... or are the anomalies wrong?
It is interesting. I thought that Tambora supposedly created the year there was no summer. It seems to me you could look for the ash more effectively in medium to shallow depth marine cores that are located closer to where we live (i.e. not the polar regions). I suppose you would then have to make assumptions about how much sulfur was associated with it. I remember Dana 1981 long ago suggesting that the 1970s cool period was caused by our sulfur emissions and I wasn't sure he wasn't joking but it was repeated on numerous times since then by numerous alarmists. I wonder if they have to revise that theory as well.
This has nothing to do with anomalies. Anomalies are just a way of expressing a number, like saying you are driving 5 mph over the speed limit rather than saying you are driving 70.
This study verified the estimates of volcano effects on the climate after the year 1500; it found nothing new over the past 500 years. It is only more than 500 years ago that these researchers are proposing that volcanic effects have been over stated. This is particularly interesting in tandem with the study linked here yesterday that proposed that the growth of the Amazon forest may have absorbed enough CO2 to cause the Little Ice Age. Both of these studies might be correct, they are at least mutually supporting. One proposes that the effects of volcanoes in 1257 and 1458 was less of a factor in causing the LIA whereas the other proposes that declines in CO2 was more of an effect. Together they suggest the changes in CO2 played a greater role in climate change during the 4th through 19th centuries than previous thought.
These new hypotheses need to be vetted by other research before they become generally established. With current climate we can determine that warming is due to the greenhouse effect by seeing that nights are warming more than days, that the Stratosphere has cooled, and by directly measuring outgoing and incoming long wave radiation. We can't go back and directly test the effects of volcanic dimming versus greenhouse reduction as contributing causes of the LIA.
Watch for more research in this area. We may be learning that CO2 played a greater role in the LIA than we previously believed.
The volcanoes were always exaggerated a bit to keep the models 'accurate'. They had to explain the cooling that happened after Pinatubo. That the numbers don't match up has been known on skeptic blogs for awhile.
Great question! In the early 60s, the volcanos did cool off quiet a bit. However we are still here! We are still a great company with super cool core beliefs. Oh. and that picture. Im a real doctor.
Our volcano's are loosing a certain element from inside the volcano's, because the ALIEN Ships hover over them and we of my Global Teams from all walks of life and I believe their extracting a certain type of fuel from each volcano. Those that erupt they have'nt extracted from. My Teams are filming them both over volcano's all over earth and under the oceans for where there bases are located, plus we found another ALIEN specie from our Triangle films, since we know what the invading ALIENS look like.

Kano: "CO2 could not be the cause of the little ice age, because it would take hundreds/thousands of years to diminish the level of CO2 by natural means. "
Well yeah, NOT TO MENTION that CO2 causes warming, not cooling.
It's ash and SO2, not CO2, that cause cooling.
Zippi: "Then what caused the dramatic cooling?"
The maunder minimum has, for some decades now, been thought to be related to the coldest part of the little ice age.
Concerning whether to look at the poles or nearer the equator to find evidence of volcanic eruptions, it makes a difference what you're looking for. If you're looking at heavier rock and dust, then you do want to look down wind from the eruption. If you're looking for gas, then it gets mixed throughout the world atmosphere fairly quickly. Keep in mind, it's in Hawaii where they measure CO2.
I never really did believe that volcanoes had much effect on climate, one year maybe, the same as I believe CO2 has very little effect, CO2 could not be the cause of the little ice age, because it would take hundreds/thousands of years to diminish the level of CO2 by natural means.
Lin Lyons.
Yeah okay then what did cause the little ice age then
What dramatic cooling? People didn't have thermometers 500 years ago.
Deniers should make up their minds. They also claim warming is due to having CO2 coming out of volcanoes is more than all human emmissions.
OMG! I thought that adjusted data were bad - except, I guess, when Deniers think that they have something to do with something that they have nothing to do with.
