Discussion Overview

The discussion revolves around estimating the number of glaciers in the world, exploring the complexities involved in defining and counting glaciers. Participants share their insights and uncertainties regarding the classification and distribution of glaciers across different regions.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant expresses uncertainty about the number of glaciers, suggesting it might be in the tens of thousands, particularly noting that Alaska has tens of thousands of glaciers.
  • Another participant argues that glaciers are not discrete entities and that some parts of a single ice mass may have multiple names, implying that a definitive count may not be possible.
  • A participant mentions that approximately 10% of the Earth's land surface is glaciated, referencing a source for this information.
  • There is a historical reference to the last glacial maximum around 20,000 years ago, suggesting that understanding glaciers may involve historical context.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the number of glaciers, with multiple competing views on how to define and count them, indicating that the discussion remains unresolved.

Contextual Notes

The discussion highlights limitations in defining glaciers and the challenges in obtaining a reliable count, as well as the potential for varying definitions across different regions.

As strange as it may seem, I have not been able to come up with a reliable figure.

I thought that it might be in the tens of thousands, but was suprised to find (in the process of researching this question) that Alaska alone has tens of thousands of Glaciers.

Other than that, all I know is at least 48 countries are said to contain glaciers as part of their territory.

So can someone help me answer this question.

How many Glaciers are there in the world...?

Thanks in Advance.

Glaciers are not necessarily discreet separable entities, like rivers, nor are they all "named". Some parts of a single icemass have multiple names as well. In other words, I do not think thgere is a definitive answer to your question.

And apparently, that includes virtually all of Canada, including the Great Lakes...

Well, it seems that this was thought to be so during the last glacial maximum around 20,000 years ago.
