Well, it does make sense yes, which is why that view has become accepted. There are some facts that seem to give pause for thought though, like it apparently being much warmer than today in medieval times. This can be hard to see because temperature records don't go back that far, but we know that the Romans appeared to once grow wine near Scotland, something totally impossible today (in fact it only became possible to grow wine in the south of England very recently, a "new" thing blamed on global warming). It's unclear how the Romans could have done that unless grapes were very different or the weather was very different.
