We often read things like "Humans in hot climates i.e. Kenya
are tall and lean whereas in the cold (such as the Eskimos) they
are short and squat/stubby because of <heat expulsion blah...>"

Just out of curiosity has anyone calculated the the changes
(whether they are beneficial or not) that would accrue from
being short or tall in these environments?

The reason I ask is quite simple. Pygmies are quite short.
Northern Chinese are tall, and southeast Asians like
Indochinese and even southern Chinese are short.
