SHRINKING SHEEP!
So, who would have figured that climate change is shrinking sheep in Scotland?
Scientists first began studying Soay sheep, on the island of
Hirta in the St Kilda archipelago, in 1985. Since then, the sheep have
decreased in size by 5% – their legs getting steadily shorter and their body weight decreasing. This strange phenomenon was first reported in 2007, but the reason for it remained under debate.
Now the Professor leading this project has determined that climate change has to be the key factor influencing this change in stature. Given the rise in Scottish Nationalism over this same period, could it also be shrinking the brain power of humans? Och Aye!
Maybe before he started claiming that the sky was falling and blaming it all on man made climate change, but should have a read of this.

A small number of a species on an island can either become larger or smaller over time.
