If the ash clouds persist I wonder what effect it will have on temps and growing seasons up North?

Buy Southern farmland! Wheat futures would be an interesting bet as well.

Read about the Year Without a Summer which was caused by the eruption of Mt. Tambora in Indonesia in April 1815, a year earlier. It was the largest eruption in recorded history and launched 38 cubic miles of ash into the atmosphere. That's a cube of ash 3.4 miles on each side! Massive crop failures resulted.

The amount of ash being thrown up in Iceland is very small compared to Tambora, Pinatubo and St. Helens. But it is in the Northern Hemisphere. Maybe we'll see the effect next year.
