These days here on the Earth the summer solstice is
near apohelion, which minimizes Northern Hemisphere
heating during the Northern Summer.

Sorry, minimal seasonal variation in insolation occurs when the
equinoxes, not the solstices, are coincident with apo- and
perihelion.

So we are near a maximum, not a minimum. The last maximum
was around the end of the last ice age and we've had one
minimum roughly halfway between then and now, demonstrating
that large scale variation of the Earth's climate are not caused
(at least not soley) by those effects.
