Evidence Card G: Pinatubo Eruption 1991
Estimated amount of
carbon dioxide released
from rebuilding:
~ 1 million tons
An estimated 81,000
buildings were destroyed
or damaged by the
Pinatubo eruption. In
order to repair buildings
and roads, people
burned more fuel than
normal.

Evidence Card H: Pinatubo Eruption 1991
Estimated amount of carbon
dioxide the destroyed forest
would have taken in:
~ 3 million tons
About 155 square
kilometers of forest
were destroyed. Carbon
dioxide in the atmosphere
increases when trees are
destroyed because trees
take carbon dioxide out of
the atmosphere. The forest
may eventually regrow.

Evidence Card I: Eyja Eruption 2010
Estimated amount
of carbon dioxide not
released because of flight
cancellations:
~ 3 million tons
Approximately 107,000
airline flights were
cancelled because of ash
in the air from the Eyja
eruption. When flights are
cancelled, those airplane
engines are not burning
fuel, so less carbon dioxide
is released.

Evidence Card J: Eyja Eruption 2010
Estimated amount of
extra carbon dioxide
taken in by algae:
~ 15,000 tons
Ash from volcanic
eruptions has nutrients
that help algae (which are
like tiny plants) grow in
the ocean. Algae take in
carbon dioxide from the
atmosphere in order to
live and grow.
