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 historical data in relation to especially huge volcanic eruptions. They suspect that volcanoes effect weather changes that are similar to air pollution.
One source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indies the former name of the Republic of Indonesia in April 1815. The largest recorded volcanic eruption, Tombora threw 150 million tons of fine ash into the sky. The ash from a volcano spreads worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation into space and thus cool the earth. For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5F. During the next twenty-four months, England suffered one of the coldest periods of its history. Farmers’ 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 cause and effect, by the time the world agricultural commodity community had deteriorated, no one realized the cause.
Ecologists today warn that we face a twofold menace. The ever-present possibility of volcanic eruption, 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 increasingly colder weather.
选项
A、England’s proximity’ to the sea.
B、Volcanic ash in the atmosphere.
C、Flooding in the area.
D、Pollution caused by the International Revolution.
答案
B
解析
Which was the Cause of cold weather in England from 1815 to 1818?
各选项都是名词性短语,结合主题可推知本题可能考查某地区气温下降的原因。文中明确指出由于火山爆发,将大量火山灰喷到空中,火山灰在大气中停留了几年,将阳光折射回太空,从而导致地球的气温降低,故选择B)。
