Antarctica (Figure 3.1) is at the forefront of the climate change crisis. We know that it is an important player in global circulations of the atmosphere and the ocean, and that the gain/loss of ice on the continent exerts a major control on sea level. We are also aware that Antarctica has been pivotal in modulating past climate change and sea levels. This appreciation has only been achieved through scientific research over the past fifty years – a remarkable evolution in understanding, considering it was a remote and unknown continent in the early 1900s. Indeed, the first expeditions in which targeted scientific discovery was the sole focus date only to the late 1950s. Considering the rapid evolution in our understanding of Antarctica’s ice sheet, and the continent on which it flows, it is worth taking time to review briefly how we arrived at this point.
