Anonymous — Why do you think if there were no greenhouse gases, that the earth's day /
night temperature variations would be anywhere near the variations observed on the moon?
But it seems rather unlikely the earth's day /
night temperature variations would be as large as we see on the moon!
Not exact matches
Temperature variations are minimal year - round with a
night / day range of 21 - 32ºC (70 - 90ºF).
But presence of Earth ocean is also large factor reducing global
variation in day vs
night temperature.
Although our past two summers have been relatively mild, we certainly experience weeks of
temperatures in the 90s with little
temperature variation at
night and continued high humidity.
Willis Eschenback notes a relative + / - 0.5 deg C (1 deg C range)
variation in sea
temperature from day to
night.
The warming trend showed up as a decrease in cold
nights and an increase in warm
nights, meaning effectively that the diurnal (across 24 hours)
temperature variation is narrowed.
It should also be possible to get less snow with the same amount of precipitation if e.g. the day -
night variation increases, in that snow melts during the heat of the day and even if the cold of the
night averages out the
temperature, the added cold can not remake the lost snow.
