Britain Closes Airspace as Volcanic Ash Spreads

The eruption, 10 times more powerful than another one nearby last month, showed no sign of abating after more than 24 hours of activity, a University of Iceland volcanologist, Armannn Hoskuldsson, told Reuters.

And over at the FT
Big volcanic eruptions send more than enough dust and gas into the atmosphere to have a meteorological impact. The most recent was the 1991 eruption of Mount Pinatubo in the Philippines, which cooled the world by about 0.5°C over the following two years.
This Icelandic eruption is not powerful enough to have such an effect, though it might do so in the future if the eruptions gain strength.

Sell summer buy winter?
