This graph shows the Antarctica mass variation since $2002$. 

Interpret the presented data and describe the trend over the past $16$ years.

This graph shows the Antarctica mass variation since $2002$. 

Apart from the overall trend in the data, hypothesise why there are small upward and downward variations in the total land ice mass within a calendar year.

This graph shows the Antarctica mass variation since $2002$. 

Estimate the change in mass for the period $2004–2008$.

This graph shows the Antarctica mass variation since $2002$. 

Analyse the data and comment whether the rate of loss of mass is increasing or decreasing, in the decade following $2008$. Support your argument with mathematical evidence.
