Do you mean Clydesdale horses?
They’d certainly be bigger than the average horse.
Which is absolute crap. The Chineese have been recording sunspots for a thousand years. Persian and Indian astronomers also have records going back hundreds of years. And there was a long dry spell called the Maunder minimum. It lasted from 1645 to 1715.
So called 'climate scientists' are outright liars.

I was wondering if these guys were trying to take the position that the documented drop in solar activity during the Maunder Minimum had no effect on earth’s climate...
They also have a far large throughput, including gaseous emissions.

If the earth has not been this warm for 2,000 and the mini ice age came in between it does not take a rocket science to figure out global tempertures rise and fall naturally. I tend now not to believe anything from the climate science computer geeks that receive grant money to make climate computer projections. It’s to tempting to do the grantors bidding to keep one’s job. In 2012 after obama’s defeat we should make sure we go after the grant fraud, EPA fraud that the socialist democrats commited in funding these phoney studies.
It’s important (to progressives/liberals) to peg the cause of the little ice age on volcanic emissions rather than solar radiation because AGW cannot be supported otherwise.
At first the alarmists tried to ignore both the little ice age and the medieval warm period that came before it. That didn't work too well for them. Now they are coming up with other explanations that downplay the sun's role and emphasize air pollution’s role. To them a volcano IS mother nature's equivalent to SUV’s.
If you will notice this “theory” is once again based largely on computer models that they manipulated to get the results they wanted. The article starts off with, “the Little Ice Age began abruptly between A.D. 1275 and 1300, triggered by repeated, explosive volcanism and sustained by a self-perpetuating sea ice-ocean feedback system”. Then they get a little more specific, “the Little Ice Age was caused by an unusual, 50-year-long episode of four massive tropical volcanic eruptions.” Never mind that the previous statement said that the Little Ice Age began abruptly between A.D. 1275 and 1300 which is a 25 year period.
Then we learn that, “This is the first time anyone has clearly identified the specific onset of the cold times marking the start of the Little Ice Age,. Umm, yeah right... I guess if you ignore textbooks written fifty years ago that might be true. Since they claim to be the first, I would like to know exactly which “four massive tropical volcanic eruptions” triggered The Little Ice Age.
Of course it gets back to, “Our simulations showed that the volcanic eruptions may have had a profound cooling effect. I think that most people are aware that volcanic dust in the atmosphere does appear to have a cooling effect on the climate, however it is generally thought that this effect is short-lived because the excess dust generally settles out within a year or two at most. If you ignore the effects of gravity and precipitation in your computer models I suppose that this phenomena could be drawn out far longer than that.
“The team used the NCAR-based Community Climate System Model to test the effects of volcanic cooling on Arctic sea ice extent and mass.” I would be curious if the physical evidence for the massiveness and timing of the four tropical volcanoes is in the historical record or if the evidence is derived from the study’s own computer models. Given the past actions of these particular researchers I would guess that physical observations and evidence played a far smaller role than did the reliance on the all-knowing computer model.
“Then they get a little more specific, the Little Ice Age was caused by an unusual, 50-year-long episode of four massive tropical volcanic eruptions.
I wonder where the massive eruptions were. All in Iceland?
All in tropical Iceland...
1150 A.D. - Quilotoa, Ecuador Erupts; Volcanic Explosivity Index (VEI) = 6
1150 A.D. Little Ice Age (First Peak) Begins
1259 A.D. - Very large eruption, Origin Unknown. Twice the size of the Mt.Tambora eruption in 1815 A.D. - this would make a Volcanic Explosivity Index (VEI) = 8 or more; possibly qualifying as a Super Volcanic Eruption.
Antarctica ice core data; Norwegian tree rings; England and Europe - numerous references to dark skies and unseasonable cold, one obscure reference to pillar of fire in western sky; Chinese reference to pillar of fire in southern sky; Indonesian description - near Krakatau - magma rose in a miles wide column into the troposphere lasting for some days before subsiding, according to refferences.
1452 A.D. - Kuwae, Vanuatu, New Hebrides Arc Erupts; Volcanic Explosivity Index (VEI) = 6.
1460 A.D. - Little Ice Age (First Peak) Ends
See my post 15
I witnessed the Mt. St Helen's eruption; it looked pretty massive to me. Which four “massive” tropical volcanoes which took place in a 50 year period that supposedly triggered the little ice age are they referring to in the study? Are they referring to actual events or events that they believe happened because of their simulation results? The article does not make it clear and it certainly makes no reference to the three events you mention that were spread over a 300 year period not a "50 year" period.

Yours is based on historical events not computer modeled events.

Don’t’cha just hate it when historical events contradict the reality of computer models?
