READING (10 marks)
1 Read the article and number the main ideas (a–f) in the order that they are mentioned. 1 mark for each
correct answer.
a the glaciers are melting faster than ever before
b the speed at which glaciers travel
c what happens when there is not enough snow
d the glacial melt is causing the earth’s oceans to grow
e efforts to understand what is happening to the glaciers
f the development and life of a glacier
Until recently, the world’s frozen glaciers remained unchanged for millions of years. These ice sheets start life as
snow, turn to glaciers and eventually crash into the sea. They are essential to the world’s biodiversity. However,
across the globe these huge masses of snow and ice are melting. The impact on our environment is already evident.
A single glacier can move up to a metre every hour. For example, an astonishing 20,000 trillion tonnes of ice move
across the state of Alaska every day. And this has been the case for over three million years. However, Alaska’s
100,000 glaciers are now under threat of disappearing because they are very sensitive to the effects of climate
change. To better understand how and why this is having such an impact on Alaska’s glaciers, in recent years parties
of scientists have followed the melt streams that run through these slowly disappearing mountains of ice and snow.
These fast rivers of freezing water are formed as glaciers melt, and are an important measure of glacial health.
Every glacier is in balance. The amount of snow falling in winter must equal the amount that melts in the summer. If
that balance changes, and there is less snow than the amount that melts in the summer, the glacier will disappear.
Right now, that is what is happening. These glaciers are melting faster than they are growing. And when a glacier
disappears, it is gone for good. It tumbles off the mountains and into the sea, never to return.
Alaska’s glaciers are retreating at an increasing rate. Every year 19 trillion tonnes of melt water are pouring
into the sea and not being replenished. As the glaciers melt, it is the rest of the world that is affected. Alaskan
glaciers are melting so fast they currently account for ten per cent of the world’s rising sea levels. This is the most
dramatic transformation the area has undergone since the last ice age and shows how global warming is changing
our environment. Already, many of the world’s island nations are under risk of flooding. Very soon, these small,
defenceless countries could be completely submerged.
