Cold Weather Due to Iceland's Volcano?

Everyone forgot that Iceland injecteda great mass of particulate into the Northern Hemisphere well above the polarenclosing jet stream causing a lot to stay inside the Arctic air mass.  Unsurprisingly we have a decisively changedweather system.

This particular effect should begone as we now head into spring.

Worse news is that another majorvolcano in the center of the island is suddenly showing a lot of activity.  Its capacity to produce ash is much largerand it is able to cause crop threatening cooling.

I will not bother with the nameas no one can pronounce or spell it anyway. If it erupts then that will be soon enough.

Cold weather due to Iceland'svolcano?

We're hearing all kinds of reasons for the cold snap and severe weatherglobally, with the result that the global-warmingthesis is being raked over the coals, so to speak.  But is anyonediscussing the Icelandic volcanic eruption of last year as the cause? It seemsas if most of the world has forgotten the eruptions of Eyjafjallajökull,"which, although relatively small for volcanic eruptions, caused enormousdisruption to air travel across western and northern Europe over an initialperiod of six days in April 2010."

If history is an example, it is quite possible that this season'sarctic freeze in the Northern Hemisphere, as well as other weather patternssuch as the cyclone in Australia, are results mainly of this recent volcanicevent on Iceland. Indeed, this phenomenon is common enough to have a name,"volcanic winter."

Historic cases of volcanic winter

The following examples of volcanically induced weather disruptions comefrom the Wikipedia article "Volcanic Winter." Oddly enough, Wikimakes no mention of this past year's event and its possible role in thisseason's cold snap.

The extreme weather events of 535–536 are most likely linked to avolcanic eruption.

The Great Famine of 1315–1317 in Europe may have been precipitated by avolcanic event, perhaps that of Kaharoa, New Zealand,which lasted about five years.

In 1452 or 1453, a cataclysmic eruption of the submarine volcano Kuwaecaused worldwide disruptions.

In 1600, the Huaynaputina in Peru erupted. Tree ring studiesshow that 1601 was cold. Russiahad its worst famine in 1601 to 1603. From 1600 to 1602, Switzerland, Latviaand Estoniahad exceptionally cold winters. The wine harvest was late in 1601 in France, and in Peruand Germanywine production collapsed. Peach trees bloomed late in China, and LakeSuwa in Japan froze early.

A paper written by Benjamin Franklin in 1783 blamed the unusually coolsummer of 1783 on volcanic dust coming from Iceland, where the eruption of Lakivolcano had released enormous amounts of sulfur dioxide, resulting in the deathof much of the island's livestock and a catastrophic famine which killed aquarter of the population. Temperatures in the northern hemisphere dropped byabout 1 °C in the year following the Laki eruption.

The 1815 eruption of Mount Tambora, a stratovolcano in Indonesia,occasioned mid-summer frosts in New York State and June snowfalls in NewEngland and Newfoundland and Labrador in what came to be known as the "YearWithout a Summer" of 1816.

In 1883, the explosion of Krakatoa (Krakatau)also created volcanic winter-like conditions. The next four years after theexplosion were unusually cold, and the winter of 1887 to 1888 included powerfulblizzards. Record snowfalls were recorded worldwide.

Most recently, the 1991 explosion of Mount Pinatubo, anotherstratovolcano in the Philippines,cooled global temperatures for about 2–3 years.

As we can see, there is sound scientific reason to question whether ornot what we are currently experiencing in many parts of the world is a volcanicwinter resulting from the eruptions in April 2010 of Eyjafjallajökull in Iceland.
