I have read that Bartletts in hot areas of California are self-fertile.
If so it would not be surprising that a warming climate in other areas induces self-fertility.

Despite the belief that pear trees are self sterile, I have observed
evidence that they become self fertile after experiencing a period of
producing no fruit/seed. As I mentioned in an earlier email (several
years ago), I know a fellow who had a single pear producing tree with
no neighbors for miles around - and, consequently, no pear trees.
I had a single pear tree for twenty years that began blooming
after twelve years but produced no fruit. I haven't been able to find
another pear tree for many miles around. When my tree became twenty
years old it produced a few fruits. The following year it produced
nearly 2,000 fruits. Some might argue that there must have been a
nearby pear tree that began blooming at the same time. That might be
a plausible argument if a small quantity of fruits were produced, but
2,000 fruits? Yes it is hypothesis but the evidence suggests that
pears can become self fertile after producing no fruits/seeds for some
years.
