But the climate has heated up at an accelerated rate and now it might

It may indeed, but that doesn't mean it will inevitably become a problem
here.

Good point.

It is actually undoing millions of years of evolution by letting species mix
willy nilly.
Over long time spans, you get more and more species and species mixtures
evolving that are highly specific to particular locations and habitats and
which can do this because they are isolated
Then when we come along and mix them with each other you get species warfare
and you end up with fewer species as one species replaces others either
directly through competition or indirectly through habitat loss/change (e.g.
Rhodendron ponticum in SW Ireland are replacing Oakwoods and all the mosses
and liverworts that live in them). That is backwards evolution towards the
kind of species mix you get in supermarket carparks.
