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.
