1) No, that's just it -- paleoclimatic evidence shows that climate changes of the sort we're discussing can take place in a matter of a few decades, as the climate shifts from one state to another. It would doubtless take a century or so for desert flora and fauna to establish themselves in southern Europe, just as it took around a century after the end of the Younger Dryas period for the Sahara to turn into savanna, but the crippling droughts could show up much sooner.
2) That's a complex question that will depend on local factors, but odds are that it'll end up with the kind of climate that southern Europe has now.
