Revolution that erupted from two volcanoes

Like the eruption of Mount Pinatubo in the Philippines in 1991, these eruptions blew large amounts of
sulphurous ash into the atmosphere, partly blocking the sun`s rays and temporarily cooling the climate.
France in 1789 was already bankrupt because of a long war in America. The government was threatened by a
plot to organise riots financed by an ambitious aristocrat who wanted to become king. 1___The result of the eruptions
was several years of cold, wet weather in Europe. Two violent storms in 3788 and 1789 destroyed the harvest in many
parts of the 20 country and the resulting shortage of corn was made worse by the Finance Minister`s refusal to import
corn from abroad on the grounds that the state could not afford it.
2___ When the people of France saw wagons full of 25 com go through their village streets they said, ‘There
is plenty of com, but not for us: it`s for the king, the aristocrats, the rich who have plenty to eat while we go hungry.’
And then the maddened people would throw the sacks of corn into the nearest river.
Another volcanic eruption – in Indonesia in April 1815 – may have helped cause Napoleon’s defeat at the
battle of Waterloo. 3_____1816 was called the ‘year without a summer’. Torrential rains marked the beginning of the
Waterloo campaign, creating 35 deep mud which for many hours prevented Napoleon from moving his big guns.
The French revolution is one of many examples where a change of climate was the final blow to an already threatened
society.
40 The Little Ice Age, which started about AD 1400, threatened the Scandinavian colony in Greenland.
4_____ They might have survived if, instead of sticking to their aristocratic society, they had moved from farming to
hunting, like the Eskimos who replaced them.
At about the same period the great civilization of the Mayas in Yucatan faced ever worsening droughts.
5____This had the opposite effect to that intended, since forcing people into the army meant they had to leave their
land.
