This doesn't make sense: "With summertime temperatures typically -10°C to -20°C".
Maybe the negative was mistakenly added, and nobody noticed in editing? 10°C to 20°C would be reasonable for a "forested and grassland plateau".
So this would suggest that the Goidelic languages (Irish Gaelic, Scottish Gaelic, Manx) are derived from the Brittonic languages (Welsh, Breton, Cornish). [1]
I wonder how this affects the different proto-Celtic to modern Celtic languages hypothesis. [1]
This would suggest the following language tree: Breton -> (Cornish / Welsh) -> Irish Gaelic -> (Manx / Scottish Gaelic).

it's reinforced in the same sentence after you cut off your quote and is repeated again further into the article:
> Nash said the caves would have been "quite a cosy place to live, especially compared with the -20°C outside".
There was an ice sheet starting just north of this area, it would have melted at 10°C.
Agreed, that jumped out at me also. Those numbers make no sense

This migration predates the arrival of Celtic speakers by many thousands of years.
There were no Brythonic languages 15,000 years ago.
