 We saw yesterday how 19th explorers discovered that the Ross Ice Shelf receded by 30 miles in the 19thC.

To add to that picture, this study found that elephant seals migrated to the Victoria Land Coast in the Ross Sea about 8000 years ago, as the region became warmer, and stayed there till about 1000 years ago when sea ice returned.

Meanwhile another study shortly afterwards found evidence that the Ross Sea cooled significantly during the Little Ice Age:

This all indicates that modern glacier retreats are just part of a much longer climatic cycle.
