Scientists claim that air pollution causes
a decline in the world’s average air
temperature. In order to prove that theory,
ecologists have turned to historic data 【M1】______
in relation to especially huge volcanic
eruptions. They suspect that volcanoes
effect weather changes that are similar with 【M2】______
air pollution.
One source of information is the affect of 【M3】______
the eruption of Tambora, a volcano in
Sumbawa, the Dutch East Indies, in April
1815. The largest recorded volcanic eruption,
Tambora threw 150 million tons of fine ash
into the stratosphere. The ash from a volcano
spreads worldwide in a few days and remain 【M4】______
in the air for years. Its effect is to turn
incoming solar radiation into space and
however cool the earth. For example, 【M5】______
records of weather in England show between
April and November 1815, the average
temperature has fallen 4.5 F. During the 【M6】______
next 24 months, England suffered one of
the cold periods of its history. Farmer’s 【M7】______
records from April 1815 to December 1818
indicate frost throughout the spring and
summer and sharp decreases in crop and
livestock markets. Since there was a time
lag of several years between reason and 【M8】______
effect, by the time the world agricultural
commodity community has deteriorated,
no one realized the cause.
Ecologists today warn that we fane with 【M9】______
a twofold men-ace. The even-present
possibility of volcanic corruptions, such
as that of Mt. St. Helens in Washington,
added to man’s pollution of the atmosphere
with oil, gas, coal, and other polluting
substances, may bring us increasing 【M10】______
colder weather. [br] 【M6】
