No change. Here in the northern hemisphere, the sun is closest during our winter and further away during our summer because of the elliptical nature of our orbit around the sun.
It’s not the closeness to the sun that causes summer or winter, but the tilt of the earth. That tilt causes summer days to be longer, and winter days to be shorter, and that is far more important than 1% of a solar unit from the sun.
See the image below, and remember, at the Aphelion (greatest distance of our orbit around the sun) is summer in the northern hemisphere, and Perihelion (the shortest distance from the sun) is our winter in the northern hemisphere.
