Climate Change Data Visualizations

The following study is a compilation of figures that analyze ice mass levels from Greenland and Antarctica registered over the period 2002–2014 by NASA’s Grace satellites.

Fig.1. Polar Ice Mass Correlation (2002–2014). Values are anomalies (n=140) gather by NASA’s GRACE satellites relative to timeseries mean. The x-axis represents the amount of ice mass registered on Greenland‘s ice land, and the y-axis represents the amount of ice mass registered on Antarctica’s ice land, for equivalent timeframes. Although we are not analyzing the timeseries in this figure, it shows evidence of a positive correlation between the variables (r=0.95).
Fig. 2. Polar Ice Mass Comparison Trend (2002–2014). This graph shows the comparison between Greenland (blue) and Antarctica’s (red) ice mass during the period 2002–2014 as recorded by NASA’s GRACE satellites. The dashed green line intercepts the x-axis (years) on 2009, from where we can appreciate an acceleration in the decreasing ice mass rate.
Fig. 3. Polar Ice Mass Comparison Trend (2002–2014) + Linear Regressions (Values Prior to 2009). This graph shows what the linear regression for Greenland (cyan) and for Antarctica (yellow) were prior to 2010. These lines give us an idea of what would have been predicted at that time, and the difference with the actual values by the end of 2014.
