Volcanoes and Climate Change
Large volcanic eruptions can produce winter warming. An analysis of winter temperatures after 12 large volcanic eruptions between 1883 and 1992 showed warming over Eurasia and North America, and cooling over the Middle East.
The effects occurred the first winter after tropical eruptions, the first or second winters for eruptions in the mid latitudes, and the second winter after high latitude eruptions.
