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).
