How will global warming affect air pressure in the atmosphere?
In 50 to 80 years time when it has been predicted the water levels will rise ,how much will the air pressure in the mountains change?

It probably wont change. Atmospheric pressure is not absolute, it is a comparison with the pressure applying at sea level at the time. The Standard pressure at sea level is 29.92" 0r 1013 mb.
Pressure reduces at approximately 1mb per 30feet or 10metres,
therefore with an gigantic increase in sea level of 10 metres and that is huge, it effectively wont affect air pressure.

The air pressure is the weight of the column of air sitting over "sea level". This is local sea level - even when there is no sea as in a mountain range.
A rise in global sea level of a metre will, on average, raise the barometric pressure at any point by the equivalent of a metre reduction in altitude. Normal day-to-day fluctuations will however make the difference insignificant.

it may be the same as when ice melts it shrink as it expands when frozen and they say nine tenths of the ice begs and caps are under water so it would be very hard to tell

it will be harder to breath as the wind will get stronger
