In contrast, during the summer at high latitudes, the troposphere warms significantly as a result of the long hours of daylight; however, owing to the oblique angle of
the sunlight near the poles, the temperatures there remain relatively cool compared with middle latitudes.

According to The Washington Post's report, Amazon aims to develop a lunar spacecraft with a lander that would dock
near the Shackleton Crater, located at the moon's south
pole, a place with water and
sunlight.
Now, NASA's MESSENGER spacecraft, which has orbited Mercury since March, has confirmed that these radar - bright patches neatly coincide with deep crater floors
near the
poles that never receive any
sunlight at all.
But with more
sunlight hitting
near the equator than at the
poles, it wasn't clear how enough energy could arrive at high latitudes.
The floors of some deep craters
near the
poles are never exposed to direct
sunlight, and temperatures there remain far lower than the global average.
However, layers of water ice, up to a few hundred meters thick, are permanently shielded from
sunlight in craters (shown above in black)
near Mercury's
poles.10 How strange.
Another important corollary of this is that the Arctic sea ice minimum and maximum are nearly irrelevant to climate, because they both occur
near the equinox when no
sunlight is reaching the
pole.
Re: sea ice minimum and maximum are nearly irrelevant to climate, because they both occur

Of course,
Sunlight is available for only half the day and less of it falls on each square meter of surface
near the
poles than
near the equator.
