Effects of Climate Change
The size of tidewater glaciers is such that the tidewater glacier cycle is several hundred years in length. A tidewater glacier is not sensitive to climate during the advancing and drastically retreating phases of its cycle. In the same region, disparate terminus responses are observed amongst tidewater calving glaciers, but not land terminating glaciers. This is exemplified by the 17 major glaciers of the Juneau Icefield, 5 have retreated more than 500 m since 1948, 11 more than 1000 m, and one glacier the Taku has advanced. This difference highlights the unique impacts on terminus behavior of the tidewater glacier cycle, which has caused the Taku Glacier to be insensitive to climate change in the last 60 years. Concurrently, in both Patagonia and Alaska, there are tidewater glaciers that have advanced for a considerable period, tidewater glaciers undergoing rapid retreat and stable tidewater glaciers.

Famous quotes containing the words effects of, effects, climate and/or change:
“Whereas Freud was for the most part concerned with the morbid effects of unconscious repression, Jung was more interested in the manifestations of unconscious expression, first in the dream and eventually in all the more orderly products of religion and art and morals.”
—Lewis Mumford (1895–1990)
“Oh that my Pow’r to Saving were confin’d:
Why am I forc’d, like Heav’n, against my mind,
To make Examples of another Kind?
Must I at length the Sword of Justice draw?
Oh curst Effects of necessary Law!
How ill my Fear they by my Mercy scan,
Beware the Fury of a Patient Man.”
—John Dryden (1631–1700)
“Then climate is a great impediment to idle persons; we often resolve to give up the care of the weather, but still we regard the clouds and the rain.”
—Ralph Waldo Emerson (1803–1882)
“The incessant repetition of the same hand-work dwarfs the man, robs him of his strength, wit, and versatility, to make a pin- polisher, and buckle-maker, or any other specialty; and presently, in a change of industry, whole towns are sacrificed like ant-hills, when cotton takes the place of linen, or railways of turnpikes, or when commons are inclosed by landlords.”
—Ralph Waldo Emerson (1803–1882)
