Your question is easy to answer.
Earth is on elliptical orbit close to a circle. The difference between perihelion and aphelion does amount to zilch. The weather is affected by axis incline and the wind pattern.
In January, it is hot in Australia, in July over here.
Southern hemisphere has less measuring stations so in average they do not account to much. Also the southern hemisphere has a lot of oceans who tame the temperature extremes.
According to Milankovitch, since the Northern Hemisphere has a lot more dry land, it actually determines the climate of the whole Earth. If Northern Hemisphere gets more sunshine, we get global warming, if less, we get global cooling and ice ages!

1) the “less measuring stations” - that’s a punt on the “scientists” who feed us crap. Their averaging of the world temperature is often a joke.
2) The rest is actually the real science, since great work of Milankovitch during WWII. Now being supplanted by the 1) crap!
“since the Northern Hemisphere has a lot more dry land, it actually determines the climate of the whole Earth. If Northern Hemisphere gets more sunshine, we get global warming, if less, we get global cooling and ice ages!”
Wow. This is clear, simple, super helpful. And I enjoyed learning this. Thank you!
