Two major volcanoes — El Chichon in 1982 and Pinatubo in 1991 — caused global average temperature to dip as a result of volcanic ash, soot and debris reflecting sunlight back into space

Let's not forget Indonesia's Mount Agung, which is spewing tons of ash into the skies as we speak!

Note also that any report of melting ice at the South Pole should probably include mention that there are at least 91 volcanoes under the southern ice. But any melting taking place is my fault.
