Hmm: New York Times casually mentions that "one of the most rapid glacial retreats ever recorded" occurred well before the invention of the SUV

Along a Verdant Shore, a Vision of Past, Present and Future - NYTimes.com

George Vancouver sailed the waters of Ice Strait as a British Navy captain in 1794, some 45 years after the glaciers at Glacier Bay had reached their zenith. The bay is a product of what is known as the Little Ice Age, a glacial period that came and went quickly — between the 16th and 19th centuries — as far as geologic time goes. In the few decades between the glacial maximum and Vancouver’s valiant exploratory voyage, glacier retreat scoured out five miles of terrain.

Less than a century later, John Muir documented 30 miles of retreat, inspiring further study of what is now viewed as one of the most rapid glacial retreats ever recorded. The effort continues today.
