Default No antennae radiate all the power fed to them!

Assuming this equation is correct, the temperature of the object
described is just 4 °C at Earth's orbit. Of course the earth is warmer
because it is warmed from the inside as well as from the sun.


That's part of it. But it's also because the Earth doesn't radiate all
that well, either. It holds a fair amount of the heat that strikes it.
Air is a great insulator


Also, greenhouse efeect, skewing the ratio of heat gained vs heat lost... The
UK just had a half-week of mid summer temps at Halloween. Never mind 'weather


Recorded temperatures have always set new records. Just considering one
location, there are 365 days in a year and so 730 high and low records
to test. We have been recording temperatures for roughly 200 years.
What are the chances we *won't* set a new record for one of those dates
in a given year?
