Graph of New Zealands gross greenhouse gas emissions 1861 to 2012

Robbie Andrew has compiled a data set of gross greenhouse gas emissions for New Zealand starting in 1861. So obviously that prompted me to make a line chart.

This image is set at actual size of 535 pixels.

This is an extra large sized image that is displayed too large for the width of the column.

This is a large sized image.

This is a medium sized image.

One point to note is that the line looks very smooth from the 1860s to the 1920s. That's because the data interval is one record per decade up until 1931. The data becomes an annual time series from 1933.

The other point is that the emissions data shows the same pattern of exponential growth highlighted in the global carbon dioxide graph featured by Duncan Clark and Mike Berners-Lee in The Burning Question.
