More severe storms would come from global COOLING. That increased

poles
is what causes those severe storms.- A. McIntire


That may be a possibility, but there are other possibilities
that are would make things a lot worse.
More severe storms could come from tropical warming and polar
cooling, which is the opposite of what the climate model press releases
have been attributing to AGW, where the tropics don't warm much, but
the Arctic warms a lot.


It the polar regions were to have clouds all during there long
days and none during their long nights, such severe storms might develop
that would scare us all.

Severe cyclonics are rare in Winter the tropics is cool, rare
in spring because the tropics are cool, scarce in summer because the
arctic is warm, but common in the fall because the cold air both aloft
and from the poles produce big gradients.

Also, there has to be a lot of moisture in the air that can
move toward the center of circulation, and result in precipitation,
because without heavy precipitation there will be no low barometer,
and no high winds.
