re: Average temperatures
"Now, tell me within 1 degree Centigrade HOW much hotter Venus is than Earth."
Where?
On both Earth and Venus.
And why there?
Venusian might want us measuring at the bottom of our oceans. Martians might want it done on Earth at 100,000'.
Lava lizards might want the lava temperatures.
Earthlings seem to want it done in little wooden boxes painted white and 5' of the ground- and not near buildings or trees [and no where near lava].
