Yes the climate has been changing but the immense tree clearance and

The downs and the northern moors were not cleared of trees in modern
times. The moors were cleared during prehistoric times, the downs in
the middle ages

No, they were cleared much earlier than that. It was the change from
arable to pastoral use that happened in the middle ages.

The Kentish downs were cleared of trees by iron makers looking for
fuel.
