May be hot where you are...
But here we have winter and it sure is cold.
As with Mars, the southern hemisphere seasons are in phase with the perihelion/aphelion cycle, so Southern hemispheres have a tendency to enhanced seasonality.
Unlike Mars, the more extensive oceans in the southern hemisphere of Earth buffer that effect, since we have a less continental climate.
Wait till the Milankovich cycle changes things and you will get long cold winters and short hot summers up there in the northern hemisphere. Perhaps this will trigger the next ice age and make global warming seem like a pleasant dream. :-)
