DISCLAIMER: This question was closed on Astronomy Stack Exchange as off topic, so I'll try my luck here.
I'm trying to understand the climatic effects of the far future scenario of an Earth-like planet with a reduced rotational speed caused by tidal locking with the moon (day-night period of 28 days, one hemisphere always facing the moon, the other never facing the moon).
I understand that observations of the moon's surface temperature have shown day temperatures of 120°C and freezing cold nights of -230°C.
How would the day and night temperatures of tidal-locked Earth vary?
I am also interested in climatic effects caused by the reduced tides, coriolis force, increased evaporation, but this may reasonably be outside the scope of this question and it's answers.
