Appreciable difference? Not really. But a 'calculable' difference. Sure!

Be sure to appreciate the HUGE difference of the landmasses in the northern and southern hemispheres.

The primary way heat "gets into" our atmosphere is via re-radiation from the "ground".

Compare the amount of "ground" between N45° and the North Pole, with that of the amount of "ocean" between S45° and the South Pole.

At perihelion (around 4th Jan.) the southern hemisphere is in summertime, but the southern oceans easily absorb any extra solar energy by being 'a little bit closer to the sun'. It's roughly equivalent to having the energy used by an extra 5000 cars arrive as solar radiation... and for *most* of that solar energy be absorbed by the ocean.

The tiny (almost insignificant) effect the earth's orbital eccentricity has on weather and climate is FAR less than that of our planet's axial tilt and the position of our continental land masses.

But, sure, if some researchers wish to tweak the underlying data used for the Milankovitch cycles, then, fine.

But our world is still on fire, and our children's future will be ashes unless we act now.
