Glaciers in Greenland are Shrinking: We can measure how much by satellites and GPS

Learn about glaciers and ice sheets and how important they are for the Earth’s climate. Work with satellite and GPS data to estimate how much the Greenland Ice Sheet is actually melting.

Why are glaciers and ice sheets interesting?

Do you know that if the whole Greenland Ice Sheet had been melted the sea level would rise about 7 meters? During the last 20 years we have seen rapid acceleration in ice shrinking which constantly results in sea level rising. Exploring the ice sheets and glaciers help us to understand the past and predict the future behavior of ice which is the vital thing in climate monitoring. Monitoring ice loss via different methods allows us to get reliable results that can be used as a warning and preparation for the future.

Importance of ice in the climate

Knowing the data from the past we know that the climate was always changing in cycles. The Earth underwent few ice ages with abrupt global warming following immediately after. But looking at the present day data can give you an idea how fast the changes are taking place now. Is it something dangerous that we should be afraid of? Why ice and snow is so important for the Earth’s climate system?

During the exercise you will work with real satellite and GPS data in order to perform few interesting tasks that will help you to understand and evaluate how do the changes look like nowadays and what will the future bring us. Allow yourself to understand the ‘hot topic’ of global warming and feel confident while discussing it with others.

How do we monitor changes of the glacier?

Different methods are used to monitor changes that take place on the ice sheets. But what raw data can mean without people who can understand and make them useful for the others? During the exercise several approaches will be presented to show how raw numbers from satellites and GPS can be transformed to knowledge on the condition of the Earth’s ice-covered regions.
