It sends a great deal of energy to the Earth as well. Up to 10 billion tonnes of matter at up to 9,000 K is a considerable amount of heat.

"Ash Cloud Rises Above Restive Chilean Volcano" "Chile's Hudson Volcano released three huge columns of steam and ash that combined in a cloud more than 3 miles high on Friday, threatening a much larger eruption that had authorities in Chile and Argentina on red alert. Chilean officials evacuated 119 people from the immediate area, and other nearby residents prepared to flee as melting snow and ice caused the Aysen river to overflow its banks. The steam and ash was coming from three craters, ranging from 650 feet to 1,600 feet wide, and with earthquakes shaking the mountain, a major eruption could occur within hours or days, Chile's national geology service said. Already, a plume of ash and steam spread 7.5 miles to the southeast, toward Argentina." www.foxnews.com/world/2011/10/28/ash-cloud-rises-above-restive-chilean-volcano/

"New paper speculates on volcanoes during the Little Ice Age" "Scientific estimates regarding the onset of the Little Ice Age range from the 13th century to the 16th century, but there is little consensus, Miller says. Although the cooling temperatures may have affected places as far away as South America and China, they were particularly evident in northern Europe. Advancing glaciers in mountain valleys destroyed towns, and paintings from the period depict people ice-skating on the Thames River in London and canals in the Netherlands, places that were ice-free before and after the Little Ice Age. “The dominant way scientists have defined the Little Ice Age is by the expansion of big valley glaciers in the Alps and in Norway,” says Miller, a fellow at CU’s Institute of Arctic and Alpine Research. “But the time in which European glaciers advanced far enough to demolish villages would have been long after the onset of the cold period.”" wattsupwiththat.com/2012/01/30/new-paper-speculates-on-volcanoes-during-the-little-ice-age/

Alaska heard from. "Alaska Update: Possible Small Eruption from Kanaga and Continued Activity at Cleveland" "Add another Alaskan volcano to the list of recently restless systems. Kanaga, near Adak (50 km to the east), has been reportedly erupting over the weekend, with both a weak ash plume spotted via satellite and volcanic tremor showing up on the local seismic stations (however, the local station for Kanaga is down). All of this prompted AVO to raise the alert status to Yellow/Advisory over fears of larger explosive eruptions. It has been almost 17 years since the last confirmed eruption from Kanaga, a VEI 2 event that produced mostly explosive material. However, eruptions in 1994 did also produce lava flows – a pretty typical combination in these Aleutian stratovolcanoes." www.wired.com/wiredscience/2012/02/alaska-update-possible-small-eruption-from-kanaga-and-continued-activity-at-cleveland/

But wait this is impossible as CO2 is the dominate forcing factor and volcanoes emit CO2. Who would have ever guessed that volcanoes could cause a change in climate oops weather. "Aerosols from Moderate Volcanos Now Blamed for Global Warming Hiatus" "While looking for quotes on an upcoming post about Ocean Heat Content, I ran across the press release for a new paper (in press) by Neely et al, which blames the recent slowdown in global warming on smaller more moderate volcanos." wattsupwiththat.com/2013/03/02/aerosols-from-moderate-volcanos-now-blamed-for-global-warming-hiatus/

Has it been compared with 70´s cooler years? (for closer previous cooling within satellite era? Again, it seems reasonable that it could be a new variable to be taken into account (natural emissions trend) but to put all the "blame" on either CO2 or SO2 sounds like a rather non scientific simplification
