“The Earth is actually about 3 million miles closer to the Sun during northern hemisphere *winter*. “
While true, many would insist it should be the other way around.
And it has been the other way around, a long time ago.
Which is part of the reason that continents in the Northern Hemisphere were covered with ice.

If you are referring to the last ice age which ended about 12,000 years ago, the tilt of the Earth's axis was nowhere near reversed as you seem to be suggesting. In other words, the northern hemisphere was still angled away from the Sun at basically the same angle it is now during its winter. However, the Earth itself may have been further away from the Sun during that period, since the shape of Earth's ellipse changes periodically (gets slightly longer and narrower in a predictable cycle of roughly 100,000 years).
