astronomers by surprise.
…
In the past 1000 years, three previous such events — the Dalton, Maunder, and Spörer Minimums, have all led to rapid cooling. One was large enough to be called a “mini ice age”. For a society dependent on agriculture, cold is more damaging than heat. The growing season shortens, yields drop, and the occurrence of crop-destroying frosts increases.
gimlet, on a recent link from Poptech there is this: (from Sounds familiar: ?A friend of mine found one station where the temperature gauge was just outside the air conditioner…? Watts Up With That?)
"Still, Akasofu doesn’t completely deny the existence of climate change, so much as question what causes it. One culprit he suggested is the recent lack of sunspots.
“Something is happening on the sun,” he said. “There are no sunspots when there should be 50-100 right now, so people warn the sun has become warmer.”
A similar phenomenon was observed between 1650 and 1700, which coincides with what researchers call the Little Ice Age, a period of widespread cooling that came shortly after a warming trend may have peaked sometime around 1000 AD.
Perhaps just a coincidence, perhaps taken out of context.....but pretty much the same as your last post.

Wonder what that other effect is then ????
(re the LIA, Brian Fagan has written a cracking book on it by the same name. You can get it off Amazon for less than a tenner, possibly for a fiver but note that he specifically says the current warming trend is mostly due to mankind’s activities)
Hi Clippo - how you been?
Not sure what the other effect would be but let me have a wild guess - man made CO2?
and many other sources and groups suggest that there is a cooling trendJust passing but :-

The ‘official’ figures, coming from internationally respected scientific data-measuring organisations suggest/confirm that the globe is still on a warming trend.
(whereas I’ll warrant a guess that g hall’s other ‘cooling’ groups go back to a few nutters like Anthony Watts, Stephen McIntyre etc.)
