Question

What is the overall trend shown in this graph?

Answer 1

The graph shows an increasing trend in glacier ice loss with advancing years. This could be hypothesized to be as a result of increased global temperatures that are melting the ice.  Melting of the ice also causes an increase in the ocean levels. This phenomenon is referred to as global warming.  

Answer 2

Answer: Melting of the glaciers with time

Explanation: From the given graph, we can determine that the red line indicates the rise in the melting of glacier (rise in the sea level height). This melting of ice are due to the reasons such as pollution, increase in the amount of green house gases, rate of increasing incoming solar radiation, decrease in the albedo, thereby increasing the height of sea level. This is called the global warming.

According to the graph, the sea level will rise to a height of 18 meter by 2015.
