A question on climate

The recent series of CDT articles about “climate change” (formerly called “global warming”) reminded me of an article in the June 2015 issue of National Geographic Magazine.

In that article about Canada’s Yoho National Park, McKenzie Funk mentions receding glaciers first noted by members of the socially prominent Vaux family in 1894, after their first visit to the park in 1887. The extent of the changes over a period of only seven years is not described in the article, but evidently they were significant enough to prompt the family to continue their extraordinary photographic documentation of the phenomenon for “the greater part of two decades.”

Unlike most NGM articles in which melting glaciers or sea ice, changes in air or surface water temperatures, or changes in distribution or abundance of plants or animals are noted, Funk’s article does not posit human use of fossil fuels (primarily coal to produce electrical power and gasoline in hundreds of millions of motor vehicles) as a causative factor for the receding glaciers in Yoho.

I’d like to believe that’s because he realizes such use was not operative on a global scale in the past decade of the 19th century when the Vaux family first made their observations.

That begs the question: If not from anthropogenic “global warming,” why were Yoho glaciers receding in 1894? Funk offered no plausible explanation in his text and NGM editors offered none as footnotes. Can local proponents of “climate change” theory enlighten us?
